    As science instructors we are faced with two main barriers with respect to student learning. The first is motivating our students to attend class and the second is to make them active participants in the learning process once we have gotten them to class. As we head further into the internet age this problem only gets exacerbated as students have replaced newspapers with cell phones which can surf the web, check their emails, and play games. Quizzes can motivated the students to attend class but do not necessarily motivate them to pay attention. Active learning techniques work but we as instructors have been bombarded by the active learning message to the point that we either do it already or refuse to. I present another option which in my classroom has doubled the rate at which students learn my material. By using attendance worksheets instead of end of class quizzes I hold students accountable for not just their attendance but for when they show up and when they leave the class. In addition it makes the students an active participant in the class even without using active learning techniques as they are writing notes and answering the questions you have posed while the class is in progress. Therefore using attendance worksheets is an effective tool to use in order to guide student learning.

    The Soil Science Society of America created its K12 Committee in 2006 in part to compliment the Dig It! The Secrets of Soil exhibit that opened in July 2008 at the Smithsonian's Institution's Nation Museum of Natural History (of which SSS was a founding sponsor). The committee's work began quickly with a website designed to provide resources for K12 teachers. The first accomplishments included reviewing and posting links to web based information already available to teachers. These links were sorted by subject and grade level to make it easier for teachers to navigate the web and find what they needed quickly. Several presentations and lessons designed for K12 teachers were also posted at this time. Concurrent with this effort a subcommittee review and organized the national teaching standards to show where soils could fit into the overall K12 curriculum. As the website was being developed another subcommittee developed a soils book (Soil! Get the Inside Scoop, 2008) to further compliment the Dig It! exhibit. This was a new endeavor for SSSA having never worked with the non-academic audience in developing a book. Peer-reviews of this book included not only scientist but also students in order to make sure the book was attractive to them. Once the book was published and the website developed it became clear more outreach was needed. SSSA K12 Committee has attended both the National Science Teachers Association (since 2008) the USA Science and Engineering Festival (since 2010) with exhibits and workshops. It has cooperated and contributed to the American Geologic Institutes' Earth Science Week materials with brochures and lesson plans and with National Association of Conservation Districts by providing peer-review and distribution of materials. The most recent developments from the committee include a web redesign that is more student and teacher friendly, the development of a peer-review system to publish K12 Lesson Plans, and finally the publication of a new soils

    BioEYES, a nonprofit outreach program using zebrafish to excite and educate K-12 students about science and how to think and act like scientists, has been integrated into hundreds of under-resourced schools since 2002. During the week-long experiments, students raise zebrafish embryos to learn principles of development and genetics. We have analyzed 19,463 participating students' pre- and post-tests within the program to examine their learning growth and attitude changes towards science. We found that at all grade levels, BioEYES effectively increased students' content knowledge and produced favorable shifts in students' attitudes about science. These outcomes were especially pronounced in younger students. Having served over 100,000 students, we find that our method for providing student-centered experiences and developing long-term partnerships with teachers is essential for the growth and sustainability of outreach and school collaborations.

    This study was launched from a National Science Foundation GK-12 grant in which graduate fellows in Science, Technology, Engineering, and Mathematics (STEM) are placed in classrooms to engage K-12 students in STEM activities. The investigation explored whether the STEM Fellows' presence impacted the K-12 students' stereotypical image of a scientist. Since finding a valid instrument is critical, the study involved (1) determining the validity of the commonly administered Draw-A-Scientist Test (DAST) against a newly designed six-question survey and (2) using a combination of both instruments to determine what stereotypes are currently held by children. A pretest-posttest design was used on 485 students, grades 3-11, attending 6 different schools in suburban and rural Maine communities. A significant but low positive correlation was found between the DAST and the survey; therefore, it is imperative that the DAST not be used alone, but corroboration with interviews or survey questions should occur. Pretest results revealed that the children held common stereotypes of scientists, but these stereotypes were neither as extensive nor did they increase with the grade level as past research has indicated, suggesting that a shift has occurred with children having a broader concept of who a scientist can be. Finally, the presence of an STEM Fellow corresponded with decreased stereotypes in middle school and high school, but no change in elementary age children. More research is needed to determine whether this reflects resiliency in elementary children's perceptions or limitations in either drawing or in writing out their responses.

    2015-12-01

    Adolescents and emerging adults can provide dentists with many challenges. Little information is available on their perceptions of dental costs once they turn 18 and dentistry is no longer State-funded. The aim of this study was to explore the use of dental care by Southland students in years 12 and 13, their perceptions of the cost of four common dental procedures, self-related oral health and dental self-care habits, time off school related to dental problems, and knowledge and views regarding fluoride. After ethical approval, a 26-question survey was conducted of all Southland students in years 12 and 13. Data were statistically analysed in SPSS version 20 with the alpha value set at 0.05. The participation rate was 49.6%. Regular attendance for examinations was reported by 77.5% with non-attendance mainly related to attitudes around lack of importance or necessity. Reported dental attendance varied according to gender, ethnicity and decile rating of school attended. Although some were accurate in their estimations of dental costs, the standard deviation for all procedures was large. The majority thought that costs put people off going to the dentist. While 74.8% brushed their teeth at least twice daily, only 26.6% flossed regularly. Knowledge regarding fluoride was lacking. It may be advantageous to include education regarding costs of dental care with patients of this age. This may motivate them to improve their self-care and ensure that their oral health is of a high standard before their dental needs are no longer State-funded.

    The attendance mandate for the medical course in Melaka Manipal Medical College, Manipal, India was increased from 75% to 90% based on the assumption that the mandatory increase will improve the students' performance. To find out whether there is any correlation between class attendance and academic performance. This was an institution based retrospective analytical study. Students who have completed Phase I (first two and a half years) of the MBBS course were included in the study. Student marks and attendance, from the database were obtained from three random batches, each, from two clusters A and B respectively. Those who had a mandatory attendance requirement of 75% belonged to A (n = 243), and those who had a mandatory attendance percentage of 90% belonged to B (n = 360). Statistical analyses performed included, Pearson 2 tailed correlation to correlate class attendance with student performance; Cluster analysis to classify group average in a similarity matrix; t-test to determine significance of difference in percentage of students who attained 100% when the college changed mandatory attendance from 75% to 90%; Mann-Whitney test to find out if there was a better performance in university exam when attendance policy changed. There was a significant correlation between attendance and the students who passed in the University exam. The number of students in the pass category was maximum (>90%) compared to students in distinction and failed categories. Percentage of students with 100% attendance rose from 4% (n = 10) to 11% (n = 40) when the mandatory attendance was increased from 75% to 90%. Attendance policy correlated with better academic performance. Reducing absenteeism, probably contributed to the improved academic performance of the students. But the link between attendance and best and worst performances could not be predicted because of small numbers in every batch.

    Full Text Available Abstract Today students class attendance is become more important part for any organizationsinstitutions. The conventional method of taking attendance by calling names or signing on paper is very time consuming and insecure hence inefficient. This paper presents the manual students attendance management into computerized system for convenience or data reliability. So the system is developed by the integration of ubiquitous computing systems into classroom for managing the students attendance using RFID and fingerprint reader. The system is designed to implement an attendance management system based on RFID and fingerprint reader which students need to use their student identification card ID and their finger ID to success the attendance where only authentic student can be recorded the attendance during the class. In this system passive RFID tag and reader pairs are used to register the student ID cards individually and fingerprint reader is used for attendance. This system takes attendance electronically with the help of the RFID and finger print device and the records of the attendance are stored in a database. Students roll call percentages and their details are easily seenvia Graphical User Interface GUI. This system will have the required databases for students attendance teachers subjects and students details. This application is implemented by Microsoft Visual Studio and Microsoft SQL Server as IDE. C language is used to implement this system.

  1. Integrating local environmental research into K-12 science classrooms and the value of graduate student-educator partnerships

    Collaboration between researchers and K-12 educators enables an invaluable exchange of teaching philosophies and educational tools. Programs that partner graduate students with K-12 educators serve the dual purpose of training future educators and providing K-12 students with unique opportunities and perspectives. The benefits of this type of partnership include providing students with enhanced educational experiences and positive student-mentor relationships, training STEM graduate students in effective teaching strategies, and providing teachers with a firsthand resource for scientific information and novel educational materials. Many high school students have had little exposure to science beyond the classroom. Frequent interactions with "real-life" scientists can help make science more approachable and is an effective strategy for promoting science as a career. Here I describe my experiences and several lessons designed as a NSK GK-12 fellow. For example, a month-long unit on biogeochemical principles was framed as a crime scene investigation of a fish kill event in Hood Canal, Washington, in which students were given additional pieces of evidence to solve the mystery as they satisfied checkpoints in their understanding of key concepts. The evidence pieces included scientific plots, maps, datasets, and laboratory exercises. A clear benefit of this investigation-style unit is that students were able to learn the material at their individual pace. This structure allowed for a streamlined integration of differentiated materials such as simplified background readings or visual learning aids for struggling students or more detailed news articles and primary literature for more advanced students. Although the NSF GK-12 program has been archived, educators and researchers should pursue new partnerships, leveraging local and state-level STEM outreach programs with the goal of increasing national exposure of the societal benefits of such synergistic activities.

    2016-02-01

    Full Text Available Increasing student diversity in K-12 schools has gained attention in Japan and the US. In the US, racial diversity has historically shaped inequity in educational access and teacher quality. In Japan, regardless of its reputation for cultural homogeneity among its residents, issues surrounding student diversity have gained attention because of the increasing number of returnees—Japanese students raised overseas because of their parents’ expatriation. This paper compares and contrasts the diversity issues in K-12 school settings in both countries, and explores potential approaches to improve the accommodation of diversity in K-12 schools.

    Student attendance is thought to be an important factor in the academic performance of medical students, in addition to having important regulatory, policy, and financial implications for medical educators. However, this relationship has not been well evaluated within clinical learning environments. To evaluate the relationship between student attendance and academic performance in a medical student obstetrics/gynecology clinical rotation. A prospective cohort study of student attendance at clinical and tutorial-based activities during a full academic year (September 2011 to June 2012) within a publicly funded university teaching hospital in Dublin, Ireland. Students were expected to attend 64 activities (26 clinical activities and 38 tutorial-based activities) but attendance was not mandatory. All 147 fourth-year medical students who completed an 8-week obstetrics/gynecology rotation were included. Student attendance at clinical and tutorial-based activities, recorded using a paper-based logbook. The overall examination score (out of a possible 200 points) was obtained using an 11-station objective structured clinical examination (40 points), an end-of-year written examination comprising 50 multiple-choice questions (40 points) and 6 short-answer questions (40 points), and an end-of-year long-case clinical/oral examination (80 points). Students were required to have an overall score of 100 points (50%) and a minimum of 40 points in the long-case clinical/oral examination (50%) to pass. The mean attendance rate was 89% (range, 39%-100% [SD, 11%], n = 57/64 activities). Male students (84% attendance, P = .001) and students who failed an end-of-year examination previously (84% attendance, P = .04) had significantly lower rates. There was a positive correlation between attendance and overall examination score (r = 0.59 [95% CI, 0.44-0.70]; P year examination, and the timing of the rotation during the academic year.

    2016-01-01

    Many students graduate high school having never learned about the process and people behind modern science research. The BiteScis program addresses this gap by providing easily implemented lesson plans that incorporate the whos, whats, and hows of today's scienctific discoveries. We bring together practicing scientists (motivated graduate students from the selective communicating science conference, ComSciCon) with K-12 science teachers to produce, review, and disseminate K-12 lesson plans based on modern science research. These lesson plans vary in topic from environmental science to neurobiology to astrophysics, and involve a range of activities from laboratory exercises to art projects, debates, or group discussion. An integral component of the program is a series of short, "bite-size" articles on modern science research written for K-12 students. The "bite-size" articles and lesson plans will be made freely available online in an easily searchable web interface that includes association with a variety of curriculum standards. This ongoing program is in its first year with about 15 lesson plans produced to date.

    In 1995, a survey was conducted among students attending 69 Seventh-day Adventist (SDA) high schools within the United States and Canada. The survey assessed the extent that these students practiced sexual and drug-use behaviors which place them at risk for contracting or transmitting the human immunodeficiency virus (HIV). A total of 1,748 respondents enrolled in grades 9 through 12 completed questionnaires similar to the instrument used in the 1993 Youth Risk Behavior Survey (YRBS). Data were collected and compared to results from the 1993 YRBS. Students who attended SDA parochial schools reported lower rates of sexual intercourse compared to YRBS school counterparts (16.3% vs. 53.1%) and lower rates of all substances measured. Furthermore, respondents were more likely to engage in substance use and sexual intercourse if they had at least one parent who used tobacco, alcohol, or marijuana, as reported by the students.

    Selected K--12 public school science educators in 14 eastern North Carolina counties were surveyed to examine their perceptions of their undergraduate preparation programs with regard to instructing students with learning disabilities in the regular classroom. A quantitative study, this research examined science educator preparedness in instructing students with learning disabilities by evaluating educator perception in regard to mainstrearned and inclusive educational settings. Specifically, two null hypotheses were tested. Null hypothesis I stated a significant difference does not exist between selected North Carolina K--12 science educators' perceptions of their undergraduate teacher education preparation programs and their perceptions of their abilities to instruct students needing accommodations on behalf of their learning disabilities in mainstrearned or inclusive settings. Participants' responses to perception as well as value statements regarding opinions, adaptations, and undergraduate training with respect to mainstreaming and inclusion were evaluated through t-test analyses of 22 Likert-scale items. Null hypothesis 1 was not accepted because a statistically significant difference did exist between the educators' perceptions of their undergraduate training and their perceived abilities to instruct students with learning disabilities in mainstreamed or inclusive settings. Null hypothesis 2 stated a significant difference does not exist between selected North Carolina K--12 science educators' attained educational level; grade level currently taught, supervised or chaired; and years of experience in teaching science, supervising science education, and/or chairing science departments in selected North Carolina public schools and their opinions of their undergraduate teacher education program with regard to instructing students with learning disabilities in mainstreamed or inclusive educational settings. Null hypothesis 2 was evaluated through an analysis of

    The University of Texas Institute for Geophysics (UTIG) recognizes the value of providing educational opportunities to K-12 teachers who play a critical role in shaping the minds of young people who are the future of our science. To that end, UTIG established the "Texas Teachers in the Field" program in 2000 to formalize the participation of K-12 teachers in field programs that included UTIG scientists. In 2002, "Texas Teachers in the Field" evolved through UTIG's involvement in a University of Texas at Austin GK-12 project led by the Environmental Sciences Institute, which enabled UTIG to partner a subset of GK-12 Fellows with teachers participating in geophysical field programs. During the three years of the GK-12 project, UTIG successfully partnered four GK-12 Fellows with five K-12 teachers. The Fellows served as mentors to the teachers, as liaisons between UTIG scientists leading field programs and teachers and their students, and as resources in science, mathematics, and technology instruction. Specifically, Fellows prepared teachers and their students for the field investigations, supervised the design of individual Teacher Research Experience (TRE) projects, and helped teachers to develop standards-aligned curriculum resources related to the field program for use in their own classrooms, as well as broader distribution. Although all but one TRE occurred during the school year, Texas school districts and principals were willing to release teachers to participate because the experience and destinations were so extraordinary (i.e., a land-based program in Tierra del Fuego, Argentina; and research cruises to the Southeast Caribbean Sea and Hess Deep in the Pacific Ocean) and carried opportunities to work with scientists from around the world. This exceptional collaboration of GK-12 Fellows, K-12 teachers and research scientists enriches K-12 student learning and promotes greater enthusiasm for science. The level of mentoring, preparation and follow-up provided

    High-quality audiovisual recording technology enables medical students to listen to didactic lectures without actually attending them. The authors wondered whether in-person attendance affects how students evaluate lecturers. This is a retrospective review of faculty evaluations completed by first- and second-year medical students at the Ohio State University College of Medicine during 2009-2010. Lecture-capture technology was used to record all lectures. Attendance at lectures was optional; however, all students were required to complete lecturer evaluation forms. Students rated overall instruction using a five-option response scale. They also reported their attendance. The authors used analysis of variance to compare the lecturer ratings of attendees versus nonattendees. The authors included additional independent variables-year of student, student grade/rank in class, and lecturer degree-in the analysis. The authors analyzed 12,092 evaluations of 220 lecturers received from 358 students. The average number of evaluations per lecturer was 55. Seventy-four percent (n = 8,968 evaluations) of students attended the lectures they evaluated, whereas 26% (n = 3,124 evaluations) viewed them online. Mean lecturer ratings from attendees was 3.85 compared with 3.80 by nonattendees (P ≤ .05; effect size: 0.055). Student's class grade and year, plus lecturer degree, also affected students' evaluations of lecturers (effect sizes: 0.055-0.3). Students' attendance at lectures, year, and class grade, as well as lecturer degree, affect students' evaluation of lecturers. This finding has ramifications on how student evaluations should be collected, interpreted, and used in promotion and tenure decisions in this evolving medical education environment.

    The Lewis Center for Educational Research (LCER) and the Jet Propulsion Laboratory (JPL) collaborate in a K-12 educational project in which students conduct observations for several research programs led by radio astronomers. The Goldstone-Apple Valley Radio Telescope (GAVRT) program provides participating teachers with curriculum elements, based on the students' observing experiences, which support national and state academic standards. The current program is based on 2.2-GHz and 8.4-GHz radiometric observations of variable sources. The research programs monitor Jupiter, Uranus, and a selected set of quasars. The telescope is a decommissioned NASA Deep Space Network antenna at Goldstone, California. In the next three years, a second telescope will be added. This telescope will at least operate at the above frequencies as well as 6 GHz and 12 GHz. Possibly, it will operate in a continuous band from 1.2 GHz to 14 GHz. In either case, the telescope will be able to observe at least the 6.6-GHz and 12.2-GHz methanol maser lines. The success of the GAVRT program depends critically on the participation of scientists committed to the research who have the ability and enthusiasm for interacting with K-12 students, typically through teleconferences. The scientists will initially work with the LCER staff to create curriculum elements around their observing program.

    With new career openings in the geosciences expected and a large number of presently employed geoscientists retiring in the next decade there is a critical need for a new cadre of geoscientists to fill these positions. A project funded by the National Science Foundation titled K-12 Students, Teachers, Parents, Administrators and Higher Education Faculty: Partners Helping Rural Disadvantaged Students Stay on the Pathway to a Geoscience Career involving Wright State University and the Ripley, Lewis, Union, Huntington k-12 school district in Appalachian Ohio took led to dozens of seventh and eighth grade students traveling to Sandy Hook, New Jersey for a one week field experience to study oceanography with staff of the New Jersey Sea Grant Consortium. Teachers, parent chaperones, administrators and university faculty accompanied the students in the field. Teachers worked alongside their students in targeted professional development during the weeklong field experience. During the two academic years of the project, both middle school and high school teachers received professional development in Earth system science so that all students, not just those that were on the summer field experience could receive enhanced science learning. All ninth grade high school students were given the opportunity to take a high school/college dual credit Earth system science course. Community outreach provided widespread knowledge of the project and interest among parents to have their children participate. In addition, ninth grade students raised money themselves to fund a trip to the International Field Studies Forfar Field Station on Andros Island, Bahamas to study a tropical aquatic system. Students who before this project had never traveled outside of Ohio are currently discussing ways that they can continue on the pathway to a geoscience career by applying for internships for the summer between their junior and senior years. These are positive steps towards taking charge of their

    To understand perceptions of faculty and students about attendance policies in baccalaureate nursing programs. Classroom attendance is an issue of debate across academic disciplines. A mixed-methods study was conducted using qualitative data from a stratified random sample of 65 accredited baccalaureate nursing programs; 591 students and 91 faculty from 19 schools responded. Sixty-two percent of faculty thought students who missed class exhibited unprofessional behavior; 69 percent believed students who missed class were less successful in the clinical setting. Students (57 percent) and faculty (66 percent) believed there should be an attendance policy. Twenty-nine students reported needing a break in workload (16.8 percent) or did not find class time valuable (11.8 percent). Variability exists in student and faculty beliefs regarding attendance policies. Understanding these viewpoints and utilizing creative teaching approaches will facilitate learning and create an environment of teamwork and mutual respect.

    Billings-Gagliardi, Susan; Mazor, Kathleen M

    2007-10-01

    This study explored whether first-year medical students make deliberate decisions about attending nonrequired lectures. If so, it sought to identify factors that influence these decisions, specifically addressing the potential impact of electronic materials. Medical students who completed first-year studies between 2004 and 2006 responded to an open-ended survey question about their own lecture-attendance decisions. Responses were coded to capture major themes. Students' ratings of the electronic materials were also examined. Most respondents made deliberate attendance decisions. Decisions were influenced by previous experiences with the lecturer, predictions of what would occur during the session itself, personal learning preferences, and learning needs at that particular time, with the overriding goal of maximizing learning. Access to electronic materials did not influence students' choices. Fears that the increasing availability of technology-enhanced educational materials has a negative impact on lecture attendance seem unfounded.

    Using the empirical powers of theories of intersectionality, the study investigates the association between students' demographics (such as gender identity, race, ethnicity, age, and socioeconomic status) and sexual violence victimization. An anonymous survey was employed to collect data from a cluster random sample of 966 students attending face-to-face courses at a midsize urban nonresidential campus. The empirical findings suggest that being older and female are the only statistically significant factors in the analysis. As the first attempt to focus on students attending nonresidential programs in the United States, the study presents implications for policy and program implementation to include issues pertinent to students' diversity to better respond to students' risk of victimization.

    Full Text Available School personnel currently lack an effective method to pattern and visually interpret disaggregated achievement data collected on students as a means to help inform decision making. This study, through the examination of longitudinal K-12 teacher assigned grading histories for entire cohorts of students from a school district (n=188, demonstrates a novel application of hierarchical cluster analysis and pattern visualization in which all data points collected on every student in a cohort can be patterned, visualized and interpreted to aid in data driven decision making by teachers and administrators. Additionally, as a proof-of-concept study, overall schooling outcomes, such as student dropout or taking a college entrance exam, are identified from the data patterns and compared to past methods of dropout identification as one example of the usefulness of the method. Hierarchical cluster analysis correctly identified over 80% of the students who dropped out using the entire student grade history patterns from either K-12 or K-8.

    2012-12-01

    As part of the Long Term Ecological Research (LTER) program, the Harvard Forest in Petersham, Massachusetts seeks to train the next generation of researchers, by involving K-12 grade students and their teachers in hands-on, field-based, ecological research in their own schoolyard and community. Students learn to collect data on important long-term ecological issues and processes. Student data are then shared on the Harvard Forest website. To prepare teachers for project protocols, teachers are given direct access to Harvard ecologists with professional development workshops and on-line resources. With the Harvard Forest Schoolyard LTER program, students can participate in three different research projects focusing on phenology, invasive insects, and vernal pools. Teachers attend the Summer Institute for Teachers to learn project content and methods. They return in fall to participate in one of three levels of data workshops to learn how to input, manage, and analyze project data. In the spring, teachers again meet with the Harvard ecologists about project protocols, and to share, through a series of teacher presentations, the ways these project themes are being integrated into class curricula. These professional development opportunities result in long term collaborative partnerships with local schools and the Harvard Forest LTER. In addition to the LTER Schoolyard Ecology Program, the Harvard Forest has supported a successful Research Experience for Teachers (RET) program for the last six years. Throughout the summer, teachers work on research projects alongside Harvard Forest and affiliated scientists, post-docs, graduate students, and REU's (Research Experience for Undergraduates). The RET program provides teachers with the opportunity to build scientific knowledge, develop an understanding of research methods, and translate their new knowledge and experiences into cutting edge classroom lessons.

  3. A phenomenological case study concerning science teacher educators' beliefs and teaching practices about culturally relevant pedagogy and preparing K-12 science teachers to engage African American students in K-12 science

    Science.gov (United States)

    Underwood, Janice Bell

    Due to the rising diversity in today's schools, science teacher educators (STEs) suggest that K-12 teachers must be uniquely prepared to engage these students in science classrooms. Yet, in light of the increasing white-black science achievement gap, it is unclear how STEs prepare preservice teachers to engage diverse students, and African Americans in particular. Therefore, the purpose of this study was to find out how STEs prepare preservice teachers to engage African American students in K-12 science. Thus, using the culturally relevant pedagogy (CRP) framework, this phenomenological case study explored beliefs about culturally relevant science teaching and the influence of reported beliefs and experiences related to race on STEs' teaching practices. In the first phase, STE's in a mid-Atlantic state were invited to participate in an electronic survey. In the second phase, four participants, who were identified as exemplars, were selected from the survey to participate in three semi-structured interviews. The data revealed that STEs were more familiar with culturally responsive pedagogy (CResP) in the context of their post-secondary classrooms as opposed to CRP. Further, most of the participants in part one and two described modeling conventional ways they prepare their preservice teachers to engage K-12 students, who represent all types of diversity, without singling out any specific race. Lastly, many of the STEs' in this study reported formative experiences related to race and beliefs in various manifestations of racism have impacted their teaching beliefs and practices. The findings of this study suggest STEs do not have a genuine understanding of the differences between CRP and CResP and by in large embrace CResP principles. Secondly, in regards to preparing preservice teachers to engage African American students in science, the participants in this study seemed to articulate the need for ideological change, but were unable to demonstrate pedagogical changes

  7. Student nurse absenteeism in higher education: An argument against enforced attendance.

    Lipscomb, Martin; Snelling, Paul C

    2010-08-01

    Unauthorised student nurse absenteeism in higher education troubles many university lecturers. Anecdotally, absenteeism is occasionally raised as an issue by attending students who resent others "getting away" with non-attendance and some policy documents appear to suggest that attendance should be mandated. This paper argues against enforced attendance in higher education and challenges those who would mandate attendance to explain and justify their position. Drawing on a range of nursing and non-nursing material we here discuss some of the literature on attendance, absenteeism, effort or time spent in study and grade attainment. Informed by this admittedly partial review we maintain that the evidence linking grade attainment with attendance and study effort is less conclusive than intuition might initially suggest. We note that enforcing attendance apparently runs counter to important pedagogic (humanistic and androgogic) principles. We propose that responses to absenteeism cannot be separated from questions of 'harm' and we suggest that lecturers should refrain from associating non-attendance with unprofessional behaviour and poor professionalization.

  12. Science Communication versus Science Education: The Graduate Student Scientist as a K-12 Classroom Resource

    Science.gov (United States)

    Strauss, Jeff; Shope, Richard E., III; Terebey, Susan

    2005-01-01

    Science literacy is a major goal of science educational reform (NRC, 1996; AAAS, 1998; NCLB Act, 2001). Some believe that teaching science only requires pedagogical content knowledge (PCK). Others believe doing science requires knowledge of the methodologies of scientific inquiry (NRC, 1996). With these two mindsets, the challenge for science educators is to create models that bring the two together. The common ground between those who teach science and those who do science is science communication, an interactive process that galvanizes dialogue among scientists, teachers, and learners in a rich ambience of mutual respect and a common, inclusive language of discourse . The dialogue between science and non-science is reflected in the polarization that separates those who do science and those who teach science, especially as it plays out everyday in the science classroom. You may be thinking, why is this important? It is vital because, although not all science learners become scientists, all K-12 students are expected to acquire science literacy, especially with the implementation of the No Child Left Behind Act of 2001 (NCLB). Students are expected to acquire the ability to follow the discourse of science as well as connect the world of science to the context of their everyday life if they plan on moving to the next grade level, and in some states, to graduate from high school. This paper posits that science communication is highly effective in providing the missing link for K-12 students cognition in science and their attainment of science literacy. This paper will focus on the "Science For Our Schools" (SFOS) model implemented at California State Univetsity, Los Angeles (CSULA) as a project of the National Science Foundation s GK-12 program, (NSF 2001) which has been a huge success in bridging the gap between those who "know" science and those who "teach" science. The SFOS model makes clear the distinctions that identify science, science communication, science

    The Center for Microbial Oceanography: Research and Education (C-MORE) is a NSF Science and Technology Center based at the University of Hawaii. The C-MORE education and outreach program offers a variety of resources and professional development opportunities for science educators, including online resources, participation in oceanography research cruises, teacher-training workshops, mini-grants to incorporate microbial oceanography-related content and activities into their classroom and, most recently, C- MORE science kits. C-MORE science kits provide hands-on classroom, field, and laboratory activities related to microbial oceanography for K-12 students. Each kit comes with complete materials and instructions, and is available free of charge to Hawaii's public school teachers. Several kits are available nationwide. C-MORE science kits cover a range of topics and technologies and are targeted at various grade levels. Here is a sampling of some available kits: 1) Marine Murder Mystery: The Case of the Missing Zooxanthellae. Students learn about the effect of climate change and other environmental threats on coral reef destruction through a murder-mystery experience. Participants also learn how to use DNA to identify a suspect. Grades levels: 3-8. 2) Statistical sampling. Students learn basic statistics through an exercise in random sampling, with applications to microbial oceanography. The laptops provided with this kit enable students to enter, analyze, and graph their data using EXCEL. Grades levels: 6-12. 3) Chlorophyll Lab. A research-quality fluorometer is used to measure the chlorophyll content in marine and freshwater systems. This enables students to compare biomass concentrations in samples collected from various locations. Grades levels: 9-12. 4) Conductivity-Temperature-Depth (CTD). Students predict how certain variables (e.g., temperature, pressure, chlorophyll, oxygen) vary with depth. A CTD, attached to a laptop computer, is deployed into deep water

In addition, there is little published evidence available to medical educators regarding the use of attendance monitoring systems. The aim of this study was to evaluate the opinions of students and staff about the use of a paper-based student logbook to record student attendance across all clinical and classroom-based learning activities within an undergraduate clinical rotation in obstetrics and gynecology (OBGYN. Methods: Each student undertaking the clinical rotation in OBGYN was required to complete a paper-based logbook in a booklet format that listed every clinical and classroom-based activity that the student was expected to attend. A cross-sectional survey evaluating the acceptability, practicality, and effect on access to learning opportunities of using the logbook was undertaken. The survey was conducted among all medical students who completed their OBGYN rotation over a full academic year and staff who taught on the program. Results: The response rate was 87% (n=128/147 among students and 80% (n=8/10 among staff. Monitoring attendance was widely acceptable to students (n=107/128, 84% and staff (n=8/8, 100%.

