    This study investigated the effectiveness of a southern state's department of education program to improve science achievement through embedded professional development of science teachers in the lowest performing schools. The Science Mentor Program provided content and inquiry-based coaching by teacher leaders to science teachers in their own classrooms. The study analyzed the mean scale scores for the science portion of the state's high school graduation test for the years 2004 through 2007 to determine whether schools receiving the intervention scored significantly higher than comparison schools receiving no intervention. The results showed that all schools achieved significant improvement of scale scores between 2004 and 2007, but there were no significant performance differences between intervention and comparison schools, nor were there any significant differences between various subgroups in intervention and comparison schools. However, one subgroup, economically disadvantaged (ED) students, from high-level intervention schools closed the achievement gap with ED students from no-intervention schools across the period of the study. The study provides important information to guide future research on and design of large-scale professional development programs to foster inquiry-based science.

    The purpose of this study was to establish a research base from which strategies could be developed for improving science education in Yemen. The study measured the achievement in general science of Yemeni students attending primary, preparatory, and secondary schools, and their counterparts attending three- or five-year education programs in primary teacher training institutions. A sample of 1,984 students from six major cities in Yemen was given the Second International Science Study test in May 1988. Achievement scores of these selected groups were compared. The mean achievement in general science was 11.93 for science track students, 9.21 for three-year teacher training institution students, and 8.49 for five-year teacher training institution students. These mean scores were based on a total of 35 items. This low level of achievement was further verified by making comparisons of the achievement of selected groups from Yemeni high schools in six cities with each other. The following factors were measured in this study: location, grade level, gender and type of science program studied. Selected groups from Yemeni high schools were also compared to their peers in other nations. The researcher compared students of the science track and teacher training institutions to their counterparts in 13 nations and students of the literature track to their counterparts in eight nations. Fifth and ninth grade students' scores were compared with the scores of their counterparts in 15 and 17 nations respectively. In every comparison, every Yemeni group ranked at the bottom of the achievement list. (Jacobson W., & Doran, R. 1988) The outcomes of this research indicate the profound need for improving science programs in all grade levels in Yemen. The research recommendations for improvement in science education in Yemen fall into four areas: a change in attitudes toward education, a change in teacher education, a change in classroom conditions, and a change in educational

    Although countries worldwide are emphasizing the importance of science education for technological development and global economic competition, comparative findings from standardized international student assessments reveal a huge gap in science scores between developed and developing countries. Certain developed economies too have made little progress in raising science achievement over the past decade. Despite school improvement being placed high on the policy agenda, the results of such actions have been poor. Therefore, there is a need to explore additional ways in which science achievement can be enhanced. This study focuses on the family and examines whether parents' attitudes towards science (how much they value science and the importance they place on it) can influence their children's science achievement. Individual- and school-level data are obtained from the Program for International Student Assessment 2006 survey for 15 Organisation for Economic Co-operation and Development (OECD) and non-OECD countries. Hierarchical linear modelling is employed to estimate the equations. The findings indicate that parents' attitudes towards science have a positive and statistically significant effect on science achievement, after controlling for other important student- and school-level variables. Moreover, students from poor backgrounds appear to benefit from more positive parental science attitudes as much as students from high socioeconomic status, such that equality of student achievement is not affected. This study recommends that schools and teachers encourage parents to play a more pro-active role in their children's science education, as well as educate parents about the importance of science and strategies that can be adopted to support their children's science learning.

  5. Comparison of student achievement among two science laboratory types: traditional and virtual

    Reese, Mary Celeste

    Technology has changed almost every aspect of our daily lives. It is not surprising then that technology has made its way into the classroom. More and more educators are utilizing technological resources in creative ways with the intent to enhance learning, including using virtual laboratories in the sciences in place of the "traditional" science laboratories. This has generated much discussion as to the influence on student achievement when online learning replaces the face-to-face contact between instructor and student. The purpose of this study was to discern differences in achievement of two laboratory instruction types: virtual laboratory and a traditional laboratory. Results of this study indicate statistical significant differences in student achievement defined by averages on quiz scores in virtual labs compared with traditional face-to-face laboratories and traditional laboratories result in greater student learning gains than virtual labs. Lecture exam averages were also greater for students enrolled in the traditional laboratories compared to students enrolled in the virtual laboratories. To account for possible differences in ability among students, a potential extraneous variable, GPA and ACT scores were used as covariates.

  6. What factors help or hinder the achievement of low SES students? An international comparison using TIMSS 2011 8th grade science data

    Bruner, Justin L.

    Focusing on science from a cross-country perspective, this study explores the relationship between 8th grade science achievement and student, teacher, and school characteristics. More specifically, this study will pay special attention to low socio-economic status (SES) students and seek to understand why some disadvantaged students are able to have higher than expected achievement in science given their SES while other disadvantaged students are not able to achieve beyond what would be expected given their background. This study will explore the multi-level relationship between the characteristics of students, their teachers, their schools, and student achievement in science. While looking at students in classrooms and in schools, this work will create as precise as possible a measure of student SES by drawing on recommendations of an expert panel commissioned by the National Association of Educational Progress (NAEP) study. The study uses the most recent cycle (2011) of the Trends in International Math and Science Study (TIMSS), to strategically select a six-country sample from the 45 participating countries. This six-country sample was selected by using the country level achievement and the standard deviation of that achievement. This will create a sample that has a range of equality in achievement and strength in achievement. This allows for making comparisons both across and within countries to better understand variations in the factors of student performance, especially for disadvantaged students. This paper builds on the existing research around socio-economic status (SES) and achievement by exploring in more detail the conditions in schools and classrooms around the world that might magnify or reduce the effect of SES on student achievement. The analysis looks at these questions: "What conditions help low SES students achieve higher than what would be expected given their SES?" and "What conditions hinder low SES students to achieve at or below what would

  7. A comparison of rural high school students in Germany with rural Tennessee high school students' mathematics and science achievement

    Harding, R. Fredrick

    This descriptive study compared the science and mathematics aptitudes and achievement test scores for the final school year students in rural White County and Van Buren County, Tennessee with rural county students in Germany. In accordance with the previous research literature (Stevenson, 2002), German students outperformed U.S. students on The International Trends in Math and Science test (TIMSS). As reform in the U.S. education system has been underway, this study intended to compare German county student final school year performance with White County and Van Buren County (Grade 12) performance in science and mathematics. The entire populations of 176 White and Van Buren Counties senior high final school year students were compared with 120 school final year students from two rural German county high schools. The student responses to identical test and questionnaire items were compared using the t-test statistical analysis. In conclusion after t-test analyses, there was no significant difference (p>.05 level) in student attitudes on the 27 problem achievement and the 35 TIMSS questionnaire items between the sampled population of 120 German students compared with the population of 176 White and Van Buren students. Also, there was no statistically significant difference (p>.05 level) between the German, White, and Van Buren County rural science and math achievement in the TIMSS problem section of the final year test. Based on the research, recommendations to improve U.S. student scores to number one in the world include making changes in teaching methodology in mathematics and science; incorporating pamphlet lessons rather than heavily reliance on textbooks; focusing on problem solving; establishing an online clearinghouse for effective lessons; creating national standards in mathematics and science; matching students' course choices to job aspirations; tracking misbehaving students rather than mainstreaming them into the regular classroom; and designing

    The aim of this study was to evaluate attitudes towards and achievement in science of Form 3 students studying in single-sex and coeducational schools in Brunei. The results demonstrated significant differences in attitudes towards and achievement in science of male and female students in single-sex schools and students in coeducational schools. These differences were at moderate level. In single-sex schools, the girls achieved moderately better in science than the boys despite their attitudes were only marginally better than the boys. However, there were no gender differences in attitudes towards and achievement in science of students in coeducational schools. The attitudes towards and achievement in science of girls in single-sex schools were moderately better than those of girls in coeducational schools. Whereas the attitudes towards and achievement in science of boys in single-sex schools were only marginally better than the boys in coeducational schools. However, further research to investigate (a) if these differences are repeated at other levels as well as in other subjects, and (b) the extent to which school type contributed towards these differences is recommended.

    Full Text Available The paper considers the main results and some educational implications of the TIMSS 2003 assessment conducted in Serbia in the fields of the science achievement of Serbian eighth grade students and the science curriculum context of their achievement. There were 4264 students in the sample. It was confirmed that Serbian eighth graders had made average scale score of 468 points in the science, and with this achievement they are placed in the zone of the top of low international benchmarking level, very close to the point of intermediate benchmark. The average science achievement of the Serbian eighth graders is somewhat below the general international science achievement. The best results were achieved in the science content domain of "chemistry", and the lower results in the content domain of "environmental science". Across the defined science cognitive domains, it was confirmed that the Serbian students had achieved the best results in cognitive domain of "factual knowledge" and weaker results in "reasoning and analysis". The achieved results raise many questions about contents of the science curriculum in Serbia, its overall quality and basic characteristics of its implementation. These results can be eligibly used to improve the science curricula and teaching in Serbian primary school. .

    2017-07-01

    This research investigated teacher learning and teacher beliefs in a two-year technology professional development (TPD) for teachers and its impact on their student achievement in science in the western part of the United States. Middle-school science teachers participated in TPD focused on information communication technologies (ICTs) and their applications in science inquiry pedagogy. Three self-reporting teacher instruments were used alongside their student achievement scores on the end-of-year state-science-test. The teacher self-reporting measures investigated technological literacy, ICT capabilities, and pedagogical beliefs about science inquiry pedagogy. Data were collected every year, and descriptive statistics, t-tests, and Pearson's correlations were used for analysis. We found teachers' technological skills and ICT capabilities increasing over time with significant gains each year. Additionally, teachers' pedagogical beliefs changed to become more science inquiry oriented over time; however, the gains were not significant until after the second year of TPD. Comparisons of teacher learning and belief measures with student achievement revealed that the students' performance was correlated to teachers' pedagogical beliefs about science inquiry, but not to their technological skills nor to their ICT capabilities. This research suggests that pedagogical considerations should be foregrounded in TPD and that this may require more longitudinal TPD to ensure that technology integration in science instruction is consequential to student learning.

  13. Structure of Black Male Students Academic Achievement in Science

    Science.gov (United States)

    Rascoe, Barbara

    Educational policies and practices have been largely unsuccessful in closing the achievement gap between Black and White students "Schwartz, 2001". This achievement gap is especially problematic for Black students in science "Maton, Hrabrowski, - Schmitt, 2000. Given the fact that the Black-White achievement gap is still an enigma, the purpose of this article is to address the Black female-Black male academic achievement gap in science majors. Addressing barriers that Black male students may experience as college science and engineering majors, this article presents marketing strategies relative to politics, emotional intelligence, and issues with respect to how science teaching, and Black male students' responses to it, are different. Many Black male students may need to experience a paradigm shift, which structures and enhances their science achievement. Paradigm shifts are necessary because exceptional academic ability and motivation are not enough to get Black males from their first year in a science, technology, education, and mathematics "STEM" major to a bachelor's degree in science and engineering. The conclusions focus on the balance of truth-slippery slopes concerning the confluence of science teachers' further ado and Black male students' theories, methods, and values that position their academic achievement in science and engineering majors.

  14. Performance on large-scale science tests: Item attributes that may impact achievement scores

    Gordon, Janet Victoria

    Significant differences in achievement among ethnic groups persist on the eighth-grade science Washington Assessment of Student Learning (WASL). The WASL measures academic performance in science using both scenario and stand-alone question types. Previous research suggests that presenting target items connected to an authentic context, like scenario question types, can increase science achievement scores especially in underrepresented groups and thus help to close the achievement gap. The purpose of this study was to identify significant differences in performance between gender and ethnic subgroups by question type on the 2005 eighth-grade science WASL. MANOVA and ANOVA were used to examine relationships between gender and ethnic subgroups as independent variables with achievement scores on scenario and stand-alone question types as dependent variables. MANOVA revealed no significant effects for gender, suggesting that the 2005 eighth-grade science WASL was gender neutral. However, there were significant effects for ethnicity. ANOVA revealed significant effects for ethnicity and ethnicity by gender interaction in both question types. Effect sizes were negligible for the ethnicity by gender interaction. Large effect sizes between ethnicities on scenario question types became moderate to small effect sizes on stand-alone question types. This indicates the score advantage the higher performing subgroups had over the lower performing subgroups was not as large on stand-alone question types compared to scenario question types. A further comparison examined performance on multiple-choice items only within both question types. Similar achievement patterns between ethnicities emerged; however, achievement patterns between genders changed in boys' favor. Scenario question types appeared to register differences between ethnic groups to a greater degree than stand-alone question types. These differences may be attributable to individual differences in cognition

  15. Science access, career choices, achievement, and motivation: Perceptions of female science olympians

    Price, Kelly Rae

    Women remain under-represented in science career fields and this is especially evident in the physical sciences. Female students maintain equal science interest and achievement to male students in elementary school but by middle and high school they fall behind their male peers. Reasons cited for girls' declining interest in science include battling traditional gender stereotypes, lack of encouragement, and lack of female role models. Four main science concerns related to girls/women as indicated by research literature were science access, career choices, achievement, and motivation. In Georgia, some girls have made a break from the research trends by demonstrating their fervor for science through participation in the academic activity, Science Olympiad. The purpose of this study was to examine the science perceptions of girls who demonstrated science success by their participation in Science Olympiad. Utilizing phenomenological and feminist perspectives, the qualitative research method of focus group interviewing was used to address the research questions comprising the four science concerns of female science access, career choices, achievement, and motivation. The study participants were all girls/women who participated in Science Olympiad. A total of five focus groups were studied. One of the focus groups had current college undergraduates, former Science Olympians, in it while the others were composed of high school girls. Through the description of their science experiences, the participants shared their perceptions of the four science concerns. When addressing these science concerns, the participants revealed four factors that had most affected their science perceptions: the importance of support, science needs Serious Fun, teachers matter, and the bonuses of extracurricular involvement. In their experiences, the participants found success in science because they had teachers, parents, and peers who supported their academic interests, including science, and

    Johnson, Ursula Yvette

    This study examined science achievement growth across elementary and middle school and parent school involvement using the Early Childhood Longitudinal Study - Kindergarten Class of 1998--1999 (ECLS-K). The ECLS-K is a nationally representative kindergarten cohort of students from public and private schools who attended full-day or half-day kindergarten class in 1998--1999. The present study's sample (N = 8,070) was based on students that had a sampling weight available from the public-use data file. Students were assessed in science achievement at third, fifth, and eighth grades and parents of the students were surveyed at the same time points. Analyses using latent growth curve modeling with time invariant and varying covariates in an SEM framework revealed a positive relationship between science achievement and parent involvement at eighth grade. Furthermore, there were gender and racial/ethnic differences in parents' school involvement as a predictor of science achievement. Findings indicated that students with lower initial science achievement scores had a faster rate of growth across time. The achievement gap between low and high achievers in earth, space and life sciences lessened from elementary to middle school. Parents' involvement with school usually tapers off after elementary school, but due to parent school involvement being a significant predictor of eighth grade science achievement, later school involvement may need to be supported and better implemented in secondary schooling.

  18. Aspects of science engagement, student background, and school characteristics: Impacts on science achievement of U.S. students

    Science.gov (United States)

    Grabau, Larry J.

    Science achievement of U.S. students has lagged significantly behind other nations; educational reformers have suggested science engagement may enhance this critical measure. The 2006 Program for International Student Assessment (PISA) was science-focused and measured science achievement along with nine aspects of science engagement: science self-efficacy, science self-concept, enjoyment of science, general interest in learning science, instrumental motivation for science, future-oriented science motivation, general value of science, personal value of science, and science-related activities. I used multilevel modeling techniques to address both aspects of science engagement and science achievement as outcome variables in the context of student background and school characteristics. Treating aspects of science engagement as outcome variables provided tests for approaches for their enhancement; meanwhile, treating science achievement as the outcome variable provided tests for the influence of the aspects of science engagement on science achievement under appropriate controls. When aspects of science engagement were treated as outcome variables, gender and father's SES had frequent (significant) influences, as did science teaching strategies which focused on applications or models and hands-on activities over-and-above influences of student background and other school characteristics. When science achievement was treated as the outcome variable, each aspect of science engagement was significant, and eight had medium or large effect sizes (future-oriented science motivation was the exception). The science teaching strategy which involved hands-on activities frequently enhanced science achievement over-and-above influences of student background and other school characteristics. Policy recommendations for U.S. science educators included enhancing eight aspects of science engagement and implementing two specific science teaching strategies (focus on applications or models

    This study employs the 2004 School Achievement Indicators Program (SAIP) data to examine whether academic effort manifested by greater investments in school and homework does result in higher literacy scores in science for Canadian students. The study compares four gender-immigrant profiles: Canadian-born males, immigrant males, Canadian-born females, and immigrant females on their scores on teacher-assigned grades in science and on the SAIP science literacy test, and across a range of dispositions, beliefs, and behaviors suggested in the literature as predictive of achievement in science. Study findings show that Canadian-born students, particularly boys, have higher performance in the science literacy test despite their lower achievement in the science classroom and the least investments of time in doing science homework. In contrast, immigrant female students demonstrate the highest academic effort and achievement in science courses which are not matched by similar results in the science literacy test. We discuss these results in relation to different socialization experiences with science and technology that limit female and immigrant students' abilities to transfer knowledge to new situations that have not been learned in the classroom.

    Martinez, Alina

    The importance of science in today's technological society necessitates continued attention to students' experiences in science and specifically their achievement in science. There is a need to look at gender and race/ethnicity simultaneously when studying students' experiences in science and to explore factors related to higher achievement among students. Using data from the Longitudinal Study of American Youth, this study contributes to existing literature on student achievement in science by simultaneously exploring the effects of race/ethnicity and gender. Capitalizing on the availability of yearly science achievement scores, I present trajectories of student achievement from 7th to 12th grade. This study also includes an exploration of school effects. Overall, student achievement in science increases from 7th to 12th grade, although some leveling is seen in later grades. Growth in achievement differs by both gender and race/ethnicity, but racial/ethnic differences are larger than gender differences. Hispanic, Black, Asian, and White males score higher, on average, throughout the secondary grades than their female counterparts. Achievement scores of Asian students are consistently higher than White students, who in turn score higher than Hispanic and finally Black students. Both background and science-related factors help explain variation in achievement status and growth in achievement. Parental education is positively associated with achievement status among all groups except Black students for whom there is no effect of parental education. Science related resources in the home are positively associated with student achievement and the effect of these resources increases in later grades. Student achievement in science is also positively related to student course taking and attitude toward science. Furthermore, both the negative effect of viewing science as a male domain, which exists for males and females, and the positive effect of parental support for

    Steakley, Carrie Capers

    This study investigated the effects of a high school science intervention program that included hands-on activities, science-related career information and exposure, and real-world experiences on girls' attitudes and achievement in science. Eighty-four girls, 44 ninth-graders and 40 tenth-graders, and 105 parents participated in the study. Survey data was collected to assess the girls' attitudes toward science in seven distinct areas: social implications of science, normality of scientists, attitude toward scientific inquiry, adoption of scientific attitudes, enjoyment of science lessons, leisure interest in science, and career interest in science. Additional questionnaires were used to determine the extent of the girls' participation in sports and the attitudes of their parents toward science. The girls' cumulative science semester grade point averages since the seventh grade were used to assess academic science achievement. This study found no evidence that participation in the program improved the girls' attitudes or achievement in science. Parent attitudes and years of participation in sports were not accurate predictors of science achievement. Additionally, no significant relationship was detected between the girls' and their parents' perceptions of science. However, the study did suggest that extended participation in sports may positively affect science achievement for girls. This study holds implications for educational stakeholders who seek to implement intervention methods and programs that may improve student attitudes and achievement in science and attract more youth to future science-related careers.

  4. Self-regulated learning and science achievement in a community college

    Maslin, (Louisa) Lin-Yi L.

    Self-regulated learning involves students' use of strategies and skills to adapt and adjust towards achievement in school. This research investigates the extent to which self-regulated learning is employed by community college students, and also the correlates of self-regulated learning: Is it used more by students in advanced science classes or in some disciplines? Is there a difference in the use of it by students who complete a science course and those who do not? How does it relate to GPA and basic skills assessments and science achievement? Does it predict science achievement along with GPA and assessment scores? Community college students (N = 547) taking a science course responded to the Motivated Strategies for Learning Questionnaire (MSLQ). The scales measured three groups of variables: (1) cognitive strategies (rehearsal, elaboration, organization, and critical thinking); (2) metacognitive self-regulation strategies (planning, monitoring, and self-regulation); and (3) resource management strategies (time and study environment, effort regulation, peer learning, and help-seeking). Students' course scores, college GPA, and basic skills assessment scores were obtained from faculty and college records. Students who completed a science course were found to have higher measures on cumulative college GPAs and assessment scores, but not on self-regulated learning. Self-regulated learning was found not to be used differently between students in the advanced and beginning science groups, or between students in different disciplines. The exceptions were that the advanced group scored higher in critical thinking but lower in effort regulation than the beginning group. Course achievement was found to be mostly unrelated to self-regulated learning, except for several significant but very weak and negative relationships in elaboration, self-regulation, help-seeking, and effort regulation. Cumulative GPA emerged as the only significant predictor of science achievement

    Waller, Samara Susan

    This study addressed a prevalence of low achievement in science courses in an urban school district in Georgia. National leaders and educators have identified the improvement of science proficiency as critical to the future of American industry. The purpose of this study was to examine parent involvement in this school district and its contribution to the academic achievement of successful science students. Social capital theory guided this study by suggesting that students achieve best when investments are made into their academic and social development. A collective case study qualitative research design was used to interview 9 parent participants at 2 elementary schools whose children scored in the exceeds category on the Science CRCT. The research questions focused on what these parents did at home to support their children's academic achievement. Data were collected using a semi-structured interview protocol and analyzed through the categorical aggregation of transcribed interviews. Key findings revealed that the parents invested time and resources in 3 practices: communicating high expectations, supporting and developing key skills, and communicating with teachers. These findings contribute to social change at both the local and community level by creating a starting point for teachers, principals, and district leaders to reexamine the value of parent input in the educational process, and by providing data to support the revision of current parent involvement policies. Possibilities for further study building upon the findings of this study may focus on student perceptions of their parents' parenting as it relates to their science achievement.

  7. Promoting the achievement of girls in GCSE science

    Morton, Kevin Charles

    This study, designed to challenge the under-representation and limited attainment of girls in the physical sciences in an 11-16 comprehensive school, was suggested by research into attitude formation by Kelly et al in the early 1980s. Balanced science, in removing opportunities for girls to opt out of the physical sciences, made it essential to identify those factors which were adversely affecting girls' attitudes towards science.Preliminary research tasks investigated stereotypical attitudes towards science activities and the school curriculum amongst students and their parents. Additional research probed students' perceptions of their ability in science and the relevance of science subjects. Students' attitudes towards science and science teaching were investigated in relation to their option and career choices. These data influenced the choice of MEG Coordinated Science (The Suffolk Development) as the GCSE balanced science course for the school.The subsequent programme of action research included a series of small-scale investigations, involving both monitoring and evaluation, designed to develop the Suffolk scheme and satisfy the research aims. Student attitudes towards teaching methods and the Suffolk materials were amongst those areas investigated. After evaluation the findings were channelled into the action research spiral to integrate teaching methods and curriculum development thereby promoting the attitudes and achievement of the girls.Improvements in attainment by all students, particularly the girls, were illustrated by increasing GCSE success. Although the traditional pattern of boys' superiority within the physical sciences was markedly reduced the research demonstrated that it is possible to improve the attainment of girls within GCSE science without discriminating against boys.Student opinion and the GCSE data suggested that the girls' achievements could be partially explained by the coursework-led assessment which suited the girls' preferred

    This quantitative study examined science interest and achievement of middle school minority females in both traditional science classes and Problem-based Learning (PBL) science classes. The purpose of this study was to determine if there is a significant difference between traditional teaching and the PBL teaching method. The researcher also looked for a significant relationship between interest in science and achievement in science. This study used survey data from parents of female middle school science students to measure student interest in science concepts. The population of interest for this study was 13--15 year old eighth grade females from various racial make-ups such as, African American, Hispanic, Bi-racial, Asian, and Other Pacific Islander. Student achievement data was retrieved from the 8th grade science fall common assessed benchmark exam of both test groups. The results of the survey along with the benchmark data was to shed light on the way adolescent females learn and come to embrace science. The findings may provide guidance for science educators seeking to reach their minority female students and guide their achievement levels higher than before. From the results of the t-test and Pearson correlation test of this study, it can be concluded that while this study did not show a significant difference in academic achievement or interest between the two teaching styles, it revealed that interest in science has a positive role to play in the academic success of minority girls in science. The practical implications for examining these issues are to further the research on solutions for closing the minority and gender achievement gaps. The results of this study have implications for researchers as well as practitioners in the field of education.

    Prior research indicates that technology has had little effect on raising student achievement. Little empirical research exists, however, studying the effects of technology as a tool to improve student achievement through development of higher order thinking skills. Also, prior studies have not focused on the manner in which technology is being used in the classroom and at home to enhance teaching and learning. Empirical data from a secondary school representative of those in California were analyzed to determine the effects of technology on student science achievement. The quantitative analysis methods for the school data study included a multiple linear path analysis, using final course grade as the ultimate exogenous variable. In addition, empirical data from a nationwide survey on how Americans use the Internet were disaggregated by age and analyzed to determine the relationships between computer and Internet experience and (a) Internet use at home for school assignments and (b) more general computer use at home for school assignments for school age children. Analysis of data collected from the a "A Nation Online" Survey conducted by the United States Census Bureau assessed these relationships via correlations and cross-tabulations. Finally, results from these data analyses were assessed in conjunction with systemic reform efforts from 12 states designed to address improvements in science and mathematics education in light of the Third International Mathematics and Science Survey (TIMSS). Examination of the technology efforts in those states provided a more nuanced understanding of the impact technology has on student achievement. Key findings included evidence that technology training for teachers increased their use of the computer for instruction but students' final science course grade did not improve; school age children across the country did not use the computer at home for such higher-order cognitive activities as graphics and design or spreadsheets

    As the new millennium approaches, a long anticipated reckoning for the education system of the United States is forthcoming, Years of school reform initiatives have not yielded the anticipated results. A particularly perplexing problem involves the lack of significant improvement of student achievement in math and science. Three "Partnership" projects represent collaborative efforts between Xavier University (XU) of Louisiana, Southern University of New Orleans (SUNO), Mississippi Valley State University (MVSU), and the National Aeronautics and Space Administration (NASA), Stennis Space Center (SSC), to enhance student achievement in math and science. These "Partnerships" are focused on students and teachers in federally designated rural and urban empowerment zones and enterprise communities. The major goals of the "Partnerships" include: (1) The identification and dissemination of key indices of success that account for high performance in math and science; (2) The education of pre-service and in-service secondary teachers in knowledge, skills, and competencies that enhance the instruction of high school math and science; (3) The development of faculty to enhance the quality of math and science courses in institutions of higher education; and (4) The incorporation of technology-based instruction in institutions of higher education. These goals will be achieved by the accomplishment of the following objectives: (1) Delineate significant ?best practices? that are responsible for enhancing student outcomes in math and science; (2) Recruit and retain pre-service teachers with undergraduate degrees in Biology, Math, Chemistry, or Physics in a graduate program, culminating with a Master of Arts in Curriculum and Instruction; (3) Provide faculty workshops and opportunities for travel to professional meetings for dissemination of NASA resources information; (4) Implement methodologies and assessment procedures utilizing performance-based applications of higher order

    Chandrasena, Wanasinghe Durayalage

    This research comprises three inter-related synergistic studies. Study 1 aims to develop a psychometrically sound tool to measure secondary students' science self-concepts, motivation, and aspirations in biology, chemistry, earth and environmental methodology to explicate students' and teachers' views, practices, and personal experiences, to identify the barriers to undertaking science for secondary students and to provide rich insights into the relations of secondary students' science self-concepts and motivation with their aspirations and achievement. Study 3 will detect additional issues that may not necessarily be identifiable from the quantitative findings of Study 2. The psychometric properties of the newly developed instrument demonstrated that students' science self-concepts were domain specific, while science motivation and science aspirations were not. Students' self-concepts in general science, chemistry, and physics were stronger for males than females. Students' self-concepts in general science and biology became stronger for students in higher years of secondary schooling. Students' science motivation did not vary across gender and year levels. Though students' science aspirations did not vary across gender, they became stronger with age. In general, students' science self-concepts and science motivation were positively related to science aspirations and science achievement. Specifically, students' year level, biology self-concept, and physics self concept predicted their science and career aspirations. Biology self-concept predicted teacher ratings of students' achievement, and students' general science self-concepts predicted their achievement according to students' ratings. Students' year level and intrinsic motivation in science were predictors of their science aspirations, and intrinsic motivation was a greater significant predictor of students' achievement, according to student ratings. Based upon students' and teachers' perceptions, the

    This study aimed to examine whether the relationships among family resources, school climate, learning participation, science attitude, and science achievement are different between primary school students and junior high school students within one educational system. The subjects included 4,181 Grade 4 students and 5,074 Grade 8 students who participated in TIMSS 2003 in Taiwan. Using structural equation modeling, the results showed that family resources had significant positive effects for both groups of learners. Furthermore, a context effect for the structural relationship between school climate, learning participation, and science achievement was revealed. In the primary school context, Grade 4 students who perceived positive school climate participated in school activities more actively, and had better science performance. However, in the secondary school context, learning participation had a negative impact and led to lower science achievement. The implications about this result in relation to the characteristics of the two educational contexts in Taiwan were further discussed.

  13. Measuring more than we know? An examination of the motivational and situational influences in science achievement

    Haydel, Angela Michelle

    The purpose of this dissertation was to advance theoretical understanding about fit between the personal resources of individuals and the characteristics of science achievement tasks. Testing continues to be pervasive in schools, yet we know little about how students perceive tests and what they think and feel while they are actually working on test items. This study focused on both the personal (cognitive and motivational) and situational factors that may contribute to individual differences in achievement-related outcomes. 387 eighth grade students first completed a survey including measures of science achievement goals, capability beliefs, efficacy related to multiple-choice items and performance assessments, validity beliefs about multiple-choice items and performance assessments, and other perceptions of these item formats. Students then completed science achievement tests including multiple-choice items and two performance assessments. A sample of students was asked to verbalize both thoughts and feelings as they worked through the test items. These think-alouds were transcribed and coded for evidence of cognitive, metacognitive and motivational engagement. Following each test, all students completed measures of effort, mood, energy level and strategy use during testing. Students reported that performance assessments were more challenging, authentic, interesting and valid than multiple-choice tests. They also believed that comparisons between students were easier using multiple-choice items. Overall, students tried harder, felt better, had higher levels of energy and used more strategies while working on performance assessments. Findings suggested that performance assessments might be more congruent with a mastery achievement goal orientation, while multiple-choice tests might be more congruent with a performance achievement goal orientation. A variable-centered analytic approach including regression analyses provided information about how students, on

    Brooks, Tanisha

    Many girls continue to achieve below their male counterparts and portray negative attitudes towards science classes. Some school districts are using single-gender education as a way to shrink the gender gap in school achievement and science related attitude. The purpose of this study was to compare achievement and science-related attitudes of 7th grade girls in single-gender education to 7th grade girls in mixed-gender education. The theoretical base for this study included knowledge from brain-based learning and assimilation, accommodation and age factors of Piaget's theory of cognitive development. The 12-week study included 48 7th grade girls, 21 in the single-gender classroom and 14 in each mixed-gender classroom. This quantitative randomized posttest only control group design utilized the TerraNova Science Assessment and the Test of Science Related Attitudes. Analysis of Variance (ANOVA) was used to determine if significant differences existed in the achievement and attitudes of girls in single and mixed-gender science classes. ANOVA analyses revealed that the girls in the single-gender classroom showed a significantly higher achievement level when compared to girls in the mixed-gender classrooms. Results showed no significant difference in attitude between the two groups. The results of this study contribute to social change by raising awareness about gender issues in science achievement and attitude, addressing a deficiency in the single-gender science education literature, and assisting educational systems in decision making to address achievement gaps while moving toward adequate yearly progress and meeting the requirements of the No Child Left Behind Act of 2001.

  17. Science homework with video directions for parents: The impact on parental involvement and academic achievement

    Hooker, Kathy L.

    The benefits of effective parental involvement in education have been well documented and can be far reaching. When educators make an effort to involve families, parental involvement can be even more meaningful. Homework is a commonly practiced and accepted connection between school and home and affords parents many opportunities to interact with their children on educational endeavors. However, parental involvement may be limited because educators do not reach out to parents, parents feel their children do not need their help, or parents are unfamiliar with the content and therefore unable to help. The purpose of this study was too develop and implement a tool to enhance parental involvement and academic achievement of fourth grade science students. The tool used in this study was a weekly science video to be viewed by parents when it accompanied science homework assignments. To begin, the researcher created six science videos for parents to watch that supplemented weekly homework assignments. Consequently, the researcher set up treatment and comparison groups to test the effectiveness of the supplemental videos in terms of parental involvement and academic achievement. A mixed methods approach was used to collect data from parents and students throughout the study. A combination of quantitative and qualitative data was collected throughout this study from both parents and students. Additionally, data was collected from a variety of sources including baseline, midpoint, and endpoint surveys; scores on homework assignments; and focus group interview sessions with parents and students. Data analysis revealed an overall positive impact on parental involvement and academic achievement when the videos were utilized.

  18. Relationship Between Teacher Inquiry Science Instruction Self-Efficacy and Student Achievement

    Science.gov (United States)

    Hanners, Grace D.

    Standardized test data indicate that student achievement in science is a problem both nationally and locally. At the study site, only a small percentage of fifth-grade students score at the advanced level on the Maryland state science assessment (MSA). In addition, the performance of African American, economically disadvantaged, and special education students is well below that of the general student population. Some studies have shown that teacher self-efficacy affects student achievement. Therefore, the purpose of this study was to explore the relationship between fifth-grade teacher inquiry science instruction self-efficacy scores and the scores of their students on the MSA. Bandura's work on the effect of self-efficacy on human behavior provided the theoretical basis for this study. The research questions examined the relationship between teacher inquiry science instructional self-efficacy scores and students' science MSA scores as well as the relationship by student subgroups. A correlational research design was used. The Teaching Science as Inquiry survey instrument was used to quantify teacher self-efficacy, and archival MSA data were the source for student scores. The study included data from 22 teachers and 1,625 of their students. A 2-tailed Pearson coefficient analysis revealed significant, positive relationships with regard to overall student achievement ( r20 = .724, p < .01) and the achievement of each of the subgroups (African American: r20 = .549, p < .01; economically disadvantaged: r20 = .655, p < .01; and special education: r18 = .532, p < .05). The results of this study present an opportunity for positive social change because the local school system can provide professional development that may increase teacher inquiry science instruction self-efficacy as a possible means to improve overall science achievement and to reduce achievement gaps.

  20. Quality Science Teacher Professional Development and Student Achievement

    Science.gov (United States)

    Dubner, J.

    2007-12-01

    Studies show that socio-economic background and parental education accounts for 50-60 percent of a child's achievement in school. School, and other influences, account for the remaining 40-50 percent. In contrast to most other professions, schools require no real apprenticeship training of science teachers. Overall, only 38 percent of United States teachers have had any on-the-job training in their first teaching position, and in some cases this consisted of a few meetings over the course of a year between the beginning teacher and the assigned mentor or master teacher. Since individual teachers determine the bulk of a student's school experiences, interventions focused on teachers have the greatest likelihood of affecting students. To address this deficiency, partnerships between scientists and K-12 teachers are increasingly recognized as an excellent method for improving teacher preparedness and the quality of science education. Columbia University's Summer Research Program for Science Teachers' (founded in 1990) basic premise is simple: teachers cannot effectively teach science if they have no firsthand experience doing science, hence the Program's motto, "Practice what you teach." Columbia University's Summer Research Program for Science Teachers provides strong evidence that a teacher research program is a very effective form of professional development for secondary school science teachers and has a direct correlation to increased student achievement in science. The author will present the methodology of the program's evaluation citing statistically significant data. The author will also show the economic benefits of teacher participation in this form of professional development.

    2009-06-01

    This longitudinal study of middle school science teachers explored the relationship between effective science instruction, as defined by the National Science Education Standards (NRC in National science education standards. National Academy Press, Washington, DC, 1996), and student achievement in science. Eleven teachers participated in a three year study of teacher effectiveness, determined by the LSC Classroom Observation Protocol (Horizon Research, Inc. in Local Systemic Change Classroom Observation Protocol. May 1, 2002) and student achievement, which was assessed using the Discovery Inquiry Test in Science. Findings in this study revealed the positive impact that effective science teachers have on student learning, eliminating achievement gaps between White and Non-White students. Case studies of three teachers, both effective and ineffective explore the beliefs and experiences that influence teachers to change, or not to change practice. This study provides justification for teaching science effectively to narrow achievement gaps in science and provides insight to stakeholders in science education as to how to support teachers in becoming more effective, through addressing existing teacher beliefs and providing experiences that challenge those beliefs.

  2. Predictors of cultural capital on science academic achievement at the 8th grade level

    Misner, Johnathan Scott

    The purpose of the study was to determine if students' cultural capital is a significant predictor of 8th grade science achievement test scores in urban locales. Cultural capital refers to the knowledge used and gained by the dominant class, which allows social and economic mobility. Cultural capital variables include magazines at home and parental education level. Other variables analyzed include socioeconomic status (SES), gender, and English language learners (ELL). This non-experimental study analyzed the results of the 2011 Eighth Grade Science National Assessment of Educational Progress (NAEP). The researcher analyzed the data using a multivariate stepwise regression analysis. The researcher concluded that the addition of cultural capital factors significantly increased the predictive power of the model where magazines in home, gender, student classified as ELL, parental education level, and SES were the independent variables and science achievement was the dependent variable. For alpha=0.05, the overall test for the model produced a R2 value of 0.232; therefore the model predicted 23.2% of variance in science achievement results. Other major findings include: higher measures of home resources predicted higher 2011 NAEP eighth grade science achievement; males were predicted to have higher 2011 NAEP 8 th grade science achievement; classified ELL students were predicted to score lower on the NAEP eight grade science achievement; higher parent education predicted higher NAEP eighth grade science achievement; lower measures of SES predicted lower 2011 NAEP eighth grade science achievement. This study contributed to the research in this field by identifying cultural capital factors that have been found to have statistical significance on predicting eighth grade science achievement results, which can lead to strategies to help improve science academic achievement among underserved populations.

    2009-05-01

    The aim of this study was twofold: firstly, to investigate the grade level (elementary and middle school) and gender effect on students' motivation in science (perceived academic science self-concept and task value) and perceived family involvement, and secondly to examine the relationship among family environment variables (fathers' educational level, mothers' educational level, and perceived family involvement), motivation, gender and science achievement in elementary and middle schools. Multivariate Analysis of Variance (MANOVA) showed that elementary school students have more positive science self-concept and task value beliefs compared to middle school students. Moreover, elementary school students appeared to perceive more family involvement in their schooling. Path analyses also suggested that family involvement was directly linked to elementary school students' task value and achievement. Also, in elementary school level, significant relationships were found among father educational level, science self-concept, task value and science achievement. On the other hand, in middle school level, family involvement, father educational level, and mother educational level were positively related to students' task value which is directly linked to students' science achievement. Moreover, mother educational level contributed to science achievement through its effect on self-concept.

