Inquiry based learning with a virtual microscope  

Science.gov (United States)

As part of newly funded initiative, the Wolfson OpenScience Laboratory, we are linking a tool for inquiry based learning, nQuire (http://www.nquire.org.uk) with the virtual microscope for Earth science (http://www.virtualmicroscope.co.uk) to allow students to undertake projects and gain from inquiry based study thin sections of rocks without the need for a laboratory with expensive petrological microscopes. The Virtual Microscope (VM) was developed for undergraduate teaching of petrology and geoscience, allowing students to explore rock hand specimens and thin sections in a browser window. The system is based on HTML5 application and allows students to scan and zoom the rocks in a browser window, view in ppl and xpl conditions, and rotate specific areas to view birefringence and pleochroism. Importantly the VM allows students to gain access to rare specimens such as Moon rocks that might be too precious to suffer loss or damage. Experimentation with such specimens can inspire the learners' interest in science and allows them to investigate relevant science questions. Yet it is challenging for learners to engage in scientific processes, as they may lack scientific investigation skills or have problems in planning their activities; for teachers, managing inquiry activities is a demanding task (Quintana et al., 2004). To facilitate the realization of inquiry activities, the VM is being integrated with the nQuire tool. nQuire is a web tool that guides and supports students through the inquiry process (Mulholland et al., 2011). Learners are encouraged to construct their own personally relevant hypothesis, pose scientific questions, and plan the method to answer them. Then, the system enables users to collect and analyze data, and share their conclusions. Teachers can monitor their students' progress through inquiries, and give them access to new parts of inquiries as they advance. By means of the integration of nQuire and the VM, inquiries that involve collecting data through a microscope can be created and supported. To illustrate the possibilities of these tools, we have designed two inquiries that engage learners in the study of Moon rock samples under the microscope, starting from general questions such as comparison of Moon rocks or determining the origin of meteorites. One is aimed at undergraduate Geology students; the second has been conceived for the general public. Science teachers can reuse these inquiries, adapt them as they need, or create completely new inquiries using nQuire's authoring tool. We will report progress and demonstrate the combination of these two on-line tools to create an open educational resource allowing educators to design and run science inquiries for Earth and planetary science in a range of settings from schools to universities.

NGSS and Inquiry-Based Learning with The GLOBE Program  

Science.gov (United States)

The GLOBE Program (www.globe.gov) engages K-12 students through scientific discovery to learn about the Earth as a system and provides a curricular example for the Next Generation Science Standards (NGSS). A key component of GLOBE is its inquiry-based, hands-on activities, which align with the eight practices found in Dimension 1 of the Standards. GLOBE teachers currently address the crosscutting concepts from Dimension 2 in the Standards by engaging students in data analysis and application through GLOBE Investigations, such as GPS, hydrology and atmosphere. Hands-on activities align to the disciplinary core ideas of Dimension 3 of the Standards through the implementation of protocols in air, water, soil, land cover, and seasons in over 25,000 schools in more than 110 countries worldwide. Integration of technology, engineering, and the application of science have played a central role in The GLOBE Program since its inception in 1995. The GLOBE Program provides a venue for students to report their own scientific investigations to scientists, teachers, and other students through student research reports, as well as a variety of student conference opportunities. This presentation will provide samples of how The GLOBE Program and GLOBE teachers encourage inquiry-based learning for student achievement of the NGSS through the review of student reports. These reports serve as artifacts illustrating the scientific practices, crosscutting concepts, and disciplinary core ideas students engage in while participating in GLOBE. This review will illustrate the extent to which GLOBE protocols and activities support NGSS, indicate gaps or mismatches in scope and sequence, provide recommendations for new materials development, and demonstrate a process that can be repeated by other science education programs to review their own current alignment to NGSS.

Supporting Students’ Interest through Inquiry-Based Learning in the Context of Fuel Cells  

Directory of Open Access Journals (Sweden)

Full Text Available The main aim of this research is to understand how inquiry-based learning in the context of fuel cells support the interest of 14 to 15-year-old male and female junior high school students. In total, 18 student groups (N=159 were involved in the case study in which a learning material with inquiry-based laboratory work in the context of fuel cells, designed based on previous research, was used. According to the survey conducted as a part of this research, the majority of youth liked inquiry-based chemistry experiments. The tangible stages of the work, i.e. compiling the miniature fuel cell car and operating it in practice, interested the youth the most. Boys were significantly more interested than girls in the applications of fuel cells related to the studied subject. Girls were interested in hydrogen energy economy, and that the issue is topical at the moment. Girls were also significantly more interested in the stages of inquiry-based learning – reporting the results and answering the questions that required reasoning. It seems that the model of inquiry-based learning used here and the learning materials give good opportunities for increasing the interests in chemistry among girls and boys alike, and thus provide a solution for the biggest challenge in chemistry education – increasing the youth’s interest in chemistry.

Teaching numerical methods with IPython notebooks and inquiry-based learning  

KAUST Repository

A course in numerical methods should teach both the mathematical theory of numerical analysis and the craft of implementing numerical algorithms. The IPython notebook provides a single medium in which mathematics, explanations, executable code, and visualizations can be combined, and with which the student can interact in order to learn both the theory and the craft of numerical methods. The use of notebooks also lends itself naturally to inquiry-based learning methods. I discuss the motivation and practice of teaching a course based on the use of IPython notebooks and inquiry-based learning, including some specific practical aspects. The discussion is based on my experience teaching a Masters-level course in numerical analysis at King Abdullah University of Science and Technology (KAUST), but is intended to be useful for those who teach at other levels or in industry.

Blended learning in dentistry: 3-D resources for inquiry-based learning  

Directory of Open Access Journals (Sweden)

Full Text Available Motivation is an important factor for inquiry-based learning, so creative design of learning resources and materials is critical to enhance students’ motivation and hence their cognition. Modern dentistry is moving towards “electronic patient records” for both clinical treatment and teaching. Study models have long been an essential part of dental records. Traditional plaster casts are, however, among the last type of clinical record in the dental field to be converted into digital media as virtual models. Advantages of virtual models include: simpler storage; reduced risk of damage, disappearance, or misplacement; simpler and effective measuring; and easy transferal to colleagues. In order to support student engagement with the rapidly changing world of digital dentistry, and in order to stimulate the students’ motivation and depth of inquiry, this project aims to introduce virtual models into a Bachelor and Dental Surgery (BDS curriculum. Under a “blended” e-learning philosophy, students are first introduced to the new software then 3-D models are incorporated into inquiry-based problems as stimulus materials. Face-to-face tutorials blend virtual model access via interactive whiteboards (IWBs. Students’ perceptions of virtual models including motivation and cognition as well as the virtual models’ functionality were rated after a workshop introducing virtual models and plaster models in parallel. Initial student feedback indicates that the 3-D models have been generally well accepted, which confirmed the functionality of the programme and the positive perception of virtual models for enhancing students’ learning motivation. Further investigation will be carried out to assess the impact of virtual models on students’ learning outcomes.

Enhancing Students' Scientific and Quantitative Literacies through an Inquiry-Based Learning Project on Climate Change  

Directory of Open Access Journals (Sweden)

Full Text Available Promoting sustainability and dealing with complex environmental problems like climate change demand a citizenry with considerable scientific and quantitative literacy. In particular, students in the STEM disciplines of (biophysical science, technology, engineering, and mathematics need to develop interdisciplinary skills that help them understand the social dynamics of environmental problems and solutions. To this end, this study examines how participation in a semester-long inquiry-based learning project that involves sociological research on climate change beliefs, attitudes, and behaviors enhances the scientific and quantitative literacies of STEM students. The results suggest that participation in a sociological inquiry-based learning project helps STEM students to (a improve their knowledge of scientific and statistical principles and processes, (b hone their scientific research skills, and (c gain respect for sociology specifically and social science more generally. While the inquiry-based learning project described here deals with climate change, educators can adapt it to deal with other environmental social science research topics (e.g., water use, energy conservation, food security, sustainability.

Assessing the Effectiveness of Inquiry-based Learning Techniques Implemented in Large Classroom Settings  

Science.gov (United States)

Geoscience and education faculty at The University of Akron jointly developed a series of inquiry-based learning modules aimed at both non-major and major student populations enrolled in introductory geology courses. These courses typically serve 2500 students per year in four to six classes of 40-160 students each per section. Twelve modules were developed that contained common topics and assessments appropriate to Earth Science, Environmental Geology and Physical Geology classes. All modules were designed to meet four primary learning objectives agreed upon by Department of Geology faculty. These major objectives include: 1) Improvement of student understanding of the scientific method; 2) Incorporation of problem solving strategies involving analysis, synthesis, and interpretation; 3) Development of the ability to distinguish between inferences, data and observations; and 4) Obtaining an understanding of basic processes that operate on Earth. Additional objectives that may be addressed by selected modules include: 1) The societal relevance of science; 2) Use and interpretation of quantitative data to better understand the Earth; 3) Development of the students' ability to communicate scientific results; 4) Distinguishing differences between science, religion and pseudo-science; 5) Evaluation of scientific information found in the mass media; and 6) Building interpersonal relationships through in-class group work. Student pre- and post-instruction progress was evaluated by administering a test of logical thinking, an attitude toward science survey, and formative evaluations. Scores from the logical thinking instrument were used to form balanced four-person working groups based on the students' incoming cognitive level. Groups were required to complete a series of activities and/or exercises that targeted different cognitive domains based upon Bloom's taxonomy (knowledge, comprehension, application, analysis, synthesis and evaluation of information). Daily assessments of knowledge-level learning included evaluations of student responses to pre- and post-instruction conceptual test questions, short group exercises and content-oriented exam questions. Higher level thinking skills were assessed when students completed exercises that required the completion of Venn diagrams, concept maps and/or evaluation rubrics both during class periods and on exams. Initial results indicate that these techniques improved student attendance significantly and improved overall retention in the course by 8-14% over traditional lecture formats. Student scores on multiple choice exam questions were slightly higher (1-3%) for students taught in the active learning environment and short answer questions showed larger gains (7%) over students' scores in a more traditional class structure.

The design, enactment, and impact of an undergraduate, inquiry-based, astronomy laboratory learning environment  

Science.gov (United States)

This study investigated the design, enactment, and impact of an undergraduate, inquiry-based astronomy laboratory learning environment. The professor, Richard, adopted laboratory materials from the Center for Astronomy and Physics Education Research [CAPER] which were described by the group as inquiry-based. Students worked through these laboratory materials under the supervision of teaching assistants [TAs], and Richard led weekly TA meetings to monitor and instruct the TAs on his expectations. This study suggests that Richard was unsure of laboratory materials' learning goals and had received limited guidance on how to use and implement CAPER's materials. TAs also received limited guidance on how to interact with their students while they worked through the laboratory materials. TAs gave introductions during laboratory sessions that were similar to Richard's introductions given during weekly TA meetings. Data from this study suggests that most students were able to easily complete the laboratory materials without the assistance of their TA. When students did ask questions, questions were focused on obtaining the correct answer which TAs normally supplied though direct responses or questioning. This laboratory learning environment was found to have no impact on students' understanding of the nature of scientific inquiry, as measured by VOSI, which contradicts previous research findings associated with the materials. I suggest that professors should be cautious when adopting curriculum materials. Curriculum designers should provide information related to the design of their materials, the learning goals of those materials, sample student responses, and effective implementation strategies.

In particular, CILASS promotes approaches to IBL that involve students in collaborative discipline-based and inter-disciplinary inquiries, develop their information literacy capabilities, and use information and communications technologies imaginatively to enhance the learning experience.In order to provide suitable spaces for students and staff undertaking IBL, CILASS is establishing new learning and teaching spaces within its hub in the University’s new Information Commons (Centre for Learning Resources, which is scheduled to open in 2006-7. These spaces are being purpose-built to support collaborative IBL in an information- and technology-rich environment, and will offer flexibility in terms of configuring space differently for different learning activities combined with access to a range of advanced learning technologies. Additional funding for capital investment awarded to CILASS in January 2006 will allow for the creation of a further CILASS learning and teaching ‘collaboratory’ in a central satellite location within the University.This paper focuses in particular on the strategic approach being taken by CILASS to promoting the development of information literacy within the context of IBL.

Hidden in Plain Sight: Pre-Service Teachers’ Orientations Toward Inquiry-Based Learning in History  

Directory of Open Access Journals (Sweden)

Full Text Available In order to implement models of reform-based history education in the classroom there is a fundamental need to address preservice and practicing teachers’ understanding of learning and teaching history, mindful of the role inquiry must play in the process. The project described in this paper employed a comparative case design to explore how prospective social studies educators perceived inquiry-based instruction and the extent to which it aligned with relevant history education for middle and secondary students. Results suggest that the process undertaken by the independent inquiry group may have an implicit impact on shaping how preservice teachers understand inquiry. Yet these preservice teachers included more inquiry-based activities in lesson plan products analyzed as part of this project. After the implementation of both means of learning about historical inquiry, many remained conflicted about what the ideal model of inquiry represents for student learning and at what ability level students are capable of engaging in inquiry in social studies.

Implementing and Assessing Inquiry-Based Learning through the CAREER Award  

Science.gov (United States)

In order to fully attain the benefits of inquiry-based learning, instructors who typically employ the traditional lecture format need to make many adjustments to their approach. This change in styles can be intimidating and logistically difficult to overcome, both for instructors and students, such that a stepwise approach to this transformation is likely to be more manageable. In this session, I will describe a series of tools to promote inquiry-based learning that I am helping to implement and assess in classroom courses and student research projects. I will demonstrate the importance of integrating with existing institutional initiatives as well as recognizing how student development plays a key role in student engagement. Some of the features I will highlight include: defining both student learning outcomes and student development outcomes, converting content training to be self-directed and asynchronous, utilizing conceptests to help students practice thinking like scientists, and employing both objective pre/post assessment and student self-reflective assessment. Lastly, I will reflect on how the well-defined goal of teaching and research integration in the CAREER award solicitation resonated with me even as an undergraduate and helped inspire my early career.

Scientific evaluation of an intra-curricular educational kit to foster inquiry-based learning (IBL)  

Science.gov (United States)

Society becomes increasingly dependent on photonics technologies; however there is an alarming lack of technological awareness among secondary school students. They associate photonics with experiments and components in the class room that seem to bear little relevance to their daily life. The Rocard Report [5] highlights the need for fostering students' scientific skills and technological awareness and identifies inquiry based learning (IBL) as a means to achieve this. Students need to actively do science rather than be silent spectators. The `Photonics Explorer' kit was developed as an EU funded project to equip teachers, free-of-charge, with educational material designed to excite, engage and educate European secondary school students using guided inquiry based learning techniques. Students put together their own experiments using up-to-date versatile components, critically interpret results and relate the conclusions to relevant applications in their daily life. They work hands-on with the material, thus developing and honing their scientific and analytical skills that are otherwise latent in a typical class room situation. A qualitative and quantitative study of the impact of the kit in the classroom was undertaken with 50 kits tested in 7 EU countries with over 1500 students in the local language. This paper reports on the results of the EU wide field tests that show the positive impact of the kit in raising the self-efficacy, scientific skills and interest in science among students and the effectiveness of the kit in implementing IBL strategies in classrooms across EU.

An Open Educational Resource Supports a Diversity of Inquiry-Based Learning  

Directory of Open Access Journals (Sweden)

Full Text Available There have been numerous calls for research that demonstrates how open education resources (OERs are actually being used. This case study sought to shed light on the users of a well-visited set of modular music-education materials published at Connexions. Respondents to a voluntary survey included teachers, students, self-directed learners, music ensemble participants, and casual learners. Most reported accessing individual modules on their own initiative, as part of a specific, immediate inquiry, rather than responding to institutional directives or following entire online courses. This was supported by computer-log records, which showed that most visitors to a module arrived from an Internet search for terms specific to that module. The study suggests that, for teachers and students as well as self-directed learners, one function of OERs is as a resource for just-in-time, inquiry-based learning.

Teaching optics with an intra-curricular kit designed for inquiry-based learning  

Science.gov (United States)

In order to increase scientific literacy and the knowledge of science and technology of Europe's citizens, the European Commission suggests a more student-centred implementation of natural sciences in education systems. Inquiry-based learning (IBL) is not only an accepted method to promote students' interest and motivation, it also helps students learn the scientific method and fosters their research skills. However, IBL is rarely used in European classrooms. The main reason is that due to the strict curricula teachers do not have the time for preparation and they do not feel well equipped and trained in the use of IBL methods in class. The Photonics Explorer programme addresses these problems on the European level. Within the programme, a pan-European collaboration of professors, teachers and photonics experts have developed the Photonics Explorer kit for the teaching of optics and light-related topics in physics across various European secondary school curricula. It is designed for intra-curricular use and contains specially designed, hands-on experimental components, worksheets based on guided IBL and multimedia material. Additionally, the kit provides a teacher guide with a suggested lesson outline and sufficient background information for each topic.

Inquiry-Based Learning in an Intermediate-Level Undergraduate Neotectonics Course  

Science.gov (United States)

Integrating student-conducted research into the curriculum can provide students with many educational benefits. Documented benefits include, among others, increased communication skills, the ability to work as part of a research team, and enhanced self-confidence in individual problem-solving skills (e.g., Kardash, J. Ed. Psych., 2000; Seymour, et al., Science Education, 2004). As part of a larger departmental goal of integrating student- conducted research into all levels of the Pomona College Geology Department curriculum (e.g., Reinen, et al., CUR-Q, 2006), I have recently developed an intermediate-level Neotectonics course with a strong component of inquiry-based learning. This course was offered for the first time during the spring semester 2007, and will continue to be offered each year. In a series of guided inquiries throughout the course, students investigate recent seismicity and tectonic geomorphology in Southern California. With each subsequent assignment, student contributions to the research direction increases (e.g., data used, area studied, question addressed, methods used), culminating in team proposals and research projects investigating specific student-generated questions of regional tectonics. Students collect data for these investigations from several sources: (1) databases available online (e.g., IRIS, Harvard earthquake catalog), (2) desktop experiments (e.g., the "earthquake machine"), (3) topographic maps, and (4) field observations. The objective of this paper is to present initial results from this teaching experiment and examples of the projects which have been executed, including the preparation students received to be able to use the available data. Discussion and suggestions (particularly about effective means of conducting a rigorous long-term assessment) are strongly encouraged.

The AIA Solar Learning Center: Taking Inquiry-based EPO Online  

Science.gov (United States)

The observations of the Atmospheric Imaging Assembly aboard the Solar Dynamics Observatory (SDO-AIA) are expected to be groundbreaking within the field of heliophysics. To properly promote and explain the data produced by AIA, it is important that an innovative EPO effort be put forth. This has led to the development of "The AIA Solar Learning Center” (SLC), an inquiry-based educational website geared towards teaching about AIA and the Sun in general. The goal of the SLC is to provide K-12 students, teachers, parents, and homeschoolers with information and education about the Sun, primarily through hands-on activity modules that explain different aspects of our nearest star and the methods of observing it. While each module ultimately aims to impart information about the Sun or some related physical process, the activities also range across a host of different disciplines, including geology, chemistry, history, music, and art. In order to make the content applicable and accessible, activities are tailored to multiple difficulty levels, catering to different age groups. There is also a strong push towards facilitating teachers; activities are designed to fulfill specific teaching standards, and a host of additional teaching material is provided, including lesson plans and powerpoint presentations. Ultimately, the SLC aims to make science and the Sun inviting and accessible. The "Meet the Scientists” page will provide pictures and personal bios of participating scientists. Students will have the opportunity to interactively ask solar-related questions. There is even a host of lighter fare, such as a solar music playlist and links to relevant Facebook pages.

Evaluation of a High School Fair Program for Promoting Successful Inquiry-based Learning  

Science.gov (United States)

The success of inquiry-based learning (IBL) in supporting science literacy can be challenged when students encounter obstacles in the absence of proper support. This research is intended to evaluate the effectiveness of an Oregon public school district's regional science fair coaching program in promoting inquiry skills and positive attitudes toward science in participating high school students. The purpose of this study was to better understand students' perception of program support, obstacles or barriers faced by students, and potential benefits of IBL facilitated by the science fair program. Data included responses to informal and semi-structured interviews, an anonymous survey, a Skills assessment of final project displays, and an in-depth case study on three students' experiences. Results suggest that the science fair program can properly engage participants in authentic IBL. However, when assessing the participant's final project displays, I found that previous fair experience did not significantly increase mean scores as identified by the official Oregon Department of Education (ODE) scoring guides. Based on results from the case study, it is suggested that participants' low science self-concept, poor understanding of inquiry skills, and inability to engage in reflective discourse may reduce students' abilities to truly benefit. Recommendations to address this discrepancy include identifying specific needs of students through a pre--fair survey to develop more targeted support, and providing new opportunities to develop skills associated with science-self concept, understanding of inquiry and reflective discourse. In addition, results suggest that students would benefit from more financial support in the form of grants, and more connections with knowledgeable mentors.

The effect of guided inquiry-based instruction in secondary science for students with learning disabilities  

Science.gov (United States)

Students with learning disabilities (SWLDs) need to attain academic rigor to graduate from high school and college, as well as achieve success in life. Constructivist theories suggest that guided inquiry may provide the impetus for their success, yet little research has been done to support this premise. This study was designed to fill that gap. This quasi-experimental study compared didactic and guided inquiry-based teaching of science concepts to secondary SWLDs in SDC science classes. The study examined 38 students in four classes at two diverse, urban high schools. Participants were taught two science concepts using both teaching methods and posttested after each using paper-and-pencil tests and performance tasks. Data were compared to determine increases in conceptual understanding by teaching method, order of teaching method, and exposure one or both teaching methods. A survey examined participants' perceived self-efficacy under each method. Also, qualitative comparison of the two test formats examined appropriate use with SWLDs. Results showed significantly higher scores after the guided inquiry method on concept of volume, suggesting that guided inquiry does improve conceptual understanding over didactic instruction in some cases. Didactic teaching followed by guided inquiry resulted in higher scores than the reverse order, indicating that SWLDs may require direct instruction in basic facts and procedures related to a topic prior to engaging in guided inquiry. Also application of both teaching methods resulted in significantly higher scores than a single method on the concept of density, suggesting that SWLDs may require more in depth instruction found using both methods. No differences in perceived self-efficacy were shown. Qualitative analysis both assessments and participants' behaviors during testing support the use of performance tasks over paper-and-pencil tests with SWLDs. Implications for education include the use of guided inquiry to increase SWLDs conceptual understanding and process skills, while improving motivation and participation through hands-on learning. In addition, teachers may use performance tasks to better assess students' thought process, problem solving skills, and conceptual understanding. However, constructivist teaching methods require extra training, pedagogical skills, subject matter knowledge, physical resources, and support from all stakeholders.

The Integration of Creative Drama in an Inquiry-Based Elementary Program: The Effect on Student Attitude and Conceptual Learning  

Science.gov (United States)

Creative drama activities designed to help children learn difficult science concepts were integrated into an inquiry-based elementary science program. Children (n = 38) in an upper elementary enrichment program at one primary school were the participants in this action research. The teacher-researcher taught students the Full Option Science System™ (FOSS) modules of sound (fourth grade) and solar energy (fifth grade) with the integration of creative drama activities in treatment classes. A 2 × 2 × (2) Mixed ANOVA was used to examine differences in the learning outcomes and attitudes toward science between groups (drama and non-drama) and grade levels (4th and 5th grades) over time (pre/post). Learning was measured using the tests included with the FOSS modules. A shortened version of the Three Dimension Elementary Science Attitude Survey measured attitudes toward science. Students in the drama treatment group had significantly higher learning gains ( F = 160.2, p Creative drama was an effective strategy to increase science conceptual learning in this group of diverse elementary enrichment students when used as an active extension to the pre-existing inquiry-based science curriculum.