    Full Text Available The calculation of the level of attendance is very important, because one indicator of a person's credibility can be seen from the level of attendance. For example, at a university, data about the level of attendance of a student in a lecture is very important as one of components in the assessment. The manual presence system is considered less effective. This research presents the draft of presence system using bar codes (barcodes as input data representing the attendance. The presence system is supported by three main components, those are a bar code found on the student card (KTM, a CCD barcode scanner series and a CD-108E computer. Management of attendance list using this system allows for optimization of functions of KTM. The presence system has been tested with several KTM through a variety of distances and positions of the barcode scanner barcode. The test results is obtained at ideal position for reading a barcode when a barcode scanner is at 2 cm from the object with 90 degree. At this position the level of accuracy reach 100%.

    Weight bias can negatively impact health, and schools may be risky environments for students with obesity. We aimed to explore teachers' perceptions of the school experiences and academic challenges of students with obesity. We conducted interviews with 22 teachers in the Northeast, mid-Atlantic, and Midwest in July-August 2014. All interviews were transcribed verbatim, coded, and analyzed for important themes by two researchers using the immersion/crystallization approach. Most teachers felt that students with obesity were more likely to have academic difficulties. Two main perceptions of the reasons for these difficulties emerged: (1) obesity led to lower self-esteem that caused students to participate less, and (2) poorer nutrition, increased screen time, and reduced physical activity were simultaneously causing obesity and poorer academic performance. A few teachers described colleagues who felt students with obesity were not as motivated to work hard in school as their peers. Many teachers described school health promotion efforts focused on weight reduction that could exacerbate weight stigma and risk of disordered eating. Students with obesity, particularly girls, may be at risk for negative social and academic experiences in K-12 schools and may be perceived as struggling academically by their teachers.

    The Initiating New Science Partnerships in Rural Education (INSPIRE) program at Mississippi State University (MSU), funded by the NSF Graduate STEM Fellows in K-12 Education (GK12) program, focuses on the advancement of Earth and Space science education in K-12 classrooms. INSPIRE is currently in its second year of partnering ten graduate students from the STEM fields of Geosciences, Engineering and Chemistry at MSU with five teachers from local, rural school districts. The five year project serves to increase inquiry and technology experiences in science and math while enhancing graduate student's communication skills as they create interactive lessons linking their STEM research focus to the state and national standards covered in the classrooms. Each graduate student is responsible for the development of two lessons each month of the school year that are then published on the INSPIRE project webpage, www.gk12.msstate.edu, where they are a free resource for any K-12 classroom teacher seeking innovative activities for their classrooms. Many of the participating teachers and graduate students share activities developed with non-participating teachers, expanding INSPIRE's outreach throughout the local community. Numerous challenges were met during the formation of the program as well as throughout the first year in which the project management team worked together to find solutions ensuring that INSPIRE maintained successful partnerships for all involved. Proposed solutions of the following key components were identified by INSPIRE through the development, implementation, and continuous evaluation (internal and external) of the first year of the program as areas that can pose challenges to the construction of strong relationships between STEM research and K-12 classrooms: initializing the partnerships with the K-12 classrooms and STEM graduate fields at the university; maintaining strong partnerships; providing appropriate training and support; developing sound

    The National Science Foundation funded project K-12 Students, Teachers, Parents, Administrators and Higher Education Faculty: Partners Helping Rural Disadvantaged Students Stay on the Pathway to a Geoscience Career is a research-based proof of concept track 1 pilot project that tests the effectiveness of an innovative model for simultaneous K-12 teacher professional development, student learning and workforce development. The project builds a network of science experiences designed to keep eighth and ninth grade students from the Ripley, Union, Lewis, Huntington (RULH) Ohio school district on the path to a geoscience career. During each summer of the ongoing two-year project teams of RULH students, parents, teachers, administrators and college faculty traveled to the facilities of the New Jersey Sea Grant Consortium at Sandy Hook, New Jersey to study science from an Earth system perspective. Teachers had the opportunity to engage in professional development alongside their students. Parents participated in the science activities alongside their children. Administrators interacted with students, parents and their teachers and saw them all learning science in an engaging, collaborative setting. During the first academic year of the project professional development was provided to RULH teachers by a team of university scientists and geoscience educators from the Earth System Science Education Alliance (ESSEA), a National Science Foundation funded project. Teachers selected for professional development were from science disciplines, mathematics, language arts and civics. The teachers selected, taught and assessed ESSEA Earth system science modules to all eighth and ninth grade students, not just those that were selected to go on the summer trips to New Jersey. In addition, all ninth grade RULH students had the opportunity to take a course that includes Earth system science concepts that will earn them both high school and college science credits.

    Student attendance in American public schools is a critical factor in securing limited operational funding. Student and teacher attendance influence academic performance. Limited data exist on indoor air and environmental quality (IEQ) in schools, and how IEQ affects attendance, health, or performance. This study explored the association of student absence with measures of indoor minus outdoor carbon dioxide concentration (dCO(2)). Absence and dCO(2) data were collected from 409 traditional and 25 portable classrooms from 22 schools located in six school districts in the states of Washington and Idaho. Study classrooms had individual heating, ventilation, and air conditioning (HVAC) systems, except two classrooms without mechanical ventilation. Classroom attributes, student attendance and school-level ethnicity, gender, and socioeconomic status (SES) were included in multivariate modeling. Forty-five percent of classrooms studied had short-term indoor CO(2) concentrations above 1000 p.p.m. A 1000 p.p.m. increase in dCO(2) was associated (P student absence. Annual ADA was 2% higher (P student attendance, and occupant health and student performance, with longer term indoor minus outdoor CO(2) concentrations and more accurately measured ventilation rates. If our findings are confirmed, improving classroom ventilation should be considered a practical means of reducing student absence. Adequate or enhanced ventilation may be achieved, for example, with educational training programs for teachers and facilities staff on ventilation system operation and maintenance. Also, technological interventions such as improved automated control systems could provide continuous ventilation during occupied times, regardless of occupant thermal comfort demands.

    The Science Education Resource Center (SERC) has created a portal to information for K12 educators to provide high-quality grade level appropriate materials from a wide variety of projects and topics. These materials were compiled across the SERC site, showcasing materials that were created for, or easily adaptable to, K12 classrooms. This resource will help support implementation of Next Generation Science Standards by assisting educators in finding innovative resources to address areas of instruction that are conceptually different than previous national and state science standards. Specifically, the K12 portal assists educators in learning about approaches that address the cross-cutting nature of science concepts, increasing students quantitative reasoning and numeracy skills, incorporating technology such as GIS in the classroom, and by assisting educators of all levels of K12 instruction in using relevant and meaningful ways to teach science concepts. The K12 portal supports educators by providing access to hundreds of teaching activities covering a wide array of science topics and grade levels many of which have been rigorously reviewed for pedagogic quality and scientific accuracy. The portal also provides access to web pages that enhance teaching practices that help increase student's system thinking skills, make lectures interactive, assist instructors in conducting safe and effective indoor and outdoor labs, providing support for teaching energy and climate literacy principles, assisting educators in addressing controversial content, provide guidance in engaging students affective domain, and provides a collection of tools for making teaching relevant in 21st century classrooms including using GIS, Google Earth, videos, visualizations and simulations to model and describe scientific concepts.

    Truth telling or transmitting bad news is a problem that all doctors must frequently face. The purpose of this cross-sectional study was to investigate if medical students' opinions of truth telling differed from their observations of attending physicians' actual clinical practice. The subjects were 275 medical clerks/interns at a medical center in northern Taiwan. Data were collected on medical students' opinions of truth telling, their observations of physicians' clinical practice, students' level of satisfaction with truth telling practiced by attending physicians, and cancer patients' distress level when they were told the truth. Students' truth-telling awareness was significantly higher than the clinical truth-telling practice of attending physicians (pmedical students' opinions on truth telling and attending physicians' actual clinical practice. More research is needed to objectively assess physicians' truth telling in clinical practice and to study the factors affecting the method of truth telling used by attending physicians in clinical practice.

  18. Good Morning from Barrow, Alaska! Helping K-12 students understand the importance of research

    Science.gov (United States)

    Shelton, M.

    2010-12-01

    This presentation focuses on how an educator experiences scientific research and how those experiences can help foster K-12 students’ understanding of research being conducted in Barrow, Alaska. According to Zhang and Fulford (1994), real-time electronic field trips help to provide a sense of closeness and relevance. In combination with experts in the field, the electronic experience can help students to better understand the phenomenon being studied, thus strengthening the student’s conceptual knowledge (Zhang & Fulford, 1994). During a seven day research trip to study the arctic sea ice, five rural Virginia teachers and their students participated in Skype sessions with the participating educator and other members of the Radford University research team. The students were able to view the current conditions in Barrow, listen to members of the research team describe what their contributions were to the research, and ask questions about the research and Alaska in general. Collaborations between students and scientist can have long lasting benefits for both educators and students in promoting an understanding of the research process and understanding why our world is changing. By using multimedia venues such as Skype students are able to interact with researchers both visually and verbally, forming the basis for students’ interest in science. A learner’s level of engagement is affected by the use of multimedia, especially the level of cognitive processing. Visual images alone do no promote the development of good problem solving skills. However, the students are able to develop better problem solving skills when both visual images and verbal interactions are used together. As students form higher confidence levels by improving their ability to problem solve, their interest in science also increases. It is possible that this interest could turn into a passion for science, which could result in more students wanting to become scientists or science teachers.

    The Polaris Project is a unique undergraduate education, research, and outreach initiative that examines global climate change in the Siberian Arctic. The program focuses on permafrost and carbon processes in the boreal and tundra ecosystems of the Kolyma Watershed, the largest watershed underlain by continuous permafrost. Each summer, a diverse group of undergraduate students and faculty mentors spends one month living on the Kolyma River, developing independent projects that engage the students directly in the biogeosciences through authentic scientific research experiences in remote field sites. In all cases the student projects contribute to the overall goal of the Polaris Project to investigate the transport and transformations of carbon and nutrients as they move among terrestrial and aquatic ecosystems and the atmosphere. Through the use of online interactive ArcGIS maps the students share their experiences and learning, while posing questions in a format that can be used to engage K-12 learners in the classroom. By embedding information; including databases, photographs and video, informational text, and geospatial data; into user-friendly maps the Polaris Project students will "tell the story" of studying climate change in the Siberian tundra in a way that allows the users to explore climate science through inquiry and web-map based investigation. Through performance expectation topics including Weather and Climate, Interactions, Earth's Systems, and Human impacts, this investigation uses consideration of the vast amounts of ancient organic matter locked up in permafrost in the region, and concerns about the fate of this ancient organic carbon as temperatures warm and permafrost thaws, to make K-12 climate change connections with the Next Generation Science Standards (NGSS).

    It is widely accepted that students in Japan sleep fewer hours than what they actually need. However, epidemiological data on sleep habits among students are scarce. The sleep habits and related problems among 1650 students in Akita prefecture were studied. The results revealed that schoolchildren attending elementary schools seemed to sleep for a sufficient number of hours, whereas students attending junior or senior high schools were not sleeping enough. In particular, approximately half of the students attending senior high schools answered that they slept 6 h or less on weekdays and nodded off during classes more than twice a week.

    Buettner, Cynthia K; Debies-Carl, Jeffrey S

    2012-07-01

    This study explored the relationship between bonding and bridging social capital and college student attendance at alcohol-present parties, a common method for building informal social networks. A random sample of students (n = 6,291; 52% female) from a large public midwestern university completed a survey regarding their alcohol use and party-related behaviors on targeted weekends. The survey also included questions regarding students' living arrangements, romantic relationships, and membership in student and community organizations. Based on a dichotomous logistic regression analysis, we concluded that the act of attending parties largely serves as a complement to, rather than a substitute for, more conventional and formal social capital. Membership in bonding groups is associated with increased odds of party attendance, and bridging exerts no direct effect on party attendance. However, bridging capital does mitigate the effect of bonding capital, reducing its apparent tendency to promote or contribute to partying. Off-campus parties may offer an informal supplement to more conventional social capital as students establish themselves in their new context. These findings may have implications for structural decisions (e.g., number of roommates) as well as the design of context-based prevention programs that address students' need to quickly build social capital without exposing both themselves and the students around them to the harms associated with high-risk drinking.

    Simple water quality test kits were used in a series of K-12 classrooms to demonstrate scientific processes and to motivate learning in K-12 students. While focused on student learning, this project also allowed collection of regional data on groundwater quality (primarily nitrate) in the study area. The project consisted of development and administration of a weeklong groundwater quality unit introduced to K-12 schools in northern Indiana and taught by a graduate student in an engineering discipline. The structure of the week started with an introduction to basic groundwater concepts modified for the specific grade level; for this project the students ranged from grades 4-12. In addition to groundwater basics, the purpose of the collection of the water quality data, as well as relevance to the research of the graduate student, were outlined. The students were then: (i) introduced to two simple water quality testing methods for nitrates, (ii) required to hypothesize as to which method will likely be "better" in application, and (iii) asked to practice using these two methods under laboratory conditions. Following practice, the students were asked to discuss their hypotheses relative to what was observed during the practice focusing on which testing method was more accurate and/or precise. The students were then encouraged to bring water samples from their home water system (many of which are on private wells) to analyze within groups. At the end of the week, the students shared their experience in this educational effort, as well as the resulting nitrate data from numerous groundwater wells (as collected by the students). Following these discussions the data were added to an online database housed on a wiki sponsored by the Notre Dame Extended Research Community (http://wellhead.michianastem.org/home). These data were plotted using the free service MapAList to visually demonstrate to the students the spatial distribution of the data and how their results have

    Full Text Available In an exploratory study (Note 1 of the role of salary level and other factors in motivating undergraduate math, science, and technology majors to consider a career as a K-12 teacher, the salary level students said would motivate them to consider a career in teaching was related to the salary expected in their chosen non-teaching occupation, but not to three of the Big 5 personality dimensions of extroversion, agreeableness, and openness, nor concern for others or career risk aversion. An annual starting salary 45% above the local average would attract 48% of the sophomore students and 37% of the juniors. Focus group results suggested that low pay was an important reason for not considering K-12 teaching, but that perceived job demands and abilities and interests were also important reasons for not being attracted to a teaching career.

    2001-05-01

    Reducing the discrepancy between the dynamic science that researchers experience and the static fact-driven science education in which k-12 students participate at school is an important component to national science education reform. Scientist-student partnerships (SSPs) involving whole classes in Earth systems research provide a solution to this problem, but existing models have often lacked rigorous scientific data quality control and/or evaluation of pedagogical effectiveness. The Paleontological Research Institution has been prototyping two SSPs with an eye toward establishing protocols to insure both scientific and educational quality of the partnership. Data quality analysis involves making statistical estimates of data accuracy and employing robust statistical techniques for answering essential questions with noisy data. Educational evaluation takes into account affective variables, such as student motivation and interest, and compares the relative pedagogical effectiveness of SSPs with more traditional hands-on activities. Paleontology is a natural subject for scientist-student partnerships because of its intrinsic appeal to the general public, and because its interdisciplinary content serves as a springboard for meeting science education standards across the physical and life sciences. The "Devonian Seas" SSP involves classes in identifying fossil taxa and assessing taphonomic characteristics from Devonian-aged Hamilton Group shales in Central New York. The scientific purpose of the project is to establish at high stratigraphic resolution the sequence of dysoxic biofacies composition, which will shed light on the sensitivity of epeiric sea communities to environmental (e.g., sea level) changes. The project is undertaken in upper elementary school and secondary school Earth science classes, and in some cases has involved field-based teacher training and collection of samples. Students in small teams collaborate to identify taxa within the samples, then

    Science.gov (United States)

    Spence, Anne

    2013-03-01

    Engineers rely on physicists as well as other scientists and mathematicians to explain the world in which we live. Engineers take this knowledge of the world and use it to create the world that never was. The teaching of physics and other sciences as well as mathematics is critical to maintaining our national workforce. Science and mathematics education are inherently different, however, from engineering education. Engineering educators seek to enable students to develop the habits of mind critical for innovation. Through understanding of the engineering design process and how it differs from the scientific method, students can apply problem and project based learning to solve the challenges facing society today. In this talk, I will discuss the elements critical to a solid K-12 engineering education that integrates science and mathematics to solve challenges throughout the world.

    Although class attendance is linked to academic performance, questions remain about what determines students' decisions to attend or miss class. In addition to the constructs of a common decision-making model, the theory of planned behaviour, the present study examined the influence of student role identity and university student (in-group) identification for predicting both the initiation and maintenance of students' attendance at voluntary peer-assisted study sessions in a statistics subject. University students enrolled in a statistics subject were invited to complete a questionnaire at two time points across the academic semester. A total of 79 university students completed questionnaires at the first data collection point, with 46 students completing the questionnaire at the second data collection point. Twice during the semester, students' attitudes, subjective norm, perceived behavioural control, student role identity, in-group identification, and intention to attend study sessions were assessed via on-line questionnaires. Objective measures of class attendance records for each half-semester (or 'term') were obtained. Across both terms, students' attitudes predicted their attendance intentions, with intentions predicting class attendance. Earlier in the semester, in addition to perceived behavioural control, both student role identity and in-group identification predicted students' attendance intentions, with only role identity influencing intentions later in the semester. These findings highlight the possible chronology that different identity influences have in determining students' initial and maintained attendance at voluntary sessions designed to facilitate their learning. ©2010 The British Psychological Society.

  20. Females and STEM: Determining the K-12 Experiences that Influenced Women to Pursue STEM Fields

    Science.gov (United States)

    Petersen, Anne Marie

    In the United States, careers in the fields of Science, Technology, Engineering, and Mathematics (STEM) are increasing yet there are not enough trained personnel to meet this demand. In addition, of those that seek to pursue STEM fields in the United States, only 26% are female. In order to increase the number of women seeking STEM based bachelor's degrees, K-12 education must provide a foundation that prepares students for entry into these fields. The purpose of this phenomenological study was to determine the perceived K-12 experiences that influenced females to pursue a STEM field. Twelve college juniors or seniors seeking a degree in Biology, Mathematics, or Physics were interviewed concerning their K-12 experiences. These interviews were analyzed and six themes emerged. Teacher passion and classroom characteristics such as incorporating challenging activities played a significant role in the females' decisions to enter STEM fields. Extra-curricular activities such as volunteer and mentor opportunities and the females' need to benefit others also influenced females in their career choice. Both the formal (within the school) and informal (outside of the traditional classroom) pipeline opportunities that these students encountered helped develop a sense of self-efficacy in science and mathematics; this self-efficacy enabled them to persist in pursuing these career fields. Several participants cited barriers that they encountered in K-12 education, but these barriers were primarily internal as they struggled with overcoming self-imposed obstacles in learning and being competitive in the mathematics and science classrooms. The experiences from these female students can be used by K-12 educators to prepare and encourage current female students to enter STEM occupations.

    2004-12-01

    The publication of countless reports documenting the dismal state of science education in the 1980s, and the Third International Mathematics and Science Study (TIMMS) report (1996) called for a wider involvement of the scientific community in K-12 education and outreach. Improving science education will not happen without the collaboration of educators and scientists working in a coordinated manner and it requires a long-term, continuous effort. To contribute effectively to K-12 education all scientists should refer to the National Science Education Standards, a set of policies that guide the development of curriculum and assessment. Ocean scientists can also specifically refer to the COSEE recommendations (www.cosee.org) that led to the creation of seven regional Centers for Ocean Sciences Education Excellence. Scientists can get involved in K-12 education in a multitude of ways. They should select projects that will accommodate time away from their research and teaching obligations, their talent, and their interest but also contribute to the education reform. A few examples of effective involvement are: 1) collaborating with colleagues in a school of education that can lead to better education of all students and future teachers, 2) acting as a resource for a national program or a local science fair, 3) serving on the advisory board of a program that develops educational material, 4) speaking out at professional meetings about the value of scientists' involvement in education, 5) speaking enthusiastically about the teaching profession. Improving science education in addition to research can seem a large, overwhelming task for scientists. As a result, focusing on projects that will fit the scientist's needs as well as benefit the science reform is of prime importance. It takes an enormous amount of work and financial and personnel resources to start a new program with measurable impact on students. So, finding the right opportunity is a priority, and stepping

    Streptococcus salivarius K12 (BLIS K12) is a probiotic strain strongly antagonistic to the growth of Streptococcus pyogenes, the most important bacterial cause of pharyngeal infections in humans. Shown to colonize the oral cavity and to be safe for human use, BLIS K12 has previously been reported to reduce pharyngo-tonsillitis episodes in children or adults known to have experienced recurrent streptococcal infection. The present study was focussed upon evaluating the role of BLIS K12 in the control of streptococcal disease and acute otitis media in children attending the first year of kindergarten. By randomization, 222 enrolled children attending the first year of kindergarten were divided into a treated group (N = 111) receiving for 6 months a daily treatment with BLIS K12 (Bactoblis®) and a control group (N = 111) who were monitored as untreated controls. During the 6 months of treatment and 3 months of follow-up, the children were evaluated for treatment tolerance, and for episodes of streptococcal pharyngo-tonsillitis, scarlet fever and acute otitis media. During the 6-month trial (N = 111 per group) the incidence of streptococcal pharyngo-tonsillitis, scarlet fever and acute otitis media was approximately 16%, 9% and 44% respectively in the treated group and 48%, 4% and 80% in the control group. During the 3-months follow-up (N = 29 per group) the corresponding rates of infection were 15%, 0% and 12% in the treated group and 26%, 6% and 36% in the controls. No apparent side effects were detected in the treated group either during treatment or follow-up. All of the enrolled children completed the study. The daily administration of BLIS K12 to children attending their first year of kindergarten was associated with a significant reduction in episodes of streptococcal pharyngitis and acute otitis media. No protection against scarlet fever was detected.

    2016-01-01

    Many U.S. schools use visible security measures (security cameras, metal detectors, security personnel) in an effort to keep schools safe and promote adolescents' academic success. This study examined how different patterns of visible security utilization were associated with U.S. middle and high school students' academic performance, attendance, and postsecondary educational aspirations. The data for this study came from two large national surveys--the School Crime Supplement to the National Crime Victimization Survey (N = 38,707 students; 51% male, 77% White, MAge = 14.72) and the School Survey on Crime and Safety (N = 10,340 schools; average student composition of 50% male, 57% White). The results provided no evidence that visible security measures had consistent beneficial effects on adolescents' academic outcomes; some security utilization patterns had modest detrimental effects on adolescents' academic outcomes, particularly the heavy surveillance patterns observed in a small subset of high schools serving predominantly low socioeconomic students. The findings of this study provide no evidence that visible security measures have any sizeable effects on academic performance, attendance, or postsecondary aspirations among U.S. middle and high school students.

    Several science education researchers have led assessment efforts that provide strategies particularly useful for evaluating the threedimensional learning that is central to NGSS (DeBarger, A. H., Penuel, W. R., Harris, C. J., Kennedy, C. K., 2016; Knight, A. M. & McNeill, K. L., 2015; McNeill, K.

One of the basic premises of these researchers is that, "Assessment is a practice of argument from evidence based on what students say, do, and write" and that "the classroom is the richest place to gather evidence of what students know (Penuel, W., 2016). The implementation of the NGSS in Earth System Science provides a unique opportunity for geoscience education researchers to study student learning and contribute to the development of this research as well as for geoscience educators to apply these approaches and strategies in their own work with K12 inservice and preservice educators.

  17. Using Scientific Visualizations to Enhance Scientific Thinking In K-12 Geoscience Education

    Science.gov (United States)

    Robeck, E.

    2016-12-01

    The same scientific visualizations, animations, and images that are powerful tools for geoscientists can serve an important role in K-12 geoscience education by encouraging students to communicate in ways that help them develop habits of thought that are similar to those used by scientists. Resources such as those created by NASA's Scientific Visualization Studio (SVS), which are intended to inform researchers and the public about NASA missions, can be used in classrooms to promote thoughtful, engaged learning. Instructional materials that make use of those visualizations have been developed and are being used in K-12 classrooms in ways that demonstrate the vitality of the geosciences. For example, the Center for Geoscience and Society at the American Geosciences Institute (AGI) helped to develop a publication that outlines an inquiry-based approach to introducing students to the interpretation of scientific visualizations, even when they have had little to no prior experience with such media. To facilitate these uses, the SVS team worked with Center staff and others to adapt the visualizations, primarily by removing most of the labels and annotations. Engaging with these visually compelling resources serves as an invitation for students to ask questions, interpret data, draw conclusions, and make use of other processes that are key components of scientific thought. This presentation will share specific resources for K-12 teaching (all of which are available online, from NASA, and/or from AGI), as well as the instructional principles that they incorporate.

    Internationally the preparation and ongoing education of nurses continues to evolve in response the changing nature of both nursing and health care. The move into third level structures that has taken place in countries such as the UK and the Republic of Ireland, results in new challenges to the historical fabric of nurse education. One such challenge is monitoring of nursing students' attendance. Viewed by students as a patriarchal and draconian measure, the nursing profession historically value their ability to ensure the public and professional bodies that nursing students fully engage with educational programmes. University class sizes and the increased perception of student autonomy can negate against formalised monitoring systems. This paper reports on an evaluation of one such monitoring system. The findings revealed that attendance was recognised implicitly by nurse educators as an important learning activity within these programmes results and that current methods employed were less than reliable and so did little to appropriately control the phenomenon. Subsequent to the evaluation; a standardised approach to the measurement of absenteeism was employed. Deliberate short-term absence was a feature of this group. Reasons cited included travelling long distances, dissatisfaction with programme timetables and personal reasons. Preventative measures employed included improvement in student timetable delivery.

    Smoking is common among health professional students. The aim of this study was to assess the smoking habits of the pharmacy students attending the University of Medicine and Pharmacy in Târgu Mureș (UMPh TM), Romania. Smoking habits and attitudes toward smoking among 414 pharmacy students attending UMPh TM (86% female) were evaluated using a self-completed questionnaire. The rate of smoking increases during the time students attend the university (24.1% to 33.3% from 1st to 5th year) and males are significantly are more likely to smoke than females (41.4% vs. 27.3%, p=0.042). 36.9% of the smoking pharmacy students are tobacco-dependent, and 40.4% of smokers started daily smoking at the age of 16-19. We found significant differences between smoker and non-smoker pharmacy students regarding their attitudes toward smoking and tobacco control policies, with non-smokers being more supportive of smoke-free policies. Prevention programs and education have a very important role in decreasing the percentage of smokers and support for smokefree policies, but it is critical to begin such programs early in their university training.

    2016-02-06

    This project was undertaken to meet the growing need for training personnel who will be involved in professional careers requiring knowledge of radiochemistry, such as those working in radionuclide production, and in biological, industrial, medical and environmental fields that use radionuclides in their work. The goal of the project was to provide financial assistance to students and trainees from academic and government institutions (US preferred) to attend selected radiochemistry-­related symposia at the Pacifichem 2015 meeting held in Honolulu, Hawaii in December 2015. The funding, meant to provide a portion of an awardee’s travel cost, was specifically directed at attendance to the following symposia: #363, Isotope production-­ Providing Important Materials for Research and Applications; #215, Chemistry of Molecular Imaging, and #11, Chemistry for Development of Theranostic Radiopharmaceuticals. Those symposia were held December 16th (am & pm: #11, #363), December 17th (am: #11, #363; pm: #275) and December 18th (am & pm: #275). Pacifichem meetings are held every 5 years in Honolulu, Hawaii. The meetings are joint sponsored by a number of Chemistry Societies from Pacific Rim countries. The meetings are composed of a large number of symposia (>300) on a wide variety of topics, which make them similar to small meetings within the larger overall meeting. Therefore, attendance at the three symposia within Pacifichem 2015 was similar to attending a meeting focused entirely on radiochemistry-­related topics. To obtain the financial assistance, the student/trainee: (a) had to be an undergraduate student, graduate student or Postdoctoral Fellow in a physical science department or National Laboratory; (b) had to submit a letter from their supervisor indicating that he/she will be enrolled as a student/trainee at the time of the meeting, and were committed to attending the meeting; and (c) had to submit a resume or curriculum vitae along with a brief statement of

  4. Video Lecture Capture Technology Helps Students Study without Affecting Attendance in Large Microbiology Lecture Courses

    Full Text Available Recording lectures using video lecture capture software and making them available for students to watch anytime, from anywhere, has become a common practice in many universities across many disciplines. The software has become increasingly easy to use and is commonly provided and maintained by higher education institutions. Several studies have reported that students use lecture capture to enhance their learning and study for assessments, as well as to catch up on material they miss when they cannot attend class due to extenuating circumstances. Furthermore, students with disabilities and students from non-English Speaking Backgrounds (NESB may benefit from being able to watch the video lecture captures at their own pace. Yet, the effect of this technology on class attendance remains a controversial topic and largely unexplored in undergraduate microbiology education. Here, we show that when video lecture captures were available in our large enrollment general microbiology courses, attendance did not decrease. In fact, the majority of students reported that having the videos available did not encourage them to skip class, but rather they used them as a study tool. When we surveyed NESB students and nontraditional students about their attitudes toward this technology, they found it helpful for their learning and for keeping up with the material.

    2016-03-01

    Exposing K-12 students to cutting edge science that impacts their daily lives can bring classroom lessons to life. Citizen-science projects are an excellent way to bring high-level science to the classroom and help satisfy one of the cornerstone concepts of the Next Generation Science Standards (NGSS), "engaging in practices that scientists and engineers actually use." This can be a daunting task for teachers who may lack the background or resources to integrate these projects into the classroom. This is where scientific societies such as the American Society for Microbiology (ASM) can play a critical role. ASM encourages its members to engage with the K-12 community by providing networking opportunities and resources for ASM members and K-12 teachers to work together to bring microbiology into the classroom.