  4. Learning science in a cooperative setting: Academic achievement and affective outcomes

    Lazarowitz, Reuven; Hertz-Lazarowitz, Rachel; Baird, J. Hugh

    A learning unit in earth science was taught to high school students, using a jigsaw-group mastery learning approach. The sample consisted of 73 students in the experimental group and 47 students who learned the topic in an individualized mastery learning approach. The study lasted 5 weeks. Pretests and posttests on academic achievement and affective outcomes were administered. Data were treated with an analysis of covariance. The results show that students of the experimental group achieved significantly higher on academic outcomes, both normative and objective scores. On the creative essay test, the differences in number of ideas and total essay score were not significant between the groups, although the mean scores for number of words were higher for the individualized mastery learning group. On the affective domain, jigsaw-group mastery learning students scored significantly higher on self-esteem, number of friends, and involvement in the classroom. No differences were found in cohesiveness, cooperation, competition, and attitudes toward the subject learned. The results are discussed through the evaluation and comparison of the two methods of instruction used in this study.The cooperative learning movement began in junior high schools as part of the desegregation process, aiming at facilitating positive ethnic relations and increasing academic achievement and social skills among diverse students (Aronson, Stephan, Sikes, Blaney, & Snapp, 1978; Sharan & Hertz-Lazarowitz, 1980; Slavin, 1980). However, elementary teachers quickly recognized the potential of cooperative methods, and such methods were adopted freely in elementary schools before becoming widespread on the junior and senior high level. It has only been during the past few years that application of cooperative learning has been studied extensively with these older students.Cooperative learning methods generally involve heterogeneous groups working together on tasks that are deliberately structured to

    Background : The Trends in International Mathematics and Science Study (TIMSS) assesses the quality of the teaching and learning of science and mathematics among Grades 4 and 8 students across participating countries. Purpose : This study explored the relationship between positive affect towards science and mathematics and achievement in science and mathematics among Malaysian and Singaporean Grade 8 students. Sample : In total, 4466 Malaysia students and 4599 Singaporean students from Grade 8 who participated in TIMSS 2007 were involved in this study. Design and method : Students' achievement scores on eight items in the survey instrument that were reported in TIMSS 2007 were used as the dependent variable in the analysis. Students' scores on four items in the TIMSS 2007 survey instrument pertaining to students' affect towards science and mathematics together with students' gender, language spoken at home and parental education were used as the independent variables. Results : Positive affect towards science and mathematics indicated statistically significant predictive effects on achievement in the two subjects for both Malaysian and Singaporean Grade 8 students. There were statistically significant predictive effects on mathematics achievement for the students' gender, language spoken at home and parental education for both Malaysian and Singaporean students, with R 2 = 0.18 and 0.21, respectively. However, only parental education showed statistically significant predictive effects on science achievement for both countries. For Singapore, language spoken at home also demonstrated statistically significant predictive effects on science achievement, whereas gender did not. For Malaysia, neither gender nor language spoken at home had statistically significant predictive effects on science achievement. Conclusions : It is important for educators to consider implementing self-concept enhancement intervention programmes by incorporating 'affect' components of academic

    2016-01-01

    Middle school has been documented as the period in which a drop in students' science interest and achievement occurs. This trend indicates a lack of motivation for learning science; however, little is known about how different aspects of motivation interact with student engagement and science learning outcomes. This study examines the relationships among motivational factors, engagement, and achievement in middle school science (grades 6-8). Data were obtained from middle school students in the United States (N = 2094). The theoretical relationships among motivational constructs, including self-efficacy, and three types of goal orientations (mastery, performance approach, and performance avoid) were tested. The results showed that motivation is best modeled as distinct intrinsic and extrinsic factors; lending evidence that external, performance based goal orientations factor separately from self-efficacy and an internal, mastery based goal orientation. Second, a model was tested to examine how engagement mediated the relationships between intrinsic and extrinsic motivational factors and science achievement. Engagement mediated the relationship between intrinsic motivation and science achievement, whereas extrinsic motivation had no relationship with engagement and science achievement. Implications for how classroom practice and educational policy emphasize different student motivations, and in turn, can support or hinder students' science learning are discussed.

    The current study examines the cognitive supports that underlie achievement in science by using a cultural historical framework (L. S. Vygotsky (1934/1986), Thought and Language, MIT Press, Cambridge, MA.) and the activity setting (AS) construct (R. G. Tharp & R. Gallimore (1988), Rousing minds to life: Teaching, learning and schooling in social context, Cambridge University Press, Cambridge, MA.) with its five features: personnel, motivations, scripts, task demands, and beliefs. Observations were made of the classrooms of seventh-grade science students, 32 of whom had participated in a prior achievement-related parent-child interaction or home study (P. R. Portes, M. F. Zady, & R. M. Dunham (1998), Journal of Genetic Psychology, 159, 163-178). The results of a quantitative analysis of classroom interaction showed two features of the AS: personnel and scripts. The qualitative field analysis generated four emergent phenomena related to the features of the AS that appeared to influence student opportunity for conceptual development. The emergent phenomenon were science activities, the building of learning, meaning in lessons, and the conflict over control. Lastly, the results of the two-part classroom study were compared to those of the home science AS of high and low achievers. Mismatches in the AS features in the science classroom may constrain the opportunity to learn. Educational implications are discussed.

  9. An Investigation of International Science Achievement Using the OECD's PISA 2006 Data Set

    Science.gov (United States)

    Milford, Todd

    School Effectiveness Research (SER) is concerned with efforts to better understand the effectiveness enhancing relationship between student and school variables and how these variables primarily influence academic achievement (Scheerens, 2004). However, one identified methodological shortcoming in SER is the absence of cross-cultural perspectives (Kyriakides, 2006). This is a concern as what may prove effective in one nation does not necessarily mean that it can be easily and seamlessly imported into another with the same results. This study looked at the relationships between science self-beliefs and academic achievement in science across all nations who participated in the Programme for International Student Assessment (PISA) in 2006. It further explored the variance accounted for by cultural, social and economic capital (the elements of the PISA socioeconomic status variable) for each country in PISA 2006 when predicting scientific literacy. Lastly, it used hierarchical linear modeling (HLM) to analyze data from PISA 2006 for nations experiencing high rates of immigration (i.e., Germany, Spain, Canada, the United States, Australia and New Zealand). The outcome measures used for these countries were achievement scores in science, mathematics and reading. The variables examined at the student level were science self-efficacy, science self-concept, immigrant status and socioeconomic status. The variables examined at the school level were student level aggregates of school proportion of immigrants and school socioeconomic status. In the correlation analysis between science literacy and either science self-concept of science self-efficacy, findings suggest that at the student level, students with both higher science self-concept and higher science self-efficacy tend to achieve higher academically. However, at the country level the relationship was negative between self-concept and academic achievement in science (i.e., countries with higher science self-concept tend

The aim of this study was to investigate the use of different types of academic achievement exams (evaluation methods by faculty of Ilam University of Medical Sciences. Instrument & Methods: In this descriptive and cross-sectional study, faculty members of Ilam University of Medical Sciences in the second semester of 2013-14 academic year (N=90 were studied by total counting. Data were gathered by a researcher made questionnaire by 29 questions that was assessing the application level of educational progress evaluation methods by faculty members. For data analysis, SPSS 16 software was used and descriptive and inferential statistics (Student T test and one-way ANOVA were performed. Findings: 76 of participants (93.8% placed a greater emphasis on the final exam. The most widely used methods for students' progress evaluation was multiple-choice questions (93.8% n=76, and low used assessment method was 360 degree evaluation (4.9% n=4. Comparing of mean scores of participants based on gender and academic degree, were not showed a significant differences, but comparison of the mean scores of participants based on faculty showed a significant difference (p<0.05. Conclusion: With respect to faculty member's emphasis on use and application of the final evaluation results and preferably less effort and common procedures, as well as less variety of evaluation methods of students' progress, paying attention to the new methods of educational achievement evaluation and implementation training courses for teachers is essential.

    This research investigated the role of implicit science beliefs in the gender gap in science aspirations and achievement, with the goal of testing identification with a female role model as a potential intervention strategy for increasing women's representation in science careers. At Time 1, women's implicit science stereotyping (i.e., associating men more than women with science) was linked to more negative (implicit and explicit) attitudes towards science and less identification with science. For men, stereotypes were either non-significantly or positively related to science attitudes and identification. Time 2 examined the influence of implicit and explicit science cognitions on students' science aspirations and achievement, and found that implicit stereotyping, attitudes, and identification were all unique predictors of science aspirations, but not achievement. Of more importance, Time 2 examined the influence of science role models, and found that identification with a role model of either gender reduced women's implicit science stereotyping and increased their positive attitudes toward science. Implications for decreasing the gender gap in advanced science achievement are discussed.

    Full Text Available Lack of preparation in science leads to high rates of attrition among science, technology, engineering, and mathematics (STEM majors, even among students who are highly oriented toward STEM. Using data for twenty-seven countries from the 2006 Program for International Student Assessment, we compare the United States with other industrialized countries in terms of fifteen-year-olds’ science achievement and their expectations to focus on STEM in the future. The United States trails most countries in the mean science achievement of the general student population and among students expecting to pursue STEM majors or careers. Lack of curricular standardization in the United States is related to this lower science achievement. Countries with higher curricular standardization exhibit higher average science achievement scores; science achievement and students’ future orientation toward science are also better aligned in these countries. We discuss the implications of these findings for American colleges and universities as they seek to reduce student attrition in STEM fields.

    Dimichino, Daniela C.

    This mixed-methods case study, influenced by aspects of grounded theory, aims to explore the relationships among a teacher's attitude toward inquiry-based middle school reform, their enactment of such a curriculum, and student interest and achievement in science. A solid theoretical basis was constructed from the literature on the benefits of inquiry-based science over traditional science education, the benefits of using constructivist learning techniques in the classroom, the importance of motivating teachers to change their teaching practices to be more constructive, and the importance of motivating and exciting students in order to boost achievement in science. Data was collected using qualitative documents such as teacher and student interviews, classroom observations, and curriculum development meetings, in addition to quantitative documents such as student science interest surveys and science skills tests. The qualitative analysis focused on examining teacher attitudes toward curricular reform efforts, and the enactments of three science teachers during the initial year of an inquiry-based middle school curriculum adoption using a fidelity of implementation tool constructed from themes that emerged from the data documents utilized in this study. In addition, both qualitative and quantitative tools were used to measure an increase or decrease in student interest and student achievement over the study year, and their resulting relationships to their teachers' attitudes and enactments of the curriculum. Results from data analysis revealed a positive relationship between the teachers' attitude toward curricular change and their fidelity of implementation to the developers' intentions, or curricular enactment. In addition, strong positive relationships were also discovered among teacher attitude, student interest, and student achievement. Variations in teacher enactment also related to variations in student interest and achievement, with considerable positive

    In order to create conditions for students' meaningful and rigorous intellectual engagement in science classrooms, it is critically important to help science teachers learn which strategies and approaches can be used best to develop students' scientific literacy. Better understanding how science teachers' instructional practices relate to student achievement can provide teachers with beneficial information about how to best engage their students in meaningful science learning. To address this need, this study examined the instructional practices that 99 secondary biology teachers used in their classrooms and employed regression to determine which instructional practices are predictive of students' science achievement. Results revealed that the secondary science teachers who had well-managed classroom environments and who provided opportunities for their students to engage in student-directed investigation-related experiences were more likely to have increased student outcomes, as determined by teachers' value-added measures. These findings suggest that attending to both generic and subject-specific aspects of science teachers' instructional practice is important for understanding the underlying mechanisms that result in more effective science instruction in secondary classrooms. Implications about the use of these observational measures within teacher evaluation systems are discussed.

  17. Achievement Emotions as Predictors of High School Science Success Among African-American and European American Students

    Science.gov (United States)

    Bowe, Marilyn Louise Simmons

    The literature includes few studies of the interrelations of achievement goals and achievement emotions with respect to minority students and science achievement. The objective of this study was to test the control-value theory (CVT) of achievement emotions to determine if the eight discrete achievement emotions would be predictive of test scores on the High School Graduation Test (GHSGT)-Science for African-American compared to European-American science students. Convenience cluster sampling was employed to select 160 students who were all juniors in the same public high school at the time that they took the GHSGT-Science. The central research question for this study aimed to uncover whether any of the eight achievement emotions identified in CVT would contribute significantly to the predictability of science achievement as measured by GHSGT-Science scores. Data were collected using a nonexperimental, cross sectional design survey. Data were analyzed using a hierarchal, forced entry, multiple regression analysis. Key results indicated that the eight achievement emotions were predictive of GHSGT-Science score outcomes. Positive social change at the individual level could reflect a boost in confidence for African American science students and help decrease the achievement gap in science, technology, engineering, and mathematics (STEM) endeavors between European Americans and African-American students. Educators may consider the importance of achievement emotions in science outcomes by including social emotional learning (SEL) as a part of the regular science curriculum. Future researchers should repeat the study in a school district where the population is available to support the desired cluster sample of equal parts European Americans to African Americans and male to female students.

    Askew Cain, Peggy

    The problem was middle-grade students with specific learning disabilities (SWDs) in reading comprehension perform less well than their peers on standardized assessments. The purpose of this quantitative comparative study was to examine the effect of electronic concept maps on reading comprehension of eighth grade students with SWD reading comprehension in a Hawaii middle school Grade 8 science class on the island of Oahu. The target population consisted of Grade 8 science students for school year 2015-2016. The sampling method was a purposeful sampling with a final sample size of 338 grade 8 science students. De-identified archival records of grade 8 Hawaii standardized science test scores were analyzed using a one way analysis of variance (ANOVA) in SPSS. The finding for hypothesis 1 indicated a significant difference in student achievement between SWDs and SWODs as measured by Hawaii State Assessment (HSA) in science scores (p reading comprehension. Recommendations for practice were for educational leadership and noted: (a) teachers should practice using concept maps with SWDs as a specific reading strategy to support reading comprehension in science classes, (b) involve a strong focus on vocabulary building and concept building during concept map construction because the construction of concept maps sometimes requires frontloading of vocabulary, and (c) model for teachers how concept maps are created and to explain their educational purpose as a tool for learning. Recommendations for future research were to conduct (a) a quantitative comparative study between groups for academic achievement of subtests mean scores of SWDs and SWODs in physical science, earth science, and space science, and (b) a quantitative correlation study to examine relationships and predictive values for academic achievement of SWDs and concept map integration on standardized science assessments.

    2010-07-01

    This study examined the effects of individual student factors and classroom factors on elementary science achievement within and across five countries. The student-level factors included gender, self-confidence in science and home resources. The classroom-level factors included teacher characteristics, instructional variables and classroom composition. Results for the USA and four other countries, Singapore, Japan, Australia and Scotland, were reported. Multilevel effects were examined through Hierarchical Linear Modelling, using the Trends in International Mathematics and Science Study 2003 fourth grade dataset. Overall, the results showed that selected student background characteristics were consistently related to elementary science achievement in countries investigated. At the student level, higher levels of home resources and self-confidence and at the classroom level, higher levels of class mean home resources yielded higher science scores on the TIMSS 2003. In general, teacher and instructional variables were minimally related to science achievement. There was evidence of positive effects of teacher support in the USA and Singapore. The emphasis on science inquiry was positively related to science achievement in Singapore and negatively related in the USA and Australia. Recommendations for practice and policy were discussed.

  1. Influence of science and technology magnet middle schools on students' motivation and achievement in science

    Science.gov (United States)

    Allen, David

    Some informal discussions among educators regarding motivation of students and academic performance have included the topic of magnet schools. The premise is that a focused theme, such as an aspect of science, positively affects student motivation and academic achievement. However, there is limited research involving magnet schools and their influence on student motivation and academic performance. This study provides empirical data for the discussion about magnet schools influence on motivation and academic ability. This study utilized path analysis in a structural equation modeling framework to simultaneously investigate the relationships between demographic exogenous independent variables, the independent variable of attending a science or technology magnet middle school, and the dependent variables of motivation to learn science and academic achievement in science. Due to the categorical nature of the variables, Bayesian statistical analysis was used to calculate the path coefficients and the standardized effects for each relationship in the model. The coefficients of determination were calculated to determine the amount of variance each path explained. Only five of 21 paths had statistical significance. Only one of the five statistically significant paths (Attended Magnet School to Motivation to Learn Science) explained a noteworthy amount (45.8%) of the variance.

    The purpose of this research was to investigate the relationship between eighth-grade students' maths-related self-concepts and their achievements in the Trends in International Mathematics and Science Study (TIMSS) 2007. The students' maths self-concept was compared with other variables, namely their mothers' education, their fathers' education and the amount of books held in the students' households. To investigate the potential role of culture, a comparison between American and Japanese students' scores was also included. The findings demonstrated that students' maths self-concept was positively associated with their achievement both in the United States and Japan, but Japanese students, while having higher achievement, had a lower maths self-concept than American students. Maternal education, paternal education and the number of books at home were also found to be positively related to achievement. Examining standardised coefficients, the study confirmed a strong interaction between maths self-concept and country, as well as a positive connection between maths self-concept as such (irrespective of the country) with maths achievement.

  3. Understanding the factors that influence high science achievers' academic choices and intent to pursue or opt out of the hard sciences

    Science.gov (United States)

    Quihuis, Gisell

    Drawing on Eccles and her colleagues' Expectancy-Value model of academic behavior and choice, this dissertation study set out to serve three purposes: (1) to understand how high achieving high school students who aspire to science college degrees compare, in terms of motivational beliefs and social experiences, with other high achievers who do not aspire to science college degrees; (2) to understand why some high school students who excel in the hard sciences are unsure about pursuing a science degree in college; and (3) to examine whether gender differences in motivational beliefs and social experiences found in previous research on math (see Eccles 1984) exist for science among high achieving high school students. Survey and interview data showed that gender differences previously found in Eccles' research on math exist for science among a select group of high achieving high school students. Yet, these gender differences did not explain students' aspirations for science. Motivation, classroom perceptions, science engagement, as well as other science-related experiences at home and school, including parent and teacher influences, were also important factors associated with students' aspirations for science. Results and implications for this study are encouraging because they suggest that both parents and educators can help more high achievers become interested in science. Parents can expose their children, male and female alike, to science at home early on in their childhood and teachers can help students sustain and further develop an interest in science at school. In this manner, both parents and teachers can work together as a team to encourage more high achievers to aspire to science degrees in their future. Lastly, it is important to note that this study found Eccles' model of motivation and choice helpful in understanding not only gender differences in math and the hard sciences, but also aspiration differences that cut across gender among students

    Ellis, Valeisha Michelle

    The purpose of this study was to examine whether possible relationships might exist between the quality of reform-based science instruction and science and reading achievement in second grade. The study also examined separately possible interactions between quality of instruction and gender and race. The study involved an analysis of data previously collected in a larger one-group pre/post test study of a science instructional intervention (ISI Science) (Connor et al., 2010). In the original study, six teachers and two graduate assistants taught two science units designed based upon constructivist principles and reform-based practices. Using the 5-E Learning Cycle (Bybee, 1997), reading and science were integrated into each lesson. Videotapes were made of all lessons and science and reading achievement data were collected. For the current study, dependent achievement variables were science achievement measured by the Iowa Science Test; reading comprehension, by the Woodcock Passage Comprehension; and vocabulary, by the Iowa Vocabulary. Pre- and post-tests scores on the dependent measures were available for 96 children from the original study. Quality of instruction was measured using the Reformed Teaching Observation Protocol (RTOP) (Sawanda & Piburn, 2000). Videotapes of 24 science lessons from the larger study were analyzed using the RTOP. Reliability of ratings for the RTOP in the study was determined to be .96. No significant results were found for relations between instructional quality (RTOP) and any of the achievement variables although significant pre to post increases on all three measures were observed. No differences by race or gender were found. This latter finding was noteworthy given the research in science identifying both gender and race differences in science achievement. Recommendations for future research and teacher education are discussed.

  8. Academic attainment and the high school science experiences among high-achieving African American males

    Trice, Rodney Nathaniel

    This study examines the educational experiences of high achieving African American males. More specifically, it analyzes the influences on their successful navigation through high school science. Through a series of interviews, observations, questionnaires, science portfolios, and review of existing data the researcher attempted to obtain a deeper understanding of high achieving African American males and their limitations to academic attainment and high school science experiences. The investigation is limited to ten high achieving African American male science students at Woodcrest High School. Woodcrest is situated at the cross section of a suburban and rural community located in the southeastern section of the United States. Although this investigation involves African American males, all of whom are successful in school, its findings should not be generalized to this nor any other group of students. The research question that guided this study is: What are the limitations to academic attainment and the high school science experiences of high achieving African American males? The student participants expose how suspension and expulsion, special education placement, academic tracking, science instruction, and teacher expectation influence academic achievement. The role parents play, student self-concept, peer relationships, and student learning styles are also analyzed. The anthology of data rendered three overarching themes: (1) unequal access to education, (2) maintenance of unfair educational structures, and (3) authentic characterizations of African American males. Often the policies and practices set in place by school officials aid in creating hurdles to academic achievement. These policies and practices are often formed without meaningful consideration of the unintended consequences that may affect different student populations, particularly the most vulnerable. The findings from this study expose that high achieving African American males face major

  9. Cognitive abilities and motivational processes in high school students' science achievement and engagement

    Science.gov (United States)

    Lau, Shun

    The dissertation presents two analytic approaches, a variable-centered and person-centered approach, to investigating holistic patterns of the cognitive, motivational, and affective correlates of science achievement and engagement in a sample of 491 10th and 11th grade high-school students. Building on Snow's (1989) idea of two pathways to achievement outcomes, Study 1 adopted a variable-centered approach to examining how cognitive and motivational factors associated with the performance and commitment pathways, respectively, contributed to the prediction of achievement outcomes in science. Results of hierarchical regression analyses showed that (a) students' cognitive abilities were the strongest predictors of their performance in science as measured by standardized test scores; (b) motivational processes enhanced the predictive validity for science test scores and grades beyond the variance accounted for by ability and demography; (c) motivational processes were the strongest predictors of students' commitment to science in the form of situational engagement and anticipated choices of science-related college majors and careers; and (d) competence beliefs served as a point of contact between the performance and commitment pathways. These results are consistent with Snow's (1989) conjecture that both performance and commitment pathway-related factors are necessary for understanding the full range of person-level inputs to achievement outcomes. Study 2 adopted a person-centered approach to examining holistic organizations of psychological factors within individuals and their relations to science achievement and engagement. Four types of students characterized by unique configurations of cognitive, motivational, and affective attributes were identified in both the male and female subsamples using inverse factor analysis. Type membership was found to distinguish students in various indicators of science achievement and engagement. Two of the four types were also found

    Muller, Patricia Ann

    The purpose of this study was to gain a more complete understanding of the differences in science, mathematics and engineering education among racial-ethnic and gender subgroups by exploring factors related to precollege science achievement growth rates. Using Hierarchical Linear Modeling (HLM) and multi-wave, longitudinal data from the first three waves of the National Education Longitudinal Study of 1988--1994 (NELS:88/94), this study examined precollege science achievement growth rates during the 8th to 10th grade period and the 10th to 12th grade period for African American males, African American females, Latino males, Latina females, Asian American males, Asian American females, White males and White females. For the 8th--10th grade period, previous grades were significantly and positively related to science achievement growth for all subgroups; and socio-economic status and high school program were significantly and positively related to science achievement growth for all subgroups except one (Latino males, and Asian American males respectively). For the 10th--12th grade period, the quantity of science courses completed (science units) was the only variable that was statistically significant for more than one racial-ethnic by gender subgroup. Science units taken were significantly and positively related to 10 th--12th grade growth rates for all racial-ethnic by gender subgroups except Latino males. Locus-of-control was the only cognitive or psychosocial factor included from Eccles, Adler, Futterman, Goff, Kaczala, Meece and Midgley's (1983) theoretical framework for achievement behaviors that appeared to exhibit any pattern across race-ethnicities. Locus-of-control was positively related to 8th--10 th grade science achievement growth for females across all racial-ethnic subgroups, as well as for African American males. However, for both the 8 th--10th grade and 10th--12 th grade periods, there was no consistency across racial-ethnic or gender subgroups in

    Zelmanowicz, Marc

    Purpose The use of technology in the science classroom has been a major part of the initiative toward increasing student attitude and achievement in Science, Technology, Education and Math [STEM] education in the United States. The purpose of this study was to determine the extent to which the use of probeware in a high school science living environment classroom impacts student attitude towards science and/or student achievement on standards-based assessments. This study sought to answer the following quantitative questions with a qualitative component: To what extent does the use of probeware in a high school level living environment course influence student attitudes toward science compared to students who are not using probeware? What is the impact, if any, on student achievement in a living environment course, as measured by New York State Living Environment Regents [NYSLER] exam grades, between students who use probeware and students who do not? Is there a significant difference between the two groups with regard to achieving mastery on the NYSLER exam? Sample The participants in the study were Living Environment students of a suburban high school outside of New York City. Methods The quasiexperimental study examined the effects of the replacement of traditional scientific equipment with probeware on student attitude and achievement in a living environment classroom. Student attitude was measured by the modified Attitude Toward Science Inventory [mATSI] and student achievement was measured by the New York State Living Environment Regents [NSLER] Exam. Descriptive statistics, ANCOVA and hierarchical regression analysis were conducted to answer the research questions in this study. A qualitative component was included to enhance the understanding of the quantitative analysis. Major Findings Through this study, results demonstrated a statistically significant impact of probeware on student attitude, but did not show a statistically significant impact of

    Background. There are attempts to integrate learning environment research with motivation and self-regulation research that considers social context influences an individual's motivation, self-regulation and, in turn, academic performance. Purpose. This study explored the relationships among constructivist learning environment perception variables (personal relevance, uncertainty, shared control, critical voice, student negotiation), motivational beliefs (self-efficacy, intrinsic interest, goal orientation), self-regulation, and science achievement. Sample. The sample for this study comprised 802 Grade 8 students from 14 public middle schools in a district of Ankara in Turkey. Design and methods. Students were administered 4 instruments: Constructivist Learning Environment Survey, Goal Achievement Questionnaire, Motivated Strategies for Learning Questionnaire, and Science Achievement Test. LISREL 8.7 program with SIMPLIS programming language was used to test the conceptual model. Providing appropriate fit indices for the proposed model, the standardized path coefficients for direct effects were examined. Results. At least one dimension of the constructivist learning environment was associated with students' intrinsic interest, goal orientation, self-efficacy, self-regulation, and science achievement. Self-efficacy emerged as the strongest predictor of both mastery and performance avoidance goals rather than the approach goals. Intrinsic value was found to be significantly linked to science achievement through its effect on self-regulation. The relationships between self-efficacy and self-regulation and between goal orientation and science achievement were not significant. Conclusion. In a classroom environment supporting student autonomy and control, students tend to develop higher interest in tasks, use more self-regulatory strategies, and demonstrate higher academic performance. Science teachers are highly recommended to consider these findings when designing

    Salame, Hania Moussa

    The purpose of the current study was to examine the effects of adapting the instructional congruence model on the English Language Learners' (ELL) attitudes and achievement in science. Changes in teacher's views and practices were documented. The mixed-method approach was adapted. Data sources were the "Attitude Towards Science" survey, VNOS-C questionnaire, Luykx and Lee (2007) observational instrument, Gee (1997) discussion categories, video recordings, and pre- and post-tests. A science teacher and a class of 24 ELL female students in a charter school participated in this research. The results of this study indicated that student achievement increased significantly and students' attitudes improved in all contexts. At the conclusion of the study, all teacher's views on NOS were reported to be informed, teacher's practices were rated higher, and different classroom interactions increased significantly. The instructional congruence model in science education has been successful in reaching different learners, improving students' attitudes and achievement in science and enhancing teacher's views and practices. This model has significant potential for meeting the challenging goals of reformed science education.

    Mokshein, Siti Eshah

    The importance of science and technology in the global economy has led to growing emphasis on math and science achievement all over the world. In this study, I seek to identify variables at the student-level and school-level that account for the variation in science achievement of the eighth graders in Malaysia. Using the Third International Math and Science Study (TIMSS) 1999 for Malaysia, a series of HLM analysis was performed. Results indicate that (1) variation in overall science achievement is greater between schools than within schools; (2) both the selected student-level and school-level factors are Important in explaining the variation in the eight graders' achievement In science; (3) the selected student-level variables explain about 13% of the variation in students' achievement within schools, but as an aggregate, they account for a much larger proportion of the between-school variance; (4) the selected school-level variables account for about 55% of the variation between schools; (5) within schools, the effects of self-concept In science, awareness of the social implications of science, gender, and home educational resources are significantly related to achievement; (6) the effects of self-concept in science and awareness of social implications of science are significant even after controlling for the effects of SES; (7) between schools, the effects of the mean of home educational resources, mean of parents' education, mean of awareness of the social implications of science, and emphasis on conducting experiments are significantly related to achievement; (8) the effects of SES variables explain about 50% of the variation in the school means achievement; and (9) the effects of emphasis on conducting experiments on achievement are significant even after controlling for the effects of SES. Since it is hard to change the society, it is recommended that efforts to Improve science achievement be focused more at the school-level, concentrating on variables that

    Ulkins, David S.

    Studies indicate a gap in science achievement and positive attitudes towards science between gifted male and female students with females performing less than the males. This study investigated the impact of a single-gender classroom environment as opposed to a mixed-gender classroom, on motivation, locus of control, self-concept, and science achievement of middle school gifted girls. The Motivated Strategies for Learning Questionnaire (MSLQ), Review of Personal Effectiveness with Locus of Control (ROPELOC), Test of Science Related Attitudes (TOSRA), and Stanford Achievement Test 10th Edition, were used to measure the dependent variables respectively. The independent-measure t test was used to compare the differences between girls in a single-gender classroom with the ones in a mixed-gender classroom. A significant difference in the external locus of control resulted for girls in the single gender classroom. However, there were no significant differences found in science achievement, motivation, and the attitudes toward science between the two groups. The implication is that a single-gender learning environment and the use of differentiated teaching strategies can help lessen the negative effects of societal stereotypes in today's classrooms. These, along with being cognizant of the differences in learning styles of girls and their male counterparts, will result in a greater level of success for gifted females in the area of science education.

    Full Text Available In the Digital Age teachers have fallen far behind the technical skills of their "digital native" students. The implementation of technology as a tool for classroom communication is foreign for most teachers, but highly preferred by students. While teenagers are using Facebook, Twitter, and other social networks to communicate, teachers continue to respond through face-to-face conversations, telephone calls, and email messaging. Twitter, a platform for short message service text, is an online social network site that allows users to send and receive messages using 140 characters or less called Tweets. To analyze the relationship of the teacher's use of Twitter with student academic achievement, a correlation study conducted by Bess collected data from two matched samples of eighth grade science students: one utilizing Twitter and one not utilizing Twitter to reinforce classroom instruction. Two tests matching the science standards were given to both samples of students. The results of the tests were used as primary data. The findings suggested a positive correlation between the use of Twitter and student performance on the standardized tests. Implications for this study indicate that young teenagers may prefer Twitter as a mode of communication with their teacher, resulting in higher academic achievement in a middle school science class.

    Canadian students experience many different assessments throughout their schooling (O'Connor 2011). There are many benefits to using a variety of assessment types, item formats, and science-based performance tasks in the classroom to measure the many dimensions of science education. Although using a variety of assessments is beneficial, it is unclear exactly what types, format, and tasks are used in Canadian science classrooms. Additionally, since assessments are often administered to help improve student learning, this study identified assessments that may improve student learning as measured using achievement scores on a standardized test. Secondary analyses of the students' and teachers' responses to the questionnaire items asked in the Pan-Canadian Assessment Program were performed. The results of the hierarchical linear modeling analyses indicated that both students and teachers identified teacher-developed classroom tests or quizzes as the most common types of assessments used. Although this ranking was similar across the country, statistically significant differences in terms of the assessments that are used in science classrooms among the provinces were also identified. The investigation of which assessment best predicted student achievement scores indicated that minds-on science performance-based tasks significantly explained 4.21% of the variance in student scores. However, mixed results were observed between the student and teacher responses towards tasks that required students to choose their own investigation and design their own experience or investigation. Additionally, teachers that indicated that they conducted more demonstrations of an experiment or investigation resulted in students with lower scores.

    In this study, the authors introduced a multivariate multilevel model to estimate the consistency among students and schools in the rates of growth between mathematics and science achievement during the entire middle and high school years with data from the Longitudinal Study of American Youth (LSAY). There was no evident consistency in the rates of growth between mathematics and science achievement among students, and this inconsistency was not much influenced by student characteristics and school characteristics. However, there was evident consistency in the average rates of growth between mathematics and science achievement among schools, and this consistency was influenced by student characteristics and school characteristics. Major school-level variables associated with parental involvement did not show any significant impacts on consistency among either students or schools. Results call for educational policies that promote collaboration between mathematics and science departments or teachers.

    2017-06-01

    This study, drawing on data from the third cycle of the Program for International Student Assessment (PISA) and employing three-level hierarchical linear modeling (HLM) as an analytic strategy, examined the relations of inquiry-based science teaching to science achievement and dispositions toward science among 170,474 15-year-old students from 4780 schools in 54 countries across the globe. The results of the HLM analyses, after accounting for student-, school-, and country-level demographic characteristics and students' dispositions toward science, revealed that inquiry-based science teaching was significantly negatively related to science achievement. In contrast, inquiry-based science teaching was significantly positively associated with dispositions toward science, such as interest in and enjoyment of science learning, instrumental and future-oriented science motivation, and science self-concept and self-efficacy. Implications of the findings for policy and practice are discussed.

    Larry, Triaka A.

    The need for more diversity in STEM-related careers and college majors is urgent. Self-efficacy and student-teacher relationships are factors that have been linked to influencing students’ pursuit of subject-specific careers and academic achievement. The impact of self-efficacy and student perceptions of teacher interpersonal behaviors on student achievement have been extensively researched in the areas of Mathematics and English, however, most studies using science achievement, as a criterion variable, were conducted using non-diverse, White upper middle class to affluent participants. In order to determine the strength of relationships between perceived science self-efficacy, and student perceptions of teacher interpersonal behaviors as factors that influence science achievement (science GPA), the Science Self-Efficacy Questionnaire (SSEQ) and Questionnaire on Teacher Interactions (QTI) were administered to twelfth grade students enrolled at a highly diverse urban Title I high school, while controlling for demographics, defined as gender, ethnicity, and minority status. Using a hierarchical multiple linear regression analysis, results demonstrated that the predictor variables (i.e., gender, ethnicity, minority status, science self-efficacy, and teacher interpersonal behaviors) accounted for 20.8% of the variance in science GPAs. Science self-efficacy made the strongest unique contribution to explaining science GPA, while minority status and gender were found to be statistically significant contributors to the full model as well. Ethnicity and teacher interpersonal behaviors did not make a statistically significant contribution to the variance in science GPA, and accounted for ≤ 1% of the variance. Implications and recommendations for future research are subsequently given.

    Mebane, Joyce Graham

    The purpose of this study was to examine the perceptions of West High School constituents (students, parents, teachers, administrators, and guidance counselors) about the readiness and interest of African American students at West High School to take Advanced Placement (AP) and International Baccalaureate (IB) science courses as a strategy for closing the achievement gap. This case study utilized individual interviews and questionnaires for data collection. The participants were selected biology students and their parents, teachers, administrators, and guidance counselors at West High School. The results of the study indicated that just over half the students and teachers, most parents, and all guidance counselors thought African American students were prepared to take AP science courses. Only one of the three administrators thought the students were prepared to take AP science courses. Between one-half and two-thirds of the students, parents, teachers, and administrators thought students were interested in taking an AP science course. Only two of the guidance counselors thought there was interest among the African American students in taking AP science courses. The general consensus among the constituents about the readiness and interest of African American students at West High School to take IB science courses was that it is too early in the process to really make definitive statements. West is a prospective IB school and the program is new and not yet in place. Educators at the West High School community must find reasons to expect each student to succeed. Lower expectations often translate into lower academic demands and less rigor in courses. Lower academic demands and less rigor in courses translate into less than adequate performance by students. When teachers and administrators maintain high expectations, they encourage students to aim high rather than slide by with mediocre effort (Lumsden, 1997). As a result of the study, the following suggestions should

  7. The Effect of Executive Function on Science Achievement Among Normally Developing 10-Year Olds

    Science.gov (United States)

    Lederman, Sheri G.

    Executive function (EF) is an umbrella term used to identify a set of discrete but interrelated cognitive abilities that enable individuals to engage in goal-directed, future-oriented action in response to a novel context. Developmental studies indicate that EF is predictive of reading and math achievement in middle childhood. The purpose of this study was to identify the association between EF and science achievement among normally developing 10 year olds. A sample of fifth grade students from a Northeastern suburban community participated in tests of EF, science, and intelligence. Consistent with adult models of EF, principal components analysis identified a three-factor model of EF organization in middle childhood, including cognitive flexibility, working memory, and inhibition. Multiple regression analyses revealed that executive function processes of cognitive flexibility, working memory, and inhibition were all predictive of science performance. Post hoc analyses revealed that high-performing science students differed significantly from low-performing students in both cognitive flexibility and working memory. These findings suggest that complex academic demands specific to science achievement rely on the emergence and maturation of EF components.

  8. The effects of hands-on-science instruction on the science achievement of middle school students

    Science.gov (United States)

    Wiggins, Felita

    Student achievement in the Twenty First Century demands a new rigor in student science knowledge, since advances in science and technology require students to think and act like scientists. As a result, students must acquire proficient levels of knowledge and skills to support a knowledge base that is expanding exponentially with new scientific advances. This study examined the effects of hands-on-science instruction on the science achievement of middle school students. More specifically, this study was concerned with the influence of hands-on science instruction versus traditional science instruction on the science test scores of middle school students. The subjects in this study were one hundred and twenty sixth-grade students in six classes. Instruction involved lecture/discussion and hands-on activities carried out for a three week period. Specifically, the study ascertained the influence of the variables gender, ethnicity, and socioeconomic status on the science test scores of middle school students. Additionally, this study assessed the effect of the variables gender, ethnicity, and socioeconomic status on the attitudes of sixth grade students toward science. The two instruments used to collect data for this study were the Prentice Hall unit ecosystem test and the Scientific Work Experience Programs for Teachers Study (SWEPT) student's attitude survey. Moreover, the data for the study was treated using the One-Way Analysis of Covariance and the One-Way Analysis of Variance. The following findings were made based on the results: (1) A statistically significant difference existed in the science performance of middle school students exposed to hands-on science instruction. These students had significantly higher scores than the science performance of middle school students exposed to traditional instruction. (2) A statistically significant difference did not exist between the science scores of male and female middle school students. (3) A statistically

  9. Relationship of sex, achievement, and science self-concept to the science career preferences of black students

    Jacobowitz, Tina

    Science career preferences of junior high school-aged students, while not stable predictors of ultimate career choice, do serve to direct and maintain individuals along the paths to careers in science. In this study, factors relevant to science career preferences of black eighth grade students were investigated. This issue is of particular import to blacks since they are severely underrepresented in the scientific fields. The sample consisted of 113 males and 148 females in an inner city junior high school. The Science Career Preference Scale, the Peabody Picture Vocabulary Test, and the Self-Concept of Ability Scale (Form B-Science) were administered. Mathematics and science grades were obtained from class rating sheets. Treatment of the data involved multiple regression analysis according to a hierarchical model. Results showed that of all the independent variables, sex was the strongest predictor of science career preferences, accounting for 25% of the criterion variance. The findings suggest that early adolescent science career preferences are related more to interests that are consonant with sex-role considerations than realistic assessment of mathematics or science achievement.