Discovering Plate Boundaries Update: Builds Content Knowledge and Models Inquiry-based Learning  

Science.gov (United States)

Discovering Plate Boundaries (DPB) is a jigsaw-structured classroom exercise in which students explore the fundamental datasets from which plate boundary processes were discovered. The exercise has been widely used in the past ten years as a classroom activity for students in fifth grade through high school, and for Earth Science major and general education courses in college. Perhaps more importantly, the exercise has been used extensively for professional development of in-service and pre-service K-12 science teachers, where it simultaneously builds content knowledge in plate boundary processes (including natural hazards), models an effective data-rich, inquiry-based pedagogy, and provides a set of lesson plans and materials which teachers can port directly into their own classroom (see Pringle, et al, this session for a specific example). DPB is based on 4 “specialty” data maps, 1) earthquake locations, 2) modern volcanic activity, 3) seafloor age, and 4) topography and bathymetry, plus a fifth map of (undifferentiated) plate boundary locations. The jigsaw is structured so that students are first split into one of the four “specialties,” then re-arranged into groups with each of the four specialties to describe the boundaries of a particular plate. We have taken the original DPB materials, used the latest digital data sets to update all the basic maps, and expanded the opportunities for further student and teacher learning. The earthquake maps now cover the recent period including the deadly Banda Aceh event. The topography/bathymetry map now has global coverage and uses ice-free elevations, which can, for example, extend to further inquiry about mantle viscosity and loading processes (why are significant portions of the bedrock surface of Greenland and Antarctica below sea level?). The volcanic activity map now differentiates volcano type and primary volcanic lithology, allowing a more elaborate understanding of volcanism at different plate boundaries. The volcanic activity map also now includes seafloor hydrothermal vents to extend the volcanic data set into the oceans. The new maps also more completely represent the polar regions, improving, for example, the students understanding of the ridge system running across the Arctic Sea. We have expanded the teacher’s guide to assist both novice and experienced teachers “see what an Earth Scientist sees” in the data. We have found repeatedly that the real strengths of the DPB activity are that (1) the course materials readily adapt to as well as appropriately challenge all levels of student abilities, leading to very natural differentiated levels of instruction, and (2) students of all levels develop a real ownership in their “plate tectonic” expertise.

Education and Professional Outreach for Scientists: Producing and Leveraging EPO Objects for Inquiry-Based Learning  

Science.gov (United States)

Most Education and Professional Outreach (EPO) by scientists reaches relatively small audiences. Most scientists also see their contributions to K-12 teaching rather limited due to their lack of experience in primary and secondary school education. These limitations remain a major barrier in bridging the gap between science and education, and in optimizing the effectiveness of EPO by scientists. As part of the Enduring Resources for Earth Science Education (ERESE) project, we have started to use web- templates in our EPO creation (http://earthref.org/ERESE). These templates are now being developed into web- based tools and services that will be served from the ERESE website and archived by the National Science Digital Library (NSDL). At EarthRef.org these EPO objects can be linked to teaching materials in the ERDA digital archive that can be displayed in a fashion allowing selection based on expert level and file type, in what we dubbed the "resource matrix" view. This is a powerful search mechanism for learners of all levels in which they can pre-screen materials to their own level, while allowing them to venture up to higher expert levels or to explore more simple cases at lower levels. This stimulates inquiry- based learning by permitting as much roaming freedom as possible in a "science-data- based" online environment. The current EarthRef.org and ERESE collections include websites for scientific projects, for classes taught and for expeditions, as well as a wide range of materials including press releases, video footage, science illustrations, interviews, data and diagrams, student reports and lesson plans. This collection is representative for EPO in any STEM discipline and provides much interesting materials that are useful for education. Our main goal is to provide scientists with tools so they can obtain an easy-to-use and highly leveraged outlet for their EPO efforts, where they can reach substantial numbers of learners and educators, and where their materials are archived as enduring resources for re-use by many.

Training Teachers to Use Technology and Inquiry-based Learning Practices in the Geosciences through an Industry-University Partnership  

Science.gov (United States)

Teacher professional development centered about the Geosciences is necessary in order to train K-12 teachers about this science field and to effectively educate K-12 students about Earth processes. The partnership of industries, universities, and K-12 schools is a collaborative pathway to support these efforts by providing teachers access to technology, inquiry-based learning, and authentic field experiences within the Geosciences context. This research presents the results of Project SMARTER (Science and Mathematics Advancement and Reform utilizing Technology and Enhanced Resources), a co-lead industry-university partnership and teacher professional development workshop program that focused on technology and inquiry-based learning in the Geosciences. The workshop included fifteen teachers from five distressed counties in Mississippi as defined by the Appalachian Regional Commission. Three (one science, once math, one technology) 7-12 grade teachers were selected from each school district and worked together during activities as a team to foster a cooperative learning experience. The two week workshop trained teachers on the use of a variety of technologies including: Vernier Probes and software, TI-calculators and presenter, Mimio Boards, GPS receivers, Google Earth, Excel, PowerPoint, projectors, and the use of historic geologic datasets. Furthermore, teachers were trained on proper field collection techniques, the use of Hach Kits and field probes, and the interpretation of geologic data. Each daily program incorporated the use of technology-rich and inquiry-based activities into one of the five Earth spheres: atmosphere, lithosphere, biosphere, hydrosphere, and anthrosphere. Results from the pre-post technology attitude survey showed that participating teachers significantly (p < 0.05) increased their confidence level in using technology. Furthermore, all participants self-reflected that the workshop both increased their interest in the Geosciences and their plans to integrate technology in future classroom activities. Qualitative responses from daily feedback forms and journal entries indicated that participating teachers were enthusiastic about inquiry-, technology-, and field-based learning activities and were willing to incorporate cross-discipline lesson plans. Evaluation of final lesson plans developed by the teachers during the workshop combined with follow-up classroom visits illustrated that the teachers appropriately developed classroom lessons to incorporate inquiry and technology and that they successfully implemented these lesson plans in their own classroom as a direct result of participating in workshop activities.

The effects of computer-supported inquiry-based learning methods and peer interaction on learning stellar parallax  

Science.gov (United States)

The presented research study investigated the effects of computer-supported inquiry-based learning and peer interaction methods on effectiveness of learning a scientific concept. The stellar parallax concept was selected as a basic, and yet important in astronomy, scientific construct, which is based on a straightforward relationship of several components presented in a simple mathematical equation: d = 1/p. The simplicity of the concept allowed the researchers to explore how the learners construct their conceptual knowledge, build mathematical skills and transfer their knowledge beyond the learning settings. A computer-based tutorial Stellar Parallax Interactive Restricted and Unrestricted Tutorial (SPIRUT) was developed for this study, and was designed to aid students' knowledge construction of the concept either in a learner-controlled or a program-controlled mode. The first investigated method in the study was enhancing engagement by the means of scaffolding for inquiry, which included scripted prompts and called for students' predictions and reflections while working in the learner-controlled or the computer-controlled version of SPIRUT. A second form of enhancing engagement was through peers working cooperatively during the learning activities. The students' level of understanding of the concept was measured by (1) the number of correct answers on a conceptual test with (2) several questions that require knowledge transfer to unfamiliar situations and (3) their ability to calculate the stellar parallax and find distances to stars. The study was conducted in the University of Missouri among 199 non-science major students enrolled in an introductory astronomy course in the fall semester 2010. The participants were divided into two main groups: one was working with SPIRUT and another group was a control group and utilized a paper-based tutorial. The SPIRUT group was further divided into the learner-controlled and the program-controlled subgroups. Students' learning achievements were measured by two post- tests and compared to the students' results on a pre-test. The first post-test was administered right after the treatment with aim to measure the immediate effect of the treatment. The second post-test was administered eight weeks later and was aimed to elicit how much of the constructed knowledge students retained after the treatment. Results of the study revealed that students who learned the concept with SPIRUT constructed greater conceptual knowledge and were able to better transfer it to another situation while their mathematical skills were equally improved as those students who worked with the paper-based tutorial. It was also evident that there was no difference between students' performances after their engagement with the learner-controlled or with the program-controlled version of SPIRUT. It was also found that students who worked independently constructed slightly greater knowledge than students who worked with peers. Albeit, there was no significant difference found of retention of knowledge after any type of treatment.

Open inquiry-based learning experiences: a case study in the context of energy exchange by thermal radiation  

Science.gov (United States)

An open inquiry (OI)-based teaching/learning experience, regarding a scientific investigation of the process of energy exchange by thermal radiation, is presented. A sample of upper secondary school physics teachers carried out this experience at the University of Palermo, Italy, in the framework of ESTABLISH, a FP7 European Project aimed at promoting and developing inquiry-based science education. The teachers had the opportunity to personally experience an OI-based learning activity, with the aim of exploring the pedagogical potentialities of this teaching approach to promote both the understanding of difficult concepts and a deeper view of scientific practices. The teachers were firstly engaged in discussions concerning real-life problematic situations, and then stimulated to design and carry out their own laboratory activities, aimed at investigating the process of energy exchange by thermal radiation. A scientific study on the energy exchange between a powered resistor and its surrounding environment, during the heating and cooling processes, was designed and performed. Here we report the phases of this experiment by following the teachers' perspective. A structured interview conducted both before and after the OI experience allowed us to analyze and point out the teachers' feedback from a pedagogical point of view. The advantages and limits of an OI-based approach to promote the development of more student-centred inquiry-oriented teaching strategies are finally discussed.

The Effects of Inquiry-Based Integrated Information Literacy Instruction: Four-Year Trends  

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of this study was to examine the effects of four-year integrated information literacy instruction via a framework of inquiry-based learning on elementary students’ memory and comprehension. Moderating factors of students’ academic achievement was another focus of this study. The subjects were 72 students who have participated in this study since they entered an elementary school in Chiayi district. This elementary school adopted the integrated information literacy instruction, designed by the researchers and elementary school teachers, and integrated it into various subject matters via a framework of inquiry-based learning, such as Super 3 and Big6 models. A series of inquiry-based integrated information literacy instruction has been implemented since the second semester of the subjects’ first grade. A total of seven inquiry learning projects has been implemented from grade one through grade four. Fourteen instruments were used as pretests and posttests to assess students’ factual recall and conceptual understanding of subject contents in different projects. The results showed that inquiry-based integrated information literacy instruction couldhelp students memorize facts and comprehend concepts of subject contents. Regardless ofacademic achievements, if students would like to devote their efforts to inquiry processes, their memory and comprehension of subject contents improvedeffectively. However, students of low-academic achievement might need more time to be familiar with the inquiry-based learning strategy.

In the first, students learn to perform inverse PCR to identify the genomic location of the GAL4 insertion, using FlyBase to identify flanking sequences and the primary literature to synthesize current knowledge regarding the nearest gene. In the second, we cross each GAL4 strain to a UAS-CD8-GFP reporter strain, and students perform whole mount CNS dissection, immunohistochemistry, confocal imaging, and analysis of developmental expression patterns. We have found these exercises to be very effective in teaching the uses and limitations of PCR and antibody-based techniques as well as critical reading of the primary literature and scientific writing. Students appreciate the opportunity to apply what they learn by generating novel data of use to the wider research community. PMID:25549104

A Design Model of Distributed Scaffolding for Inquiry-Based Learning  

Science.gov (United States)

This study presents a series of three experiments that focus on how distributed scaffolding influences learners' conceptual understanding and reasoning from combined levels of triangulation, at the interactive level (discourses within a focus group) and the collective level (class). Three inquiry lessons on plate tectonics (LPT) were designed, implemented and redesigned to explore how students responded to the scaffoldings provided. The results show that the goal-oriented version (LPT3) was significantly more effective at helping students develop an understanding of plate tectonics and evidence-based reasoning than the teacher-led (LPT1) and deconstructed (LPT2) versions ( ? 2 = 11.56, p effective and efficient, most likely due to synergies between teacher facilitation and lesson scaffolds. The empirical results clarify the functions of the design model proposed for distributed scaffolding: navigating inquiry, structuring tasks, supporting communication, and fostering reflection. Future studies should more closely evaluate the scaffolding system as a whole and synergies between different types of scaffolds for advancing learning.

Student-oriented learning: an inquiry-based developmental biology lecture course.  

Science.gov (United States)

In this junior-level undergraduate course, developmental life cycles exhibited by various organisms are reviewed, with special attention--where relevant--to the human embryo. Morphological features and processes are described and recent insights into the molecular biology of gene expression are discussed. Ways are studied in which model systems, including marine invertebrates, amphibia, fruit flies and other laboratory species are employed to elucidate general principles which apply to fertilization, cleavage, gastrulation and organogenesis. Special attention is given to insights into those topics which will soon be researched with data from the Human Genome Project. The learning experience is divided into three parts: Part I is a in which the Socratic (inquiry) method is employed by the instructor (GMM) to organize a review of classical developmental phenomena; Part II represents an in which students study the details related to the surveys included in Part I as they have been reported in research journals; Part III focuses on a class project--the preparation of a spiral bound book> on a topic of relevance to human developmental biology (e.g.,Textbook of Embryonal Stem Cells). Student response to the use of the Socratic method increases as the course progresses and represents the most successful aspect of the course. PMID:12705660

Learning to Become a More Effective Research or Inquiry-based Project Mentor  

Science.gov (United States)

How effective of a mentor are you? Have you thought much about this question? Have you participated in training to become a better mentor? For many academics, the typical three answers are "pretty good, I think ... why wouldn't I be?!"; "I am right now while reading this;" "Uh, no." The University of Wisconsin-Madison has developed a program called Research Mentor Training to help train scientists in myriad STEM (science, technology, engineering and mathematics) disciplines, including astronomy, for their crucial role of mentoring the next generation. Most of the field testing to date has focused on graduate students, post-docs, academic staff, and faculty mentoring undergraduate students who are participating in summer research experiences. The materials have proven quite effective in other areas as well, with only modest modifications. For example, several faculty cohorts concentrating on mentoring graduate students and post-docs have completed the training. In addition, the materials are used to prepare graduate students and undergraduates to mentor high school students. The preferred venue for the mentor training program is a seminar meeting one hour per week for 8 to 9 weeks, plus readings and outside activities, including mentoring a student. However, the structure is flexible, and some meaningful learning can occur in a single 90-minute interactive workshop like the one presented at the 2009 ASP annual meeting, "Science Education and Outreach: Forging a Path to the Future." All of the materials, including case studies, facilitator notes and guidelines, plus reading lists, are available online for no charge (http://researchmentortraining.org). Users can select pre-built curricula, or they can customize a package using a "shopping cart" interface.

Optimizing students' motivation in inquiry-based learning environments: The role of instructional practices  

Science.gov (United States)

The influence of inquiry science instruction on the motivation of 1360 minority inner-city seventh graders was examined. The project-based curriculum incorporates motivating features like real world questions, collaboration, technology, and lesson variety. Students design investigations, collect and analyze data, and create artifacts; challenging tasks require extensive use of learning and metacognitive strategies. Study 1 used Structural Equation Modeling to investigate student perceptions of the prevalence of project-based features, including real world connections, collaboration, academic press, and work norms, and their relation to interest, efficacy, cognitive engagement, and achievement. Perceptions of features related to different motivational outcomes, indicating the importance of using differentiated rather than single measures to study motivation in context. Cognitive engagement was enhanced by interest and efficacy but did not influence achievement, perhaps because students were not proficient strategy users and were new to inquiry. Study 2 examined the relationship between instructional practices and motivation. The 23 teachers in study 1 were observed six times during one unit. Observations focused on curriculum congruence, content accuracy, contextualization, sense making, and management and climate. A majority of teacher enactment was congruent with the curriculum, indicating that students experienced motivating features of project-based science. Hierarchical Linear Modeling showed that contextualization accounted for between-teacher variance in student interest, efficacy, and cognitive engagement; Teachers encouraged motivation through extended real world examples that related material to students' experiences. Cluster analysis was used to determine how patterns of practice affected motivation. Unexpectedly these patterns did not differentially relate to cognitive engagement. Findings showed that interest and efficacy were enhanced when teachers used particular sense making practices. These teachers provided explicit scaffolding for accomplishing complex tasks with questioning and feedback that highlighted key points. Teachers also used effective management practices and maintained a positive classroom climate. In contrast, a pattern of practice where teachers used questioning and feedback to press students to make connections and synthesize concepts without scaffolding support diminished motivation, because students may have needed more help to deal with challenge. Implications from both studies suggest inquiry teachers need to use explicit scaffolding and academic press together, with effective management practices, to support motivation.

Investigating the impact of a LEGO(TM)-based, engineering-oriented curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines  

Science.gov (United States)

This mixed method study examined the impact of a LEGO-based, engineering-oriented curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines. This study takes a social constructivist theoretical stance that science learning involves learning scientific concepts and their relations to each other. From this perspective, students are active participants, and they construct their conceptual understanding through the guidance of their teacher. With the goal of better understanding the use of engineering education materials in classrooms the National Academy of Engineering and National Research Council in the book "Engineering in K-12 Education" conducted an in-depth review of the potential benefits of including engineering in K--12 schools as (a) improved learning and achievement in science and mathematics, (b) increased awareness of engineering and the work of engineers, (c) understanding of and the ability to engage in engineering design, (d) interest in pursuing engineering as a career, and (e) increased technological literacy (Katehi, Pearson, & Feder, 2009). However, they also noted a lack of reliable data and rigorous research to support these assertions. Data sources included identical written tests and interviews, classroom observations and videos, teacher interviews, and classroom artifacts. To investigate the impact of the design-based simple machines curriculum compared to the scientific inquiry-based simple machines curriculum on student learning outcomes, I compared the control and the experimental groups' scores on the tests and interviews by using ANCOVA. To analyze and characterize the classroom observation videotapes, I used Jordan and Henderson's (1995) method and divide them into episodes. My analyses revealed that the design-based Design a People Mover: Simple Machines unit was, if not better, as successful as the inquiry-based FOSS Levers and Pulleys unit in terms of students' content learning. I also found that students in the engineering group outperformed students in the control group in regards to their ability to answer open-ended questions when interviewed. Implications for students' science content learning and teachers' professional development are discussed.

Impact of inquiry based distance learning and availability of classroom materials on physical science content knowledge of teachers and students in central Appalachia  

Science.gov (United States)

Physical science is important for developing scientific literacy yet a majority of teachers responsible for physical science courses do not have an academic degree in physical science. Programs aimed at increasing teacher content knowledge can be time consuming. This dissertation examines the impact of an inquiry based, professional development program offered via distance learning on teacher content knowledge and the role of teacher content knowledge on student understanding and attitudes toward science. Seventy-three teachers participated in the study, including Group I teachers (n = 39) who completed a distance learning course, a control group (Group II) with no intervention (n = 17), and Group III teachers (n = 17) who received classroom materials and no course intervention. A multiple-choice assessment was administered to teachers at the beginning and end of the summer. A similar multiple-choice assessment was administered during the school year to students (n=3,790) of those teachers. A teacher survey assessing the frequency of activity use and teachers' perceptions of the kit was administered to teachers at the end of the school year. A student survey assessing frequency of activities in the classroom, opinions of how to learn science, and attitudes toward science was administered to students during the school year. While Group II (50.6%) and Group III (52.2%) teacher scores were both lower than Group I teacher scores (67.4%), students in Group III (42.9%) outperformed students in Group II (39.4%) following instruction, at a level equal to Group I students (43.6%). Thus, providing materials/activities was as effective at increasing student understanding as providing materials/activities and increasing teacher understanding. However, while teachers in Group I and III report similar use of and satisfaction with the materials/activities, the percentage of Group I students reporting frequent use of inquiry based activities in the classroom, strong belief that inquiry based activities help them learn science, and positive attitudes toward science increased, while the percentages of students in Groups II and III decreased. These results suggest that in order to maximize students' understanding of and attitudes toward science, professional development programs should not only include inquiry pedagogy and laboratory materials but also emphasize teacher understanding.

Investigating engagement, thinking, and learning among culturally diverse, urban sixth graders experiencing an inquiry-based science curriculum, contextualized in the local environment  

Science.gov (United States)

This mixed-methods study combined pragmatism, sociocultural perspectives, and systems thinking concepts to investigate students' engagement, thinking, and learning in science in an urban, K-8 arts, science, and technology magnet school. A grant-funded school-university partnership supported the implementation of an inquiry-based science curriculum, contextualized in the local environment through field experiences. The researcher worked as co-teacher of 3 sixth-grade science classes and was deeply involved in the daily routines of the school. The purposes of the study were to build a deeper understanding of the complex interactions that take place in an urban science classroom, including challenges related to implementing culturally-relevant instruction; and to offer insight into the role educational systems play in supporting teaching and learning. The central hypothesis was that connecting learning to meaningful experiences in the local environment can provide culturally accessible points of engagement from which to build science learning. Descriptive measures provided an assessment of students' engagement in science activities, as well as their levels of thinking and learning throughout the school year. Combined with analyses of students' work files and focus group responses, these findings provided strong evidence of engagement attributable to the inquiry-based curriculum. In some instances, degree of engagement was found to be affected by student "reluctance" and "resistance," terms defined but needing further examination. A confounding result showed marked increases in thinking levels coupled with stasis or decrease in learning. Congruent with past studies, data indicated the presence of tension between the diverse cultures of students and the mainstream cultures of school and science. Findings were synthesized with existing literature to generate the study's principal product, a grounded theory model representing the complex, interacting factors involved in teaching and learning. The model shows that to support learning and to overcome cultural tensions, there must be alignment among three main forces or "causal factors": students, teaching, and school climate. Conclusions emphasize system-level changes to support science learning, including individualized support for students in the form of differentiated instruction; focus on excellence in teaching, particularly through career-spanning professional support for teachers; and attention to identifying key leverage points for implementing effective change.

The effects on community college student physics achievement and attitudes about learning physics due to inquiry-based laboratory activities versus cookbook laboratory activities  

Science.gov (United States)

The purpose of this quasi-experimental study was to determine the effects on community college student physics conceptual achievement and attitudes about learning physics due to the use of inquiry-based laboratory activities versus cookbook laboratory activities. An analysis of covariance (ANCOVA) was performed to test for differences in mean post-test Force Concept Inventory (FCI) score for two different types of physics lab instruction (IL versus CBL). Results of the ANCOVA, F (1, 35) = 0.761, p physics lab instruction (IL versus CBL)., however, the covariate and the dependent variable were shown to not be linearly related. Therefore, a one-way analysis of variance (ANOVA) was used to compare MBT scores. The results of the ANOVA, F (1, 36) = 0.066, p science reasoning sub-scores. The FCI pre-test score and ACT science score were shown to be the best predictors of FCI post-test score. Another step-wise multiple linear regression was used to analyze the relationships between the MBT post-test score and type of instruction, MBT pre-test score, and ACT science reasoning sub-scores. The ACT Science sub-scores were determined to be the best predictor of MBT post-test score. An independent t-test was used to compare the mean lecture test grades for the lab groups taught using inquiry and cookbook methods. The mean lecture test scores of the inquiry-based lab group (M = 81.39, S.D. = 8.15) were found to be significantly higher, t (36) = -2.021, p Science Survey (CLASS) percent favorable scores for the lab groups taught using inquiry and cookbook methods. Results of the t-test, t (36) = 0.897, p < 0.376, failed to reject the null hypothesis that the CLASS scores differed by lab instruction type.

The Effect of Interactive Whiteboard Supported Inquiry-Based Learning on Achievement and Motivation in Physics and Views of Prospective Teachers Toward the Instruction  

Directory of Open Access Journals (Sweden)

Full Text Available In this study, the effects of interactive whiteboard supported inquiry- based learning approach on the academic achievement and motivation in modern physics teaching have been investigated and the views of prospective teachers toward the teaching supported by interactive whiteboard have been defined. In this study, patterned in the form of quasi-empirical model and supported with pre- and post-test control groups, data were collected by academic achievement tests, motivation scales and semi-structured interview forms. While traditional method was used to deliver lectures to the control group, interactive white board was used to deliver experimental group lectures enriched with activities such as simulations, videos and animations. Thus, it has been taken advantages of technology support in the processes of orienting and asking questions, identification of problems, hypothesis generation, testing and planning. In addition to these, the processes of measuring, drawing a graphs, controlling the variables and data interpretation have also been supported by simulations in lectures. As a result of applications, it has been achieved that the teaching materials used in experimental group significantly increased the students’ motivations and academic achievements. Moreover, it also has been obtained that prospective teachers had positive opinions; such as funny (amusing lecture environment, increasing the participation, concretization of the abstract concepts, facilitating the learning and providing permanence on applications in this study.

Mathematical modeling and kinematics: A study of emerging themes and their implications for learning mathematics through an inquiry-based approach  

Science.gov (United States)

In recent years, emphasis on student learning of mathematics through "real world" problems has intensified. With both national and state standards calling for more conceptual learning and understanding of mathematics, teachers must be prepared to learn and implement more innovative approaches to teaching mathematical content. Mathematical modeling of physical phenomena is presented as a subject for new and developing research areas in both teacher and student learning. Using a grounded theory approach to qualitative research, this dissertation presents two related studies whose purpose was to examine the process by which in-service teachers and students enrolled in an undergraduate physics course constructed mathematical models to describe and predict the motion of an object in both uniform and non-uniform (constant acceleration) contexts. This process provided the framework for the learners' study of kinematics. Study One involved twenty-three in-service physics and math teachers who participated in an intensive six-hour-a-day, five-day unit on kinematics as part of a professional development institute. Study Two involved fifteen students participating in the same unit while enrolled in a physics course designed for pre-service teachers and required in their undergraduate or graduate degree programs in math and science education. Qualitative data, including videotapes of classroom sessions, field notes, researcher reflections, and interviews are the focus of analysis. The dissertation presents and analyzes tensions between learner experience, learning standard concepts in mathematics and learning standard concepts in physics within a framework that outlines critical aspects of mathematical modeling (Pollak, 2003): (1) understanding a physical situation, (2) deciding what to keep and what not to keep when constructing a model related to the situation, and (3) determining whether or not the model is sufficient for acceptance and use. Emergent themes related to the construction of the learners' models included several robust conceptions of average velocity and considerations of what constitutes a "good enough" model to use when describing and predicting motion. The emergence of these themes has implications for teaching and learning mathematics through an inquiry-based approach to kinematics.