    2003-12-01

    The K-12 science teacher is always seeking ways of improving and updating their curriculum by integrating the latest research into their most effective classroom activities. However, the daily demands of delivering instruction to large numbers of students coupled with the rapid advances in some fields of science can often overwhelm this effort. The NSF-sponsored Cataclysms and Catastrophes curriculum, developed by scientists from the The University of Texas at Austin Institute for Geophysics (UTIG) and Bureau of Economic Geology (BEG), middle and high school teachers, and UT graduate students (NSF GK-12 fellows) working together through the GK-12 program, is a textbook example of how universities can facilitate this quest, benefiting education at both K-12 and university levels. In 1992, "The Great K-T Extinction Debate" was developed as an activity in the Planet Earth class at the Liberal Arts and Science Academy of Austin as an interdisciplinary approach to science. Taking advantage of the media attention generated by the impact scenario for the K-T extinction, the activity consists of students participating in a simulated senate hearing on the potential causes of the K-T extinction and their implications for society today. This activity not only exposes students to the wide range of science involved in understanding mass extinctions, but also to the social, political and economic implications when this science is brought into the public arena and the corresponding use of data in decision making and disaster preparedness. While "The Great K-T Extinction Debate" was always a popular and effective activity with students, it was in desperate need of updating to keep pace with the evolving scientific debate over the cause of the K-T extinction and the growing body of impact evidence discovered over the past decade. By adding two inquiry-based learning activities that use real geophysical data collected by scientists studying the buried Chicxulub feature as a

    Mayberry, G. C.; Mattietti, G. K.

    2017-12-01

    The Washington DC area has interesting geology and a multitude of agencies that deal with the geosciences, yet K-12 public school students in DC, most of whom are minorities, have limited exposure to the geosciences. Geoscience agencies in the DC area have a unique opportunity to address this by introducing the geosciences to local students who otherwise may not have such an opportunity, by highlighting the geology in the students' "backyard," and by leveraging partnerships among DC-based geoscience-related agencies. The USGS and George Mason University are developing a project called DC Rocks, which will give DC's students an exciting introduction into the world of geoscience with place-based learning opportunities that will make geoscience relevant to their lives and their futures. Both the need in DC and the potential for lasting impact are great; the geosciences have the lowest racial diversity of all the science, technology, engineering, and math (STEM) fields, 89% of students in DC public schools are minorities, and there is no dedicated geoscience curriculum in DC. DC Rocks aims to give these students early exposure to the earth sciences, and encourage them to consider careers in the profession. DC Rocks will work with partner agencies to apply several methods that are recommended by researchers to increase the participation of minority students in the geosciences, including providing profoundly positive experiences that spark interest in the geosciences (Levine et al., 2007); increasing students' sense of belonging in the geosciences (Huntoon, et al, 2016); and place-based teaching practices that emphasize the study of local sites (Semken, 2005), such as DC's Rock Creek Park. DC Rocks will apply these methods by coordinating local geoscientists and resources to provide real-world examples of the geosciences' impact on students' lives. Through the DC Rocks website, educators will be able to request geoscience-related resources such as class presentations by

    Chabalengula, Vivien M.; Mumba, Frackson

    2017-11-01

    The current K-12 Science Education framework and Next Generation Science Standards (NGSS) in the United States emphasise the integration of engineering design in science instruction to promote scientific literacy and engineering design skills among students. As such, many engineering education programmes have developed curriculum materials that are being used in K-12 settings. However, little is known about the nature and extent to which engineering design skills outlined in NGSS are addressed in these K-12 engineering education programme curriculum materials. We analysed nine K-12 engineering education programmes for the nature and extent of engineering design skills coverage. Results show that developing possible solutions and actual designing of prototypes were the highly covered engineering design skills; specification of clear goals, criteria, and constraints received medium coverage; defining and identifying an engineering problem; optimising the design solution; and demonstrating how a prototype works, and making iterations to improve designs were lowly covered. These trends were similar across grade levels and across discipline-specific curriculum materials. These results have implications on engineering design-integrated science teaching and learning in K-12 settings.

    Umaru Mustapha Zubairu

    2016-11-01

    Full Text Available For over a century, scholars have argued that religious education is crucial for the developed of students' moral competencies. This study sought to empirically test this assertion by comparing the moral competencies of two sets of Muslim accounting students: those who had attended a religious secondary school and those who attended a public (secular secondary school in Malaysia. The focus on accounting students is quite important in an era where the moral competencies of accountants has been in the public eye due to their complicity in the rash of financial scandals that have plagued the business world over the last two decades. The Muslim Accountant Moral Competency Test (MAMOC was developed by a collaboration with Islamic accounting scholars and was used to measure the students' moral competencies. Although the results revealed that there was no difference in the moral competencies of both sets of students, they both displayed satisfactory levels of moral competency which vindicates the Malaysian government's policy of mandating Islamic education in all secondary schools, whether religious or secular.

    Full Text Available This study investigated the relations between parents and various school staff involvement, and student attendance across time from the viewpoint of school staff in Japan. In addition, student attendance characteristics were classified to investigate potential differences among students related to time and involvement of parents and staff. The research participants were Japanese elementary, junior, and senior high school staff (N = 206 who consented to participate in the survey. All participants were sampled from various areas of Japan and recruited through a web-based survey. Data were collected by the polling organization Internet Research Service MELLINKS (Tokyo, Japan, through their web panel (see www.mellinks.co.jp. The results indicated that during the early period of support, there was no positive correlation between class teachers’ involvement and students’ attendance. However, during the late period of support, it had a positive correlation. Surprisingly, the school nurses’ involvement was critical even in the early periods. Furthermore, in the late period, the results of ANOVAs assessing difference among the student attendance categories showed that maintaining and recovery types had higher scores of parents’ and class teachers’ involvement than non-maintaining and declining types. This study suggests that flexibility of collaboration among parents and various school staff across time is an important component to support student attendance.

    2011-04-01

    Full Text Available Abstract Background Cervical cancer incidence and mortality may be reduced by organized screening. Participant compliance with the attendance recommendations of the screening program is necessary to achieve this. Knowledge about the predictors of compliance is needed in order to enhance screening attendance. Methods The Norwegian Co-ordinated Cervical Cancer Screening Program (NCCSP registers all cervix cytology diagnoses in Norway and individually reminds women who have no registered smear for the past three years to make an appointment for screening. In the present study, a questionnaire on lifestyle and health was administered to a random sample of Norwegian women. The response rate was 68%. To address the predictors of screening attendance for the 12,058 women aged 25-45 who were eligible for this study, individual questionnaire data was linked to the cytology registry of the NCCSP. We distinguished between non-attendees, opportunistic attendees and reminded attendees to screening for a period of four years. Predictors of non-attendance versus attendance and reminded versus opportunistic attendance were established by multivariate logistic regression. Results Women who attended screening were more likely than non-attendees to report that they were aware of the recommended screening interval, a history of sexually transmitted infections and a history of hormonal contraceptive and condom use. Attendance was also positively associated with being married/cohabiting, being a non-smoker and giving birth. Women who attended after being reminded were more likely than opportunistic attendees to be aware of cervical cancer and the recommended screening interval, but less likely to report a history of sexually transmitted infections and hormonal contraceptive use. Moreover, the likelihood of reminded attendance increased with age. Educational level did not significantly affect the women's attendance status in the fully adjusted models. Conclusions The

    Incorporating K-12 students in scientific research processes and opportunities in their communities is a great way to bridge the gap between research and education and to start building science research capacity at an early age. One goal of the Experimental Program to Stimulate Competitive Research (EPSCoR) Alaska Adapting to Changing Environments project is to engage the local community in the research as well as to share results with the people. By giving K-12 students Global Positioning System (GPS) units, and allowing them to collect and map their own data, they are being exposed to some of the research methods being used by scientists in the Alaska ACE project. This hands-on, minds-on method has been successfully used in formal education settings such as a Junior High School classroom in Nuiqsut, Alaska as well as in informal education settings such as summer camps in Barrow, Alaska and Kenai, Alaska. The students progress from mapping by hand to collecting location data with their GPS units and cameras, and imputing this information into ArcGIS Online to create map products. The data collected were from sites ranging from important places in the community to sites visited during summer camps, with students reflecting on data and site significance. Collecting data, using technology, and creating map products contribute to science skills and practices students need to conduct research of their own and to understand research being done around them. The goal of this education outreach implementation is to bring students closer to the research, understand the process of science, and have the students continue to collect data and contribute to research in their communities. Support provided for this work from the Alaska EPSCoR NSF Award #OIA-1208927 and the state of Alaska is gratefully acknowledged.

    Sund, Kristian J.; Bignoux, Stephane

    In this study we attempt to answer Romer’s (1993) question: “Should attendance be mandatory?” Contrary to many existing studies, we conclude that in the case of business and management programs the answer is ‘no’. In a study of over 900 undergraduate strategy students, spanning four academic years......, we examine the link between attendance and exam results. Unlike prior research on this topic, our findings show that attendance is not the best determinant of student performance. We find instead that the best determinant of student performance for third year bachelor students is their over......-all degree classification, which we see as a proxy for academic ability. We suggest that attendance may simply be a reflection of student conscientiousness, engagement and motivation. We also challenge the assumptions about gender differences found in prior research on student attendance and student...

    To determine whether fitness-center attendance established with the provision of weekly monetary incentives persisted after the discontinuation, or decreased frequency, of incentives. One hundred seventeen first-year college students participated during the 2011-2012 academic year. A randomized controlled trial with control, discontinued-incentive, and continued-incentive conditions was conducted. During fall semester, students in incentive conditions received weekly monetary payments for meeting fitness-center attendance goals. During spring semester, discontinued-incentive condition participants no longer received incentives, whereas continued-incentive condition participants received payments on a variable-interval schedule. ID-card attendance records tracked fitness-center attendance. Goal completion decreased from 63% in the incentive groups during the fall semester to 3% in the discontinued-incentive condition, and 39% in the continued-incentive condition during the spring semester. There was not a significant interaction between condition and body mass index change, F(6, 332) = 0.67, p = .68. Incentive discontinuation resulted in students no longer meeting fitness-center attendance goals. A variable-interval reward schedule better maintained attendance.

    Chavajay, Pablo; Skowronek, Jeffrey

    2008-12-01

    Acculturation stress reported by 130 international students attending a university in Utah for about 2 yr. was examined. On the Acculturative Stress Scale for International Students, few students reported experiencing acculturation stress, but responses to four open-ended questions indicated many students perceived experience of acculturation stresses related to discrimination, feelings of loneliness, and academic concerns. The contrast of findings for the scale scores and the open-ended questions indicate the complexity of assessing international students' acculturation experiences of living and studying in the USA and suggest the usefulness of complementary methodologies for assessing such experience.

    2008-12-01

    Many science and research skills are taught by osmosis in graduate programs with the expectation that students will develop good communication skills (speaking, writing, and networking) by observing others, attending meetings, and self reflection. A new National Science Foundation Graduate Teaching Fellows in K- 12 Education (GK-12; http://ehrweb.aaas.org/gk12new/) program at UCLA (SEE-LA; http://measure.igpp.ucla.edu/GK12-SEE-LA/overview.html ) attempts to make the development of good communication skills an explicit part of the graduate program of science and engineering students. SEE-LA places the graduate fellows in two pairs of middle and high schools within Los Angeles to act as scientists-in- residence. They are partnered with two master science teachers and spend two-days per week in the classroom. They are not student teachers, or teacher aides, but scientists who contribute their content expertise, excitement and experience with research, and new ideas for classroom activities and lessons that incorporate inquiry science. During the one-year fellowship, the graduate students also attend a year-long Preparing Future Faculty seminar that discusses many skills needed as they begin their academic or research careers. Students are also required to include a brief (two-page) summary of their research that their middle or high school students would be able to understand as part of their published thesis. Having students actively thinking about and communicating their science to a pre-college audience provides important science communication training and helps contribute to science education. University and local pre- college school partnerships provide an excellent opportunity to support the development of graduate student communication skills while also contributing significantly to the dissemination of sound science to K-12 teachers and students.

    College students have been the focus of many studies on suicidal ideation with or without suicidal behavior. Little attention has been given to their non-college-attending peers on these issues. We examined the 12-month prevalence and mental health treatment of suicidal ideation with or without suicidal behavior among college students aged 18-25 years and their non-college-attending peers in the United States. We assessed data from 135,300 persons aged 18-25 years who participated in the 2008-2013 National Surveys on Drug Use and Health. Descriptive analyses and multivariate logistic regression models were applied. Compared with full-time college students, high school students, those not enrolled in a school or college, and part-time college students were more likely to attempt suicide with a plan (model-adjusted prevalence = 0.67% vs 1.09%, 1.06%, and 1.07%, respectively). The mental health treatment rate among full-time college students with suicidal ideation with or without suicidal behavior was similar to the rates among the other 3 counterparts. The effects of race/ethnicity and serious mental illness on receipt of mental health treatment were significantly larger among those who did not perceive unmet treatment need than among those who perceived unmet treatment need (P = .019 and P = .001, respectively). Compared to full-time college students, non-college-attending young adults and part-time college students were at higher risk for attempting suicide with a plan. Suicide prevention and intervention strategies should emphasize increasing access to mental health treatment among both college students with suicidal ideation with or without suicidal behavior and their non-college-attending peers (particularly among minorities and those who seem to be at low risk because they are without serious mental illness and report no need for mental health treatment). © Copyright 2016 Physicians Postgraduate Press, Inc.

    Hickman, Paul

    2002-04-01

    It is appropriate that after almost half a century of Science and Mathematics education reform we take a look back and a peek forward to understand the present state of this wonderfully complex system. Each of the components of this system including teaching, professional development, assessment, content and the district K-12 curriculum all need to work together if we hope to provide quality science, mathematics and technology education for ALL students. How do the state and national standards drive the system? How do state policies on student testing and teacher licensure come into play? How do we improve the preparation, retention and job satisfaction of our K-12 teachers? What initiatives have made or are making a difference? What else needs to be done? What can the physics community do to support local efforts? This job is too big for any single organization or individual but we each can contribute to the effort. Our Center at Northeastern University, with support from the National Science Foundation, has a sharply defined focus: to get high quality, research-based instructional materials into the hands of K-12 classroom teachers and provide the support they need to use the materials effectively in their classrooms.

  13. "It's worth our time": a model of culturally and linguistically supportive professional development for K-12 STEM educators

    Science.gov (United States)

    Charity Hudley, Anne H.; Mallinson, Christine

    2017-09-01

    Professional development on issues of language and culture is often separate from professional development on issues related to STEM education, resulting in linguistic and cultural gaps in K-12 STEM pedagogy and practice. To address this issue, we have designed a model of professional development in which we work with educators to build cultural and linguistic competence and to disseminate information about how educators view the relevance of language, communication, and culture to STEM teaching and learning. We describe the design and facilitation of our model of culturally and linguistically responsive professional development, grounded in theories of multicultural education and culturally supportive teaching, through professional development workshops to 60 K-12 STEM educators from schools in Maryland and Virginia that serve African American students. Participants noted that culturally and linguistically responsive approaches had yet to permeate their K-12 STEM settings, which they identified as a critical challenge to effectively teaching and engaging African-American students. Based on pre-surveys, workshops were tailored to participants' stated needs for information on literacy (e.g., disciplinary literacies and discipline-specific jargon), cultural conflict and mismatch (e.g., student-teacher miscommunication), and linguistic bias in student assessment (e.g., test design). Educators shared feedback via post-workshop surveys, and a subset of 28 participants completed in-depth interviews and a focus group. Results indicate the need for further implementation of professional development such as ours that address linguistic and cultural issues, tailored for K-12 STEM educators. Although participants in this study enumerated several challenges to meeting this need, they also identified opportunities for collaborative solutions that draw upon teacher expertise and are integrated with curricula across content areas.

    Irwin, Nigel; Burnett, Kathryn M; McCarron, Paul A

    2018-03-01

    As the higher education (HE) classroom begins to adopt newer internet-based technologies, the relationship between attendance and performance needs to be re-evaluated, particularly for professional degree courses such as pharmacy. In the present study, we aimed to establish if an association exists between attendance at all timetabled classes and academic performance, in a Clinical Pharmacology and Therapeutics (CPT) module, as part of the Master of Pharmacy (MPharm) degree course at Ulster University. Data on attendance, final examination and coursework performance were collected over two academic years (2013-14 and 2014-15) of the CPT module at Ulster. In total 67 students were analysed. The MPharm degree at Ulster University implements an attendance policy, both as a pastoral support tool and to reinforce the need for professional conduct as a pharmacist. Student (2013-14 and 2014-15, n = 35 and 32, respectively) attendance on the module across both year groups was approximately 80%. We observed positive, and statistically significant relationships between attendance and performance on the examination, and especially in the coursework elements of the module. Student failure (below 40%) in the final examination was linked to attendance below an 80% threshold in nine of 12 cases. Reasons for not attending class varied, but illness was unquestionably the most commonly cited extenuation. Taken together, these data confirm a convincing association between student attendance and academic achievement. Our studies promote the use of attendance monitoring policies for professional degree courses such as pharmacy. Copyright © 2017 Elsevier Inc. All rights reserved.

    2014-12-01

    Initiating New Science Partnerships in Rural Education (INSPIRE), a NSF Graduate K-12 (GK-12) program at Mississippi State University, pairs STEM graduate students with local K-12 teachers to bring new inquiry and technology experiences to the classroom (www.gk12.msstate.edu). The graduate fellows prepare lessons for the students incorporating different facets of their research. The lessons vary in degree of difficulty according to the content covered in the classroom and the grade level of the students. The focus of each lesson is directed toward the individual research of the STEM graduate student using inquiry based designed activities. Scientific instruments that are used in STEM research (e.g. SkyMaster weather stations, GPS, portable SEM, Inclinometer, Soil Moisture Probe, Google Earth, ArcGIS Explorer) are also utilized by K-12 students in the activities developed by the graduate students. Creativity and problem solving skills are sparked by curiosity which leads to the discovery of new information. The graduate students work to enhance their ability to effectively communicate their research to members of society through the creation of research linked classroom activities, enabling the 7-12th grade students to connect basic processes used in STEM research with the required state and national science standards. The graduate students become respected role models for the high school students because of their STEM knowledge base and their passion for their research. Sharing enthusiasm for their chosen STEM field, as well as the application techniques to discover new ideas, the graduate students stimulate the interests of the classroom students and model authentic science process skills while highlighting the relevance of STEM research to K-12 student lives. The measurement of the student attitudes about science is gathered from pre and post interest surveys for the past four years. This partnership allows students, teachers, graduate students, and the public to

  19. Nucleoli in human early erythroblasts (K2, K1, K1/2 cells).

    Science.gov (United States)

    Smetana, K; Jirásková, I; Klamová, H

    2005-01-01

    Human early erythroid precursors classified according to the nuclear size were studied to provide information on nucleoli in these cells using simple cytochemical procedures for demonstration of RNA and proteins of silver-stained nucleolar organizers. K2 cells with nuclear diameter larger than 13 microm and K1 cells with nuclear diameter larger than 9 microm corresponding to proerythroblasts and macroblasts (large basophilic erythroblasts) mostly possessed large irregularly shaped nucleoli with multiple fibrillar centres representing "active nucleoli". K1/2 cells with nuclear diameter smaller than 9 microm corresponding to small basophilic erythroblasts were usually characterized by the presence of micronucleoli representing "inactive nucleolar types". On the other hand, a few K1/2 cells contained large nucleoli with multiple fibrillar centres similar to those present in K2 cells and thus appeared as "microproerythroblasts". The nucleolar asynchrony expressed by the presence of large irregularly shaped nucleoli with multiple nucleoli (active nucleoli) and ring-shaped nucleoli (resting nucleoli) in one and the same nucleus of K2 or K1 cells was not exceptional and might reflect a larger resistance of these cells to negative factors influencing the erythropoiesis. The intranucleolar translocation of silver-stained nucleolus organized regions was noted in K2 cells and might indicate the premature aging of these cells without further differentiation. More studies, however, are required in this direction.

  20. Cool Science: K-12 Climate Change Art Displayed on Buses

    Science.gov (United States)

    Chen, R. F.; Lustick, D. S.; Lohmeier, J.; Thompson, S. R.

    2015-12-01

    Cool science is an art contest where K12 students create placards (7" x 22") to educate the public about climate change. Students are prompted to create their artwork in response to questions such as: What is the evidence for climate change? How does climate change impact your local community? What can you do to reduce the impacts of climate change? In each of three years, 500-600 student entrees have been submitted from more than 12 school districts across Massachusetts. A panel of judges including scientists, artists, rapid transit representatives, and educators chooses elementary, middle, and high school winners. Winners (6), runners-up (6), and honorable mentions (12) and their families and teachers are invited to an annual Cool Science Award Ceremony to be recognized and view winning artwork. All winning artwork is posted on the Cool Science website. The winning artwork (2 per grade band) is converted into placards (11" x 28") and posters (2.5' x 12') that are placed on the inside (placards) and outside (posters) of buses. Posters are displayed for one month. So far, Cool Science was implemented in Lowell, MA where over 5000 public viewers see the posters daily on the sides of Lowell Rapid Transit Authority (LRTA) buses, making approximately 1,000,000 impressions per year. Cool Science acts to increase climate literacy in children as well as the public, and as such promotes intergenerational learning. Using art in conjunction with science learning about climate change appears to be effective at engaging not just traditionally high achieving science students, but also those interested in the creative arts. Hearing winners' stories about how they created their artwork and what this contest meant to them supports the idea that Cool Science attracts a wide diversity of students. Parents discuss climate change with their children. Multiple press releases announcing the winners further promotes the awareness of climate change throughout school districts and their

    McCann, Ann L; Lacy, Ernestine S; Miller, Barbara H

    2014-03-01

    A study was conducted at Texas A&M University Baylor College of Dentistry (TAMBCD) in fall 2011 to identify the reasons underrepresented minority (URM) students chose to attend TAMBCD, the factors that supported their success as enrolled students, and their perceptions of the institution's cultural climate. A survey distributed online to all URM students received a 79 percent response rate (129/164). The respondents were primarily Hispanic (62 percent Mexican American and other Hispanic) and African American (33 percent) and had attended a college pipeline program (53 percent). The top reasons these students chose TAMBCD were reputation, location, and automatic acceptance or familiarity from being in a predental program. Alumni had most influenced them to attend. Regarding support services, the largest percentage reported not using any (44 percent); personal advising and tutoring were reported to be the most commonly used. In terms of climate, discrimination was reported by 22 percent (n=29), mostly from classmates and clinical faculty. The majority (87 percent) reported their cultural competence program was "effective" and agreed that faculty (83 percent), staff (85 percent), and students (75 percent) were culturally competent. Overall, the students were "satisfied" with how they were treated (88 percent), their education (91 percent), and the services/resources (92 percent). This information is being used to continue to improve the school's cultural climate and to conduct a broader assessment of all students.

  12. Involving Practicing Scientists in K-12 Science Teacher Professional Development

    Bertram, K. B.

    2011-12-01

    The Science Teacher Education Program (STEP) offered a unique framework for creating professional development courses focused on Arctic research from 2006-2009. Under the STEP framework, science, technology, engineering, and math (STEM) training was delivered by teams of practicing Arctic researchers in partnership with master teachers with 20+ years experience teaching STEM content in K-12 classrooms. Courses based on the framework were offered to educators across Alaska. STEP offered in-person summer-intensive institutes and follow-on audio-conferenced field-test courses during the academic year, supplemented by online scientist mentorship for teachers. During STEP courses, teams of scientists offered in-depth STEM content instruction at the graduate level for teachers of all grade levels. STEP graduate-level training culminated in the translation of information and data learned from Arctic scientists into standard-aligned lessons designed for immediate use in K-12 classrooms. This presentation will focus on research that explored the question: To what degree was scientist involvement beneficial to teacher training and to what degree was STEP scientist involvement beneficial to scientist instructors? Data sources reveal consistently high levels of ongoing (4 year) scientist and teacher participation; high STEM content learning outcomes for teachers; high STEM content learning outcomes for students; high ratings of STEP courses by scientists and teachers; and a discussion of the reasons scientists indicate they benefited from STEP involvement. Analyses of open-ended comments by teachers and scientists support and clarify these findings. A grounded theory approach was used to analyze teacher and scientist qualitative feedback. Comments were coded and patterns analyzed in three databases. The vast majority of teacher open-ended comments indicate that STEP involvement improved K-12 STEM classroom instruction, and the vast majority of scientist open-ended comments

    There is consensus that best clinical practice for dual diagnosis (DD) is integrated mental health and substance use treatment augmented with Alcoholics Anonymous (AA) attendance. This is the first quantitative review of the direction and magnitude of the association between AA attendance and alcohol abstinence for DD patients. A systematic literature search (1993-2017) identified 22 studies yielding 24 effect sizes that met our inclusion criteria (8,075 patients). Inverse-variance weighting of correlation coefficients (r) was used to aggregate sample-level findings and study aims were addressed using random and mixed effect models. Sensitivity and publication bias analyses were conducted to assess the likelihood of bias in the overall estimate of AA-related benefit. AA exposure and abstinence for DD patients were significantly and positively associated (r w =.249; 95% CI.203-.293; Tau=.097). There was also significant heterogeneity in the distribution of effect sizes, (Q(23)=90.714, pAA-related benefit did not differ between 6 (k=7) and 12 (k=12) month follow-up, (Q=.068, pAA benefit was not adversely or substantively impacted by pooling RCT and observational samples (Q=.763, pAA (Q=.023, pAA) is common and, in many cases, DD patients who attend AA will report higher rates of alcohol abstinence relative to DD patients who do not attend AA.

    2016-12-01

    A climate literate citizenry is essential to the long-term success of climate change adaptation and to enhancing resilience of communities to climate change impacts. In support of a National Science Foundation CAREER award, we developed a teacher training workshop on a project that engages students in creating functioning, low-cost weather stations using open source electronics. The workshop aims to improve climate literacy among K-12 students while providing an authentic opportunity to acquire and hone STEM skills. Each station measures temperature, humidity, barometric pressure, light level, soil moisture, and precipitation occurrence. Our day-long workshop focuses on three elements: (1) providing context on the scientific importance of climate observation, (2) equipping teachers with technical skills needed to assemble and use a station from provided components, and (3) highlighting relevant educational standards met by the weather station activities. The workshop was attended by twelve 4th-9th grade teachers from southwest Idaho, all of whom teach at rural and/or Title I schools. Attendees reported having minimal or no previous experience with open source electronics, but all were able to effectively use their weather station with less than two hours of hands-on training. In written and oral post-workshop reflections teachers expressed a strong desire to integrate these activities into classrooms, but also revealed barriers associated with rigid curricular constraints and risk-averse administrators. Continued evolution of the workshop will focus on: (1) extending the duration and exploratory depth of the workshop, (2) refining pre- and post-assessments and performing longitudinal monitoring of teacher participants to measure short- and long-term efficacy of the workshop, and (3) partnering with colleagues to engage school district administrators in dialog on how to integrate authentic activities like this one into K-12 curriculum.

    Despite the value of 12-step meetings, few studies have examined factors associated with attendance among those living with HIV/AIDS, such as the impact of HIV disease severity and demographics. This study examines predisposing characteristics, enabling resources and need on attendance at Alcoholic Anonymous (AA) and Narcotics Anonymous (NA) meetings among those living with HIV/AIDS and alcohol problems. Secondary analysis of prospective data from the HIV-Longitudinal Interrelationships of Viruses and Ethanol study, a cohort of 400 adults living with HIV/AIDS and alcohol problems. Factors associated with AA/NA attendance were identified using the Anderson model for vulnerable populations. Generalized estimating equation logistic regression models were fit to identify factors associated with self-reported AA/NA attendance. At study entry, subjects were 75% male, 12% met diagnostic criteria for alcohol dependence, 43% had drug dependence and 56% reported attending one or more AA/NA meetings (past 6 months). In the adjusted model, female gender negatively associated with attendance, as were social support systems that use alcohol and/or drugs, while presence of HCV antibody, drug dependence diagnosis, and homelessness associated with higher odds of attendance. Non-substance abuse related barriers to AA/NA group attendance exist for those living with HIV/AIDS, including females and social support systems that use alcohol and/or drugs. Positive associations of homelessness, HCV infection and current drug dependence were identified. These findings provide implications for policy makers and treatment professionals who wish to encourage attendance at 12-step meetings for those living with HIV/AIDS and alcohol or other substance use problems.

    Cutler, Christopher W; Parise, Mary; Seminario, Ana Lucia; Mendez, Maria Jose Cervantes; Piskorowski, Wilhelm; Silva, Renato

    2016-12-01

    This Point/Counterpoint discusses the long-argued debate over whether lecture attendance in dental school at the predoctoral level should be required. Current educational practice relies heavily on the delivery of content in a traditional lecture style. Viewpoint 1 asserts that attendance should be required for many reasons, including the positive impact that direct contact of students with faculty members and with each other has on learning outcomes. In lectures, students can more easily focus on subject matter that is often difficult to understand. A counter viewpoint argues that required attendance is not necessary and that student engagement is more important than physical classroom attendance. This viewpoint notes that recent technologies support active learning strategies that better engage student participation, fostering independent learning that is not supported in the traditional large lecture classroom and argues that dental education requires assimilation of complex concepts and applying them to patient care, which passing a test does not ensure. The two positions agree that attendance does not guarantee learning and that, with the surge of information technologies, it is more important than ever to teach students how to learn. At this time, research does not show conclusively if attendance in any type of setting equals improved learning or ability to apply knowledge.

    Full Text Available Abstract Background This prospective study investigated the association between life-long methamphetamine and other drug use and high school non-attendance, in a sample of high school students in Cape Town, South Africa. Methods A random sample of 1535 high school students completed a baseline questionnaire in 2006, and were asked to complete a follow-up questionnaire 12 months later. The questionnaire included questions on substance use, including tobacco, alcohol, methamphetamine and cannabis use, demographic factors, and questions relating to school attendance and performance. Results Forty-three percent of the students surveyed at baseline did not complete a follow-up questionnaire after 12 months. Compared with students who were not using selected substances, an adjusted logistic regression model showed that life-time methamphetamine use in addition to other substances was significantly associated with non-attendance (OR = 2.58, 95% CI: 1.24 - 5.36 when other non-substance use factors (repeating a year at school and being older than the norm for current grade were taken into account. Conclusions Early identification of students with methamphetamine and other substance use problems, and a supportive rather than punitive school policy, may be valuable in improving high school completion and student retention rates.