    Topping, Kecia C.

    This dissertation examined factors that affected the science achievement of African American females in suburban middle schools. The research literature informed that African American females are facing the barriers of race, gender, socioeconomic status, and cultural learning style preferences. Nationally used measurements of science achievement such as the Standardized Achievement Test, Tenth edition (SAT-10), National Assessment for Educational Progress, and National Center for Educational Statistics showed that African American females are continuing to falter in the areas of science when compared to other ethnic groups. This study used a transformative sequential explanatory mixed methods design. In the first, quantitative, phase, the relationships among the dependent variables, science subscale SAT-10 NCE scores, yearly averages, and the independent variables, attitude toward science scores obtained from the Modified Fennema-Sherman Attitudes toward Science Scale, socioeconomics, and caregiver status were tested. The participants were 150 African American females in grades 6 through 8 in four suburban middle schools located in the Southeastern United States. The results showed a positive, significant linear relationship between the females' attitude and their science subscale SAT-10 NCE scores and a positive, significant linear relationship between the females' attitudes and their yearly averages in science. The results also confirmed that attitude was a significant predictor of science subscale SAT-10 NCE scores for these females and that attitude and socioeconomics were significant predictors of the females' yearly averages in science. In the second, qualitative, phase, nine females purposefully selected from those who had high and low attitude towards science scores on the scale in the quantitative phase were interviewed. The themes that emerged revealed seven additional factors that impacted the females' science achievement. They were usefulness of science

    While the achievement gap in science exists in the US, research associated with our investigation reveals some high school science programs serving diverse student bodies are successfully closing the gap. Using a mixed methods approach, we identified and investigated ten high schools in a large Southwestern state that fit the definition of "highly successful, highly diverse". By conducting interviews with science liaisons associated with each school and reviewing the literature, we developed a rubric identifying specific characteristics associated with successful science programs. These characteristics and practices included setting high expectations for students, providing extensive teacher support for student learning, and utilizing student-centered pedagogy. We used the rubric to assess the successful high school science programs and compare them to other high school science programs in the state (i.e., less successful and less diverse high school science programs). Highly successful, highly diverse schools were very different in their approach to science education when compared to the other programs. The findings from this study will help schools with diverse students to strengthen hiring practices, enhance teacher support mechanisms, and develop student-focused strategies in the classroom that increase science achievement.

  14. Using hierarchical linear growth models to evaluate protective mechanisms that mediate science achievement

    Science.gov (United States)

    von Secker, Clare Elaine

    The study of students at risk is a major topic of science education policy and discussion. Much research has focused on describing conditions and problems associated with the statistical risk of low science achievement among individuals who are members of groups characterized by problems such as poverty and social disadvantage. But outcomes attributed to these factors do not explain the nature and extent of mechanisms that account for differences in performance among individuals at risk. There is ample theoretical and empirical evidence that demographic differences should be conceptualized as social contexts, or collections of variables, that alter the psychological significance and social demands of life events, and affect subsequent relationships between risk and resilience. The hierarchical linear growth models used in this dissertation provide greater specification of the role of social context and the protective effects of attitude, expectations, parenting practices, peer influences, and learning opportunities on science achievement. While the individual influences of these protective factors on science achievement were small, their cumulative effect was substantial. Meta-analysis conducted on the effects associated with psychological and environmental processes that mediate risk mechanisms in sixteen social contexts revealed twenty-two significant differences between groups of students. Positive attitudes, high expectations, and more intense science course-taking had positive effects on achievement of all students, although these factors were not equally protective in all social contexts. In general, effects associated with authoritative parenting and peer influences were negative, regardless of social context. An evaluation comparing the performance and stability of hierarchical linear growth models with traditional repeated measures models is included as well.

    Harvey, Robert Christopher

    The purpose of this study was to determine the effects of two conceptually based instructional strategies on science achievement and attitudes of community college biological science students. The sample consisted of 277 students enrolled in General Biology 1, Microbiology, and Human Anatomy and Physiology 1. Control students were comprised of intact classes from the 2005 Spring semester; treatment students from the 2005 Fall semester were randomly assigned to one of two groups within each course: written narrative (WN) and illustration (IL). WN students prepared in-class written narratives related to cell theory and metabolism, which were taught in all three courses. IL students prepared in-class illustrations of the same concepts. Control students received traditional lecture/lab during the entire class period and neither wrote in-class descriptions nor prepared in-class illustrations of the targeted concepts. All groups were equivalent on age, gender, ethnicity, GPA, and number of college credits earned and were blinded to the study. All interventions occurred in class and no group received more attention or time to complete assignments. A multivariate analysis of covariance (MANCOVA) via multiple regression was the primary statistical strategy used to test the study's hypotheses. The model was valid and statistically significant. Independent follow-up univariate analyses relative to each dependent measure found that no research factor had a significant effect on attitude, but that course-teacher, group membership, and student academic characteristics had a significant effect (p < .05) on achievement: (1) Biology students scored significantly lower in achievement than A&P students; (2) Microbiology students scored significantly higher in achievement than Biology students; (3) Written Narrative students scored significantly higher in achievement than Control students; and (4) GPA had a significant effect on achievement. In addition, given p < .08: (1

    Affhalter, Maria Geralyn

    An action research project using science inquiry labs and cooperative learning groups examined the effects of same-gender and co-educational classrooms on science achievement and teacher-assigned or self-selected group roles on students' role preferences. Fifty-nine seventh grade students from a small rural school district participated in two inquiry labs in co-educational classrooms or in an all-female classroom, as determined by parents at the beginning of the academic year. Students were assigned to the same cooperative groups for the duration of the study. Pretests and posttests were administered for each inquiry-based science lab. Posttest assessments included questions for student reflection on role assignment and role preference. Instruction did not vary and a female science teacher taught all class sections. The same-gender classroom and co-ed classrooms produced similar science achievement scores on posttests. Students' cooperative group roles, whether teacher-assigned or self-selected, produced similar science achievement scores on posttests. Male and female students shared equally in favorable and unfavorable reactions to their group roles during the science inquiry labs. Reflections on the selection of the leader role revealed a need for females in co-ed groups to be "in charge". When reflecting on her favorite role of leader, one female student in a co-ed group stated, "I like to have people actually listen to me".

    We present the results of a study conducted by the National Academies of Sciences, Engineering, and Medicine. The study focused on the scientific potential and technological promise of CubeSats. We will first review the growth of the CubeSat platform from an education-focused technology toward a platform of importance for technology development, science, and commercial use, both in the United States and internationally. The use has especially exploded in recent years. For example, of the over 400 CubeSats launched since 2000, more than 80% of all science-focused ones have been launched just in the past four years. Similarly, more than 80% of peer-reviewed papers describing new science based on CubeSat data have been published in the past five years.We will then assess the technological and science promise of CubeSats across space science disciplines, and discuss a subset of priority science goals that can be achieved given the current state of CubeSat capabilities. Many of these goals address targeted science, often in coordination with other spacecraft, or by using sacrificial or high-risk orbits that lead to the demise of the satellite after critical data have been collected. Other goals relate to the use of CubeSats as constellations or swarms, deploying tens to hundreds of CubeSats that function as one distributed array of measurements.Finally, we will summarize our conclusions and recommendations from this study; especially those focused on nearterm investment that could improve the capabilities of CubeSats toward increased science and technological return and enable the science communities’ use of CubeSats.

    Martin, Lynn A.

    The purpose of this study was to examine the relationship between teachers' self-reported preparedness for teaching science content and their instructional practices to the science achievement of eighth grade science students in the United States as demonstrated by TIMSS 2007. Six hundred eighty-seven eighth grade science teachers in the United States representing 7,377 students responded to the TIMSS 2007 questionnaire about their instructional preparedness and their instructional practices. Quantitative data were reported. Through correlation analysis, the researcher found statistically significant positive relationships emerge between eighth grade science teachers' main area of study and their self-reported beliefs about their preparedness to teach that same content area. Another correlation analysis found a statistically significant negative relationship existed between teachers' self-reported use of inquiry-based instruction and preparedness to teach chemistry, physics and earth science. Another correlation analysis discovered a statistically significant positive relationship existed between physics preparedness and student science achievement. Finally, a correlation analysis found a statistically significant positive relationship existed between science teachers' self-reported implementation of inquiry-based instructional practices and student achievement. The data findings support the conclusion that teachers who have feelings of preparedness to teach science content and implement more inquiry-based instruction and less didactic instruction produce high achieving science students. As science teachers obtain the appropriate knowledge in science content and pedagogy, science teachers will feel prepared and will implement inquiry-based instruction in science classrooms.

  2. The Effect of Thinking Maps on Fifth Grade Science Achievement

    Science.gov (United States)

    Hudson, Darlene

    Informational texts, such as those found in science education, have historically been reserved for secondary students. With the increased emphasis on elementary students' academic accountability, these high impact instructional strategies must also be utilized to support subject matter comprehension for younger students. This causal-comparative study, grounded in cognitive learning theory, sought to discover if 2 years of implementation and use of Thinking Maps, a visual tool program, had an effect on student achievement in elementary science as measured by Georgia's statewide assessment known as the Criterion-Referenced Competency Test (CRCT). Achievement data of 2 groups that received Thinking Maps instruction for 2 years was compared to 1 group that did not. An analysis of covariance was used to analyze the assessment data. The findings suggest that the students who did not use Thinking Maps performed significantly better than those who did use Thinking Maps, even though both groups showed positive mean score gains from 2010 to 2012 on the science portion of the CRCT. Limitations of the study, such as the lack of randomization and manipulation of the independent variable, suggest that further research is needed to fairly evaluate the program and its effectiveness. Also, the instructional setting and amount of time used for science instruction in the elementary classroom warrants additional investigation. Findings related to the implementation and use of graphic tools such as Thinking Maps will help school systems choose professional learning opportunities and effective instructional strategies to develop content literacy.

    Kozlenko, Brittany Hunter

    This study used the 2009 National Assessment of Educational Progress (NAEP) science restricted data-set for twelfth graders. The NAEP data used in this research study is derived from a sample group of 11,100 twelfth grade students that represented a national population of over 3,000,000 twelfth grade students enrolled in science in the United States in 2009. The researcher chose the NAEP data set because it provided a national sample using uniform questions. This study investigated how the factors of socioeconomic status (SES), parental education level, mode of instruction, and affective disposition affect twelfth grade students' physical science achievement levels in school for the sample population and subgroups for gender. The factors mode of instruction and affective disposition were built through factor analysis based on available questions from the student surveys. All four factors were found to be significant predictors of physical science achievement for the sample population. NAEP exams are administered to a national sample that represents the population of American students enrolled in public and private schools. This was a non-experimental study that adds to the literature on factors that impact physical science for both genders. A gender gap is essentially nonexistent at the fourth grade level but appears at the eighth grade level in science based on information from NAEP (NCES, 1997). The results of the study can be used to make recommendation for policy change to diminish this gender gap in the future. Educators need to be using research to make instructional decisions; research-based instruction helps all students.

  5. The effects of school policies and practices on eighth-grade science achievement: A multilevel analysis of TIMSS

    Science.gov (United States)

    Smyth, Carol Ann Mary

    Identifying the relative importance of both alterable school policies and fairly stable contextual factors as they relate to middle level science achievement, a domain of identified national concern, requires simultaneous investigation of multilevel predictors (i.e., student level and school level) specific to the grade level and academic subject area. The school level factors are predictors associated with both the school (e.g., average socioeconomic status, tracking, and instructional time) and the classroom (e.g., average academic press of peers, teacher collaboration, and instructional strategies). The current study assessed the effects of school policies, practices, and contextual factors on the science achievement of eighth grade students. These influences were considered to be both additive (i.e., influencing the mean achievement in a school after controlling for student characteristics) and interactive (i.e., affecting the relationships between student background characteristics and individual achievement). To account for the nested structure of predictors and cross level interactions among predictors, a multilevel model for middle level science achievement was estimated using hierarchical linear modeling (HLM) with data collected from eighth grade students, science teachers, and administrators in 1995 as part of the Third International Mathematics and Science Study (TIMSS). The major findings of this research suggest that although average eighth grade science achievement in a school was primarily associated with the contextual characteristics of the classroom and the school (e.g., average socioeconomic status and average academic press), both the academic differentiating influence of prior achievement and the social differentiating influence of parental education on the science achievement of eighth grade students were related not only to contextual characteristics of the classroom and the school, but also to the instructional policies of the classroom

    Ledger, Antoinette Frances

    This study sought to examine whether collaborative concept mapping would affect the achievement, science self-efficacy and attitude toward science of female eighth grade science students. The research questions are: (1) Will the use of collaborative concept mapping affect the achievement of female students in science? (2) Will the use of collaborative concept mapping affect the science self-efficacy of female students? (3) Will the use of collaborative concept mapping affect the attitudes of females toward science? The study was quasi-experimental and utilized a pretest-posttest design for both experimental and control groups. Eighth grade female and male students from three schools in a large northeastern school district participated in this study. The achievement test consisted of 10 multiple choice and two open-response questions and used questions from state-wide and national assessments as well as teacher-constructed items. A 29 item Likert type instrument (McMillan, 1992) was administered to measure science self-efficacy and attitude toward science. The study was of 12 weeks duration. During the study, experimental group students were asked to perform collaborative concept map construction in single sex dyads using specific terms designated by the classroom teacher and the researcher. During classroom visitations, student perceptions of collaborative concept mapping were collected and were used to provide insight into the results of the quantitative data analysis. Data from the pre and posttest instruments were analyzed for both experimental and control groups using t-tests. Additionally, the three teachers were interviewed and their perceptions of the study were also used to gain insight into the results of the study. The analysis of data showed that experimental group females showed significantly higher gains in achievement than control group females. An additional analysis of data showed experimental group males showed significantly greater gains in

    The interest in raising levels of achievement in math and science has led to a focus on investigating the factors that shape achievement in these subjects (Lamb & Fullarton, 2002) as well as understanding how these factors operate across countries (Baker, Fabrega, Galindo, & Mishook, 2004). The current study examined the individual student factors and classroom factors on fourth grade science achievement within and across five countries. Guided by the previous school learning models, the elements of students' science learning were categorized as student-level and classroom-level factors. The student-level factors included gender, self-confidence in science, and home resources. The classroom-level factors included teacher characteristics, instructional variables and classroom composition. Results for the United States and four other countries, Singapore, Japan, Australia, and Scotland were reported. Multilevel effects of student and classroom variables were examined through Hierarchical Linear Modeling (HLM) using the Trends in International Mathematics and Science Study (TIMSS) 2003 fourth grade dataset. The outcome variable was the TIMSS 2003 science score. Overall, the results of this study showed that selected student background characteristics were consistently related to elementary science achievement in countries investigated. At the student-level, higher levels of home resources and self-confidence and at the classroom-level, higher levels of class mean home resources yielded higher science scores on the TIMSS 2003. In general, teacher and instructional variables were minimally related to science achievement. There was evidence of positive effects of teacher support in the U.S. and Singapore. The emphasis on science inquiry was positively related to science achievement in Singapore and negatively related in the U.S. and Australia. Experimental studies that investigate the impacts of teacher and instructional factors on elementary science achievement are

    There are many barriers to using science to inform conservation policy and practice. Conservation scientists wishing to produce management-relevant science must balance this goal with the imperative of demonstrating novelty and rigor in their science. Decision makers seeking to make evidence-based decisions must balance a desire for knowledge with the need to act despite uncertainty. Generating science that will effectively inform management decisions requires that the production of information (the components of knowledge) be salient (relevant and timely), credible (authoritative, believable, and trusted), and legitimate (developed via a process that considers the values and perspectives of all relevant actors) in the eyes of both researchers and decision makers. We perceive 3 key challenges for those hoping to generate conservation science that achieves all 3 of these information characteristics. First, scientific and management audiences can have contrasting perceptions about the salience of research. Second, the pursuit of scientific credibility can come at the cost of salience and legitimacy in the eyes of decision makers, and, third, different actors can have conflicting views about what constitutes legitimate information. We highlight 4 institutional frameworks that can facilitate science that will inform management: boundary organizations (environmental organizations that span the boundary between science and management), research scientists embedded in resource management agencies, formal links between decision makers and scientists at research-focused institutions, and training programs for conservation professionals. Although these are not the only approaches to generating boundary-spanning science, nor are they mutually exclusive, they provide mechanisms for promoting communication, translation, and mediation across the knowledge-action boundary. We believe that despite the challenges, conservation science should strive to be a boundary science, which

  10. Stereotype threat's effect on women's achievement in chemistry: The interaction of achievement goal orientation for women in science majors

    Conway-Klaassen, Janice Marjorie

    "Stereotype threat is being at risk of confirming, as a self-characteristic, a negative stereotype about one's group" (C. M. Steele & Aronson, 1995, p. 797). A stereotype threat effect then is described as the detrimental impact on a person's performance or achievement measurements when they are placed in a stereotype threat environment. For women, the negative stereotype that exists in our culture states that women are typically not as capable as men in mathematics or science subjects. This study specifically explored the potential impact of stereotype threat on women who have chosen a science-based college major. They were tested in the domain of chemistry, which is related to mathematics and often involves high level of mathematics skills. I attempted to generate a stereotype threat in the participants through describing a chemistry challenge exam as either one that had consistently shown a gender bias against women and to create a nullification effect by describing the exam as one that had shown no gender bias in the past. In the third experimental condition acting as a control, participants received only generic instructions related to taking the test itself. The second part of this study investigated whether stereotype threat effects could impact women's achievement goal orientations. In previous studies performance avoidance goal orientations have been associated with individuals placed in a stereotype threat environment. The findings on the stereotype threat effect were not significant for the chemistry challenge test achievement scores. This may be due to several factors. One factor may be the design of the chemistry challenge test and the instructions for the test. The other factor may be the women in this study. As individuals who have chosen a science based major, they may have developed coping skills and strategies that reduced the impact of a stereotype threat. It is also possible that the testing environment itself generated an implicit stereotype

  11. The impact of podcasts, screencasts, and vodcasts on student achievement in the science classroom

    Pena, Ruben, Jr.

    Educators in today's society are in search for different ways to reach their students in order to keep them engaged and active in the learning process. There are several strategies that teachers have utilized in the classroom in order to reach all students. Now seen more in the classroom is the use of technology in one form or another. There are several types of technologies that one may employ while in the classroom, but seen more recently is the use of podcasts, screencasts, and vodcasts. The major purpose of the study was to investigate the impact of using podcasts, screencasts, and vodcasts in conjunction with science curriculum on student academic achievement. Two intermediate schools from the south Texas region were chosen as a convenience sample for the study because one school utilized the technology of podcasts, screencasts, and vodcasts at the student created level while the other school did not utilize podcasts, screencasts, and vodcasts at the student created level. The researcher collected scores from curriculum based assessments that were aligned with the Texas Essential Knowledge and Skills (TEKS) for comparison between the two different groups, while controlling grade five science TAKS scores for group equalization. Once all data was collected, scores were entered into the Statistical Package for the Social Sciences (SPSS) and were analyzed using an analysis of covariance. The ANCOVA allowed the researcher to see that differences among curriculum based assessments scores existed between the two different schools. Scores were higher for the students who utilized podcasts, screencasts, and vodcasts at the student created level when compared to those scores for students who did not utilize podcasts, screencasts, and vodcasts at the student created level. This study showed the benefits reaped of having students create their own podcasts, screencasts, and vodcasts. Having students create their own technology has them actively engaged in the learning

    This study sought to identify those organizational health factors that might have overriding influence on the achievement level of students in science in Sri Lankan secondary schools. This study involved 752 students, 33 science teachers, and 10 principals from two different districts, Ampara and Colombo, in Sri Lanka. Ten Tamil medium, secondary level, public schools were selected to participate in this study. Data were collected using four types of instruments: a questionnaire for pupils; interview schedules for science teachers and principals; checklists for classroom/school facilities, science laboratory facilities, and science practicals; and a science achievement test. The analysis focused on the collective perceptions of students, science teachers, and principals. Regression and path analyses were used as major analysis techniques, and the qualitative data provided by science teachers and principals were considered for a crosschecking of the quantitative inferences. The researcher found teacher affiliation, academic emphasis, and instructional leadership of the principal, in descending order, were the overriding influential factors on the achievement level of students in science in Sri Lankan secondary schools. At the same time a similar descending order was found in their mean values and qualities. The researcher concluded that increasing the quality of the organizational health factors in Sri Lankan secondary schools would result in improved better achievement in science. The findings further indicate that instructional leadership of the principal had both direct and indirect effects on students' achievement in science when academic emphasis and teacher affiliation were taken into account. In addition, the resource support of the principal did not make any difference in students' science achievement and the findings stress the availability of the resources for individual students instead of assuming the general facilities of the school are available to all

  13. Growing minds: The effect of school gardening programs on the science achievement of elementary students

    Science.gov (United States)

    Klemmer, Cynthia Davis

    Science literacy refers to a basic knowledge and understanding of science concepts and processes needed to consider issues and make choices on a daily basis in an increasingly technology-driven society. A critical precursor to producing science literate adults is actively involving children in science while they are young. National and state (TX) science standards advocate the use of constructivist methods including hands-on, experiential activities that foster the development of science process skills through real-world investigations. School gardens show promise as a tool for implementing these guidelines by providing living laboratories for active science. Gardens offer opportunities for a variety of hands-on investigations, enabling students to apply and practice science skills. School gardens are increasing in popularity; however, little research data exists attesting to their actual effectiveness in enhancing students' science achievement. The study used a quasi-experimental posttest-only research design to assess the effects of a school gardening program on the science achievement of 3rd, 4th, and 5th grade elementary students. The sample consisted of 647 students from seven elementary schools in Temple, Texas. The experimental group participated in school gardening activities as part of their science curriculum. The control group did not garden and were taught using traditional classroom-based methods. Results showed higher scores for students in the experimental group which were statistically significant. Post-hoc tests using Scheffe's method revealed that these differences were attributed to the 5th grade. No statistical significance was found between girls and boys in the experimental group, indicating that gardening was equally effective for both genders. Within each gender, statistical significance was found between males in the experimental and control groups at all three grade levels, and for females in the 5 th grade. This research indicated that

  14. Two-year study relating adolescents' self-concept and gender role perceptions to achievement and attitudes toward science

    Handley, Herbert M.; Morse, Linda W.

    To assess the developmental relationship of perceptions of self-concept and gender role identification with adolescents' attitudes and achievement in science, a two-year longitudinal study was conducted. A battery of instruments assessing 16 dimensions of self-concept/gender role identifications was employed to predict students' achievement and attitudes toward science. Specific behaviors studied included self-concept in school and science and mathematics, attitudes toward appropriate gender roles in science activities and careers, and self-perceptions of masculine and feminine traits. One hundred and fifty-five adolescents, enrolled, respectively, in the seventh and eighth grades, participated in the study. Through Fisher z transformations of correlation coefficients, differences in relationships between these two sets of variables were studied for males and females during the two years. Results indicated that students' self-concepts/gender role perceptions were related to both achievement and attitudes toward science, but more related to attitudes than achievement. These relationships became more pronounced for students as they matured from seventh to eighth graders.

    Whitford, Melinda M.

    Science educational reforms have placed major emphasis on improving science classroom instruction and it is therefore vital to study opportunity-to-learn (OTL) variables related to student science learning experiences and teacher teaching practices. This study will identify relationships between OTL and student science achievement and will identify OTL predictors of students' attainment at various distinct achievement levels (low/intermediate/high/advanced). Specifically, the study (a) address limitations of previous studies by examining a large number of independent and control variables that may impact students' science achievement and (b) it will test hypotheses of structural relations to how the identified predictors and mediating factors impact on student achievement levels. The study will follow a multi-stage and integrated bottom-up and top-down approach to identify predictors of students' achievement levels on standardized tests using TIMSS 2011 dataset. Data mining or pattern recognition, a bottom-up approach will identify the most prevalent association patterns between different student achievement levels and variables related to student science learning experiences, teacher teaching practices and home and school environments. The second stage is a top-down approach, testing structural equation models of relations between the significant predictors and students' achievement levels according.

    Caukin, Nancy S.

    The purpose of this mixed-methods study was to determine if employing the writing-to-learn strategy known as a "Science Writing Heuristic" would positively effect students' science achievement, science self-efficacy, and scientific epistemological view. The publications Science for All American, Blueprints for Reform: Project 2061 (AAAS, 1990; 1998) and National Science Education Standards (NRC 1996) strongly encourage science education that is student-centered, inquiry-based, active rather than passive, increases students' science literacy, and moves students towards a constructivist view of science. The capacity to learn, reason, problem solve, think critically and construct new knowledge can potentially be experienced through writing (Irmscher, 1979; Klein, 1999; Applebee, 1984). Science Writing Heuristic (SWH) is a tool for designing science experiences that move away from "cookbook" experiences and allows students to design experiences based on their own ideas and questions. This non-traditional classroom strategy focuses on claims that students make based on evidence, compares those claims with their peers and compares those claims with the established science community. Students engage in reflection, meaning making based on their experiences, and demonstrate those understandings in multiple ways (Hand, 2004; Keys et al, 1999, Poock, nd.). This study involved secondary honors chemistry students in a rural prek-12 school in Middle Tennessee. There were n = 23 students in the group and n = 8 in the control group. Both groups participated in a five-week study of gases. The treatment group received the instructional strategy known as Science Writing Heuristic and the control group received traditional teacher-centered science instruction. The quantitative results showed that females in the treatment group outscored their male counterparts by 11% on the science achievement portion of the study and the males in the control group had a more constructivist scientific

    Ingram, Samantha Jones

    The purpose of this study was to investigate the effects of the contextual learning method on science performance, attitudes toward science, and motivational factors that influence high school students to learn science. Gender differences in science performance and attitudes toward science were also investigated. The sample included four tenth-grade classes of African-American students enrolled in Chemistry I. All students were required to review for the Alabama High School Graduation Exam in Science. Students were administered a science pretest and posttest to measure science performance. A two-way analysis of covariance was performed on the test data. The results showed a main effect of contextual learning instruction on science achievement and no significant differences between females' and males' performance in science. The Science Attitude and the Alabama High School Graduation Exam (AHSGE) Review Class Surveys were administered to assess students' beliefs and attitudes toward science. The Science Attitude Survey results indicated a control effect in three subscales: perception of guardian's attitude, attitude toward success in science, and perception of teacher's attitude. No significant differences resulted between males and females in their beliefs about science from the attitude survey. However, students' attitudes toward science were more favorable in the contextual learning classes based on the results of the Review Class Survey. The survey data revealed that both males and females in the contextual classes had positive attitudes toward science and toward being active participants in the learning process. Qualitative data on student motivation were collected to examine the meaningfulness of the contextual learning content and materials. The majority of the students in the treatment (96%) and the control groups (86%) reported high interest in the lesson on Newton's three laws of motion. Both the treatment and the control groups indicated their interest

    2017-11-01

    Contemporary science educators must equip their students with the knowledge and practical know-how to connect multiple disciplines like mathematics, computing and the natural sciences to gain a richer and deeper understanding of a scientific problem. However, many biology and earth science students are prejudiced against mathematics due to negative emotions like high mathematical anxiety and low mathematical confidence. Here, we present a theoretical framework that investigates linkages between student engagement, mathematical anxiety, mathematical confidence, student achievement and subject mastery. We implement this framework in a large, first-year interdisciplinary science subject and monitor its impact over several years from 2010 to 2015. The implementation of the framework coincided with an easing of anxiety and enhanced confidence, as well as higher student satisfaction, retention and achievement. The framework offers interdisciplinary science educators greater flexibility and confidence in their approach to designing and delivering subjects that rely on mathematical concepts and practices.

    2016-05-01

    Comics are popular with adolescents because of their features of humor, narrative, and visual imagery. The purposes of this study were to examine the learning outcomes and emotional perceptions of reading a science comic book and a science text booklet for students of different levels of achievement, and to explore the main factors of the two media which attract high-school students to learn science. A mixed-method quasi-experimental design was adopted. The participants were 697 grade ten students from eight schools with different levels of academic achievement. Two similar classes in each of the eight schools were assigned as the comic group or the text group. The results indicated that the science comic book benefited medium achievers more than the science text booklet did, but the contrary result was found for the high achievers. In comparison, the two media benefited the low achievers equally, but both had only a limited effect due to the students' lack of prior knowledge. We conclude four kinds of evidence, including perceived difficulty of comprehension, reasons for interest/disinterest, emotional perceptions of learning science, and learning time, to support the phenomenon of the learning benefit of media specific to certain achievers' science learning.

  9. The effects of formative assessment on student self-regulation, motivational beliefs, and achievement in elementary science

    King, Melissa Digennaro

    Goals 2000 set forth a bold vision for U.S. students: they would be "first in the world in science and mathematics" by the year 2000. Performance indicators such as the TIMSS-R (1999) and NAEP (2000) reports suggest that U.S. students have not yet reached that goal. This study intended to learn how specific assessment strategies might contribute to improved student performance in science. This quasi-experimental study investigated the effects of formative assessment with reflection on students' motivational beliefs, self-regulatory skills, and achievement in elementary science. The study aimed to find out whether and how classroom applications of formative assessment during science instruction might influence fifth-grade students' attitudes and self-perceptions about science learning, self-regulatory learning behaviors, and achievement. To explore the effects of the assessment intervention, the study utilized a mixed methods approach involving quantitative and qualitative investigations of treatment and control groups during a four-week intervention period. Quantitative measures included student self-report surveys administered pre- and post-treatment and an end-of-unit science test. Qualitative measures included classroom observations, student interviews (post-treatment), and a teacher interview (post-treatment). Findings indicated that the fifth-grade students in this study had positive attitudes toward science and high levels of self-efficacy for science. Results suggested that these elementary students employed a wide variety of cognitive and metacognitive strategies to support science learning. Findings revealed that these fifth graders believed formative assessment with reflection was beneficial for science learning outcomes. Research results did not show that the formative assessment intervention contributed to significant differences between treatment and control groups. However, the data revealed different levels of academic achievement and self

    Despite a few international comparisons of the evolutionary beliefs of the general public, comparatively less research has focused on science teachers. Cross-cultural studies offer profitable opportunities for exploring the interactions among knowledge and belief variables in regard to evolution in different socio-cultural contexts. We investigated the evolutionary worldviews of pre-service science teachers from Asia (specifically South Korea), a region often excluded from international comparisons. We compared Korean and American science teachers': (1) understandings of evolution and the nature of science, and (2) acceptance of evolution in order to elucidate how knowledge and belief relationships are manifested in different cultural contexts. We found that Korean science teachers exhibited 'moderate' evolutionary acceptance levels comparable to or lower than American science teacher samples. Gender was significantly related to Korean teachers' evolution content knowledge and acceptance of evolution, with female Christian biology teachers displaying the lowest values on all measures. Korean science teachers' understandings of nature of science were significantly related to their acceptance and understanding of evolution; this relationship appears to transcend cultural boundaries. Our new data on Korean teachers, combined with studies from more than 20 other nations, expose the global nature of science teacher ambivalence or antipathy toward evolutionary knowledge.

  11. Factors affecting student achievement in science: A study of teacher beliefs

    Science.gov (United States)

    Hayes, Jonathan

    This study employed a mixed methods and mixed model research design to explore secondary science teachers' beliefs. Specifically, this study focused on factors that secondary science teachers believe affect student achievement in science, and the extent to which teacher beliefs transfer to teacher practice. This study is significant because the outcomes may inform professional development and policy decisions at the school, district, and provincial level. Results from self-reporting data of 82 secondary science teachers indicate that teacher beliefs in each of the fourteen topics surveyed (Classroom Management, Learning Styles, Inclusion, Equity, Science-Technology-Society (STS), Formative Assessment, Summative Assessment, Constructivism, Thematic Approach, Hands-On/Minds-On Activities, The Nature of Science, Science Subject Matter, Electronic Learning and Cooperative Learning) are positive for most Prince Edward Island (P.E.I.) secondary science teachers. Furthermore, secondary science teachers reported having strong beliefs in their ability to affect student learning (self-efficacy beliefs). However, it is apparent from the survey and interview data that teachers believe there are other influential factors that are preventing some students from learning despite the teachers' best efforts and ability. Regarding implementation, this study indicates that beliefs and the enactment of beliefs in classroom practice are positively correlated. The data also shows that at least seventy percent of teachers reported that they implement practices consistent with all but two topics -- The Nature of Science and Electronic Learning -- at least once a week. The findings of this study are discussed in the context of the P.E.I. secondary science setting. Limitations and implications of this study are also addressed.

    2004-10-01

    This article is about one school district's effort to reform its elementary science curriculum through a program of professional development called Science, Parents, Activities and Literature (Science PALs). The differential exposure of the district's K-6 teachers to Science PALs and differences in how well teachers implemented Science PALs-type inquiry strategies allowed us to conduct a quasi-experimental study of the impact of Science PALs on student achievement and attitudes. We measured achievement with an instrument based on items taken from the Third International Mathematics and Science Study (TIMSS; International Association for the Evaluation of Educational Achievement, [1997]) and selected attitudes about science with the Student Perceptions of Classroom Climate (SPOCC; Yore et al., [1998]), an instrument that we designed. Our analyses of student attitude scores as a function of years of teacher participation in Science PALs and supervisor's rating of a teacher's implementation of the project's instructional approaches showed a significant overall positive impact on student attitudes toward school science. Student TIMSS scores on multiple-choice items or constructed-response items did not improve significantly when analyzed by the number of years a student's teacher was involved in the Science PALs effort or by the supervisor's rating of that implementation. We found no significant differences in attitude or achievement scores among students taught by a series of teachers rated high, medium, or low in quality of implementation by the district's science supervisor. We discuss possible explanations for the lack of clear and positive connections between Science PALs and student performance in light of the increased focus on accountability in reform projects.

    Clarke, William Gordon

    English language learners (ELLs) demonstrate lower academic performance and have lower graduation and higher dropout rates than their non-ELL peers. The primary purpose of this correlational quantitative study was to investigate the relationship between the use of graphic organizer-infused science instruction and science learning of high school ELLs. Another objective was to determine if the method of instruction, socioeconomic status (SES), gender, and English language proficiency (ELP) were predictors of academic achievement of high school ELLs. Data were gathered from a New York City (NYC) high school fall 2012-2013 archival records of 145 ninth-grade ELLs who had received biology instruction in freestanding English as a second language (ESL) classes, followed by a test of their learning of the material. Fifty-four (37.2%) of these records were of students who had learned science by the conventional textbook method, and 91 (62.8%) by using graphic organizers. Data analysis employed the Statistical Package for the Social Sciences (SPSS) software for multiple regression analysis, which found graphic organizer use to be a significant predictor of New York State Regents Living Environment (NYSRLE) test scores (p < .01). One significant regression model was returned whereby, when combined, the four predictor variables (method of instruction, SES, gender, and ELP) explained 36% of the variance of the NYSRLE score. Implications of the study findings noted graphic organizer use as advantageous for ELL science achievement. Recommendations made for practice were for (a) the adoption of graphic organizer infused-instruction, (b) establishment of a protocol for the implementation of graphic organizer-infused instruction, and (c) increased length of graphic organizer instructional time. Recommendations made for future research were (a) a replication quantitative correlational study in two or more high schools, (b) a quantitative quasi-experimental quantitative study to

    1998-09-01

    Historically, researchers have reported an achievement difference between females and males on standardized science tests. These differences have been reported to be based upon science knowledge, abstract reasoning skills, mathematical abilities, and cultural and social phenomena. This research was designed to determine how mastery of specific science content from public school curricula might be evaluated with performance-based assessment models, without producing gender achievement differences. The assessment instruments used were Harcourt Brace Educational Measurement's GOALSsp°ler: A Performance-Based Measure of Achievement and the performance-based portion of the Stanford Achievement Testspcopyright, Ninth Edition. The identified independent variables were test, gender, ethnicity, and grade level. A 2 x 2 x 6 x 12 (test x gender x ethnicity x grade) factorial experimental design was used to organize the data. A stratified random sample (N = 2400) was selected from a national pool of norming data: N = 1200 from the GOALSsp°ler group and N = 1200 from the SAT9spcopyright group. The ANOVA analysis yielded mixed results. The factors of test, gender, ethnicity by grade, gender by grade, and gender by grade by ethnicity failed to produce significant results (alpha = 0.05). The factors yielding significant results were ethnicity, grade, and ethnicity by grade. Therefore, no significant differences were found between female and male achievement on these performance-based assessments.

    Clifford, Betsey A.

    The Massachusetts Department of Elementary and Secondary Education (DESE) released proposed Science and Technology/Engineering standards in 2013 outlining the concepts that should be taught at each grade level. Previously, standards were in grade spans and each district determined the method of implementation. There are two different methods used teaching middle school science: integrated and discipline-based. In the proposed standards, the Massachusetts DESE uses grade-by-grade standards using an integrated approach. It was not known if there is a statistically significant difference in student achievement on the 8th grade science MCAS assessment for students taught with an integrated or discipline-based approach. The results on the 8th grade science MCAS test from six public school districts from 2010 -- 2013 were collected and analyzed. The methodology used was quantitative. Results of an ANOVA showed that there was no statistically significant difference in overall student achievement between the two curriculum models. Furthermore, there was no statistically significant difference for the various domains: Earth and Space Science, Life Science, Physical Science, and Technology/Engineering. This information is useful for districts hesitant to make the change from a discipline-based approach to an integrated approach. More research should be conducted on this topic with a larger sample size to better support the results.

  7. Defining the Relationship of Student Achievement Between STEM Subjects Through Canonical Correlation Analysis of 2011 Trends in International Mathematics and Science Study (TIMSS) Data

    Science.gov (United States)

    O'Neal, Melissa Jean

    Canonical correlation analysis was used to analyze data from Trends in International Mathematics and Science Study (TIMSS) 2011 achievement databases encompassing information from fourth/eighth grades. Student achievement in life science/biology was correlated with achievement in mathematics and other sciences across three analytical areas: mathematics and science student performance, achievement in cognitive domains, and achievement in content domains. Strong correlations between student achievement in life science/biology with achievement in mathematics and overall science occurred for both high- and low-performing education systems. Hence, partial emphases on the inter-subject connections did not always lead to a better student learning outcome in STEM education. In addition, student achievement in life science/biology was positively correlated with achievement in mathematics and science cognitive domains; these patterns held true for correlations of life science/biology with mathematics as well as other sciences. The importance of linking student learning experiences between and within STEM domains to support high performance on TIMSS assessments was indicated by correlations of moderate strength (57 TIMSS assessments was indicated by correlations of moderate strength (57 mathematics, and other sciences. At the eighth grade level, students who built increasing levels of cognitive complexity upon firm foundations were prepared for successful learning throughout their educational careers. The results from this investigation promote a holistic design of school learning opportunities to improve student achievement in life science/biology and other science, technology, engineering, and mathematics (STEM) subjects at the elementary and middle school levels. While the curriculum can vary from combined STEM subjects to separated mathematics or science courses, both professional learning communities (PLC) for teachers and problem-based learning (PBL) for learners can be

    Science educators have the common goal of helping students develop scientific literacy, including understanding of the nature of science (NOS). University faculties are challenged with the need to develop informed NOS views in several major student subpopulations, including science majors and nonscience majors. Research into NOS views of undergraduates, particularly science majors, has been limited. In this study, NOS views of undergraduates in introductory environmental science and upper-level animal behavior courses were measured using Likert items and open-ended prompts. Analysis revealed similarities in students' views between the two courses; both populations held a mix of naïve, transitional, and moderately informed views. Comparison of pre- and postcourse mean scores revealed significant changes in NOS views only in select aspects of NOS. Student scores on sections addressing six aspects of NOS were significantly different in most cases, showing notably uninformed views of the distinctions between scientific theories and laws. Evidence-based insight into student NOS views can aid in reforming undergraduate science courses and will add to faculty and researcher understanding of the impressions of science held by undergraduates, helping educators improve scientific literacy in future scientists and diverse college graduates.