An inquiry-based laboratory on friction  

CERN Document Server

Sliding friction is usually introduced in high school, but rarely through activities in laboratory. A qualitative introduction to friction is presented by proposing exploration of different kind of materials in order to suggest which aspects can be relevant and which interaction is involved. Different quantitative experiments are proposed for studying Leonardo's laws for friction. The learning path was tested with two high school classes during an instruction trip at department. Students were engaged in the inquiry-based introductory activity and seemed to realize with care the measurements. However, the analysis of their reports shows some learning difficulties.

Conceptualising inquiry based education in mathematics  

DEFF Research Database (Denmark)

The terms inquiry-based learning (IBL) and inquiry-based education (IBE) have appeared with increasing frequency in educational policy and curriculum documents related to mathematics and science education over the past decade, indicating a major educational trend. We go back to the origin of inquiry as a pedagogical concept in the work of Dewey (e.g. 1916, 1938) to analyse and discuss its migration to science and mathematics education. For conceptualizing inquiry-based mathematics education (IBME) it is important to analyse how this concept resonates with already well-established theoretical frameworks in mathematics education. Six such frameworks are analysed from the perspective of inquiry: the problem-solving tradition, the Theory of Didactical Situations, the Realistic Mathematics Education programme, the mathematical modelling perspective, the Anthropological Theory of Didactics, and the dialogical and critical approach to mathematics education. In an appendix these frameworks are illustrated with paradigmatic examples of teaching activities with inquiry elements. The paper is rounded off with a list of ten concerns for the development and implementation of IBME.

Inquiry-Based Mathematics Education  

OpenAIRE

Inquiry-based mathematics education (IBME) refers to a student-centered paradigm of teaching mathematics and science, in which students are invited to work in ways similar to how mathematicians and scientists work. This means they have to observe phenomena, ask questions, look for mathematical and scientific ways of how to answer these questions (like carrying out experiments, systematically controlling variables, drawing diagrams, calculating, looking for patterns and relationships, making c...

Inquiry-based Teaching in Second and Foreign Language Pedagogy  

Directory of Open Access Journals (Sweden)

Full Text Available It is the consensus among language educators that the objectives of teaching a second/foreign language (L2 put stress on the enhancement of students’ communication skills and advocate the importance of interaction in the classroom. In addition to theories and methods exclusively dedicated to language instruction, the domain-independent inquiry-based teaching, a cognitive approach, can be easily and effectively integrated into the L2 classroom which echoes the concerns and needs in L2 education. Inquiry teaching is characterized by its question-answer interactive information exchanges. Instead of learning passively, it stimulates students to actively engage in cognitive and discovery learning activities. It is assumed that this active, discovery, or Socratic teaching approach promotes the dynamics in class, draws and maintains students’ attention, reinforces meaningful communication, deepens and expands intellectual capacity, and facilitates learning transfer. Most importantly, it supports the development of learner’s cognitive and metacognitive strategies. This technique best fits within the theme-based text and can be conducted in an expanding spiral pattern. A questionnaire was administered in a Chinese as a second language class to assess students’ feedback on the effectiveness and preference of this approach and favorable findings were revealed. Students expressed enthusiasm on inquiry-based teaching and indicated that this approach reinforced their learning and understanding of the course material. Qualitative data also shows that inquiry-based teaching enhanced students’ classroom engagement and fostered an effective and meaningful learning experience.

GeoMapApp Learning Activities: Grab-and-go inquiry-based geoscience activities that bring cutting-edge technology to the classroom  

Science.gov (United States)

NSF-funded GeoMapApp Learning Activities (http://serc.carleton.edu/geomapapp) provide self-contained learning opportunities that are centred around the principles of guided inquiry. The activities allow students to interact with and analyse research-quality geoscience data to explore and enhance student understanding of underlying geoscience content and concepts. Each activity offers ready-to-use step-by-step student instructions and answer sheets that can be downloaded from the web page. Also provided are annotated teacher versions of the worksheets that include teaching tips, additional content and suggestions for further work. Downloadable pre- and post- quizzes tied to each activity help educators gauge the learning progression of their students. Short multimedia tutorials and details on content alignment with state and national teaching standards round out the package of material that comprises each "grab-and-go" activity. GeoMapApp Learning Activities expose students to content and concepts typically found at the community college, high school and introductory undergraduate levels. The activities are based upon GeoMapApp (http://www.geomapapp.org), a free, easy-to-use map-based data exploration and visualisation tool that allows students to access a wide range of geoscience data sets in a virtual lab-like environment. Activities that have so far been created under this project include student exploration of seafloor spreading rates, a study of mass wasting as revealed through geomorphological evidence, and an analysis of plate motion and hotspot traces. The step-by-step instructions and guided inquiry approach lead students through each activity, thus reducing the need for teacher intervention whilst also boosting the time that students can spend on productive exploration and learning. The activities can be used, for example, in a classroom lab with the educator present and as self-paced assignments in an out-of-class setting. GeoMapApp Learning Activities are hosted on the SERC-Carleton web site.

Is adolescence a critical period for learning formal thinking skills? A case study investigating the development of formal thinking skills in a short-term inquiry-based intervention program  

Science.gov (United States)

Current domestic and international comparative studies of student achievement in science are demonstrating that the U.S. needs to improve science education if it wants to remain competitive in the global economy. One of the causes of the poor performance of U.S. science education is the lack of students who have developed the formal thinking skills that are necessary to obtain scientific literacy. Previous studies have demonstrated that formal thinking skills can be taught to adolescents, however only 25% of incoming college freshman have these necessary skills. There is some evidence that adolescence (girls aged 11-13, boys aged 12-14) is a critical period where students must learn formal thinking skills, similar to the critical period that exists for young children learning languages. It is not known whether it is more difficult for students to learn formal thinking skills either prior to or following adolescence. The purpose of this quantitative case study is to determine whether adolescence is a critical period for students to learn formal thinking skills. The study also investigates whether a formal thinking skills focused program can improve students' intelligence. In this study 32 students who had not developed any formal thinking skills, ranging in age from 10-16, underwent an intensive four-week, inquiry-based, formal thinking skill intervention program that focused on two formal thinking skills: (1) the ability to control and exclude variables; and (2) the ability to manipulate ratios and proportionalities. The students undergoing the training were matched with control students by age, gender, formal thinking skill ability, and intelligence. The control group attended their traditional science course during the intervention periods. The results of the study showed that the intervention program was successful in developing students' formal thinking skills. The pre-adolescents (males, age 10-11, females, age 10) were unable to learn formal thinking skills. The data indicated that there is not a significant difference between adolescents and post-adolescents (up to 16-years-old) ability to learn formal thinking skills. Both groups (adolescent and post-adolescent) showed improvement in their formal thinking skill ability after the intervention. The intervention also demonstrated evidence of improving students' intelligence scores.

The Integration of the Big6 Information Literacy and Reading Strategies Instruction in a Fourth Grade Inquiry-Based Learning Course, “Our Aquarium”  

Directory of Open Access Journals (Sweden)

Full Text Available This study investigated the student performance in an inquiry learning course which integrated information literacy and reading strategies in a fourth-grade science class. The curriculum design was based on the Big6 model, which includes the stages of task definition, information seeking strategies, location & access, use of information, synthesis, and evaluation. The study duration was one semester. The data was gathered through participant observations, interviews, surveys, tests, and from documents generated in the course implementation. The results showed that the integration of information literacy and reading strategies instruction was feasible. The students performed well in information seeking strategies, locating & accessing information, using and synthesizing information. In contrast, their abilities in task definition and evaluation needed further improvement. Also, while the students did acquire various reading strategies during the inquiry process, they needed more exercises to internalize the skills. The performance on the acquisition of subject knowledge was also improved through the inquiry learning. The participating instructors considered that the collaboration between teachers of different subject matters was the key to a successful integrated instruction [Article content in Chinese

The effect of inquiry-based, hands-on labs on achievement in middle school science  

Science.gov (United States)

The purpose of this quasi-experimental study was to measure the difference in science achievement between students who had been taught with an inquiry-based, hands-on pedagogical approach and those who had not. Improving student academic achievement and standardized test scores is the major objective of teachers, parents, school administrators, government entities, and students themselves. One major barrier to this academic success in Georgia, and the entire United States, has been the paucity of success in middle level science classes. Many studies have been conducted to determine the learning approaches that will best enable students to not only acquire a deeper understanding of science concepts, but to equip them to apply that new knowledge in their daily activities. Inquiry-based, hands-on learning involves students participating in activities that reflect methods of scientific investigation. The effective utilization of the inquiry-based learning approach demands inclusion of learners in a self-directed learning environment, the ability to think critically, and an understanding of how to reflect and reason scientifically. The treatment group using an inquiry-based, hands-on program did score slightly higher on the CRCT. However, the results revealed that there was not a significant difference in student achievement. This study showed that the traditionally instructed control group had slightly higher interest in science than the inquiry-based treatment group. The findings of this research study indicated that the NCLB mandates might need to be altered if there are no significant academic gains that result from the use of inquiry-based strategies.

Inquiry-Based Science: Turning Teachable Moments into Learnable Moments  

Science.gov (United States)

This study examines how an inquiry-based approach to teaching and learning creates teachable moments that can foster conceptual understanding in students, and how teachers capitalize upon these moments. Six elementary school teachers were videotaped as they implemented an integrated inquiry-based science and literacy curriculum in their classrooms. In this curriculum, science inquiry implies that students search for evidence in order to make and revise explanations based on the evidence found and through critical and logical thinking. Furthermore, the curriculum material is designed to address science key concepts multiple times through multiple modalities (do it, say it, read it, write it). Two types of teachable moments were identified: planned and spontaneous. Results suggest that the consolidation phases of inquiry, when students reinforce new knowledge and connect their empirical findings to theory, can be considered as planned teachable moments. These are phases of inquiry during which the teacher should expect, and be prepared for, student utterances that create opportunities to further student learning. Spontaneous teachable moments are instances when the teacher must choose to either follow the pace of the curriculum or adapt to the students' need. One implication of the study is that more teacher support is required in terms of how to plan for and effectively utilize the consolidation phases of inquiry.

The relationship between inquiry-based science instruction and student achievement  

Science.gov (United States)

Teaching science through inquiry has become a focus of recent educational reform in Mississippi and other states. Based on the Constructivist learning theory, inquiry instruction can take many forms, but generally follows the scientific method by requiring students to learn concepts through experimentation and real-world, hands-on experiences. This dissertation examines the relationship between the amounts of time spent using inquiry-based science instruction and student achievement as measured by the Mississippi State Science Assessment. The study also identifies teacher perceptions of inquiry and the amount of professional development received by participants on using inquiry-based instructional techniques. Finally, this study identifies factors that hinder the use of inquiry. Using a 24-question written survey, the researcher collected quantitative data from 204 science teachers in grades K-8 in four southern Mississippi school districts. Participants rated their average amount of time spent using inquiry-based science instruction in their classrooms. These results were then compared to each school's average test score on the 2009-2010 Mississippi State Science Assessment using a Spearman rho correlation. A significant positive relationship was found between amounts of time spent using inquiry-based science instruction and student achievement. The participants also indicated their perceptions of inquiry, amount of professional development, and deterrents to inquiry usage on a five-point Likert scale survey. Overall, participants held a favorable opinion of inquiry-based instruction and felt that it was important for their students' success. Over half of participants had not attended professional development on inquiry-based instruction. A majority indicated a desire for professional development. The most commonly identified factor hindering the use of inquiry was a lack of materials and resources. Many participants also indicated that time constraints prevented more frequent use of inquiry in their classrooms.

Assessing the effectiveness of an inquiry-based science education professional development  

Science.gov (United States)

Both inquiry-based science teaching and online learning opportunities have grown in popularity with recent pressures in the educational field. Despite such interest in both topics, there is both conflicting research and limited research in the effectiveness of inquiry-based teaching methods and online learning respectively. This study focused on the Neighborhood Academic Initiative STEM (NAI-STEM) professional development program that concentrated on inquiry science learning using an online platform. The attendees participated in both synchronous and asynchronous online sessions that facilitated their implementation of an inquiry-based curriculum to urban high school students around the University of Southern California area. The effectiveness of this professional development was assessed using Kirkpatrick's Four Levels of Evaluation model (1996), utilizing tools such as pre- and post-surveys, teacher observations and interviews, and student pre- and post-assessment scores. Results suggest that inquiry-based teaching is effective in increasing student science academic achievement, but further studies should be conducted to test the generalizability of this professional development design.

Inquiry-based Science Instruction in High School Biology Courses: A Multiple Case Study  

Science.gov (United States)

A lack of research exists about how secondary school science teachers use inquiry-based instruction to improve student learning. The purpose of this qualitative study was to explore how science teachers used inquiry-based instruction to improve student learning in high school biology courses. The conceptual framework was based on Banchi and Bell's model of increasing levels of complexity for inquiry-based instruction. A multiple case study research design was conducted of biology programs at 3 high schools in an urban school district in the northeastern region of the United States. Participants included 2 biology teachers from each of the 3 high schools. Data were collected from individual interviews with biology teachers, observations of lessons in biology, and documents related to state standards, assessments, and professional development. The first level of data analysis involved coding and categorizing the interview and observation data. A content analysis was used for the documents. The second level of data analysis involved examining data across all sources and all cases for themes and discrepancies. According to study findings, biology teachers used confirmation, structure, and guided inquiry to improve student learning. However, they found open inquiry challenging and frustrating to implement because professional development about scaffolding of instruction over time was needed, and students' reading and writing skills needed to improve. This study contributes to positive social change by providing educators and researchers with a deeper understanding about how to scaffold levels of inquiry-based science instruction in order to help students become scientifically literate citizens.

Life-Cycle Thinking in Inquiry-Based Sustainability Education – Effects on Students’ Attitudes towards Chemistry and Environmental Literacy  

Directory of Open Access Journals (Sweden)

Full Text Available The aim of the present study is to improve the quality of students’ environmental literacy and sustainability education in chemistry teaching by combining the socio-scientific issue of life-cycle thinking with inquiry-based learning approaches. This case study presents results from an inquiry-based life-cycle thinking project: an interdisciplinary teaching model designed by chemistry teachers. The strength of the project is that upper-secondary students (N=105 are allowed to investigate the life cycle of an optional product based on their own interest. Studentcentred teaching methods are suggested to promote the students’ interest in studying. The research question was: How does an inquiry-based life-cycle thinking project in chemistry education affect students’ chemistry attitudes and environmental literacy? The research methods used included surveys and semi-structured interviews. The study shows that the project positively affected students’ attitudes towards chemistry learning: they valued the independent and collaborative learning setting. The changes in the students’ environmental literacy were evident in their new realisations: they emphasised the importance of environmental protection and recycling, but perceived that changing their own behaviour is still difficult. The inquiry-based teaching of life-cycle thinking can be seen as an effective approach to more motivating and sustainable chemistry education. Further research should address the kinds of knowledge outcomes that this type of inquiry-based life-cycle teaching creates in students. Furthermore, other useful approaches to teaching sustainable development in chemistry lessons should be shared.

Classroom questioning strategies as indicators of inquiry based science instruction  

Science.gov (United States)

Inquiry teaching often rests upon the assumption that through the use of questioning and response strategies, teachers can stimulate students to actively construct knowledge. Based on this hypothesis, middle-school science lessons were observed and questioning and response strategies were identified that are related to inquiry-based instruction. Twenty-four science lessons were observed, videotaped, and ranked by inquiry characteristics other than questioning strategy. The video and audio portions of the recordings were analyzed to determine the student and teacher's questioning and response strategies in each classroom. These strategies were then compared to teaching style, along a continuum from traditional to inquiry, to identify questioning and response strategies that stimulate students to ask questions, solve problems, analyze evidence, consider alternative explanations, and other similar inquiry behaviors. The analyses indicated several questioning strategies of teachers that are related to inquiry teaching and learning and might be used as indicators of inquiry teaching in middle school science lessons. These include the number of content-related questions asked by teachers, the number of divergent questions asked by teachers, the number of times teachers probe for the intended response, the number of times teachers answer students' questions, and the number questions per concept asked by teachers. Perhaps more important was the observation that even after several decades of emphasizing the importance of inquiry methods in science education, neither students nor teachers participating in this study are asking higher-level cognitive questions deemed to be an important facet in the effective teaching and learning of science.

The purpose of this quasi-experimental study was to determine the effects of a field-based, inquiry-focused course on pre-service teachers' geoscience content knowledge, attitude toward science, confidence in teaching science, and inquiry understanding and skills. The field-based course was designed to provide students with opportunities to observe, compare, and investigate geological structures in their natural environment and to gain an understanding of inquiry via hands-on learning activities designed to immerse students in authentic scientific investigation. ANCOVA and MANCOVA analyses examining differences in outcome measures between students in the field experience ( n = 25) and education students enrolled in the traditional, classroom-based course ( n = 37) showed that students in the field course generally had significantly higher scores. Results provide evidence of the value of the field and inquiry-based approach in helping pre-service teachers develop the needed skills and knowledge to create effective inquiry-based science lessons.

Pre-Nursing Students Perceptions of Traditional and Inquiry Based Chemistry Laboratories  

Science.gov (United States)

This paper describes a process that attempted to meet the needs of undergraduate students in a pre-nursing chemistry class. The laboratory was taught in traditional verification style and students were surveyed to assess their perceptions of the educational goals of the laboratory. A literature review resulted in an inquiry based method and analysis of the needs of nurses resulted in more application based activities. This new inquiry format was implemented the next semester, the students were surveyed at the end of the semester and results were compared to the previous method. Student and instructor response to the change in format was positive. Students in the traditional format placed goals concerning technique above critical thinking and felt the lab was easy to understand and carry out. Students in the inquiry based lab felt they learned more critical thinking skills and enjoyed the independence of designing experiments and answering their own questions.

Investigation of Inquiry-based Science Pedagogy among Middle Level Science Teachers: A Qualitative Study  

Science.gov (United States)

This study implemented a qualitative approach to examine the phenomenon of "inquiry-based science pedagogy or inquiry instruction" as it has been experienced by individuals. Data was collected through online open-ended surveys, focus groups, and teacher reported self-reflections to answer the research questions: 1) How do middle level science teachers conceptualize "inquiry-based instruction?" 2) What are preferred instructional strategies for implementation in middle level science classrooms? And 3) How do middle level science teachers perceive the connection between science instruction and student learning? The participants within this research study represent 33 percent of teachers in grades 5 through 9 within six school districts in northeastern Pennsylvania. Of the 12 consent forms originally obtained, 10 teachers completed all three phases of the data collection, including the online survey, participation in focus groups, and teacher self-reflection. 60 percent of the participants taught only science, and 40 percent taught all content areas. Of the ten participants, 50 percent were certified teachers of science and 50 percent were certified as teachers of elementary education. 70 percent of the research participants reflected having obtained a master's, with 60 percent of these degrees being received in areas of education, and 10 percent in the area of science. The research participants have a total of 85 collective years of experience as professional educators, with the average years of experience being 8.5 years. Analysis of data revealed three themes related to research question #1) How do middle-level science teachers conceptualize inquiry-based instruction? and sub-question #1) How do middle-level science teachers characterize effective instruction? The themes that capture the essence of teachers' formulation of inquiry-based instruction that emerged in this study were student centered, problem solving, and hands-on . Analysis of data revealed one theme related to research question #2) What are preferred instructional strategies for implementation in middle level science classrooms? and topical sub-question #2) How do middle level science teachers structure instruction. The theme that emerged was needs of students. Analysis of the data revealed one theme related to research question #3) How do middle level science teachers perceive the relationship between science instruction and student learning? and topical sub-question #3) How do middle level science teachers view their role in relation to student learning? This theme is meaning making. Analysis of the data related to meaning making revealed two sub-themes of application and relationships. It is clear that middle level science teachers have a vision for inquiry-based science instruction, but implementation is inhibited by a variety of factors including curricular programming that is very broad and lacks depth, the scheduling of time and resources for science, and the absence of a clear model of inquiry-based instruction. In addition, only one participant referenced students investigating their own authentic questions and no participants reflected on the importance of students using evidence in their explanations of scientific phenomenon. Additionally, participants continually reflected on the needs of their students informing instructional practices, and it is wondered if there is a clear understanding among middle level teachers of how students learn science. Real world applications were recognized as important within science learning and the researcher questions whether teachers of science have adequate opportunities to explore real world application of science concepts throughout their careers in order to foster connections within the classroom. These findings support the need for strong, job-embedded professional development, the cultivation of learning communities dedicated to the investigation and implementation of inquiry-based science, the focusing of curricular programming to allow for in depth investigation of scientific concep

Science for all: Experiences and outcomes of students with visual impairment in a guided inquiry-based classroom  

Science.gov (United States)

The purpose of this study was to examine instructional experiences of students with visual impairment in an guided inquiry-based science classroom. Drawing from social constructive perspectives about teaching and learning, I focused on the initial attempts of students to participate fully in an inquiry-based astronomy unit. The astronomy unit incorporated features of project-based science inquiry and aligned with national standards. This study described the opportunities provided to and challenges faced by students with visual impairment as they participated in the guided inquiry-based learning environment. Additionally, discursive practices of students including student-generated questions, student discussions, and students' science notebook writing were examined. Also, students' alternative conceptions about scientific phenomena and changes in students' thinking during the course of instruction, if any, were described. Methods of data collection included classroom observations, video records, pre- and post-curriculum assessments, attitudes toward science measurement, student interviews, and student artifacts (i.e., science notebook entries, student-constructed models). Findings showed that student learning was enhanced when the instructor-researcher guided students in accomplishing inquiry tasks and in making sense of their inquiry experiences. Additionally, the use of appropriate reflective prompts assisted students with visual impairment to fully participate in the writing tasks of the inquiry-based learning environment. Results suggested that the quantity and quality of student-generated questions increased with extended inquiry instruction. Also, students used questions to not only establish verbal communication, but to elaborate on their own thinking and expand or explain the thinking of others. Findings suggested also that students with visual impairment have similar alternative frameworks about scientific phenomena (i.e., causes of lunar phases, reason for the seasons) as do their peers with sight. This study contributes to the literature about inquiry-based instructional strategies for all students and initiates the conversation about best practice for science instruction with students with visual impairment.

PDI: Discussion and Writing in the Inquiry Based Elementary Science Classroom: Critical partners in the development of scientific reasoning and conceptual understanding, New Orleans, Louisiana; March 18, 2009  

Science.gov (United States)

This Professional Development Institute focuses on the development and use of literacy skills in science to foster upper elementary (3rd-5th grade) students' scientific reasoning as they move from direct experience to conceptual understanding. To set the stage and establish a model of classroom based guided inquiry, participants will first engage in a brief science investigation. This will be followed by an in-depth exploration of the roles of oral and written language in deepening scientific reasoning. Using classroom videos, transcripts of student discussions, student writing, and mini-case studies, we will identify a range of instructional strategies that: structure and guide serious accountable talk among students; foster careful use of notebooks for recording and concluding; and provide opportunities for students to apply their understanding through different genres of writing. We will also focus on the relationship between talking and writing and the important back and forth that takes place as students clarify and deepen their understanding of science ideas. Participants also will have the opportunity to explore the relationship between literacy and science teaching and learning and the important connections that can and should be made in the classroom. Much is being made of the connection between science and literacy in many educational arenas. Publishers are producing science readers by the dozen. Science journals and science notebooks are more and more common. Teachers and other educational leaders are emphasizing the connection in the hopes of keeping science off the back burner. Others see science as a way to motivate students to build their literacy skills and improve test scores. This institute stems from the growing literature on the role of discussion and writing in interpreting, analyzing and synthesizing the ideas and experiences of scientific investigations. There is little doubt that direct experience with science phenomena is critical to student science learning, but it does not in itself lead to the development of conclusions and new theories. For this to take place students need to reflect on their experience, examine and analyze their data, debate and discuss their ideas, write down their conclusions, and communicate them to others. In other words they need to use language - literacy. How they use language and what teachers do to support this is the focus of this institute. This institute is intended for science educators interested in exploring how discussion and writing permeate effective inquiry based instruction at the upper elementary level (3-5th grade). In large and small highly interactive groups, participants will have the opportunity to learn from the resources provided by the institute leaders as well as from one another. The presenters of the workshop reflect a critical partnership between literacy and science educators. Three of the presenters of this institute are science educators with many years of experience in developing inquiry based curricula, working with both pre-service and in-service teachers on inquiry based science teaching and learning. One of the presenters is an expert in comprehensive literacy and has many years experience providing professional development to teachers. In 2003, the Center for Science Education at EDC received an NSF grant to develop professional development materials to enhance the use of language in the inquiry based classroom with a particular focus on science discussions; student writing in notebooks and in other contexts; and the explicit connection between the teaching and learning of literacy and that of science. This institute is based on this work.