    2014-04-01

    This study explored causal relationships between post-treatment 12-step attendance and abstinence at multiple data waves and examined indirect paths leading from treatment initiation to abstinence 9-years later. Adults (N = 1945) seeking help for alcohol or drug use disorders from integrated healthcare organization outpatient treatment programs were followed at 1-, 5-, 7- and 9-years. Path modeling with cross-lagged partial regression coefficients was used to test causal relationships. Cross-lagged paths indicated greater 12-step attendance during years 1 and 5 and were casually related to past-30-day abstinence at years 5 and 7 respectfully, suggesting 12-step attendance leads to abstinence (but not vice versa) well into the post-treatment period. Some gender differences were found in these relationships. Three significant time-lagged, indirect paths emerged linking treatment duration to year-9 abstinence. Conclusions are discussed in the context of other studies using longitudinal designs. For outpatient clients, results reinforce the value of lengthier treatment duration and 12-step attendance in year 1. Copyright © 2014 Elsevier Inc. All rights reserved.

    2017-06-01

    Full Text Available 1–3 year students attending medical and preventive faculty of a medical university were our research object. Our research had many stages, and at the first one our goal was to examine and to assess basic behavioral risks for reproductive health of students attending medical and preventive faculty of a medical university. We conducted a sociological examination via questioning. 428 students were questioned as per materials collecting program which included 74 parameters; they accounted for 91.6 % out of the overall official number of students, 45.0 % male students and 40.0 % female students combined work and studies. We detected that, as per questioning results, the specific weight of students who took care of their health amounted to 79.2 % boys and 95.2 % girls. However, the students tended to have bad habits, i.e. constant alcohol intake or smoking. And although information on diseases prevention and on how to pursue healthy lifestyle was perfectly available to them, students didn't try to use it and preserve their health. All the respondents said they were against abortion. Girls were likely to adopt a complex approach when choosing a contraceptive, they resorted to hormonal agents, and, with their partners' consent, to condoms. But they often took hormonal agents without any consultations with a gynecologist or an endocrinologist. Contraceptives were rather rarely applied, and students appeared to have no knowledge on risk factors causing reproductive health deterioration. They also tended to be negligent and too self-confident when it came to reproductive health protection. A risk of abortions was very high for girls who didn't use contraceptives, and also all students ran rather high risk of catching sexual diseases. Sexual education is needed to correct contraceptive behavior; medical workers are a main source of information on reproductive health of young people in 7–10 % cases only. We need to create interactive educational programs

    Antenatal care (ANC) is a key strategy to decreasing maternal mortality in low-resource settings. ANC clinics provide resources to improve nutrition and health knowledge and promote preventive health practices. We sought to compare the knowledge, attitude and practices (KAP) among women seeking and not-seeking ANC in rural Kenya. Data from a community-based cross-sectional survey conducted in Western Province, Kenya were used. Nutrition knowledge (NKS), health knowledge (HKS), attitude score (AS), and dietary diversity score (DDS) were constructed indices. χ2 test and Student's t-test were used to compare proportions and means, respectively, to assess the difference in KAP among pregnant women attending and not-attending ANC clinics. Multiple regression analyses were used to assess the impact of the number of ANC visits (none, ANC clinics while 39% had not. The mean (±SD) NKS was 4.6 (1.9) out of 11, HKS was 6.2 (1.7) out of 12, DDS was 4.9 (1.4) out of 12, and AS was 7.4 (2.2) out of 10. Nutrition knowledge, attitudes, and DDS were not significantly different between ANC clinic attending and non-attending women. Among women who attended ANC clinics, 82.6% received malaria and/or antihelmintic treatment, compared to 29.6% of ANC clinic non-attendees. Higher number of ANC clinic visits and higher maternal education level were significantly positively associated with maternal health knowledge. Substantial opportunities exist for antenatal KAP improvement among women in Western Kenya, some of which could occur with greater ANC attendance. Further research is needed to understand multi-level factors that may affect maternal knowledge and practices.

    Full Text Available Objectives. Anxiety disorders are the most common childhood psychiatric disorders. Previous research suggests that South African rates may be high. Our study examined the prevalence and severity of anxiety and depression among Grade 11 and 12 learners attending schools in central Bloemfontein. Learners’ perception of the important stressors as well as the most relevant coping strategies were investigated. Methods. A cross-sectional study was conducted by using self-assessment rating scales and questionnaires. The Hospital Anxiety and Depression Scale (HADS was used to screen for anxiety and depressive symptoms. Participants were provided with an additional list of possible stressors and coping skills, from which they identified those applicable to themselves. All students enrolled in Grades 11 and 12 at the selected schools during August 2009 were eligible for inclusion. Results. Five hundred and fifteen learners participated in the study, of whom 32.0% presented with moderate or severe anxiety and 5.3% with moderate or severe depressive symptoms. Mild symptoms were reported by an additional 29.0% on the anxiety subscale and 14% on the depression subscale of the HADS. Academic workload was reported as the main source of stress (81.4%. Conclusions. Although the study has limitations in terms of methodology and size, resulting in undetermined validity, it indicates possible higher prevalence rates for anxiety and depression than in previous South African studies and worldwide prevalence rates for adolescents. Pupils were generally hesitant to seek help from formal assistance structures provided by the schools, and preferred discussing problems with parents or friends.

  4. The Astronomy and Space Science Concept Inventory: Assessment Instruments Aligned with the K-12 National Science Standards

    Science.gov (United States)

    Sadler, Philip M.

    2011-01-01

    We report on the development of an item test bank and associated instruments based on those K-12 national standards which involve astronomy and space science. Utilizing hundreds of studies in the science education research literature on student misconceptions, we have constructed 211 unique items that measure the degree to which students abandon such ideas for accepted scientific views. Piloted nationally with 7599 students and their 88 teachers spanning grades 5-12, the items reveal a range of interesting results, particularly student difficulties in mastering the NRC Standards and AAAS Benchmarks. Teachers generally perform well on items covering the standards of the grade level at which they teach, exhibiting few misconceptions of their own. Teachers dramatically overestimate their students’ performance, perhaps because they are unaware of their students’ misconceptions. Examples are given showing how the developed instruments can be used to assess the effectiveness of instruction and to evaluate the impact of professional development activities for teachers.

  5. Career education attitudes and practices of K-12 science educators

    Science.gov (United States)

    Smith, Walter S.

    A random sample of 400 K-12 science educators who were members of the National Science Teachers Association were surveyed regarding their attitude toward and practice of career education in their science teaching. These science teachers rejected a narrowly vocational view, favoring instead a conception of career education which included self-perception, values analysis, and vocational skills objectives. The science educators affirmed the importance of career education for a student's education, asserted career education ought to be taught in their existing science courses, and expressed a willingness to do so. Fewer than one-third of the science teachers, however, reported incorporating career education at least on a weekly basis in their science lessons. The major impediment to including more career education in science teaching was seen to be their lack of knowledge of methods and materials relevant to science career education, rather than objections from students, parents, or administrators; their unwillingness; or their evaluation of career education as unimportant. Thus, in order to improve this aspect of science teaching, science teachers need more concrete information about science career education applications.

  9. Rural/Nonrural Differences in College Attendance Patterns.

    Science.gov (United States)

    Byun, Soo-Yong; Irvin, Matthew J; Meece, Judith L

    Using data from the National Education Longitudinal Study of 1988, this study documented college attendance patterns of rural youth in terms of the selectivity of first postsecondary institution of attendance, the timing of transition to postsecondary education, and the continuity of enrollment. The study also examined how these college attendance patterns among rural students differed from those among their non-rural counterparts and which factors explained these rural/nonrural differences. Results showed that rural youth were less likely than their nonrural counterparts to attend a selective institution. In addition, rural youth were more likely to delay entry to postsecondary education, compared to their urban counterparts. Finally, rural students were less likely than their urban counterparts to be continuously enrolled in college. Much of these rural/nonrural disparities in college attendance patterns were explained by rural/nonrural differences in socioeconomic status and high school preparation. Policy implications, limitations of the study, and future research directions are also discussed.

Since Thursday 1 November, the P42 beam line of the SPS has once again been sending protons to the beryllium target to produce the K12 kaon beam line eagerly awaited by the NA62 collaboration. This was no trivial matter! The first step was to clear the decks by dismantling the entire H10 beam line and NA60 experiment, as well as most of the NA48 experiment - representing some 1000 tonnes of equipment in total! Next came the complete renovation of the infrastructure, which dated back to 1979. The operation called on the expertise of virtually all branches of the EN and GS departments, as well as the Radiation Protection group: from ...

    The Classroom Performance System (CPS) is an instructional technology tool that increases student performance and addresses different learning styles. Instructional technologies are used to promote active learning; however, student embarrassment issue in a multicultural setting is not addressed. This study assessed the effect of the CPS on student participation, attendance, and achievement in multicultural college-level anatomy and physiology classes at South Texas College, where the first spoken language is not English. Quantitative method and quasi-experimental design were employed and comparative statistic methods and pre-post tests were used to collect the data. Participants were college students and sections of study were selected by convenient sampling. Participation was 100% during most of the lectures held and participation rate did not strike above 68% in control group. Attendance was significantly higher in CPS sections than the control group as shown by t-tests. Experimental sections had a higher increase in the pre-post test scores and student averages on lecture exams increased at a higher rate as compared to the control group. Therefore, the CPS increased student participation, attendance, and achievement in multicultural anatomy and physiology classes. The CPS can be studied in other settings where the first spoken language is English or in other programs, such as special education programs. Additionally, other variables can be studied and other methodologies can be employed.

    2017-11-01

    In the department of engineering, students are required to fulfil at least 80 percent of class attendance. Conventional method requires student to sign his/her initial on the attendance sheet. However, this method is prone to cheating by having another student signing for their fellow classmate that is absent. We develop our hypothesis according to a verse in the Holy Qur’an (95:4), “We have created men in the best of mould”. Based on the verse, we believe each psychological characteristic of human being is unique and thus, their speech characteristic should be unique. In this paper we present the development of speech biometric-based attendance system. The system requires user’s voice to be installed in the system as trained data and it is saved in the system for registration of the user. The following voice of the user will be the test data in order to verify with the trained data stored in the system. The system uses PSD (Power Spectral Density) and Transition Parameter as the method for feature extraction of the voices. Euclidean and Mahalanobis distances are used in order to verified the user’s voice. For this research, ten subjects of five females and five males were chosen to be tested for the performance of the system. The system performance in term of recognition rate is found to be 60% correct identification of individuals.

    2015-01-01

    Self-help groups are beneficial for many people with addiction, predominantly through 12-step models. Yet obstacles to attendance also occur. We explored attendance patterns and attitudes toward self-help groups by 165 outpatient females with co-occurring posttraumatic stress disorder (PTSD) and substance use disorder (SUD), the first study of its kind. Cross-sectional self-report data compared adults versus adolescents, and those currently attending self-help versus not attending. We also explored attendance in relation to perceptions of the PTSD/SUD relationship and symptom severity. Adults reported higher attendance at self-help than adolescents, both lifetime and currently. Among current attendees, adults also attended more weekly groups than adolescents. Yet only a minority of both age cohorts attended any self-help in the past week. Adults perceived a stronger relationship between PTSD and SUD than adolescents, but both age groups gave low ratings to the fact that self-help groups do not address PTSD. That item also had low ratings by both those currently attending and not attending self-help. Analysis of those not currently attending identified additional negative attitudes toward self-help (spirituality, addiction as a life-long illness, sayings, and the fellowship). Symptom severity was not associated with attendance, but may reflect a floor effect. Finally, a surprising finding was that all-female groups were not preferred by any subsample. Conclusions/Importance. Creative solutions are needed to address obstacles to self-help among this population. Addressing trauma and PTSD, not just SUD, was valued by females we surveyed, and may be more helpful than all-female groups per se.

    Contests can engage, motivate, instruct and inspire students of all grade levels and interests. What are the ingredients necessary for a successful science contest? The Institute for Global Environmental Strategies (IGES) has recommendations for designing science-based competitions that are both fun and educational for for elementary and secondary students. These recommendations were developed as a result of IGES' experience gained through two annual student competitions that focus on Earth science topics: An annual art contest, for grades 2-4, challenges U.S. students to explore a specific Earth science topic. For example, past themes have included Polar Explorations: Going to Extremes (2006); Connect-4: Air, Land, Water, and Life (2005); and Picture Me: What Kind of Earth Explorer Would I Be? (2004). The contest supports national science education standards for grades K-4, and includes suggested classroom activities, books, and movies. The Thacher Scholarship was founded in 2000 by IGES in honor of the late Peter S. Thacher, a former IGES board member and leader in promoting the use of satellite remote sensing. The $4,000 scholarship is awarded to exceptional high school students displaying the best use of satellite remote sensing in understanding our changing planet.

    The lack of diversity in physics is a known problem, and yet efforts to change our demographics have only had minor effects during the last decade. I will explain some of the hidden barriers that dissuade underrepresented minorities in becoming physicists using a framework borrowed from sociology, Maslow's hierarchy of needs. I will draw from current research at the undergraduate to faculty levels over a variety of STEM fields that are also addressing a lack of diversity. I will also provide analysis from the Joint Institute for Nuclear Astrophysics Center for the Evolution of Elements (JINA-CEE) outreach programs to understand the likelihood of current K-12 students in becoming physicists. Specifically, I will present results from the pre-surveys from our Art 2 Science Camps (ages 8-14) about their attitudes towards science as well as results from analysis of teacher recommendations for our high school summer program. I will conclude with a positive outlook describing the pipeline created by JINA-CEE to retain students from middle school through college. This work was supported in part by the National Science Foundation under Grant No. PHY-1430152 (JINA Center for the Evolution of the Elements).

    The Falcon Telescope Network (FTN) is a global network of small aperture telescopes developed by the Center for Space Situational Awareness Research in the Department of Physics at the United States Air Force Academy (USAFA). Consisting of commercially available equipment, the FTN is a collaborative effort between USAFA and other educational institutions ranging from two- and four-year colleges to major research universities. USAFA provides the equipment (e.g. telescope, mount, camera, filter wheel, dome, weather station, computers and storage devices) while the educational partners provide the building and infrastructure to support an observatory. The user base includes USAFA along with K-12 and higher education faculty and students. The diversity of the users implies a wide variety of observing interests, and thus the FTN collects images on diverse objects, including satellites, galactic and extragalactic objects, and objects popular for education and public outreach. The raw imagery, all in the public domain, will be accessible to FTN partners and will be archived at USAFA. USAFA cadets use the FTN to continue a tradition of satellite characterization and astronomical research; this tradition is the model used for designing the network to serve undergraduate research needs. Additionally, cadets have led the development of the FTN by investigating observation priority schemes and conducting a 'day-in-the-life' study of the FTN in regards to satellite observations. With respect to K-12 outreach, cadets have provided feedback to K-12 students and teachers through evaluation of first-light proposals. In this paper, we present the current status of the network and results from student participation in the project.

    2013-12-01

    Phenology is defined as periodic [or annual] life cycles of plants and animals driven by seasonal environmental changes. Climate change impinges a strong effect on phenology, potentially altering the structure and functioning of ecosystems. In the fall of 2011, the Ashburnham-Westminster Regional School District became the first of five schools to join Harvard University's Phenocam Network with the installation of a webcam to monitor phenology (or 'phenocam') at Overlook Middle School in Ashburnham, Massachusetts. Our school district is now part of a network of near-surface remote sensing phenocams that capture and send images of forest, shrub, and grassland vegetation cover at more than 130 diverse sites in North America. Our phenocam provides a digital image every half hour of the mixed forest canopy north from the school, enabling the detection of changes in canopy development, quantified as canopy 'greenness'. As a part of the Phenocam project, students at the K-12 level have expanded the scope of phenological monitoring protocol that is part of the Harvard Forest Schoolyard Ecology Program, Buds, Leaves, and Global Warming. In this protocol, students work with ecologists at Harvard Forest to monitor buds and leaves on schoolyard trees to determine the length of the growing season, giving them the opportunity to be a part of real and important research concerning the critical environmental issue of climate change. Students involved in the Buds, Leaves, and Global Warming study have the opportunity to compare their ground data on budburst, color change, and leaf drop to the phenocam images, as well as to similar forested sites in locations throughout the United States. Lessons have been developed for comparing student data to phenocam images, canopy greenness time series graphs extracted from the images, and satellite data. Lessons addressing map scale and the Urban Heat Island effect will also be available for teachers. This project will greatly enhance the

    2002-11-01

    This study examines attendance and alcohol use at parties and bars among college students by gender, residence, year in school and legal drinking age. The study participants were respondents in the 1997 and 1999 Harvard School of Public Health College Alcohol Study (CAS). The combined sample consisted of 12,830 students (61% women) who reported use of alcohol in the past 30 days prior to interview. Their responses provided information on attendance and alcohol use at parties (dormitory, fraternity, off campus) and off-campus bars. Logistic regression analyses examined the influence of gender, residence, year in school and legal drinking age related to attendance, drinking/non-drinking and heavy drinking (5 or more drinks) at each select setting. Consistent with the literature, fraternity/ sorority parties were occasions of heavy drinking (49%) among drinkers in those settings, yet they drew upon smaller proportions of students (36%) when compared to off-campus parties (75%) and off-campus bars (68%). Off-campus parties (45%) and bars (37%) were also occasions for heavy drinking among drinkers in these settings. College residence was shown to relate to differential exposure to drinking settings, but residence had less impact on the decision to drink and the level of heavy drinking. Attendance at parties decreased with advance in school years, but attendance at off-campus bars increased. Although heavy drinking at off-campus bars decreased with advancing grade year in school, slightly higher proportions of under-age students (41%) compared to students of legal drinking age (35%) exhibited heavy drinking at off-campus bars. The identification of high-risk settings and their correlates serves to better understand the development of heavy drinking on college campuses. Off-campus parties, as compared to campus parties and bars, may pose greater difficulties related to successful intervention.

    2018-01-01

    Background We estimated the burden of outpatient influenza and cases prevented by vaccination during the 2011/12 and 2012/13 influenza seasons using data from the United States Influenza Vaccine Effectiveness (US Flu VE) Network. Methods We defined source populations of persons who could seek care for acute respiratory illness (ARI) at each of the five US Flu VE Network sites. We identified all members of the source population who were tested for influenza during US Flu VE influenza surveillance. Each influenza-positive subject received a sampling weight based on the proportion of source population members who were tested for influenza, stratified by site, age, and other factors. We used the sampling weights to estimate the cumulative incidence of medically attended influenza in the source populations. We estimated cases averted by vaccination using estimates of cumulative incidence, vaccine coverage, and vaccine effectiveness. Results Cumulative incidence of medically attended influenza ranged from 0.8% to 2.8% across sites during 2011/12 and from 2.6% to 6.5% during the 2012/13 season. Stratified by age, incidence ranged from 1.2% among adults 50 years of age and older in 2011/12 to 10.9% among children 6 months to 8 years of age in 2012/13. Cases averted by vaccination ranged from 4 to 41 per 1,000 vaccinees, depending on the study site and year. Conclusions The incidence of medically attended influenza varies greatly by year and even by geographic region within the same year. The number of cases averted by vaccination varies greatly based on overall incidence and on vaccine coverage. PMID:26271827

    2010-12-01

    The National Academy of Sciences has created a committee of 18 National Academy of Science and Engineering members, academic scientists, cognitive and learning scientists, and educators, educational policymakers and researchers to develop a framework to guide new K-12 science education standards. The committee began its work in January, 2010, released a draft of the framework in July, 2010, and intends to have the final framework in the first quarter of 2011. The committee was helped in early phases of the work by consultant design teams. The framework is designed to help realize a vision for science and engineering education in which all students actively engage in science and engineering practices in order to deepen their understanding of core ideas in science over multiple years of school. These three dimensions - core disciplinary ideas, science and engineering practices, and cross-cutting elements - must blend together to build an exciting, relevant, and forward looking science education. The framework will be used as a base for development of next generation K-12 science education standards.

  13. Systematic study of K+ and K- charge exchange at 8.36 and 12.8 GeV/c

    International Nuclear Information System (INIS)

    Gilchriese, M.G.D.

    1977-08-01

    The results of a wire chamber spectrometer experiment at the Stanford Linear Accelerator Center to study kaon charge exchange reactions are reported. The salient experimental features include good relative normalization between the K + and K - charge exchange reactions and a large increase, with respect to previous experiments, in the number of events obtained for K + n charge exchange at the higher energy. Approximately 1500 events at 12.8 GeV/c and 250 events at 8.36 GeV/c were obtained for each of the reactions K + n → K 0 p, K - p → anti K 0 n, K + p → K 0 Δ 2+ and K - n → anti K 0 Δ - . The results of the experiment show that the K + charge exchange cross sections are larger than the K - cross sections at both energies. In particular it is found that sigma/sub tot/ (K + n → K 0 p)/sigma/sub tot/ (K - p → anti K 0 n) is 1.37 +- 0.22 at 8.36 GeV/c and 1.38 +- 0.09 at 12.8 GeV/c. The ratio of these two reactions is also consistent with no momentum transfer dependence at either beam energy. Similarly it was determined that sigma/sub tot/ (K + p → K 0 Δ 2+ )/sigma/sub tot/ (K - n → anti K 0 Δ - ) is 1.05 +- 0.16 at 8.36 GeV/c and 1.56 +- 0.08 at 12.8 GeV/c. The ratio of these two reactions is also consistent with momentum transfer independence for both beam energies. These results are in clear conflict with the predictions of exchange degenerate Regge pole models

  14. The Community College Effect Revisited: The Importance of Attending to Heterogeneity and Complex Counterfactuals*

    Community colleges are controversial educational institutions, often said to simultaneously expand college opportunities and diminish baccalaureate attainment. We assess the seemingly contradictory functions of community colleges by attending to effect heterogeneity and to alternative counterfactual conditions. Using data on postsecondary outcomes of high school graduates of Chicago Public Schools, we find that enrolling at a community college penalizes more advantaged students who otherwise would have attended four-year colleges, particularly highly selective schools; however, these students represent a relatively small portion of the community college population, and these estimates are almost certainly biased. On the other hand, enrolling at a community college has a modest positive effect on bachelor's degree completion for disadvantaged students who otherwise would not have attended college; these students represent the majority of community college goers. We conclude that discussions among scholars, policymakers, and practitioners should move beyond considering the pros and cons of community college attendance for students in general to attending to the implications of community college attendance for targeted groups of students.

    Full Text Available Background: In recent years, availability of class material including typed lectures, the professor’s Power Point slides, sound recordings, and even videos made a group of students feel that it is unnecessary to attend the classes. These students usually read and memorize typed lectures within two or three days prior to the exams and usually pass the tests even with low attendance rate. Thus, the question is how effective is this learning system and how long the one-night memorized lessons may last.Methods: A group of medical students (62 out of 106 students, with their class attendance and educational achievements in the Medical Mycology and Parasitology course being recorded since two years ago, was selected and their knowledge about this course was tested by multiple choice questions (MCQ designed based on the previous lectures.Results: Although the mean re-exam score of the students at the end of the externship was lower than the corresponding final score, a significant association was found between the scores of the students in these two exams (r=0.48, P=0.01. Moreover, a significant negative association was predicted between the number of absences and re-exam scores (r=-0.26, P=0.037.Conclusion: As our findings show, the phenomenon of recalling the acquired lessons is preserved for a long period of time and it is associated with the students’ attendance. Many factors including generation effect (by taking notes and cued-recall (via slide picture might play a significant role in the better recalling of the learned information in students with good class attendance.Keywords: STUDENT, MEMORY, LONG-TERM, RECALL, ABSENTEEISM, LEARNING

    The collisional excitation transfer for the processes Rb * (5P 3/2 ) + K(4S 1/2 ) → Rb(5S 1/2 ) + K * (4P J ), J = 1/2, 3/2, was investigated using two-photon laser excitation techniques with a thermionic heat-pipe diode as a detector. The population densities of the K 4P J levels induced by collisions with excited Rb atoms as well as those produced by direct laser excitation of the potassium atoms were probed through the measurement of the thermionic signals generated due to the ionization of the potassium atoms emerging from the K(4P J ) → K(7S 1/2 ) excitation channel.

    The National Science Foundation's Graduate Teaching Fellows in K-12 Education (GK-12) Program has enabled science, technology, engineering and mathematics (STEM) graduate schools across the country to become more active in local area K-12 schools. An overview of a graduate student's experiences, insights gained and lessons learned as a Fellow in the 2003-2004 Universidad Metropolitana's (UMET) environmental science and the 2004-2005 University of South Florida's (USF) ocean science GK-12 Programs is presented. The major goals of the 2003-2004 UMET GK-12 Program were 1) to enrich environmental science teaching and learning via a thematic approach in eight local public schools and 2) to provide UMET graduate students with exposure to teaching methodologies and practical teaching experience. Utilizing examples from local environments in and nearby Carolina, Puerto Rico to teach key science principles at Escuela de la Comunidad Juana Rodriguez Mundo provided numerous opportunities to relate science topics to students' daily life experiences. By 2004, the UMET GK-12 Program had successfully engaged the entire student body (primarily comprised of bilingual minority kindergarten to sixth graders), teachers and school administrators in environment-focused teaching and learning activities. Examples of such activities include tree planting projects to minimize local erosion, conducting a science fair for the first time in many years, and numerous opportunities to experience what "real scientists do" while conducting environmental science investigations. During the 2004-2005 academic year, skills, insights and lessons learned as a UMET GK-12 Fellow are being further enhanced through participation in the USF GK-12 OCEANS Program. The overall objectives of the 2004-2005 USF GK-12 OCEANS assignment at Madeira Beach Elementary School in Saint Petersburg, Florida are to 1) engage students from various ethnic backgrounds and cultures in hands-on science activities, 2) enhance the

    Adolescent maturation is associated with delays of the endogenous circadian phase. Consequently, early school schedules may lead to a mismatch between internal and external time, which can be detrimental to adolescent sleep and health. In parallel, chronotype is known to play a role in adolescent health; evening chronotype adolescents are at higher risk for sleep problems and lower academic achievement. In the summer of 2008, Kénogami High School (Saguenay, Canada) was destroyed by fire. Kénogami students were subsequently relocated to Arvida High School (situated 5.3 km away) for the 2008-2009 academic year. A dual school schedule was implemented, with Arvida students attending a morning schedule (0740-1305 h) and Kénogami students an afternoon schedule (1325-1845 h). This study aimed to investigate the effects of such school schedules and chronotype on sleep, light exposure, and daytime functioning. Twenty-four morning and 33 afternoon schedule students wore an actigraph during 7 days to measure sleep and light exposure. Academic achievement was obtained from school. Subjects completed validated questionnaires on daytime sleepiness, psychological distress, social rhythms, school satisfaction, alcohol, and chronotype. Overall, afternoon schedule students had longer sleep duration, lower sleepiness, and lower light exposure than morning schedule students. Evening chronotypes (E-types) reported higher levels of sleepiness than morning chronotypes (M-types) in both morning and afternoon schedules. Furthermore, M-types attending the morning schedule reported higher sleepiness than M-types attending the afternoon schedule. No difference was found between morning and afternoon schedule students with regard to academic achievement, psychological distress, social rhythms, school satisfaction, and alcohol consumption. However, in both schedules, M-type had more regular social rhythms and lower alcohol consumption. In summary, this study emphasizes that an early school

    2011-12-01

    Climate change is a highly interdisciplinary topic, involving not only multiple fields of science, but also social science and the humanities. There are many aspects of climate change science that make it particularly well-suited for exploration in the K-12 setting, including opportunities to explore the unifying processes of science such as complex systems, models, observations, change and evolution. Furthermore, this field of science offers the opportunity to observe the nature of science in action - including how scientists develop and improve their understanding through research and debate. Finally, climate change is inherently highly relevant to students - indeed, students today will need to deal with the consequences of the climate change. The science of climate change is clearly present in current science education standards, both at the National level as well as in the majority of states. Nonetheless, a significant number of teachers across the country report difficulties addressing climate change in the classroom. The National Earth Science Teachers Association has conducted several surveys of Earth and space science educators across the country over the past several years on a number of issues, including their needs and concerns, including their experience of external influences on what they teach. While the number of teachers that report external pressures to not teach climate change science are in the minority (and less than the pressure to not teach evolution and related topics), our results suggest that this pressure against climate change science in the K-12 classroom has grown over the past several years. Some teachers report being threatened by parents, being encouraged by administrators to not teach the subject, and a belief that the "two sides" of climate change should be taught. Survey results indicate that teachers in religious or politically-conservative districts are more likely to report difficulties in teaching about climate change than in

    Full Text Available In this paper, we present how our College of Engineering is developing a growing portfolio of engineering computer games as a parallel learning opportunity for undergraduate engineering and primary (grade K-5 students. Around the world, many schools provide secondary students (grade 6-12 with opportunities to pursue pre-engineering classes. However, by the time students reach this age, many of them have already determined their educational goals and preferred careers. Our College of Engineering is developing resources to provide primary students, still in their educational formative years, with opportunities to learn more about engineering. One of these resources is a library of engineering games targeted to the primary student population. The games are designed by sophomore students in our College of Engineering. During their Introduction to Computational Techniques course, the students use the LabVIEW environment to develop the games. This software provides a wealth of design resources for the novice programmer; using it to develop the games strengthens the undergraduates

    A team of faculty and administrators from The Independent Schools Foundation Academy spend the 2015 - 2016 academic year identifying possible locations in Asia for a year-round outdoor education center. ISF Academy currently has over 1500 students its K-12 bilingual school in Hong Kong, China. The outdoor education center is an extension of the built campus in Pokfulam and will provide students opportunities to live in a natural setting, participate in outdoor educational activities and study in an environment significantly different than a classroom. Currently ISF Academy students in grades 4 - 12 are off campus twice during the academic year in an experiential learning environment. These current programs include camping, hiking, kayaking, other adventurous activities and service learning opportunities. The purpose of the dedicated site is to have a "home base" for ISF Academy and the experiential learning programs. This past year we looked specifically at programs and locations that could also be used by students for ecology and earth systems based research in the senior school (grades 9 - 12). We have looked at sites in Hong Kong, Indonesia, Malaysia and Taiwan. The ideal site will have marine, terrestrial and mangrove ecosystems and allow students to set up long-term research sites in any of these ecosystems. Creating opportunities for authentic research that allows students spend an extended time in a research setting will help them to gain both skills and independence needed in the future at the tertiary level. The evaluation of these sites included identifying potential research partners, site preparation, logistics in and out of the locations, and the heath/safety management of students living and working in a remote location. In parallel to the site evaluations, the curriculum is being developed for the students that is age and skill appropriate using the frame work of the existing guided discovery curriculum in the primary school, and the MYP and DP

    This report contains the detailed description of an experiment which has determined the differential cross section of the K - n→K - n elastic scattering reaction. The results are 12 angular distributions spanning the K - n c.m. energy interval from approximately 1.86 to approximately 2.32 GeV. The measurements have been performed at the CERN PS using a beam of negative kaons with momenta from 1.2 to 2.2 GeV/c incident on a liquid deuterium target. By means of electronic apparatus the process K - d→K - n psub(s) was identified and recorded; this process is basically the same as the K - n elastic reaction insofar as the spectator proton psub(s) has low momentum. The elastic reaction was derived from the above process by taking into account the Fermi motion of the target neutron and by introducing the appropriate corrections to compensate for the effects due to the composite nature of the neutron (double-scattering, final state interaction). These results, constituting the first extensive collection of data on the pure isospin 1 anti KN state have been used in conjunction with other data in a preliminary partial wave analysis of the anti KN elastic system over the c.m. energy range from 1.84 to 2.23 GeV. Mainly for testing purposes, a similar amount of data has been collected for the K - p elastic reaction also from K - d collisions (K - d→K - p nsub(s)). (Auth.)