  9. Interaction between examination type, anxiety state, and academic achievement in college science; an action-oriented research

    Zoller, Uri; Ben-Chaim, David

    The trait anxiety profile of future science teachers, as well as their preferences concerning types of examinations in science and mathematics, have been surveyed prior to the administration - within the various science courses - of several traditional and nontraditional types of examinations and the assessment of students' state anxieties as well as their respective performance, i.e., their academic achievements. Our major findings are that(a)Our students prefer by far examinations in which the emphasis is on understanding and analyzing rather than on knowing and remembering, that the use of any relevant material during the examinations be permitted, and that the time duration be practically unlimited (e.g., take-home-type examinations).(b)Students' state anxiety correlates with the type of the examination, with a tendency towards somewhat higher anxiety for females. The preferred types of examinations reduce test anxiety significantly, and result in higher grades accordingly.(c)The reduction of anxiety and the improvement in achievements as a function of the examination type are far more significant for low achievers compared with medium and high achievers.(d)Although teachers are aware of the student preferences, they persist in giving their students their own pet-type examinations.These results are discussed in terms of the implications for upgrading both science education and college student testing and assessment mechanisms.

    2011-12-01

    There is great concern over students' poor science achievement in the United States. Due to the lack of science achievement, students are not pursing science related careers resulting in an increase in outsourcing to other countries. Learning strategies such as concept mapping may ameliorate this situation by providing students with tools that encourage meaningful learning. The purpose of this quasi-experimental study was to measure the effects of three concept mapping learning strategies (concept identifying, proposition identifying, student generated) on urban middle school students' understanding of the circulatory system. Three intact classes of seventh-grade students were assigned to one of the three concept mapping strategies. The students were given a pretest on the circulatory system then learned and used their respective concept mapping strategies while learning about the circulatory system. At the conclusion of the study, students' science achievement was measured by performance on an achievement test and rubric scores of their respective concept identifying, proposition identifying, and student generated concept maps. The results of the study suggest that all three of the concept mapping strategies are effective in increasing students' science achievement. Additionally, the moderate significant correlations between the posttest and concept map scores of the current study established that concept maps are a useful measure of student knowledge. Lastly, the results of the current study also suggest that the concept identifying mapping strategy may be a useful scaffold in instructing students how to develop student generated concept maps.

    The purpose of this investigation was to examine the effects of a year long intensive extracurricular middle school science experience on the self-esteem, career goal orientation, and attitude toward science of eighth grade female students using both quantitative and qualitative methods. Sixteen self-selected eighth grade female students participated in extracurricular science experiences such as camping, rock climbing, specimen collecting and hiking, as well as meeting and interacting with female science role models. Data was collected using pre- and posttest methods using the Children's Attitude Toward Science Survey, the Coopersmith Self-Esteem Inventory, and the Self-Directed Search (SDS) Career Explorer. End of year science course grades were examined for seventh and eighth grades and compared to first semester high school grades. Qualitative data was in the form of: (1) focus group interviews conducted prior to field experiences, at the end of all field experiences, and at the end of the first semester of high school, and (2) journal entries from throughout the project. Qualitative data was examined for changes in student perceptions of science as a discipline, self as scientist, women in science, and social comparison of self in science.

  14. The relationship of attitudes toward science, cognitive style, and self-concept to achievement in chemistry at the secondary school level

    Science.gov (United States)

    Kirk, Gerald Richard

    There is currently a crisis in science education in the United States. This statement is based on the National Science Foundation's report stating that the nation's students, on average, still rank near the bottom in science and math achievement internationally. This crisis is the background of the problem for this study. This investigation studied learner variables that were thought to play a role in teaching chemistry at the secondary school level, and related them to achievement in the chemistry classroom. Among these, cognitive style (field dependence/independence), attitudes toward science, and self-concept had been given considerable attention by researchers in recent years. These variables were related to different competencies that could be used to measure the various types of achievement in the chemistry classroom at the secondary school level. These different competencies were called academic, laboratory, and problem solving achievement. Each of these chemistry achievement components may be related to a different set of learner variables, and the main purpose of this study was to investigate the nature of these relationships. Three instruments to determine attitudes toward science, cognitive style, and self-concept were used for data collection. Teacher grades were used to determine chemistry achievement for each student. Research questions were analyzed using Pearson Product Moment Correlation Coefficients and t-tests. Results indicated that field independence was significantly correlated with problem solving, academic, and laboratory achievement. Educational researchers should therefore investigate how to teach students to be more field independent so they can achieve at higher levels in chemistry. It was also true that better attitudes toward the social benefits and problems that accompany scientific progress were significantly correlated with higher achievement on all three academic measures in chemistry. This suggests that educational researchers

    Roberts, Patrice Helen

    This research was designed to determine the relationships among students' achievement scores on grade-level science content, on science content that was three years above-grade level, on attitudes toward instructional approaches, and learning-styles perceptual preferences when instructional approaches were multisensory versus traditional. The dependent variables for this investigation were scores on achievement posttests and scores on the attitude survey. The independent variables were the instructional strategy and students' perceptual preferences. The sample consisted of 74 educationally oriented seventh-grade students. The Learning Styles Inventory (LSI) (Dunn, Dunn, & Price, 1990) was administered to determine perceptual preferences. The control group was taught seventh-grade and tenth-grade science units using a traditional approach and the experimental group was instructed on the same units using multisensory instructional resources. The Semantic Differential Scale (SDS) (Pizzo, 1981) was administered to reveal attitudinal differences. The traditional unit included oral reading from the textbook, completing outlines, labeling diagrams, and correcting the outlines and diagrams as a class. The multisensory unit included five instructional stations established in different sections of the classroom to allow students to learn by: (a) manipulating Flip Chutes, (b) using Electroboards, (c) assembling Task Cards, (d) playing a kinesthetic Floor Game, and (e) reading an individual Programmed Learning Sequence. Audio tapes and scripts were provided at each location. Students circulated in groups of four from station to station. The data subjected to statistical analyses supported the use of a multisensory, rather than a traditional approach, for teaching science content that is above-grade level. T-tests revealed a positive and significant impact on achievement scores (p < 0.0007). No significance was detected on grade-level achievement nor on the perceptual

  1. Stories of Success: Understanding Academic Achievement of Hispanic Students in Science

    Science.gov (United States)

    Harris, Amanda

    A review of the literature shows that there is much evidence to suggest the challenges facing Hispanic students in American public schools. Hispanic enrollment in K--12 public schools has increased from 6 to 19% in the last thirty years, yet schools have not made adequate adjustments to accommodate this changing population. Issues such as remedial tracking and cultural differences have led to low high school graduate rates for Hispanic students and inequities in schooling experiences (Gay, 2000). Particularly in the area of science, Hispanic students struggle with academic success (Cole & Espinoza, 2008). Despite these obstacles, some Hispanic students are academically successful (Rochin & Mello, 2007; Merisotis & Kee, 2006). This dissertation tells the stories of these Hispanic students who have been successful in science in secondary public schools. This study followed a grounded theory methodology and utilized individual interviews to collect data about Hispanics who have demonstrated achievement in the area of science. Through the analysis of these interviews, factors were identified which may have contributed to the success of these Hispanics in the field of science. Implications for future practice in public schools are also discussed.

    Full Text Available BACKGROUND: Understanding personality variables and other important psychological traits in the university population appears topical particularly with respect to personality, motivation, health as well as overall academic achievement. A significant role is played by correlations of the monitored variables in relation to selected study specialization. OBJECTIVE: The main objective of the present study is to extend the knowledge on selected personality traits and the level of achievement motivation in a specific group of university students with respect to the diversity of their study specialization. METHODS: The study included a total of 522 students from Palacký University. These were students from the Faculty of Physical Culture (n = 118, Faculty of Education (n = 218 and Faculty of Science (n = 186. In terms of age, the study focused on young adults aged 19 to 26. In the research, psychodiagnostic methods were used to perform diagnostics and to fulfil the overall research plan. All diagnostic methods used are fully standardized and contain domestic normative values. We monitored variables such as personality, achievement motivation and achievement anxiety. Statistical result processing was conducted using the Statgraphics programme v. 9.0. Result processing was made using parametric as well as non-parametric statistical methods (Shapiro-Wilk, Mann-Whitney, Kruskal-Wallis, Spearman’s correlation. RESULTS: University students specialized in physical culture showed the highest values of extraversion and psychoticism, and clearly the lowest values of neuroticism compared to the students of education and natural sciences. The highest values of openness were observed in the students specialized in sports. In terms of the overall achievement motivation related to study specialization, almost identical values were observed. However, the students of physical culture showed significantly lower values of achievement debilitating anxiety

    Full Text Available The School Achievement Indicators Program (SAIP has been collecting data across Canada on 13- and 16-year-old student achievement in mathematics, in science, and in reading and writing since 1993. In 1999, it completed its second assessment cycle and was reviewed in Spring 2000. The review design included a survey of officials from all the school boards/districts that participated in the science assessment program held in 1999. The results of this study show that this stakeholder views as the most pressing issue for SAIP to succeed in its mandate, the need for development in four areas: a Increased teacher and student motivation to participate wholeheartedly in the program; b Effective dissemination options; c Leadership through innovation in teaching and in assessment practices despite high accountability orientation; and d Cost-effective, yet rigorous means of providing both snapshot information and longitudinal means of comparisons. Although universally appealing, such approaches have yet to be supported by sound educational theory and methodology.

    Sturdivant Allen, Anita Kay

    Students in Grade 9 exhibit high rates of grade retention and absenteeism. Educators have used different strategies that will increase the achievement of those students. The purpose of this study was to determine whether a relationship existed between student achievement and the strategy to use colored paper for Grade 9 science assignments and tests. Itten's color theory provided the theoretical framework. Itten was one of the first researchers to explore the notion that the human eye can detect wavelengths as colors and that those colors can engage and create order in the human brain. A sample of students assigned to 4 classroom teachers at one high school who volunteered to take part in the study for 18 weeks were used in this quantitative study. Teachers administered student assessments on blue, green, yellow, and white paper. Each class was assigned 1 of the 4 colors for 4.5 weeks. The classes were then assigned a different color for the same length of time until each class had exposure to all 4 colors. Physical science exams given to students in the same grade or subject were used as the dependent variable. An ANOVA indicated that the groups using blue paper scored the highest on the physical science exams; students who used white paper earned the lowest scores. When comparing all 3 groups using colored paper (all three colored paper groups combined into one group) to the white paper groups, t-test results indicated that students using any colored paper scored higher than students using white paper. Further research on the impact of colored paper on student academic performance is necessary. Implications for positive social change indicate that new knowledge about instructional tools that impact student achievement deserves more attention.

    2013-01-01

    Background Educational institutions play an important role in encouraging student engagement, being necessary to know how engaged are students at university and if this factor is involved in student success point and followed. To explore the association between academic engagement and achievement. Methods Cross-sectional study. The sample consisted of 304 students of Health Sciences. They were asked to fill out an on-line questionnaire. Academic achievements were calculated using three types of measurement. Results Positive correlations were found in all cases. Grade point average was the academic rate most strongly associated with engagement dimensions and this association is different for male and female students. The independent variables could explain between 18.9 and 23.9% of the variance (p < 0.05) in the population of university students being analyzed. Conclusions Engagement has been shown to be one of the many factors, which are positively involved, in the academic achievements of college students. PMID:23446005

  12. Student's social interaction in inquiry-based science education: how experiences of flow can increase motivation and achievement

    Ellwood, Robin; Abrams, Eleanor

    2017-02-01

    This research investigated how student social interactions within two approaches to an inquiry-based science curriculum could be related to student motivation and achievement outcomes. This qualitative case study consisted of two cases, Off-Campus and On-Campus, and used ethnographic techniques of participant observation. Research participants included eight eighth grade girls, aged 13-14 years old. Data sources included formal and informal participant interviews, participant journal reflections, curriculum artifacts including quizzes, worksheets, and student-generated research posters, digital video and audio recordings, photographs, and researcher field notes. Data were transcribed verbatim and coded, then collapsed into emergent themes using NVIVO 9. The results of this research illustrate how setting conditions that promote focused concentration and communicative interactions can be positively related to student motivation and achievement outcomes in inquiry-based science. Participants in the Off-Campus case experienced more frequent states of focused concentration and out performed their peers in the On-Campus case on 46 % of classroom assignments. Off-Campus participants also designed and implemented a more cognitively complex research project, provided more in-depth analyses of their research results, and expanded their perceptions of what it means to act like a scientist to a greater extent than participants in the On-Campus case. These results can be understood in relation to Flow Theory. Student interactions that promoted the criteria necessary for initiating flow, which included having clearly defined goals, receiving immediate feedback, and maintaining a balance between challenges and skills, fostered enhanced student motivation and achievement outcomes. Implications for science teaching and future research include shifting the current focus in inquiry-based science from a continuum that progresses from teacher-directed to open inquiry experiences to a

  13. The Integration of Mathematics in Middle School Science: Student and Teacher Impacts Related to Science Achievement and Attitudes Towards Integration

    Science.gov (United States)

    McHugh, Luisa

    Contemporary research has suggested that in order for students to compete globally in the 21st century workplace, pedagogy must shift to include the integration of science and mathematics, where teachers effectively incorporate the two disciplines seamlessly. Mathematics facilitates a deeper understanding of science concepts and has been linked to improved student perception of the integration of science and mathematics. Although there is adequate literature to substantiate students' positive responses to integration in terms of attitudes, there has been little empirical data to support significant academic improvement when both disciplines are taught in an integrated method. This research study, conducted at several school districts on Long Island and New York City, New York, examined teachers' attitudes toward integration and students' attitudes about, and achievement on assessments in, an integrated 8th grade science classroom compared to students in a non-integrated classroom. An examination of these parameters was conducted to analyze the impact of the sizeable investment of time and resources needed to teach an integrated curriculum effectively. These resources included substantial teacher training, planning time, collaboration with colleagues, and administration of student assessments. The findings suggest that students had positive outcomes associated with experiencing an integrated science and mathematics curriculum, though these were only weakly correlated with teacher confidence in implementing the integrated model successfully. The positive outcomes included the ability of students to understand scientific concepts within a concrete mathematical framework, improved confidence in applying mathematics to scientific ideas, and increased agreement with the usefulness of mathematics in interpreting science concepts. Implications of these research findings may be of benefit to educators and policymakers looking to adapt integrated curricula in order to

    Examination of Saudi Arabian educational practices is scarce, but increasingly important, especially in light of the country's pace in worldwide mathematics and science rankings. The purpose of the study is to understand and evaluate parental influence on male children's science education achievements in Saudi Arabia. Parental level of education and participant's choice of science major were used to identify groups for the purpose of data analysis. Data were gathered using five independent variables concerning parental educational practices (attitude, involvement, autonomy support, structure and control) and the dependent variable of science scores in high school. The sample consisted of 338 participants and was arbitrarily drawn from the science-based colleges (medical, engineering, and natural science) at Jazan University in Saudi Arabia. The data were tested using Pearson's analysis, backward multiple regression, one way ANOVA and independent t-test. The findings of the study reveal significant correlations for all five of the variables. Multiple regressions revealed that all five of the parents' educational practices indicators combined together could explain 19% of the variance in science scores and parental attitude toward science and educational involvement combined accounted for more than 18% of the variance. Analysis indicates that no significant difference is attributable to parental involvement and educational level. This finding is important because it indicates that, in Saudi Arabia, results are not consistent with research in Western or other Asian contexts.

  16. Analyzing Turkey's data from TIMSS 2007 to investigate regional disparities in eighth grade science achievement

    Science.gov (United States)

    Erberber, Ebru

    Turkey is expected to be a full member of the European Union (EU) by 2013. In the course of its integration into the EU, Turkey has been simultaneously facing access, quality, and equity issues in education. Over the past decade, substantial progress has been made on increasing the access. However, improving the country's low level of education quality and achieving equity in quality education across the regions continue to be a monumental challenge in Turkey. Most recently, results from the Trends in International Mathematics and Science Study (TIMSS) 2007 indicated that Turkey's educational achievement at the eighth grade, the end of compulsory primary education in Turkey, was far below that of other countries in the EU. Considering Turkey's long standing socioeconomic disparities between the western and eastern parts of the country, the challenges of improving overall education quality are coupled with the challenges of achieving equity in learning outcomes for students across the regions. This dissertation used data from TIMSS 2007 to document the extent of Turkey's regional differences in science achievement at the eighth grade and to investigate factors associated with these differences. Findings from a series of analyses using hierarchical linear models suggested that attempts to increase Turkish students' achievement and close the achievement gaps between regions should target the students in the undeveloped regions, particularly in Southeastern Anatolia and Eastern Anatolia. Designing interventions to improve competency in Turkish and to compensate for the shortcomings of insufficient parental education, limited home educational resources, poor school climate for academic achievement, and inadequate instructional equipment and facilities might be expected to close the regional achievement gaps as well as raise the overall achievement level in Turkey.

  18. The effectiveness of Family Science and Technology Workshops on parental involvement, student achievement, and student curiosity

    Science.gov (United States)

    Kosten, Lora Bechard

    The literature suggests that parental involvement in schools results in positive changes in students and that schools need to provide opportunities for parents to share in the learning process. Workshops are an effective method of engaging parents in the education of their children. This dissertation studies the effects of voluntary Family Science and Technology Workshops on elementary children's science interest and achievement, as well as on parents' collaboration in their child's education. The study involved 35 second and third-grade students and their parents who volunteered to participate. The parental volunteers were randomly assigned to either the control group (children attending the workshops without a parent) or the treatment group (children attending the workshops with a parent). The study was conducted in the Fall of 1995 over a four-week period. The Analysis of Variance (ANOVA) and Kruskal-Wallis tests were used to determine the effects of the workshops on children's science achievement and science curiosity, as well as on parents' involvement with their child's education. The study revealed that there was no significant statistical difference at the.05 level between the treatment/control groups in children's science achievement or science curiosity, or in parent's involvement with their children's education. However, the study did focus parental attention on effective education and points the way to more extensive research in this critical learning area. This dual study, that is, the effects of teaching basic technology to young students with the support of their parents, reflects the focus of the Salve Regina University Ph.D. program in which technology is examined in its effects on humans. In essence, this program investigates what it means to be human in an age of advanced technology.

    Full Text Available The article discusses the results of empirical study of the association between variables of persistence and academic achievement in foreign languages. The sample includes students of the Faculty of Physics, Mathematics and Natural Science at the RUDN University ( n = 115, divided into 5 subsamples, two of which are featured in the present study (the most and the least successful students subsamples. Persistence as a personality trait is studied within A.I. Krupnov’s system-functional approach. A.I. Krupnov’s paper-and-pencil test was used to measure persistence variables. Academic achievement was measured according to the four parameters: Phonetics, Grammar, Speaking and Political vocabulary based on the grades students received during the academic year. The analysis revealed that persistence displays different associations with academic achievement variables in more and less successful students subsamples, the general prominence of this trait is more important for unsuccessful students. Phonetics is the academic achievement variable most associated with persistence due to its nature, a skill one can acquire through hard work and practice which is the definition of persistence. Grammar as an academic achievement variable is not associated with persistence and probably relates to other factors. Unsuccessful students may have difficulties in separating various aspects of language acquisition from each other which should be taken into consideration by the teachers.

Taking the students' opinions into account, it is possible to study the efficacy of education in terms of learning and achieving educational goals. (1In periodontics and restorative departments of Shahed and Tehran University of Medical Sciences, it is reported that, achieving educational goals is not poss-ible (2. Also, some studies have reported the inadequacy of educational objectives in anesthesia clerkship from the viewpoint of medical students (3. In this descriptive-analytic study, 166 medical students of neurology wards at Imam Reza Hospital in Kermanshah during 2011- 2012 were selected via a survey to study the achievement rate of educational goals. We used a questionnaire to collect data. Reliability of the questionnaire (including content and face validity was obtained via consulting with ten faculty members of Kermanshah University of Medical Sciences.The mean age of the participants was 21.34 (±1.43 years. 60.5% of them were females. 3.6% were freshmen and 49.9% were sophomores. 79.5% knew the goals before the start of clinical clerkship and 76.5% took part in the justification session in which their responsibility and method of evaluation were presented. 78.3% of them received the emergency protocol of Neurology.

    Qian, Xiaoyu

    Science is an area where a large achievement gap has been observed between White and minority, and between male and female students. The science minority gap has continued as indicated by the National Assessment of Educational Progress and the Trends in International Mathematics and Science Studies (TIMSS). TIMSS also shows a gender gap favoring males emerging at the eighth grade. Both gaps continue to be wider in the number of doctoral degrees and full professorships awarded (NSF, 2008). The current study investigated both minority and gender achievement gaps in science utilizing a multi-level differential item functioning (DIF) methodology (Kamata, 2001) within fully Bayesian framework. All dichotomously coded items from TIMSS 2007 science assessment at eighth grade were analyzed. Both gender DIF and minority DIF were studied. Multi-level models were employed to identify DIF items and sources of DIF at both student and teacher levels. The study found that several student variables were potential sources of achievement gaps. It was also found that gender DIF favoring male students was more noticeable in the content areas of physics and earth science than biology and chemistry. In terms of item type, the majority of these gender DIF items were multiple choice than constructed response items. Female students also performed less well on items requiring visual-spatial ability. Minority students performed significantly worse on physics and earth science items as well. A higher percentage of minority DIF items in earth science and biology were constructed response than multiple choice items, indicating that literacy may be the cause of minority DIF. Three-level model results suggested that some teacher variables may be the cause of DIF variations from teacher to teacher. It is essential for both middle school science teachers and science educators to find instructional methods that work more effectively to improve science achievement of both female and minority students

  10. The effect of science-technology-society issue instruction on the attitudes of female middle school students toward science

    Science.gov (United States)

    Mullinnix, Debra Lynn

    An assessment of the science education programs of the last thirty years reveals traditional science courses are producing student who have negative attitudes toward science, do not compete successfully in international science and mathematics competitions, are not scientifically literate, and are not interested in pursuing higher-level science courses. When the number of intellectually-capable females that fall into this group is considered, the picture is very disturbing. Berryman (1983) and Kahle (1985) have suggested the importance of attitude both, in terms of achievement in science and intention to pursue high-level science courses. Studies of attitudes toward science reveal that the decline in attitudes during grades four through eight was much more dramatic for females than for males. There exists a need, therefore, to explore alternative methods of teaching science, particularly in the middle school, that would increase scientific literacy, improve attitudes toward science, and encourage participation in higher-level science courses of female students. Yager (1996) has suggested that science-technology-society (STS) issue instruction does make significant changes in students' attitudes toward science, stimulates growth in science process skills, and increases concept mastery. The purpose of this study was to examine the effect STS issue instruction had on the attitudes of female middle school students toward science in comparison to female middle school students who experience traditional science instruction. Another purpose was to examine the effect science-technology-society issue instruction had on the attitudes of female middle school students in comparison to male middle school students. The pretests and the posttests were analyzed to examine differences in ten domains: enjoyment of science class; usefulness of information learned in science class; usefulness of science skills; feelings about science class in general; attitudes about what took place

    Computer-assisted learning, including simulated experiments, has great potential to address the problem solving process which is a complex activity. It requires a highly structured approach in order to understand the use of simulations as an instructional device. This study is based on a computer simulation program, 'The Growth Curve of Microorganisms', which required tenth grade biology students to use problem solving skills whilst simultaneously manipulating three independent variables in one simulated experiment. The aims were to investigate the computer simulation's impact on students' academic achievement and on their mastery of science process skills in relation to their cognitive stages. The results indicate that the concrete and transition operational students in the experimental group achieved significantly higher academic achievement than their counterparts in the control group. The higher the cognitive operational stage, the higher students' achievement was, except in the control group where students in the concrete and transition operational stages did not differ. Girls achieved equally with the boys in the experimental group. Students' academic achievement may indicate the potential impact a computer simulation program can have, enabling students with low reasoning abilities to cope successfully with learning concepts and principles in science which require high cognitive skills.

    Fuller, Richard A; Lee, Jasmine R; Watson, James E M

    2014-12-01

    Conservation science is a crisis discipline in which the results of scientific enquiry must be made available quickly to those implementing management. We assessed the extent to which scientific research published since the year 2000 in 20 conservation science journals is publicly available. Of the 19,207 papers published, 1,667 (8.68%) are freely downloadable from an official repository. Moreover, only 938 papers (4.88%) meet the standard definition of open access in which material can be freely reused providing attribution to the authors is given. This compares poorly with a comparable set of 20 evolutionary biology journals, where 31.93% of papers are freely downloadable and 7.49% are open access. Seventeen of the 20 conservation journals offer an open access option, but fewer than 5% of the papers are available through open access. The cost of accessing the full body of conservation science runs into tens of thousands of dollars per year for institutional subscribers, and many conservation practitioners cannot access pay-per-view science through their workplace. However, important initiatives such as Research4Life are making science available to organizations in developing countries. We urge authors of conservation science to pay for open access on a per-article basis or to choose publication in open access journals, taking care to ensure the license allows reuse for any purpose providing attribution is given. Currently, it would cost $51 million to make all conservation science published since 2000 freely available by paying the open access fees currently levied to authors. Publishers of conservation journals might consider more cost effective models for open access and conservation-oriented organizations running journals could consider a broader range of options for open access to nonmembers such as sponsorship of open access via membership fees. © 2014 The Authors.

    Austin, Jennifer

    Gender differences in middle school science were examined utilizing a mixed-methods approach. The intrinsic and extrinsic experiences of male and female non-gifted high-achieving students were investigated through the administration of the CAIMI, student interviews, teacher questionnaires, observations, and document examination. Male and female students were selected from a rural Northeast Georgia school district based on their high performance and high growth during middle school science. Eighty-three percent of the student participants were white and 17% were Hispanic. Half of the male participants and one third of the female participants were eligible for free and reduced meals. Findings revealed that male participants were highly motivated, whereas female participants exhibited varying levels of motivation in science. Both male and female students identified similar instructional strategies as external factors that were beneficial to their success. Due to their selection by both genders, these instructional strategies were considered to be gender-neutral and thereby useful for inclusion within coeducational middle school science classrooms.

    In many science, technology, engineering, and mathematics disciplines, women are outperformed by men in test scores, jeopardizing their success in science-oriented courses and careers. The current study tested the effectiveness of a psychological intervention, called values affirmation, in reducing the gender achievement gap in a college-level introductory physics class. In this randomized double-blind study, 399 students either wrote about their most important values or not, twice at the beginning of the 15-week course. Values affirmation reduced the male-female performance and learning difference substantially and elevated women's modal grades from the C to B range. Benefits were strongest for women who tended to endorse the stereotype that men do better than women in physics. A brief psychological intervention may be a promising way to address the gender gap in science performance and learning.

  7. The Effects of Teacher Efficacy, Teacher Certification Route, Content Hours in the Sciences, Field-Based Experiences and Class Size on Middle School Student Achievement

    No Child Left Behind Act (NCLB) was signed into law in 2002 with the idea that all students, no matter the circumstances can learn and that highly qualified teachers should be present in every classrooms (United Stated Department of Education, 2011). The mandates of NCLB also forced states to begin measuring the progress of science proficiency beginning in 2007. The study determined the effects of teacher efficacy, the type of certification route taken by individuals, the number of content hours taken in the sciences, field-based experience and class size on middle school student achievement as measured by the 8th grade STAAR in a region located in South Texas. This data provides knowledge into the effect different teacher training methods have on secondary school science teacher efficacy in Texas and how it impacts student achievement. Additionally, the results of the study determined if traditional and alternative certification programs are equally effective in properly preparing science teachers for the classroom. The study described was a survey design comparing nonequivalent groups. The study utilized the Science Teaching Efficacy Belief Instrument (STEBI). A 25-item efficacy scale made up of two subscales, Personal Science Teaching Efficacy Belief (PSTE) and Science Teaching Outcome Expectancy (STOE) (Bayraktar, 2011). Once the survey was completed a 3-Way ANOVA, MANOVA, and Multiple Linear Regression were performed in SPSS to calculate the results. The results from the study indicated no significant difference between route of certification on student achievement, but a large effect size was reported, 17% of the variances in student achievement can be accounted for by route of certification. A MANOVA was conducted to assess the differences between number of science content hours on a linear combination of personal science teacher efficacy, science teaching outcome expectancy and total science teacher efficacy as measured by the STEBI. No significant

    The purpose of this study was to examine the multiple mediational roles of academic social comparison directions (upward academic social comparison and downward academic social comparison) on the relationships between achievement goal orientations (i.e., mastery goals, performance-approach goals, and performance-avoidance goals) and subjective well-being (SWB) in school (school satisfaction, school affect) in adolescent students in China. A total of 883 Chinese adolescent students (430 males; Mean age = 12.99) completed a multi-measure questionnaire. Structural equation modeling was used to examine the hypotheses. Results indicated that (1) mastery goal orientations and performance-approach goal orientations both showed a statistically significant, positive correlation with SWB in school whereas performance-avoidance goal orientations showed a statistically significant, negative correlation with SWB in school among adolescents; (2) upward academic social comparisons mediated the relation between the three types of achievement goal orientations (i.e., mastery goals, performance-approach goals, and performance-avoidance goals) and SWB in school; (3) downward academic social comparisons mediated the relation between mastery goal orientations and SWB in school as well as the relation between performance-avoidance goal orientations and SWB in school. The findings suggest possible important cultural differences in the antecedents of SWB in school in adolescent students in China compared to adolescent students in Western nations.

  14. Consideration of learning orientations as an application of achievement goals in evaluating life science majors in introductory physics

    2018-06-01

    When considering performing an Introductory Physics for Life Sciences course transformation for one's own institution, life science majors' achievement goals are a necessary consideration to ensure the pedagogical transformation will be effective. However, achievement goals are rarely an explicit consideration in physics education research topics such as metacognition. We investigate a sample population of 218 students in a first-semester introductory algebra-based physics course, drawn from 14 laboratory sections within six semesters of course sections, to determine the influence of achievement goals on life science majors' attitudes towards physics. Learning orientations that, respectively, pertain to mastery goals and performance goals, in addition to a learning orientation that does not report a performance goal, were recorded from students in the specific context of learning a problem-solving framework during an in-class exercise. Students' learning orientations, defined within the context of students' self-reported statements in the specific context of a problem-solving-related research-based course implementation, are compared to pre-post results on physics problem-solving items in a well-established attitudinal survey instrument, in order to establish the categories' validity. In addition, mastery-related and performance-related orientations appear to extend to overall pre-post attitudinal shifts, but not to force and motion concepts or to overall course grade, within the scope of an introductory physics course. There also appears to be differentiation regarding overall course performance within health science majors, but not within biology majors, in terms of learning orientations; however, health science majors generally appear to fare less well on all measurements in the study than do biology majors, regardless of learning orientations.

  15. Using the Learning Together Strategy to Affect Student Achievement in Physical Science

    Campbell, Manda D.

    Despite efforts mandated by national legislation, the state of Georgia has made little progress in improving Grade 5 students' standardized test scores in science, spurring the need for social change. The purpose of this quantitative causal-comparative study was to determine whether there was a significant difference in the student achievement in the conceptual understanding of science concepts in a classroom where the teacher applied the cooperative learning strategy, Learning Together, as compared to the classroom in which teacher-directed instruction was applied. The theories of positive social interdependence and social development, which posit that social interaction promotes cognitive gains, provided a framework for the study. A convenience sample of 38 students in Grade 5 participated in the 6-week study. Nineteen students received the cooperative learning strategy treatment, while 19 students did not. Pre- and post-tests were administered to students in both groups, and an analysis of variance was performed to examine differences between the 2 sample means. Results indicated that the group receiving the cooperative learning strategy scored significantly higher than did the control group receiving direct instruction. The experimental group also scored higher in vocabulary acquisition. Using the cooperative learning strategy of Learning Together could guide teachers' efforts to help students achieve excellent state-mandated test scores. Learning Together may be employed as a powerful teaching tool across grade levels and content areas, thus promoting positive gains in other state-mandated testing areas such as math, language arts, and social studies.

  16. Spatial cognition and science achievement: The contribution of intrinsic and extrinsic spatial skills from 7 to 11 years.

    Prior longitudinal and correlational research with adults and adolescents indicates that spatial ability is a predictor of science learning and achievement. However, there is little research to date with primary-school aged children that addresses this relationship. Understanding this association has the potential to inform curriculum design and support the development of early interventions. This study examined the relationship between primary-school children's spatial skills and their science achievement. Children aged 7-11 years (N = 123) completed a battery of five spatial tasks, based on a model of spatial ability in which skills fall along two dimensions: intrinsic-extrinsic; static-dynamic. Participants also completed a curriculum-based science assessment. Controlling for verbal ability and age, mental folding (intrinsic-dynamic spatial ability), and spatial scaling (extrinsic-static spatial ability) each emerged as unique predictors of overall science scores, with mental folding a stronger predictor than spatial scaling. These spatial skills combined accounted for 8% of the variance in science scores. When considered by scientific discipline, mental folding uniquely predicted both physics and biology scores, and spatial scaling accounted for additional variance in biology and variance in chemistry scores. The children's embedded figures task (intrinsic-static spatial ability) only accounted for variance in chemistry scores. The patterns of association were consistent across the age range. Spatial skills, particularly mental folding, spatial scaling, and disembedding, are predictive of 7- to 11-year-olds' science achievement. These skills make a similar contribution to performance for each age group. © 2018 The Authors.

H02: There will be no significant statistical association between the educational factors teacher certification type (composite or content specific) and teacher certification pathway and the percent passing rate of their tenth grade African American male students on the 2010 science TAKS. H03: There will be no significant statistical association between a teachers' demographic factors, educational factors and the percent passing rate of their tenth grade African American male students on the 2010 science TAKS. The researcher employed the assistance of the human resource departments of participating districts to generate a demographic report identifying the sex, years of experience, certification types and pathways of the teachers of record for African American male students who took the 10th grade Science TAKS during the 2009-2010 school year. Data ascertained from the demographic report was entered in the Statistical Package for the Social Sciences Software (SPSS). A linear regression statistical analysis was used to establish the following: 1). the degree of association between demographic factors and the percent passing rate of their African American male students on the 10th grade science TAKS , 2) the degree of association between educational factors and the percent passing rate of their African American male students on the 10th grade science TAKS, 3) the degree of association between demographic and educational factors and the percent passing rate of their African American male students on the 10th grade science TAKS Conclusion: Constantine et al (2009) concluded that although individual teachers appear to have an effect on student achievement, their study could not identify what about a teacher affects student achievement. Similar to Constatine, the researcher did not find any association between the demographic and educational factors of teachers and the science academic achievement of African American males

  19. Science self-efficacy of African American middle school students: Relationship to motivation self-beliefs, achievement, gender, and gender orientation

    Britner, Shari Lynn

    Motivation researchers have established that students' self-efficacy beliefs, the confidence they have in their academic capabilities, are related to academic outcomes. Self-efficacy has been amply researched in mathematics and language arts and nearly exclusively with White students. African American students and the area of science have each received scant attention. Typically, gender differences favor boys in mathematics and girls in language arts. Researchers have also found that these differences may be a function of gender orientation beliefs. The purpose of this study was to extend findings in science self-efficacy and to African American middle school students. I sought to determine whether self-efficacy assessed at differing levels of specificity (lab skills versus science grades) would each predict science achievement assessed at corresponding levels, to discover whether mean scores in academic motivation and achievement would differ by gender, and to determine whether these differences are a function of gender orientation (N = 268). Science grade self-efficacy was positively associated with the grades obtained by boys and by girls. For girls, grades were also associated positively with science self-concept and negatively with value of science. For reasons resulting from problematic instructional practices, lab skills self-efficacy was not associated with lab grades. Girls reported stronger science self-efficacy and received higher grades in science class. Gender orientation beliefs did not account for these differences, but masculinity and femininity were each associated with science grade self-efficacy, suggesting that androgyny is an adaptive orientation for the science self-efficacy beliefs of African American students. Findings are interpreted within the framework of A. Bandura's (1986) social cognitive theory.

    2013-01-01

    There are many barriers to using science to inform conservation policy and practice. Conservation scientists wishing to produce management-relevant science must balance this goal with the imperative of demonstrating novelty and rigor in their science. Decision makers seeking to make evidence-based decisions must balance a desire for knowledge with the need to act despite uncertainty. Generating science that will effectively inform management decisions requires that the production of information (the components of knowledge) be salient (relevant and timely), credible (authoritative, believable, and trusted), and legitimate (developed via a process that considers the values and perspectives of all relevant actors) in the eyes of both researchers and decision makers. We perceive 3 key challenges for those hoping to generate conservation science that achieves all 3 of these information characteristics. First, scientific and management audiences can have contrasting perceptions about the salience of research. Second, the pursuit of scientific credibility can come at the cost of salience and legitimacy in the eyes of decision makers, and, third, different actors can have conflicting views about what constitutes legitimate information. We highlight 4 institutional frameworks that can facilitate science that will inform management: boundary organizations (environmental organizations that span the boundary between science and management), research scientists embedded in resource management agencies, formal links between decision makers and scientists at research-focused institutions, and training programs for conservation professionals. Although these are not the only approaches to generating boundary-spanning science, nor are they mutually exclusive, they provide mechanisms for promoting communication, translation, and mediation across the knowledge–action boundary. We believe that despite the challenges, conservation science should strive to be a boundary science, which

    Murrah, William M., III

    The achievement score gaps between advantaged and disadvantaged children at school entry is a major problem in education today. Identifying the skills critical for school readiness is an important step in developing interventions aimed at addressing these score gaps. The purpose of this study is to compare a number of school readiness skills with an eye toward finding out which are the best predictors of later academic achievement in math, reading, and science. The predictors were early reading, math, general knowledge, socioemotional skills, and motor skills. Data were obtained from the Early Childhood Longitudinal Study of 1998 (NCES, 1998) database. While controlling for an extensive set of family characteristics, predictions were made across five years - from the end of kindergarten to the end of fifth grade. Consistent with current findings, reading and math skills predicted later achievement. Interestingly, general knowledge, attention, and fine motor skills also proved to be important predictors of later academic achievement, but socioemotional skills were not. The findings were interpreted from a neurobiological perspective involving the development of self-regulation. These school entry skills are used to predict later achievement in reading, math, and science. I argued that in addition to acquiring early academic knowledge, children need to regulate the use of this knowledge to meet academic goals.