Inquiry-Based Instruction and High Stakes Testing  

Science.gov (United States)

Science education is a key to economic success for a country in terms of promoting advances in national industry and technology and maximizing competitive advantage in a global marketplace. The December 2010 Program for International Student Assessment (PISA) ranked the United States 23rd of 65 countries in science. That dismal standing in science proficiency impedes the ability of American school graduates to compete in the global market place. Furthermore, the implementation of high stakes testing in science mandated by the 2007 No Child Left Behind (NCLB) Act has created an additional need for educators to find effective science pedagogy. Research has shown that inquiry-based science instruction is one of the predominant science instructional methods. Inquiry-based instruction is a multifaceted teaching method with its theoretical foundation in constructivism. A correlational survey research design was used to determine the relationship between levels of inquiry-based science instruction and student performance on a standardized state science test. A self-report survey, using a Likert-type scale, was completed by 26 fifth grade teachers. Participants' responses were analyzed and grouped as high, medium, or low level inquiry instruction. The unit of analysis for the achievement variable was the student scale score average from the state science test. Spearman's Rho correlation data showed a positive relationship between the level of inquiry-based instruction and student achievement on the state assessment. The findings can assist teachers and administrators by providing additional research on the benefits of the inquiry-based instructional method. Implications for positive social change include increases in student proficiency and decision-making skills related to science policy issues which can help make them more competitive in the global marketplace.

Overcoming the difficulties of inquiry-based teaching through the use of coaching  

Science.gov (United States)

This research examines the use of coaching as a professional development approach to enhance the introduction of inquiry-based teaching methods. Previous professional development efforts are well documented in the science education literature, and implementation rates are generally low, despite a wide-spread belief that inquiry-based teaching methods are beneficial to student learning. Difficulties that are often found include a lack of time, tension from high-stakes testing, a lack of content knowledge, a lack of inquiry knowledge, a scarcity of inquiry resources, and a conflict between the teacher's learning style and the inherent style of inquiry. These barriers lead to slow, poorly understood progress in adopting inquiry methods, and a shortage of concrete suggestions on how best to proceed. To examine how teacher-coach pairs overcome these difficulties, a multiple-case study was planned that uncovered specific steps taken by creating a richly detailed narrative of how this science curriculum is implemented. This narrative was closely affiliated with a certain specific context of underperforming high schools in a major American city, but the results may generalize to other similar contexts as well. Additionally, the findings from these case studies may serve to validate other analogous findings from the literature.

Content knowledge and classroom inquiry style: Factors influencing inquiry-based science teaching practice of elementary student teachers  

Science.gov (United States)

This comparative case study examines the relationship between substantive content knowledge (SCK) of science concepts and inquiry-based teaching of those concepts through fine-grained analysis of the science teaching practice of three elementary student teachers in their final year of teacher preparation carried out within an elementary professional development school program (a partnership between a major northeastern university and a neighboring school district), resulting in numerous similarities in teaching context among the three participants. I examined four elements for each participant followed by cross-case analysis: (1) specific problematic content knowledge-related teaching events that arose during inquiry-based teaching of concepts of sound and light; (2) their level of knowledge of those concepts examined in terms of depth, interconnectedness, organization and understanding of importance of underlying concepts; (3) their individual classroom inquiry style (CIS) described in terms of eight emergent aspects and representing consistencies over multiple lessons in the way each participant implemented classroom inquiry for teaching science concepts; and (4) their orientations toward teaching science (OTS). Key findings indicate (1) the majority of problematic events exhibited by each participant involved choosing and implementing important learning goals; (2) using emergent aspects of CIS to analyze teaching allowed differentiation among the three participants' very similar inquiry-based teaching; (3) patterns of clustering of aspects revealed interrelationships among them; (4) limitations in SCK could account for all of the observed problematic events, however CIS provided alternative and often more plausible explanations, contradicting current literature ascribing limitations in conversationally risky practice to limitations in SCK; (5) Certain aspects of CIS were more consistently associated with SCK, while other aspects were more closely linked to participants' OTS. Implications of the study include: (1) the importance of including emergent aspects of CIS when analyzing inquiry-based teaching; (2) CIS as a new level to include when investigating the relationship between SCK and inquiry-based teaching practice; (3) the value of CIS as a tool for developing individual trajectories for enhancing preservice and inservice elementary teachers' inquiry-based teaching; and (4) the need for specialized content courses for preservice and inservice elementary teachers integrating content learning, curricular vision and general science teaching strategies.

Using inquiry-based instructional strategies in third-grade science  

Science.gov (United States)

The purpose of the study was to determine if the use of inquiry-based instructional strategies as compared to traditional instructional strategies would increase third-grade students' achievement in science, based on the pretest/posttest of the school system and the Georgia Criterion-Referenced Competency Test (CRCT). Inquiry-based instruction, presented students with a question, an observation, a data set, or a hypothesis for problem solving such as scientists use when working in real-world situations. This descriptive research employed a quantitative strategy using a pretest/posttest control group design. The research compared the science academic achievement levels of one Grade 3 class [N=14] exposed to a teacher's inquiry-based instructional strategies as compared to one Grade 3 class [ N=18] exposed to a teacher's traditional instructional strategies. The study compared the science academic performance levels of third-grade students as measured by pretest/posttest mean scores from the school system-based assessment and the Georgia CRCT. Four research hypotheses were examined. Based on the overall findings from this study, both the experimental group and the control group significantly increased their mean scores from the pretests to the posttests. The amount of gain from the pretest to the posttest was significantly greater for the experimental group than the control group for pretest/posttest 1 [t(12) = 8.79, p sciences test [t(27) = -1.95, p = .06]. Finally, the control group did not outperform the experimental group on any of the comparisons made throughout this study. The results of this study provide empirical support for the effectiveness of the use of inquiry-based learning strategies, given that the experimental group outperformed the control group on all four posttests, on the science CRCT and on the individual Science portions on the test including earth, life and physical sciences. In fact, this study was able to detect significant differences between the experimental group and the control group with regard to the degree to which the students improved from the pretests to the posttests.

Comprehensive Healthcare module: medical and pharmacy students’ shared learning experiences  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: The Comprehensive Healthcare (CHC module was developed to introduce pre-clinical medical and pharmacy students to the concept of comprehensive healthcare. This study aims to explore their shared learning experiences within this module. Methodology: During this module, medical and pharmacy students conducted visits to patients’ homes and to related community-based organisations in small groups. They were required to write a reflective journal on their experiences regarding working with other professions as part of their module assessment. Highly scored reflective journals written by students from the 2011/2012 academic session were selected for analysis. Their shared learning experiences were identified via thematic analysis. We also analysed students’ feedback regarding the module. Results: Analysis of 25 selected reflective journals revealed several important themes: ‘Understanding of impact of illness and its relation to holistic care’, ‘Awareness of the role of various healthcare professions’ and ‘Generic or soft skills for inter-professional collaboration’. Although the primary objective of the module was to expose students to comprehensive healthcare, the students learnt skills required for future collaborative practice from their experiences. Discussion: The CHC module provided early clinical exposure to community-based health issues and incorporated some elements of inter-professional education. The students learnt about the roles of other healthcare professions and acquired soft skills required for future collaborative practice during this module.

Do science coaches promote inquiry-based instruction in the elementary science classroom?  

Science.gov (United States)

The South Carolina Mathematics and Science Coaching Initiative established a school-based science coaching model that was effective in improving instruction by increasing the level of inquiry-based instruction in elementary science classrooms. Classroom learning environment data from both teacher groups indicated considerable differences in the quality of inquiry instruction for those classrooms of teachers supported by a science coach. All essential features of inquiry were demonstrated more frequently and at a higher level of open-ended inquiry in classrooms with the support of a science coach than were demonstrated in classrooms without a science coach. However, from teacher observations and interviews, it was determined that elementary schoolteacher practice of having students evaluate conclusions and connect them to current scientific knowledge was often neglected. Teachers with support of a science coach reported changes in inquiry-based instruction that were statistically significant. This mixed ethnographic study also suggested that the Mathematics and Science Coaching Initiative Theory of Action for Instructional Improvement was an effective model when examining the work of science coaches. All components of effective school infrastructure were positively impacted by a variety of science coaching strategies intended to promote inquiry. Professional development for competent teachers, implementation of researched-based curriculum, and instructional materials support were areas highly impacted by the work of science coaches.

The Cooperative Learning Effects on English Reading Comprehension and Learning Motivation of EFL Freshmen  

Directory of Open Access Journals (Sweden)

Full Text Available This experimental study aims to investigate the effects of using cooperative learning to enhance the English reading comprehension and learning motivation of EFL freshmen by comparing the cooperative learning instruction and traditional lecture instruction. This experiment was implemented in a Freshman English Reading course, a two credit course, with two hours of instruction per week, over a full semester. Seventy-eight EFL freshmen taking Freshman English Reading courses participated in this study, with 44 participants in the experimental group and 34 in the comparison group. We employed a pretest-posttest comparison group quasi-experimental design. The experimental group received a reciprocal cooperative learning instruction, whereas the comparison group received a traditional lecture instruction. Both groups were administered three English-reading achievement tests and an English learning motivation scale. The data were analyzed by means, standard deviations, t tests, and one-way ANCOVA. The findings indicate statistically significant differences in favor of cooperative learning instruction on English reading comprehension, particularly among medium- and low-proficiency students. Cooperative learning instruction also created a significantly positive effect on student motivation toward learning English reading. In conclusion, we strongly suggest teachers use cooperative learning instruction in university-level EFL reading classes.

A self-study of designing and implementing an inquiry-based chemistry course for elementary education majors  

Science.gov (United States)

This self-study examines my experiences with implementing an inquiry-based version of a chemistry course (Chemistry 299) designed for elementary education majors. The inquiry-based curriculum design and teaching strategies that I implement in Chemistry 299 is the focus of this study. Since my previous education and professional experiences were in the physical sciences, I position myself in this study as a scientist who engages in self-study as a form of professional development for the purpose of developing an inquiry-based curriculum and instructional practices. My research provides an inside perspective of the curriculum development process. This process involves implementing the inquiry-oriented ideas and knowledge I acquired in my graduate studies to design the curriculum and influence my teaching practice. My analysis of the curriculum and my instruction is guided by two questions: What are the strengths and weaknesses of the inquiry-based Chemistry 299 curriculum design? What does the process of developing my inquiry-based teaching practice entail and what makes is challenging? Schwab's (1973) The Practical 3: Translation into Curriculum serves as the theoretical framework for this study because of the emphasis Schwab places on combining theoretical and practical knowledge in the curriculum development process and because of the way he characterizes the curriculum. The findings in this study are separated into curriculum and instruction domains. First, the Chemistry 299 curriculum was designed to make the epistemological practices of scientists "accessible" to students by emphasizing epistemic development with respect to their ideas about scientific inquiry and science learning. Using student learning as a gauge for progress, I identify specific design elements that developed transferable inquiry skills as a means to support scientific literacy and pre-service teacher education. Second, the instruction-related findings built upon the insight I gained through my analysis of the curriculum. The data reveals four areas of inner conflict I dealt with throughout the study that related to underlying beliefs I held about science teaching and learning. The implications of the study position the Chemistry 299 curriculum in the field and speak to issues related to developing science courses for elementary education majors and professional development for scientists.

Aligning the Hidden Curriculum of Management Education With PRME : An Inquiry-Based Framework  

DEFF Research Database (Denmark)

This article argues that mainstreaming responsible management education in line with the Principles of Responsible Management Education (PRME) requires close attention to the hidden curriculum (HC), that is, the implicit dimensions of educational experiences. Altering formal curricular goals and content alone is not enough to improve students’ sense of social responsibility. Business schools are conceptualized in this article as multilevel learning environments comprising various message sites where students undergo moral learning and socialization processes. Using perspectives from HC research combined with transformative learning and communities of practice theory, the article offers an inquiry-based framework for PRME implementation that takes these moral learning and socialization processes into account. It provides suggestions for how to address the hidden curriculum both in the diagnostic phase of assessing a school’s PRME needs and in the implementation phase where PRME is integrated into business school learning environments. The concept of meta-messages is introduced to account for how students apprehend the HC at business schools.

This study involved three teachers in various stages of implementation of inquiry-based science method. The cases were chosen because one participant was a novice in using inquiry-based science method, one participant was in her second year of implementation, and the third participant was experienced with inquiry-based science method. The cases were set in a rural high school in three different science classrooms. One of the classrooms was a regular biology class. One of the classrooms was an honors oceanography class and another was an advanced placement environmental science classroom. Data sources included interviews, observations, and document collection. Interviews, observations, and document collection were used to triangulate data. Each classroom was observed five times. Interviews were conducted at the beginning of the semester with each participant and at the end of the semester. Follow-up interviews were conducted after each observation. Documents were collected such as each teacher's lesson plans, student work, and assignments. Data was initially organized according to the research areas of teacher's definition, teacher's beliefs, teacher's barriers to implementation, and teacher's enablers to implementation. Then, patterns emerging from each of these cases were organized. Lastly, patterns emerging across cases were compared in a cross-case analysis. Patterns shared between cases were: Participants related inquiry-based science method with hands-on learning activities. Participants saw students as the center of the learning process. Participants had positive beliefs about constructivist learning practices that were strengthened after implementation of inquiry-based teaching. Facilitators of successful implementation of inquiry-based science method were positive student motivation, students' retention of knowledge, and a positive experience for lower level students. Barriers to successful implementation were teachers not having complete control of the classroom, upper level students having difficulty with inquiry, time and curriculum being a factor, and teachers feeling unprepared to teach this methodology. The researcher culminated the study with practice and policy implications and reasons for further research. Overall, the findings were that these teachers in various stages of implementation with little training in this methodology were able to successfully implement inquiry-based science method based on the reform movement's definition despite barriers to implementation.

Guided-inquiry based laboratory instruction: Investigation of critical thinking skills, problem solving skills, and implementing student roles in chemistry  

Science.gov (United States)

Recent initiatives in the laboratory curriculum have encouraged an inquiry-based approach to learning and teaching in the laboratory. It has been argued that laboratory instruction should not just be hands-on, but it should portray the essence of inquiry through the process of experiential learning and reflective engagement in collaboration with peers and in facilitation by the instructor. A student-centered active learning approach may be an effective way to enhance student understanding of concepts in the laboratory. The dissertation research work explores the impact of laboratory instruction and its relevance for college-level chemistry. Each chapter is different from the preceding chapter in terms of the purpose of the study and the research questions asked. However, the overarching idea is to address the importance of guided-inquiry based laboratory instruction in chemistry and its relevance in helping students to make connections with the chemistry content and in imparting skills to students. Such skills include problem solving, collaborative group work and critical thinking. The first research study (Chapter 2) concerns the impact of first year co-requisite general chemistry laboratory instruction on the problem-solving skills of students. The second research study (Chapter 3) examines the impact of implementing student roles also known as Student-Led Instructor Facilitated Guided-Inquiry based Laboratories, SLIFGIL) by modifying the Science Writing Heuristic approach of laboratory instruction. In the third research study (Chapter 4), critical thinking skills of first semester general chemistry laboratory students were compared to advanced (third or fourth year) chemistry laboratory students based on the analysis of their laboratory reports.

Students As Researchers In An Inquiry Based Classroom  

Science.gov (United States)

A teacher who participated in the National Science Foundation supported ARMADA Project through the University of Rhode Island Office of Marine Programs will share a series of lessons based on her experiences working with marine researchers. All of the activities are hands-on, inquiry based for use in elementary and secondary classrooms. The primary objective of these lessons is to give students a better understanding of what real scientist do and why. This enables students to make a real world connection with the scientific community. The emphasis on environmental monitoring will help develop an understanding of the positive and negative consequences of human action on the Earth's oceans. It will enhance the student's observation skills and increase their ability to record and analyze data.

Ocean Science in a K-12 setting: Promoting Inquiry Based Science though Graduate Student and Teacher Collaboration  

Science.gov (United States)

The University of South Florida, College of Marine Science Oceans: GK-12 Teaching Fellowship Program is successfully enriching science learning via the oceans. Funded by the National Science Foundation, the program provides a unique opportunity among scientists and K-12 teachers to interact with the intention of bringing ocean science concepts and research to the classroom environment enhance the experience of learning and doing science, and to promote `citizen scientists' for the 21st century. The success of the program relies heavily on the extensive summer training program where graduate students develop teaching skills, create inquiry based science activities for a summer Oceanography Camp for Girls program and build a relationship with their mentor teacher. For the last year and a half, two graduate students from the College of Marine Science have worked in cooperation with teachers from the Pinellas county School District, Southside Fundamental Middle School. Successful lesson plans brought into a 6th grade Earth Science classroom include Weather and climate: Global warming, The Geologic timescale: It's all about time, Density: Layering liquids, and Erosion processes: What moves water and sediment. The school and students have benefited greatly from the program experiencing hands-on inquiry based science and the establishment of an after school science club providing opportunities for students to work on their science fair projects and pursuit other science interests. Students are provided scoring rubrics and their progress is creatively assessed through KWL worksheets, concept maps, surveys, oral one on one and classroom discussions and writing samples. The year culminated with a series of hands on lessons at the nearby beach, where students demonstrated their mastery of skills through practical application. Benefits to the graduate student include improved communication of current science research to a diverse audience, a better understanding of the perspective of teachers and their content knowledge, and experience working with children and youth. The GK-12 teacher mentor benefits include a resource of inquiry based ocean science activities and increased knowledge of current scientific ocean research. The K-12 students gain an opportunity to be engage with young passionate scientists, learn about current ocean science research, and experience inquiry based science activities relating to concepts already being taught in their classroom. This program benefits all involved including the graduate students, the teachers, the K-12 students and the community.

Inquiry-Based Early Undergraduate Research Using High-Altitude Ballooning  

Science.gov (United States)

One common objective for undergraduate science classes is to have students learn how to do scientific inquiry. However, often in science laboratory classes, students learn to take data, analyze the data, and come to conclusions, but they are told what to study and do not have the opportunity to ask their own research questions, a crucial part of scientific inquiry. A special topics class in high-altitude ballooning (HAB) was offered at Metropolitan Community College, a large metropolitan two-year college in Omaha, Nebraska to focus on scientific inquiry for the participants through support of NASA Nebraska Space Grant. A weather balloon with payloads attached (balloonSAT) was launched to near space where the balloon burst and fell back to the ground with a parachute. Students worked in small groups to ask their research questions, they designed their payloads, participated in the launch and retrieval of equipment, analyzed data, and presented the results of their research. This type of experience has potential uses in physics, physical science, engineering, electronics, computer programming, meteorology, astronomy, and chemistry classes. The balloonSAT experience can act as a stepping-stone to designing sounding rocket payloads and it can allow students the opportunity to participate in regional competitions and present at HAB conferences. Results from the workshop are shared, as well as student responses to the experience and suggestions for administering a high-altitude ballooning program for undergraduates or extending inquiry-based ballooning experiences into high-school or middle-school.

Implementation of Inquiry-Based Tutorials in AN Introductory Physics Course: the Role of the Graduate Teaching Assistant.  

Science.gov (United States)

This study determined if the training provided physics teaching assistants was sufficient to accomplish the objectives of inquiry-based tutorials for an introductory physics course. Qualitative research methods were used: (1) to determine if the Physics by Inquiry method was modeled; (2) to describe the process from the teaching assistant perspective; (3) to determine TA opinions on training methods; (4) to develop a frame of reference to better understand the role of TA's as instructional support staff. The study determined that the teaching assistants verbalized appropriate instructional actions, but were observed to use a predominantly didactic teaching style. TA's held a variety of perceptions and beliefs about inquiry -based learning and how science is learned. They felt comfortable in the role of tutorial instructor. They were satisfied with the training methods provided and had few suggestions to change or improve training for future tutorial instructors. A concurrent theme of teacher action dependent on teacher beliefs was sustained throughout the study. The TA's actions, as tutorial instructors, reflected their educational beliefs, student background and learning experiences. TA's performance as tutorial instructors depended on what they think and believe about learning science. Practical implications exist for training teaching assistants to be tutorial instructors. Some recommendations may be appropriate for TA's required to use instructional methods that they have not experienced as students. Interview prospective teaching assistants to determine educational experience and beliefs. Employ inexperienced teaching assistants whose perspectives match the proposed instructional role and who might be more receptive to modeling. Incorporate training into staff meetings. Provide time for TA's to experience the instructional model with simulation or role play as students and as instructors, accompanied by conference discussion. Use strategies known to enhance adult learning and that are sensitive to the variability of adult learners. Educate for critical reflection; incorporate a system of peer coaching. Include a teaching assistant training component in group process and group management.

The Impact of Two Types of Vocabulary Preparation on Listening Comprehension, Vocabulary Learning, and Vocabulary Learning Strategy Use  

Directory of Open Access Journals (Sweden)

Full Text Available Considering previous studies of the impact of vocabulary preparation before listening comprehension, this research investigated the impact of oral and written pushed output as two types of vocabulary preparation on listening comprehension, active and passive vocabulary learning, and vocabulary learning strategy use. Forty-one female adult Iranian EFL students at intermediate level participated in this study. As a treatment, they received two lists of new words which were learned separately through oral and written pushed output. This was followed by tests of active and passive vocabulary and listening comprehension. They also completed a vocabulary learning questionnaire before and after the treatment to detect any changes due to the treatment. We reached three pairs of scores for each participant including two active and two passive vocabulary test scores and two listening test scores for words treated through oral and written pushed output, separately. Statistical analyses indicated that vocabulary learning through oral pushed output was more effective in promoting listening comprehension and active vocabulary learning than vocabulary learning through written pushed output. Generally, vocabulary leaning through pushed output had a positive significant effect on vocabulary leaning strategy use. However, regarding passive vocabulary learning, the two types of treatment did not make any significant difference.

The ERESE Project: Modeling Inquiry-Based Plate Tectonic Lessons  

Science.gov (United States)

The Enduring Resources for Earth Science Education (ERESE) project is a collaborative effort between earth scientists, educators, librarians and data archive managers. Its goal is to develop and maintain a persistent online research and education archive in a digital library environment that supports earth science education in plate tectonics. A key to the library's effectiveness as an educational tool is the efficiency with which educators can access, use and contribute to the library. We have created a master template that educators use to develop inquiry-based curriculum. The central components of the master template include a teacher log, a student log and resource matrices. The teacher's log is divided into stages that reflect our approach to inquiry. This approach was used during a workshop as scientists worked with the teachers to model a reasonable pedagogical analog to scientific inquiry. The student log is similar in structure to a scientific method lab report. There are currently 17 resource matrices that directly access canonical education objects in the digital library, 3 of which relate to expedition planning and 14 to plate tectonics. The structure of the resource matrices allows teachers and students to traverse manageable packets of information relating to a specific topic by expert level (rows) and information type (columns). Teachers download and customize the master template using any web composer and are then invited to upload their lessons through a simple interface at Earthref.org. Once uploaded the lessons become part of the ERESE digital library collection. The upload process allows teachers to define keywords and metadata to allow useful searches by topic, concept or educational standard. The use of a single master template for inquiry lesson design means library contributions will share a common format as well as exploit identical plate tectonic resources.

ACTIVE STRATEGIES DURING INQUIRY-BASED SCIENCE TEACHER EDUCATION TO IMPROVE LONG-TERM TEACHER SELF-EFFICACY  

DEFF Research Database (Denmark)

Teacher development aimed at increasing the use of inquiry based methods in schools is an important way to reach science learning goals. To this end, the EC has promoted inquiry based science teaching (IBST) within the Seventh Framework Program (FP7). One dimension, typically absent from the FP7 products, is the personal capacity belief of self- efficacy which has been shown to be important to personal behavioral change. The purpose of this research was to develop and test a model of teacher professional development (TPD) which adds specific elements for altering teacher self-efficacies to existing FP7 IBST products. This model was tested for its usefulness in increasing participant self-efficacy as evidenced by short and long term quantitative measures as well as by evaluation of long terminquiry lessons. Workshops to promote IBST were conducted in five different countries. Each workshop included strategies for increasing participant’s self-efficacies. Pre and post assessments showed consistently improved personal self-efficacy scores in all of the workshops. In addition, and unlike other long-term studies of teachers, these self-efficacy scores did not significantly diminish over six months. The promotion of self-efficacy in TPD provides a consistent way of evaluating the impact of IBST workshops through the use of changes in self-efficacy.