    In the classroom, the interaction between students, teachers, and datasets is becoming more game like. Software such as GoogleEarth allow students to interact with data on a more personal level; allowing them the dynamically change variables, move arbitrarily, and personalize their experience with the datasets. As this becomes more immersive, traditional software control such as keyboard and mouse begin to hold the student back in terms of intuitive interfacing with the data. This is a problem that has best been tackled by modern gaming systems such as the Wii, XBox 360, and Playstation 3 Systems. By utilizing the solutions given by these gaming systems, it is possible to further a students immersion with a system. Through an NSF ITEST (Information and Technology Experiences for Students and Teachers) grant, researchers at the University of Maine have experimented with using the game controller that is used for interacting with the Nintendo Wii (often called a Wiimote) with existing geodynamic systems in an effort to eases interaction with these systems. Since these game controllers operate using Bluetooth, a common protocol in computing, Wiimotes can easily communicate with existing laptop computers that are issued to Maine students. This paper describes the technical requirements, setup, and usage of Wiimotes as an input device to complex geodynamical systems for use in the K-12 classroom.

    The objective of this study was to ascertain the knowledge of students on the composition of a healthy diet, daily nutritional requirements and the importance of regular exercise. A cross-sectional survey using a self-administered questionnaire with closed and open-ended questions to assess students 'knowledge on diet, nutrition and exercise was conducted. The study group were students of Tswaing High School in Pretoria, South Africa, who were in attendance on a particular day when the study was conducted and who consented to participate in the study Only 500 students of the school participated in the study Results showed that 77% of the students do not have adequate knowledge on diet, nutrition and exercise while 23% of the students showed satisfactory knowledge. Approximately 26% and 16% of the students reported that they participated in rigorous and moderate exercise respectively The study also showed that the majority of the students were however not engaged in physical activities. Students at Tswaing High School do not have adequate knowledge on nutrition, diet and exercise. Their views on what exercise entails were found not to be satisfactory. Programmes/ information or seminars that could assist to inform students on the importance of diet and exercise are therefore suggested.

    2015-12-01

    In previous studies, correlations between attendance and grades in lectures have given variable results and, when statistically significant, the correlation has been weak. In some studies, a sex effect has been reported. Lectures are a teacher-centered learning activity. Therefore, it appeared interesting to evaluate if a stronger correlation between attendance and grades would occur in a face-to-face "evidence-based medicine" course with few lectures and more time dedicated to active learning methods. Small-group work and peer learning were used to foster deep learning and to engage students in their own learning process. Most of the time, students worked in small groups solving contextualized problems and critically analyzing the quality of published medical literature. Peer learning was also developed in collaborative evaluations, and constant feedback was provided. Therefore, it was hypothesized that high attenders would develop a higher self-perception of learning and obtain higher marks than low attenders. Student self-perceptions of their capacity to apply evidence-based medicine were measured by the application of an online self-assessment survey, and objective learning was measured as the grades obtained in a final accumulative individual test. It was found that male students obtained higher grades and were more confident in their achievements than their female peers, despite male and female student attendance being similar. In addition, attendance was correlated with the perceived capacity to apply evidence-based medicine only in male students and was not correlated with academic outcome.

    In 1988, the Education Task Force of the Business Roundtable recommended that American corporations invest in pre-college education. Prior to that date, corporate investment was targeted at higher education. IBM and other corporations responded by encouraging their employees and their corporate philanthropic organizations to develop programs aimed at enhancing pre-college education. The IBM TJ Watson Research Center initiated a Local Education Outreach program, active for these past 23 years, that marshals the resources of our science-rich institution to enhance STEM education in our local schools. We have broad and deep partnerships between the Research Center and local school districts, including New York City. We have just completed our 19th consecutive year of Family Science Saturdays, which brings 4th and 5th grade children, along with their parents, to our Research Center for hands-on workshops in topics like States of Matter, Polymer Science, Kitchen Chemistry, and Sound and Light. The workshops are staffed by IBM volunteers, assisted by local high school student ``Peer Teachers.'' Since 1990, the IBM Corporation has joined with a coalition of other companies, professional engineering societies, and government agencies to sponsor the annual Engineers Week (EWeek) campaign of technical education outreach, serving as Corporate Chair in 1992, 2001, and 2008. In recent years, we have annually recruited around 5000 IBM volunteers to reach out to more than 200,000 K-12 students in order to increase their awareness and appreciation of technical careers and encourage them to continue their studies of STEM (science, technology, engineering, and mathematics). The speaker, who helped found the APS Forum on Education (FED) and served as FED Councillor for 8 years, will review these and other programs for Public and K-12 Technical Education Outreach and Engagement.

    Workforce development strategies to educate, inform, and diversify the veterinary profession of the future must begin with children in elementary school. This article provides a description of the Fat Dogs and Coughing Horses program, which takes a multifaceted approach toward informing young students, beginning in first grade, about the interesting work and career opportunities available in the field of veterinary medicine. The program, a collaboration among Purdue University and Indiana public schools, is supported by a Science Education Partnership Award from the Office of Research Infrastructure Programs, a component of the National Institutes of Health. The overall goal of the program is to provide formal and informal educational opportunities for students, parents, teachers, and the public about the science involved in keeping people and their animals healthy. Examples of health concerns that impact both people and their pets are used to inform and excite children about careers in the health sciences. The program resulted in (1) curricula for students in Grades 1-3, 6, and 9; (2) four children's books and a set of collectible cards which highlight veterinarians, veterinary technicians, and research scientists who work with animals; and (3) four traveling museum-level quality exhibits. Preliminary assessment data has shown that the implementation of the curricula enhanced student science learning and science attitudes and interests. The program provides evidence that partnerships among professionals in veterinary medicine and K-12 education can result in impactful workforce development programs.

    Piloted during the 2011-2012 academic year, the NASA Education Activity Training (NEAT) teacher workshop program has introduced five solar astronomy and space weather activities to over forty Montana K-12 teachers. Because many Montana schools are geographically isolated (40% of Montana students live more than 50 miles from a city) and/or serve traditionally underrepresented groups (primarily Native Americans), professional development for teachers can be costly and time consuming. However, with funding shared by the Atmospheric Imaging Assembly EPO team and the Montana Space Grant Consortium, graduate student specialists are able to host the two-hour NEAT workshops on-site at the schools free of charge, and participating teachers earn two continuing education credits. Leveraging the existing catalogue of research-based NASA activities, the featured NEAT activities were chosen for their ease-of-use and applicability to Montana science standards. These include three advanced activities for older students, such as a paper plate activity for the June 5th, 2012 Transit of Venus, Kinesthetic Astronomy, and the Herschel Infrared experiment, along with two simpler activities for the younger students, such as Solar Cookies and the Electromagnetic War card game. Feedback surveys show that NEAT workshop participants were interested and engaged in the activities and planned on using the activities in their classrooms. With such positive responses, the NEAT program has been a huge success and can serve as a model for other institutions looking to increase their space public outreach and education.

    2016-04-01

    In the 21st century-the century of Information Technology, it is difficult to imagine life without any gadgets: phones, tablets, computers, laptops, and so on. Today, smartphones and tablets are becoming popular, and thus their operating systems become popular too. Android is designed for low-power devices that run on battery power at full capacity, using all of its services, such as cameras, lights, GPS navigation, Wi-Fi, etc. In Kazakhstani universities, the process of checking students’ attendance is one of the important issues, because final grade evaluation of students is based on their total number of appearances and their grades during the whole semester. This raises the question of having some tool to control students’ attendance. There are many possible ways of controlling attendance: there are many examples when universities prefer to control attendance by the use of paper sheet, and some universities prefer to use two-stage way of controlling attendance: firstly, teachers and professors use paper sheet for checking students’ attendance and after this, they fill out these information into a system manually. However, this is not an efficient way since there will be spent much of time for calling students names and putting marks like “presence” or “absence” if the class is a lecture class, and in this class at least 5 groups are presented. Furthermore, some students may call his/her friend as “presence” nevertheless to the fact that this student is currently absent. After taking into consideration all these issues and the fact that many gadgets use Android platform, authors of the following research paper decided to create a mobile system that makes easier to check students’ attendance automatically, and this system is implemented in Almaty Management University, Kazakhstan. The system is based on Android platform, and in this paper, details of this system are presented.

    Full Text Available Abstract Background Screening for mental disorders among disability claimants is important, since mental disorders seem to be seriously under-recognized in this population. However, performance of potentially suitable scales is unknown. We aimed to evaluate the psychometric properties of three scales, the 10- and 6-item Kessler Psychological Distress Scale (K10, K6 and the 12-item General Health Questionnaire (GHQ-12, to predict present state mental disorders, classified according to the Diagnostic and Statistical Manual of Mental Disorders, 4thEdition (DSM-IV among disability claimants. Methods All scales were completed by a representative sample of persons claiming disability benefit after two years sickness absence (n=293. All diagnoses, both somatic and mental, were included. The gold standard was the Composite International Diagnostic Interview (CIDI 3.0 to diagnose present state DSM-IV disorder. Cronbach’s α, sensitivity, specificity, positive (PPV and negative predictive values (NPV, and the areas under the Receiver Operating Characteristic curve (AUC were calculated. Results Cronbach’s alpha’s were 0.919 (K10, 0.882 (K6 and 0.906 (GHQ-12. The optimal cut-off scores were 24 (K10, 14 ( K6 and 20 (GHQ-12. The PPV and the NPV for the optimal cut point of the K10 was 0.53 and 0.89, for the K6 0.51 and 0.87, and for the GHQ-12 0.50 and 0.82. The AUC’s for 30-day cases were 0.806 (K10; 95% CI 0.749-0.862, 0.796 (K6; 95% CI 0.737-0.854 and 0.695 (GHQ-12; 95% CI 0.626-0.765. Conclusions The K10 and K6 are reliable and valid scales to screen for present state DSM-IV mental disorder. The optimal cut-off scores are 24 (K10 and 14 (K6. The GHQ-12 (optimal cut-off score: 20 is outperformed by the K10 and K6, which are to be preferred above the GHQ-12. The scores on separate items of the K10 and K6 can be used in disability assessment settings as an agenda for an in-depth follow-up clinical interview to ascertain the presence of present state

    2012-05-01

    To maximize the contributions of nanotechnology to this society, at least 60 countries have put efforts into this field. In Taiwan, a government-funded K-12 Nanotechnology Programme was established to train K-12 teachers with adequate nanotechnology literacy to foster the next generation of Taiwanese people with sufficient knowledge in nanotechnology. In the present study, the Nanotechnology Attitude Scale for K-12 teachers (NAS-T) was developed to assess K-12 teachers' attitudes toward nanotechnology. The NAS-T included 23 Likert-scale items that can be grouped into three components: importance of nanotechnology, affective tendencies in science teaching, and behavioural tendencies to teach nanotechnology. A sample of 233 K-12 teachers who have participated in the K-12 Nanotechnology Programme was included in the present study to investigate the psychometric properties of the NAS-T. The exploratory factor analysis of this teacher sample suggested that the NAS-T was a three-factor model that explained 64.11% of the total variances. This model was also confirmed by the confirmatory factor analysis to validate the factor structure of the NAS-T. The Cronbach's alpha values of three NAS-T subscales ranged from 0.89 to 0.95. Moderate to strong correlations among teachers' NAS-T domain scores, self-perception of own nanoscience knowledge, and their science-teaching efficacy demonstrated good convergent validity of the NAS-T. As a whole, psychometric properties of the NAS-T indicated that this instrument is an effective instrument for assessing K-12 teachers' attitudes toward nanotechnology. The NAS-T will serve as a valuable tool to evaluate teachers' attitude changes after participating in the K-12 Nanotechnology Programme.

    Murphy, T.; Wegner, K.; Andersen, T. J.

    2016-12-01

    Twenty years ago, the Internet was still in its infancy, citizen science was a relatively unknown term, and the idea of a global citizen science database was unheard of. Then the Global Learning and Observations to Benefit the Environment (GLOBE) Program was proposed and this all changed. GLOBE was one of the first K-12 citizen science programs on a global scale. An initial large scale ramp-up of the program was followed by the establishment of a network of partners in countries and within the U.S. Now in the 21st century, the program has over 50 protocols in atmosphere, biosphere, hydrosphere and pedosphere, almost 140 million measurements in the database, a visualization system, collaborations with NASA satellite mission scientists (GPM, SMAP) and other scientists, as well as research projects by GLOBE students. As technology changed over the past two decades, it was integrated into the program's outreach efforts to existing and new members with the result that the program now has a strong social media presence. In 2016, a new app was launched which opened up GLOBE and data entry to citizen scientists of all ages. The app is aimed at fresh audiences, beyond the traditional GLOBE K-12 community. Groups targeted included: scouting organizations, museums, 4H, science learning centers, retirement communities, etc. to broaden participation in the program and increase the number of data available to students and scientists. Through the 20 years of GLOBE, lessons have been learned about changing the management of this type of large-scale program, the use of technology to enhance and improve the experience for members, and increasing community involvement in the program.

    2008-09-01

    The objective of the study was to determine whether a simulation-based educational program would improve residents' and attending physicians' performance in a simulated shoulder dystocia. Seventy-one obstetricians participated in an unanticipated simulated shoulder dystocia, an educational debriefing session, and a subsequent shoulder dystocia simulation. Each simulation was scored, based on standardized checklists for 4 technical maneuvers and 6 communication tasks, by 2 physician observers. Paired Student t tests were used for analysis. Forty-three attendings and 28 residents participated. Residents showed significant improvement in mean maneuver (3.3 +/- 0.9 vs 3.9 +/- 0.4, P = .001) and communication (3.5 +/- 1.2 vs 4.9 +/- 1.0, P < .0001) scores after simulation training. Attending physicians' communication (3.6 +/- 1.6 vs 4.9 +/- 1.1, P < .0001) scores were significantly improved after training. Our program improved physician performance in the management of simulated shoulder dystocia deliveries. Obstetric emergency simulation training can improve physicians' communication skills, at all levels of training, and should be incorporated into labor and delivery quality improvement measures.

    2017-06-01

    K-12 educators need effective and relevant astronomy professional development. NASA's Mission Science provides innovative and accessible opportunities for K-12 teachers. Science questions involve scale and distance, including Moon/Earth scale, solar system scale, and distance of objects in the universe. Teachers can gain an understanding of basic telescopes, the history of telescopes, ground and satellite based telescopes, and models of JWST Telescope. An in-depth explanation of JWST and Spitzer telescopes gave participants background knowledge for infrared astronomy observations. During teacher training, we taught the electromagnetic spectrum through interactive stations. The stations included an overview via lecture and power point, the use of ultraviolet beads to determine ultraviolet exposure, the study of lenticulars and diagramming of infrared data, looking at visible light through diffraction glasses and diagramming the data, protocols for using astronomy based research in the classroom, and infrared thermometers to compare environmental conditions around the observatory. An overview of LIDAR physics was followed up by a simulated LIDAR mapping of the topography of Mars.We will outline specific steps for K-12 infrared astronomy professional development, provide data demonstrating the impact of the above professional development on educator understanding and classroom use, and detail future plans for additional K-12 professional development.Funding was provided by Washington STEM, NASA, and the Washington Space Grant Consortium.

    Full Text Available The study aimed to characterize the educational services offered to students with physical disabilities in a Municipal Education of a midsize city of São Paulo state. We gathered the data through document analysis and application of semi-structured interviews. We recorded the data on audio, transcribed and analyzed them. We categorized them into two categories, the first of which referred to the attendance policies and second, the organization of care for students with physical disabilities. The results showed that the system investigated showed accessibility policies supporting the use of assistive technology for students with disabilities enrolled in regular education, despite not indicate the need for specialized educational services when the student has no associated cognitive impairment. We concluded that there are myriad factors to contemplate the school inclusion of students with physical disabilities and that many actions are needed to ensure education and social participation of this target audience.

  3. An examination of the identity development of African American undergraduate engineering students attending an HBCU

    Science.gov (United States)

    Taylor, Kenneth J.

    This study examined the identity development for a sample of 90 African American undergraduate engineering male and female students attending an HBCU. Using the Student Development Task and Lifestyle Assessment (SDTLA), which is based on Chickering and Reisser's identity development theory, differences in identity development were examined with respect to gender, academic classification, and grade point average. Previous research has shown the need to look beyond academic factors to understand and influence the persistence of African American engineering students. Non-cognitive factors, including identity development have proven to be influential in predicting persistence, especially for African American engineering students. Results from the analysis revealed significant means for academic classification and five of the dependent variables to include career planning peer relations, emotional autonomy, educational involvement, and establishing and clarifying purpose. Post hoc analysis confirmed significant differences for four of those dependent variables. However, the analysis failed to confirm statistical significant differences in peer relations due to academic classification. The significant decline in the mean scores for development in these four areas, as students progressed from sophomore to senior year revealed strong implications for the need to provide programming and guidance for those students. Institutions of higher education should provide more attention to the non-cognitive areas of development as a means of understanding identity development and working toward creating support systems for students.

    A criticism of incentives for health behaviors is that incentives undermine intrinsic motivation. The objective of this study was to determine the impact of monetary incentive provision on participation motives for exercise in first-year college students at a northeastern public university. Randomized-controlled trial. Public university in the Northeastern United States. One hundred seventeen first-year college students. Participants were randomized to one of three conditions: a control condition receiving no incentives for meeting fitness-center attendance goals; a discontinued-incentive condition receiving weekly incentives during fall semester 2011, and no incentives during spring semester 2012; or a continued-incentive condition receiving weekly incentives during fall semester, and incentives on a variable-interval schedule during spring semester. The Exercise Motivation Inventory 2 measured exercise participation motives at baseline, end of fall semester, and end of spring semester. Fitness-center attendance was monitored by using ID-card check-in/check-out records. Repeated-measures analyses using linear mixed models with first-order autoregressive covariance structures were run to compare motive changes in the three conditions. Participation motives of Enjoyment and Revitalization associated with intrinsic motivation did not decrease significantly over time in any of the conditions, F(4, 218) = 2.25, p = .065 and F(4, 220) = 1.67, p = .16, respectively. Intrinsically associated participation motives for exercise did not decrease with incentive provision. Therefore, incentives may encourage fitness-center attendance without negatively impacting participation motives for exercise.

    2018-06-01

    Full Text Available As the global demand for programmers is soaring, several countries have integrated programming into their K-12 curricula. Finding effective ways to engage children in programming education is an important objective. One effective method for this can be presenting learning materials via games, which are known to increase engagement and motivation. Current programming education games often focus on a single genre and offer one-size-fits-all experience to heterogeneous learners. In this study, we presented Minerva, a multi-genre (adventure, action, puzzle game to engage elementary school students in learning programming concepts. The game content is adapted to play and learning styles of the player to personalize the gameplay. We conducted a formative mixed-method evaluation of Minerva with 32 Korean 6th grade students who played the game and compared their learning outcomes with 32 6th grade students who studied the same concepts using handouts. The results indicated that, in terms of retention, learning was equally effective in both groups. Furthermore, the game was shown to facilitate engagement among the students. These results, together with uncovered issues, will guide Minerva’s further development.

    2014-12-01

    The Next Generation Science Standards (2014) will begin to change how K-12 teachers teach science. Using a scaffolding approach, the standards focus on a depth of knowledge across multiple content areas. This philosophy should encourage inquiry-based teaching methods, provided the teacher has both the knowledge and the confidence to teach the content. Although confidence to teach science is high among secondary science (biology, general science, chemistry) teachers, depth of knowledge may be lacking in certain areas, including climate science. To address this issue, a graduate course in climate science (Massachusetts Colleges Online Course of Distinction award winner) was developed to include inquiry-based instruction, connections to current research, and interdisciplinary approaches to teaching science. With the support of the InTeGrate program (SERC) at Carleton College, a module was developed to utilize cli-fi (climate science present in fictional literature) and related climate data. Graduate students gain an appreciation of scientific communication and an understanding of climate data and its connection to societal issues. In addition, the graduate students also gain the ability to connect interdisciplinary concepts for a deeper understanding of climate science and have the opportunity. By the end of the course, the graduate students use the content learned and the examples of pedagogical tools to develop their own activities in his or her classroom.

    Full Text Available Background: Methylphenidate hydrochloride (MPH is used in the treatment of attention deficit hyperactivity disorder (ADHD. The non-medical use of MPH by learners and students has been reported by numerous studies from abroad. The practice stems from beliefs about the benefits of MPH in achieving academic success. Little is known about the use of MPH in South African student populations. Objectives: The study set out to determine (1 the extent and dynamics associated with MPH use and (2 poly-substance use among undergraduate students attending a South African university. Methods: 818 students took part in a written, group-administered survey. Data analysis resulted in descriptive results regarding MPH use and tests of association identified differences in MPH and poly-substance use among respondents. Results: One in six respondents (17.2% has used MPH in the past, although only 2.9% have been diagnosed with ADHD. Nearly a third (31.7% of users obtained MPH products illegally. The majority (69.1% used MPH only during periods of academic stress. A significant association ( p < 0.001 was found between MPH use and the frequency of using alcohol, tobacco, cannabis, hard drugs (e.g. cocaine and prescription medication. Conclusion: MPH use among students appears similar to experiences abroad, especially in the absence of clinical diagnosis for ADHD. Institutions of higher education should inform parents and students about the health risks associated with the illicit use of MPH. Prescribers and dispensers of MPH products should pay close attention to practices of stockpiling medication and poly-substance use among students who use MPH.

  10. Observation of Λ-hypernuclei in the reaction 12C(π+,K+)/sub Λ/12C

    International Nuclear Information System (INIS)

    Milner, E.C.

    1985-12-01

    The observation of Λ-hypernuclear levels in /sub Λ/ 12 C by associated production through the (π + ,K + ) reaction is reported. Spectrometers used in the measurements are discussed. The /sub Λ/ 12 C excitation energy spectra were recorded at laboratory scattering angles of 5.6 0 , 10.3 0 , and 15.2 0 . The spectra show two major peaks - one attributed to the ground state, and one about 11 MeV higher in excitation. The peak near 11 MeV excitation energy is believed to be almost entirely composed of a multiplet of three J/sup π/ = 2 + states. Relativistic DWBA calculations imply support for the expectation that higher spin states are preferentially populated in the (π + ,K + ) reaction, compared to the (K - ,π - ) reaction in which lower spin states are excited. 29 refs., 40 figs

    The elastic scattering of negative K-mesons on the proton and on the neutron of the deuterium has been measured at six incident momenta equally spaced between 1.2 and 2.2 GeV/c. Differential cross sections over the almost complete angular range have been obtained for K/sup - /p and K/sup -/n. The aim of the experiment was the measurement of the pure isospin I=1 reaction K/sup -/n to K/sup -/n. The results for the reaction on proton are a by-product and provide a verification of the assumptions necessary for the analysis of the neutron reaction.

  13. Lon gene and photoprotection in Escherichia coli K-12

    Photoprotection, i.e. the increased resistance of the cells preilluminated with near ultraviolet light (300-380 nm) to the lethal action of 254nm radiations requires either an integrated prophage or a recA mutation in Escherichia coli K12 strains. Significant photoprotection occurs in an Escherichia coli K12 recA/sup +/ cell containing the lon allele responsible for filamentous growth after 254nm irradiation. The Fil phenotype can be suppressed by the sfiA or sfiB suppressor genes. Since the E. coli K12 recA/sup +/ lon sfiB strain exhibits no more photoprotection, it is concluded that in lon strains photoprotection is due to the abolition of the 254nm induced filamentation by the near ultraviolet treatment. In addition, near ultraviolet illumination of the cells leads to a severe restriction of the bulk protein synthesis. This effect is observed only in nuv/sup +/ cells that contain 4-thiouridine the chromophore responsible for photoprotection. It is proposed that in lon (lysogenic strains) photoprotection is due to prevention of the SOS response. During the growth lag, the low residual level of protein synthesis does not allow the induction of the SOS response and accordingly prevents filamentation (the lytic cycle).

    Ras gene plays an important role in the extra- and intra-cellular signal transduction pathway. It mediates series cascade reactions, and eventually actives transcriptional factors in nucleus. It is unknown on the mechanism of carcinogenesis of Ras gene in endometrial carcinoma, though K-ras mutant is very common in endometrial atypical hyperplasia and carcinoma. On basis of discovering the mutation in 12th codon of K-ras in endometrial carcinoma cell line, HEC-1A, we explored the carcinogenesis and molecular mechanism of mutant-type [12Asp] K-ras4B gene. (1) Full-length [12Asp]K-ras4B cDNA was amplified with RT-PCR, then inserted into pcDI eukaryotic expressive vector. (2) Morphological change, growth kinetics in vitro and tumorigencity in nude mice in vivo after-before transfection were observed.

  20. Climate Research by K-12 Students: Can They Do It? Will Anybody Care?

    Science.gov (United States)

    Brooks, D. R.

    2011-12-01

    Starting from the premise that engaging students in authentic science research is an activity that benefits science education in general, it is first necessary to consider whether students, in collaboration with teachers and climate scientists, can do climate-related research that actually has scientific value. A workshop held in November 2010, co-sponsored by NSF and NOAA, addressed this question. It took as its starting point this "scientific interest" test: "If students conduct a climate-related research project according to protocols designed in collaboration with climate scientists, when they get done, will any of those scientists care whether they did it or not?" If the answer to this question is "yes," then the project may constitute authentic research, but if the answer is "no," then the project may have educational value, but it is not research. This test is important because only when climate scientists (and other stakeholders interested in climate and climate change) are invested in the outcomes of student research will meaningful student research programs with sustainable support be forthcoming. The absence of climate-related projects in high-level student science fair competitions indicates that, currently, the investment and infrastructure required to support student climate research is lacking. As a result, climate science is losing the battle for the "hearts and minds" of today's best students. The critical task for student climate research is to define projects that are theoretically and practically accessible. This excludes the "big questions" of climate science, such as "Is Earth getting warmer?", but includes many observationally based projects that can help to refine our understanding of climate and climate change. The characteristics of collaborative climate research with students include: 1. carefully drawn distinctions between inquiry-based "learning about" activities and actual research; 2. an identified audience of potential stakeholders

  1. Computer program for the automated attendance accounting system

    Poulson, P.; Rasmusson, C.

    1971-01-01

    The automated attendance accounting system (AAAS) was developed under the auspices of the Space Technology Applications Program. The task is basically the adaptation of a small digital computer, coupled with specially developed pushbutton terminals located in school classrooms and offices for the purpose of taking daily attendance, maintaining complete attendance records, and producing partial and summary reports. Especially developed for high schools, the system is intended to relieve both teachers and office personnel from the time-consuming and dreary task of recording and analyzing the myriad classroom attendance data collected throughout the semester. In addition, since many school district budgets are related to student attendance, the increase in accounting accuracy is expected to augment district income. A major component of this system is the real-time AAAS software system, which is described.

    2018-04-01

    Tutoring centres are common in universities in the United States, but there are few published studies that statistically examine the effects of tutoring on student success. This study utilizes multiple regression analysis to model the effect of tutoring attendance on final course grades in Calculus I. Our model predicted that every three visits to the tutoring centre is correlated with an increase of a students' course grade by one per cent, after controlling for prior academic ability. We also found that for lower-achieving students, attending tutoring had a greater impact on final grades.

    Full Text Available There is no questioning that the way people live, interact, communicate, and conduct business is undergoing a profound, rapid change. This change is often referred to as the “digital revolution,” which is the advancement of technology from analog, electronic and mechanical tools to the digital tools available today. Moreover, technology has begun to change education, affecting how students acquire the skill sets needed to prepare for college and a career and how educators integrate digital technological instructional strategies to teach. Numerous studies have been published discussing the barriers of integrating technology, the estimated amount of investment that is needed in order to fully support educational technology, and, of course, the effectiveness of technology in the classroom. As such, this article presents a critical review of the transitions that technology integration has made over the years; the amount of resources and funding that has been allocated to immerse school with technology; and the conflicting results presented on effectiveness of using is technology in education. Through synthesis of selected themes, we found a plethora of technological instructional strategies being used to integrate technology into K-12 classrooms. Also, though there have been large investments made to integrate technology into K-12 classrooms to equip students with the skills needed to prepare for college and a career, the practical use of this investment has not been impressive. Lastly, several meta-analyses showed promising results of effectiveness of technology in the classroom. However, several inherent methodological and study design issues dampen the amount of variance that technology accounts for.

    2014-01-01

    released from the G-protein. Receptor-activated K+ currents desensitize in the sustained presence of agonist to avoid excessive effects on neuronal activity. Desensitization of K+ currents integrates distinct mechanistic underpinnings. GABAB receptor activity reduces protein kinase-A activity, which...... reduces phosphorylation of serine-892 in GABAB2 and promotes receptor degradation. This form of desensitization operates on the time scale of several minutes to hours. A faster form of desensitization is induced by the auxiliary subunit KCTD12, which interferes with channel activation by binding to the G......-protein βγ subunits. Here we show that the two mechanisms of desensitization influence each other. Serine-892 phosphorylation in heterologous cells rearranges KCTD12 at the receptor and slows KCTD12-induced desensitization. Likewise, protein kinase-A activation in hippocampal neurons slows fast...