The program includes video role-model stories featuring minority scientists and students, hands-on activities, and teacher resources. Collaborators from The University of Texas Health Science Center at Houston, Spring Branch Independent School District, and the Health Museum developed the modules. From 2004 to 2007, the authors used a quasi-experimental, two-group pretest/posttest design to assess program effects on students' performance and interest in science, their science self-efficacy, their fear of science, and their science-related careers self-efficacy. An independent third party matched the intervention school to a comparison school by test scores, school demographics, and student demographics and then matched pairs of sixth-grade students (N = 428) by fifth-grade science scores, gender, ethnicity, and participation in the free or reduced lunch program. The authors collected data on these students for three years. At eighth grade (2007), the intervention school students scored significantly higher (F = 12.38, P science and reported higher interest in science (F = 11.08, P school pairs. Students in neither group reported an increase in their confidence to choose a science-related career, but students in one high-implementing teacher's class reported decreased fear of science. HEADS UP shows potential for improving inner-city, non-Asian-minority middle school students' performance and interest in science.

    The purpose of this study was to examine the multiple mediational roles of academic social comparison directions (upward academic social comparison and downward academic social comparison) on the relationships between achievement goal orientations (i.e., mastery goals, performance-approach goals, and performance-avoidance goals) and subjective well-being (SWB) in school (school satisfaction, school affect) in adolescent students in China. A total of 883 Chinese adolescent students (430 males; Mean age = 12.99) completed a multi-measure questionnaire. Structural equation modeling was used to examine the hypotheses. Results indicated that (1) mastery goal orientations and performance-approach goal orientations both showed a statistically significant, positive correlation with SWB in school whereas performance-avoidance goal orientations showed a statistically significant, negative correlation with SWB in school among adolescents; (2) upward academic social comparisons mediated the relation between the three types of achievement goal orientations (i.e., mastery goals, performance-approach goals, and performance-avoidance goals) and SWB in school; (3) downward academic social comparisons mediated the relation between mastery goal orientations and SWB in school as well as the relation between performance-avoidance goal orientations and SWB in school. The findings suggest possible important cultural differences in the antecedents of SWB in school in adolescent students in China compared to adolescent students in Western nations. PMID:28197109

    Students' motivational beliefs about learning physical science are critical for achieving positive educational outcomes. In this study, we incorporated expectancy-value theory to capture the heterogeneity of adolescents' motivational trajectories in physics and chemistry from seventh to twelfth grade and linked these trajectories to science-related outcomes. We used a cross-sequential design based on three different cohorts of adolescents (N = 699; 51.5 % female; 95 % European American; M ages for youngest, middle, and oldest cohorts at the first wave = 13.2, 14.1, and 15.3 years) coming from ten public secondary schools. Although many studies claim that physical science motivation declines on average over time, we identified seven differential motivational trajectories of ability self-concept and task values, and found associations of these trajectories with science achievement, advanced science course taking, and science career aspirations. Adolescents' ability self-concept and task values in physics and chemistry were also positively related and interlinked over time. Examining how students' motivational beliefs about physical science develop in secondary school offers insight into the capacity of different groups of students to successfully adapt to their changing educational environments.

    Estrada, Myrna Hipol

    In light of the need to close the achievement gap among our culturally and linguistically diverse students, more specifically the Hispanics and the Hispanic English Learners (ELs), the effects of teacher professional development (2 year PD vs. 1 Year PD vs. no PD) on the implementation of a standards-aligned and inquiry-based science curriculum program---the Integrated Coordinated Science for the 21st Century published by It's About Time, Inc. (ICS-IAT)---on the LAUSD ninth graders science scores were examined. Participants included 8,937 9th grade students (7,356 Hispanics). The primary outcome measurement was scaled scores from the California Standard Test (CST) in Integrated Coordinated Science (CST_ICS1). Correlations between California English Language Development Test (CELDT) component subscores (reading, listening and speaking) and CST scores were also examined. Results indicated that the science scores of the students of teachers who participated in two year PD were significantly higher compared to the scores of students of the one year PD group and the control group. The results show that all ethnic groups benefited from two years of teacher PD, except the African American group. Among Hispanics, students classified as IFEP, RFEP and EO gained from the teachers having two years of professional development. But the target population, ELs did not benefit from two years of teacher PD. The correlations between the CELDT and CST_ELA were much higher than the CELDT and CST_ICS1 correlations. This finding validates Abedi's claim (2004) that EL students are disadvantaged because of their language handicap on tests that have a greater language load. Two year PD participation significantly enhanced the accessibility of science to the ninth graders. The essential features in the PD were classroom simulation of all the activities identified in the storyboard with the actual and correct use of needed equipment and materials; creation and presentation of sample or model

    Full Text Available A new scientometric indicator, the h-index, has been recently proposed (Hirsch JE. Proc Natl Acad Sci 2005; 102: 16569-16572. The index avoids some shortcomings of the calculation of the total number of citations as a parameter to evaluate scientific performance. Although it has become known only recently, it has had widespread acceptance. A comparison of the average h-index of members of the Brazilian Academy of Sciences (BAS and of the National Academy of Sciences of the USA (NAS-USA was carried out for 10 different areas of science. Although, as expected, the comparison was unfavorable to the members of the BAS, the imbalance was distinct in different areas. Since these two academies represent, to a significant extent, the science of top quality produced in each country, the comparison allows the identification of the areas in Brazil that are closer to the international stakeholders of scientific excellence. The areas of Physics and Mathematics stand out in this context. The heterogeneity of the h-index in the different areas, estimated by the median dispersion of the index, is significantly higher in the BAS than in the NAS-USA. No elements have been collected in the present study to provide an explanation for this fact.

    2017-03-01

    Full Text Available Abstract Background Large-scale cross-national studies designed to measure student achievement use different social, cultural, economic and other background variables to explain observed differences in that achievement. Prior to their inclusion into a prediction model, these variables are commonly scaled into latent background indices. To allow cross-national comparisons of the latent indices, measurement invariance is assumed. However, it is unclear whether the assumption of measurement invariance has some influence on the results of the prediction model, thus challenging the reliability and validity of cross-national comparisons of predicted results. Methods To establish the effect size attributed to different degrees of measurement invariance, we rescaled the ‘home resource for learning index’ (HRL for the 37 countries ( $$n=166,709$$ n = 166 , 709 students that participated in the IEA’s combined ‘Progress in International Reading Literacy Study’ (PIRLS and ‘Trends in International Mathematics and Science Study’ (TIMSS assessments of 2011. We used (a two different measurement models [one-parameter model (1PL and two-parameter model (2PL] with (b two different degrees of measurement invariance, resulting in four different models. We introduced the different HRL indices as predictors in a generalized linear mixed model (GLMM with mathematics achievement as the dependent variable. We then compared three outcomes across countries and by scaling model: (1 the differing fit-values of the measurement models, (2 the estimated discrimination parameters, and (3 the estimated regression coefficients. Results The least restrictive measurement model fitted the data best, and the degree of assumed measurement invariance of the HRL indices influenced the random effects of the GLMM in all but one country. For one-third of the countries, the fixed effects of the GLMM also related to the degree of assumed measurement invariance. Conclusion The

    Full Text Available Introduction: Learning style is an individual’s preferred method of encountering information in specific situations in order to acquire knowledge, skills and attitudes through study or experience. Students and Planers’ awareness of learning styles facilitate the teaching process, increases satisfaction and makes the future choices easier. This study aimed to examine different learning styles and their relation to academic achievement in medical students of basic sciences program at Tabriz University of Medical Sciences. Methods: In this descriptive – analytical study, the sample consisted of all medical students of basic sciences program at Tabriz University of Medical Sciences in 2011-2012. The data was collected through a questionnaire which included respondents’ demographic information and overall grade point average (GPA as well as Kolb standard questions on learning styles. Results: 4.3%, 47.8%, 44.9% and 2.9% of students preferred diverger, assimilator, converger and accommodator learning styles, respectively. Mean overall GPA of students who preferred diverger learning styles was 14.990.39±. Students who prefer assimilator, converger and accommodator learning styles had mean overall GPAs of 14.940.56±, 15.080.58± and 14.830.29± respectively. The findings showed no significant relationship between students’ learning academic achievement and their learning styles (p = 0.689. Conclusion: There was no significant relationship between Students’ academic achievement and their learning styles. Furthermore, the majorit of the students preferred accommodator and converger learning styles. Consequently, adopting interactive teaching methods, using tutorials, running simulation programs, launching laboratory activities and encouraging students to think and analyze problems and issues can be greatly effective in prolonging their learning lifecycle.

    Wildland fire management has reached a crossroads. Current perspectives are not capable of answering interdisciplinary adaptation and mitigation challenges posed by increases in wildfire risk to human populations and the need to reintegrate fire as a vital landscape process. Fire science has been, and continues to be, performed in isolated "silos," including institutions (e.g., agencies versus universities), organizational structures (e.g., federal agency mandates versus local and state procedures for responding to fire), and research foci (e.g., physical science, natural science, and social science). These silos tend to promote research, management, and policy that focus only on targeted aspects of the "wicked" wildfire problem. In this article, we provide guiding principles to bridge diverse fire science efforts to advance an integrated agenda of wildfire research that can help overcome disciplinary silos and provide insight on how to build fire-resilient communities.

    Sevensma, Kara

    In today's digital world the Internet is becoming an increasingly predominant resource for science information, rapidly eclipsing the traditional science textbook in content area classrooms (Lawless & Schrader, 2008). The shift challenges researchers, educators, administrators, and policy makers to reconsider what it means to read and comprehend online science information. The research on digital literacy is still in its infancy and little is known about the strategies and processes students use when reading science content on the Internet. Even less is known about how at-risk readers comprehend digital science content. Therefore, this study addresses three research questions: (1) What strategies and processes do at-risk and average-achieving readers use as they locate information and generate meaning from science websites? (2) What navigational profiles emerge as at-risk and average-achieving readers construct traversals (unique online paths of information) they locate information and generate meaning from science websites? (3) What individual characteristics influenced students' strategies as they locate information and generate meaning from science websites? Participants were six ninth-grade students in general education biology classrooms. Three were average-achieving readers and three were at-risk readers based on assessments of reading comprehension in traditional print-based texts. The students engaged in a three-day research project about the rainforest biome, locating information online, taking notes, and constructing an information brochure about the rainforest for peers. Data measures prior to and during the research included an Internet use survey, verbal protocols, screen captures of online activity, oral reading fluency assessments, and prior knowledge and topic engagement surveys. Quantitative descriptive and univariate analyses as well as qualitative abductive coding were employed over multiple phases to analyze the data. First, the results suggest

    Eason, Grace Teresa

    The purpose of this quasi-experimental study was to determine the effect a higher-order questioning strategy (Bloom, 1956) had on undergraduate non-science majors' attitudes toward the environment and their achievement in an introductory environmental science course, EDS 1032, "Survey of Science 2: Life Science," which was offered during the Spring 2000 term. Students from both treatment and control groups (N = 63), which were determined using intact classes, participated in eight cooperative group activities based on the Biological Sciences Curriculum Studies (BSCS) 5E model (Bybee, 1993). The treatment group received a higher-order questioning method combined with the BSCS 5E model. The control group received a lower-order questioning method, combined with the BSCS 5E model. Two instruments were used to measure students' attitude and achievement changes. The Ecology Issue Attitude (EIA) survey (Schindler, 1995) and a comprehensive environmental science final exam. Kolb's Learning Style Inventory (KLSI, 1985) was used to measure students' learning style type. After a 15-week treatment period, results were analyzed using MANCOVA. The overall MANCOVA model used to test the statistical difference between the collective influences of the independent variables on the three dependent variables simultaneously was found to be not significant at alpha = .05. This differs from findings of previous studies in which higher-order questioning techniques had a significant effect on student achievement (King 1989 & 1992; Blosser, 1991; Redfield and Rousseau, 1981; Gall 1970). At the risk of inflated Type I and Type II error rates, separate univariate analyses were performed. However, none of the research factors, when examined collectively or separately, made any significant contribution to explaining the variability in EIA attitude, EIA achievement, and comprehensive environmental science final examination scores. Nevertheless, anecdotal evidence from student's self

    Telfer, Jo Ann

    Science has become an essential part of our cultural, social and technological lives. Around the world economic policies are giving high priority to the production of new knowledge generated by scientists. Unfortunately, gender equality in science-related careers has not been achieved. Women who possess high intellectual and personal abilities are succeeding in many occupational areas previously closed to all but the most impervious women, but females are still largely underrepresented in physical science and mathematics related careers. The purpose of the current study was to examine the reasons for this underrepresentation of women in science-related careers. Participants included a subset of mothers (n = 174), fathers (n = 132) and children (n = 186) from a larger study at the University of Calgary entitled Gender Differences in Student Participation and Achievement in the Sciences: Choice or Chance ? Telephone interview and survey questionnaire data were examined for gender and achievement level differences, focusing on high achieving girls who are most likely to succeed in science-related careers. Relationships between parents' and children's responses were also examined using the theoretical construct of Eccles' Model of Achievement Related Choices. Gathered data were studied using factor analysis, multivariate analysis of variance, analysis of variance as well as categorical analysis of qualitative results. Girls and boys achieved similar grades on all academic measures except the Alberta Science Achievement Test, where boys scored significantly higher than girls. Mothers, fathers, and children indicated positive attitudes towards science, no gender stereotyping about science and science careers, and gender neutral beliefs about science achievement. Gender differences were found in expressed possibility of future career choice. Science/Professional Careers were viewed as male occupations by mothers and children, but as gender neutral occupations by fathers

    The purpose of this researcher was to examine specific environmental, educational, and demographic factors and their influence on mathematics and science achievement. In particular, the researcher ascertained the interconnections of home computer access and social capital, with Asian American students and the effect on mathematics and science achievement. Coleman's theory on social capital and parental influence was used as a basis for the analysis of data. Subjects for this study were the base year students from the National Education Longitudinal Study of 1988 (NELS:88) and the subsequent follow-up survey data in 1990, 1992, and 1994. The approximate sample size for this study is 640 ethnic Asians from the NELS:88 database. The analysis was a longitudinal study based on the Student and Parent Base Year responses and the Second Follow-up survey of 1992, when the subjects were in 12th grade. Achievement test results from the NELS:88 data were used to measure achievement in mathematics and science. The NELS:88 test battery was developed to measure both individual status and a student's growth in a number of achievement areas. The subject's responses were analyzed by principal components factor analysis, weights, effect sizes, hierarchial regression analysis, and PLSPath Analysis. The results of this study were that prior ability in mathematics and science is a major influence in the student's educational achievement. Findings from the study support the view that home computer access has a negative direct effect on mathematics and science achievement for both Asian American males and females. None of the social capital factors in the study had either a negative or positive direct effect on mathematics and science achievement although some indirect effects were found. Suggestions were made toward increasing parental involvement in their children's academic endeavors. Computer access in the home should be considered related to television viewing and should be closely

    The scale anchoring method was used to analyze and describe the TIMSS primary and middle school (Populations 1 and 2) mathematics and science achievement scales. Scale anchoring is a way of attaching meaning to a scale by describing what students know and can do at specific points on the scale. Student achievement was scrutinized at four points on the TIMSS primary and middle school achievement scales---the 25th, 50th, 75th, and 90th international percentiles for fourth and eighth grades. The scale anchoring method was adapted for the TIMSS data and items that students scoring at each of the four scale points were likely to answer correctly (with a 65 percent probability) were identified. The items were assembled in binders organized by anchor level and content area. Two ten-member panels of subject-matter specialists were convened to scrutinize the items, draft descriptions of student proficiency at the four scale points, and identify example TIMSS items to illustrate performance at each level. Following the panel meetings, the descriptions were refined through an iterative review process. The result is a content-referenced interpretation of the TIMSS scales through which TIMSS achievement results can be better communicated and understood.

    Ellwood, Robin B.

    This research investigated how student social interactions within two approaches to an inquiry-based science curriculum could be related to student motivation and achievement outcomes. This qualitative case study consisted of two cases, Off-Campus and On-Campus, and used ethnographic techniques of participant observation. Research participants included eight eighth grade girls, aged thirteen to fourteen years old. Data sources included formal and informal participant interviews, participant journal reflections, curriculum artifacts including quizzes, worksheets, and student-generated research posters, digital video and audio recordings, photographs, and researcher field notes. Data were transcribed verbatim and coded, then collapsed into emergent themes using NVIVO 9. The results of this research illustrate how setting conditions that promote focused concentration and communicative interactions can be positively related to student motivation and achievement outcomes in inquiry-based science. Participants in the Off-Campus case experienced more frequent states of focused concentration and out performed their peers in the On-Campus case on forty-six percent of classroom assignments. Off-Campus participants also designed and implemented a more cognitively complex research project, provided more in-depth analyses of their research results, and expanded their perceptions of what it means to act like a scientist to a greater extent than participants in the On-Campus case. These results can be understood in relation to Flow Theory. Student interactions that promoted the criteria necessary for initiating flow, which included having clearly defined goals, receiving immediate feedback, and maintaining a balance between challenges and skills, fostered enhanced student motivation and achievement outcomes. This research also illustrates the positive gains in motivation and achievement outcomes that emerge from student experiences with extended time in isolated areas referred to

  19. Students' Preference for Science Careers: International comparisons based on PISA 2006

    Kjærnsli, Marit; Lie, Svein

    2011-01-01

    This article deals with 15-year-old students' tendencies to consider a future science-related career. Two aspects have been the focus of our investigation. The first is based on the construct called 'future science orientation', an affective construct consisting of four Likert scale items that measure students' consideration of being involved in future education and careers in science-related areas. Due to the well-known evidence for Likert scales providing culturally biased estimates, the aim has been to go beyond the comparison of simple country averages. In a series of regression and correlation analyses, we have investigated how well the variance of this construct in each of the participating countries can be accounted for by other Programme for International Student Assessment (PISA) student data. The second aspect is based on a question about students' future jobs. By separating science-related jobs into what we have called 'soft' and 'hard' science-related types of jobs, we have calculated and compared country percentages within each category. In particular, gender differences are discussed, and interesting international patterns have been identified. The results in this article have been reported not only for individual countries, but also for groups of countries. These cluster analyses of countries are based on item-by-item patterns of (residual values of) national average values for the combination of cognitive and affective items. The emerging cluster structure of countries has turned out to contribute to the literature of similarities and differences between countries and the factors behind the country clustering both in science education and more generally.

  20. Innovative science within and against a culture of achievement

    2003-05-01

    As science educators struggle to reform science education, we need a better understanding of the conundrums associated with the ways educators enact innovative science within and against the academic, rigorous, and elite sociohistorical constructions of science. I ethnographically investigated the meanings of an innovative, reform-based curriculum (Active Physics) in various micro (classroom) and macro (school and community) contexts. I conducted the study in a high school serving primarily upper middle class students, the majority of whom (97%) planned to attend college. I explored how meanings of the curriculum transformed as the curriculum traveled across space and time. While certain aspects of the context enabled innovative science (e.g., support from the administration, pressure to serve a wider range of students), other aspects of the context constrained the potential of the curriculum (e.g., the need to establish for students, parents, and administrators the legitimacy of Active Physics as real and rigorous physics). Using practice theory to understand the influence of context and agency in shaping school science practice, this study demonstrates the potential for viewing meanings of science in local settings as partially fluid entities, sometimes reproducing and sometimes contesting sociohistorical legacies.

  1. Facilitating interest and out-of-school engagement in science in secondary school girls: Increasing the effectiveness of the teaching for transformative experience in science model through parental involvement

    Heddy, Benjamin Charles

    This study investigated the impact of adding a parental involvement intervention to the Teaching for Transformative Experience in Science (TTES) model in science courses (biology and chemistry) in an all-girl middle and high school (N = 89). Specifically, the goal was to increase out-of-school engagement, interest, parental involvement, and achievement. Analysis showed that TTES with the addition of a parent intervention (TTES+PI) facilitated more out-of-school engagement and parent involvement than a comparison. Furthermore, a high initial level of situational and individual interest was maintained in the TTES+PI condition; whereas both forms of interest decreased in the comparison. A content analysis of transformative experience journal entries suggested that when parents showed value for science concepts, students' experiential value increased. The results provide evidence that the addition of a parent intervention may increase the effectiveness of TTES and maintain girl's interest in science, which has theoretical and practical implications.

    Full Text Available Disparities in educational outcomes exist between students in rural areas as compared to students in urban settings. While there is some evidence that these rural disparities are present in eastern Europe, little is known about young peoples’ lives in the rural areas of this region. This paper presents an analysis of science achievement by location (rural v. urban using all available waves of the Trends in International Mathematics and Science Study (TIMSS. We examined the eighth grade data from five countries: Lithuania, Romania, the Russian Federation, Hungary, and Slovenia. Findings demonstrated that students attending rural schools had significantly lower science scores and that the rural disadvantage grew between 1995 and 2011 in some countries, but became non-significant in others. Overall, family socioeconomic status played an important role in determining the educational outcomes of rural students. The implications of these findings are explored in relation to the United Nations Educational, Scientific and Cultural Organization (UNESCO 2015 Education for All goals.

    Friend, Jennifer Ingrid

    This study examined two hypotheses related to same-gender grouping of eighth-grade science classes in a public middle-school setting in suburban Kansas City. The first hypothesis, male and female students enrolled in same-gender eighth-grade science classes demonstrate more positive science academic achievement than their male and female peers enrolled in mixed-gender science classes. The second hypothesis, same-gender grouping of students in eighth-grade science has a positive effect on classroom climate. The participants in this study were randomly assigned to class sections of eighth-grade science. The first experimental group was an eighth-grade science class of all-male students (n = 20) taught by a male science teacher. The control group used for comparison to the male same-gender class consisted of the male students (n = 42) in the coeducational eighth-grade science classes taught by the same male teacher. The second experimental group was an eighth-grade science class of all-female students (n = 23) taught by a female science teacher. The control group for the female same-gender class consisted of female students (n = 61) in the coeducational eighth-grade science classes taught by the same female teacher. The male teacher and the female teacher did not vary instruction for the same-gender and mixed-gender classes. Science academic achievement was measured for both groups through a quantitative analysis using grades on science classroom assessment and overall science course grades. Classroom climate was measured through qualitative observations and through qualitative and quantitative analysis of a twenty-question student survey administered at the end of each trimester grading period. The results of this study did not indicate support for either hypothesis. Data led to the conclusions that same-gender grouping did not produce significant differences in student science academic achievement, and that same-gender classes did not create a more positive

  9. SciDB versus Spark: A Preliminary Comparison Based on an Earth Science Use Case

    2015-12-01

    We compare two Big Data technologies, SciDB and Spark, for performance, usability, and extensibility, when applied to a representative Earth science use case. SciDB is a new-generation parallel distributed database management system (DBMS) based on the array data model that is capable of handling multidimensional arrays efficiently but requires lengthy data ingest prior to analysis, whereas Spark is a fast and general engine for large scale data processing that can immediately process raw data files and thereby avoid the ingest process. Once data have been ingested, SciDB is very efficient in database operations such as subsetting. Spark, on the other hand, provides greater flexibility by supporting a wide variety of high-level tools including DBMS's. For the performance aspect of this preliminary comparison, we configure Spark to operate directly on text or binary data files and thereby limit the need for additional tools. Arguably, a more appropriate comparison would involve exploring other configurations of Spark which exploit supported high-level tools, but that is beyond our current resources. To make the comparison as "fair" as possible, we export the arrays produced by SciDB into text files (or converting them to binary files) for the intake by Spark and thereby avoid any additional file processing penalties. The Earth science use case selected for this comparison is the identification and tracking of snowstorms in the NASA Modern Era Retrospective-analysis for Research and Applications (MERRA) reanalysis data. The identification portion of the use case is to flag all grid cells of the MERRA high-resolution hourly data that satisfies our criteria for snowstorm, whereas the tracking portion connects flagged cells adjacent in time and space to form a snowstorm episode. We will report the results of our comparisons at this presentation.

    2016-12-01

    Full Text Available Women’s participation in science, technology, engineering and mathematics (STEM courses and careers lags behind that of men. Multiple factors contribute to the underrepresentation of women and girls in STEM. Academic research suggests three areas, which account for the under representation of girls in STEM: social and environmental factors, the school climate and the influence of bias. In order to engage and to retain girls in STEM, educators need to: eliminate bias in the classroom, change school culture, introduce female role models, help girls assess their abilities accurately and develop talent in areas related to science, technology, engineering, and mathematics. Educators should encourage young girls to ask questions about the world, to problem solve, and to develop creativity through play and experimentation. Women have made impressive gains in science and engineering but remain a distinct minority in many science and engineering fields. Creating environments that support girls’ and women’s achievements and interests in science and engineering will encourage more girls and women to pursue careers in these vital fields.

    Dionisio, Rui Meira

    The randomized research study assessed the effect of an inquiry-based science (IBS) program on non-cognitive outcomes and academic achievement. The study was the result of a grant that was awarded by Professional Resources in Science and Mathematics (PRISM), a program affiliated with Montclair State University in conjunction with Bristol-Myers Squibb, and part of the New Jersey Statewide Systemic Initiative (NJSSI). The NJSSI is a partnership of schools, districts, colleges and universities, science centers, businesses, and museums dedicated to improving the teaching and learning of science, mathematics, and technology in New Jersey. The quantitative research study utilized an IBS instructional program titled Science and Technology Concepts for Middle Schools (STC/MS) and was implemented in two middle schools within the same suburban school district. This study examined the effect of IBS classrooms on learning outcomes specifically related to gender and special education. Evaluation of student learning outcomes was conducted through the administration of three instruments: the Academic Self-Concept (ASC) scale, unit assessments, and NJASK 8 Science. The ASC scale and unit assessments were administered as a pretest and posttest in IBS classrooms. NJASK 8 Science scale scores were obtained through reporting of student performance data from the New Jersey Department of Education to the district. The quantitative analysis in this study provided evidence that IBS classrooms had a positive effect on academic achievement. Overall, students in IBS classrooms performed better than students in traditional classrooms on unit assessments. Additionally, male students and special education students in IBS classrooms outperformed students in traditional classrooms on unit assessments.

    Elementary and secondary students spend more hours outside of class than in formal school and thus have more time for interaction with everyday science. However, evidence from a large international survey, Program of International Student Assessment (PISA) (OECD 2012), found a negative relationship between number of hours attending after-school science and science assessment scores in many countries, raising questions about why. The secondary analysis of the 2006, 2009, and 2012 PISA surveys found that in most Western countries the longer students attended after-school science programs (in a typical week), the lower their PISA standardized science test score, but the higher their positive attitudes toward future science careers, interest in science, and self-confidence in science. Several potential hypotheses for this relationship are examined and rejected. Further analysis of a causal relationship between frequent attendance in after-school programs and student achievement and attitudes should clearly identify the content of the program so that the analysis could distinguish experiences closely related to regular school curricula from the informal science activities that are not. A new analysis also should include carefully designed longitudinal surveys to test the effectiveness of informal experiences on later life choices in career and study.

    Full Text Available In this study, I examined academic achievement of immigrant children in the United States, Canada, England, Australia, and New Zealand. Analyzing data from the Third International Mathematics and Science Study (TIMSS, I gauged the performance gaps relating to the generation of immigration and the home language background. I found immigrant children's math and science achievement to be lower than the others only in England, the U.S., and Canada. Non-English language background was found in each country to relate to poor math and science learning and this disadvantage was stronger among native-born children—presumably children of indigenous groups—than among immigrant children. I also examined the school variation in math performance gaps, using hierarchical linear modeling (HLM to each country's data. The patterns in which language- and generation-related math achievement gaps varied between schools are different in the five countries.

    2014-01-01

    Conservation science is a crisis discipline in which the results of scientific enquiry must be made available quickly to those implementing management. We assessed the extent to which scientific research published since the year 2000 in 20 conservation science journals is publicly available. Of the 19,207 papers published, 1,667 (8.68%) are freely downloadable from an official repository. Moreover, only 938 papers (4.88%) meet the standard definition of open access in which material can be freely reused providing attribution to the authors is given. This compares poorly with a comparable set of 20 evolutionary biology journals, where 31.93% of papers are freely downloadable and 7.49% are open access. Seventeen of the 20 conservation journals offer an open access option, but fewer than 5% of the papers are available through open access. The cost of accessing the full body of conservation science runs into tens of thousands of dollars per year for institutional subscribers, and many conservation practitioners cannot access pay-per-view science through their workplace. However, important initiatives such as Research4Life are making science available to organizations in developing countries. We urge authors of conservation science to pay for open access on a per-article basis or to choose publication in open access journals, taking care to ensure the license allows reuse for any purpose providing attribution is given. Currently, it would cost $51 million to make all conservation science published since 2000 freely available by paying the open access fees currently levied to authors. Publishers of conservation journals might consider more cost effective models for open access and conservation-oriented organizations running journals could consider a broader range of options for open access to nonmembers such as sponsorship of open access via membership fees.

    Over the last few decades research in the natural sciences has unveiled a number of specific complex relations between human activity an environmental change on a global scale. Scientific assesment confirm that global life support systems, such as climate, biodiversity and water resources are significantly affected by human activities. System change became the key in the research plan that emerged - systems being defined as the socio-economic and technical chains of production, distribution, consumption and disposal activities. Predicting the impact of a changing world on human health is a hard task and requires an interdisciplinary approach drawn from the fields of evaluation, biogeography, ecology and social sciences, and relying on various methodologies such as mathematical modelling as well as historical analysis. However, the great majority of public health researchers are empiricists by training and tradition, studying the past and the present via direct observation. By definition empirical methods cannot be used to study the future. To extent that the advent of global environmental changes obliges scientists to estimate future impacts, should current or foreseeable trends continue, then empiricism must be supplemented by integrated assessment modelling. The prediction of environmental change and its health impacts encounters uncertainties at various level. Some of the uncertainties are of scientific kind or are referring to the conceptualisation and construction of mathematical models where the specification of linked processes may be uncertain. Research on transformation towards sustainability puts emphasis on the interaction of innovation (production), consumption and institution and incentive structure. The specific challenges and research needs are: - Understand the dynamics of structural change in sociotechno-ecological system and anticipate transformation paths (knowledge of system dynamics); - Assess and evaluate the impacts of specific paths of

    Several methods of transverse patellar fixation have been described. This study compares the clinical outcome and the occurrence of complications of various fixation methods. The databases PubMed, Web of Science, Science Direct, Google Scholar and Google were searched. A direct comparison between fixation techniques using mixed or non-metallic implants and metallic K-wire and tension band fixation shows no significant difference in clinical outcome between both groups. Additionally, studies reporting novel operation techniques show good clinical results. Studies describing the treatment of patients using non-metallic or mixed implants are fewer compared with those using metallic fixation. A large variety of clinical scoring systems were used for assessing the results of treatment, which makes direct comparison difficult. More data of fracture treatment using non-metallic or mixed implants is needed to achieve a more balanced comparison.

In the past 25 years, the contribution of the NAS to the gross agricultural production in China was up to 250 hundred millions yuan RMB, corresponding to the ratio of 1:31 of integrated scientific investments to the output. Comparison was made between the development of NAS in China and that abroad. Present situation and the prospect of the NAS were also discussed. (1 fig.; 5 tabs.)

    The 6-yr degree-completion rate of undergraduate science, technology, engineering, and mathematics (STEM) majors at U.S. colleges and universities is less than 40%. Persistence among women and underrepresented minorities (URMs), including African-American, Latino/a, Native American, and Pacific Islander students, is even more troubling, as these students leave STEM majors at significantly higher rates than their non-URM peers. This study utilizes a matched comparison group design to examine the academic achievement and persistence of students enrolled in the Program for Excellence in Education and Research in the Sciences (PEERS), an academic support program at the University of California, Los Angeles, for first- and second-year science majors from underrepresented backgrounds. Results indicate that PEERS students, on average, earned higher grades in most "gatekeeper" chemistry and math courses, had a higher cumulative grade point average, completed more science courses, and persisted in a science major at significantly higher rates than the comparison group. With its holistic approach focused on academics, counseling, creating a supportive community, and exposure to research, the PEERS program serves as an excellent model for universities interested in and committed to improving persistence of underrepresented science majors and closing the achievement gap. © 2015 B.

    Future space science missions developed to achieve the most ambitious goals are likely to be complex, large, publicly and professionally very important, and at the limit of affordability. Consequently, it may be valuable if such missions can be upgraded, repaired, and/or deployed in space, either with robots or with astronauts. In response to a Request for Information from the US National Research Council panel on Science Opportunities Enabled by NASA's Constellation System, we developed a concept for astronaut-based in-space servicing at the Earth-Moon L1,2 locations that may be implemented by using elements of NASA's Constellation architecture. This libration point jobsite could be of great value for major heliospheric and astronomy missions operating at Earth-Sun Lagrange points. We explored five alternative servicing options that plausibly would be available within about a decade. We highlight one that we believe is both the least costly and most efficiently uses Constellation hardware that appears to be available by mid-next decade: the Ares I launch vehicle, Orion/Crew Exploration Vehicle, Centaur vehicle, and an airlock/servicing node developed for lunar surface operations. Our concept may be considered similar to the Apollo 8 mission: a valuable exercise before descent by astronauts to the lunar surface.

    The FP7 IMPEx infrastructure, whose general goal is to encourage and facilitate inter-comparison between observational and model data in planetary plasma sciences, is now established for 2 years. This presentation will focus on a tour of the different achievements which occurred during this period. Within the project, data originate from multiple sources : large observational databases (CDAWeb, AMDA at CDPP, CLWeb at IRAP), simulation databases for hybrid and MHD codes (FMI, LATMOS), planetary magnetic field models database and online services (SINP). Each of these databases proposes dedicated access to their models and runs (HWA@FMI, LATHYS@LATMOS, SMDC@SINP). To gather this large data ensemble, IMPEx offers a distributed framework in which these data may be visualized, analyzed, and shared thanks to interoperable tools; they comprise of AMDA - an online space physics analysis tool -, 3DView - a tool for data visualization in 3D planetary context -, and CLWeb - an online space physics visualization tool. A simulation data model, based on SPASE, has been designed to ease data exchange within the infrastructure. On the communication point of view, the VO paradigm has been retained and the architecture is based on web services and the IVOA protocol SAMP. The presentation will focus on how the tools may be operated synchronously to manipulate these heterogeneous data sets. Use cases based on in-flight missions and associated model runs will be proposed for the demonstration. Finally the motivation and functionalities of the future IMPEx portal will be exposed. As requirements to and potentialities of joining the IMPEx infrastructure will be shown, the presentation could be seen as an invitation to other modeling teams in the community which may be interested to promote their results via IMPEx.

  13. A study of the effects of gender and different instructional media (computer-assisted instruction tutorials vs. textbook) on student attitudes and achievement in a team-taught integrated science class

    Eardley, Julie Anne

    The purpose of this study was to determine the effect of different instructional media (computer assisted instruction (CAI) tutorial vs. traditional textbook) on student attitudes toward science and computers and achievement scores in a team-taught integrated science course, ENS 1001, "The Whole Earth Course," which was offered at Florida Institute of Technology during the Fall 2000 term. The effect of gender on student attitudes toward science and computers and achievement scores was also investigated. This study employed a randomized pretest-posttest control group experimental research design with a sample of 30 students (12 males and 18 females). Students had registered for weekly lab sessions that accompanied the course and had been randomly assigned to the treatment or control group. The treatment group used a CAI tutorial for completing homework assignments and the control group used the required textbook for completing homework assignments. The Attitude toward Science and Computers Questionnaire and Achievement Test were the two instruments administered during this study to measure students' attitudes and achievement score changes. A multivariate analysis of covariance (MANCOVA), using hierarchical multiple regression/correlation (MRC), was employed to determine: (1) treatment versus control group attitude and achievement differences; and (2) male versus female attitude and achievement differences. The differences between the treatment group's and control group's homework averages were determined by t test analyses. The overall MANCOVA model was found to be significant at p factor set independent variables separately resulted in gender being the only variable that significantly contributed in explaining the variability in a dependent variable, attitudes toward science and computers. T test analyses of the homework averages showed no significant differences. Contradictory to the findings of this study, anecdotal information from personal communication, course

    Davis, Consuella Artiemese

    This study investigated predictors that influence the science achievement of African-American non-science majors in a Physical Science class. The population consisted of male and female college students enrolled in Physical Science courses at a historical black college or university (HBCU) located in the southeastern portion of the United States. A personal data information sheet was administered to 120 participants during the Fall of 2008. The personal data information sheet consisted of questions pertaining to the high school courses, students took in math, language arts and science. It also consisted of basic background information. Students also gave written consent for their midterm and final grades earned in Physical Science to be used in the study as part of the analyses. A t-Test including chi-square tests revealed that there was not a significant difference in the raw scores of African-American females and African American males on the American College Test. A significant difference was not observed between the females and males on the ACT math subtest, t (118) = -.78, p = .43; reading comprehension subtest, t (118) = -1.44, .15 or on the science reasoning subtest, t (118) = -1.46, p = .15. A significant difference was not found between the final grades of African American females and the final grades of African American males. Chi-square tests were conducted to determine goodness of fit, X2 = 6.11, df = 1, p = .191. Although the grades of females were higher than males, results were not significant. The correlation between math ACT and final grades were not significant, r = .131, N = 120, p = .155, reading comprehension ACT and final grades were not significant, r = .072, N = 120, p = .434 and science reasoning ACT and final grades were found not to be significant, r = .109, N = 120, p = .237. Being that the majority of students who participated in the study were from one state, had similar high school backgrounds, had similar majors and were similar in

    Scientific achievement by publishing a scientific manuscript in a peer reviewed biomedical journal is an important ingredient of research along with a career-enhancing advantages and significant amount of personal satisfaction. The road to evaluate science (research, scientific publications) among scientists often seems complicated. Scientist's career is generally summarized by the number of publications / citations, teaching the undergraduate, graduate and post-doctoral students, writing or reviewing grants and papers, preparing for and organizing meetings, participating in collaborations and conferences, advising colleagues, and serving on editorial boards of scientific journals. Scientists have been sizing up their colleagues since science began. Scientometricians have invented a wide variety of algorithms called science metrics to evaluate science. Many of the science metrics are even unknown to the everyday scientist. Unfortunately, there is no all-in-one metric. Each of them has its own strength, limitation and scope. Some of them are mistakenly applied to evaluate individuals, and each is surrounded by a cloud of variants designed to help them apply across different scientific fields or different career stages [1]. A suitable indicator should be chosen by considering the purpose of the evaluation, and how the results will be used. Scientific Evaluation assists us in: computing the research performance, comparison with peers, forecasting the growth, identifying the excellence in research, citation ranking, finding the influence of research, measuring the productivity, making policy decisions, securing funds for research and spotting trends. Key concepts in science metrics are output and impact. Evaluation of science is traditionally expressed in terms of citation counts. Although most of the science metrics are based on citation counts but two most commonly used are impact factor [2] and h-index [3].