Achieving science, math and reading literacy for all: The role of inquiry-based science instruction  

Science.gov (United States)

With the enactment of the No Child Left Behind Act of 2001, educators and policy makers have been seeking effective strategies to improve students' science, mathematics and reading achievement. One of the primary teaching strategies recommended by reform-oriented organizations, such as the National Research Council (1996), is to utilize inquiry-based science instruction. In this study, I examined the effects of inquiry-based science instruction and traditional science instruction on student achievement across science, mathematics and reading. I also compared the effects of inquiry-based science instruction and traditional science instruction on student achievement. Using data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999---a large, national data sample---a series of structural equation modeling analyses were performed. Results indicated that inquiry-based science instruction was associated with significant, positive gains not only in science achievement, but also in mathematics and reading achievement. The positive relationship between inquiry instruction and student achievement was found above and beyond the contributions of traditional science instruction, which generally showed no significant relationship to student achievement. Findings support the theoretical position that inquiry-based science instruction can have robust benefits across the curriculum. This study contributes to the dialogue on effective instructional methods to achieve science, mathematics and reading literacy for all. Overall, this study provides cautious support for the idea that student achievement can be promoted by supporting and encouraging teachers to implement inquiry-based science instruction.

Graduate Student and High School Teacher Partnerships Implementing Inquiry-Based Lessons in Earth Science  

Science.gov (United States)

Partnering science graduate students with high school teachers in their classroom is a mutually beneficial relationship. Graduate students who may become future university level faculty are exposed to teaching, classroom management, outreach scholarship, and managing time between teaching and research. Teachers benefit by having ready access to knowledgeable scientists, a link to university resources, and an additional adult in the classroom. Partnerships in Research Opportunities to Benefit Education (PROBE), a recent NSF funded GK-12 initiative, formed partnerships between science and math graduate students from the University of New Hampshire (UNH) and local high school science teachers. A primary goal of this program was to promote inquiry-based science lessons. The teacher-graduate student teams worked together approximately twenty hours per week on researching, preparing, and implementing new lessons and supervising student-led projects. Several new inquiry-based activities in Geology and Astronomy were developed as a result of collaboration between an Earth Science graduate student and high school teacher. For example, a "fishbowl" activity was very successful in sparking a classroom discussion about how minerals are used in industrial materials. The class then went on to research how to make their own paint using minerals. This activity provided a capstone project at the end of the unit about minerals, and made real world connections to the subject. A more involved geology lesson was developed focusing on the currently popular interest in forensics. Students were assigned with researching how geology can play an important part in solving a crime. When they understood the role of geologic concepts within the scope of the forensic world, they used techniques to solve their own "crime". Astronomy students were responsible for hosting and teaching middle school students about constellations, using a star- finder, and operating an interactive planetarium computer program. In order to successfully convey this information to the younger students, the high school students had to learn their material well. This model of pairing graduate students with science teachers is continuing as a component of the Transforming Earth System Science Education (TESSE) program.

Investigating elementary education and physical therapy majors' perceptions of an inquiry-based physics content course  

Science.gov (United States)

This study investigates why physical therapy assistant majors engage and perform better than elementary education majors in an inquiry-based conceptual physics course at Mid-Atlantic Community College. The students from each major are demographically similar, both courses are similar in depth and structure, and each course supports the students' program. However, there is an observed difference in the levels of engagement with the curriculum and performance on writing-based assessments between the two groups. To explore possible explanations for the difference, I examine students' affinity for science, their beliefs about the nature of science and scientific knowledge in the classroom, and their perception of the usefulness of science to their program. During semi-structured interviews, students from both majors displayed nearly identical weak affinities for science, epistemological beliefs, and uncertainty about the usefulness of the class. However, the physical therapy majors' ability to see the relevance of the physics course experience to their program enhanced their interest and motivation. In contrast, the elementary education students do not see connections between the course and their program, and do not see a purpose for their learning of physics content. To improve the program, I propose a two-pronged approach - designing a faded-scaffolded-inquiry approach for both classes, and developing a field-based/seminar class for the elementary education majors. The scaffolded inquiry will help both groups develop better orientations toward lab activities, and the structured observations and reflection will help the elementary group connect the material to their program.

Girls on Ice: An Inquiry-Based Wilderness Science Education Program  

Science.gov (United States)

We developed a wilderness science education program for high school girls. The program offers opportunities for students to explore and learn about mountain glaciers and the alpine landscape through scientific field studies with geologists and glaciologists. Our purpose is to give students a feeling for the natural processes that create the alpine world and provide an environment that fosters the critical thinking necessary to all scientific inquiry. The program is currently being offered through the North Cascades Institute, a non-profit organization offering outdoor education programs for the general public. We lead eight girls for a weeklong expedition to the remote USGS South Cascade Glacier Research Station in Washington's North Cascades. For four days, we explore the glacier and the nearby alpine valleys. We encourage the girls to observe and think like scientists through making observations and inferences. They develop their own experiments to test ideas about glacier dynamics and geomorphology. In addition to scientific exploration, we engage the students in discussions about the philosophy of science and its role in our everyday lives. Our program exemplifies the success of hands-on, inquiry-based teaching in small groups for science education in the outdoors. The wilderness setting and single gender field team inspires young women's interest in science and provides a challenging environment that increases their physical and intellectual self-confidence.

The Development of an Inquiry-based Curriculum Specifically for the Introductory Algebra-based Physics Course  

CERN Document Server

We discuss an inquiry-based curriculum that has been developed specifically for the introductory algebra-based physics course, taking into account the needs, backgrounds, learning styles and career goals of the students in that class. The course is designed to be taught in a laboratory-based environment, however parts of the materials can be used in other settings. As instructors we found ourselves drawing on materials developed for the calculus-based course and for other populations (materials developed for pre-service teachers, for example), parts of which were appropriate, but not a complete curriculum as we would like to teach it, developed specifically for students in the introductory algebra-based physics course. So we have modified and adapted parts of existing materials and integrated them with our own new units and our own format, creating a course aimed specifically at these students.

This study investigated whether any of the conditions promoted noticing and whether this noticing led to better comprehension of the text and learning of the target vocabulary words. Reading comprehension, recognition, and production measures were utilized in a pre-post test design. Results of quantitative and qualitative analyses of the data gathered showed first that all multimedia gloss groups noticed and recognized significantly more of the target words than the control group. Second, no significant differences were found among any of the groups in production of the target vocabulary items. Finally, regarding comprehension, results showed that the combination gloss group significantly outperformed all other groups. These results confirm that the multimedia glosses under investigation have a different effect on comprehension and vocabulary learning respectively.

A phenomenological study of assessment methods in the inquiry-based science classroom: How do educators decide?  

Science.gov (United States)

The purpose of this phenomenological study was to describe the experiences of science educators as they select and develop assessment methods for inquiry learning. Balancing preparations for standardized tests and authentic inquiry assessment experiences can be challenging for science educators. The review of literature revealed that current research focused on instructional methods and assessment, students' assessment experiences, and teachers' instructional methods experiences. There remains a gap in current literature regarding the experiences of science educators as they select and develop assessment methods for inquiry learning. This study filled the gap by providing a description of the experiences of science educators as they select and develop assessments for inquiry learning. The participants in this study were 16 fifth through eighth grade science teachers who participate in the Alabama Math, Science, and Technology Initiative (AMSTI) in northwest Alabama. A phenomenological research method was chosen in order to describe the experiences of AMSTI science teachers as they select and develop assessments for inquiry learning. Data were collected through interviews and focus group discussions. The data analysis used a modified Stevick-Colaizzi-Keen framework. The results showed AMSTI science teachers use a variety of assessment resources and methods, feel pressures to meet Adequate Yearly Progress (AYP), and implement varying degrees of change in their assessment process due to No Child Left Behind (NCLB). Contributing a positive social change, this study's findings supplied science teachers with descriptions of successful inquiry classrooms and creative assessments that correspond to inquiry-based learning methods.

Argumentation and Equity in Inquiry-Based Science Instruction: Reasoning Patterns of Teachers and Students  

Science.gov (United States)

This multiple case study explores issues of equity in science education through an examination of how teachers' reasoning patterns compare with students' reasoning patterns during inquiry-based lessons. It also examines the ways in which teachers utilize students' cultural and linguistic resources, or funds of knowledge, during inquiry-based lessons and the ways in which students utilize their funds of knowledge, during inquiry-based lessons. Three middle school teachers and a total of 57 middle school students participated in this study. The data collection involved classroom observations and multiple interviews with each of the teachers individually and with small groups of students. The findings indicate that the students are capable of far more complex reasoning than what was elicited by the lessons observed or what was modeled and expected by the teachers, but that during the inquiry-based lessons they conformed to the more simplistic reasoning patterns they perceived as the expected norm of classroom dialogue. The findings also indicate that the students possess funds of knowledge that are relevant to science topics, but very seldom use these funds in the context of their inquiry-based lessons. In addition, the teachers in this study very seldom worked to elicit students' use of their funds in these contexts. The few attempts they did make involved the use of analogies, examples, or questions. The findings from this study have implications for both teachers and teacher educators in that they highlight similarities and differences in reasoning that can help teachers establish instructional congruence and facilitate more equitable science instruction. They also provide insight into how students' cultural and linguistic resources are utilized during inquiry-based science lessons.

The Intersection of Inquiry-Based Science and Language: Preparing Teachers for ELL Classrooms  

Science.gov (United States)

As teacher educators, we are tasked with preparing prospective teachers to enter a field that has undergone significant changes in student population and policy since we were K-12 teachers. With the emphasis placed on connections, mathematics integration, and communication by the New Generation Science Standards (NGSS) (Achieve in Next generation science standards, 2012), more research is needed on how teachers can accomplish this integration (Bunch in Rev Res Educ 37:298-341, 2013; Lee et al. in Educ Res 42(4):223-233, 2013). Science teacher educators, in response to the NGSS, recognize that it is necessary for pre-service and in-service teachers to know more about how instructional strategies in language and science can complement one another. Our purpose in this study was to explore a model of integration that can be used in classrooms. To do this, we examined the change in science content knowledge and academic vocabulary for English language learners (ELLs) as they engaged in inquiry-based science experience utilizing the 5R Instructional Model. Two units, erosion and wind turbines, were developed using the 5R Instructional Model and taught during two different years in a summer school program for ELLs. We analyzed data from interviews to assess change in conceptual understanding and science academic vocabulary over the 60 h of instruction. The statistics show a clear trend of growth supporting our claim that ELLs did construct more sophisticated understanding of the topics and use more language to communicate their knowledge. As science teacher educators seek ways to prepare elementary teachers to help preK-12 students to learn science and develop the language of science, the 5R Instructional Model is one pathway.

Teacher enactment of an inquiry-based science curriculum and its relationship to student interest and achievement in science  

Science.gov (United States)

This mixed-methods case study, influenced by aspects of grounded theory, aims to explore the relationships among a teacher's attitude toward inquiry-based middle school reform, their enactment of such a curriculum, and student interest and achievement in science. A solid theoretical basis was constructed from the literature on the benefits of inquiry-based science over traditional science education, the benefits of using constructivist learning techniques in the classroom, the importance of motivating teachers to change their teaching practices to be more constructive, and the importance of motivating and exciting students in order to boost achievement in science. Data was collected using qualitative documents such as teacher and student interviews, classroom observations, and curriculum development meetings, in addition to quantitative documents such as student science interest surveys and science skills tests. The qualitative analysis focused on examining teacher attitudes toward curricular reform efforts, and the enactments of three science teachers during the initial year of an inquiry-based middle school curriculum adoption using a fidelity of implementation tool constructed from themes that emerged from the data documents utilized in this study. In addition, both qualitative and quantitative tools were used to measure an increase or decrease in student interest and student achievement over the study year, and their resulting relationships to their teachers' attitudes and enactments of the curriculum. Results from data analysis revealed a positive relationship between the teachers' attitude toward curricular change and their fidelity of implementation to the developers' intentions, or curricular enactment. In addition, strong positive relationships were also discovered among teacher attitude, student interest, and student achievement. Variations in teacher enactment also related to variations in student interest and achievement, with considerable positive relationships among the factors compared. The results of this study demonstrate that teachers' attitudes must be taken into account for science reform to be successful because they impact not only their implementation but also students' attitudes and achievement. Implications for future research include promoting the use of similar qualitative tools to monitor factors such as teacher enactment in order to identify potential roadblocks to curricular change and encourage student interest and achievement in the classroom.

Self Regulated Learning strategies as Predictors of Reading Comprehension among Students of English as a Foreign Language  

Directory of Open Access Journals (Sweden)

Full Text Available This cross-sectional study investigates the self regulated learning strategies used as predictors of reading comprehension. Participants of the study were 248 EFL university students: 112 males and 136 females enrolled in the Faculty of Arts, Foreign Languages Department. The primary aims of the study were: (1 to examine whether there were positive relationships between the use of self regulated learning strategies and reading comprehension; (2 whether there were significant differences between males and females in use of self regulated learning strategies and reading comprehension; (3 and finally to gauge predictors of reading comprehension themselves through self regulated learning strategies towards learning English language. Students were asked to answer questions based on a 5-point Likert-scale self regulated learning Questionnaire and they were asked to read three different passages and answer the questions that followed each passage. The results of MANOVA also revealed that there were differences between males and females in the use of self regulated learning strategies in favour of females. However, there were differences between males and females in the reading comprehension test to the advantage of males. The results of MANOVA analysis revealed that there were differences between students across their different academic levels in self regulated learning strategies. There were also differences between students across different academic levels, in the reading comprehension test. The results of multiple regression reported that some of the self-regulated learning strategies were predictors of reading comprehension.

Sustainability in a state comprehensive cancer control coalition: lessons learned.  

Science.gov (United States)

The Alabama Comprehensive Cancer Control Coalition (ACCCC) has developed an integrated and coordinated approach to reducing cancer incidence, morbidity, and mortality, and to improving the quality of life for cancer survivors, their families, and their caregivers. The ACCCC is currently in a maintenance phase and a formal plan for sustainability of the coalition was needed to keep the members engaged and productive. A training session in coalition sustainability conducted in 2013 identified the following elements as essential to success: (1) increased marketing of the coalition by simplifying its mission; (2) improved networking including flexibility in coalition meeting location and attendance; (3) increased membership satisfaction through transformational leadership; (4) revision of the working structure of committees and improved accountability; and (5) enhancement of partner satisfaction with coalition activities designed to recruit and retain new partners. A self-administered membership satisfaction survey was given to assess coalition mission, meeting logistics, organization, capacity building, and coalition goals. Results indicated that the subcategories of communication, mission, and meeting logistics were rated satisfied to very satisfied on a five-point scale. Although the ACCCC had clearly written goals, improvement could be made in leadership participation and new member orientation could be improved. Most members rated their parent organization as highly involved with the ACCCC and many offered suggestions on capacity building. Results of the sustainability training have clarified the ACCCC's plans to ensure coalition viability and improve strategies to inform stakeholders of the benefits of participation in the coalition.

Engineering Your Own Superbug: A Useful Assignment to Evaluate Real Learning Comprehension in Microbiology Classes  

Directory of Open Access Journals (Sweden)

Full Text Available The learning comprehension of students in microbiology classes is not easy to evaluate, particularly when the student population is diverse in terms of backgrounds, majors, levels of training and preparedness, and the students’ expectations and enthusiasm for the class. It is difficult to design a one-size-fits-all exam that best suits a mixed student population; and most traditional assignments/case studies focusing on particular microbes or topics might not readily assess students’ overall understanding and learning comprehension. It is important to develop an assessment method that not only can engage students in active learning and deliberate practice but can also promote their imaginative and creative potential. The word “superbugs” often appears in the media and refers to some deadly or drug-resistant microbes. These superbugs possess special phenotypic and functional attributes that constitute their “superness.” It is predicted that more new surprising superbugs will emerge in the future and students should be challenged now with some mindstimulating ideas and exercises in their microbiology class. To develop a supplementary tool to evaluate students’ comprehension and to prepare them for the predicted superbugs unknown to us, a writing project entitled “Constructing Your Own Superbug” was designed to achieve these goals.

DIDACTICAL AND METHODOLOGICAL SPECIFIC FEATURES OF THE APPLICATION OF LABORATORY-EXPERIMENTAL METHOD AND INQUIRY-BASED APPROACH TO TEACHING SCIENCE AND NATURE  

Directory of Open Access Journals (Sweden)

Full Text Available Students should be instructed in the ways in which scientific truths are reached as early as possible, so that they are able to grasp the complex system of knowledge about the natural and social environment. Their innate curiosity and the need to explore and study the world around them should be nourished and encouraged while Science lessons should include such teaching methods and strategies that provide opportunities for discovering, problem solving, experimenting, constructive and critical analysis, contemplation and interpreting certain phenomena and processes. Teaching Science in a classroom in which students are sitting properly while listening attentively to the teacher and memorizing the facts and information the teacher is presenting is considered traditional and it cannot meet the needs and challenges of the modern society. By using the laboratory-experimental method and inquiry-based approach that is theoretically grounded in today?s widely accepted constructivist educational paradigm, Science lessons could become more modern, innovative and more intense. Being engaged in the activities generated from the inquiry-based method makes students more independent, helps them boost their self-confidence and also enables them to acquire knowledge in different ways. At the core of the scientific method is the view that knowledge must come as a consequence of personal observation, practical action and thinking, whereas learning is seen as finding and discovering. The paper emphasizes the structure, didactical and methodological specific features and the organisation of Science and Nature classes by using the laboratory-experimental method and inquiry-based approach, the consequences of its inadequate and insufficient application and lists the contents of the subjects The world around us/ Science and Nature that we consider appropriate for the application of this teaching strategy.

Contributions of Metacognitive and Self-Regulated Learning Theories to Investigations of Calibration of Comprehension  

Directory of Open Access Journals (Sweden)

Full Text Available In this paper we examine the contributions of metacognitive and self-regulated learning theories to research on students' calibration of comprehension. Historically, cognitive psychologists have studied calibration of comprehension within a purely metacognitive framework, with an emphasis on the role of text and task factors but little consideration of factors of self. There has been a recent trend, however, towards incorporating a social cognitive perspective to the study of calibration of comprehension, with factors of self such as motivation and affect being examined more often. Among the factors of self that have been examined, self-efficacy has played a major role as it may be all but impossible to disentangle its influence on students' calibration of comprehension. Other variables of self that have been examined include ability, familiarity, ego and goal-orientation, goal setting, personality traits and susceptibility to social and cultural influences. Broadening the context in which calibration of comprehension is assessed allows a more complete examination of the rich set of interrelated processes that affect students' performance.

Favorite Demonstration: Demonstrating Inquiry-Based Teaching Competencies in the Life Sciences: Part 1  

Science.gov (United States)

Research shows that many students hold misconceptions related to plant functions (Hershey 2004). Some of these students will become teachers with little content understanding to identify their students' misconceptions about plants (Amir and Tamir 1994). The literature on teaching about plants doesn't help; it contains frequent errors, misconceptions, and overgeneralizations, providing few reliable resources to inform teaching practices (Hershey 2004). It is within this context that the National Research Council (NRC) encourages science teachers, including those in the life sciences, to adopt inquiry-based teaching practices (1996; 2000; 2001). However, this effort is hampered by teachers' limited background knowledge about plants and a lack of appropriate inquiry-based instructional resources that focus on concepts related to plant functions. This article describes a series of activities that address each of these issues.

Inquiry-based laboratory investigations and student performance on standardized tests in biological science  

Science.gov (United States)

Achievement data from the 3rd International Mathematics and Sciences Study and Program for International Student Assessment in science have indicated that Black students from economically disadvantaged families underachieve at alarming rates in comparison to White and economically advantaged peer groups. The study site was a predominately Black, urban school district experiencing underachievement. The purpose of this correlational study was to examine the relationship between students' use of inquiry-based laboratory investigations and their performance on the Biology End of Course Test, as well as to examine the relationship while partialling out the effects of student gender. Constructivist theory formed the theoretical foundation of the study. Students' perceived levels of experience with inquiry-based laboratory investigations were measured using the Laboratory Program Variable Inventory (LPVI) survey. LPVI scores of 256 students were correlated with test scores and were examined by student gender. The Pearson correlation coefficient revealed a small direct correlation between students' experience in inquiry-based laboratory investigation classes and standardized test scores on the Biology EOCT. A partial correlational analysis indicated that the correlation remained after controlling for gender. This study may prompt a change from teacher-centered to student-centered pedagogy at the local site in order to increase academic achievement for all students. The results of this study may also influence administrators and policy makers to initiate local, state, or nationwide curricular development. A change in curriculum may promote social change as students become more competent, and more able, to succeed in life beyond secondary school.

A study of teachers' self-efficacy and outcome expectancy for science teaching throughout a science inquiry-based professional development program  

Science.gov (United States)

The goal of this study was to investigate the self-efficacies and outcome expectancies of science teachers over time as a result of their participation in an inquiry-based, professional development program designed to ensure that all participants are highly qualified science teachers. Eighty-six teachers participated in inquiry-based activities designed to increase their content knowledge and teaching expertise while increasing their science teaching self-efficacies and outcome expectancies of student learning. This 15-month professional development program included two summer workshops (summers of 2007 and 2008) with an 8-month classroom implementation period in between. A quasi-experimental research design was used to investigate the change in science teaching efficacy scores after participation in the inquiry-based professional development program and the relationship of this change with selected independent variables. The data consisted of (a) three sets of Science Teaching Efficacy Belief Instrument (Riggs & Enochs, 1990) scores, STEBI-Form A (inservice), reported as a pretest, posttest, and follow-up posttest; and (b) demographic variables that were used as covariates: science education background, professional position, number of years taught, and teacher qualification status in science. Using repeated measures and multiple regressions with an alpha level of 0.05, and testing the hypothesized changes and relationships, results indicated that there were gains in Personal Science Teaching Efficacy (PSTE) and Science Teaching Outcome Expectancy (STOE) scores. Of the independent variables, only science education background was found to be a significant contributor toward increasing PSTE (p = .003) scores. The other variables were not predictive of gains in either personal science teaching efficacy or science teaching outcome expectancy. The data gave insight into possible relationships that may exist between science teachers' self-efficacies and outcome expectancies after participation in an inquiry-based professional development program. This study demonstrated the importance of considering interactions between a given set of independent variables and self-efficacy beliefs. The findings also suggested the possible value of considering factors associated with planning long-term programs for teachers' professional development to include the impact of college courses, an implementation period for incorporating the new ideas, support from colleagues and providing professional development to become Highly Qualified Teachers of science.

THE PSYCHOLOGICAL NATURE OF TEXT COMPREHENSION IN TERMS OF TEXT LEARNING PROCESSES  

Directory of Open Access Journals (Sweden)

Full Text Available Texts are important tools for learning. Thus, the attempt to make textsmore understandable is a reflection of a purpose-function relatednecessity for learning from text. On the other hand, the idea ofdevelopment and recovery of informative texts via corrective teachingmaterials is frequently explored by contemporary researchers. Thus, it isevident that more advanced proficiency is needed for the illustratedaspect of the structure of texts in the learning process and to make theefforts to prepare educational materials at more scientific ground.Therefore, in this study textual organization and a general theory oflearning from texts are outlined and later language processing in workingmemory and related phenomena about learning from texts andindividual differences including information about texts development,texts comprehension, and inferences from texts are discussed. The reasonfor this is the idea that working memory is responsible for not onlyrecalling the stored information but also for storing the results of partialprocesses such as successive processes like language comprehension asexplained in the related literature for modern memory theories. Theother reason is the generalizations about the interaction between theprocesses of physical representation and pattern of a text manifested inaccordance with these ideas. Additionally, not only the differentprocedures used to develop informative texts, at the same time,differences of these procedures including a learner’s view of world andprocess styles and measurement of text comprehension and the complexrelations among them are the current and available information in theliterature. As a result, due to the nature of factors, which affect alearner’s level of recalling and his understanding from text, this studyaims to discuss this assumptions.