    Full Text Available Students who identify as lesbian, gay, bisexual, or transgender (LGBT are at risk for harassment due to their sexual orientation or gender identification with over 85% of LGBT students in the United States (US reporting such harassment. These statistics demonstrate one aspect of the significance of this issue, but the cost of human life in some instances has revealed another layer of importance related to a need for safety policies for LGBT students. Even though a need exists for such policies, the practice of heteronormativity found in US policymaking regarding bullying does not protect victims or curb the violence. This essay highlights several recent developments in anti-bullying policy in US schools that shows the existence of heteronormativity, which is not helping to pro-tect LGBT students. By understanding the discrimination encouraged by current policy, future policy can be better shaped to protect LGBT students.

    To compare 12-year-old students from public and private schools in the city of Goiânia, Brazil, in terms of the prevalence of caries, periodontal conditions, dentofacial anomalies, and fluorosis. In 2003, the 2002-2003 Oral Health Conditions in the Brazilian Population project (SB Brasil) was expanded to Goiânia as a cross-sectional study, as described in the present article. The sample included 1 947 students from urban schools: 1 790 (91.9%) attended public schools and 157 (8.1%) attended private schools. Data on the following oral conditions were collected through clinical examination: dental caries (decayed, missing, or filled teeth index, DMFT), periodontal condition (Community Periodontal Index, CPI), dentofacial anomaly (Dental Aesthetics Index, DAI), and dental fluorosis (Dean index). The groups were compared using the chi-square and Mann-Whitney U tests. There were differences between the public and private schools for all the variables. DMFT, CPI, and DAI indexes were higher in children from public schools (P schools (P school was associated with the oral health condition of the children in this sample. Investments in actions and services to mitigate this inequality and its effects should be made as part of the policies to promote oral health.

  15. Attendroid : An Android Application in Attendance Management System

    Directory of Open Access Journals (Sweden)

    Lorissa Joana E. Buenas

    2015-11-01

    Full Text Available This research involves an android application in attendance management system. The study sought to provide an alternative solution to the increasing demand for time management in the College of Engineering and Computing Sciences in Batangas State University ARASOF. Through the said Android application the attendance checking will be much easier, for it will reduce the roll call that takes a lot of time. It was developed to help the lecturers have sufficient time for teaching and the students for learning. The researchers used research design, development process, and programming procedures in their study. The “Attendroid”, was designed and develop using Eclipse, Java Script, Php and HTML. This application is for android phones and tablet which has portable hotspot. The android application for the students will run on 2.2versions of android and higher. The android application has gone through an evaluation to test whether the system is acceptable in terms of security, accuracy, reliability, maintainability and user-friendliness against the manual checking of attendance. The result shows that the respondents are more favorable in the Attendroid because it can be gleaned that they gave an excellent feedback to the application compared to the manual process of attendance checking. After thorough study of the old ways of attendance checking against the newly developed application, a necessity to improve the manual checking was observed, and therefore, strengthen the advantages of implementing Attendroid. Based on the result of the proposed users’ acceptability, Attendroid could become the formal attendance checking system of the College of Engineering and Computing Sciences.

    2015-01-01

    Our aim was to examine the rates and predictors of father attendance at nurse home visits in replication sites of the Nurse-Family Partnership (NFP). Early childhood programs can facilitate father involvement in the lives of their children, but program improvements require an understanding of factors that predict father involvement. The sample consisted of 29,109 low-income, first-time mothers who received services from 694 nurses from 80 sites. We conducted mixed-model multiple regression analyses to identify population, implementation, site, and nurse influences on father attendance. Predictors of father attendance included a count of maternal visits (B = 0.12, SE = 0.01, F = 3101.77), frequent contact between parents (B = 0.61, SE = 0.02, F = 708.02), cohabitation (B = 1.41, SE = 0.07, F = 631.51), White maternal race (B = 0.77, SE = 0.06, F = 190.12), and marriage (B = 0.42, SE = 0.08, F = 30.08). Random effects for sites and nurses predicted father-visit participation (2.7 & 6.7% of the variance, respectively), even after controlling for population sociodemographic characteristics. These findings suggest that factors operating at the levels of sites and nurses influence father attendance at home visits, even after controlling for differences in populations served. Further inquiry about these influences on father visit attendance is likely to inform program-improvement efforts. PMID:25521707

    The Southeast has high rates of church attendance and HIV infection rates. We evaluated the relationship between church attendance and HIV viremia in a Southeastern US, HIV-infected cohort. Viremia (viral load ≥200 copies/ml) was analyzed 12 months after initiation of care. Univariate and multivariable logistic regression models were fit for variables potentially related to viremia. Of 382 patients, 74 % were virally suppressed at 12 months. Protective variables included church attendance (AOR 0.5; 95 % CI 0.2, 0.9), being on antiretroviral therapy (AOR 0.01; 95 % CI 0.004, 0.04), CD4(+) T lymphocyte count 200-350 cells/mm(3) at care entry (AOR 0.3; 95 % 0.1, 0.9), and education (AOR 0.5; 95 % CI 0.2, 0.9). Variables predicting viremia included black race (AOR 3.2; 95 % CI 1.4, 7.4) and selective disclosure of HIV status (AOR 2.7; 95 % CI 1.2, 5.6). Church attendance may provide needed support for patients entering HIV care for the first time. El Sur Este de los Estados Unidos tiene tasas altas de visitas a iglesias y de infección por VIH.

    1998-11-01

    Despite support by teachers, students, and the American public in general, environmental education is not a priority in U.S. schools. Teachers face many barriers to integrating environmental education into K--12 curricula. The focus of this research is teachers' lack of access to environmental education resources. New educational reforms combined with emerging mass communication technologies such as the Internet and World Wide Web present new opportunities for the infusion of environmental content into the curriculum. New technologies can connect teachers and students to a wealth of resources previously unavailable to them. However, significant barriers to using technologies exist that must be overcome to make this promise a reality. Web-based environmental education is a new field and research is urgently needed. If teachers are to use the Web meaningfully in their classrooms, it is essential that their attitudes and perceptions about using this new technology be brought to light. Therefore, this exploratory research investigates teachers' attitudes toward using the Web to share environmental education resources. Both qualitative and quantitative methods were used to investigate this problem. Two surveys were conducted---self-administered mail survey and a Web-based online survey---to elicit teachers perceptions and comments about environmental education and the Web. Preliminary statistical procedures including frequencies, percentages and correlational measures were performed to interpret the data. In-depth interviews and participant-observation methods were used during an extended environmental education curriculum development project with two practicing teachers to gain insights into the process of creating curricula and placing it online. Findings from the both the mail survey and the Web-based survey suggest that teachers are interested in environmental education---97% of respondents for each survey agreed that environmental education should be taught in K

    To better prepare tomorrow's leaders, it is of utmost importance that today's teachers are science literate. To meet that need, the American Meteorological Society (AMS) Education Program offers content-rich, professional development courses and training workshops for precollege teachers in the geosciences. During the fall and spring semesters, the AMS in partnership with NOAA, NASA, and SUNY Brockport, offers a suite of pre-college teacher development courses, DataStreme Atmosphere, DataStreme Ocean and DataStreme Earth's Climate System (ECS). These courses are delivered to small groups of K-12 teachers through Local Implementation Teams (LITs) positioned throughout the U.S. The courses use current, real-world environmental data to investigate the atmosphere, ocean, and climate system and consist of weekly online study materials, weekly mentoring, and several face-to-face meetings, all supplemented by a provided textbook and investigations manual. DataStreme ECS takes an innovative approach to studying climate science, by exploring the fundamental science of Earth's climate system and addressing the societal impacts relevant to today's students and teachers. The course investigates natural and human forcings and feedbacks to examine mitigation and adaptation strategies for the future. Information and data from respected organizations, such as the IPCC, the US Global Change Research Program, NASA, and NOAA are used throughout the course, including in the online and printed investigations. In addition, participants differentiate between climate, climate variability, and climate change through the AMS Conceptual Energy Model, a basic climate model that follows the flow of energy from space to Earth and back. Participants also have access to NASA's EdGCM, a research-grade Global Climate Model where they can explore various future climate scenarios in the same way that actual research scientists do. Throughout all of the courses, teachers have the opportunity to expand

    National data from Monitoring the Future were used to examine patterns and predictors of college attendance. Samples of American 12 th -grade students from 1977-2003 were followed for seven years (modal ages 18-25; N =10,020). College attendance and graduation patterns varied considerably over historical time and based on family background. Substance use during high school predicted a greater likelihood of never attending (for cigarettes, illegal drugs), of graduating from a 2-year rather than a 4-year school (for cigarettes), and of dropping out versus graduating from a 4-year school (for cigarettes, marijuana, and other illegal drugs). High school binge drinking predicted lower college dropout, but only in models also controlling for cigarette, marijuana, and other illicit drug use. This study provides a needed overview of adolescent predictors of patterns of college attendance among American young adults over the past three decades.

    PolarTREC (Teachers and Researchers Exploring and Collaborating) is a National Science Foundation (NSF) funded program in which K-12 teachers participate in hands-on field research experiences in the polar regions. PolarTREC highlights the importance of involving teachers in scientific research in regards to their careers as educators and their ability to engage students in the direct experience of science. To date, PolarTREC has placed over 90 teachers with research teams in the Arctic and Antarctic. Published results of our program evaluation quantify the effect of the field experience on the teachers' use of the real scientific process in the classroom, the improvement in science content taught in classrooms, and the use of non-fiction texts (real data and science papers) as primary learning tools for students. Teachers and students both report an increase of STEM literacy in the classroom content, confidence in science education, as well as a markedly broadened outlook of science as essential to their future. Research conducted with science teams affirms that they are achieving broader impacts when PolarTREC teachers are involved in their expeditions. Additionally, they reported that these teachers making vital contributions to the success of the scientific project.

  8. Effects of paraquat on Escherichia coli: Differences between B and K-12 strains

    1990-01-01

    Escherichia coli B and K-12 are equally susceptible to the bacteriostatic effects of aerobic paraquat, but they differed strikingly when the lethality of paraquat was evaluated. E. coli B suffered an apparent loss of viability when briefly exposed to paraquat, whereas E. coli K-12 did not. This difference depended on the ability of the B-strain, but not the K-12 strain, to retain internalized paraquat; the B strain was killed on aerobic tryptic soy-yeast extract plates during the incubation which preceded the counting of colonies. This difference in retention of paraquat between strains was demonstrated by delayed loss of viability, by growth inhibition, and by cyanide-resistant respiration after brief exposure to paraquat, washing, and testing in fresh medium. This difference was also shown by using [ 14 C]paraquat. This previously unrecognized difference between E. coli B and K-12 has been the cause of apparently contradictory reports and should lead to some reevaluation of the pertinent literature

  9. Developing Partnerships between Higher Education Faculty, K-12 Science Teachers, and School Administrators via MSP initiatives: The RITES Model

    2011-12-01

    The Rhode Island Technology Enhanced Science Project (RITES) is a NSF-funded Math and Science Partnership (MSP) project that seeks to improve science education. RITES is, at its core, a unique partnership that fosters relationships between middle and high school science teachers, district and school administrators, higher education (HE) faculty members, and science education researchers. Their common goal is to enhance scientific inquiry, increase classroom technology usage, and improve state level science test scores. In one of the more visible examples of this partnership, middle and high school science teachers work closely with HE science faculty partners to design and teach professional development (PD) workshops. The PD sessions focus on technology-enhanced scientific investigations (e.g. use of probes, online simulations, etc.), exemplify inquiry-based instruction, and relate expert content knowledge. Teachers from these sessions express substantial satisfaction in the program, report increased comfort levels in teaching the presented materials (both via post-workshop surveys), and show significant gains in content knowledge (via pre-post assessments). Other benefits to this kind of partnership, in which K-12 and HE teachers are considered equals, include: 1) K-12 teachers are empowered through interactions with HE faculty and other science teachers in the state; 2) HE instructors become more informed not only about good pedagogical practices, but also practical aspects of teaching science such as engaging students; and 3) the PD sessions tend to be much stronger than ones designed and presented solely by HE scientists, for while HE instructors provide content expertise, K-12 teachers provide expertise in K-12 classroom practice and implementation. Lastly, the partnership is mutually beneficial for the partners involved because both sides learn practical ways to teach science and inquiry at different levels. In addition to HE faculty and K-12 science teacher

    Graphical abstract: - Highlights: • Encapsulation of Li, Na and K narrow the HOMO–LUMO gaps of the clusters. • The group III nitrides nanoclusters strongly interacted with the alkali metals. • First hyperpolarizabilities remarkably enhance for B{sub 12}N{sub 12} encapsulated with Na/K. - Abstract: Density functional theory (DFT) calculations have been carried out to study the influence of alkali metals (Li, Na and K) encapsulation within the group III nitrides (B{sub 12}N{sub 12}, Al{sub 12}N{sub 12} and Ga{sub 12}N{sub 12}) and the group IV carbides (C{sub 24}, Si{sub 12}C{sub 12}and Ge{sub 12}C{sub 12}) nanoclusters. The encapsulation of Li, Na and K atoms is found to narrow the HOMO–LUMO gaps of the considered clusters. The electronic properties of these clusters, especially the group III nitrides nanoclusters, are strongly sensitive to interaction with the alkali metals. Moreover it is observed that the encapsulation of alkali metals enhances the first hyperpolarizabilities of B{sub 12}N{sub 12} nanocluster. Surprisingly, due to the alkali metals encapsulation within B{sub 12}N{sub 12} nanocluster, the first hyperpolarizability values are remarkably increased to 8505.49 and 122,503.76 a.u. for Na@B{sub 12}N{sub 12} and K@B{sub 12}N{sub 12}, respectively. Also the TD-DFT calculations at both CAM-B3LYP/6-311+G(d) and PBE0/6-311+G(d) levels of theory are also performed to investigate the origin of first hyperpolarizabilities.

  11. "Flipping" educational technology professional development for K-12 educators

    Science.gov (United States)

    Spencer, Daniel

    As the demand for more effective professional development increases in K-12 schools, trainers must adjust their training methods to meet the needs of their teacher learners. Just as lecture-heavy, teacher-centered instruction only meet the learning needs of a small minority of students, "sit and get" professional development rarely results in the teachers gaining the skills and confidence necessary to use technology effectively in their instruction. To resolve the frustrations of teachers related to ineffective professional development, a "Flipped PD" training model was developed based on the learning needs of adult learners, the integration of technological, pedagogical, and content knowledge (TPACK), learning activities, and the Flipped Classroom concept. Under this model, training shifts from a passive, trainer-centered format, to an active, learner-centered format where teachers learn to use technology in their classrooms by first focusing on pedagogical issues, then choosing the options that work best for addressing those issues in their unique situation, and completing "learn-by-doing" projects. Those who participate in "Flipped PD" style trainings tend to have more confidence upon completion that they can use the tools they were trained on in their teaching, as well as believe that the PD was engaging and a good use of their time.

    The present study examined effects of sex, attitude towards physical activity, perceived barriers for participation in physical activity, and students' perception of their parents' participation in physical activity on the intrinsic motivation of students participating in a health related program in physical education. 643 students (303 boys and 340 girls) responded to questionnaires measuring intrinsic motivation, attitudes towards physical activity, perceived barriers to exercise and perceived parents' participation in physical activity. Mean age was 12.9 yr. (SD=1.2, range 11-14 years). Analysis indicated that students' intrinsic motivation towards the program was influenced by perceived barriers to exercise. Sex, attitudes towards physical activity, and perceived parents' participation in physical activity seem to be less important.

    The process of medical education, particularly in the fast evolving new era of medical metaschools, is a broad and complex issue. Harden & Crosby claimed that a good teacher is more than a lecturer, and identified 12 roles that certify a good and capable teacher. However, this is only half the truth: the good student is more than a listener. Teaching-and-learning is not simply a one-way process, and, as medical students are not children, the relationship between teacher and students involves andragogy rather than pedagogy. We therefore propose the 12+1 roles of the student. SUMMARY OF WORK: The Harden & Crosby paper was distributed in a class of 90 third year Ioannina University medical students, who were asked to think about the student's roles. A small discussion group brainstormed ideas, which were then refined further by the authors. 12+1 roles of the good medical student were produced and grouped into six areas: information receiver, in lectures and clinical context; role model in learning, in class, with the added subarea of comparative choice of role models; teaching facilitator and teacher's mentor; teacher's assessor and curriculum evaluator; active participator and keeping-up with curriculum; resource consumer/co-creator and medical literature researcher. The ideal student should fulfil the majority if not all of these complementary roles. These 12+1 student's roles are complementary to the 12 roles of the teacher and help reshaping our understanding of today's medical education process.

    2007-12-01

    Scientific discovery is the impetus for the K-4 Education program, "Reading, Writing & Rings." This program is unique because its focus is to engage elementary students in reading and writing to strengthen these basic academic skills through scientific content. As science has been increasingly overtaken by the language arts in elementary classrooms, the Cassini Education Program has taken advantage of a new cross-disciplinary approach to use language arts as a vehicle for increasing scientific content in the classroom. By utilizing the planet Saturn and the Cassini-Huygens mission as a model in both primary reading and writing students in these grade levels, young students can explore science material while at the same time learning these basic academic skills. Content includes reading, thinking, and hands-on activities. Developed in partnership with the Cassini-Huygens Education and Public Outreach Program, the Bay Area Writing Project/California Writing Project, Foundations in Reading Through Science & Technology (FIRST), and the Caltech Pre-College Science Initiative (CAPSI), and classroom educators, "Reading, Writing & Rings" blends the excitement of space exploration with reading and writing. All materials are teacher developed, aligned with national science and language education standards, and are available from the Cassini-Huygens website: http://saturn.jpl.nasa.gov/education/edu-k4.cfm Materials are divided into two grade level units. One unit is designed for students in grades 1 and 2 while the other unit focuses on students in grades 3 and 4. Each includes a series of lessons that take students on a path of exploration of Saturn using reading and writing prompts.

  5. The lon gene and photoprotection in Escherichia coli K-12

    International Nuclear Information System (INIS)

    Waksman, G.; Thomas, G.; Favre, A.

    1984-01-01

    Photoprotection, i.e. the increased resistance of the cells preilluminated with near ultraviolet light (300-380 nm) to the lethal action of 254nm radiations requires either an integrated prophage or a recA mutation in Escherichia coli K12 strains. Significant photoprotection occurs in an Escherichia coli K12 recA + cell containing the lon allele responsible for filamentous growth after 254nm irradiation. The Fil phenotype can be suppressed by the sfiA or sfiB suppressor genes. Since the E. coli K12 recA + lon sfiB strain exhibits no more photoprotection, it is concluded that in lon strains photoprotection is due to the abolition of the 254nm induced filamentation by the near ultraviolet treatment. In addition, near ultraviolet illumination of the cells leads to a severe restriction of the bulk protein synthesis. This effect is observed only in nuv + cells that contain 4-thiouridine the chromophore responsible for photoprotection. It is proposed that in lon (lysogenic strains) photoprotection is due to prevention of the SOS response. During the growth lag, the low residual level of protein synthesis does not allow the induction of the SOS response and accordingly prevents filamentation (the lytic cycle). (author)

    Full Text Available OBJECTIVE: To investigate the relationship between religiosity and drug use among Brazilian university students. METHODS: This manuscript is part of the "First Nationwide Survey on the Use of Alcohol, Tobacco and Other Drugs among College Students in the 27 Brazilian State Capitals". In this study, 12,595 university students were divided into two groups according to their attendance at religious services: frequent attenders (FR; 39.1% and non-frequent attenders (NFR; 60.8%. Subsequently, we analyzed their responses to a structured, anonymous questionnaire on drug use and other behaviors. Individual multivariate logistic regression models tested the association between religiosity and drug use (alcohol, tobacco, marijuana and at least one illicit drug. RESULTS: Drug use over the last 30 days was higher among NFR students even after controlling for demographic variables. NFR students were more likely to use alcohol OR = 2.52; 95% CI: 2.08-3.06, tobacco (2.83; 2.09-3.83, marijuana (2.09; 1.39-3.11 and at least one illicit drug (1.42; 1.12-1.79 compared to FR students. CONCLUSION: Religiosity was found to be a strongly protective factor against drug use among Brazilian university students. However, more studies are needed to identify the mechanisms by which religiosity exerts this protective influence.

    1996-01-01

    We study CP-conserving and CP-violating K 0 →ππ and K 0 →ππγ decays, using the same techniques which explain the ΔI=1/2 enhancement of the former to also explore CP violation of the latter transitions. If CP violation is driven by the WWγ vertex, we show that direct CP violation in K L →ππγ is scaled to the s→dγ E1 quark transition and the latter is suppressed by the GIM mechanism (compatible with recent experiments). In the same spirit, the dominant ΔI=1/2 enhancement of CP-conserving kaon weak decays can be scaled to an s→d quark transition which is enhanced by the GIM mechanism. copyright 1996 The American Physical Society

  13. The influence of excess K2O on the electrical properties of (K,Na)1/2Bi1/2TiO3 ceramics

    Li, Linhao; Li, Ming; Sinclair, Derek C.

    2018-04-01

    The solid solution (KxNa0.50-x)Bi0.50TiO3 (KNBT) between Na1/2Bi1/2TiO3 and K1/2Bi1/2TiO3 (KBT) has been extensively researched as a candidate lead-free piezoelectric material because of its relatively high Curie temperature and good piezoelectric properties, especially near the morphotropic phase boundary (MPB) at x ˜ 0.10 (20 mol. % KBT). Here, we show that low levels of excess K2O in the starting compositions, i.e., (Ky+0.03Na0.50-y)Bi0.50TiO3.015 (y-series), can significantly change the conduction mechanism and electrical properties compared to a nominally stoichiometric KNBT series (KxNa0.50-x)Bi0.50TiO3 (x-series). Impedance spectroscopy measurements reveal significantly higher bulk conductivity (σb) values for y ≥ 0.10 samples [activation energy (Ea) ≤ 0.95 eV] compared to the corresponding x-series samples which possess bandgap type electronic conduction (Ea ˜ 1.26-1.85 eV). The largest difference in electrical properties occurs close to the MPB composition (20 mol. % KBT) where y = 0.10 ceramics possess σb (at 300 °C) that is 4 orders of magnitude higher than that of x = 0.10 and the oxide-ion transport number in the former is ˜0.70-0.75 compared to processing. This demonstrates the electrical properties of KNBT to be sensitive to low levels of A-site nonstoichiometry and indicates that excess K2O in KNBT starting compositions to compensate for volatilisation can lead to undesirable high dielectric loss and leakage currents at elevated temperatures.

    Overexpression of heterogeneous nuclear ribonucleoprotein K (hnRNP K), a DNA/RNA binding protein, is associated with metastasis in nasopharyngeal carcinoma (NPC). However, the mechanisms underlying hnRNP K-mediated metastasis is unclear. The aim of the present study was to determine the role of matrix metalloproteinase (MMP) in hnRNP K-mediated metastasis in NPC. We studied hnRNP K-regulated MMPs by analyzing the expression profiles of MMP family genes in NPC tissues and hnRNP K-knockdown NPC cells using Affymetrix microarray analysis and quantitative RT-PCR. The association of hnRNP K and MMP12 expression in 82 clinically proven NPC cases was determined by immunohistochemical analysis. The hnRNP K-mediated MMP12 regulation was determined by zymography and Western blot, as well as by promoter, DNA pull-down and chromatin immunoprecipitation (ChIP) assays. The functional role of MMP12 in cell migration and invasion was demonstrated by MMP12-knockdown and the treatment of MMP12-specific inhibitor, PF-356231. MMP12 was overexpressed in NPC tissues, and this high level of expression was significantly correlated with high-level expression of hnRNP K (P = 0.026). The levels of mRNA, protein and enzyme activity of MMP12 were reduced in hnRNP K-knockdown NPC cells. HnRNP K interacting with the region spanning −42 to −33 bp of the transcription start site triggered transcriptional activation of the MMP12 promoter. Furthermore, inhibiting MMP12 by MMP12 knockdown and MMP12-specific inhibitor, PF-356231, significantly reduced the migration and invasion of NPC cells. Overexpression of MMP12 was significantly correlated with hnRNP K in NPC tissues. HnRNP K can induce MMP12 expression and enzyme activity through activating MMP12 promoter, which promotes cell migration and invasion in NPC cells. In vitro experiments suggest that NPC metastasis with high MMP12 expression may be treated with PF-356231. HnRNP K and MMP12 may be potential therapeutic markers for NPC, but

  16. Code to Learn: Where Does It Belong in the K-12 Curriculum?

    Directory of Open Access Journals (Sweden)

    Full Text Available The introduction of computer programming in K-12 has become mainstream in the last years, as countries around the world are making coding part of their curriculum. Nevertheless, there is a lack of empirical studies that investigate how learning to program at an early age affects other school subjects. In this regard, this paper compares three quasi-experimental research designs conducted in three different schools (n=129 students from 2nd and 6th grade, in order to assess the impact of introducing programming with Scratch at different stages and in several subjects. While both 6th grade experimental groups working with coding activities showed a statistically significant improvement in terms of academic performance, this was not the case in the 2nd grade classroom. Notable disparity was also found regarding the subject in which the programming activities were included, as in social studies the effect size was double that in mathematics.

  17. Neutron inelastic sattering from liquid 3He at 40 mK and at 1.2 K

    International Nuclear Information System (INIS)

    Skoeld, K.; Pelizzari, C.A.

    1978-01-01

    In a previous neutron scattering experiment on 3 He at T = 15 mK the present authors observed two peaks in the scattering function which were identified as the zero sound mode and the spin-fluctuation peak respectively. These results are different from those obtained by others at T = 0.63 K in which case no such structure was observed. In order to determine whether this discrepancy is due to the difference in the temperature of the two experiments, measurements have now been made at T = 40 mK and at T = 1.2 K. These results show that the two-peak structure persists at the higher temperature although measurable broadening is observed in the spin-fluctuation part of the spectrum. (author)

  18. High-Performance Schools: Affordable Green Design for K-12 Schools; Preprint

    Energy Technology Data Exchange (ETDEWEB)

    Plympton, P.; Brown, J.; Stevens, K.

    2004-08-01

    Schools in the United States spend $7.8 billion on energy each year-more than the cost of computers and textbooks combined, according to a 2003 report from the National Center for Education Statistics. The U.S. Department of Energy (DOE) estimates that these high utility bills could be reduced as much as 25% if schools adopt readily available high performance design principles and technologies. Accordingly, hundreds of K-12 schools across the country have made a commitment to improve the learning and teaching environment of schools while saving money and energy and protecting the environment. DOE and its public- and private-sector partners have developed Energy Design Guidelines for High Performance Schools, customized for nine climate zones in U.S. states and territories. These design guidelines provide information for school decision makers and design professionals on the advantages of energy efficiency and renewable energy designs and technologies. With such features as natural day lighting, efficient electric lights, water conservation, and renewable energy, schools in all types of climates are proving that school buildings, and the students and teachers who occupy them, are indeed high performers. This paper describes high performance schools from each of the nine climate zones associated with the Energy Design Guidelines. The nine case studies focus on the high performance design strategies implemented in each school, as well as the cost savings and benefits realized by students, faculty, the community, and the environment.

  4. Teaching Experiences for Graduate Student Researchers: A Study of the Design and Implementation of Science Courses for Secondary Students

    Science.gov (United States)

    Collins, Anne Wrigley

    Modern science education reform recommends that teachers provide K-12 science students a more complete picture of the scientific enterprise, one that lies beyond content knowledge and centers more on the processes and culture of scientists. In the case of Research Experience for Teachers (RET) programs, the "teacher" becomes "researcher" and it is expected that he/she will draw from the short-term science research experience in his/her classroom, offering students more opportunities to practice science as scientists do. In contrast, this study takes place in a program that allows graduate students, engaged in research full-time, to design and implement a short-duration course for high school students on Saturdays; the "researcher" becomes "teacher" in an informal science program. In this study, I investigated eleven graduate students who taught in the Saturday Science (SS) program. Analyses revealed participants' sophisticated views of the nature of science. Furthermore, participants' ideas about science clearly resonated with the tenets of NOS recommended for K-12 education (McComas et al., 1998). This study also highlighted key factors graduate students considered when designing lessons. Instructors took great care to move away from models of traditional, "lecture"-based, university science teaching. Nonetheless, instruction lacked opportunities for students to engage in scientific inquiry. In instances when instructors included discussions of NOS in SS courses, opportunities for high school students to learn NOS were not explicit enough to align with current science reform recommendations (e.g., AAAS, 2009). Graduate students did, however, offer high school students access to their own science or engineering research communities. These findings have significant implications for K-12 classroom reform. Universities continue to be a valuable resource for K-12 given access to scientists, materials or equipment, and funding. Nonetheless, and as was the case with

    Seventy-seven frequent attenders at an emergency department (ED) in an inner-city hospital in the UK (defined as seven or more visits in the previous 12 months) were compared with 182 patients who were attending the same department on a routine basis. Patients completed the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) and the Short Form (SF)-36. Information was obtained on 64% of the frequent attenders and 45% underwent a detailed psychiatric assessment. Of the frequent attenders, 45% had psychiatric disorder and 49% had some form of an alcohol-related disorder. Compared with routine attenders, frequent attenders reported lower health status, had more psychiatric disorder (odds ratio: OR=8.2, 95% confidence interval: CI=3.8--18.1), had more general hospital admissions (OR=19.9, 95% CI=8.3--47.8), more psychiatric admissions (OR=167.5, 95% CI=9.5--2959.0), and more GP visits (95% CI for difference=-10.2 to -5.7). There was no evidence that frequent attenders had more somatisation than routine attenders. Specific treatment and management strategies need to be developed for this group of patients, although a substantial proportion may be difficult to engage in the treatment process.