  17. The Emergent Capabilities of Distributed Satellites and Methods for Selecting Distributed Satellite Science Missions

    Science.gov (United States)

    Corbin, B. A.; Seager, S.; Ross, A.; Hoffman, J.

    2017-12-01

    Distributed satellite systems (DSS) have emerged as an effective and cheap way to conduct space science, thanks to advances in the small satellite industry. However, relatively few space science missions have utilized multiple assets to achieve their primary scientific goals. Previous research on methods for evaluating mission concepts designs have shown that distributed systems are rarely competitive with monolithic systems, partially because it is difficult to quantify the added value of DSSs over monolithic systems. Comparatively little research has focused on how DSSs can be used to achieve new, fundamental space science goals that cannot be achieved with monolithic systems or how to choose a design from a larger possible tradespace of options. There are seven emergent capabilities of distributed satellites: shared sampling, simultaneous sampling, self-sampling, census sampling, stacked sampling, staged sampling, and sacrifice sampling. These capabilities are either fundamentally, analytically, or operationally unique in their application to distributed science missions, and they can be leveraged to achieve science goals that are either impossible or difficult and costly to achieve with monolithic systems. The Responsive Systems Comparison (RSC) method combines Multi-Attribute Tradespace Exploration with Epoch-Era Analysis to examine benefits, costs, and flexible options in complex systems over the mission lifecycle. Modifications to the RSC method as it exists in previously published literature were made in order to more accurately characterize how value is derived from space science missions. New metrics help rank designs by the value derived over their entire mission lifecycle and show more accurate cumulative value distributions. The RSC method was applied to four case study science missions that leveraged the emergent capabilities of distributed satellites to achieve their primary science goals. In all four case studies, RSC showed how scientific value was

  18. One-to-one iPad technology in the middle school mathematics and science classrooms

    Science.gov (United States)

    Bixler, Sharon G.

    Science, technology, engineering, and mathematics (STEM) education has become an emphasized component of PreK-12 education in the United States. The US is struggling to produce enough science, mathematics, and technology experts to meet its national and global needs, and the mean scores of science and mathematics students are not meeting the expected levels desired by our leaders (Hossain & Robinson, 2011). In an effort to improve achievement scores in mathematics and science, school districts must consider many components that can contribute to the development of a classroom where students are engaged and growing academically. Computer technology (CT) for student use is a popular avenue for school districts to pursue in their goal to attain higher achievement. The purpose of this study is to examine the use of iPads in a one-to-one setting, where every student has his own device 24/7, to determine the effects, if any, on academic achievement in the areas of mathematics and science. This comparison study used hierarchical linear modeling (HLM) to examine three middle schools in a private school district. Two of the schools have implemented a one-to-one iPad program with their sixth through eighth grades and the third school uses computers on limited occasions in the classroom and in a computer lab setting. The questions addressed were what effect, if any, do the implementation of a one-to-one iPad program and a teacher's perception of his use of constructivist teaching strategies have on student academic achievement in the mathematics and science middle school classrooms. The research showed that although the program helped promote the use of constructivist activities through the use of technology, the one-to-one iPad initiative had no effect on academic achievement in the middle school mathematics and science classrooms.

    Research experience programs engage teachers in the hands-on practice of science. Program advocates assert that program participation enhances teachers' skills in communicating science to students. We measured the impact of New York City public high-school science teachers' participation in Columbia University's Summer Research Program on their students' academic performance in science. In the year before program entry, students of participating and nonparticipating teachers passed a New York State Regents science examination at the same rate. In years three and four after program entry, participating teachers' students passed Regents science exams at a rate that was 10.1% higher (P = 0.049) than that of nonparticipating teachers' students. Other program benefits include decreased teacher attrition from classroom teaching and school cost savings of U.S. $1.14 per $1 invested in the program.

  7. The supplemental instruction program: Student perceptions of the learning environment and impact on student academic achievement in college science at California State University, San Marcos

    Hizer, Suzanne Elizabeth

    Higher education in science has been criticized and calls to increase student learning and persistence to degree has been recognized as a national problem by the Department of Education, the National Science Foundation, the National Research Council, and the National Academy of Sciences. One mode of academic assistance that may directly address this issue is the implementation of Supplemental Instruction (SI) in science courses. SI is a specific model of academic assistance designed to help students in historically difficult science classes master course content, thus increasing their academic achievement and retention. This study assessed the SI program at California State University, San Marcos, in supported science courses. Specifically, academic achievement based on final course grades were compared between SI participating and nonparticipating students, multiple affective factors were measured at the beginning and end of the semester, and students' perceptions of the classroom and SI session learning environments recorded. Overall, students who attended five or more SI sessions achieved higher final course grades. Students who chose to participate in SI had higher initial levels of responsibility and anxiety. Additionally, SI participants experienced a reduction in anxiety over the semester whereas nonparticipants experienced an increase in anxiety from beginning to the end of the semester. The learning environment of SI embodies higher levels of constructivist principles of active learning such as cooperation, cohesiveness, innovation, and personalization---with one exception for the physics course, which is a based on problem-based learning. Structural equation modeling of variables indicates that high self-efficacy at the end of the semester is directly related to high final course grades; this is mediated by cohesion in the classroom and the cooperation evidenced in SI sessions. These findings are elaborated by student descriptions of what happened in SI

    2013-05-01

    Due to the scarcity of cross-cultural comparative studies in exploring students' self-efficacy in science learning, this study attempted to develop a multi-dimensional science learning self-efficacy (SLSE) instrument to measure 316 Singaporean and 303 Taiwanese eighth graders' SLSE and further to examine the differences between the two student groups. Moreover, within-culture comparisons were made in terms of gender. The results showed that, first, the SLSE instrument was valid and reliable for measuring the Singaporean and Taiwanese students' SLSE. Second, through a two-way multivariate analysis of variance analysis (nationality by gender), the main result indicated that the SLSE held by the Singaporean eighth graders was significantly higher than that of their Taiwanese counterparts in all dimensions, including 'conceptual understanding and higher-order cognitive skills', 'practical work (PW)', 'everyday application', and 'science communication'. In addition, the within-culture gender comparisons indicated that the male Singaporean students tended to possess higher SLSE than the female students did in all SLSE dimensions except for the 'PW' dimension. However, no gender differences were found in the Taiwanese sample. The findings unraveled in this study were interpreted from a socio-cultural perspective in terms of the curriculum differences, societal expectations of science education, and educational policies in Singapore and Taiwan.

    This year-long, quasi-experimental study investigated the impact of the use of netbook computers and interactive science software on fifth-grade students' science learning processes, academic achievement, and interest in further science, technology, engineering, and mathematics (STEM) study within a linguistically diverse school district in California. Analysis of students' state standardized science test scores indicated that the program helped close gaps in scientific achievement between at-risk learners (i.e., English learners, Hispanics, and free/reduced-lunch recipients) and their counterparts. Teacher and student interviews and classroom observations suggested that computer-supported visual representations and interactions supported diverse learners' scientific understanding and inquiry and enabled more individualized and differentiated instruction. Finally, interviews revealed that the program had a positive impact on students' motivation in science and on their interest in pursuing science-related careers. This study suggests that technology-facilitated science instruction is beneficial for improving at-risk students' science achievement, scaffolding students' scientific understanding, and strengthening students' motivation to pursue STEM-related careers.

  13. Gender roles and science beliefs and their relationship to science interest

    Science.gov (United States)

    Paolucci, Judith Jean

    This study investigated adolescents' views about the nature of science (NOS) and conceptions of their gender identities, and revealed whether these conceptions and views are related to their science interest. Participants were 566 high school students enrolled in chemistry courses at three high schools in a New England state. A questionnaire was used to assess participants' science interest, gender role perceptions, and views about science, as well as to provide background and math and science achievement data. The study found that while student scores of NOS understanding did not differ by gender, some significant differences were noted on the student responses to statements about science. Students with higher-than-average science interest scores responded to these statements differently than students with lower science interest scores; their responses tended to more closely match statements about NOS taken from current reform documents. The study also found that math and science achievement, masculinity scores, and NOS scores accounted for a greater variance of science interest for girls than for boys, though all three also contributed significantly and positively to the regression equation for boys. These predictor variables predicted membership to the lower or higher science interest groups, but could not predict students' career aspiration groups. Thus, other mediating factors not considered in this study may translate high science interest to science career aspiration. The results of this study coed prior research, which found that science and math achievement and masculinity are positively and significantly related to science interest for boy boys and girls. Moreover, the study found that achievement in math and science courses is a greater predictor of science interest for girls than for boys. The results of this study provide a rationale for incorporating the nature of science into the science curriculum. Moreover, since the science interest of boys was

Many at risk students have poor attendance, are disengaged from the learning environment and have low academic achievement. Educational failure occurs when students do not complete the required courses and as a result do not receive a high school diploma or a certificate of attendance. Many at risk students will not graduate; nearly one-third of all United States high school students have left the public school system before graduating, which has been referred to as a national crisis. Many at risk students fail science courses that are required for graduation, such as biology. Clearly, many students are not responding positively to the conditions in many public school classrooms, suggesting the need for different methods of educating at risk students, such as e-education. Three research questions guided the study: 1) Who are the students in an e-education, online summer school credit recovery course? 2) Do students' beliefs about their learning environment or other personal factors influence their academic achievement?, and 3) How do students describe their experiences of an e-education science course? This mixed methods study investigates thirty-two at risk students who were enrolled in one of three e-education science education courses (biology, earth science, and physical science) during a summer session in a rural county in a southeastern US state. These students failed their most recent science course taken in a traditional classroom setting. Artino's (2010) social-cognitive model of academic motivation and emotion was used as a theoretical framework to highlight the salient motivational factors toward learning science (e.g., task characteristics, task value beliefs, positive emotions). Student data included pre and post tests for all e-education lessons, a final exam, survey data (Students Motivation towards Science Learning (SMTSL), time (on task and idle), field notes, and

    Cavagnetto, Andy Roy

    This study was conducted to determine the effects of two different student-centered approaches to setting the question for inquiry. The first approach (whole class) consisted of students setting a single question for inquiry after which students worked in small groups during an investigation phase of the activity with all groups exploring the same question. The second approach (small group) consisted of each group of students setting a question resulting in numerous questions being explored per class. A mixed method quasi-experimental design was utilized. Two grade five teachers from a small rural school district in the Midwestern United States participated, each teaching two sections of science (approximately 25 students per section). Results indicate three major findings. Instructional approach (whole class vs. small group) did not effect student achievement in science or language arts. Observational data indicated the actions and skills teachers utilized to implement the approaches were similar. Specifically, the pedagogical skills of dialogical interaction (which was found to be influenced by teacher level of control of learning and teacher content knowledge) and effective rather than efficient use of time were identified as key factors in teachers' progression toward a student-centered, teacher-managed instructional approach. Unit exams along with qualitative and quantitative teacher observation data indicated that these factors do have an impact on student achievement. Specifically increased dialogical interaction in the forms of greater student voice, and increased cognitive demands placed on students by embedding and emphasizing science argument within the student inquiry corresponded to positive gains in student achievement. Additionally, teacher's perception of student abilities was also found to influence professional growth. Finally, allowing students to set the questions for inquiry and design the experiments impact the classroom environment as teacher

    The purpose of this study is to examine the effect of two strategies for negotiating the question for exploration during science inquiry on student achievement and teachers' perceptions. The study is set in the context of the Science Writing Heuristic. The first strategy (small group) consisted of each group of four students negotiating a question for inquiry with the teacher while the second strategy (whole class) consisted of the entire class negotiating a single question for inquiry with the teacher. The study utilized a mixed-method approach. A quasi-experimental repeated measures design was used to determine the effect of strategy on student achievement and semi-structured teacher interviews were used to probe the question of teacher perceptions of the two strategies. Teacher observations were conducted using the Reformed Teaching Observation Protocol (RTOP) to check for variation in implementation of the two strategies. Iowa Test of Basic Skills Science (ITBSS) (2005 and 2006) and teacher/researcher developed unit exams (pre and post) were used as student achievement measures. No statistically significant differences were found among students in the two treatment groups on the ITBSS or unit exams. RTOP observations suggest that teacher implementation was consistent across the two treatment strategies. Teachers disclosed personal preferences for the two strategies, indicating the whole class treatment was easier to manage (at least at the beginning of the school year) as students gained experience with science inquiry and the associated increased responsibility. Possible mechanisms linking the two strategies, negotiated questions, and student outcomes are discussed.

    2015-08-01

    Full Text Available By using TIMSS Grade 4 2011 science data for Serbia and Slovenia, this study examined which of two dimensions towards science learning (self-confidence in learning science, or liking learning science, if any, was primarily related to students' cognitive achievement in science. This achievement was considered for three cognitive domains, namely: Knowing, Applying, and Reasoning. The analysis revealed that, in both countries, achievement was mainly linked to self-confidence in each of the three cognitive domains. Because of positive correlations, classroom work may be improved by including, whenever possible, activities aimed at strengthening students' beliefs in their own abilities to learn science.

  20. The origin of oil and gas in light of the latest achievements in earth sciences

    1984-01-01

    A theory of mineralogical asthenospheric origin of oil and gas is justified from geological, geophysical and geochemical standpoints in light of the contemporary achievements of earth sciences. The conditions of formation of oil and gas bearing provinces and the formation of oil and gas deposits are characterized. Three eras of oil and gas formation and oil and gas accumulation in the earth's crust, which are associated with the Hercynian, Cimmerian and Alpine geotectonic cycles of development of geosynclinal regions, are identified in the evolutionary development of the earth. The presented opinions are supported by data from geological exploration practice and by current materials from hydrogeochemistry, thermobarogeologeochemistry, space geochemistry and from the study of volcanos.

    Chung-Schickler, Genevieve C.

    The purpose of this study was to evaluate the effect of cooperative learning strategies on students' attitudes toward science and achievement in BSC 1005L, a non-science majors' general biology laboratory course at an urban community college. Data were gathered on the participants' attitudes toward science and cognitive biology level pre and post treatment in BSC 1005L. Elements of the Learning Together model developed by Johnson and Johnson and the Student Team-Achievement Divisions model created by Slavin were incorporated into the experimental sections of BSC 1005L. Four sections of BSC 1005L participated in this study. Participants were enrolled in the 1998 spring (January) term. Students met weekly in a two hour laboratory session. The treatment was administered to the experimental group over a ten week period. A quasi-experimental pretest-posttest control group design was used. Students in the cooperative learning group (nsb1 = 27) were administered the Test of Science-Related Attitudes (TOSRA) and the cognitive biology test at the same time as the control group (nsb2 = 19) (at the beginning and end of the term). Statistical analyses confirmed that both groups were equivalent regarding ethnicity, gender, college grade point average and number of absences. Independent sample t-tests performed on pretest mean scores indicated no significant differences in the TOSRA scale two or biology knowledge between the cooperative learning group and the control group. The scores of TOSRA scales: one, three, four, five, six, and seven were significantly lower in the cooperative learning group. Independent sample t-tests of the mean score differences did not show any significant differences in posttest attitudes toward science or biology knowledge between the two groups. Paired t-tests did not indicate any significant differences on the TOSRA or biology knowledge within the cooperative learning group. Paired t-tests did show significant differences within the control group

    Shoop, Kathleen A.

    Drawing on socio-cognitive learning theory, this study compared achievement scores of 134 male and female high school biology students randomly assigned to groups which either used self-reflection, used self-reflection and received feedback, or did not self-reflect. Following a pretest, the teacher provided self-reflection strategy instruction to students in the two intervention groups and then subsequently provided in-class self-reflection time for these groups. The posttest concluded the unit; the retention measure was five weeks later. A quasi-experimental 3 x 3 x 2 (time x intervention x gender) factorial repeated-measures control group design was used for this study; a repeated measures ANOVA and several one-way ANOVA's were used to answer the research questions. Results from the repeated-measures ANOVA revealed significant results for Time and Time x Intervention, with the reflection group demonstrating significantly lower gains from pretest to posttest than the other two groups. The ANOVA examining differences between those who reflected and those who reflected and received feedback provided significant results with similar results for the difference between the control group and the reflection group. For teachers and students this study provides several areas of practical significance. Primarily, teachers may find lower student achievement if students regularly self-reflect but do not receive feedback for their reflection.

    Full Text Available It has been critical to find a way for teachers to motivate their young children to learn science and improve science achievement. Since music has been used as a tool for educating young students, this study introduces the science song project to teacher candidates that contains science facts, concepts, laws and theories, and combines them with music for motivating their young children to learn science and improve science achievement. The purpose of the study is to determine the effect of the science song project on teacher candidates’ understanding of science processing skills and their attitudes toward science. The participants were 45 science teacher candidates who were enrolled in an EC-6 (Early Childhood through Grade 6 program in the teacher certification program at a racially diverse Texas public research university. To collect data, this study used two instruments: pre-and post-self efficacy tests before and after the science teacher candidates experienced the science song project and final reflective essay at the end of the semester. The results show that while developing their songs, the participating teacher candidates experienced a process for science practice, understood science concepts and facts, and positively improved attitudes toward science. This study suggests that the science song project is a science instruction offering rich experiences of process-based learning and positive attitudes toward science.

    established East and Southeast Asian Federation of Soil Science Societies (ESAFS) in 1991. Since the early 1990s the research topics have become more related to the global as well as regional environmental issues. Major achievements in the history of the society may include 1) development of research particularly on paddy soils and volcanic ash soils, 2) consistent commitment to the education for constructing sustainable society, and 3) international cooperation in improving rice production in the developing countries particularly in Tropical Asia. Today 2,699 members are registered in the society, which includes 9 divisions and holds an annual meeting every year. Two journals are bimonthly published, i.e. "Japanese Journal of Soil Science and Plant Nutrition" in Japanese and "SSPN" in English and the latter was recognized as a cooperating journal of IUSS in 2010. Future challenges of the society are 1) more commitment to international organizations, e.g. EGU in addition to IUSS, ESAFS and other soil-based communities, 2) enhancement of international cooperation for developing countries not only in Asia but also Africa, and 3) acceleration of soils research and education in association with related disciplines for constructing a holistically harmonized society on the planet earth.

    1997-08-01

    The purpose of this investigation was to determine if an integrated curriculum in algebra 1/physical science facilitates acquisition of proportional reasoning and graphing abilities better than a non-integrated, traditional, algebra 1 curriculum. Also, this study was to ascertain if the integrated algebra 1/physical science curriculum resulted in greater student achievement in algebra 1. The curriculum used in the experimental class was SAM 9 (Science and Mathematics 9), an investigation-based curriculum that was written to integrate physical science and basic algebra content. The experiment was conducted over one school year. The subjects in the study were 61 ninth grade students. The experimental group consisted of one class taught concurrently by a mathematics teacher and a physical science teacher. The control group consisted of three classes of algebra 1 students taught by one mathematics teacher and taking physical science with other teachers in the school who were not participating in the SAM 9 program. This study utilized a quasi-experimental non-randomized control group pretest-posttest design. The investigator obtained end-of-algebra 1 scores from student records. The written open-ended graphing instruments and the proportional reasoning instrument were administered to both groups as pretests and posttests. The graphing instruments were also administered as a midtest. A two sample t-test for independent means was used to determine significant differences in achievement on the end-of-course algebra 1 test. Quantitative data from the proportional reasoning and graphing instruments were analyzed using a repeated measures analysis of variance to determine differences in scores over time for the experimental and control groups. The findings indicate no significant difference between the experimental and control groups on the end-of-course algebra 1 test. Results also indicate no significant differences in proportional reasoning and graphing abilities between

    Mazzie, Dawn Danielle

    This study investigated the relationship between students' standardized test scores in science and (a) increases in teacher assessment literacy and (b) teacher participation in a Teacher Quality Research (TQR) project on classroom assessment. The samples for these studies were teachers from underperforming schools who volunteered to take part in a professional development program in classroom assessment. School groups were randomly assigned to the treatment group. For Study 1, teachers in the treatment received professional development in classroom assessment from a trained assessment coach. Teachers in the control received no professional development. For Study 2, teachers in Treatment 1 received professional development in classroom assessment from a trained assessment coach and teachers in Treatment 2 received professional development in classroom assessment from a facilitator with one day of training. Teachers in both groups completed a measure of assessment literacy, the Teacher Quality Research Test of Assessment Literacy Skills (TQR_TALS), prior to the beginning and then again at the conclusion of the four month professional development program. A hierarchical linear model (HLM) analysis was conducted to determine the relationship between students' standardized test scores in science and (a) increases in teacher assessment literacy and (b) teacher TQR status. Based upon these analyses, the professional development program increased teachers' assessment literacy skills; however, the professional development had no significant impact on students' achievement.

    Dutra, Andrew Martin

    The purpose of this study was to determine the relationship of specific attributes of college students to their academic achievement at an independent university in central Florida. Academic achievement was measured as the numeric score on the final exam in a survey-of-science course (EDS 1032) required for non-science majors. Attribute sets included personological, affective, and fitness variables. A hypothesized diagram of the direct and indirect effects among these attributes relative to academic achievement was developed and tested using data collected Spring 2014 from 168 students in four sections of EDS 1032 at Florida Institute of Technology. Multiple regression results revealed that 19% of the variance in a students' academic achievement was due to the influence of these three sets of research factors; this was found to be statistically significant. The results of mediation analyses also indicated that three variables had significant direct effects on academic achievement, namely gender, number of academic credits, and sports motivation. In addition, gender had a significant indirect effect on academic achievement via stress, and the number of academic credits had a significant indirect effect on academic achievement via sports motivation. These findings indicated that female students scored roughly six points higher than male students on this final exam. Also, gender's influence on academic achievement was partially attributable to the student's level of stress (e.g., male students with high levels of stress had lower grades on this final exam than female students with the same level of stress). In addition, it was found that students taking more academic credits were likely to score higher on this final exam than those students taking fewer credits. Further, as students' level of sports amotivation increased, the strength of the relationship between the number of student academic credits and academic achievement decreased. These results support Self

    An experimental and interview-based design was used to test the efficacy of visual thinking networking (VTN), a new generation of metacognitive learning strategies. Students constructed network diagrams using semantic and figural elements to represent knowledge relationships. The findings indicated the importance of using color in VTN strategies. The use of color promoted the encoding and reconstruction of earth science knowledge in memory and enhanced higher order thinking skills of problem solving. Fifty-six ninth grade earth science students (13--15 years of age) in a suburban school district outside New York City were randomly assigned to three classes with the same instructor. Five major positive findings emerged in the areas of problem solving achievement, organization of knowledge in memory, problem solving strategy dimensionality, conceptual understanding, and gender differences. A multi-covariate analysis was conducted on the pre-post gain scores of the AGI/NSTA Earth Science Examination (Part 1). Students who used the color VTN strategies had a significantly higher mean gain score on the problem solving criterion test items than students who used the black/white VTN (p = .003) and the writing strategies for learning science (p color VTN strategies: (1) significantly recalled more earth science knowledge than students who used the black/white VTN (p = .021) and the writing strategies (p color VTNs had a significantly higher mean number of conceptually accurate propositions than students who used the black/white VTN (p = .018) and the writing strategies (p = .010). Gender influenced the choice of VTN strategy. Females used significantly more color VTN strategies, while males used predominately black/white VTN strategies (p = .01). A neurocognitive model, the encoding activation theory of the anterior cingulate (ENACT-AC), is proposed as an explanation for these findings.

    2014-01-01

    Summary Amid ongoing public speculation about the reasons for sex differences in careers in science and mathematics, we present a consensus statement that is based on the best available scientific evidence. Sex differences in science and math achievement and ability are smaller for the mid-range of the abilities distribution than they are for those with the highest levels of achievement and ability. Males are more variable on most measures of quantitative and visuospatial ability, which necessarily results in more males at both high- and low-ability extremes; the reasons why males are often more variable remain elusive. Successful careers in math and science require many types of cognitive abilities. Females tend to excel in verbal abilities, with large differences between females and males found when assessments include writing samples. High-level achievement in science and math requires the ability to communicate effectively and comprehend abstract ideas, so the female advantage in writing should be helpful in all academic domains. Males outperform females on most measures of visuospatial abilities, which have been implicated as contributing to sex differences on standardized exams in mathematics and science. An evolutionary account of sex differences in mathematics and science supports the conclusion that, although sex differences in math and science performance have not directly evolved, they could be indirectly related to differences in interests and specific brain and cognitive systems. We review the brain basis for sex differences in science and mathematics, describe consistent effects, and identify numerous possible correlates. Experience alters brain structures and functioning, so causal statements about brain differences and success in math and science are circular. A wide range of sociocultural forces contribute to sex differences in mathematics and science achievement and ability—including the effects of family, neighborhood, peer, and school

    Full Text Available Introduction: Social networks are the most important means of communication in the societies as well as in the world, so the use of virtual social networks among students is important. The purpose of this study was to evaluate the use of virtual social networks among students in Gonabad University of Medical Sciences. Methods: In this descriptive study, 277 students were randomly selected from  Gonabad University of  Medical Sciences. They completed a questionnaire which its validity and reliability were obtained in earlier studies. Then the data were analyzed using SPSS software version 20. Results: The findings showed that 87 percent of the students were aware of virtual social networks, and 52 percent were members of these social networks. Students spend about an hour and eleven minutes (SD=2.20771 on the virtual networks. There was no significant difference between academic achievement of students in the groups. Conclusion: The results showed that more than half of the students were members of social networks. Students are not familiar with all of the effects of these social networks since they are recently emerged, so performing more research on other aspects of their impact on the life and health of students are necessary.

  20. Can citizen science enhance public understanding of science?

    Bonney, Rick; Phillips, Tina B; Ballard, Heidi L; Enck, Jody W

    2016-01-01

    Over the past 20 years, thousands of citizen science projects engaging millions of participants in collecting and/or processing data have sprung up around the world. Here we review documented outcomes from four categories of citizen science projects which are defined by the nature of the activities in which their participants engage - Data Collection, Data Processing, Curriculum-based, and Community Science. We find strong evidence that scientific outcomes of citizen science are well documented, particularly for Data Collection and Data Processing projects. We find limited but growing evidence that citizen science projects achieve participant gains in knowledge about science knowledge and process, increase public awareness of the diversity of scientific research, and provide deeper meaning to participants' hobbies. We also find some evidence that citizen science can contribute positively to social well-being by influencing the questions that are being addressed and by giving people a voice in local environmental decision making. While not all citizen science projects are intended to achieve a greater degree of public understanding of science, social change, or improved science -society relationships, those projects that do require effort and resources in four main categories: (1) project design, (2) outcomes measurement, (3) engagement of new audiences, and (4) new directions for research. © The Author(s) 2015.

  1. An analysis of science conceptual knowledge in journals of students with disabilities and normally achieving students

    Grigg, Gail S.

    Science education reforms of the last two decades have focused on raising the bar for ALL students which includes students with mild to moderate disabilities. Formative assessment can be used to assess the progress of these students to inquire, understand scientific concepts, reason scientifically, make decisions, and communicate effectively in science. The purpose of this study is to examine the use of science journals as a formative assessment in a guided inquiry unit of study for students with learning disabilities. Two normally achieving students (NA) and five students with learning disabilities (SLD) participated in a study of mammals that utilized journals to record the development of student knowledge through the course of study. Students were interviewed after the lessons were complete using the same prompts required in the journals. Themes were developed from the student writings and their verbal discourse using Grounded Theory. Journals and verbal discourse were rated following the themes of Knowledge Telling (KT) and Knowledge Transformation (KTR). Concept maps were developed for the Pre and Post test lessons (written and verbal discourses) by the raters in an attempt to further explain the knowledge that the students conveyed. The results of this study suggest that SLD are able to demonstrate knowledge about mammals better through verbal discourse than written discourse. While the NA students wrote more and used more technical discourse than did their SLD peers, the conceptual understanding of the topic by the SLD was no less inclusive than their NA peers when accessed verbally. The journals demonstrated limited conceptual growth for the SLD. Further, while lexical density is important to the development of knowledge in science, this study suggests the "conceptual density" may be another important indicator to examine.

  7. The effect of playing a science center-based mobile game: Affective outcomes and gender differences

    Science.gov (United States)

    Atwood-Blaine, Dana

    Situated in a hands-on science center, The Great STEM Caper was a collaborative mobile game built on the ARIS platform that was designed to engage 5th-9th grade players in NGSS science and engineering practices while they interacted with various exhibits. Same gender partners sharing one iPad would search for QR codes placed at specific exhibits; scanning a code within the game would launch a challenge for that exhibit. The primary hypothesis was that in- game victories would be equivalent to "mastery experiences" as described by Bandura (1997) and would result in increased science self-efficacy. Gender differences in gameplay behaviors and perceptions were also studied. The study included two groups, one that played the game during their visit and one that explored the science center in the traditional way. The Motivation to Learn Science Questionnaire was administered to participants in both groups both before and after their visit to the science center. Participants wore head-mounted GoPro cameras to record their interactions within the physical and social environment. No differences in affective outcomes were found between the game and comparison groups or between boys and girls in the game group. The MLSQ was unable to measure any significant change in science self-efficacy, interest and enjoyment of science, or overall motivation to learn science in either group. However, girls outperformed boys on every measure of game achievement. Lazzaro's (2004) four types of fun were found to be a good fit for describing the gender differences in game perceptions and behaviors. Girls tended to enjoy hard fun and collaborative people fun while boys enjoyed easy fun and competitive people fun. While boys associated game achievement with enjoyment and victory, girls perceived their game achievement as difficult, rather than enjoyable or victorious.

    Naomi Moran, a student at the Arnewood School, New Milton, Hampshire was the first recipient of the `Achievement in Physics' prize awarded by the South Central Branch of The Institute of Physics. Naomi received an award certificate and cheque for £100 from Dr Ruth Fenn, Chairman of the Branch, at the annual Christmas lecture held at the University of Surrey in December. She is pictured with Dr Fenn and Steve Beith, physics teacher at the Arnewood School.  Photo Figure 1. Naomi Moran receiving her award (photograph courtesy of Peter Milford). The award is intended to celebrate personal achievement in physics at any level at age 16-17 and is not restricted to those who gain the highest academic results. Schools across the county were invited to nominate suitable candidates; Naomi's nomination by the school's deputy head of science impressed the judges because of her ability to grasp the most difficult parts of the subject quickly, in addition to the fact that she took her AS-level science in year 11 when she was only 16. She is currently studying A-level physics, chemistry and mathematics and hopes to continue her studies at university later this year.

    2016-05-01

    Full Text Available This study is one of the first to estimate the impact of “inclusive“ science, technology, engineering, and mathematics (STEM high schools using student-level data. We use multiple statistical strategies to estimate the effect on student achievement from 2 years of attendance at six such high schools in Ohio. The results indicate that two schools had positive effects on science achievement that appear to come at the expense of achievement in social studies. The other schools had negligible or, often, negative effects across both STEM and, particularly, non-STEM subjects. These results are consistent with studies indicating that inclusive STEM schools typically focus on problem-based, personalized learning rather than science and mathematics content. The analysis also reveals the importance of accounting for students’ prior test scores in science, in addition to math and reading, when estimating models that use only 1 year of prior test score data—something that existing studies fail to do.

    The underrepresentation of women in science, technology, engineering, and mathematics (STEM)-related fields remains a concern for educators and the scientific community. Gender differences in mathematics and science achievement play a role, in conjunction with attitudes and self-efficacy beliefs. We report results from the 2011 Trends in Mathematics and Science Study (TIMSS), a large international assessment of eighth grade students' achievement, attitudes, and beliefs among 45 participating nations (N = 261,738). Small- to medium-sized gender differences were found for most individual nations (from d = -.60 to +.31 in mathematics achievement, and d = -.60 to +.26 for science achievement), although the direction varied and there were no global gender differences overall. Such a pattern cross-culturally is incompatible with the notion of immutable gender differences. Additionally, there were different patterns between OECD and non-OECD nations, with girls scoring higher than boys in mathematics and science achievement across non-OECD nations. An association was found between gender differences in science achievement and national levels of gender equality, providing support for the gender segregation hypothesis. Furthermore, the performance of boys was more variable than that of girls in most nations, consistent with the greater male variability hypothesis. Boys reported more favorable attitudes towards mathematics and science, and girls reported lower self-efficacy beliefs. While the gender gap in STEM achievement may be closing, there are still large sections of the world where differences remain.

    Terry, Brian H.

    In this quasi-experimental study, the researcher investigated the effectiveness of three tactual strategies and one non-tactual strategy of content specific vocabulary acquisition. Flash cards, task cards, and learning wheels served as the tactual strategies, and vocabulary review sheets served as a non-tactual strategy. The sample (n=85) consisted of all middle school students in a small high performing middle school located in the northern suburbs of New York City. All of the vocabulary words and terms came from the New York State Intermediate Level Science Core Curriculum. Pre-tests and post-tests were used to collect the data. A repeated measures ANOVA was conducted on the gain scores from each of the treatments. Multiple paired sample t-tests were conducted to analyze the results. Repeated measures ANOVAs were used to determine if there was a variance between the academic achievement levels of the students, gender, and grade level for each of the treatments. All of the treatments significantly improved the science achievement of the students, but significance was found between them. Significance was found between the achievement groups with the above average students attaining a higher mean on the pre-test and post-test for each treatment, whereas the below average students had the lowest mean on both assessments. The sixth grade students showed significant improvement over the seventh grade students while using the flash cards (p=.004) and learning wheel (p=.007). During the learning wheel treatment, the males scored significantly better (p=.021) than the females on the pre-test and post-test. During the worksheet treatment, significance (p=.034) was found between gender and achievement group. The below average male students had the greatest gain from the pre-test to the post-test, but the post-test mean was still the lowest of the groups. Limitations, implications for future research and current practice are discussed. Key words are: flash cards, task cards

    Christensen, Emily Fast

    The purpose of this research was to test an intervention of choices in homework on the achievement and intrinsic motivation of seventh-grade science students at a middle school. The intervention was based on concepts from the cognitive evaluation theory of Edward L. Deci and Richard M. Ryan (1985). The subjects were sixteen heterogeneous classes of seventh-grade students, who were divided among four teachers. Two randomly chosen classes from each teacher received choices in their homework and the remaining two classes of each teacher received similar homework assignments without choices. Two hypotheses were developed for this study: (1) Seventh-grade science students given choices in their homework would show an increase in intrinsic motivation as measured on a motivation orientation measure, compared to students not given choices in their homework, and (2) Seventh-grade science students given choices in their homework would show an increase in achievement on an achievement measure, compared to students not given choices in their homework. Having choices in homework did not increase intrinsic motivation or achievement. However, students who did their homework did significantly better on the posttest, and students who were more intrinsically motivated did significantly better on the posttest. Just doing the homework was important for achievement, and intrinsic motivation was linked to achievement.

  3. Examining the relationship between school district size and science achievement in Texas including rural school administrator perceptions of challenges and solutions

    Science.gov (United States)

    Mann, Matthew James

    Rural and small schools have almost one-third of all public school enrollment in America, yet typically have the fewest financial and research based resources. Educational models have been developed with either the urban or suburban school in mind, and the rural school is often left with no other alternative except this paradigm. Rural based educational resources are rare and the ability to access these resources for rural school districts almost non-existent. Federal and state based education agencies provide some rural educational based programs, but have had virtually no success in answering rural school issues. With federal and state interest in science initiatives, the challenge that rural schools face weigh in. To align with that focus, this study examined Texas middle school student achievement in science and its relationship with school district enrollment size. This study involved a sequential transformative mixed methodology with the quantitative phase driving the second qualitative portion. The quantitative research was a non-experimental causal-comparative study conducted to determine whether there is a significant difference between student achievement on the 2010 Texas Assessment of Knowledge and Skills 8 th grade science results and school district enrollment size. The school districts were distributed into four categories by size including: a) small districts (32-550); b) medium districts (551-1500); c) large districts (1501-6000); and d) mega-sized districts (6001-202,773). A one-way analysis of variance (ANOVA) was conducted to compare the district averages from the 2010 TAKS 8th grade science assessment results and the four district enrollment groups. The second phase of the study was qualitative utilizing constructivism and critical theory to identify the issues facing rural and small school administrators concerning science based curriculum and development. These themes and issues were sought through a case study method and through use of semi

    Several concepts from Georg Rasch's last papers are discussed. The key one is comparison because Rasch considered the method of comparison fundamental to science. From the role of comparison stems scientific inference made operational by a properly developed frame of reference producing specific objectivity. The exact specifications Rasch outlined for making comparisons are explicated from quotes, and the role of causality derived from making comparisons is also examined. Understanding causality has implications for what can and cannot be produced via Rasch measurement. His simple examples were instructive, but the implications are far reaching upon first establishing the key role of comparison.

    Pinder, Patrice J.

    Ogbu and Simons (1998) defined voluntary immigrants as individuals who chose to migrate to the United States (U.S.). Involuntary immigrants are defined as individuals whose ancestors were brought to the U.S. by force (Obgu & Simons, 1998). There have been recent reports indicating that voluntary immigrants are outperforming involuntary immigrants (Fisher, 2005; Williams, Fleming, Jones, & Griffin, 2007). There seems to be a trend in voluntary immigrants exhibiting a higher academic achievement pattern than involuntary immigrants (Fisher, 2005; Rong & Preissle, 1998; Williams et al., 2007). However, the reason for the groups' differences in achievement has not been extensively explored. The primary objective of this research study was to explore the impact of family background on the academic achievement patterns of Afro-Caribbean and African American students in the United States. The study utilized two research designs; a causal-comparative and a correlational design. A questionnaire was distributed to a sample of eighty-seven high school students. Eighteen of the participants were Afro-Caribbean students, and sixty-seven were African American students. Chemistry test scores for the students were also provided. The results of the study indicated that Afro-Caribbean students outperformed African American students on the test of science achievement. The difference was statistically significant (t= 2.43, pstudents' family backgrounds. Moreover, the findings of this study suggest that the positive impact of arrival status on the first-generation of Afro-Caribbean immigrants may be influencing their children's academic success in science. The present study holds a few implications for parents and teachers of immigrant minority students. Additionally, the current researcher has offered several implications for future research on ethnicity, immigration pattern, parenting, and achievement.

  11. Relationships Among Teacher Preparedness and Instructional Approaches to Secondary Student Achievement in STEM: A Secondary Analysis of TIMSS Data

    Miller-Ricks, Karen A.

    Educational reform efforts in Science, Technology, Engineering, Math (STEM) place emphasis on teachers as conduits for student achievement. The purpose of this study was to use TIMSS 2011 data to examine relationships between Science-Technology-Society (STS) instructional practices (student-centered instruction established to promote learning through real-world applications) teacher preparedness, and student achievement and identify variations of achievement between and among eighth-grade science and math classes. The research was framed by both Harper's Anti-Deficit Achievement Theory and Bronfenbrenner's Ecological Systems Theory (BEST). 501 U.S. schools contributed to the TIMSS 2011 data from both the teacher questionnaires and student booklets. Chi-Square, Spearman Correlation, and 2-level hierarchical linear modeling (HLM) were used to analyze data about teachers' preparedness to teach science and math, frequency of using STS instructional practices, and student achievement. The chi-square null hypothesis for math teachers was rejected, providing the assumption that there was an association between the frequency of using STS instruction in math and teacher preparedness. However, the chi-square null hypothesis for science teachers failed to be rejected, providing the assumption that there was no significant association between the frequency of using STS instruction in science and science teacher preparedness. The Spearman Correlation revealed statistically positively significant differences between STS instruction and science achievement, as well as between teacher preparedness and science achievement. The HLM results suggested that 33% of the variance of mathematics achievement was at the individual level and 66% was at the group level. The results for science teachers suggested that 54% of the variance of science achievement was at the individual level and 46% of the variance was at the group level. The data findings support the conclusion that secondary STEM

    Philpot, Cindy J.