Making sense of shared sense-making in an inquiry-based science classroom: Toward a sociocultural theory of mind  

Science.gov (United States)

Despite considerable exploration of inquiry and reflection in the literatures of science education and teacher education/teacher professional development over the past century, few theoretical or analytical tools exist to characterize these processes within a naturalistic classroom context. In addition, little is known regarding possible developmental trajectories for inquiry or reflection---for teachers or students---as these processes develop within a classroom context over time. In the dissertation, I use a sociocultural lens to explore these issues with an eye to the ways in which teachers and students develop shared sense-making, rather than from the more traditional perspective of individual teacher activity or student learning. The study includes both theoretical and empirical components. Theoretically, I explore the elaborations of sociocultural theory needed to characterize teacher-student shared sense-making as it develops within a classroom context, and, in particular, the role of inquiry and reflection in that sense-making. I develop a sociocultural model of shared sense-making that attempts to represent the dialectic between the individual and the social, through an elaboration of existing sociocultural and psychological constructs, including Vygotsky's zone of proximal development and theory of mind. Using this model as an interpretive framework, I develop a case study that explores teacher-student shared sense-making within a middle-school science classroom across a year of scaffolded introduction to inquiry-based science instruction. The empirical study serves not only as a test case for the theoretical model, but also informs our understanding regarding possible developmental trajectories and important mechanisms supporting and constraining shared sense-making within inquiry-based science classrooms. Theoretical and empirical findings provide support for the idea that perspectival shifts---that is, shifts of point-of-view that alter relationships and proximities of elements within the interaction space---play an important role in shared sense-making. Findings further suggest that the mutually constitutive interaction of inquiry and reflection plays a key role in flexible shared sense-making. Finally, findings lend support to the idea of a dialectical relationship between human models of shared sense-making and human systems of shared sense-making; that is, the ways in which human minds are coordinated is a work in progress, shaping and shaped by human culture.

Full Text Available ????????????????????????????????????????????????????????147????????????????????????????????????????????????????????????????????????????t???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????The main focus of this paper is to examine any significant differences between participants’ evaluative ratings towards the website in terms of its facilitating effects for learning versus its functionality comprehensiveness. A survey research method was used in the study. 147 high school students who successfully passed to the second phase of the Fifth Annual High Temperature Superconductor Tournament participated in the study. Data analysis yielded that statistically significant differences were found only on areas related to multimedia features. Specifically, the obtained results indicated that students may use their past website surfing experiences as a point of reference and tended to hold a higher expectation toward the embedded multimedia features. As such, their evaluative ratings towards the facilitating effects of multimedia, including the animation, film, and audio, tended to be significantly higher than those of its functionality comprehensiveness. Suggestions for website evaluation and future studies are offered.

Children’s comprehension of informational text: Reading, engaging, and learning  

Directory of Open Access Journals (Sweden)

Full Text Available The Reading, Engaging, and Learning project (REAL investigated whether a classroom intervention that enhanced young children's experience with informational books would increase reading achievement and engagement. Participants attended schools serving low income neighborhoods with 86% African American enrollment. The longitudinal study spanned second through fourth grades. Treatment conditions were: (1 Text Infusion/Reading for Learning Instruction -- students were given greater access to informational books in their classroom libraries and in reading instruction; (2 Text Infusion Alone -- the same books were provided but teachers were not asked to alter their instruction; (3 Traditional Instruction -- students experienced business as usual in the classroom. Children were assessed each year on measures of reading and reading engagement, and classroom instructional practices were observed. On most measures, the informational text infusion intervention did not yield differential growth over time. However, the results inform efforts to increase children’s facility with informational text in the early years in order to improve reading comprehension.

Adapting a successful inquiry-based immersion program to create an Authentic, Hands- on, Field based Curriculum in Environmental Science at Barnard College  

Science.gov (United States)

Adapting a successful inquiry-based immersion program to create an Authentic, Hands-on, Field based Curriculum in Environmental Science at Barnard College T. C. Kenna, S. Pfirman, B. J. Mailloux, M. Stute, R. Kelsey, and P. Bower By adapting a successful inquiry-based immersion program (SEA semester) to the typical college format of classes, we are improving the technical and quantitative skills of undergraduate women and minorities in environmental science and improving their critical thinking and problem-solving by exposing our students to open-ended real-world environmental issues. Our approach uses the Hudson River Estuary as a natural laboratory. In a series of hands-on inquiry-based activities, students use advanced equipment to collect data and samples. Each class session introduces new analytical and data analysis techniques. All classes have the connecting theme of the river. Working with real data is open-ended. Our major findings as indicated by surveys as well as journaling throughout the semester are that the field- based experience significantly contributed to student learning and engagement. Journaling responses indicated that nearly all students discussed the importance and excitement of an authentic research experience. Some students were frustrated with data irregularities, uncertainty in methods and data, and the general challenge of a curriculum with inherent ambiguity. The majority were satisfied with the aims of the course to provide an integrative experience. All students demonstrated transfer of learned skills. This project has had a significant impact on our undergraduate female students: several students have pursued senior thesis projects stemming from grant activities, stating that the field activities were the highlight of their semester. Some students love the experience and want more. Others decide that they want to pursue a different career. All learn how science is conducted and have a better foundation to understand concepts such as sampling, uncertainty, and variability, which are important to many fields. Many of the hands-on curricular activities have been adapted and used with a variety of student, teacher, and faculty groups. Faculty participants in our River Summer program (www.riversummer.org) see earth system science in a way that would be hard to replicate without the hands-on experience. Faculty participants are encouraged to adapt our activities to their own classroom. We are in the process of assembling many of our hands-on field-based activities as fully exportable curricular elements to further increase impacts.

Comprehensive, Mixed-Methods Assessment of a Blended Learning Model for Geospatial Literacy Instruction  

Science.gov (United States)

Geospatial literacy -- the ability to conceptualize, capture, analyze and communicate spatial phenomena -- represents an important competency for 21st Century learners in a period of 'Geospatial Revolution'. Though relevant to in-course learning, these skills are often taught externally, placing time and resource pressures on the service providers - commonly libraries - that are relied upon to provide instruction. The emergence of online and blended modes of instruction has presented a potential means of increasing the cost-effectiveness of such activities, by simultaneously reducing instructional costs, expanding the audience for these resources, and addressing student preferences for asynchronous learning and '24-7' access. During 2011 and 2012, McMaster University Library coordinated the development, implementation and assessment of blended learning modules for geospatial literacy instruction in first-year undergraduate Social Science courses. In this paper, we present the results of a comprehensive mixed-methods approach to assess the efficacy of implementing blended learning modules to replace traditional (face-to-face), library-led, first-year undergraduate geospatial literacy instruction. Focus groups, personal interviews and an online survey were used to assess modules across dimensions of: student use, satisfaction and accessibility requirements (via Universal Instructional Design [UID] principles); instructor and teaching staff perception of pedagogical efficacy and instructional effectiveness; and, administrator cost-benefit assessment of development and implementation. Results showed that both instructors and students identified significant value in using the online modules in a blended-learning setting. Reaffirming assumptions of students' '24/7' learning preferences, over 80% of students reported using the modules on a repeat basis. Students were more likely to use the modules to better understand course content than simply to increase their grade in the course, which demonstrates applicability of the modules beyond a strict surface-learning approach. Instructors felt that giving students access to these modules increased flexibility in how in-class time was used, reduced student anxiety in busy lab sessions, and increased the effectiveness of face-to-face instruction and summative assessments. Though instructors perceived little to no change in grades as a result of the migration to blended-learning instruction, students overwhelmingly perceived a positive impact on their learning, as over 75% felt that the modules improved their geospatial literacy skills and general understanding in the course. Cost-benefit analyses proved challenging, as administrators struggled to estimate the true costs of both traditional instruction and module development. Recommendations for future module modification exposed the competing expectations of generalizing content to increase applicability and cost-effectiveness, versus tailoring modules to specific course content.

Some Key Issues in Creating Inquiry-Based Instructional Practices that Aim at the Understanding of Simple Electric Circuits  

Science.gov (United States)

Many students in secondary schools consider the sciences difficult and unattractive. This applies to physics in particular, a subject in which students attempt to learn and understand numerous theoretical concepts, often without much success. A case in point is the understanding of the concepts current, voltage and resistance in simple electric circuits. In response to these problems, reform initiatives in education strive for a change of the classroom culture, putting emphasis on more authentic contexts and student activities containing elements of inquiry. The challenge then becomes choosing and combining these elements in such a manner that they foster an understanding of theoretical concepts. In this article we reflect on data collected and analyzed from a series of 12 grade 9 physics lessons on simple electric circuits. Drawing from a theoretical framework based on individual (conceptual change based) and socio-cultural views on learning, instruction was designed addressing known conceptual problems and attempting to create a physics (research) culture in the classroom. As the success of the lessons was limited, the focus of the study became to understand which inherent characteristics of inquiry based instruction complicate the process of constructing conceptual understanding. From the analysis of the data collected during the enactment of the lessons three tensions emerged: the tension between open inquiry and student guidance, the tension between students developing their own ideas and getting to know accepted scientific theories, and the tension between fostering scientific interest as part of a scientific research culture and the task oriented school culture. An outlook will be given on the implications for science lessons.

Developing a Student Centered Inquiry Based Teaching Approach at Elementary Level Science in Pakistan-A Three Years Implementation Cycle  

Directory of Open Access Journals (Sweden)

Full Text Available National Curriculum, 2006 is one of the significant measures to improve the quality of education in Pakistan. For General Science, grades IV-VIII, “Student-Centered and Inquiry-Based (SCIB learning” are a key concept of it. However the system for teachers’ in-service training in the country at the Federal and the Provincial levels is pathetic and many of the teachers do not have chances to be equipped for the new ways of teaching science based on the new curriculum. To address this issue and help Pakistan in this significant task of national importance, the Japan International Cooperation Agency (JICA undertaken the challenge of coping with the problem and help Pakistan through a technical cooperation project aiming at establishing a training model that ensures teachers to deliver SCIB science lessons. The purpose of this paper is to describe the SCIB project design and the basic policy of a three years implementation cycle that will support in development and sustainability of science curriculum reforms efforts in Pakistan. The process and achievements of the project outlines the development of teaching plans, master trainers training, teacher training, school cluster and baseline survey of schools and organization of forums at the Federal and the Provincial levels. The paper covers an analysis of some issues related to SCIB teaching model development in the perspectives of ground reality and the lesson learned from implementing such innovative projects in past. The concept of Teaching through Easily Available Material (TEAM and SCIB teaching approach being practiced in Pakistan may be valuable for the developing countries of the region.

The Relationship between Iranian EFL Instructors’ Understanding of Learning Styles and Their Students’ Success in Reading Comprehension  

Directory of Open Access Journals (Sweden)

Full Text Available Many variables reasonably influence teachers’ education. One of these considering variables is being aware of the students’ learning styles. Dörnyei (2005 maintains that individual differences correlate strongly with L2 achievements. Keefe (1979 believes that learning styles might be thought of as cognitive, affective, and physiological traits that are relatively stable indicators of how learners perceive, interact with, and respond to the learning environment. The present study investigated the relationship between Iranian EFL instructors’ understanding of learning styles and their students’ success in reading comprehension tests. To achieve this goal, the researchers randomly selected 240 Iranian EFL instructors at tertiary level with more than three years of experience in teaching reading comprehension courses. The Teacher’s View over Students’ Learning Preferences Inventory (TVSLPI as well as a test of language proficiency (MELAB was employed as the study’s instruments. The findings revealed a significant relationship (p?0.05 between the Iranian EFL instructors’ recognition of learning styles and their students’ success in reading comprehension test. Besides, the results of interviews showed that Iranian instructors have approximately similar attitudes toward teaching reading comprehension in Iranian contexts.

Machine learning for radioxenon event classification for the Comprehensive Nuclear-Test-Ban Treaty.  

Science.gov (United States)

A method of weapon detection for the Comprehensive nuclear-Test-Ban-Treaty (CTBT) consists of monitoring the amount of radioxenon in the atmosphere by measuring and sampling the activity concentration of (131m)Xe, (133)Xe, (133m)Xe, and (135)Xe by radionuclide monitoring. Several explosion samples were simulated based on real data since the measured data of this type is quite rare. These data sets consisted of different circumstances of a nuclear explosion, and are used as training data sets to establish an effective classification model employing state-of-the-art technologies in machine learning. A study was conducted involving classic induction algorithms in machine learning including Naïve Bayes, Neural Networks, Decision Trees, k-Nearest Neighbors, and Support Vector Machines, that revealed that they can successfully be used in this practical application. In particular, our studies show that many induction algorithms in machine learning outperform a simple linear discriminator when a signal is found in a high radioxenon background environment.

"Lunar Phases Project" as a Foundation for the Development of Innovative Inquiry Based ASTRO 101 Activities Utilizing Existing Concept Inventories as Assessment Tools  

Science.gov (United States)

The cause and process of the lunar phases are difficult concepts for undergraduates and non-science majors to grasp. At Florida Gulf Coast University (FGCU) we have combined an inquiry-based instructional method (Mental Model Building) which can be more effective increasing students' conceptual understanding of the lunar phase cycle, together with the students' own observations. Undergraduate and non-science major students completed a hands-on project designed to integrate real observations, application of the scientific method, and Mental Model Building to connect the students' own observations to the Earth-Sun-Moon orientations responsible for their findings. Students' learning was assessed by administering the Lunar Phases Concept Inventory (developed by Rebecca S. Lindell and James P. Olsen, Southern Illinois University) before and after students completed the project, with positive results. We describe the methodology and activities utilized in our Lunar Phases Project, and propose their expansion to a variety of astronomical topics for undergraduate non-science majors and pre-service teachers. We emphasize developing and implementing new instructional strategies through the expansion of the Mental Model Building and similar pedagogical methodologies to develop innovative inquiry-based projects and activities in a variety of astronomical topics for undergraduate non-science majors and pre-service teachers. In order to meaningfully assess the new curriculum tools, we recommend utilizing already existing research-validated concept inventories specific to the astronomy content in the curriculum tools. These inventories can be analyzed to determine the conceptual learning gains achieved by the participating students and with further analysis can be used to refine portions of the activity under study.

Pattern identification or 3D visualization? How best to learn topographic map comprehension  

Science.gov (United States)

Science, Technology, Engineering, and Mathematics (STEM) experts employ many representations that novices find hard to use because they require a critical STEM skill, interpreting two-dimensional (2D) diagrams that represent three-dimensional (3D) information. The current research focuses on learning to interpret topographic maps. Understanding topographic maps requires knowledge of how to interpret the conventions of contour lines, and skill in visualizing that information in 3D (e.g. shape of the terrain). Novices find both tasks difficult. The present study compared two interventions designed to facilitate understanding for topographic maps to minimal text-only instruction. The 3D Visualization group received instruction using 3D gestures and models to help visualize three topographic forms. The Pattern Identification group received instruction using pointing and tracing gestures to help identify the contour patterns associated with the three topographic forms. The Text-based Instruction group received only written instruction explaining topographic maps. All participants then completed a measure of topographic map use. The Pattern Identification group performed better on the map use measure than participants in the Text-based Instruction group, but no significant difference was found between the 3D Visualization group and the other two groups. These results suggest that learning to identify meaningful contour patterns is an effective strategy for learning how to comprehend topographic maps. Future research should address if learning strategies for how to interpret the information represented on a diagram (e.g. identify patterns in the contour lines), before trying to visualize the information in 3D (e.g. visualize the 3D structure of the terrain), also facilitates students' comprehension of other similar types of diagrams.

In addition, the relationship between nonverbal comprehension and social competence was assessed. Thirty LD and 30 NLD boys between 9 and 12 years of age were administered a short form of the Profile of Nonverbal Sensitivity (PONS) to assess nonverbal comprehension; social competence measures included teachers' ratings of aggressive and withdrawn behaviors using the Behavior Problem Checklist, and "blind" judges' ratings of performance on a role-play of friendship-making skills. Under attention-incentive conditions, no performance differences between LD and NLD children were found on the PONS; however, LD children were judged to be more withdrawn and less socially skilled. While PONS scores were not related to other social competence measures, they were associated with academic achievement and IQ. Results emphasize the importance of considering the presence of attentional problems in LD children that may interfere with an accurate assessment of their skills. PMID:6491058

Inquiry-based course in physics and chemistry for preservice K-8 teachers  

Directory of Open Access Journals (Sweden)

Full Text Available We describe an inquiry-based course in physics and chemistry for preservice K-8 teachers developed at California State University Fullerton. The course is one of three developed primarily to enhance the science content understanding of prospective teachers. The course incorporates a number of innovative instructional strategies and is somewhat unusual for its interdisciplinary focus. We describe the course structure in detail, providing examples of course materials and assessment strategies. Finally, we provide research data illustrating both the need for the course and the effectiveness of the course in developing student understanding of selected topics. Student responses to various questions reflect a lack of understanding of many relatively simple physical science concepts, and a level of performance that is usually lower than that in comparable courses serving a general education audience. Additional data suggest that course activities improve student understanding of selected topics, often dramatically.

An Inquiry-Based Microbiology Short Course in the SUMS Program at Hartnell College  

Science.gov (United States)

In this paper, we describe our design and implementation of inquiry-based biology units for the Summer Undergraduate Math and Science (SUMS) program at Hartnell College. The SUMS bridge program is designed to encourage local minority students with unrealized potential to enter and excel in Math and Science college curricula. The inquiry activities we designed prompted students to investigate where bacteria live in the students' environment and how effective different cleaning products are at killing these bacteria. These investigations required students to create their own testable questions and design and carry out experiments to test them. By the end of the program the students demonstrated a command of the scientific method and reported feeling like real scientists. While this unit was taught in four consecutive days, it could easily be translated to a more traditional weekly college lab schedule.

Inquiry-Based Laboratory Course Improves StudentsÂ? Ability to Design Experiments and Interpret Data  

Science.gov (United States)

We redesigned our intermediate-level organismal physiology laboratory course to center on student-designed experiments in plant and human physiology. Our primary goals were to improve the ability of students to design experiments and analyze data. We assessed these abilities at the beginning and end of the semester by giving students an evaluation tool consisting of an experimental scenario, data, and four questions of increasing complexity. The laboratory lecture group improved more than the lecture-only group for the most challenging question. This evidence suggests that our inquiry-based curriculum is achieving its primary goals. The evaluation tool that we developed may be useful to others interested in measuring experimental analysis abilities in their students.

Science teachers' online strategies for seeking inquiry-based lesson activities  

Science.gov (United States)

This paper reports the findings of a mixed methods study that examines how 9th grade science teachers engage in online searches for inquiry-based activities in two different search engines---Google and the Digital Library for Earth System Education. The goal of this dissertation was two-fold: (a) to detail science teacher search behaviors during a realistic online search task related to their teaching, and (b) the effect of search engine affordances on those search practices. At the center of the dissertation activities were an experimental task and talk-aloud protocols of the teachers engaged in the task. The task itself asked teacher participants to search for earth science activities linking the concept of volcanism to plate tectonics. In addition to the experiment and talk-aloud protocol, a demographic survey, content knowledge evaluation, inquiry-based activity evaluation, and post-task structured interview were conducted. Because substantial prior research in non-educational areas has shown that task domain influences search behaviors, it was expected that the science teaching domain would have its own particular influence on teachers' online information seeking. The concept of task domain was developed in terms of an information seeking framework developed by Marchionini (1995). The Marchionini (1995) model of information seeking was used as a guiding framework for the dissertation investigations. The objectives of this dissertation were to characterize the behaviors and products of real-world online information seeking by 9th grade science teachers, and to inform the work of educational software designers.

Relationship between teacher preparedness and inquiry-based instructional practices to students' science achievement: Evidence from TIMSS 2007  

Science.gov (United States)

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

Using a conceptual flow, inquiry based learning, and language development to yield enduring understanding in science  

Science.gov (United States)

This project was designed to incorporate three curriculum development strategies that have been created to increase student achievement in various content areas. Conceptual flow design, the 5E Instructional Model, and English language development strategies were used to create a seventh grade Genetics Unit. The unit was evaluated by three external experts and carried out in two seventh grade classrooms in an effort to assess its effectiveness. Based on the evaluators' feedback, the initial conceptual flow and lessons were found to be inconsistent and confusing. Overall, the organization of this unit seemed to support student achievement. The conceptual flow and the lesson layout of the unit were revised based on the evaluation data. All revisions and the established protocols will serve as models for further science curriculum development in the Norwalk-La Mirada Unified School District.

Seeing the Superiority of Self-monitoring Learning Strategies over Teacher-monitoring Learning in Adult 'Reading Comprehension'  

Directory of Open Access Journals (Sweden)

Full Text Available

This study aims to see the superiority of SMLS on Learners' Receptive skill among the students of Payame-noor and Azad Universities in three different departments and the evaluation that teachers can apply to raise SML among adult learners. It is believed that since the publication of Malcolm Knowles' book in 1975, SML had been applied for adult education for ages. To administer this, SML of reading comprehension was introduced to learners in order to keep an eye on their own learning. To this end, metacognitive strategies rather than cognitive have been more highlighted. To answer, a proficiency test was administered to a total of 382 EFL learners, out of which 200 participants whose scores ranged from 65-80 out of 100 were chosen as the upper-intermediate level as an experimental and control group which were administered the same syllabus and assessment procedures. TOEFL reading test was the instrument of the study. Finally, the data was analyzed through SPSS, using Ttest. Results showed that a significant difference between mean score of TML and SML exist, and the superiority of SML became more highlighted when learners did better after treatment.

Graduate student involvement with designing inquiry-based Earth science field projects for the secondary-level classroom  

Science.gov (United States)

In a secondary-level Earth System Science (ESS) curriculum, the most authentic learning is achieved through the inquiry-based application of real-world research methods in the context of modern understanding of the interconnected components of the Earth System (e.g. lithosphere, hydrosphere, atmosphere, and biosphere). Following the intensive ESST-1 summer institute at UNH, during which teachers enhance their ESS content knowledge via interactions with UNH faculty, staff, and graduate students, each participating teacher is paired with one graduate student fellow for the duration of the school year. This graduate fellow provides a continuing link between the secondary-level school teaching environment and university resources, facilitating the implementation of new content knowledge and current scientific research methodology into the classroom setting. According to the National Science Education Standards (1), scientific inquiry is the central strategy for teaching science. "In successful science classrooms, teachers and students collaborate in the pursuit of ideas... Students formulate questions and devise ways to answer them, they collect data and decide how to represent it, they organize data to generate knowledge, and they test the reliability of the knowledge they have generated. As they proceed, students explain and justify their work to themselves and to one another, learn to cope with problems such as the limitations of equipment, and react to challenges posed by the teacher and by classmates." To speak to these goals, an ongoing local wetland field study has been conceptualized and implemented in three example classrooms (seventh grade general science, ninth grade physical science and tenth grade biology) in two school systems (Oyster River Middle School in Durham, NH and Berlin High School in Berlin, NH). These field studies were conducted using authentic scientific equipment to collect data, including a Li-Cor 840 infrared CO2 analyzer and handmade sediment coring devices. Students utilized GPS and Google Earth technology both to facilitate the generation of research questions and for accurate geographic location during their field studies. An emphasis was placed on maintaining organized records of observations and data using field notebooks. Every site visit was followed by teacher-guided data analyses, and students communicated their results through a variety of formats, including posters, written reports, and oral presentations. These authentic research experiences create an initial data set which may be referenced in future classroom studies, while effectively engaging students in ESS topics that meet national and state educational standards.

Machine learning update for compliance verification of the Comprehensive nuclear-Test-Ban Treaty  

International Nuclear Information System (INIS)

Full text: A possible method of explosion detection for the Comprehensive nuclear- Test-Ban-Treaty (CTBT) consists of monitoring the amount of radioxenon in the atmosphere by measuring and sampling the activity concentration of Xe-131m, Xe-133, Xe-133m, and Xe-135. Several samples were simulated under different circumstances of nuclear detonation, and are used as training datasets to establish an optimal classification model employing state-of-the-art technologies in machine learning (ML). We conducted a preliminary study involving ML algorithms including Naive Bayes, Neural Networks, Decision Trees, k-Nearest Neighbours, and Support Vector Machines. In addition to confirming that ML technology is appropriate for this problem, the study suggested that it can help guide our quest for more accurate simulated data sets, which benefit the entire CTBT community. By using these algorithms, we discovered undesirable artifacts of our initial synthetic explosion data set that needed to be rectified. Our preliminary ML study compelled us to improve the dataset by using a more realistic set of fission yields and by including atmospheric dispersion effects. The fission yields were corrected for amount of time in the explosion cavity and we assume a 10 % release rate each 24 hours. The radioxenon from the explosion site was atmospherically transported (through simulations) to CTBT stations to determine an amount of radioxenon that would be measured by the stations. This was done f measured by the stations. This was done for real atmospheric data. This new synthetic data set and the results of the machine learning algorithm obtained on it will be discussed.

A comprehensive stroke center patient registry: advantages, limitations, and lessons learned  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: The use of medical data registry allows insitutions to effectively manage information for many different investigations related to the registry, as well as evaluate patient's trends over time, with the ultimate goal of recognizing trends that may improve outcomes in a particular patient population.Methods: The purpose of this article is to illustrate our experience with a stroke patient registry at a comprehensive stroke center and highlight advantages, disadvantages, and lessons learned in the process of designing, implementing, and maintaining a stroke registry. We detail the process of stroke registry methodology, common data element (CDE definitions, the generation of manuscripts from a registry, and the limitations.Advantages: The largest advantage of a registry is the ability to prospectively add patients, while allowing investigators to go back and collect information retrospectively if needed. The continuous addition of new patients increases the sample size of studies from year to year, and it also allows reflection on clinical practices from previous years and the ability to investigate trends in patient management over time.Limitations: The greatest limitation in this registry pertains to our single-entry technique where multiple sites of data entry and transfer may generate errors within the registry.Lessons Learned: To reduce the potential for errors and maximize the accuracy and efficiency of the registry, we invest significant time in training competent registry users and project leaders. With effective training and transition of leadership positions, which are continuous and evolving processes, we have attempted to optimize our clinical research registry for knowledge gain and quality improvement at our center.