    2017-12-01

    Engaging communities with renewable energy is key to fighting climate change. Cycle for Science, an innovative STEM outreach organization, has reached more than 3,000 K-12 students across the United States by bringing early-career female scientists into classrooms to teach basic physics and solar energy engineering through hands-on, DIY science activities. We designed a fleet of miniature, 3D-printed, solar-powered bicycles called "Sol Cycles" to use as teaching tools. Traveling by bicycle, Cycle for Science has brought them to rural and urban communities across the U.S. in two major efforts so far: one traversing the country (2015), and one through central California (2017). The program involves (1) introducing the scientists and why they value science, (2) running a skit to demonstrate how electrons and photons interact inside the solar panel, (3) assembling the Sol Cycles, (4) taking students outdoors to test the effects of variables (e.g. light intensity) on the Sol Cycles' movement, (5) and debriefing about the importance of renewable energy. In addition to physics and solar energy, the lessons teach the scientific process, provide tactile engagement with science, and introduce a platform to engage students with climate change impacts. By cycling to classrooms, we provide positive examples of low-impact transportation and a unique avenue for discussing climate action. It was important that this program extend beyond the trips, so the lesson and Sol Cycle design are open source to encourage teachers and students to play, change and improve the design, as well as incorporate new exercises (e.g. could you power the bicycle by wind?). Additionally, it has been permanently added to the XRaise Lending Library at Cornell University, so teachers across the world can implement the lesson. By sharing our project at AGU, we aim to connect with other scientists, educators, and concerned citizens about how to continue to bring renewable energy lessons into classrooms.

    2015-12-01

    We present an update on our developing Virtual Ice Sheet Laboratory (VISL). Geared to K-12 classrooms and the general public, VISL's main goal is to improve climate literacy, especially in regards to the crucial role of the polar ice sheets in Earth's climate and sea level. VISL will allow users to perform guided experiments using the Ice Sheet System Model (ISSM), a state-of-the-art ice flow model developed at NASA's Jet Propulsion Laboratory and UC Irvine that simulates the near-term evolution of the ice sheets on Greenland and Antarctica. VISL users will access ISSM via a graphical interface that can be launched from a web browser on a computer, tablet or smart phone. Users select climate conditions and run time by moving graphic sliders then watch how a given region evolves in time under those conditions. Lesson plans will include conceptual background, instructions for table top experiments related to the concepts addressed in a given lesson, and a guide for performing model experiments and interpreting their results. Activities with different degrees of complexity will aim for consistency with NGSS Physical Science criteria for different grade bands (K-2, 3-5, 6-8, and 9-12), although they will not be labeled as such to encourage a broad user base. Activities will emphasize the development of physical intuition and critical thinking skills, understanding conceptual and computational models, as well as observation recording, concept articulation, hypothesis formulation and testing, and mathematical analysis. At our present phase of development, we seek input from the greater science education and outreach communities regarding VISL's planned content, as well as additional features and topic areas that educators and students would find useful.

    Evaluate the educational and exposure opportunities provided to students by national otolaryngology organizations. Twenty-four otolaryngology organizations and subspecialty societies were reviewed for medical student involvement opportunities, educational and enrichment opportunities, costs of involvement, and available research and travel scholarships. Nine organizations (37.5%) offered membership; 6 charged a membership fee, averaging $73 ± $30 (mean ± SD). Membership was limited to associate status for 7 organizations (77.8%; 7/9). Three organizations (12.5%) provided service opportunities, 4 (16.7%) allowed students to vote, and 1 (4.2%) allowed students to endorse others for membership. Most organizations allowed students to attend conferences (95.8%), and 19 (79.2%) allowed students to present research. Twenty-one (87.5%) organizations charged a conference registration fee ($366 ± $300). Seven organizations (29.2%) offered research scholarships, and 5 (20.8%) offered travel awards. Opportunities exist for medical students to attend conferences and present research; however, educational and enrichment activities in other areas were limited. Future efforts may be warranted to increase the number and type of opportunities for students.

    Perry, R. B.; Hamner, W. M.

    2006-12-01

    OceanGLOBE is an outdoor environmental research and education program for upper elementary, middle and high school students, supplemented by online instructional materials that are available without charge to any educator. OceanGLOBE was piloted in 1995 with support from a National Science Foundation Teacher Enhancement project, "Leadership in Marine Science" (award no.ESI-9454413 to UCLA). Continuing support by a second NSF Teacher Enhancement project (award no. ESI-9819424 to UCLA) and by COSEE-West (NSF awards OCE-215506 to UCLA and OCE-0215497 to USC) has enabled OceanGLOBE to expand to a growing number of schools and to provide an increasingly robust collection of marine science instructional materials on its website, http://www.msc.ucla.edu/oceanglobe/ OceanGLOBE provides a mechanism for students to conduct inquiry-based, hands-on marine science research, providing experiences that anchor the national and state science content standards learned in the classroom. Students regularly collect environmental and biological data from a beach site over an extended period of time. In the classroom they organize, graph and analyze their data, which can lead to a variety of student-created science products. Beach research is supported by instructional marine science materials on the OceanGLOBE website. These online materials also can be used in the classroom independent of the field component. Annotated PowerPoint slide shows explain research protocols and provide marine science content. Field guides and photographs of marine organisms (with emphasis on the Southern California Bight) and a growing collection of classroom investigations (applicable to any ocean location) support the science content presented in the beach research program and slide shows. In summary, OceanGLOBE is a comprehensive learning package grounded in hands-on, outdoor marine science research project in which students are the principal investigators. By doing scientific work repetitively over an

    Chambers, L. H.; Chaudhury, S.; Page, M. T.; Lankey, A. J.; Doughty, J.; Kern, Steven; Rogerson, Tina M.

    2008-01-01

    During the summer of 2007, as part of the second year of a NASA-funded project in partnership with Christopher Newport University called SPHERE (Students as Professionals Helping Educators Research the Earth), a group of undergraduate students spent 8 weeks in a research internship at or near NASA Langley Research Center. Three students from this group formed the Clouds group along with a NASA mentor (Chambers), and the brief addition of a local high school student fulfilling a mentorship requirement. The Clouds group was given the task of exploring and analyzing ground-based cloud observations obtained by K-12 students as part of the Students' Cloud Observations On-Line (S'COOL) Project, and the corresponding satellite data. This project began in 1997. The primary analysis tools developed for it were in FORTRAN, a computer language none of the students were familiar with. While they persevered through computer challenges and picky syntax, it eventually became obvious that this was not the most fruitful approach for a project aimed at motivating K-12 students to do their own data analysis. Thus, about halfway through the summer the group shifted its focus to more modern data analysis and visualization tools, namely spreadsheets and Google(tm) Earth. The result of their efforts, so far, is two different Excel spreadsheets and a Google(tm) Earth file. The spreadsheets are set up to allow participating classrooms to paste in a particular dataset of interest, using the standard S'COOL format, and easily perform a variety of analyses and comparisons of the ground cloud observation reports and their correspondence with the satellite data. This includes summarizing cloud occurrence and cloud cover statistics, and comparing cloud cover measurements from the two points of view. A visual classification tool is also provided to compare the cloud levels reported from the two viewpoints. This provides a statistical counterpart to the existing S'COOL data visualization tool

  16. Thinking Like a Scientist: The RITES Path for K-12 Students to Learn the Scientific Method

    Science.gov (United States)

    Murray, D. P.; Dooley, H., Jr.; Cardace, D.

    2015-12-01

    Bringing Research on Learning to the Geosciences (Manduca et al, 2002) stated that "An overaching goal for geoscience education is to help every student to 'think like a scientist'", and that continues to challenge geoscience education. The Rhode Island Technology Enhanced Science (RITES) project addresses that goal, and this presentation chronicles that successful effort. RITES strives to improve science education by providing professional development (PD) to the majority of science teachers at the 5th through 12th grade levels throughout Rhode Island. The PD is presented through ~forty 2.5 day workshops that emphasize the innovative use of technology and best teaching practices, consistent with the recommendations detailed in Manduca et al (2002). The presentation will focus on two of these workshops that provide middle and high school teachers with strategies and techniques for guiding student-run explorations of earthquakes as a result of tectonic plate movements. Teachers address these topics much as a scientist would by carrying out the following activities: 1) Identifying the relationships between faults, EQs and plate boundaries; 2) Using GPS data to quantify interseismic deformation; 3) Constructing an Earthquake machine; and 4) Scaling their observations from desktop to crustal scale, and (5) Using the results to forecast earthquakes along the SAF and to estimate the magnitude of earthquakes on ancient faults. As it is unrealistic to expect teachers to be able to incorporate all of this material into their syllabi, we have introduced the concept of Subtle Shifts (Exploratorium, 2006) as a means by which they can easily blend workshop material into their existing courses. Teacher surveys reflect a high level of satisfaction (81-100%), and pre- and post-evaluations show significant normalized gains (Hake, 1998), in about 90% of the courses. Moreover, students of RITES teachers demonstrate statistically significant gains in inquiry skills and content

    McCarthy, K.

    2017-12-01

    NASA's Operation IceBridge (OIB), the largest airborne survey of Earth's polar ice uses remote sensing methods to collect data on changing sea and land ice. PolarTREC teacher Kelly McCarthy joined the team during the 2016 Spring Arctic Campaign. This presentation explores ways in which k-12 students were engaged in the work being done by OIB through classroom learning experiences, digital communications, and independent research. Initially, digital communication including chats via NASA's Mission Tools Suite for Education (MTSE) platform was leveraged to engage students in the daily work of OIB. Two lessons were piloted with student groups during the 2016-2017 academic year both for students who actively engaged in communications with the team during the expedition and those who had no prior connections to the field. All of the data collected on OIB missions is stored for public use in a digital portal on the National Snow and Ice Data Center (NSIDC) website. In one lesson, 10th-12th grade students were guided through a tutorial to learn how to access data and begin to develop a story about Greenland's Jakobshavn Glacier using pre-selected data sets, Google's MyMaps app, and independent research methods. In the second lesson, 8th grade students were introduced to remote sensing, first through a discussion on vocabulary using productive talk moves and then via a demonstration using Vernier motion detectors and a graph matching simulation. Students worked in groups to develop procedures to map a hidden surface region (boxed assortment of miscellaneous objects) using a Vernier motion sensor to simulate sonar. Students translated data points collected from the motion sensor into a vertical profile of the simulated surface region. Both lessons allowed students a way to engage in two of the most important components of OIB. The ability to work with real data collected by the OIB team provided a unique context through which students gained skill and overcame challenges in

    Geleto, Ayele; Markos, Jote

    2015-03-17

    Unsafe abortion has been recognized as an important public health problem in the world. It accounts for 14% of all maternal deaths in sub-Saharan African countries. In Ethiopia, 32% of all maternal deaths are accounted to unsafe abortion. Taking the problem of unsafe abortion into consideration, the penal code of Ethiopia was amended in 2005, to permit safe abortion under a set of circumstances. However, lack of awareness on the revised penal code is a major barrier that hinders women to seek safe abortion. The aim of this study is to assess awareness of female students attending higher educational institutions toward legalization of safe abortion and associated factors in Harari region, eastern Ethiopia. Institution-based descriptive cross sectional study was conducted among 762 female students who are attending five higher educational institutions in Harari Region. Systematic sampling method was used to identify study participants from randomly selected colleges. Self administered structured questionnaire was used to collect data. Data were entered in to Epi Info version 6.04 and analyzed by SPSS version 17.0 statistical packages. Frequency, percentage and ratio were used to describe variables. Multivariable logistic regression analysis was done to control confounders and odds ratio with 95% confidence interval was used to identify factors associated with awareness of female students to legalization of abortion. 762 study participants completed the survey questionnaire making the response rate 90.2%. Only 272 (35.7%) of the respondents reported that they have good awareness about legalization of safe abortion. Studying other fields than health and medicine [AOR 0.48; 95%CI (0.23, 0.85)], being the only child for their family [AOR 0.28; 95%CI (0.13, 0.86)], having no boy friend [AOR 0.34; 95%CI (0.12, 0.74)], using family planning [AOR 0.50; 95%CI (0.13 and 0.86)], being 25 years or older [AOR 1.64; 95%CI (1.33, 2.80)] were significantly associated with awareness

    The Korean Scale for Internet Addiction (K-Scale) was developed in Korea for assessing addictive internet behaviors. This study aims to adopt K-Scale and examine its psychometric properties in Japanese adolescents. In 2014, 589 (36.0% boys) high school students (Grade 10-12) from Japan completed a survey, including items of Japanese versions of K-Scale and Smartphone Scale for Smartphone Addiction (S-Scale). Model fit indices of the original four-factor structure, three-factor structure obtained from exploratory factor analysis, and improved two-factor structure of K-Scale were computed using confirmatory factor analysis, with internal reliability of included items reported. The convergent validity of K-Scale was tested against self-rated internet addiction, and S-Scale using multiple regression models. The results showed that a second-order two-factor 13-item structure was the most parsimonious model (NFI=0.919, NNFI=0.935, CFI=0.949, and RMSEA=0.05) with good internal reliability (Cronbach's alpha=0.87). The two factors revealed were "Disturbance of Adaptation and Life Orientation" and "Withdrawal and Tolerance". Moreover, the correlation between internet user classifications defined by K-Scale and self-rating was significant. K-Scale total score was significantly and positively associated with S-Scale total (adjusted R 2 =0.440) and subscale scores (adjusted R 2 =0.439). In conclusion, K-Scale is a valid and reliable assessment scale of internet addiction for Japanese high school students after modifications. Copyright © 2017. Published by Elsevier B.V.

    Full Text Available The childhood epilepsy is a chronic disease that can have an impact in various spheres of life of the child, including academic performance and school attendance. This study aimed to describe and compare the school attendance of children with epilepsy who attend mainstream and special schools. Participants were 56 children aged between 7 and 14 years who attended regular or special schools located in two Brazilian cities of medium size. To collect the information we used two instruments: Data sheet of identification and characterization of the child and Data sheet to record the attendance school. The results showed that children in special schools had higher rates of absenteeism compared to students in regular schools. Additionally, we observed that these children use more drugs and have implications on health more severe than children in regular schools. Thus, it is the childhood epilepsy as a disease complex that brings substantial effects on various areas of children’s lives by reinforcing the need for studies that might expand the knowledge to and the experiences associated with the education of these children.

    The structure of hexadeca-mu-acetato-tetraaquadodeca-mu(3)-oxo-dodecamanganese bis(acetic acid) tetrahydrate, [Mn(12)O(12)(CH(3)COO)(16)(H(2)O)(4)] x 2CH(3)COOH x 4H(2)O, known as Mn(12)-acetate, has been determined at 83 (2) K by X-ray diffraction methods. The fourfold (S(4)) molecular symmetry is disrupted by a strong hydrogen-bonding interaction with the disordered acetic acid molecule of solvation, which displaces one of the acetate ligands in the cluster. Up to six Mn(12) isomers are potentially present in the crystal lattice, which differ in the number and arrangement of hydrogen-bonded acetic acid molecules. These results considerably improve the structural information available on this molecular nanomagnet, which was first synthesized and characterized by Lis [Acta Cryst. (1980), B36, 2042-2046].

    Objective The current study examined racial/ethnic differences in initial severity, session attendance, and counseling outcomes in a large and diverse sample of Asian American, Latino/a, and White student clients who utilized university counseling services between 2008 and 2012. Method We used archival data of 5,472 clients (62% female; M age = 23.1, SD = 4.3) who self-identified their race/ethnicity as being Asian American (38.9%), Latino/a (14.9%), or White (46.2%). Treatment engagement was measured by the number of counseling sessions attended; initial severity and treatment outcome were measured using the Outcome Questionnaire-45. Results Asian American clients, particularly Chinese, Filipino/a, Korean, and Vietnamese Americans, had greater initial severity compared to White clients. Asian Indian, Korean, and Vietnamese American clients used significantly fewer sessions of counseling than White clients after controlling for initial severity. All racial/ethnic minority groups continued to have clinically significant distress in certain areas (e.g., social role functioning) at counseling termination. Conclusions These findings highlight the need to devote greater attention to the counseling experiences of racial/ethnic minority clients, especially certain Asian American groups. Further research directions are provided. PMID:26390372

    Recovery high schools (RHSs) are an alternative high school option for adolescents with substance use disorders (SUDs), designed to provide a recovery-focused learning environment. The aims of this study were to examine the characteristics of youth who choose to attend RHSs, and to compare them with local and national comparison samples of youth in recovery from SUDs who were not enrolled in RHSs. We conducted secondary analysis of existing data to compare characteristics of youth in three samples: (1) adolescents with SUDs who enrolled in RHSs in Minnesota, Texas, and Wisconsin after discharge from treatment (RHSs; n = 171, 51% male, 86% White, 4% African American, 5% Hispanic); (2) a contemporaneously recruited local comparison sample of students with SUDs who did not enroll in RHSs (n = 123, 60% male, 77% White, 5% African American, 12% Hispanic); and (3) a national comparison sample of U.S. adolescents receiving SUD treatment (n = 12,967, 73% male, 37% White, 15% African American, 30% Hispanic). Students enrolled in RHSs had elevated levels of risk factors for substance use and relapse relative to both the local and national comparison samples. For instance, RHS students reported higher rates of pre-treatment drug use, past mental health treatment, and higher rates of post-treatment physical health problems than adolescents in the national comparison sample. We conclude that RHSs serve a population with greater co-occurring problem severity than the typical adolescent in SUD treatment; programming offered at RHSs should attend to these complex patterns of risk factors. SUD service delivery policy should consider RHSs as an intensive recovery support model for the most high-risk students with SUDs. Copyright © 2018 Elsevier Inc. All rights reserved.

    2017-10-01

    Full Text Available This paper examines the determinants of spending and the amount of time attending private supplementary tutoring, or commonly known as private tuition, in Malaysia. Based on 343 self-reported questionnaires with upper secondary students across three states in Malaysia and using multiple regression analysis, we identified ethnicity, father’s level of education and past academic performance as significant determinants of spending and amount of time attending private tuition. However, interestingly, we found that while geographical location and participation in internal tuition in schools were also determinants of spending, these two were not significant in determining the amount of time attending private supplementary tutoring. The identification of determinants of spending and amount of time, and in addition, the differences between these two illustrates the economic and educational dimensions of shadow education. More importantly, the insight also contributes to the formulation of possible interventions that can improve quality and reduce inequality in the mainstream education system.

    Glucose and creatinine are two of the most frequently measured substances in human blood/serum for assessing the health status of individuals. Because of their clinical significance, CCQM-K11 glucose in human serum and CCQM-K12 creatinine in human serum were the fourth and fifth key comparisons (KCs) performed by the Organic Analysis Working Group (OAWG). These KCs were conducted in parallel and were completed in 2001. The initial subsequent KCs for glucose, CCQM-K11.1, and creatinine, CCQM-K12.1, were completed in 2005. Measurements for the next KCs for these two measurands, CCQM-K11.2 and CCQM-K12.2, were completed in 2013. While designed as subsequent KCs, systematic discordances between the participants' and the anchor institution's results in both comparisons lead the OAWG to request reference results from two experienced laboratories that had participated in the 2001 comparisons. Based on the totality of the available information, the OAWG converted both CCQM-K11.2 and CCQM-K12.2 to 'Track C' KCs where the key comparison reference value is estimated by consensus. These comparisons highlighted that carrying out comparisons for complex chemical measurements and expecting to be able to treat them under the approaches used for formal CIPM subsequent comparisons is not an appropriate strategy. The approach used here is a compromise to gain the best value from the comparison; it is not an approach that will be used in the future. Instead, the OAWG will focus on Track A and Track C comparisons that are treated as stand-alone entities. Participation in CCQM-K11.2 demonstrates a laboratory's capabilities to measure a polar (pKow > 2), low molecular mass (100 g/mol to 500 g/mol) metabolite in human serum at relatively high concentrations (0.1 mg/g to 10 mg/g). Participation in CCQM-K12.2 demonstrates capabilities to measure similar classes of metabolites at relatively low concentrations (1 μg/g to 30 μg/g).

    K2 or "spice" has emerged as a popular legal alternative to marijuana among adolescents and young adults. However, no data has been published assessing prevalence of and associations with ever K2 use in any population. This study's aims were to examine prevalence of ever K2 use among a sample of college students, to determine characteristics of persons who use K2, and to access the association between K2 and other drug use. Ever use of K2 was reported by 69 (8%) of the sample of 852 college students. Response rate was 36%. Bivariate and multivariate analyses assessed whether sociodemographic characteristics and other drug use were associated with ever use of K2. Ever use of K2 was reported by 69 (8%) of the sample. Among these 69 individuals, 61 (88%) had used a cigarette and 25 (36%) had used a hookah to smoke K2. In multivariate analyses, K2 use was more common in males (vs. females, adjusted Odds Ratio (aOR)=2.0, 95% Confidence Interval (CI)=1.2-3.5, p=0.01) and 1st or 2nd year college students (vs. 3rd year or above, aOR=2.4, 95% CI=1.2-5.0, p=0.02). Ever use of K2 in this sample was higher than ever use of many other drugs of abuse that are commonly monitored in adolescents and young adults. Although DEA had banned five synthetic cannabinoids recently, clinicians and public health officials concerned with substance abuse in youth should be aware of and monitor the use of this drug in college students over time. © 2011 Hu et al; licensee BioMed Central Ltd.

    The world is at the dawn of a third industrial revolution, the digital revolution, that brings great changes the world over. Today, computing devices, the Internet, and the World Wide Web are vital technology tools that affect every aspect of everyday life and success. While computing technologies offer enormous benefits, there are equally enormous safety and security risks that have been growing exponentially since they became widely available to the public in 1994. Cybercriminals are increasingly implementing sophisticated and serious hack attacks and breaches upon our nation's government, financial institutions, organizations, communities, and private citizens. There is a great need for computer scientists to carry America's innovation and economic growth forward and for cybersecurity professionals to keep our nation safe from criminal hacking. In this digital age, computer science and cybersecurity are essential foundational ingredients of technological innovation, economic growth, and cybersecurity that span all industries. Yet, America's K-12 education institutions are not teaching the computer science and cybersecurity skills required to produce a technologically-savvy 21st century workforce. Education is the key to preparing students to enter the workforce and, therefore, American K-12 STEM education must be reformed to accommodate the teachings required in the digital age.

    Many adolescents do not reach the recommended levels of physical activity (PA), and students attending vocational studies are less committed to take part in physical education (PE) than other students. The purpose of the present study was twofold: 1) to examine differences in physical activity, diet, smoking habits, sleep and screen time among Norwegian vocational high school students who selected either a PE model focusing on PA skills, technique and improvement of physical performance ("Sports enjoyment") or more on health, play and having fun when participating in PE lessons ("Motion enjoyment"), and 2) to explore the students' experiences with PE programs. In this mixed methods study 181 out of 220 invited students (82%) comprising 141 (78%) girls and 40 (22%) boys attending vocational studies of Restaurant and Food Processing (24%), Design, Arts and Crafts (27%) or Healthcare, Childhood and Youth Development (49%) were recruited for participation in the new PE program. PA level, sedentary time and sleep were objectively recorded using the SenseWear Armband Mini. A self-report questionnaire was used to assess dietary habits, smoking and snuffing habits, use of alcohol, screen use and active transportation. Four focus group interviews with 23 students (12 boys) were conducted to explore how the students experienced the new PE program. Students attending "Motion enjoyment" accrued less steps/day compared to the "Sports enjoyment" group (6661 (5514, 7808) vs.9167 (7945, 10390) steps/day) and reported higher screen use (mean, 3.1; 95% CI, 2.8, 3.5) vs. 2.4 (2.0, 2.9) hours/day). Compared to those attending "Sports enjoyment", a higher number of students attending "Motion enjoyment" reported an irregular meal pattern (adjusted odds ratio, 5.40; 95% confidence interval (CI), 2.28, 12.78), and being a current smoker (12.22 (1.62, 107.95)). The students participating in the focus group interviews emphasized the importance of having competent and engaging teachers

  20. The Delicate Balance between Research, Teaching and Outreach: A Case Study of Physicists in K-12 Education

    Recent calls from a variety of sectors including some funding agencies and professional societies encourage physicists to take a more active interest in the education of K-12 students and their teachers. Although there are a broad range of possible activities, finding time to participate is always a challenge for the researcher. How does the busy physicist ensure that the time devoted to education or outreach activities produces meaningful results without adversely affecting his or her research program? Project Fulcrum, a NSF-funded program that teams science and math graduate students at the University of Nebraska-Lincoln with 4th -8th grade teachers in the Lincoln Public Schools, presents a case study of how research scientists can be meaningfully involved with K-12 education. Project Fulcrum's preliminary results indicate that the impact scientists have in the classroom goes far beyond providing expertise in physics, and turns out to be very different than originally anticipated. There are a wide variety of models for involvement in education and outreach that cover a broad span of time and energy commitments. Careful project choice, establishing administrative infrastructure, collaborating with other departments and colleges, and involving colleagues can optimize the impact-made-to-time-spent ratio. Challenges such as project evaluation, overcoming the negative attitudes of some physicists towards anything not related to research, and ensuring that participants get appropriate credit for their efforts will also be discussed. The conclusion will address the personal and professional rewards of involvement in education and outreach. This work is funded by the National Science Foundation (NSF-DGE0086358).

    The importance of active learning has continued to increase in Japan. The authors conducted classes for first-year students who entered the nursing program using the problem-based learning method which is a kind of active learning. Students discussed social topics in classes. The purposes of this study were to analyze the post-class essay, describe logical and critical thinking after attended a Problem-Based Learning (PBL) course. The authors used Mayring's methodology for qualitative content analysis and text mining. In the description about the skills required to resolve social issues, seven categories were extracted: (recognition of diverse social issues), (attitudes about resolving social issues), (discerning the root cause), (multi-lateral information processing skills), (making a path to resolve issues), (processivity in dealing with issues), and (reflecting). In the description about communication, five categories were extracted: (simple statement), (robust theories), (respecting the opponent), (communication skills), and (attractive presentations). As the result of text mining, the words extracted more than 100 times included "issue," "society," "resolve," "myself," "ability," "opinion," and "information." Education using PBL could be an effective means of improving skills that students described, and communication in general. Some students felt difficulty of communication resulting from characteristics of Japanese.

    Walking and biking to work, active commuting (AC) is associated with many health benefits, though rates of AC remain low in the US. K-12 educators represent a significant portion of the workforce, and employee health and associated costs may have significant economic impact. Therefore, the purpose of this study was to examine the current rates of AC and factors associated with AC among K-12 educators. A volunteer sample of K-12 educators (n = 437) was recruited to participate in an online survey. Participants responded about AC patterns and social ecological influences on AC (individual, interpersonal, institutional, community, and environmental factors). t-tests and ANOVAs examined trends in AC, and Pearson correlations examined the relationship between AC and dependent variables. Multiple regression analysis determined the relative influence of individual, interpersonal, institutional, community, and environmental levels on AC. Participants actively commuted 0.51 ± 1.93 times/week. There were several individual, interpersonal, institutional, community, and environmental factors significantly related to AC. The full model explained 60.8% of the variance in AC behavior. This study provides insight on the factors that determine K-12 educators mode of commute and provide some insight for employee wellness among this population.

    Since the properties of lead-free piezoelectric materials have thus far failed to meet those of lead-based materials, either chemical doping or morphological texturing should be employed to improve the piezoelectric properties of lead-free piezoelectric ceramics. The goal of this study was to synthesize plate-like K1/2Na1/2NbO3 and NaNbO3 particles, which are the most favorable templates for morphological texturing of K1/2Na1/2NbO3 ceramics. To achieve this goal, Bi2.5Na3.5Nb5O18 precursors in a plate-like shape were first synthesized and subsequently converted into K1/2Na1/2NbO3 or NaNbO3 particles that retain the morphology of Bi2.5Na3.5Nb5O18. In this study, we found that sodium or potassium carbonate does not play a major role in converting the Bi2.5Na3.5Nb5O18 precursor to K1/2Na1/2NbO3 or NaNbO3, on the contrary to previous reports; however, the salt contributes to the conversion reaction. All synthesis processes have been performed via a molten salt method, and scanning electron microscopy, scanning probe microscopy, and inductively coupled plasma mass spectroscopy were used to characterize the synthesized K1/2Na1/2NbO3 or NaNbO3 templates.

    2010-01-01

    K-12 educators need effective and relevant astronomy professional development. WISE Telescope (Wide-Field Infrared Survey Explorer) and Spitzer Space Telescope Education programs provided an immersive teacher professional development workshop at Arecibo Observatory in Puerto Rico during the summer of 2009. As many common misconceptions involve scale and distance, teachers worked with Moon/Earth scale, solar system scale, and distance of objects in the universe. Teachers built and used basic telescopes, learned about the history of telescopes, explored ground and satellite based telescopes, and explored and worked on models of WISE Telescope. An in-depth explanation of WISE and Spitzer telescopes gave participants background knowledge for infrared astronomy observations. We taught the electromagnetic spectrum through interactive stations. The stations included an overview via lecture and power point, the use of ultraviolet beads to determine ultraviolet exposure, the study of WISE lenticulars and diagramming of infrared data, listening to light by using speakers hooked up to photoreceptor cells, looking at visible light through diffraction glasses and diagramming the data, protocols for using astronomy based research in the classroom, and infrared thermometers to compare environmental conditions around the observatory. An overview of LIDAR physics was followed up by a simulated LIDAR mapping of the topography of Mars. We will outline specific steps for K-12 infrared astronomy professional development, provide data demonstrating the impact of the above professional development on educator understanding and classroom use, and detail future plans for additional K-12 professional development. Funding was provided by WISE Telescope, Spitzer Space Telescope, Starbucks, Arecibo Observatory, the American Institute of Aeronautics and Astronautics, and the Washington Space Grant Consortium.

    Educational researchers postulate that every individual has a different learning style. The aim of this descriptive study was to determine the learning styles of first-year medical students using the Turkish version of the visual, auditory, read-write, kinesthetic (VARK) questionnaire. This study was performed at the Department of Medical Education of Erciyes University in February 2006. The Turkish version of the VARK questionnaire was administered to first-year medical students to determine their preferred mode of learning. According to the VARK questionnaire, students were divided into five groups (visual learners, read-write learners, auditory learners, kinesthetic learners, and multimodal learners). The unimodality preference was 36.1% and multimodality was 63.9%. Among the students who participated in the study (155 students), 23.3% were kinesthetic, 7.7% were auditory, 3.2% were visual, and 1.9% were read-write learners. Some students preferred multiple modes: bimodal (30.3%), trimodal (20.7%), and quadmodal (12.9%). The learning styles did not differ between male and female students, and no statistically significant difference was determined between the first-semester grade average points and learning styles. Knowing that our students have different preferred learning modes will help the medical instructors in our faculty develop appropriate learning approaches and explore opportunities so that they will be able to make the educational experience more productive.