    2007-12-01

    Recent reform efforts in science education focus on scientific literacy for all citizens. In order to be scientifically literate, an individual must have informed understandings of nature of science (NOS), scientific inquiry, and science content matter. This study specifically focused on Science Olympiad students' understanding of NOS as one piece of scientific literacy. Research consistently shows that science students do not have informed understandings of NOS (Abd-El-Khalick, 2002; Bell, Blair, Crawford, and Lederman, 2002; Kilcrease and Lucy, 2002; Schwartz, Lederman, and Thompson, 2001). However, McGhee-Brown, Martin, Monsaas and Stombler (2003) found that Science Olympiad students had in-depth understandings of science concepts, principles, processes, and techniques. Science Olympiad teams compete nationally and are found in rural, urban, and suburban schools. In an effort to learn from students who are generally considered high achieving students and who enjoy science, as opposed to the typical science student, the purpose of this study was to investigate Science Olympiad students' understandings of NOS and the experiences that formed their understandings. An interpretive, qualitative, case study method was used to address the research questions. The participants were purposefully and conveniently selected from the Science Olympiad team at a suburban high school. Data collection consisted of the Views of Nature of Science -- High School Questionnaire (VNOS-HS) (Schwartz, Lederman, & Thompson, 2001), semi-structured individual interviews, and a focus group. The main findings of this study were similar to much of the previous research in that the participants had informed understandings of the tentative nature of science and the role of inferences in science, but they did not have informed understandings of the role of human imagination and creativity, the empirical nature of science, or theories and laws. High level science classes and participation in

    Traditionally, women and minorities have not been fully represented in science and engineering. Numerous studies have attributed these differences to gaps in science achievement as measured by various standardized tests. Rather than describe mean group differences in science achievement across multiple cultures, this study focused on an in-depth item-level analysis across two countries: Spain and the United States. This study investigated eighth-grade gender differences on science items across the two countries. A secondary purpose of the study was to explore the nature of gender differences using the many-faceted Rasch Model as a way to estimate gender DIF. A secondary analysis of data from the Third International Mathematics and Science Study (TIMSS) was used to address three questions: 1) Does gender DIF in science achievement exist? 2) Is there a relationship between gender DIF and characteristics of the science items? 3) Do the relationships between item characteristics and gender DIF in science items replicate across countries. Participants included 7,087 eight grade students from the United States and 3,855 students from Spain who participated in TIMSS. The Facets program (Linacre and Wright, 1992) was used to estimate gender DIF. The results of the analysis indicate that the content of the item seemed to be related to gender DIF. The analysis also suggests that there is a relationship between gender DIF and item format. No pattern of gender DIF related to cognitive demand was found. The general pattern of gender DIF was similar across the two countries used in the analysis. The strength of item-level analysis as opposed to group mean difference analysis is that gender differences can be detected at the item level, even when no mean differences can be detected at the group level.

  17. Teaching 5th grade science for aesthetic understanding

    Science.gov (United States)

    Girod, Mark A.

    Many scientists speak with great zeal about the role of aesthetics and beauty in their science and inquiry. Few systematic efforts have been made to teach science in ways that appeal directly to aesthetics and this research is designed to do just that. Drawing from the aesthetic theory of Dewey, I describe an analytic lens called learning for aesthetic understanding that finds power in the degree to which our perceptions of the world are transformed, our interests and enthusiasm piqued, and our actions changed as we seek further experiences in the world. This learning theory is contrasted against two other current and popular theories of science learning, that of learning for conceptual understanding via conceptual change theory and learning for a language-oriented or discourse-based understanding. After a lengthy articulation of the pedagogical strategies used to teach for aesthetic understanding the research is described in which comparisons are drawn between students in two 5th grade classrooms---one taught for the goal of conceptual understanding and the other taught for the goal of aesthetic understanding. Results of this comparison show that more students in the treatment classroom had aesthetic experiences with science ideas and came to an aesthetic understanding when studying weather, erosion, and structure of matter than students in the control group. Also statistically significant effects are shown on measures of interest, affect, and efficacy for students in the treatment class. On measures of conceptual understanding it appears that treatment class students learned more and forgot less over time than control class students. The effect of the treatment does not generally depend on gender, ethnicity, or prior achievement except in students' identity beliefs about themselves as science learners. In this case, a significant interaction for treatment class females on science identity beliefs did occur. A discussion of these results as well as elaboration and

    Haun-Frank, Julie

    The purpose of this study was to examine the potential of a High School Health Science Career Academy to support African American students' science career trajectories. I used three key theoretical tools---critical science agency (Basu, 2007; Calabrese Barton & Tan, 2008), power (Nespor, 1994), and cultural production (Carlone, 2004; Eisenhart & Finkel, 1998) to highlight the intersections between the career trajectory implied by the Academy (its curriculum, classroom activities, and clinical experiences) and the students' pursued career trajectories. Data was collected over five months and included individual student interviews, group interviews, parent and administrator interviews, field notes from a culminating medical course and clinical internship, and Academy recruitment documents. The results of this study suggest that participants pursued a health science career for altruistic purposes and the Academy was a resource they drew upon to do so. However, the meanings of science and science person implied by the Academy hindered the possibility for many participants' to advance their science career trajectories. While the Academy promised to expose students to a variety of high-status health care roles, they were funneled into feminine, entry-level positions. This study adds to previous underrepresentation literature by contextualizing how identity-related factors influence African American students' career attainment.

    Drawing from Latino/a Critical Race Theory and the related Community Cultural Wealth (CCW) model, I concentrate on three forms of CCW---aspirational, navigational, and resistance capital---for this qualitative study on the undergraduate experience of Latina students in Science, Technology, Engineering, and Mathematics (STEM) majors, focusing on strategies and achieving baccalaureate attainment. I interviewed ten Latina students and asked them questions regarding their educational experiences in STEM majors, what contributed to their degree completion, and the strategies they employed for achieving baccalaureate attainment. I identified and described six themes within the study (the underrepresentation of Latinas in STEM majors, the lack of preparation by academic programs for upper division courses, motivators, involvement, time management, and support networks) that, when combined, contributed to participants' degree attainment. This study concludes with implications for policy and practice that would allow universities to better assist Latinas in STEM majors to achieve baccalaureate attainment.

  20. Exploring differential item functioning (DIF) with the Rasch model: A comparison of gender differences on eighth-grade science items in the United States and Spain

    Calvert, Tasha

    Despite the attention that has been given to gender and science, boys continue to outperform girls in science achievement, particularly by the end of secondary school. Because it is unclear whether gender differences have narrowed over time (Leder, 1992; Willingham & Cole, 1997), it is important to continue a line of inquiry into the nature of gender differences, specifically at the international level. The purpose of this study was to investigate gender differences in science achievement across two countries: United States and Spain. A secondary purpose was to demonstrate an alternative method for exploring gender differences based on the many-faceted Rasch model (1980). A secondary analysis of the data from the Third International Mathematics and Science Study (TIMSS) was used to examine the relationship between gender DIF (differential item functioning) and item characteristics (item type, content, and performance expectation) across both countries. Nationally representative samples of eighth grade students in the United States and Spain who participated in TIMSS were analyzed to answer the research questions in this study. In both countries, girls showed an advantage over boys on life science items and most extended response items, whereas boys, by and large, had an advantage on earth science, physics, and chemistry items. However, even within areas that favored boys, such as physics, there were items that were differentially easier for girls. In general, patterns in gender differences were similar across both countries although there were a few differences between the countries on individual items. It was concluded that simply looking at mean differences does not provide an adequate understanding of the nature of gender differences in science achievement.

    NASA is currently developing the capability to deploy deep space optical communications links. This creates the opportunity to utilize the optical link to obtain range, doppler, and signal intensity estimates. These may, in turn, be used to complement or extend the capabilities of current radio science. In this paper we illustrate the achievable precision in estimating range, doppler, and received signal intensity of an non-coherent optical link (the current state-of-the-art for a deep-space link). We provide a joint estimation algorithm with performance close to the bound. We draw comparisons to estimates based on a coherent radio frequency signal, illustrating that large gains in either precision or observation time are possible with an optical link.

    2010-12-01

    Columbia University's Summer Research Program for Science Teachers (SRP), founded in 1990, is one of the largest, best known university-based professional development programs for science teachers in the U.S. The program’s basic premise is simple: teachers cannot effectively teach science if they have not experienced it firsthand. For eight weeks in each of two consecutive summers, teachers participate as a member of a research team, led by a member of Columbia University’s research faculty. In addition to the laboratory experience, all teachers meet as a group one day each week during the summer for a series of pedagogical activities. A unique quality of the Summer Research Program is its focus on objective assessment of its impact on attitudes and instructional practices of participating teachers, on the performance of these teachers in their mentors’ laboratories, and most importantly, on the impact of their participation in the program on student interest and performance in science. SRP uses pass rate on the New York State Regents standardized science examinations as an objective measure of student achievement. SRP's data is the first scientific evidence of a connection between a research experience for teachers program and gains in student achievement. As a result of the research, findings were published in Science Magazine. The author will present an overview of Columbia's teacher research program and the results of the published program evaluation.

  3. An examination of single-gender and coeducational classes: Their impact on the academic achievement of middle school students enrolled in mathematics and science at selected schools in Georgia

    Elam, Jeanette H.

    The purpose of this study was to compare the academic performance of students enrolled in coeducational instruction and single-gender instruction. Within this framework, the researcher examined class type, gender, and racial/ethnicity using the sixth grade CRCT scores of selected students in the areas of mathematics and science. The fifth-grade mathematics and science scores for the same population were used to control for prior knowledge. This study examined the academic achievement of students based on class type, gender, and racial/ethnicity in relation to academic achievement. The study included the CRCT scores for mathematics and science of 6th-grade students at the middle school level who were tested during the 2007--2008 school year. Many studies conducted in the past have stressed females performed better in mathematics and science, while others have stated males performed better in the same areas. Yet, other studies have found conflicting results. A large Australian study (1996), compared the academic performance of students at single-gender and coeducational schools. The conclusion of this study indicated that both males and females who were educated in single-gender classrooms scored significantly higher than did males and females in coeducational classes. A study conducted by Graham Able (2003) documented superior academic performance of students in single-gender schools, after controlling for socioeconomic class and other variables. Able's most significant finding was that the advantage of single-gender schooling was greater for males in terms of academic results than for females. This directly contradicted the educational myth that males performed better in classrooms if females were present. The sample in this study consisted of CRCT scores for 304 sixth-grade students from four different middle schools. Due to the racial composition of the sample, the study only focused on black and white students. School 1 and School 2 involved single

    Performance tests are used for multiple purposes in exercise and sport science. Ensuring that a test displays an appropriate level of measurement properties for use within a population is important to ensure confidence in test findings. The aim of this study was to obtain subject matter expert consensus on the measurement and feasibility properties that should be considered for performance tests used in the exercise and sport sciences and how these should be defined. This information was used to develop a checklist for broader dissemination. A two-round Delphi study was undertaken including 33 exercise scientists, academics and sport scientists. Participants were asked to rate the importance of a range of measurement properties relevant to performance tests in exercise and sport science. Responses were obtained in binary and Likert-scale formats, with consensus defined as achieving 67% agreement on each question. Consensus was reached on definitions and terminology for all items. Ten level 1 items (those that achieved consensus on all four questions) and nine level 2 items (those achieving consensus on ≥2 questions) were included. Both levels were included in the final checklist. The checklist developed from this study can be used to inform decision-making and test selection for practitioners and researchers in the exercise and sport sciences. This can facilitate knowledge sharing and performance comparisons across sub-disciplines, thereby improving existing field practice and research methodological quality.

    Full Text Available The association between ICT diffusion and education is a subject of hot debate in both ICT and educational circles. Stances range from positive enthusiast, to skeptics, to disbelievers vis-a-vis the impact of ICT on students’ achievements. The purpose of this paper is to investigate the presence of any correlation between students’ academic achievements as recorded by Trends in International Mathematics and Science (TIMMS 2011 and the penetration of ICT in their schools and households, with focus primarily on computers and the Internet. The paper relies on the analysis of the data published by the Trends in International Mathematics and Science Study (TIMMS 2011, international study center and the international association for the evaluation of educational achievements. Statistical data analysis will be employed to figure out whether there is any correlation between the penetration level of ICT and the students’ score in math and science tests as recorded by the TIMMS 2011 international scale. The analysis conducted within the scope of this research indicates the lack of any association between ICT use and students achievements in math and science subjects. Though the linkage between students’ achievements is not a straightforward issue that can be uncovered via simple regression analysis, however, the results definitely indicate that employment of ICT in both schools and homes is an insignificant factor that can be easily offset by other major factors, like socio-economic conditions, instruction resources, teachers’ capabilities, or cultural factors.

    The number of American students entering science and engineering careers and their ranking in comparison with other countries is on the decline. This decline has alarmed Congress which, in 1987, established a Task Force on Women, Minorities, and the Handicapped in Science and Technology to define the problem and find solutions. If left unchanged, the task force has warned that the prospects for maintaining an advanced industrial society will diminish. NASA is supportive of the six goals outlined by the task force, which are paraphrase herein, and is carefully assessing its education programs to identify those offering the greatest potential for achieving the task force objectives with a reasonable range of resources. A major initiative is under way on behalf of NASA at its Marshall Space Flight Center, where highly effective features of several NASA education programs along with innovations are being integrated into a comprehensive pilot program. This program, dubbed Project LASER, is discussed.

    2003-05-01

    For many college students in the sciences, organic chemistry poses a difficult challenge. Indeed, success in organic chemistry has proven pivotal in the careers of a vast number of students in a variety of science disciplines. A better understanding of the factors that contribute to achievement in this course should contribute to efforts to increase the number of students in the science disciplines. Further, an awareness of gender differences in factors associated with achievement should aid efforts to bolster the participation of women in chemistry and related disciplines. Using a correlation research design, the individual relationships between organic chemistry achievement and each of several cognitive variables and noncognitive variables were assessed. In addition, the relationships between organic chemistry achievement and combinations of these independent variables were explored. Finally, gender- and instructor-related differences in the relationships between organic chemistry achievement and the independent variables were investigated. Cognitive variables included the second-semester general chemistry grade, the ACT English, math, reading, and science-reasoning scores, and scores from a spatial visualization test. Noncognitive variables included anxiety, confidence, effectance motivation, and usefulness. The second-semester general chemistry grade was found to be the best indicator of performance in organic chemistry, while the effectiveness of other predictors varied between instructors. In addition, gender differences were found in the explanations of organic chemistry achievement variance provided by this study. In general, males exhibited stronger correlations between predictor variables and organic chemistry achievement than females.

  13. Response to science education reforms: The case of three science education doctoral programs in the United States

    Gwekwerere, Yovita Netsai

    Doctoral programs play a significant role in preparing future leaders. Science Education doctoral programs play an even more significant role preparing leaders in a field that is critical to maintaining national viability in the face of global competition. The current science education reforms have the goal of achieving science literacy for all students and for this national goal to be achieved; we need strong leadership in the field of science education. This qualitative study investigated how doctoral programs are preparing their graduates for leadership in supporting teachers to achieve the national goal of science literacy for all. A case study design was used to investigate how science education faculty interpreted the national reform goal of science literacy for all and how they reformed their doctoral courses and research programs to address this goal. Faculty, graduate students and recent graduates of three science education doctoral programs participated in the study. Data collection took place through surveys, interviews and analysis of course documents. Two faculty members, three doctoral candidates and three recent graduates were interviewed from each of the programs. Data analysis involved an interpretive approach. The National Research Council Framework for Investigating Influence of the National Standards on student learning (2002) was used to analyze interview data. Findings show that the current reforms occupy a significant part of the doctoral coursework and research in these three science education doctoral programs. The extent to which the reforms are incorporated in the courses and the way they are addressed depends on how the faculty members interpret the reforms and what they consider to be important in achieving the goal of science literacy for all. Whereas some faculty members take a simplistic critical view of the reform goals as a call to achieve excellence in science teaching; others take a more complex critical view where they question

    Britner, Shari L.; Pajares, Frank

    The purpose of this study was to discover whether the science motivation beliefs of middle school students (N = 262) vary as a function of their gender or race/ethnicity and to determine whether science self-efficacy beliefs predict science achievement when motivation variables shown to predict achievement in other academic areas are controlled. Girls reported stronger science self-efficacy and self-efficacy for self-regulation, and they received higher grades in science. Boys had stronger performance-approach goals. White students had stronger self-efficacy and achievement, and African American students reported stronger task goals. Self-efficacy was the only motivation variable to predict the science achievement of girls, boys, and White students. Self-efficacy and self-concept predicted the science achievement of African American students. Results are interpreted from the perspective of Bandura's social cognitive theory.

    Painter, Jason

    The purpose of this study was to examine a proposed motivational model of science achievement based on self-determination theory. The study relied on U.S. eighth-grade science data from the 2007 Third International Mathematics and Science Study to examine a structural model that hypothesized how perceived autonomy support, perceived competence in science, intrinsic motivation, and science achievement related to each other. Mother's education and student gender were used as controls. Findings showed that the hypothesized model provided a good fit to the data. The strongest direct effect on science achievement was students' perceived competence in science. Student intrinsic motivation was shown to have a surprisingly negative effect on science achievement. Autonomy support had positive direct effects on students' perceived competence in science and intrinsic motivation and had indirect positive effects to science achievement. Results and implications for science education are discussed.

    1976-01-01

    For measurement of nuclear power station achievement against original purchase the usual gross output figures are of little value since the term loosely covers many different definitions. An authentically designed output figure has been established which relates to net design output plus house load at full load. Based on these figures both cumulative and moving annual load factors are measured, the latter measuring the achievement over the last year, thus showing trends with time. Calculations have been carried out for all nuclear stations in the Western World with 150 MW(e) gross design output and above. From these are shown: moving annual load factor indicating relative station achievements for all the plants; cumulative load factors from which return of investment can be calculated; average moving annual load factors for the four types of system Magnox, PWR, HWR, and BWR; and a relative comparison of achievement by country in a few cases.

The main goal of this study was to present academic achievement causal model based on the dimensions of goal orientation and learning approaches among the students of Medical Science and Dentistry courses in Guilan University of Medical Sciences in 2013. Methods: This study is based on a cross-sectional model. The participants included 175 first and second year students of the Medical and Dentistry schools in Guilan University of Medical Sciences selected by random cluster sampling [121 persons (69% Medical Basic Science students and 54 (30.9% Dentistry students]. The measurement tool included the Goal Orientation Scale of Bouffard and Study Process Questionnaire of Biggs and the students’ Grade Point Average. The study data were analyzed using Pearson correlation coefficient and structural equations modeling. SPSS 14 and Amos were used to analyze the data. Results: The results indicated a significant relationship between goal orientation and learning strategies (P<0.05. In addition, the results revealed that a significant relationship exists between learning strategies [Deep Learning (r=0.37, P<0.05, Surface Learning (r=-0.21, P<0.05], and academic achievement. The suggested model of research is fitted to the data of the research. Conclusion: Results showed that the students’ academic achievement model fits with experimental data, so it can be used in learning principles which lead to students’ achievement in learning.

    The compilation features of Jingluo Shuxue Xue ( Science of Meridians and Acupoints ) among different editions were summarized and analyzed. Jingluo Xue ( Science of Meridians ) and Shuxue Xue ( Science of Acupoints ) published by Shanghai Scientific and Technical Publishers in 1984 are the pioneer as the textbook for the education of acupuncture discipline for the bachelor degree, but there is the big controversy for the editions in 1996. These two books were combined as one, titled Science of Meridians and Acupoints , 2013 edition, published by China Press of Traditional Chinese Medicine. It is concise and coherent in content and is regarded as the milestone in the history of textbook compilation. This book was re-edited in 2007 without major changes in content. The one in 2009 was revised a lot on the basis of the original several editions, published by Shanghai Scientific and Technical Publishers. But unfortunately, it did not bring the big impacts in China. The edition in 2012, published by China Press of Traditional Chinese Medicine had made the innovations besides integrating the achievements of the previous editions, characterized as preciseness and conciseness. By contrast, the edition in 2012, published by People's Medical Publishing House was accomplished by simple modification on the basis of the editions in 2003 and in 2007, without great innovation. Regarding the on-going publication of the textbooks in "the 13th five-year plan", it is viewed that the new edition of textbook should maintain the general framework of "the 12th five-year plan", based on which, a few questions should be revised appropriately. Additionally, "less words, more illustration" should be the basic principle for the revision of the new edition.

    Crosley, Haver

    This research was designed to determine the relative effectiveness of a Multi-sensory Instructional Package (MIP) (Dunn & Dunn, 1992) versus Traditional Teaching (TT) on the science achievement- and attitude-test scores of middle-school English Language Learner (ELL) and English-speaking sixth-, seventh-, and eighth-grade middle-school students. The dependent variables were students' science- and attitude-test scores. The independent variables were the two instructional strategies, ELL and English-speaking (Non-ELL) status, and three grade levels. The sample consisted of 282 sixth-, seventh-, and eighth-grade ELL and Non-ELL middle-school students. Learning Styles: The Clue to You! (LS: CY) (Burke & Dunn, 1998) was administered to determine learning-style preferences. The control groups were taught sixth-, seventh-, and eighth-grade science lessons traditionally and the experimental groups were instructed on the same units using MIPs. The Semantic Differential Scale (SDS) (Pizzo, 1981) was administered to reveal attitudinal differences. All three groups experienced both traditional and multi-sensory instruction in all three sub-units. The data subjected to statistical analyses supported the use of an MIP rather than a traditional approach for teaching science content to both ELLs and English-speaking middle-school students. Analysis of variance (ANOVA) revealed a positive and significant impact on achievement scores. Furthermore, the students indicated significantly more positive attitudes when instructed with an MIP approach.

    2017-02-15

    This review aims at providing a practical overview of the use of statistical features and associated data science methods in bioimage informatics. To achieve a quantitative link between images and biological concepts, one typically replaces an object coming from an image (a segmented cell or intracellular object, a pattern of expression or localisation, even a whole image) by a vector of numbers. They range from carefully crafted biologically relevant measurements to features learnt through deep neural networks. This replacement allows for the use of practical algorithms for visualisation, comparison and inference, such as the ones from machine learning or multivariate statistics. While originating mainly, for biology, in high content screening, those methods are integral to the use of data science for the quantitative analysis of microscopy images to gain biological insight, and they are sure to gather more interest as the need to make sense of the increasing amount of acquired imaging data grows more pressing.

  14. Grouped to Achieve: Are There Benefits to Assigning Students to Heterogeneous Cooperative Learning Groups Based on Pre-Test Scores?

    Science.gov (United States)

    Werth, Arman Karl

    Cooperative learning has been one of the most widely used instructional practices around the world since the early 1980's. Small learning groups have been in existence since the beginning of the human race. These groups have grown in their variance and complexity overtime. Classrooms are getting more diverse every year and instructors need a way to take advantage of this diversity to improve learning. The purpose of this study was to see if heterogeneous cooperative learning groups based on student achievement can be used as a differentiated instructional strategy to increase students' ability to demonstrate knowledge of science concepts and ability to do engineering design. This study includes two different groups made up of two different middle school science classrooms of 25-30 students. These students were given an engineering design problem to solve within cooperative learning groups. One class was put into heterogeneous cooperative learning groups based on student's pre-test scores. The other class was grouped based on random assignment. The study measured the difference between each class's pre-post gains, student's responses to a group interaction form and interview questions addressing their perceptions of the makeup of their groups. The findings of the study were that there was no significant difference between learning gains for the treatment and comparison groups. There was a significant difference between the treatment and comparison groups in student perceptions of their group's ability to stay on task and manage their time efficiently. Both the comparison and treatment groups had a positive perception of the composition of their cooperative learning groups.

  16. Challenging traditional assumptions of high school science through the physics and Everyday Thinking Curriculum(TM)

    Science.gov (United States)

    Ross, Michael J.

    Science education in the U.S. has failed for over a century to bring the experience of scientific induction to classrooms, from elementary science to undergraduate courses. The achievement of American students on international comparisons of science proficiency is unacceptable, and the disparities between groups underrepresented in STEM and others are large and resistant to reform efforts. This study investigated the enactment of a physics curriculum designed upon the inductive method in a high school serving mostly students from groups underrepresented in science. The Physics and Everyday Thinking curriculum was designed to model the central practices of science and to provide opportunities for students to both extract general principles of physics and to develop scientific models from laboratory evidence. The findings of this study suggest that scientific induction is not only a process that is well within the capacity of high school students, but they enjoy it as well. Students that engaged in the central practices of science through the inductive method reported a new sense of agency and control in their learning. These findings suggest that modeling the pedagogy of the science classroom upon the epistemology of science can result in a mode of learning that can lead to positive identification with physics and the development of scientific literacy.

    2005-07-01

    The purpose of this research study was to examine, for undergraduate women of various Asian American ethnic backgrounds, the influence of background contextual and college environment factors on their sense of academic self-efficacy and achievement in science, technology, engineering, and mathematics (STEM) majors. Social cognitive career theory and its critiques provided a theoretical foundation for relationships from past performance, socioeconomic status, acculturation, and college environment variables (compositional diversity, racial climate, gendered climate, academic peer support), to academic self-efficacy and achievement. Data were collected through an online survey. Instrumentation included the scales of Language, Identity, and Behavioral Acculturation; Gender Discrimination; Faculty and Classroom Behavior; Interactions with Peers; and Academic Milestones Self-efficacy. The participants were 228 Asian American undergraduate women in STEM at a large public, doctoral research extensive university on the east coast; the response rate was 51%. In three MANOVAs for nine social cognitive career variables, four ethnic groups (East, South, Southeast, and Multi-ethnic Asian American) significantly differed only on socioeconomic status. In path analysis, the initial model was not a good fit and was rejected. The model was respecified through statistical and theoretical evaluation, tested in exploratory analysis, and considered a good fit. The respecified model explained 36% of semester GPA (achievement) and 28% of academic self-efficacy. The academic achievement of Asian American women in STEM was related to past performance, background contextual factors, academic self-efficacy, academic peer support, and gendered climate. The strongest direct influence on achievement was academic self-efficacy followed by past performance. The total effect of Asian acculturation on achievement was negative and the total effect of American acculturation on achievement was not

    Howell, Donna

    This mixed-methods action research study was designed to assess the achievement of ninth-grade Physical Science Honors students by analysis of pre and posttest data. In addition, perceptual data from students, parents, and the researcher were collected to form a complete picture of the flipped lecture format versus the traditional lecture format. The researcher utilized a 4MAT learning cycle in two Physical Science Honors classes. One of these classes was traditionally delivered with lecture-type activities taking place inside the classroom and homework-type activities taking place at home; the other inverted, or flipped, delivered with lecture-type activities taking place outside the classroom and homework-type activities taking place inside the classroom. Existing unit pre and posttests for both classes were analyzed for differences in academic achievement. At the completion of the units, the flipped class students and parents were surveyed, and student focus groups were convened to ascertain their perceptions of the flipped classroom delivery model. Statistical analysis of posttest data revealed that there is no significant difference between the traditional lecture delivery format and the flipped delivery format. Analysis of perceptual data revealed six themes that must be considered when deciding to flip the classroom: how to hold students accountable for viewing the at-home videos, accessibility of students to the required technology, technical considerations relating to the video production, comprehension of the material both during and after viewing the videos, pedagogy of the overall flipped method, and preference for the flipped method overall. Findings revealed that students, parents, and the researcher all had a preference for the flipped class format, provided the above issues are addressed. The flipped class format encourages students to become more responsible for their learning, and, in addition, students reported that the hands-on inquiry

  20. Science anxiety and social cognitive factors predicting STEM career aspirations of high school freshmen in general science class

    Skells, Kristin Marie

    Extant data was used to consider the association between science anxiety, social cognitive factors and STEM career aspirations of high school freshmen in general science classes. An adapted model based on social cognitive career theory (SCCT) was used to consider these relationships, with science anxiety functioning as a barrier in the model. The study assessed the following research questions: (1) Do social cognitive variables relate in the expected way to STEM career aspirations based on SCCT for ninth graders taking general science classes? (2) Is there an association between science anxiety and outcomes and processes identified in the SCCT model for ninth graders taking general science classes? (3) Does gender moderate these relationships? Results indicated that support was found for many of the central tenants of the SCCT model. Science anxiety was associated with prior achievement, self-efficacy, and science interest, although it did not relate directly to STEM career goals. Gender was found to moderate only the relationship between prior achievement and science self-efficacy.

    In medical education, the effect of the educational environment on student achievement has primarily been investigated in comparisons between traditional and problem-based learning (PBL) curricula. As many of these studies have reached no clear conclusions on the superiority of the PBL approach, the effect of curricular reform on student performance remains an issue. We employed a theoretical framework that integrates antecedents of student achievement from various psychosocial domains to examine how students interact with their curricular environment. In a longitudinal study with N = 1,646 participants, we assessed students in a traditional and a PBL-centered curriculum. The measures administered included students' perception of the learning environment, self-efficacy beliefs, positive study-related affect, social support, indicators of self-regulated learning, and academic achievement assessed through progress tests. We compared the relations between these characteristics in the two curricular environments. The results are two-fold. First, substantial relations of various psychosocial domains and their associations with achievement were identified. Second, our analyses indicated that there are no substantial differences between traditional and PBL-based curricula concerning the relational structure of psychosocial variables and achievement. Drawing definite conclusions on the role of curricular-level interventions in the development of student's academic achievement is constrained by the quasi-experimental design as wells as the selection of variables included. However, in the specific context described here, our results may still support the view of student activity as the key ingredient in the acquisition of achievement and performance.

    Although communist ideology claimed to destroy former class stratification based on labor market capitalist relationships, de facto during socialism one social class hierarchy was substituted for another that was equally unequal. The economic transition during the 1990s increased stratification by wealth, which affected educational inequality. This study examines the relationships among parental education, gender, educational expectations, and mathematics achievement of youths in five post-socialist Eastern European countries, comparing them with three Western countries. We employed the 8 th -grade data from the Trends in International Mathematics and Science Study (TIMSS) 1995 and 2007. The findings point to the universal associations between parental education and student outcomes, whereas gender comparisons present interesting East-West differences. The theoretical and policy implications of these findings are discussed.

    The recent NRC panel on "Achieving Science with Cubesats" found that "CubeSats have already proven themselves to be an important scientific tool. CubeSats can produce high-value science, as demonstrated by peer-reviewed publications that address decadal survey science goals." While some science is purely related to the size of the collecting aperture, there are plentiful examples of new and exciting experiments that can be achieved using the relatively inexpensive Cubesat platforms. We will present various potential science applications that can benefit from higher bandwidth communication. For example, on or near Earth orbit, Cubesats could provide hyperspectral imaging, gravity field mapping, atmospheric probing, and terrain mapping. These can be achieved either as large constellations of Cubesats or a few Cubesats that provide multi-point observations. Away from the Earth (up to 1AU) astrophysical variability studies, detections of solar particles between the Earth and Venus, mapping near earth objects, and high-speed videos of the Sun will also be enabled by high bandwidth communications.

    2011-04-01

    The use of cooperative learning in secondary school is reported - an area of considerable concern given attempts to make secondary schools more interactive and gain higher recruitment to university science courses. In this study the intervention group was 259 pupils aged 12-14 years in nine secondary schools, taught by 12 self-selected teachers. Comparison pupils came from both intervention and comparison schools (n = 385). Intervention teachers attended three continuing professional development days, in which they received information, engaged with resource packs and involved themselves in cooperative learning. Measures included both general and specific tests of science, attitudes to science, sociometry, self-esteem, attitudes to cooperative learning and transferable skills (all for pupils) and observation of implementation fidelity. There were increases during cooperative learning in pupil formulation of propositions, explanations and disagreements. Intervened pupils gained in attainment, but comparison pupils gained even more. Pupils who had experienced cooperative learning in primary school had higher pre-test scores in secondary education irrespective of being in the intervention or comparison group. On sociometry, comparison pupils showed greater affiliation to science work groups for work, but intervention pupils greater affiliation to these groups at break and out of school. Other measures were not significant. The results are discussed in relation to practice and policy implications.

  6. van Eijck and Roth's utilitarian science education: why the recalibration of science and traditional ecological knowledge invokes multiple perspectives to protect science education from being exclusive

    Science.gov (United States)

    Mueller, Michael P.; Tippins, Deborah J.

    2010-12-01

    This article is a philosophical analysis of van Eijck and Roth's (2007) claim that science and traditional ecological knowledge (TEK) should be recalibrated because they are incommensurate, particular to the local contexts in which they are practical. In this view, science maintains an incommensurate status as if it is a "fundamental" basis for the relative comparison of other cultural knowledges, which reduces traditional knowledge to a status of in relation to the prioritized (higher)-status of natural sciences. van Eijck and Roth reject epistemological Truth as a way of thinking about sciences in science education. Rather they adopt a utilitarian perspective of cultural-historical activity theory to demonstrate when traditional knowledge is considered science and when it is not considered science, for the purposes of evaluating what should be included in U.S. science education curricula. There are several challenges for evaluating what should be included in science education when traditional knowledges and sciences are considered in light of a utilitarian analysis. Science as diverse, either practically local or theoretically abstract, is highly uncertain, which provides opportunities for multiple perspectives to enlarge and protect the natural sciences from exclusivity. In this response to van Eijck and Roth, we make the case for considering dialectical relationships between science and TEK in order to ensure cultural diversity in science education, as a paradigm. We also emphasize the need to (re)dissolve the hierarchies and dualisms that may emerge when science is elevated in status in comparison with other knowledges. We conclude with a modification to van Eijck and Roth's perspective by recommending a guiding principle of cultural diversity in science education as a way to make curriculum choices. We envision this principle can be applied when evaluating science curricula worldwide.

  7. An examination of the relationship among Iiraqi high school students' science achievement and perceptions of the value of education, parent support, and peer support in the United States

    Al-Mandwee, Samir F.

    The objective of this dissertation was to quantitatively study Iraqi students (N=90) who arrived in the U.S.A. in the last 20 years. A non-experimental, descriptive research design was used for this study, which took place in one of three high schools in a large Midwestern suburban school district, during the 2013--2014 academic year. Three factors, including the students' perception of the value of education, the parental support, and the peer support, were examined using the Facilitating Conditions Questionnaire. The three subscales were part of a larger self-administered questionnaire used by McInerney (1997). In addition to the FCQ survey, a student demographic questionnaire was also used in the survey. Quantitative data from the FCQ survey reported that the students' perception of the value of education and their perception of peer support had a significant relationship with science academic achievement, which was measured for two semesters. Moreover, their peer support was the only predictor for science achievement.

  10. Expecting success: Factors influencing ninth graders' science self-efficacy

    Science.gov (United States)

    Donahue, Elizabeth

    What factors influence ninth grade students' expectations for success in science? Using social cognitive theory and bioecological systems theory as theoretical frameworks, this dissertation employs data from the High School Longitudinal Study of 2009 (HSLS:09) to examine the relative impact of teacher practices and their perceived attitudes on students' science self-efficacy. Further, as they relate to this broader issue, the relative impact of student subjective task value and teacher characteristics is also investigated. It has been well documented that U.S. students are not achieving at satisfactory levels in science. Education policy has focused on improving science teacher quality as one way to address this problem. Teacher effectiveness has been primarily measured by student achievement on standardized tests. However, not enough attention has been given to the social cognitive factors that can lead to increased achievement and persistence in science as well as how teachers may influence these factors. This study interrogates the relationship between student and teacher variables and the social cognitive construct of self-efficacy, which has proven to have a significant impact on student achievement and persistence in science. Findings add to the current literature surrounding ways that educators may increase student performance in science by employing policies and practices that benefit the development of student science self-efficacy.

  11. The correlation between academic achievements, self-esteem and motivation of female seventh grade students: A mixed methods approach

    Science.gov (United States)

    Henman, Karen

    During the early grades, female students generally display enthusiasm for learning science. As these same students go though school, however, their level of motivation changes. Once female students reach high school, many lack the confidence to take chemistry and physics. Then, in college they lack the background necessary to major in chemistry, physics, and engineering. This study used quantitative data to investigate the correlation between female students' motivation, self-esteem, and standards-based state science achievement tests combined with a qualitative survey of student's perceptions of parents' attitudes toward science. The Children's Science Motivation Inventory (CAIMI) determined students' levels of motivation toward science. The Coopersmith Self-esteem Inventory (CSEI) ascertained female students' overall self-esteem. The ISTEP+ exam given in the 6th grade measured the students' academic achievement in science. Trained examiners who interviewed students comprised the qualitative component of the study. Each examiner elaborated on selected questions from the CSEI and CAIMI to determine the students' perceptions of parental attitudes toward science. A multiple regression was used to determine the correlation between self-esteem, motivation, and achievement in science. The correlation was strongest between motivation. Interviews revealed parents and teachers had the most influence on students' perception of science. In understanding the correlation between female students' motivation, achievement, and self-esteem, schools will gain further knowledge into how students relate to the academic field of science and can thus promote females' participation in more science courses in high school. This then will provide females the necessary background knowledge to pursue a greater number of science majors in college.

    In this research, we investigate impression management (IM) as a substantive personality variable by linking it to differentiated achievement motivation constructs, namely achievement motives (workmastery, competitiveness, fear of failure) and achievement goals (mastery-approach, mastery-avoidance, performance-approach, performance-avoidance). Study 1 revealed that IM was a positive predictor of workmastery and a negative predictor of competitiveness (with and without self-deceptive enhancement (SDE) controlled). Studies 2a and 2b revealed that IM was a positive predictor of mastery-approach goals and mastery-avoidance goals (without and, in Study 2b, with SDE controlled). These findings highlight the value of conceptualising and utilising IM as a personality variable in its own right and shed light on the nature of the achievement motive and achievement goal constructs. © 2016 International Union of Psychological Science.

    Curiosity is fundamental to scientific inquiry and pursuance. Parents are important in encouraging children's involvement in science. This longitudinal study examined pathways from parental stimulation of children's curiosity per se to their science acquisition (SA). A latent variable of SA was indicated by the inter-related variables of high school science course accomplishments, career interest, and skill. A conceptual model investigated parental stimulation of children's curiosity as related to SA via science intrinsic motivation and science achievement. The Fullerton Longitudinal Study provided data spanning school entry through high school (N = 118). Parental stimulation of curiosity at age 8 years comprised exposing children to new experiences, promoting curiosity, encouraging asking questions, and taking children to a museum. Intrinsic motivation was measured at ages 9, 10, and 13 years, and achievement at ages 9, 10, and 11 years. Structural equation modelling was used for analyses. Controlling for socio-economic status, parental stimulation of curiosity bore positive and significant relations to science intrinsic motivation and achievement, which in turn related to SA. Gender neither related to stimulation of curiosity nor contributed to the model. Findings highlight the importance of parental stimulation of children's curiosity in facilitating trajectories into science, and relevance to science education is discussed.