Lessons Learned from the First Decade of Adaptive Management in Comprehensive Everglades Restoration  

Directory of Open Access Journals (Sweden)

Full Text Available Although few successful examples of large-scale adaptive management applications are available to ecosystem restoration scientists and managers, examining where and how the components of an adaptive management program have been successfully implemented yields insight into what approaches have and have not worked. We document five key lessons learned during the decade-long development and implementation of the Comprehensive Everglades Restoration Plan (CERP Collaborative Adaptive Management Program that might be useful to other adaptive management practitioners. First, legislative and regulatory authorities that require the development of an adaptive management program are necessary to maintain funding and support to set up and implement adaptive management. Second, integration of adaptive management activities into existing institutional processes, and development of technical guidance, helps to ensure that adaptive management activities are understood and roles and responsibilities are clearly articulated so that adaptive management activities are implemented successfully. Third, a strong applied science framework is critical for establishing a prerestoration ecosystem reference condition and understanding of how the system works, as well as for providing a conduit for incorporating new scientific information into the decision-making process. Fourth, clear identification of uncertainties that pose risks to meeting restoration goals helps with the development of hypothesis-driven strategies to inform restoration planning and implementation. Tools such as management options matrices can provide a coherent way to link hypotheses to specific monitoring efforts and options to adjust implementation if performance goals are not achieved. Fifth, independent external peer review of an adaptive management program provides important feedback critical to maintaining and improving adaptive management implementation for ecosystem restoration. These lessons learned have helped shape the CERP Adaptive Management Program and are applicable to other natural resource management and restoration efforts; they can be used to help guide development and implementation of adaptive management programs facing similar challenges.

Grapheme learning and grapheme-color synesthesia: toward a comprehensive model of grapheme-color association.  

Science.gov (United States)

Recent progress in grapheme-color synesthesia research has revealed that certain regularities, as well as individual differences, figure into grapheme-color associations. Although several factors are known to regulate grapheme-color associations, the impact of factors, including their interrelationships, on synesthesia remains unclear. We investigated determinants of synesthetic color for graphemes (characters, letters) of Hiragana, a phonetic script in the Japanese language, and the English alphabet. Results revealed that grapheme ordinality was the strongest predictor of synesthetic colors for Hiragana characters, followed by character sound, and visual shape. Ordinality and visual shapes also significantly predicted synesthetic colors for English alphabet letters, however, sounds did not. The relative impact of grapheme properties on grapheme-color associations and the differences between these two writing systems are accounted for by considering the way graphemes are processed in the brain and introduced during an individual's development. A new model is proposed which takes into account the developmental process of grapheme learning. The model provides comprehensive explanation of synesthetic grapheme-color association determination processes, including the differences across writing systems. PMID:24273504

On the Relationship between Self-regulated Learning Components and L2 Vocabulary Knowledge and Reading Comprehension  

Directory of Open Access Journals (Sweden)

Full Text Available In the past two decades, self-regulation has been the center of heated debate in educational psychology. The present study attempted to investigate the relationship between Iranian EFL learners' self-regulated learning components and vocabulary knowledge and reading comprehension .To fulfill this objective, a 60-item vocabulary and reading comprehension TOEFL test was administered to a sample of 250 male and female college students majoring in English Teaching, English Language Translation, and English Literature. The Persian version of “Self- regulation Trait Questionnaire” was administered to the same participants. Pearson correlation procedure was used to analyze data. Results indicated that the correlation between self-regulated learning components: planning, self -checking, effort and self-efficacy gave mixed results. That is to say, two of the correlation coefficients, self –checking and effort were significant while the other two, planning and self-efficacy, were non-significant.

Employing Inquiry-Based Computer Simulations and Embedded Scientist Videos To Teach Challenging Climate Change and Nature of Science Concepts  

Science.gov (United States)

Design based research was utilized to investigate how students use a greenhouse effect simulation in order to derive best learning practices. During this process, students recognized the authentic scientific process involving computer simulations. The simulation used is embedded within an inquiry-based technology-mediated science curriculum known as Web-based Inquiry Science Environment (WISE). For this research, students from a suburban, diverse, middle school setting use the simulations as part of a two week-long class unit on climate change. A pilot study was conducted during phase one of the research that informed phase two, which encompasses the dissertation. During the pilot study, as students worked through the simulation, evidence of shifts in student motivation, understanding of science content, and ideas about the nature of science became present using a combination of student interviews, focus groups, and students' conversations. Outcomes of the pilot study included improvements to the pedagogical approach. Allowing students to do 'Extreme Testing' (e.g., making the world as hot or cold as possible) and increasing the time for free exploration of the simulation are improvements made as a result of the findings of the pilot study. In the dissertation (phase two of the research design) these findings were implemented in a new curriculum scaled for 85 new students from the same school during the next school year. The modifications included new components implementing simulations as an assessment tool for all students and embedded modeling tools. All students were asked to build pre and post models, however due to technological constraints these were not an effective tool. A non-video group of 44 students was established and another group of 41 video students had a WISE curriculum which included twelve minutes of scientists' conversational videos referencing explicit aspects on the nature of science, specifically the use of models and simulations in science. The students in the video group had marked improvement compared to the non-video group on questions regarding modeling as a tool for representing objects and processes of science modeling aspects as evident by multiple data sources. The findings from the dissertation have potential impacts on improving Nature of Science (NOS) concepts around modeling by efficiently embedding short authentic scientific videos that can be easily used by many educators. Compared to published assessments by the American Association for the Advancement of Science (AAAS), due to the curriculum interventions both groups scored higher than the average United States middle school student on many NOS and climate content constructs.

Introducing inquiry-based hands-on satellite remote sensing technology into the Earth science curricula of Hawaii’s classrooms  

Science.gov (United States)

Currently available satellite technology intended primarily for oceanographic, atmospheric and environmental monitoring efforts and studies can also provide the educational community with valuable pedagogical tools. The “Hawaii from Space” program developed by the NOAA OceanWatch - Central Pacific Office provided two schools within the State of Hawaii with a low-cost Advanced Very High Resolution - Automatic Picture Transmission (AVHRR-APT) satellite receiving station (i.e.: computer, specialized radio receiver, antenna, software, etc), enabling students and teachers alike to operate the equipment for acquiring and downloading “live” visible and InfraRed (IR) imagery from the NOAA AVHRR polar-orbiting satellites directly from within their classrooms. By acquiring, decoding, archiving, and distributing online the daytime and nighttime data they collect over the Hawaiian Archipelago and adjacent regions, students are able to study a wealth of oceanographic, atmospheric and environmental phenomena. The dynamic cooperative learning environment that ensues from the incorporation of hands-on space-based radio communication technology and satellite remote sensing tools within the classroom further serves to empower and engage students. By presenting students with an inquiry-based learning framework, educators can present a multidisciplinary and integrated Earth science curriculum that encompasses various STEM subjects for investigating natural processes from local and regional perspectives. The partnership experiences with Hawaii’s schools highlights the importance of maintaining an active outreach support program for furthering and enhancing the science education of future generations.

A College-Level Inquiry-Based Laboratory Activity on Transiting Planets  

CERN Document Server

We have designed an inquiry-based laboratory activity on transiting extrasolar planets for an introductory college-level astronomy class. The activity was designed with the intent of simultaneously teaching science process skills and factual content about transits and light curves. In the activity, groups of two to four students each formulate a specific science question and design and carry out an investigation using a table-top model of a star and orbiting planet. Each group then presents their findings to other students in their class. In a final presentation, the instructors integrate students' findings with a summary of how measured light curves indicate properties of planetary systems. The activity debuted at Hartnell College in November 2009 and has also been adapted for a lecture-based astronomy course at U.C. Santa Cruz. We present the results of student surveys before and after the astronomy course at Hartnell and discuss how well our activity promotes students' confidence and identity as scientists...

An Inquiry-Based Laboratory Module to Promote Understanding of the Scientific Method and Bacterial Conjugation  

Directory of Open Access Journals (Sweden)

Full Text Available Students are engaged and improve their critical thinking skills in laboratory courses when they have the opportunity to design and conduct inquiry-based experiments that generate novel results. A discovery-driven project for a microbiology, genetics, or multidisciplinary research laboratory course was developed to familiarize students with the scientific method. In this multi-lab module, students determine whether their chosen stress conditions induce conjugation and/or cell death of the model BSL-1 Gram-positive bacterium Bacillus subtilis. Through consultation of the primary literature, students identify conditions or chemicals that can elicit DNA damage, the SOS response, and/or cellular stress.  In groups, students discuss their selected conditions, develop their hypotheses and experimental plans, and formulate their positive and negative controls. Students then subject the B. subtilis donor cells to the stress conditions, mix donors with recipients to allow mating, and plate serial dilutions of the mixtures on selective plates to measure how the treatments affect conjugation frequency and donor cell viability.  Finally, students analyze and discuss their collective data in light of their controls. The goals of this module are to encourage students to be actively involved in the scientific process while contributing to our understanding of the conditions that stimulate horizontal gene transfer in bacteria.

CAREER Educational Outreach: Inquiry-based Atmospheric Science Lessons for K-12 students  

Science.gov (United States)

Climate Comics is a collaborative outreach effort between the Montshire Museum of Science, in Norwich, VT, the Cold Regions Research and Engineering Laboratory (CRREL) research staff, and freelance artist and recent graduate of the Center for Cartoon Studies in White River Junction, VT, Sam Carbaugh. The project involves the cartoonist, the education staff from the museum, and researchers from CRREL creating a series of comic books with polar science and research themes, including sea ice monitoring, sea ice albedo, ice cores, extreme microbial activity, and stories and the process of fieldwork. The aim of the comic series is to provide meaningful science information in a comic-format that is both informative and fun, while highlighting current polar research work done at the lab. The education staff at the Montshire Museum develops and provides a series of hands-on, inquiry-based activity descriptions to complement each comic book, and CRREL researchers provide science background information and reiterative feedback about the comic books as they are being developed. Here, we present the motivation for using the comic-book medium to present polar research topics, the process involved in creating the comics, some unique features of the series, and the finished comic books themselves. Cartoon illustrating ways snow pack can be used to determine past climate information.

The Teaching of Inquiry-based Science in Elementary Classrooms: A Bi-national Comparative Reflection of US and Lithuanian Practices  

Directory of Open Access Journals (Sweden)

Full Text Available This paper offers a comparative reflection on how two nations, the U.S. and Lithuania, are implementing inquiry-based science in elementary classrooms. The qualitative study explored how fourth grade teachers in Southern California and in Lithuania employed effective inquiry-based strategies in their classrooms. A teacher’s use of questioning strategies to guide critical thinking and the role of inquiry-based pedagogy plays in promoting student engagement were commonalities in both countries. “Exercise moments”, resource conservation, and “voyeuristic investigations” were noted in Lithuanian inquiry practices while pacing guides and standards coverage were prevalent issues in US inquiry practices.

Machine learning for compliance verification of the Comprehensive Nuclear-Test-Ban Treaty  

International Nuclear Information System (INIS)

Full text: A possible method of weapon detection for the Comprehensive nuclear-Test-Ban-Treaty consists of monitoring the amount of radioxenon in the atmosphere by measuring and sampling the activity concentration of Xe-131m, Xe-133, Xe-133m, and Xe-135 by radionuclide monitoring. Several samples were obtained under different circumstances of nuclear weapon detonation, and are used as training datasets to establish an optimal classification model employing state-of-the-art technologies in machine learning (ML). We conducted a preliminary study involving ML algorithms including naive Bayes, neural networks, decision trees, k-nearest neighbours, and support vector machines, that revealed that any noise, uncorrelated features, and interactions in extracted weapon signals will cause difficulties for induction algorithms. We developed a novel feature selection approach that addresses these issues. The method is based on the Gram-Schmidt orthogonalization procedure, and can be used to rebuild the whole feature space such that the resulting features are orthonormal to each other (they do not interact with each other, and each resulting feature is sufficiently correlated with the target. This approach was shown to boost performance in 16 out of 36 experiments where no feature selection was applied (in four cases, by more than 10 %), to change nothing in 11 cases and to degrade performance in 9 cases (in only three of these cases, more than 2 % degradation occurred, but never than 2 % degradation occurred, but never more than 4.2 %). This method was also shown to obtain an improvement of 4.59 % in accuracy over 10 state-of-the-art feature selection methods and no feature selection, on our most challenging data set. (author)

Impact of backwards faded scaffolding approach to inquiry-based astronomy laboratory experiences on undergraduate non-science majors' views of scientific inquiry  

Science.gov (United States)

This study explored the impact of a novel inquiry-based astronomy laboratory curriculum designed using the Backwards Faded Scaffolding inquiry teaching framework on non-science majoring undergraduate students' views of the nature of scientific inquiry (NOSI). The study focused on two aspects of NOSI: The Distinction between Data and Evidence (DvE), and The Multiple Methods of Science (MMS). Participants were 220 predominately non-science majoring undergraduate students at a small, doctoral granting, research-extensive university in the Rocky Mountain region of the United States. The student participants were enrolled in an introductory astronomy survey course with an associated laboratory section and were selected in two samples over consecutive fall and spring semesters. The participants also included four of the graduate student instructors who taught the laboratory courses using the intervention curriculum. In the first stage, student participant views of NOSI were measured using the VOSI-4 research instrument before and after the intervention curriculum was administered. The responses were quantified, and the distributions of pre and posttest scores of both samples were separately analyzed to determine if there was a significant improvement in understanding of either of the two aspects of NOSI. The results from both samples were compared to evaluate the consistency of the results. In the second stage, the quantitative results were used to strategically design a qualitative investigation, in which the four lab instructors were interviewed about their observations of how the student participants interacted with the intervention curriculum as compared to traditional lab activities, as well as their suggestions as to how the curriculum may or may not have contributed to the results of the first stage. These interviews were summarized and analyzed for common themes as to how the intervention curriculum influenced the students' understandings of the two aspect of NOSI. According to the results of a Wilcoxon Signed Rank test, there was a significant shift in the distributions of both samples toward a more informed understanding of DvE after the intervention curriculum was administered, while there was no significant change in either direction for understanding of MMS. The results of the instructor interview analysis suggested that the intervention curriculum provided multiple opportunities for students to evaluate and determine the relevance of data in the context of producing evidence-based conclusions directly related to specific research questions, thereby supporting the development of more informed views of DvE. These results also suggested that students might not have realized that they were exclusively engaged in non-experimental type inquiries, as various research methods were not explicitly addressed. The intervention curriculum used a consistently phased stepwise format, which may also have led the students to accommodate their astronomy inquiry experiences within persistent misconceptions of "The Scientific Method" as the only valid means of constructing scientific knowledge, thereby leading to no change in understanding of MMS. The results of the study suggest that a scaffolded, inquiry-based, introductory astronomy laboratory curriculum purposefully designed and scaffolded to enhance students' understandings could be effective in enhancing undergraduate non-science majoring students' views of certain aspects of NOSI. Through scaffolding inquiry experiences that deliver multiple opportunities to engage in authentic scientific inquiries, the novel curriculum provides a valuable resource for the astronomy education community to engage students in learning experiences that reflect the contemporary views of constructivist inquiry-based learning, which focuses on the interpretation of data to create evidence in light of specific questions, as well as opportunities to engage in authentic scientific discourse. As such it can enable astronomy educators in the undergraduate teaching community to support student

Impact of a Backwards Faded Scaffolding (BFS) Approach to Inquiry-Based Astronomy Laboratory Experiences on Undergraduate Non-Science Majors' Views of Scientific Inquiry  

Science.gov (United States)

In an effort to support effective instruction in undergraduate astronomy, the Center for Astronomy and Physics Education Research (CAPER) team introduced an inquiry-based laboratory curriculum designed using Backwards Faded Scaffolding (BFS) inquiry teaching framework. A major goal of the curriculum design was to enhance student learning beyond content knowledge alone toward more informed understandings of scientific inquiry through authentic astronomy inquiry experiences using astronomical data sets available online. This study explored the impact of that curriculum on undergraduate non-science majors’ views of the nature of scientific inquiry (NOSI). Over 200 introductory astronomy students’ were surveyed using the VOSI-4 questionnaire pre and post intervention. These data were analyzed for significant shifts in understanding of two aspects of NOSI; Distinction Between Data and Evidence (DvE) and Multiple Methods of Science (MMS). These results informed an investigation of lab instructors’ observations of students’ interactions with the intervention curriculum compared to traditional labs. Wilcoxon Signed Rank tests showed significant shifts in the distributions of Fall (n=112) and Spring (n=98) samples toward more informed understandings of DvE (Fall, z=-3.811, pinquiry-based, introductory astronomy laboratory curriculum may be effective in enhancing undergraduate non-science majors’ understanding of scientific inquiry and may prove to be a valuable resource for undergraduate astronomy instructors.

Team learning and innovation in nursing teams: Results of a comprehensive research project  

Directory of Open Access Journals (Sweden)

Full Text Available Background/Objective: Noncompliance to implementation of innovations is a problem in nursing teams. In literature, team learning is proposed as a facilitator for change. Still, studies reporting the effects of team learning activities on the implementation of innovations in nursing teams are scarce. To address this gap in literature, this study explored the influence of team learning on the implementation of two innovations. Methods: A literature and three empirical studies were performed to address the research questions of this project. Cross-sectional surveys were conducted between 2008-2011 with a sample of 1111 nurses, representing 79 nursing teams from The Netherlands and Belgium. Results: The results of the literature review revealed research on team learning and innovation in nursing is limited. Team learning included processes to gather, process, and store information from different innovations within the nursing team. The prevalence of team-learning activities was contributed or hindered by individual and contextual factors. Principal component analyses of a 26-item team learning activities scale revealed a five-factor model, explaining 78% of the variance. Team-composition explained 33% of team learning. Analyses on the influence of contextual factors yielded three models that explained 76%, 81% and 83% of the variance in team learning. Positive relationships were detected between team learning activities handling production-oriented information and implementation-effectiveness of an incremental innovation. In addition, team learning activities regarding development-oriented information positively affected the implementation of a radical innovation. Conclusions: Nursing teams undertake different team learning activities to process different types of information that cross over within the nursing team. The way the nursing team is composed had a minor effect on the prevalence of team learning activities in nursing teams. Contextual factors had a major effect on the prevalence of team learning activities. Team learning activities related to the production of nursing care had a positive effect on the implementation of an incremental innovation. Team learning activities related with the development of nursing care of the team positively affected the implementation of a radical innovation. Implications for practice and policy: Throughout team learning nursing teams can enhance their implementation-effectiveness on innovations and increase patient safety and the quality of provided nursing managers and nursing teams can develop effective team learning processes that enable nursing teams to improve implementation-effectiveness of different types of innovations.

Using inquiry-based instruction to meet the standards of No Child Left Behind for middle school earth science  

Science.gov (United States)

This study examined the effectiveness of a specific instructional strategy employed to improve performance on the end-of-the-year Criterion-Referenced Competency Test (CRCT) as mandated by the No Child Left Behind (NCLB) Act of 2001. A growing body of evidence suggests that the perceived pressure to produce adequate aggregated scores on the CRCT causes teachers to neglect other relevant aspects of teaching and attend less to individualized instruction. Rooted in constructivist theory, inquiry-based programs provide a o developmental plan of instruction that affords the opportunity for each student to understand their academic needs and strengths. However, the utility of inquiry-based instruction is largely unknown due to the lack of evaluation studies. To address this problem, this quantitative evaluation measured the impact of the Audet and Jordan inquiry-based instructional model on CRCT test scores of 102 students in a sixth-grade science classroom in one north Georgia school. A series of binomial tests of proportions tested differences between CRCT scores of the program participants and those of a matched control sample selected from other district schools that did not adopt the program. The study found no significant differences on CRCT test scores between the treatment and control groups. The study also found no significant performance differences among genders in the sample using inquiry instruction. This implies that the utility of inquiry education might exist outside the domain of test scores. This study can contribute to social change by informing a reevaluation of the instructional strategies that ideally will serve NCLB high-stakes assessment mandates, while also affording students the individual-level skills needed to become productive members of society.

Teaching Comprehension Skills using Context –Based Texts in Second Language Learning at Tertiary Level  

Directory of Open Access Journals (Sweden)

Full Text Available Content-based reading texts play a vital role in the acquisition of knowledge and information in various fields of studies. Reading these texts at higher institution demands a great deal of effort from the students who are learners of English as a Second Language (ESL. These students who are generally school leavers,  whose level or reading exposure  is confined to Bahasa Malaysia-based text in their primary and secondary education, have to tackle on their own the tremendous demand of reading and comprehending the English content-based texts. These texts are derived from reference books or lecture notes, which are in English and may pose language barriers for the ESL learners. These are also ESL learners when first enter tertiary level; have met a minimum requirement of at least a credit in English as a second language at secondary school level. These reading materials pose comprehension difficulties when they are streamlined into specific field of studies. This paper attempts to look into the training of selected comprehension skills that language lecturers, particularly new ones in the teaching field, can apply the teaching skills to help learners to alleviate the comprehension challenges when reading content-based texts. This paper is also intended to assist new language lecturers who are embarking in ESL teaching of reading comprehension using content-based texts.

Exploring Preservice Elementary Teachers' Understanding of the Essential Features of Inquiry-Based Science Teaching Using Evidence-Based Reflection  

Science.gov (United States)

This study explored preservice elementary teachers' and their mentors' understanding of the essential features of inquiry-based teaching through the use of evidence-based reflection. The web-based video analysis tool (VAT) system was used to support preservice teachers' and mentors' evidence-based reflection during field experiences. Major data sources included VAT reflections and individual interviews. Data analysis indicated that the preservice teachers had been involved in various activities designed to support their understanding of inquiry features in a science methods class; they did not implement all of the features in their actual teaching. Both preservice teachers and mentors had difficulty connecting appropriate inquiry features to each teaching episode, which indicates their lack of understanding of inquiry. Both the preservice teachers and mentors had different levels of understanding for each feature. That is, they tended to understand certain features better than others. They interpreted each feature of inquiry-based science teaching too broadly. They also either had a teacher-centered view or tended to focus on issues unrelated to science teaching.

This study analyzes a professional development (PD) project, entitled Inquiry in Motion, designed to (a) facilitate teacher transformation toward greater quantity and quality of inquiry-based instruction, (b) improve student achievement in science practices and science concepts, and (c) begin to narrow the achievement gap among various groups. This 5-year PD study included 11 schools, 74 middle school teachers, and 9,981 students from diverse, high minority populations. Findings from the quasi-experimental study show statistically significant gains for all student groups (aggregate, males, females, Caucasians, African-Americans, and Hispanics) on all three science Measure of Academic Progress tests (composite, science practices, and science concepts) when compared to students of non-participating teachers. In addition to an increase in overall performance for all groups, a narrowing of the achievement gap of minority students relative to Caucasian students was seen. When combined with other studies, this study affirms that, when facilitated effectively, inquiry-based instruction may benefit all students, for all demographic groups measured.

The Comparison of Language Learning Strategies and Reading Comprehension of Iranian EFL Students Taking Web-based and Face-to-face Instruction  

Directory of Open Access Journals (Sweden)

Full Text Available This study investigated language learning strategies used by EFL web-based learners and face-to-face learners. It also examined the difference between pre-test and post-test reading comprehension scores of EFL students who were exposed to web-based and face-to-face instruction. The participants of the study were 200 Iranian EFL university students. They were randomly assigned into two groups, 100 students in one group taking web-based instruction and 100 students in the other group taking face-to-face instruction. The students took a 50-item translated version of Strategy Inventory for Language Learning and a test of reading comprehension. This scale and the reading comprehension test were given as the pre-test and post-test to all students. During the treatment, summarization-strategy training was used to promote the learning process. The result of an independent samples t-tests revealed that there was no significant difference between the two groups of learners regarding their preferences for language learning strategies. Moreover, the result of a paired samples t-test indicated that there was significant difference between pre-test and post-test reading comprehension scores of EFL students who were exposed to face-to-face instruction. However, there was no significant difference between pre-test and post-test reading comprehension scores of EFL students who were exposed to web-based instruction.