    The observation of ..lambda..-hypernuclear levels in /sub ..lambda..//sup 12/C by associated production through the (..pi../sup +/,K/sup +/) reaction is reported. Spectrometers used in the measurements are discussed. The /sub ..lambda..//sup 12/C excitation energy spectra were recorded at laboratory scattering angles of 5.6/sup 0/, 10.3/sup 0/, and 15.2/sup 0/. The spectra show two major peaks - one attributed to the ground state, and one about 11 MeV higher in excitation. The peak near 11 MeV excitation energy is believed to be almost entirely composed of a multiplet of three J/sup ..pi../ = 2/sup +/ states. Relativistic DWBA calculations imply support for the expectation that higher spin states are preferentially populated in the (..pi../sup +/,K/sup +/) reaction, compared to the (K/sup -/,..pi../sup -/) reaction in which lower spin states are excited. 29 refs., 40 figs.

    Full Text Available SDS, C12E8, CHAPS or CHAPSO or a combination of two of these detergents is generally used for the solubilization of Na,K-ATPase and other ATPases. Our method using only C12E8 has the advantage of considerable reduction of the time for enzyme purification, with rapid solubilization and purification in a single chromatographic step. Na,K-ATPase-rich membrane fragments of rabbit kidney outer medulla were obtained without adding SDS. Optimum conditions for solubilization were obtained at 4ºC after rapid mixing of 1 mg of membrane Na,K-ATPase with 1 mg of C12E8/ml, yielding 98% recovery of the activity. The solubilized enzyme was purified by gel filtration on a Sepharose 6B column at 4ºC. Non-denaturing PAGE revealed a single protein band with phosphomonohydrolase activity. The molecular mass of the purified enzyme estimated by gel filtration chromatography was 320 kDa. The optimum apparent pH obtained for the purified enzyme was 7.5 for both PNPP and ATP. The dependence of ATPase activity on ATP concentration showed high (K0.5 = 4.0 µM and low (K0.5 = 1.4 mM affinity sites for ATP, with negative cooperativity. Ouabain (5 mM, oligomycin (1 µg/ml and sodium vanadate (3 µM inhibited the ATPase activity of C12E8-solubilized and purified Na,K-ATPase by 99, 81 and 98.5%, respectively. We have shown that Na,K-ATPase solubilized only with C12E8 can be purified and retains its activity. The activity is consistent with the form of (alphaß2 association.

    Full Text Available Abstract Background With the backdrop of a global ecstasy epidemic, this study sought to examine the trend, correlates, and onset sequence of ecstasy use among adolescents in Taiwan, where a well-established gateway drug such as marijuana is much less popular. Methods A multistage probability survey of school-attending adolescents in grades 7, 9, 10, and 12, aged 11–19 years, was conducted in 2004, 2005, and 2006. A self-administered anonymous questionnaire elicited response rates ranging from 94.3% to 96.6%. The sample sizes were 18232 respondents in 2004, 17986 in 2005, and 17864 in 2006. Results In terms of lifetime prevalence and incidence, ecstasy and ketamine by and large appeared as the first and second commonly used illegal drugs, respectively, among middle (grades 7 and 9 and high school students (grades 10 and 12 during the 3-year survey period; however, this order was reversed in the middle school-aged students starting in 2006. Having sexual experience, tobacco use, and betel nut use were factors consistently associated with the onset of ecstasy use across years. The majority of ecstasy users had been involved in polydrug use, such as the use of ketamine (41.4%–53.5%, marijuana (12.7%–18.7%, and methamphetamine (4.2%–9.5%. Conclusion From 2004 to 2006, a decline was noted in the prevalence and incidence rate of ecstasy, a leading illegal drug used by school-attending adolescents in Taiwan since the early 2000s. The emerging ketamine use trend may warrant more attention in the future.

    2017-01-01

    Identifying the factors that determine academic performance is an essential part of educational research. Existing research indicates that class attendance is a useful predictor of subsequent course achievements. The majority of the literature is, however, based on surveys and self-reports, methods which have well-known systematic biases that lead to limitations on conclusions and generalizability as well as being costly to implement. Here we propose a novel method for measuring class attendance that overcomes these limitations by using location and bluetooth data collected from smartphone sensors. Based on measured attendance data of nearly 1,000 undergraduate students, we demonstrate that early and consistent class attendance strongly correlates with academic performance. In addition, our novel dataset allows us to determine that attendance among social peers was substantially correlated (>0.5), suggesting either an important peer effect or homophily with respect to attendance.

    Teachers and their K-12 students lack firsthand experience in science research and often harbor misconceptions about science practices and the nature of science. To address this challenge, the NOAA-funded Student-Teacher-Researcher (STAR) partnership that provides rural high school students with authentic research experiences investigating the amount and sources of nitrate in schoolyard runoff. Teachers received training, guiding curricular materials aligned with NGSS and in-classroom support. With a focus on evidence-based reasoning skills, students actively participate in the research process through sample collection, data analysis, and an in-person discussion of conclusions and implications with our scientist team. As a member of this team, I assisted with refining the study design, analyzing nitrate isotope runoff samples, and sharing insights and feedback with students during the in-person discussion session. Assessment results indicate student gained an understanding of nitrate pollution and of science practices. As a graduate student, young scientist, and possessor of a B.S. in Science Education, I already recognized the value of involving K-12 students and teachers in authentic research experiences, as these experiences expose students to the nature of science while also improving content knowledge. During the STAR partnership, I learned firsthand some of the obstacles presented during outreach involving partnerships between a research institution and schools, such as inflexibility of school scheduling and the need for flexibility with research questions requiring complex lab analysis. Additionally, I discovered the challenge of working systemically across a school district, which can have broad impact but limit student experiences. Highlights of my experience included interactions with students and teachers, especially when students have unexpected answers to my questions, providing novel explanations for patterns observed in the data.

    The World Wide Web can be a powerful tool for reaching the public as well as students and teachers around the world, supporting both formal and informal science education. The Windows to the Universe Project, initiated in 1995, provides a case study of approaches for the use of the web to support earth and space science education and literacy efforts. Through the use of innovative approaches such as easy to use design, multi-level content, and science concepts presented in a broader background context that includes connections to culture and the humanities, Windows to the Universe is an accessible format for individuals of various ages and learning styles. A large global audience regularly uses the web site to learn about earth and space science as well as related humanities content such as myths from around the world. User surveys show that the site has over 4 millions users per year, 65 percent of which are K-12 teachers and students. Approximately 46 percent of users access the site once per week or more. Recently, we have had the opportunity to expand our efforts while we continue to update existing content based on new scientific findings and events. Earth science content on Windows to the Universe is currently growing with a new geology section and development efforts are underway to expand our space weather content with a new curriculum. Educational games allow users to learn about space in a playful context, and an online journaling tool further integrates literacy into the learning experience. In addition, we are currently translating the entire Windows to the Universe web site into Spanish. We have included educators in the project as co-designers from its inception, and by aggressively utilizing and providing professional development opportunities for teachers, the web site is now used in thousands of classrooms around the world. In the past year we have continued to support K-12 educators by adding to our suite of classroom activities and leading

    2013-12-01

    Statistics indicate that most Americans learn what they will know about science within the confines of our public K-12 education system and the media. Next Generation Science Standards (NGSS) aim to remedy science illiteracy and provide guidelines to exceed the Common Core State Standards that most U.S. state governments have adopted, by integrating disciplinary cores with crosscutting ideas and real life practices. In this vein, we present a prototype ';Virtual Ice Sheet Laboratory' (I-Lab), geared to K-12 students, educators and interested members of the general public. I-Lab will allow users to perform experiments using a state-of-the-art dynamical ice sheet model and provide detailed downloadable lesson plans, which incorporate this model and are consistent with NGSS Physical Science criteria for different grade bands (K-2, 3-5, 6-8, and 9-12). The ultimate goal of this website is to improve public climate science literacy, especially in regards to the crucial role of the polar ice sheets in Earth's climate and sea level. The model used will be the Ice Sheet System Model (ISSM), an ice flow model developed at NASA's Jet Propulsion Laboratory and UC Irvine, that simulates the near-term evolution of polar ice sheets (Greenland and Antarctica) and includes high spatial resolution capabilities and data assimilation to produce realistic simulations of ice sheet dynamics at the continental scale. Open sourced since 2011, ISSM is used in cutting edge cryosphere research around the globe. Thru I-Lab, students will be able to access ISSM using a simple, online graphical interface that can be launched from a web browser on a computer, tablet or smart phone. The interface will allow users to select different climate conditions and watch how the polar ice sheets evolve in time under those conditions. Lesson contents will include links to background material and activities that teach observation recording, concept articulation, hypothesis formulation and testing, and

    The aim of this study is to determine the prevalence of low vision among students attending all the schools for the blind in Oyo State, Nigeria. The study set out to determine the proportion of students with low vision/severe visual impairment after best correction, to determine the causes of the low vision, to document the associated pathologies, to determine the types of treatment and visual aid devices required, and to provide the visual aids needed to the students in the schools. All schools students for the blind in Oyo State were evaluated between August 2007 and January 2008. All the students underwent a thorough ophthalmic examination that included measurement of visual acuity, retinoscopy and subjective refraction, tests for visual aids where indicated, and a structured questionnaire was administered. A total of 86 students were included in the study and the mean age was 19.4 ± 8.19 years. Twenty six (30%) were under 16 years of age. The most common cause of blindness was bilateral measles keratopathy/vitamin A deficiency (VAD) in 25 students (29.1%). The most common site affected was the cornea in 25 students (29.1%), the lens in 23 (26.7%), and the retina/optic nerve in 16 (18.6%). Preventable blindness was mainly from measles keratopathy/VAD (29.1%). Eleven students benefited from refraction and correction with visual aids; two having severe visual impairment (SVI), and nine having visual impairment (VI) after correction. The prevalence of low vision in the schools for the blind in Oyo State is 2.3%, while the prevalence of visual impairment is 10.5%. These results suggest that preventable and treatable ocular conditions are the source of significant childhood blindness in Oyo State.

    Full Text Available Aim of the study. To establish: 1 the amount of research on general motor fitness of 1st-year students, conducted at selected Polish institutions of higher education between 1953-2010; 2 the number and kind of motor tests applied in this kind of research as well as the frequency of these tests during the period under study. Material and methods: The material for this research was composed of the publications on motor fitness of the first-year students taking part in specific motor trials applied at Polish tertiary institutions between 1953 - 2010. A diagnostic poll method was used in the research. Results: Fifty-four original research cases conducted in the period under study were observed. Within this period the trials such as: “100m run”, “jump from the run-up”, “grenade throw” and “ shot put” were more popular during the earlier years, while the trials such us: “zig-zag run”, “standing long jump”, and “medicine ball throw” were characteristic of more recent studies. Some of the most popular motor trials were: “standing long jump” – 38 cases, “medicine ball throw” – 30 cases, “zig-zag run” – 28 cases, “shuttle runs” – 9 cases, "short distance runs” – 12 cases, “downward bend from standing position” – 10 cases, and "vertical jump” – 8 cases. Conclusions: 1. Little research concerning the level of physical fitness of first-year students attending Polish tertiary institutions was conducted in the years 1953-2010; 2. The amount of motor fitness research carried out during this period fails to provide constant systematic assessment of the state of the students’ physical condition, which is a result of too large dispersions in time and territory where the measurements were taken; 3. In the motor fitness tests conducted with 1st-year students the determining variable was mainly gender, and only few research cases were found in which general motor fitness was analyzed according to

    Despite the voluminous literature on the potentials of single-sex schools, there is no consensus on the effects of single-sex schools because of student selection of school types. We exploit a unique feature of schooling in Seoul—the random assignment of students into single-sex versus coeducational high schools—to assess causal effects of single-sex schools on college entrance exam scores and college attendance. Our validation of the random assignment shows comparable socioeconomic backgrounds and prior academic achievement of students attending single-sex schools and coeducational schools, which increases the credibility of our causal estimates of single-sex school effects. The three-level hierarchical model shows that attending all-boys schools or all-girls schools, rather than coeducational schools, is significantly associated with higher average scores on Korean and English test scores. Applying the school district fixed-effects models, we find that single-sex schools produce a higher percentage of graduates who attended four-year colleges and a lower percentage of graduates who attended two-year junior colleges than do coeducational schools. The positive effects of single-sex schools remain substantial, even after we take into account various school-level variables, such as teacher quality, the student-teacher ratio, the proportion of students receiving lunch support, and whether the schools are public or private.

    Despite the voluminous literature on the potentials of single-sex schools, there is no consensus on the effects of single-sex schools because of student selection of school types. We exploit a unique feature of schooling in Seoul-the random assignment of students into single-sex versus coeducational high schools-to assess causal effects of single-sex schools on college entrance exam scores and college attendance. Our validation of the random assignment shows comparable socioeconomic backgrounds and prior academic achievement of students attending single-sex schools and coeducational schools, which increases the credibility of our causal estimates of single-sex school effects. The three-level hierarchical model shows that attending all-boys schools or all-girls schools, rather than coeducational schools, is significantly associated with higher average scores on Korean and English test scores. Applying the school district fixed-effects models, we find that single-sex schools produce a higher percentage of graduates who attended four-year colleges and a lower percentage of graduates who attended two-year junior colleges than do coeducational schools. The positive effects of single-sex schools remain substantial, even after we take into account various school-level variables, such as teacher quality, the student-teacher ratio, the proportion of students receiving lunch support, and whether the schools are public or private.

    Making effective and efficient use of outreach resources can be difficult for student groups in smaller rural communities. Washington State University's OSA/SPIE student chapter desires well attended yet cost-effective ways to educate and inform the public. We designed outreach activities focused on three different funding levels: low upfront cost, moderate continuing costs, and high upfront cost with low continuing costs. By featuring our activities at well attended events, such as a pre-football game event, or by advertising a headlining activity, such as a laser maze, we take advantage of large crowds to create a relaxed learning atmosphere. Moreover, participants enjoy casual learning while waiting for a main event. Choosing a particular funding level and associating with well-attended events makes outreach easier. While there are still many challenges to outreach, such as motivating volunteers or designing outreach programs, we hope overcoming two large obstacles will lead to future outreach success.

    To better understand the molecular basis underlying aphid immune tolerance to beneficial bacteria and immune defense to pathogenic bacteria, we characterized how the pea aphid Acyrthosiphon pisum responds to Escherichia coli K-12 infections. E. coli bacteria, usually cleared in the hemolymph of other insect species, were capable of growing exponentially and killing aphids within a few days. Red fluorescence protein expressing E. coli K-12 laboratory strain multiplied in the aphid hemolymph as well as in the digestive tract, resulting in death of infected aphids. Selected gene deletion mutants of the E. coli K-12 predicted to have reduced virulence during systemic infections showed no difference in either replication or killing rate when compared to the wild type E. coli strain. Of note, however, the XL1-Blue E. coli K-12 strain exhibited a significant lag phase before multiplying and killing aphids. This bacterial strain has recently been shown to be more sensitive to oxidative stress than other E. coli K-12 strains, revealing a potential role for reactive oxygen species-mediated defenses in the otherwise reduced aphid immune system.

    K-Ras, a molecular switch that regulates cell growth, apoptosis and metabolism, is activated when it undergoes a conformation change upon binding GTP and is deactivated following the hydrolysis of GTP to GDP. Hydrolysis of GTP in water is accelerated by coordination to K-Ras, where GTP adopts a high-energy conformation approaching the transition state. The G12A mutation reduces intrinsic K-Ras GTP hydrolysis by an unexplained mechanism. Here, crystal structures of G12A K-Ras in complex with GDP, GTP, GTPγS and GppNHp, and of Q61A K-Ras in complex with GDP, are reported. In the G12A K-Ras–GTP complex, the switch I region undergoes a significant reorganization such that the Tyr32 side chain points towards the GTP-binding pocket and forms a hydrogen bond to the GTP γ-phosphate, effectively stabilizing GTP in its precatalytic state, increasing the activation energy required to reach the transition state and contributing to the reduced intrinsic GTPase activity of G12A K-Ras mutants.

    Much attention has been devoted in recent years to the importance of Science, Technology, Engineering, and Math (STEM) education in K-12 curriculum for developing a capable workforce. Equally important is the role of the voting public in understanding STEM-related issues that impact public policy debates such as the potential impacts of climate change, hydraulic fracturing in oil and gas exploration, mining impacts on water quality, and science funding. Since voted officials have a major impact on the future of these policies, it is imperative that the general public have an understanding of the basic science behind these issues. By engaging with the public in a more fundamental way, university students can play an important role in educating the public while at the same time enhancing their communication skills and gaining valuable teaching experience. I will talk about my own experiences in (1) evaluating and publishing water chemistry and hazardous waste cleanup curriculum on the K-12 engineering platform TeachEngineering.org, (2) organizing public tours of water and energy sites (e.g., abandoned mine sites, coal power plants, wastewater treatment plants, hazardous waste treatment facilities), and (3) other outreach and communication activities including public education of environmental issues through consultations with customers of a landscaping/lawn mowing company. The main focus of this presentation will be the role that graduate students can play in engaging and educating their local community and lessons learned from community projects (Dittrich, 2014; 2012; 2011).

    This technical feasibility study provides documentation and research results supporting a possible set of strategies to achieve source zero energy K-12 school buildings as defined by the U.S. Department of Energy (DOE) zero energy building (ZEB) definition (DOE 2015a). Under this definition, a ZEB is an energy-efficient building in which, on a source energy basis, the actual annual delivered energy is less than or equal to the on-site renewable exported energy.

  6. Using a Non-Equivalent Groups Quasi Experimental Design to Reduce Internal Validity Threats to Claims Made by Math and Science K-12 Teacher Recruitment Programs

    The American Recovery and Reinvestment Act national policy established in 2009 calls for ``meaningful data'' that demonstrate educational improvements, including the recruitment of high-quality teachers. The scant data available and the low credibility of many K-12 math/science teacher recruitment program evaluations remain the major barriers for the identification of effective recruitment strategies. Our study presents a methodology to better evaluate the impact of recruitment programs on increasing participants' interest in teaching careers. The research capitalizes on the use of several control groups and presents a non-equivalent groups quasi-experimental evaluation design that produces program effect claims with higher internal validity than claims generated by current program evaluations. With this method that compares responses to a teaching career interest question from undergraduates all along a continuum from just attending an information session to participating (or not) in the recruitment program, we were able to compare the effect of the program in increasing participants' interest in teaching careers versus the evolution of the same interest but in the absence of the program. We were also able to make suggestions for program improvement and further research. While our findings may not apply to other K-12 math/science teacher recruitment programs, we believe that our evaluation methodology does and will contribute to conduct stronger program evaluations. In so doing, our evaluation procedure may inform recruitment program designers and policy makers.

    To examine school- and student-level correlates of physical activity. Cross-sectional Year 2 data collected from 45 298 grade 9-12 students attending 89 secondary schools in the COMPASS study were examined using multi-level modelling to predict the likelihood of students a) achieving 60 minutes of moderate to vigorous physical activity (MVPA) daily; and b) achieving the Canadian Society for Exercise Physiology (CSEP) activity guideline for youth (60 minutes/MVPA daily, vigorous physical activity at least three days in a week, and resistance training at least three days in a week). The prevalence of students achieving 60 minutes of MVPA daily and meeting the CSEP guideline was 49.3% and 31.0% respectively. Modest between-school variability was identified (1.1% for 60 minutes MVPA and 0.8% for CSEP guideline). School-level characteristics significantly associated with the outcome measures included location, school size, quality of facilities, and accessibility of facilities. Significant student-level correlates included sex, grade, weekly income, binge drinking, fruit and vegetable consumption, and body mass index. Most youth in this large study reported inadequate physical activity levels. Students were more likely to achieve 60 minutes of MVPA if they attended a larger school or a school in an urban location, whereas students were less likely to meet the CSEP guideline if they attended a school in a small urban location. However, student-level factors, such as binge drinking and inadequate fruit and vegetable consumption, were more strongly associated with the outcomes examined.

    Full Text Available Abstract Background Substance use and poor dietary practices are prevalent among adolescents. The purpose of this study was to examine frequency of substance use and associations between cigarette, alcohol and marijuana use and selected dietary practices, such as sugar-sweetened beverages, high-fat foods, fruits and vegetables, and frequency of fast food restaurant use among alternative high school students. Associations between multi-substance use and the same dietary practices were also examined. Methods A convenience sample of adolescents (n = 145; 61% minority, 52% male attending six alternative high schools in the St Paul/Minneapolis metropolitan area completed baseline surveys. Students were participants in the Team COOL (Controlling Overweight and Obesity for Life pilot study, a group randomized obesity prevention pilot trial. Mixed model multivariate analyses procedures were used to assess associations of interest. Results Daily cigarette smoking was reported by 36% of students. Cigarette smoking was positively associated with consumption of regular soda (p = 0.019, high-fat foods (p = 0.037, and fast food restaurant use (p = 0.002. Alcohol (p = 0.005 and marijuana use (p = 0.035 were positively associated with high-fat food intake. With increasing numbers of substances, a positive trend was observed in high-fat food intake (p = 0.0003. There were no significant associations between substance use and fruit and vegetable intake. Conclusions Alternative high school students who use individual substances as well as multiple substances may be at high risk of unhealthful dietary practices. Comprehensive health interventions in alternative high schools have the potential of reducing health-compromising behaviors that are prevalent among this group of students. This study adds to the limited research examining substance use and diet among at-risk youth. Trial registration number ClinicalTrials.gov: NCT01315743

    Major part of recognising a person is face with the help of image processing techniques we can exploit the physical features of a person. In the old approach method that is used in schools and colleges it is there that the professor calls the student name and then the attendance for the students marked. Here in paper want to deviate from the old approach and go with the new approach by using techniques that are there in image processing. In this paper we presenting spontaneous presence for students in classroom. At first classroom image has been in use and after that image is kept in data record. For the images that are stored in the database we apply system algorithm which includes steps such as, histogram classification, noise removal, face detection and face recognition methods. So by using these steps we detect the faces and then compare it with the database. The attendance gets marked automatically if the system recognizes the faces.

    2018-01-01

    Depression may contribute to increased drinking in individuals with alcohol use disorder. Although Alcoholics Anonymous (AA) attendance predicts drinking reductions, there is conflicting information regarding the intermediary role played by reductions in depression. We explored whether AA attendance reduces depressive symptoms, the degree to which improvement in depression results in reductions in drinking, and in which subgroups these effects occur. 253 early AA affiliates (63% male) were recruited and assessed at baseline 3, 6, 9, 12, 18, and 24 months. Depression was measured using the Beck Depression Inventory (BDI) and was administered at baseline 3, 6, 12, 18, and 24 months. AA attendance and alcohol use outcomes were obtained with the Form 90. Mediation analyses were performed at early (3, 6, and 9 months) and late (12, 18, and 24 months) follow-up to investigate the degree to which reductions in depression mediated the effect of AA attendance on drinking, controlling for concurrent drinking. In addition, a series of moderated mediation analyses were performed using baseline depression severity as a moderator. At early follow-up, reductions in depression (6 months) mediated the effects of AA attendance (3 months) on later drinking (drinks per drinking day) (9 months) (b = -0.02, boot CI [-0.055, -0.0004]), controlling for drinking at 6 months. Baseline depression severity did not moderate the degree to which BDI mediated the effects of AA attendance on alcohol use (ps > .05). These findings provide further evidence that depression reduction is a mechanism by which AA attendance leads to reductions in alcohol use. Improving depression may help reduce alcohol use in individuals with AUD, and AA attendance may be an effective way to achieve that goal.

  15. 3-D Teaching of Climate Change: An innovative professional learning model for K-12 teachers

    2017-12-01

    In spite of the presumed controversy over the evidence for climate change, the recently released Next Generation Science Standards (NGSS) for K-12 include a focus on climate literacy and explicitly use the term `climate change.' In addition to the increased focus on climate change, the NGSS are also built upon a new three dimensional framework for teaching and learning science. Three dimensional learning has students engaging in scientific and engineering practices (Dimension 1), while using crosscutting concepts (Dimension 2) to explore and explain natural phenomena using disciplinary core ideas (Dimension 3). The adoption of these new standards in many states across the nation has created a critical need for on-going professional learning as in-service science educators begin to implement both climate change instruction and three dimensional teaching and learning in their classrooms. In response to this need, we developed an innovative professional learning model for preparing teachers to effectively integrate climate change into their new curriculum and engage students in three dimensional learning. Our professional learning model utilized ideas that have emerged from recent science education research and include: a) formative assessment probes for three dimensional learning that monitor students' progress; b) collaboration with scientists with expertise in climate science to understand the domain specific ways of doing science; and c) development of a community of practice for in-service teachers to provide feedback to each other on their implementation. In this poster presentation, we will provide details on the development of this professional learning model and discuss the affordances and challenges of implementing this type of professional learning experience.

    Arterial stiffness is associated with cardiovascular risk, morbidity, and mortality. The present paper reviews the main vitamins related to arterial stiffness and enabling destiffening, their mechanisms of action, providing a brief description of the latest studies in the area, and their implications for primary cardiovascular prevention, clinical practice, and therapy. Despite inconsistent evidence for destiffening induced by vitamin supplementation in several randomized clinical trials, positive results were obtained in specific populations. The main mechanisms are related to antiatherogenic effects, improvement of endothelial function (vitamins A, C, D, and E) and metabolic profile (vitamins A, B12, C, D, and K), inhibition of the renin-angiotensin-aldosterone system (vitamin D), anti-inflammatory (vitamins A, D, E, and K) and antioxidant effects (vitamins A, C, and E), decrease of homocysteine level (vitamin B12), and reversing calcification of arteries (vitamin K). Vitamins A, B12, C, D, E, and K status is important in evaluating cardiovascular risk, and vitamin supplementation may be an effective, individualized, and inexpensive destiffening therapy.

    2009-01-01

    Full Text Available Abstract Background General Practitioners spend a disproportionate amount of time on frequent attenders. So far, trials on the effect of interventions on frequent attenders have shown negative results. However, these trials were conducted in short-term frequent attenders. It would be more reasonable to target intervention at persistent frequent attenders. Typical characteristics of persistent frequent attenders, as opposed to 1-year frequent attenders and non-frequent attenders, may generate hypotheses regarding modifiable factors on which new randomized trials may be designed. Methods We used the data of all 28,860 adult patients from 5 primary healthcare centers. Frequent attenders were patients whose attendance rate ranked in the (age and sex adjusted top 10 percent during 1 year (1-year frequent attenders or 3 years (persistent frequent attenders. All other patients on the register over the 3-year period were referred to as non-frequent attenders. The lists of medical problems coded by the GP using the International Classification of Primary Care (ICPC were used to assess morbidity. First, we determined which proportion of 1-year frequent attenders was still a frequent attender during the next two consecutive years and calculated the GPs' workload for these patients. Second, we compared morbidity and number of prescriptions for non-frequent attenders, 1-year frequent attenders and persistent frequent attenders. Results Of all 1-year frequent attenders, 15.4% became a persistent frequent attender equal to 1.6% of all patients. The 1-year frequent attenders (3,045; 10.6% were responsible for 39% of the face-to-face consultations; the 470 patients who would become persistent frequent attenders (1.6% were responsible for 8% of all consultations in 2003. Persistent frequent attenders presented more social problems, more psychiatric problems and medically unexplained physical symptoms, but also more chronic somatic diseases (especially diabetes

    Comprehensive experimental resources, such as ORFeome clone libraries and deletion mutant collections, are fundamental tools for elucidation of gene function. Data sets by omics analysis using these resources provide key information for functional analysis, modeling and simulation both in individual and systematic approaches. With the long-term goal of complete understanding of a cell, we have over the past decade created a variety of clone and mutant sets for functional genomics studies of Escherichia coli K-12. We have made these experimental resources freely available to the academic community worldwide. Accordingly, these resources have now been used in numerous investigations of a multitude of cell processes. Quality control is extremely important for evaluating results generated by these resources. Because the annotation has been changed since 2005, which we originally used for the construction, we have updated these genomic resources accordingly. Here, we describe GenoBase (http://ecoli.naist.jp/GB/), which contains key information about comprehensive experimental resources of E. coli K-12, their quality control and several omics data sets generated using these resources. © The Author(s) 2014.

  20. Chlamydia trachomatis infection and sexual behaviour among female students attending higher education in the Republic of Ireland.

    LENUS (Irish Health Repository)

    O'Connell, Emer

    2009-10-29

    BACKGROUND: There are no prevalence data on Chlamydia trachomatis relating to female students attending higher education available for the Republic of Ireland. This information is required to guide on the necessity for Chlamydia screening programmes in higher education settings. This research aimed to determine the prevalence of and predictive risk factors for Chlamydia trachomatis genital infection among female higher education students in Ireland. METHODS: All females presenting during one-day periods at Student Health Units in three higher education institutions in two cities in the Republic of Ireland were invited to participate. Participants completed a questionnaire on lifestyle and socio-demographic factors and provided a urine sample. Samples were tested for C. trachomatis DNA by a PCR based technique (Cobas Amplicor, Roche). To examine possible associations between a positive test and demographic and lifestyle risk factors, a univariate analysis was performed. All associations with a p value < 0.05 were included in a multivariate logistic regression analysis. RESULTS: Of the 460 sexually active participants 22 tested positive (prevalence 4.8%; 95% CI 3.0 to 7.1%). Variables associated with significantly increased risk were current suggestive symptoms, two or more one-night stands and three or more lifetime sexual partners. The students displayed high-risk sexual behaviour. CONCLUSION: The prevalence of C. trachomatis infection and the lack of awareness of the significance of suggestive symptoms among sexually experienced female students demonstrate the need for a programme to test asymptomatic or non-presenting higher education students. The risk factors identified by multivariate analysis may be useful in identifying those who are most likely to benefit from screening. Alcohol abuse, condom use, sexual behaviour (at home and abroad) and, knowledge of sexually transmitted infections (STIs) (including asymptomatic nature or relevant symptoms) were