    This paper reports the findings of a study of the impact of the transformative professional development (TPD) model on student achievement on state-mandated assessments of science in elementary school. Two schools (one intervention and one control) participated in the case study where teachers from one school received the TPD intervention across a 2-year period while teachers at the other school received no program and continued business as usual. The TPD program includes a focus on the core conceptual framework for effective professional development (Desimone in Educ Res 38:181-199, 2009) as well as an emphasis on culturally relevant pedagogy (CRP) and other effective science instructional strategies. Findings revealed that participation in TPD had a significant impact on student achievement for Burns Elementary with the percentage of proficient students growing from 25 % at baseline to 67 % at the end of the 2-year program, while the comparison school did not experience similar growth. Implications for future research and implementation of professional development programs to meet the needs of teachers in the realm of CRP in science are discussed.

    2011-07-01

    The apartheid policies in South Africa had a marked influence on the accessibility and quality of school science experienced by the different race groups. African learners in particular were seriously disadvantaged in this regard. The issues of equity and redress were foremost in transformation of the education system, and the accompanying curriculum reform. This paper reports on equity in terms of equality of outputs and equality of inputs in South African school science, with a particular focus on the implementation of practical science investigations. This was a qualitative case study of two teachers on their implementation of science investigations at two schools, one a township school, previously designated for black children, and the other a former Model C school, previously reserved for white children. My study was guided by the curriculum implementation framework by Rogan and Grayson in trying to understand the practice of these teachers at schools located in contextually diverse communities. The framework helped profile the implementation of science investigations and also enabled me to explore the factors which are able to support or hinder this implementation.

    2013-04-01

    The Brazilian Soil Science Society (SBCS) is one of the oldest scientific societies in Brazil. It was created in October 1947 during the 1st Brazilian Meeting of Soil Science held at the headquarters of the Agricultural Chemistry Institute of Rio de Janeiro, at present the Soils Institute of the Brazilian Agricultural Research Centre. Its origin lies within the Interamerican Conference of Agriculture, Caracas, 1945, the 2nd Pan American Congress of Mining and Geology, Petropolis, Rio de Janeiro, 1946 and the 5th Brazilian Congress of Chemistry, Porto Alegre, 1947. Its first president was Álvaro Barcelos Fagundes, who was the only Brazilian participant at the 1st International Congress of Soil Science and Transcontinental Excursion held in United States of America, in 1927. At that time he was engaged in research work at the New Jersey Agricultural Experiment Station, at the Rutgers University where he did a doctorate under the guidance of Professor Selman Waksman. The society started with 47 members and presently has nearly 900 members. In its first phase the Brazilian Soil Science Society was housed at the Agricultural Chemistry Institute in Rio de Janeiro and its main activity was the biannual Brazilian Congress of Soil Science. In 1975 its headquarters moved to the Agronomic Institute of Campinas with the creation of its executive board and the start of publication of the Brazilian Journal of Soil Science (1977) as well as the society bulletin (1976). In 1997 its executive office moved to the Soils Department at the Federal University of Viçosa. Nowadays it has a structure similar to the one from the IUSS: the society is organized in four divisions (Soil in space and time, Soils properties and processes, Soil use and management and Soil, environment and society) which encompass 14 technical commissions and eight State or Regional nuclei. The Brazilian Congresses of Soil Science happen without interruption since 1947. The first one had had 72 participants that

    Full Text Available The aim of the study was to investigate the effect of perceived motivational structure of classroom on achievement behaviors (the choice of problem, effort, persistence in solving algorithm and flowchart problems. There were 45 high school male students (Mean age = 17 years old in the third grade of computer field in three classes. Classes were divided into two experimental and one control group. Instructional content was given in 10 sessions for 180 minutes. The variables of choice, effort, and persistence were collected by direct as-sessment method. A pre-test and post-test design was used. The Data were analyzed by using multivariate analysis of variance. Results indicated that mastery structure had positive effect on the amount of effort and persistence in solving algorithm and flowchart problems in comparison with control group. Mastery structure in comparison with performance structure increased the amount of effort in solving problems significantly. In addition, an interactive effect between previous achieve-ment and perceived structure of classroom was achieved in a mastery level. The amount of persistence in that of students with very weak previous achievement was more than students with average previous achievement. The find-ing of this study is compatible with the theory of achievement goal and illustrates that the mastery structure plays an effective role in forming achievement behaviors.

    Identification and analysis of the components of labor productivity based on ACHIEVE model was performed among employees in different parts of Kermanshah University of Medical Sciences in 2014. This was a descriptive correlational study in which the population consisted of 270 working personnel in different administrative groups (contractual, fixed- term and regular) at Kermanshah University of Medical Sciences (872 people) that were selected among 872 people through stratified random sampling method based on Krejcie and Morgan sampling table. The survey tool included labor productivity questionnaire of ACHIEVE. Questionnaires were confirmed in terms of content and face validity, and their reliability was calculated using Cronbach's alpha coefficient. The data were analyzed by SPSS-18 software using descriptive and inferential statistics. The mean scores for labor productivity dimensions of the employees, including environment (environmental fit), evaluation (training and performance feedback), validity (valid and legal exercise of personnel), incentive (motivation or desire), help (organizational support), clarity (role perception or understanding), ability (knowledge and skills) variables and total labor productivity were 4.10±0.630, 3.99±0.568, 3.97±0.607, 3.76±0.701, 3.63±0.746, 3.59±0.777, 3.49±0.882 and 26.54±4.347, respectively. Also, the results indicated that the seven factors of environment, performance assessment, validity, motivation, organizational support, clarity, and ability were effective in increasing labor productivity. The analysis of the current status of university staff in the employees' viewpoint suggested that the two factors of environment and evaluation, which had the greatest impact on labor productivity in the viewpoint of the staff, were in a favorable condition and needed to be further taken into consideration by authorities.

    This study extends the scope of international comparisons examining students' conceptions of the equal sign. Specifically, Korean (n = 193) and Turkish (n = 334) Grade 6 students were examined to assess whether their conceptions and responses were similar to prior findings published for Chinese and U.S. students and to hypothesize relationships about problem types and conceptual understanding of the equal sign. About 59.6% of the Korean participants correctly answered all items providing conceptually accurate solutions, as compared to 28.4% of the Turkish sample. Comparison with previous studies in China and the USA indicated that the Chinese sample outperformed those from other nations, followed by Korea, Turkey, and the USA. In large-scale international studies such as Trends in International Mathematics and Science (TIMSS) and the Programme for International Student Assessment (PISA), students from China and Korea have been among the high achievers.

    Liskey, Brian K.

    This research project was designed to examine the factors that affect students' choice in a career. Specifically, the factors of (a) achievement, (b) interest, (c) self-efficacy, (d) perceived preparation for a career, and (e) being informed about a career will be under investigation. Of key importance to the study is how these factors can affect a student's perception about choosing a science career. A quantitative analysis of secondary data from the 2006 and 2009 Program for International Student Assessment (PISA) international assessment and attitudinal questionnaire provided data on student perceptions and aptitude in science. The sample from PISA included over 400,000 15 year-old students from 57 countries. From the 57 countries, 30 countries, comprised by Organization for Economic and Cooperative Development (OECD), were isolated for analysis. Within this group of 30, 11 were selected for comparison based on their questionnaire response to expectations for a career in science at age 30. The Institute for Educational Science's, International Data Explorer was utilized to acquire and analyze data from the 2006 and 2009 PISA international tests and questionnaires to determine significance between scaled scores and PISA indices. Variables were chosen as factors affecting student's perception on various systems outlined by the Systems Theory of Career Development (Patton & McMahon, 1997) and the Systems Theory of Career Development Framework (Patton & McMahon, 1999). Four country groups were established based on student responses to question 30a from the 2006 PISA attitudinal questionnaire, which asks what career students expected to have at age 30. The results from comparing country groups showed that countries in Group A, which showed the highest values for students expecting a career in science, also had the highest average values for achievement on the PISA science literacy assessment. Likewise, countries that had the lowest values for expecting a career in

    Full Text Available In the light of the poor academic achievement in science by secondary school students in South Africa, students' motivation for science learning should be enhanced. It is argued that this can only be achieved with insight into which motivational factors to target, with due consideration of the diversity in schools. The study therefore explored the impact of six motivational factors for science learning in a sample of 380 Grade Nine boys and girls from three racial groups, in both public and independent schools. The students completed the Student Motivation for Science Learning questionnaire. Significant differences were identified between different groups and school types. The study is important for identifying the key role of achievement goals, science learning values and science self-efficacies. The main finding emphasises the significant role played by science teachers in motivating students for science in terms of the learning environments that they create. This has important implications for future research, aimed at a better understanding of these environments. Such insights are needed to promote scientific literacy among the school students, and so contribute to the improvement of science achievement in South Africa.

    Recent mathematics assessment findings indicate that Native American students tend to score below students of the ethnic majority. Findings suggest that students' beliefs about mathematics are significantly related to achievement outcomes. This study examined relations between self-beliefs and mathematics achievement for a national sample of 130 Grade 8 Native American students from the Trends in International Mathematics and Science Study (TIMSS) 2003 United States sample of (M age = 14.2 yr., SD = 0.5). Multiple regression indicated several significant relations of mathematics beliefs with achievement and accounted for 26.7% of the variance in test scores. Students who earned high test scores tended to hold more positive beliefs about their ability to learn mathematics quickly, while students who earned low scores expressed negative beliefs about their ability to learn new mathematics topics.

  17. Science Education at Riverside Middle School A Case Study

    Science.gov (United States)

    Smiley, Bettie Ann Pickens

    For more than thirty years the gender gap in science and related careers has been a key concern of researchers, teachers, professional organizations, and policy makers. Despite indicators of progress for women and girls on some measures of achievement, course enrollment patterns, and employment, fewer women than men pursue college degrees and careers in science, technology, engineering, and mathematics. According to the results of national assessments, the gender gap in science achievement begins to be evident in the middle school years. Gender and school science achievement involve a complex set of factors associated with schools and child/family systems that may include school leadership, institutional practices, curriculum content, teacher training programs, teacher expectations, student interests, parental involvement, and cultural values. This ethnographic case study was designed to explore the context for science education reform and the participation of middle school girls. The study analyzed and compared teaching strategies and female student engagement in sixth, seventh, and eighth grade science classrooms. The setting was a middle school situated in a district that was well-known for its achievement in reading, math, and technology. Findings from the study indicated that while classroom instruction was predominantly organized around traditional school science, the girls were more disciplined and outperformed the boys. The size of the classrooms, time to prepare for hands-on activities, and obtaining resources were identified as barriers to teaching science in ways that aligned with recent national science reform initiatives. Parents who participated in the study were very supportive of their daughters' academic progress and career goals. A few of the parents suggested that the school's science program include more hands-on activities; instruction designed for the advanced learner; and information related to future careers. Overall the teachers and

    Dowey, Ana Lucrecia

    The under participation of minority females in STEM fields has been a chronic problem in the United States, mainly when it is analyzed through the lens of their relative representation in the population. The results of the first or quantitative phase, of this two phase sequential, mixed method study, revealed academic achievement or performance in science accounted for most of the variance of mean scores for students' attitudes and interests in science as measured by the TOSRA Likert-scale survey, when compared to the degree of parent education and ethnicity/ racial background. Additionally, this study investigated possible sources of perceived self-efficacy in eighteen seventh grade Hispanic female students by conducting personal semi-structured interviews. The purpose of this study was to explore if middle school female student ethnic/racial backgrounds and academic performance influence their attitudes and interests toward science and to study the possible effects external (family, school, peers, and community) and internal factors may have for Hispanic student self-efficacy toward science. The results revealed that of the five ethnic/racial groups studied, Asian/Filipino female students expressed higher positive attitudes and interests toward science, than the rest of the student ethnic groups studied, followed by the Hispanic student group. The results indicated that students' perceived encouragement from their mothers, regardless of the mother's degree of education, as being the main source of these girls' perceived self-efficacy in science. However, the lack of perceived school-related, peer-related, and community-related support was evident. These results are encouraging because they demonstrate how verbal persuasion, in the form of encouragement and support, fosters perceived self-efficacy for minority female students.

    An important part of the ARGONA project is the testing and application of novel participation and dialogue approaches. The Czech Republic is one of the countries where these approaches will be applied and tested. The ways in this is being done include a series of events involving different stakeholders such as a focused science shop, a consensus panel and an interaction panel. In the framework of these activities in the Czech Republic the focused science shop was held on March 12, 2008 in the Nuclear Research Institute (NRI) in Rez, and addressed the theme: 'Radioactive waste management and radiation risk in comparison with other hazardous waste and risks'. The main goal of this focused science shop was to increase awareness amongst the public of actual and potential effects of radioactive and toxic wastes and to prioritise questions/uncertainties that people might have in this field. The following topics were discussed: - Differences in the general perception of nuclear waste in comparison with other toxic wastes; - General public awareness of the issue of nuclear waste management and other toxic wastes management; - Management and ultimate disposal of radioactive waste and other toxic waste in terms of the technology employed; - NIMBY effect. A broader audience was selected with a suitable mixture of specialists and interested technical and non-technical peers including representatives from NRI, universities, Ministry of Industry and Trade, Ministry of the Environment, State Office for Nuclear Safety and Radioactive Waste Repository Authority, representatives of municipalities and NGOs, and waste producers such as CEZ plc etc. In the Czech Republic there is a general unwillingness by the public to actively participate in the NWM decision-making process. Therefore, despite all the efforts made by the project team, not all invited stakeholders attended the meeting. Despite this, the meeting was very positively received by those who did attend and indicates the

    Full Text Available Renzulli Learning is an on-line educational profile and educational learning system designed to match student interests, learning styles, and expression styles with a vast array of educational activities and resources designed to enrich and engage students’ learning process. In this experimental study, quantitative procedures were used to investigate the use of Renzulli Learning on oral reading fluency, reading comprehension, science achievement, social studies achievement of 383 elementary and middle schools students. The research took place in two schools, an urban middle school in Georgia where half of all students are considered to be at risk due to poverty or other factors, and a suburban elementary school in southern California. Students in grades 3 5 (n = 185 and grades 6 8 (n = 198 were randomly assigned to use Renzulli Learning for 2-3 hours each week for a 16-week period. Students in the treatment groups were compared to students who did not have the opportunity to use Renzulli Learning in control classes in the same schools. A two-way repeated-measures ANOVA was used to explore differences between treatment and control students. After 16 weeks, students who participated in Renzulli Learning demonstrated significantly higher growth in reading comprehension (p < .001, significantly higher growth in oral reading fluency (p = .016, and significantly higher growth in social studies achievement (p = .013 than those students who did not participate in Renzulli Learning.

    2015-12-01

    A 2014 survey conducted by the Pew Research Center asked members of the American Association for the Advancement of Science about their support for active engagement in public policy debates. The survey found that 87% of the respondents supported scientists taking an active role in public policy debates about science and technology (S&T), but most believed that regulations related to areas like land use and clean air and water are not guided by the best science. Despite the demand for actionable scientific information by policy makers, these survey results underscore the gap that exists between the scientific and the public policy communities. There are fundamental differences that exist between the perspectives of these two groups, even within Federal S&T agencies that are required to balance the perspectives of the science and policy communities in order to fulfill their agency mission. In support of an ongoing agency effort to strengthen communication and interaction among staff, we led a Federal S&T agency office through an examination and comparison of goals, processes, external drivers, decision making, and timelines within their organization. This workshop activity provided an opportunity to identify the interdependence of science and policy, as well as the challenges to developing effective science-based policy solutions. The workshop featured strategies for achieving balanced science policy outcomes using examples from a range of Federal S&T agencies. The examples presented during the workshop illustrated best practices for more effective communication and interaction to resolve complex science policy issues. The workshop culminated with a group activity designed to give participants the opportunity to identify the challenges and apply best practices to real world science policy problems. Workshop examples and outcomes will be presented along with lessons learned from this agency engagement activity.

    Reading the interesting article Discerning selective traditions in science education by Per Sund , which is published in this issue of CSSE, allows us to open the discussion on procedures for teaching science today. Clearly there is overlap between the teaching of science and other areas of knowledge. However, we must constantly develop new methods to teach and differentiate between science education and teaching science in response to the changing needs of our students, and we must analyze what role teachers and teacher educators play in both. We must continually examine the methods and concepts involved in developing pedagogical content knowledge in science teachers. Otherwise, the possibility that these routines, based on subjective traditions, prevent emerging processes of educational innovation. Modern science is an enormous field of knowledge in its own right, which is made more expansive when examined within the context of its place in society. We propose the need to design educative interactions around situations that involve science and society. Science education must provide students with all four dimensions of the cognitive process: factual knowledge, conceptual knowledge, procedural knowledge, and metacognitive knowledge. We can observe in classrooms at all levels of education that students understand the concepts better when they have the opportunity to apply the scientific knowledge in a personally relevant way. When students find value in practical exercises and they are provided opportunities to reinterpret their experiences, greater learning gains are achieved. In this sense, a key aspect of educational innovation is the change in teaching methodology. We need new tools to respond to new problems. A shift in teacher education is needed to realize the rewards of situating science questions in a societal context and opening classroom doors to active methodologies in science education to promote meaningful learning through meaningful teaching.

  8. Case study: Comparison of motivation for achieving higher performance between self-directed and manager-directed aerospace engineering teams

    Erlick, Katherine

    "The stereotype of engineers is that they are not people oriented; the stereotype implies that engineers would not work well in teams---that their task emphasis is a solo venture and does not encourage social aspects of collaboration" (Miner & Beyerlein, 1999, p. 16). The problem is determining the best method of providing a motivating environment where design engineers may contribute within a team in order to achieve higher performance in the organization. Theoretically, self-directed work teams perform at higher levels. But, allowing a design engineer to contribute to the team while still maintaining his or her anonymity is the key to success. Therefore, a motivating environment must be established to encourage greater self-actualization in design engineers. The purpose of this study is to determine the favorable motivational environment for design engineers and describe the comparison between two aerospace design-engineering teams: one self-directed and the other manager directed. Following the comparison, this study identified whether self-direction or manager-direction provides the favorable motivational environment for operating as a team in pursuit of achieving higher performance. The methodology used in this research was the case study focusing on the team's levels of job satisfaction and potential for higher performance. The collection of data came from three sources, (a) surveys, (b) researcher observer journal and (c) collection of artifacts. The surveys provided information regarding personal behavior characteristics, potentiality for higher performance and motivational attributes. The researcher journal provided information regarding team dynamics, individual interaction, conflict and conflict resolution. The milestone for performance was based on the collection of artifacts from the two teams. The findings from this study illustrated that whether the team was manager-directed or self-directed does not appear to influence the needs and wants of the

  9. Children's learning of science through literature

    O'Kelly, James B.

    This study examined the effects of picture books belonging to different literary genres on the learning of science by primary grade students. These genres included modern fantasy, fiction, and nonfiction. The students were exposed to two topics through books, butterflies and snails. The study focused on the effects of those books on children's expressions of (a) knowledge, (b) erroneous information, (c) creative ideas, and (d) the support required to elicit information and ideas from the children. Sixty-one children from three kindergarten and three second grade participated. Children were designated by their teachers as being high or low with respect to academic achievement. These categories allowed measurement of interactions between literary genres, grade levels, and academic achievement levels. Children first learned about butterflies, and then about snails. For each topic, children were interviewed about their knowledge and questions of the topic. Teachers engaged their classes with a book about the topic. The children were re-interviewed about their knowledge and questions about the topic. No class encountered the same genre of book twice. Comparisons of the children's prior knowledge of butterflies and snails indicated that the children possessed significantly more knowledge about butterflies than about snails. Literary genre had one significant effect on children's learning about snails. Contrary to expectations, children who encountered nonfiction produced significantly more creative expressions about snails than children who encountered faction or modern fantasy. No significant effects for literary genre were demonstrated with respect to children's learning about butterflies. The outcomes of the study indicated that nonfiction had its strongest impact on the learning of science when children have a relatively small fund of knowledge about a topic. This study has implications for future research. The inclusion of a larger number of students, classes, and

    Full Text Available Orientation: Measurement invariance is one of the most precarious aspects of the scale development process without which the interpretation of research findings on population subgroups may be ambiguous and even invalid. Besides tests for validity and reliability, measurement invariance represents the hallmark for psychometric compliance of a new measuring instrument and provides the basis for inference of research findings across a range of relevant population sub-groups. Research purpose: This study tested the measurement invariance of a Learning Programme Management and Evaluation (LPME scale across levels of academic achievement. Motivation for the study: It is important for any researcher involved in new scale development to ensure that the measurement instrument and its underlying constructs have proper structural alignment and that they both have the same level of meaning and significance across comparable heterogeneous groups. Research design, approach and method: A quantitative, non-experimental, cross-sectional survey design was used, and data were obtained from 369 participants who were selected from three public sector organisations using a probabilistic simple random sampling technique. The Statistical Package for Social Sciences and Analysis of Moment Structures software (versions 21.0.0 were used to analyse the data. Main findings: The findings show that all the four invariance models tested have achieved acceptable goodness-of-fit indices. Furthermore, the findings show that the factorial structure of the LPME scale and the meaning of its underlying constructs are invariant across different levels of academic achievement for human resource development (HRD practitioners and learners or apprentices involved in occupational learning programmes. Practical implications: The findings of this study suggest practical implications for HRD scholars as they are enabled to make informed decisional balance comparisons involving educational

    Full Text Available Science education plays a critical role as political priority due to its fundamental importance in engaging students to pursue technological careers considered essential in modern societies, in order to face scientific development challenges. High-level achievement on science education and positive attitudes toward science constitutes a crucial challenge for formal education. Several studies indicate close relationships between students’ attitudes, cognitive abilities, and academic achievement. The main purpose of this study is to analyze the impact of student’s attitudes toward the school discipline of Physics and Chemistry and their reasoning abilities on academic achievement on that school subject, among Portuguese 9th grade students using the data collected during the Project Academic Performance and Development: a longitudinal study on the effects of school transitions in Portuguese students (PTDC/CPE-CED/104884/2008. The participants were 470 students (267 girls – 56.8% and 203 boys – 43.2%, aged 14–16 years old (μ = 14.3 ± 0.58. The attitude data were collected using the Attitude toward Physics-Chemistry Questionnaire (ATPCQ and, the Reasoning Test Battery (RTB was used to assess the students reasoning abilities. Achievement was measured using the students’ quarterly (9-week grades in the physics and chemistry subject. The relationships between the attitude dimensions toward Physics-chemistry and the reasoning dimensions and achievement in each of the three school terms were assessed by multiple regression stepwise analyses and standardized regression coefficients (β, calculated with IBM SPSS Statistics 21 software. Both variables studied proved to be significant predictor variables of school achievement. The models obtained from the use of both variables were always stronger accounting for higher proportions of student’s grade variations. The results show that ATPCQ and RTB had a significantly positive relationship with

    The study explored the changes in pre-service science teachers' understanding of the nature of science and their opinions about the nature of science, science teaching and argumentation after their participation in explicit nature of science (NOS) and socioscientific argumentation processes. The participants were 56 third-grade pre-service science teachers studying in a state university in Turkey. The treatment group comprised 27 participants, and there were 29 participants in the comparison group. The comparison group participants were involved in a student-centred science-teaching process, and the participants of the treatment group were involved in explicit NOS and socioscientific argumentation processes. In the study, which lasted a total of 11 weeks, a NOS-as-argumentation questionnaire was administered to all the participants to determine their understanding of NOS at the beginning and end of the data collection process, and six random participants of the treatment group participated in semi-structured interview questions in order to further understand their views regarding NOS, science teaching and argumentation. Qualitative and quantitative data analysis revealed that the explicit NOS and socioscientific argumentation processes had a significant effect on pre-service science teachers' NOS understandings. Furthermore, NOS, argumentation and science teaching views of the participants in the treatment group showed a positive change. The results of this study are discussed in light of the related literature, and suggestions are made within the context of contribution to science-teaching literature, improvement of education quality and education of pre-service teachers.

    During the last 3 decades, Iran has experienced a rapid population growth and at the same time the health of Iranian people has improved greatly. This achievement was mainly due to training and availability of health manpower, well organized public health network and medical science and research improvement. In this article, we aimed to report the relevant data about the medical science and research situation in Iran and compare them with other countries. In this study, after reviewing science development and research indicators in medical sciences with participation of key stakeholders, we selected 3 main hybrid indexes consisting of "Research and Development (R&D) expenditures," "Personnel in Science and Technology sector" and "knowledge generation" for evaluation of medical science and research situation. Data was extracted from reliable databases. Over the past decade, Iran has achieved significant success in medical sciences and for the first time in 2015 based on Scopus index, Iran ranked first in the number of published scientific papers and number of citations in the region and among all Islamic countries. Also, 2% of the world's publications belong to Iran. Regarding innovation, the number of Iranian patents submitted to the United States Patent and Trademark Office (USPTO) was 3 and 43 in 2008 and 2013, respectively. In these years, the number of personnel in science and technology sectors including post graduate students, researchers and academic members in universities of medical sciences (UMSs) have increased. The female students in medical sciences field account for about twothirds of all students. Also, women comprise about one-third of faculty members. Since 5 years ago, Iran has had growth in science and technology parks. These achievements were attained in spite of the fact that research spending in Iran was still very low (0.5% of gross domestic product [GDP]) due to economic hardships and sanctions. Medical science and research development has

    As the electric power industry moves from the regulated monopoly environment to one of open competition, the need to achieve and maintain a competitive advantage becomes critical. In the competitive market, having a competitive edge means having goods and services that the market prefers, i.e., buyers in the market prefer to purchase your goods and services rather than your competitors'. For electric power generating facilities, the market is the wholesale market, and because electric power is essentially a commodity, i.e., a megawatthour from one generating facility is the same as a megawatthour from another generating facility, the primary distinguishing factor in the market is price.d therefore, having a competitive edge in the market means having a lower price than the competition. This paper describes the basic elements of achieving a competitive edge and discusses how these elements are being used by two utilities with very different circumstances to improve their competitive positions

    The Soil Education and public awareness technical commission of the Brazilian Soil Science Society was created in 1987 as Soil Science teaching commission at that time. In the 90's of the last century the commission was very active and realized three national symposia in the years 1994 to 1996: in Viçosa, Minas Gerais; Santa Maria, Rio Grande do Sul and Pato Branco, Paraná. The following symposium scheduled to happen in Brasilia, 1997 could not be realized and was followed by a weakening and reduction of the involved group. Those three symposia were focused on the aspects of soil science taught at the university educational level, mainly in agrarian sciences. The concern about what was going on at basic education and perception by society was not much present. The commission was revitalized in 2005 and in 2007 realized its first meeting at the Brazilian Congress of Soil Science in Gramado, Rio Grande do Sul. At that meeting it was already an urge to assume the approach of soil education instead of soil science teaching, within a major concern how society consider soils. It was accepted and adequate under the structural reorganization undergone by the national society following the IUSS main lines. The commission was renamed and got two new mates at the newly created Division IV, Soils, Environment and Society, of the Brazilian Soil Science Society: Soils and Food Safety and History, Epistemology and Sociology of Soil Science. The national symposia were relaunched to happen biannually. An inventory of the soil education experiences around the country started and the geographic distribution of the future symposia intended to rescue and bring together experiences in different parts of the country that would not be known by other means. Three symposia were already realized: Piracicaba, Sao Paulo, 2008 (southeast); Curitiba, Paraná, 2010 (south) and Sobral, Ceará, 2012 (northeast). The next is planned to happen in Recife, Pernambuco in April 2014. The scope of the

    Mandell, Brian E.

    The purpose of the present embedded mixed method study was to examine the self-regulatory processes used by high, average, and low achieving seventh grade students as they learned about a complex science topic from a hypermedia learning environment. Thirty participants were sampled. Participants were administered a number of measures to assess their achievement and self-efficacy. In addition, a microanalytic methodology, grounded in Zimmerman's cyclical model of self-regulated learning, was used to assess student self-regulated learning. It was hypothesized that there would be modest positive correlations between Zimmerman's three phases of self-regulated learning, that high achieving science students would deploy more self-regulatory subprocesses than average and low achieving science students, that high achieving science students would have higher self-efficacy beliefs to engage in self-regulated learning than average and low achieving science students, and that low achieving science students would over-estimate their self-efficacy for performance beliefs, average achieving science students would slightly overestimate their self-efficacy for performance beliefs, and high achieving science students would under-estimate their self-efficacy for performance beliefs. All hypotheses were supported except for the high achieving science students who under-estimated their self-efficacy for performance beliefs on the Declarative Knowledge Measure and slightly overestimated their self-efficacy for performance beliefs on the Conceptual Knowledge Measure. Finally, all measures of self-regulated learning were combined and entered into a regression formula to predict the students' scores on the two science tests, and it was revealed that the combined measure predicted 91% of the variance on the Declarative Knowledge Measure and 92% of the variance on the Conceptual Knowledge Measure. This study adds hypermedia learning environments to the contexts that the microanalytic

    In the opening keynote address to the conference, Professor Helen Garnett, Executive Director of ANSTO, outlined the Organisation's main achievements and its future directions. In the ten years which have elapsed since its inception in 1987, ANSTO has evolved into a forward thinking, proactive nuclear science and technology Organisation. Its vision for the future is for nuclear science and technology to be accepted as benefiting all Australians and for ANSTO to be acknowledged as the premier nuclear science and technology organisation within the Asia Pacific Region. At the same time the organisation has continually reviewed and evaluated what it was doing and how it was doing. At the end of its first decade, it has enhanced the productivity from its research and development activities, received a positive evaluation on the impact that the application of this knowledge is having on the minerals and other industrial sectors, and focussed its research and development into a few areas where substantial teams of ANSTO staff, working cooperatively with staff from universities, other national organisations and industry, can have significant impact. ANSTO now has four parallel activities: the conduct of research and development, the provision of expert technical advice, the operation of national nuclear facilities and the commercial marketing of products and services. The recent announcement by Australian Government to replace HIFAR reactor with a leading medium flux reactor facility, will enable ANSTO to develop world class capability in selected areas of neutron science and to became an acknowledged regional centre, particular in cold neutron science

    2013-06-01

    Our study gathered data to serve as a benchmark of demographics of undergraduate students in game degree programs. Due to the high number of programs that are cross-disciplinary with computer science programs or that are housed in computer science departments, the data is presented in comparison to data from computing students (where available) and the US population. Participants included students studying games at four nationally recognized postsecondary institutions. The results of the study indicate that there is no significant difference between the ratio of men to women studying in computing programs or in game degree programs, with women being severely underrepresented in both. Women, blacks, Hispanics/Latinos, and heterosexuals are underrepresented compared to the US population. Those with moderate and conservative political views and with religious affiliations are underrepresented in the game student population. Participants agree that workforce diversity is important and that their programs are adequately diverse, but only one-half of the participants indicated that diversity has been discussed in any of their courses.

  9. Teacher Research Programs: An Effective Form of Professional Development to Increase Student Achievement and Benefit the Economy

    2008-12-01

    U.S. high school students perform markedly less well in science, technology, engineering and math (STEM) than students in other economically advanced countries. This low level of STEM performance endangers our democracy and economy. The President's Council of Advisors in Science and Technology's 2004 report attributed the shortfall of students attracted to the sciences is a result of the dearth of teachers sufficiently conversant with science and scientists to enable them to communicate to their students the excitement of scientific exploration and discovery, and the opportunities science provides for highly rewarding and remunerative careers. Nonetheless, the United States has made little progress in correcting these deficiencies. Studies have shown that high-quality teaching matters more to student achievement than anything else schools do. This belief is buttressed by evidence from Columbia University's Summer Research Program for Science Teachers (SRP) that highly motivated, in-service science teachers require professional development to enable them and their students to perform up to their potential. Columbia's Summer Research Program is based on the premise that to teach science effectively requires experience in using the tools of contemporary science to answer unsolved questions. From its inception, SRP's goal has been to enhance interest and improve performance in science of students. It seeks to achieve this goal by increasing the professional competence of teachers. The reports of Elmore, Sanders and Rivers, and our own studies, show that professional development is a "key lever for improving student outcomes." While most middle and high school science teachers have taken college science courses that include cookbook laboratory exercises, the vast majority of them have never attempted to answer an unsolved question. Just as student learning depends on the expertise of teachers, the expertise of teachers depends on the quality of their professional

    Full Text Available The objective of the present study was to investigate the relationship between time management, perceived stress, gender and academic achievement among United Arab Emirates college students. The respondents were 352 college students from Al Ain University of Science and Technology. The sample was stratified by sex. Among the respondents, 52.5% were female students and 47.5% were male students. The mean age of the sample was 23.4 years ranging from 18 to 39. Time management was measured by Time Management Questionnaire” developed by Britton and Tesser (1991, while perceived stress was measured by The Perceived Stress Scale developed by Cohen (1985. The findings of the study showed that there was statistically significant negative relationship between time management and perceived stress. Females reported higher time management compared to their males counter mates. Higher time management and lower perceived stress were associated with high levels of academic achievement. However, time management was the most significant predictor of academic achievement accounting for 26 % of the variance while perceived stress accounted for an additional 11.2% of the variance in academic achievement. All three predictors explained 29.4% (R = .543 of total variance. The implications and limitations are reviewed as are the suggestions for future research.   Keywords: Time management, perceived stress, academic achievement, college students.

    In response to frequent news media reports about how poorly American students fare compared with their peers abroad, Daniel Koretz takes a close look at what these comparisons say, and do not say, about the achievement of U.S. high school students. He stresses that the comparisons do not provide what many observers of education would like: unambiguous information about the effectiveness of American high schools compared with those in other nations. Koretz begins by describing the. two principal international student comparisons-the Trends in International Mathematics and Science Study (TIMSS) and the Program for International Student Assessment (PISA). Both assessments, he stresses, reflect the performance of students several years before they complete high school. PISA, which targets fifteen-year-old students, measures students' abilities to apply what they have learned in school to real-world problems. By contrast, TIMSS tests fourth and eighth graders. Unlike PISA, TIMSS follows the school curriculum closely. Because the findings of the two tests are sometimes inconsistent, Koretz stresses the importance of considering data from both sources. He cautions against comparing U.S. students with an "international average," which varies widely from survey to survey depending on which countries participate, and recommends instead comparing them with students in other nations that are similar to the United States or that are particularly high-achieving. Many observers, says Koretz, speculate that the lackluster average performance of American students in international comparisons arises because many, especially minority and low-income U.S. students, attend low-performing schools. But both TIMSS and PISA, he says, show that the performance of American students on the exams is not much more variable than that of students in countries that are socially more homogeneous or that have more equitable educational systems. Koretz emphasizes that the international comparisons

    The purposes of this study were to determine if a relationship exists between biology achievement and (1) number of topics, (2) topic duration, (3) curricular focus, and (4) science achievement using TIMSS data from Population 3---the final year of secondary school. Students included in this study were subsets of the 55,675 students from 22 countries who participated in the science literacy portion of TIMSS at the Population 3 level (IEA, 1997). The sample included in this study for the four research questions were comprised of between (1) 17,769 and 37,794 students from 15 countries, (2) 17,769 and 37,794 students from 15 countries, (3) 21,715 and 46,458 students from 18 countries, and (4) 19,518 and 46,458 students from 18 countries, respectively. A Pearson's product moment correlation was used to determine whether a relationship exists between the number of biology topics addressed by intended national science curricula and mean student achievement on selected items by country. No statistically significant correlation was found by country between biology achievement and number of topics. To determine whether a relationship exists between the topic duration of biology topics addressed by released, biology-oriented, Population 3 Science Literacy items and student achievement on those items, a Pearson's product moment correlation was also used. A statistically significant correlation between biology achievement and topic duration for only one topic (Interdependence of Life) was found at the .05 level of significance. A possible relationship between the degree of curricular focus of Population 3 TIMSS countries and student achievement on selected items by country was evaluated using a Pearson's product moment correlation. No statistically significant correlation by country between biology achievement and degree of curricular focus was found. A Pearson's product moment correlation was used to determine whether a relationship exists between science literacy

  16. Distinguishing between forensic science and forensic pseudoscience: testing of validity and reliability, and approaches to forensic voice comparison.

    In this paper it is argued that one should not attempt to directly assess whether a forensic analysis technique is scientifically acceptable. Rather one should first specify what one considers to be appropriate principles governing acceptable practice, then consider any particular approach in light of those principles. This paper focuses on one principle: the validity and reliability of an approach should be empirically tested under conditions reflecting those of the case under investigation using test data drawn from the relevant population. Versions of this principle have been key elements in several reports on forensic science, including forensic voice comparison, published over the last four-and-a-half decades. The aural-spectrographic approach to forensic voice comparison (also known as "voiceprint" or "voicegram" examination) and the currently widely practiced auditory-acoustic-phonetic approach are considered in light of this principle (these two approaches do not appear to be mutually exclusive). Approaches based on data, quantitative measurements, and statistical models are also considered in light of this principle. © 2013.

    Computer science and the liberal arts have much to offer each other. Yet liberal arts colleges, in particular, have been slow to recognize the opportunity that the study of computer science provides for achieving the goals of a liberal education. After the precipitous drop in computer science enrollments during the first decade of this century,…

    Science is a way of knowing about the world. At once a process, a product, and an institution, science enables people to both engage in the construction of new knowledge as well as use information to achieve desired ends. Access to science--whether using knowledge or creating it--necessitates some level of familiarity with the enterprise and…

  19. Coverage and quality: A comparison of Web of Science and Scopus databases for reporting faculty nursing publication metrics.

    Web of Science and Scopus are the leading databases of scholarly impact. Recent studies outside the field of nursing report differences in journal coverage and quality. A comparative analysis of nursing publications reported impact. Journal coverage by each database for the field of nursing was compared. Additionally, publications by 2014 nursing faculty were collected in both databases and compared for overall coverage and reported quality, as modeled by Scimajo Journal Rank, peer review status, and MEDLINE inclusion. Individual author impact, modeled by the h-index, was calculated by each database for comparison. Scopus offered significantly higher journal coverage. For 2014 faculty publications, 100% of journals were found in Scopus, Web of Science offered 82%. No significant difference was found in the quality of reported journals. Author h-index was found to be higher in Scopus. When reporting faculty publications and scholarly impact, academic nursing programs may be better represented by Scopus, without compromising journal quality. Programs with strong interdisciplinary work should examine all areas of strength to ensure appropriate coverage. Copyright © 2017 Elsevier Inc. All rights reserved.

  20. Enhancing interdisciplinary, mathematics, and physical science in an undergraduate life science program through physical chemistry.

    BIO2010 advocates enhancing the interdisciplinary, mathematics, and physical science components of the undergraduate biology curriculum. The Department of Chemistry and Life Science at West Point responded by developing a required physical chemistry course tailored to the interests of life science majors. To overcome student resistance to physical chemistry, students were enabled as long-term stakeholders who would shape the syllabus by selecting life science topics of interest to them. The initial 2 yr of assessment indicates that students have a positive view of the course, feel they have succeeded in achieving course outcome goals, and that the course is relevant to their professional future. Instructor assessment of student outcome goal achievement via performance on exams and labs is comparable to that of students in traditional physical chemistry courses. Perhaps more noteworthy, both student and instructor assessment indicate positive trends from year 1 to year 2, presumably due to the student stakeholder effect.