The I-Cleen Project (Inquiring on CLimate & ENergy). Research Meets Education in AN Inquiry-Based Approach to Earth System Science in Italian Classrooms  

Science.gov (United States)

Italian citizens' perception of the seriousness of the issue of climate change is one of the lowest in Europe (Eurobarometer survey, 2008), running next to last among the 28 EU Nations. This has recently driven many national science institutions to take action in order to connect society with the complexities and consequences of climate change. These connection initiatives have encountered a certain deal of opposition in Italian schools. A fact most likely due both to a further weakening of the use of inquiry-based educational practices adopted by teachers and to their reluctance to cooperate on a professional level, which hinders the diffusion of educational practices. I-CLEEN (Inquiring on CLimate and Energy, www.icleen.museum) is a service that offers a new type of link between schools and the complexity of climate change. The project took off in 2008 thanks to the Trento Science Museum (former Tridentine Museum of Natural Science), one of the major Italian science museums that includes both research and science education and dissemination departments. The main aim is to create, using the tools of professional cooperation, a free repository of educational resources that can support teachers in preparing inquiry-based lessons on climate change and earth system science topics, making the task less of a burden. I-CLEEN is inspired by many models, which include: the ARISE (Andrill Research Immersion for Science Educators), the OER (Open Educational Resources) models and those of other projects that have developed similar information gateways such as LRE (Learning Resource Exchange) and DLESE (Digital Library on Earth Science Education). One of the strategies devised by I-CLEEN is to rely upon an editorial team made up of a highly selected group of teachers that interacts with the researchers of the museum and of other Earth system science research centres like the National Institute of Geophysics and Volcanology (INGV). Resource selection, production, revision and publication processes follow a specific procedure that was laid out in a selection policy document according to the guidelines established by the established standards. Thanks to this, all educational resources have a common layout and scientific relevance guaranteed by researcher review that both further facilitate users in taking them up. All the parts that make up the project and their respective activities are fully dealt with using an open source web platform called LifeRay. This platform and the metadata structure made it possible to publish I-CLEEN resources in international project repositories, such as Scientix. The role of the service is thus twofold, gathering local educational practices and linking them to leading international excellences in this field I-CLEEN won the first prize at the 2010 e-learning award and has also been evaluated to determine both the effectiveness of the service among teachers and also the user-friendliness of the Graphic User Interface of the project website. This contribution illustrates several aspects of the I-CLEEN, the results of the two evaluation activities and those coming from the analysis of the project website access data.

Attitudes towards Teaching and Learning Test-taking Strategies for Reading Comprehension Tests: The Case of Iranian EFL Undergraduates  

Directory of Open Access Journals (Sweden)

Full Text Available

Reading, as the most important academic language skill, receives the special focus in second or foreign language teaching. In addition, tests are regularly applied to evaluate academic performance. There are several cognitive and psychological factors which affect test performance. One of such important test-related factors is test-taking strategies, also known as testwiseness. This study was set to probe the attitudes of Iranian EFL undergraduates towards training test-taking strategies. A set of 22 test-taking strategies for multiple-choice reading comprehension tests was taught as extra material to 30 EFL undergraduates in their regular reading classes within 11 sessions. A Likert rating-scale questionnaire was administered at the end of semester. Overall, students revealed positive opinions on teaching and learning of test-taking strategies. Results are discussed and some recommendations are ultimately provided.

Hands-On Science: An Inquiry-Based Integrated Science Content Course for Pre-service Elementary Teachers  

Science.gov (United States)

Much has been discussed about the need for better science curriculum and training for teachers of elementary school classrooms. Future elementary school teachers at UT Austin gain their degree from the College of Education, with significant credits earned in math and science. We will discuss a new inquiry-based curriculum in integrated natural sciences (physics, chemistry, geology, biology, and astronomy) introduced for these teachers. Some items may be of interest to instructors in other college-level science courses: the experience of die-hard lecturer-based instructors transitioning over to an inquiry class, of student mastery of a broad curriculum, and in tailoring a curriculum to a target audience. I will also discuss simultaneous efforts to offer the same curriculum to in-service K-8 teachers and to partner with other universities doing pre-service teacher preparation.

The HSP, the QCN, and the Dragon: Developing inquiry-based QCN instructional modules in Taiwan  

Science.gov (United States)

High Scope Program (HSP) is a long-term project funded by NSC in Taiwan since 2006. It is designed to elevate the quality of science education by means of incorporating emerging science and technology into the traditional curricula in senior high schools. Quake-Catcher Network (QCN), a distributed computing project initiated by Stanford University and UC Riverside, encourages the volunteers to install the low-cost, novel sensors at home and school to build a seismic network. To meet both needs, we have developed a model curriculum that introduces QCN, earthquake science, and cloud computing into high school classrooms. Through professional development workshops, Taiwan cloud-based earthquake science learning platform, and QCN club on Facebook, we have worked closely with Lan-Yang Girl's Senior High School teachers' team to design workable teaching plans through a practical operation of seismic monitoring at home or school. However, some obstacles to learning appear including QCN installation/maintain problems, high self-noise of the sensor, difficulty of introducing earthquake sciences for high school teachers. The challenges of QCN outreach in Taiwan bring out our future plans: (1) development of easy, frequently updated, physics-based QCN-experiments for high school teachers, and (2) design of an interactive learning platform with social networking function for students.

Learning from Mistakes --- A Comprehensive Study on Real World Concurrency Bug Characteristics  

International Nuclear Information System (INIS)

The reality of multi-core hardware has made concurrent programs pervasive. Unfortunately, writing correct concurrent programs is difficult. Addressing this challenge requires advances in multiple directions, including concurrency bug detection, concurrent program testing, concurrent programming model design, etc. Designing effective techniques in all these directions will significantly benefit from a deep understanding of real world concurrency bug characteristics. This paper provides the first (to the best of our knowledge) comprehensive real world concurrency bug characteristic study. Specifically, we have carefully examined concurrency bug patterns, manifestation, and fix strategies of 105 randomly selected real world concurrency bugs from 4 representative server and client opensource applications (MySQL, Apache, Mozilla and OpenOffice). Our study reveals several interesting findings and provides useful guidance for concurrency bug detection, testing, and concurrent programming language design. Some of our findings are as follows: (1) Around one third of the examined non-deadlock concurrency bugs are caused by violation to programmers order intentions, which may not be easily expressed via synchronization primitives like locks and transactional memories; (2) Around 34% of the examined non-deadlock concurrency bugs involve multiple variables, which are not well addressed by existing bug detection tools; (3) About 92% of the examined concurrency bugs can be reliably triggered by enforcing certain orders among no more than 4 memory accesses. This indicates that testing concurrent programs can target at exploring possible orders among every small groups of memory accesses, instead of among all memory accesses; (4) About 73% of the examined non-deadlock concurrency bugs were not fixed by simply adding or changing locks, and many of the fixes were not correct at the first try, indicating the difficulty of reasoning concurrent execution by programmers.

Watershed Watch: Using undergraduate student-driven inquiry-based research projects as a means of engaging undeclared students in the biogeosciences  

Science.gov (United States)

Watershed Watch (NSF 0525433) engages early undergraduate students from two-year and four-year colleges in student-driven full inquiry-based instruction in the biogeosciences. Program goals for Watershed Watch are to test if inquiry-rich student-driven projects sufficiently engage undeclared students (or noncommittal STEM majors) to declare a STEM major (or remain with their STEM major). The program is a partnership between two four-year campuses - the University of New Hampshire (UNH), and Elizabeth City State University (ECSU, in North Carolina); and two two-year campuses - Great Bay Community College (GBCC, in New Hampshire) and the College of the Albemarle (COA, in North Carolina). The program focuses on two watersheds: the Merrimack Ricer Watershed in New Hampshire and Massachusetts, and the Pasquotank River Watershed in Virginia and North Carolina. Both the terrestrial and aquatic components of both watersheds are evaluated using the student-driven projects. A significant component of this program is an intensive two-week Summer Research Institute (SRI), in which undeclared freshmen and sophomores investigate various aspects of their local watershed. Two Summer Research Institutes have been held on the UNH campus (2006 and 2008) and two on the ECSU campus (2007 and 2009). Students develop their own research questions and study design, collect and analyze data, and produce a scientific oral or poster presentation on the last day of the SRI. The course objectives, curriculum and schedule are presented as a model for dissemination for other institutions and programs seeking to develop inquiry-rich programs or courses designed to attract students into biogeoscience disciplines. Data from self-reported student feedback indicate the most important factors explaining high-levels of student motivation and research excellence in the program are: 1) working with committed, energetic, and enthusiastic faculty mentors, and 2) faculty mentors demonstrating high degrees of teamwork and coordination. The past four Summer Research Institutes have engaged over 100 entry-level undergraduate students in the process of learning science by doing it, and approximately 50% of those participating have declared majors in a wide range of science fields. A total of eight Watershed Watch students have presented findings from their SRI research projects at AGU meetings in 2007, 2008, and 2009. This presentation will highlight the lessons learned over the past four years in the Watershed Watch program.

A comparison of graphic organizers on the comprehension and retention of science knowledge among Taiwanese adolescents with learning disabilities  

Science.gov (United States)

The purpose of this study was to examine the effects of mind mapping, as compared to the use of linear outlines, to present science knowledge to adolescents with learning disabilities. Three different types of informationally equivalent instructional materials (i.e., text directly derived from textbooks, mind maps, and outlines) were developed. An alternating treatments design was used to evaluate the relative facilitative effects of mind maps and outlines compared to text on the delivery of science knowledge. Four ninth grade Taiwanese students with learning disabilities were paired and participated in this study. Three dependent measures (free oral retells, production-response tests, and choice-response tests) directly evaluated the participants' comprehension and retention of the content presented, whereas a pretest/posttest was also used to measure generalization. The results showed that the nature of the measures made a difference in the evaluation of the outcomes. On the choice-response tests, three participants outperformed in the mind map condition as compared to the outline and baseline conditions. However, on the production-response tests, only one participant outperformed in the mind map condition as compared to the other two conditions. For oral free retells, none of the participants were able to recall more main ideas from the mind map than from both the outline and the text. Only two participants were able to slightly recall more facts during both the mind map and outline conditions than the baseline condition. The results lend some support to the effectiveness of mind mapping. Analysis of the procedure and results revealed that the facilitative effects of mind mapping may not be fully achieved due to the lack of intensive instruction and study skill training in this study. Limitations of this study included the inconsistency between baseline and intervention conditions, the lack of consistent testing for the mnemonic value of mind mapping, and the small number of participants.

Features include urgent test result notifications; models illustrating expert-approved care processes; concise, expert-approved answers to frequently asked questions (FAQs); a directory of topic-specific experts; and a portfolio for provider licensure and credentialing. The authors evaluate MayoExpert's reach, effectiveness, adoption, implementation, and maintenance. Evaluation data sources included usage statistics, user surveys, and pilot studies.As of October 2013, MayoExpert was available at 94 clinical sites in 12 states and contained 1,368 clinical topics, answers to 7,640 FAQs, and 92 care process models. In 2012, MayoExpert was accessed at least once by 2,578/3,643 (71%) staff physicians, 900/1,374 (66%) midlevel providers, and 1,728/2,291 (75%) residents and fellows. In a 2013 survey of MayoExpert users with 536 respondents, all features were highly rated (?67% favorable). More providers reported using MayoExpert to answer questions before/after than during patient visits (68% versus 36%). During November 2012 to April 2013, MayoExpert sent 1,660 notifications of new-onset atrial fibrillation and 1,590 notifications of prolonged QT. MayoExpert has become part of routine clinical and educational operations, and its care process models now define Mayo Clinic best practices. MayoExpert's infrastructure and content will continue to expand with improved templates and content organization, new care process models, additional notifications, better EMR integration, and improved support for credentialing activities.

We Look More, Listen More, Notice More: Impact of Sustained Professional Development on Head Start Teachers' Inquiry-Based and Culturally-Relevant Science Teaching Practices  

Science.gov (United States)

Despite many scholars' recommendations, science is often avoided during early childhood education. Among the reasons provided by early childhood teachers for the exclusion of science from their daily routines included science anxiety, low self-efficacy with respect to teaching science, lack of experience participating in science activities as students, or the notion that literacy and language are more important during the early years. In minority populations the problem is even greater due to identification of science with the `culture of. This article presents results from Ah Neen Dush, a sustained and transformative professional development program for Head Start teachers on an American Indian Reservation. The goal of the program is to support early childhood teachers in developing inquiry-based and culturally-relevant teaching practices. Through analysis of teachers' classroom practices, surveys and interviews, we explore changes in teachers' attitudes toward science and inquiry-based practices. Classroom observations were conducted using CLASS (Classroom assessment Scoring System), a tool used to evaluate the quality of classroom interactions. After 1 year of professional development teachers' attitudes were found to improve and after 2 years teachers classroom practices were more inquiry-based with statistically significant increases in CLASS observation scores.

Capturing the complexity: Content, type, and amount of instruction and quality of the classroom learning environment synergistically predict third graders' vocabulary and reading comprehension outcomes.  

Science.gov (United States)

We examined classrooms as complex systems that affect students' literacy learning through interacting effects of content and amount of time individual students spent in literacy instruction along with the global quality of the classroom-learning environment. We observed 27 third grade classrooms serving 315 target students using two different observation systems. The first assessed instruction at a more micro-level; specifically, the amount of time individual students spent in literacy instruction defined by the type of instruction, role of the teacher, and content. The second assessed the quality of the classroom-learning environment at a more macro level focusing on classroom organization, teacher responsiveness, and support for vocabulary and language. Results revealed that both global quality of the classroom learning environment and time individual students spent in specific types of literacy instruction covering specific content interacted to predict students' comprehension and vocabulary gains whereas neither system alone did. These findings support a dynamic systems model of how individual children learn in the context of classroom literacy instruction and the classroom-learning environment, which can help to improve observations systems, advance research, elevate teacher evaluation and professional development, and enhance student achievement.

"I am a scientist": How setting conditions that enhance focused concentration positively relate to student motivation and achievement outcomes in inquiry-based science  

Science.gov (United States)

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

A Psychometric Approach to the Development of a 5E Lesson Plan Scoring Instrument for Inquiry-Based Teaching  

Science.gov (United States)

This research centers on the psychometric examination of the structure of an instrument, known as the 5E Lesson Plan (5E ILPv2) rubric for inquiry-based teaching. The instrument is intended to measure an individual's skill in developing written 5E lesson plans for inquiry teaching. In stage one of the instrument's development, an exploratory factor analysis on a fifteen-item 5E ILP instrument revealed only three factor loadings instead of the expected five factors, which led to its subsequent revision. Modifications in the original instrument led to a revised 5E ILPv2 instrument comprised of twenty-one items. This instrument, like its precursor, has a scoring scale that ranges from zero to four points per item. Content validity of the 5E ILPv2 was determined through the expertise of a panel of science educators. Over the course of five semesters, three elementary science methods instructors in three different universities collected post lesson plan data from 224 pre-service teachers enrolled in their courses. Each instructor scored their students' post 5E inquiry lesson plans using the 5E ILPv2 instrument recording a score for each item on the instrument. A factor analysis with maximum likelihood extraction and promax oblique rotation provided evidence of construct validity for five factors and explained 85.5 % of the variability in the total instrument. All items loaded with their theoretical factors exhibiting high ordinal alpha reliability estimates of .94, .99, .96, .97, and .95 for the engage, explore, explain, elaborate, and evaluate subscales respectively. The total instrument reliability estimate was 0.98 indicating strong evidence of total scale reliability.

Teaching the Interior Composition and Rheology of the Earth to Undergraduate Students Using an Inquiry Based Approach  

Science.gov (United States)

Most introductory geology courses include a lesson on the internal layered structure of the Earth. Due to the abstract nature of the content, this topic is difficult to teach using an inquiry-based approach. The challenge is two-fold: first, students cannot directly see the layers from their perspective on the earth's surface, and second, students have trouble grasping the vast scale of the earth, which far exceeds their everyday experiences. In addition, the two separate classification systems for dividing the internal structure of the Earth are often a point of confusion and source of misconceptions. In response to this challenge, we developed an inquiry lesson that scaffolds students' understanding of the compositional and rheological properties of the Earth's interior. The intent is to build students' understanding of the Earth's layers by guiding their attention to the reasons for the separate classification systems and the individual layers. The investigation includes teacher- or material-driven components such as guiding questions and specific hand-samples for analogues as well as student-driven components like collecting data and constructing explanations. The lesson opens with a series of questions designed to elicit students' existing ideas about the Earth's interior. The students are then guided to make observations of hand samples meant to represent examples of the crust and mantle as well as physical materials meant to serve as analogues for the lithosphere and asthenosphere. The lesson concludes with students integrating their observations into a model of the Earth's internal structure that accounts for both the compositional and rheological properties. Although this lesson was originally developed as a roughly 60 minute lesson for a class of 24 students, we also note ways this lesson can be modified for use at a variety of course levels. The lesson was pilot-tested in an introductory Earth Science course for future elementary (K-8) teachers. Data collected includes both pre- and post-instruction drawings as well as responses to multiple-choice test items derived from the Geoscience Content Inventory (GCI).

Closing the science achievement gap for ninth grade English learners through standards- and inquiry-based science instruction  

Science.gov (United States)

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

Does a Creative Learning Medium Matter? Impact of Low Cost Android Tablets on Elementary Students’ English Comprehension, Perceived Performance and Memory Retention  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Android tablet is a relatively newer and cheaper portal electronic device that can be used as a creative learning tool in elementary school setting compared with laptop. However, the effect of Android tablet on students’ learning performance has been rarely studied. Before encouraging schools to implant Android tablet in teaching process, it should be ensured that tablet should at least do no harm on students’ academic performance. This research aims to investigate the impact of an innovative medium—a low cost Android tablet versus paper—on elementary students’ reading comprehension, perceived comprehension performance, and memory retention, and discuss about the implication of the finding and future directions. Method: In Study 1, 18 fourth-graders and 36 sixth-graders read 2 grade-appropriate passages on either a tablet or paper and completed related comprehension tests, then assessed their perceived performance. In Study 2, 16 first-graders attempted to memorize 25 pictures displayed on tablets while another 12 first-graders attempted to memorize 25 pictures displayed on paper. After 1 minute filler activity, participants were shown 50 pictures and asked to identify those they had attempted to memorize. Results: In Study 1, results showed that fourth-graders comprehended better when reading on paper, whereas sixth-graders scored similarly on both media. An interaction effect between “medium” and “gender” was found in the perceived performance of fourth-graders, with boys reporting higher perceived performance when using tablets. In Study 2, first-graders experienced better memory retention when they viewed pictures on paper. Conclusion: The introduction of Android tablets in the classroom did not have a significant negative impact on sixth-graders’ reading comprehension. However, some caution is required when introducing tablets to first-graders and fourth-graders because of the negative effect found in this study. It should also be noted that the use of tablets may enhance the confidence of grade 4 boys during comprehension tasks, but the confidence of grade 4 girls engaged in the same activities may be deteriorated.

THINKING ALOUD, TALKING, AND LEAThinking aloud, talking, and learning to read: esl reading comprehension training in small cooperative groups Thinking aloud, talking, and learning to read: esl reading comprehension training in small cooperative groups  

Directory of Open Access Journals (Sweden)

Full Text Available Training students to become independent skillful readers is a major concern of the EFL reading teacher. How can we best train students in selecting and applying reading strategies so that they become more efficient readers? Can we ensure that an increase in students’ awareness of the need to use strategies will help them become more skillful readers? These questions served as a trigger for this study. The aim of this study was to investigate whether verbal articulation of reading behavior in a small group will improve foreign language comprehension. It is our contention that using verbalization in small groups will raise metacognitive awareness which will in turn enhance effective use of skills and strategies and result in improvement in reading comprehension. We assume that the special features that characterize small group interactions can provide an appropriate setting for raising metacognitive awareness. Training students to become independent skillful readers is a major concern of the EFL reading teacher. How can we best train students in selecting and applying reading strategies so that they become more efficient readers? Can we ensure that an increase in students’ awareness of the need to use strategies will help them become more skillful readers? These questions served as a trigger for this study. The aim of this study was to investigate whether verbal articulation of reading behavior in a small group will improve foreign language comprehension. It is our contention that using verbalization in small groups will raise metacognitive awareness which will in turn enhance effective use of skills and strategies and result in improvement in reading comprehension. We assume that the special features that characterize small group interactions can provide an appropriate setting for raising metacognitive awareness.

A case study of the impact of a reformed science curriculum on student attitudes and learning in a secondary physics classroom  

Science.gov (United States)

This case study examined the impact of the application of an inquiry-based concept related physics curriculum on student attitudes and learning in a secondary physics classroom in southern New Jersey. Students who had previously used a traditional physics curriculum were presented with a 10 week inquiry-based concept related physics curriculum on electricity and magnetism. The study utilized observations, a pre/post attitudinal survey, interviews of students and teachers about their perceptions of the inquiry-based curriculum, and artifact analysis of student work. The results showed a positive change in students' attitude in four of the eight categories designated in the CLASS survey. The observations, interviews and artifact analysis revealed that students were more engaged in learning physics through their discoveries in relating physics concepts to real world applications, a growing personal interest in the value and relevance of science learning and a disconnect between the students' and teacher's perceptions about what is important in learning physics. The study recommends that the rigidity of a traditional physics curriculum with its emphasis on covering many topics and the mathematical language of physics should give way to more inquiry-based concept related curriculum that incorporates exploration, hands-on inquiry activities, and real world connections. The research supports that better efforts be made to familiarize current and future secondary physics educators with the body of research that establishes the benefits of inquiry-based concept related curriculum on physics students.

Curriculum-Dependent and Curriculum-Independent Factors in Preservice Elementary Teachers' Adaptation of Science Curriculum Materials for Inquiry-Based Science  

Science.gov (United States)

In this nested mixed methods study I investigate factors influencing preservice elementary teachers' adaptation of science curriculum materials to better support students' engagement in science as inquiry. Analyses focus on two `reflective teaching assignments' completed by 46 preservice elementary teachers in an undergraduate elementary science methods course in which they were asked to adapt existing science curriculum materials to plan and enact inquiry-based science lessons in elementary classrooms. Data analysis involved regression modeling of artifacts associated with these lessons, as well as in-depth, semester-long case studies of six of these preservice teachers. Results suggest that features of the existing science curriculum materials, including measures of how inquiry-based they were, have a relatively small influence on the preservice teachers' curricular adaptations, while teacher-specific variables account for a much greater percentage of the variance. Evidence from the case studies illustrates the critical impact of the preservice teachers' field placement contexts as an explanatory, teacher-specific factor in their curricular adaptations. These findings have important implications for science teacher educators and science curriculum developers, in terms of not only better understanding how preservice teachers engage with curriculum materials, but also how programmatic features of teacher education programs influence their ability to do so.

Spectrum of physics comprehension  

International Nuclear Information System (INIS)

The paper presents the results of research on the relationship between self-assessed comprehension of physics lectures and final grades of junior high school students (aged 13-15), high school students (aged 16-18) and physics students at the Pedagogical University of Cracow, Poland (aged 21). Students' declared level of comprehension was measured during a physics lecture on a prearranged scale of 1-10 with the use of a personal response system designed for the purpose of this experiment. Through the use of this tool, we obtained about 2000 computer records of students' declared comprehension of a 45 min lecture, which we named ‘the spectrum of comprehension’. In this paper, we present and analyse the correlation between students' declared comprehension of the content presented in the lecture and their final learning results. (paper)

Full Text Available En esta investigación nos aproximamos al procesamiento cognitivo del discurso especializado escrito en tres áreas técnico-profesionales: marítima, industrial y comercial. Nos interesa indagar en la incidencia de algunas variables del texto escrito en la comprensión del discurso especializado por par [...] te de un grupo de 234 sujetos de último año de educación secundaria profesional en la región de Valparaíso, Chile. De manera más específica, exploramos algunas relaciones entre el proceso de comprensión del discurso y un conjunto de textos escritos con contenidos disciplinares especializados, jerarquizados en virtud de ciertas estructuras textuales específicas y de determinadas configuraciones de haces de rasgos lingüísticos co-ocurrentes sistemáticamente y característicos de lo que llamamos Dimensión Foco Informacional (Parodi 2005a). Para ello, se diseñaron y aplicaron seis pruebas de comprensión a la muestra ya indicada. Los resultados indican que existe evidencia empírica significativa para sostener que ciertas estructuras lingüísticas que apunten a una prosa más densamente informacional inciden en el tipo y nivel de comprensión. Al mismo tiempo, se detecta que los rendimientos alcanzados en el manejo de inferencias globales y de aplicación de conocimientos muestran serios problemas en este grupo de alumnos. Abstract in english In this article we approach the cognitive processing of specialized written discourse in three areas of technical-professional education: maritime, industrial, commerce. We search into the influence of some text variables in reading specialized comprehension by a group of 234 students attending last [...] year of secondary professional high schools, in Valparaíso, Chile. More specifically, we explore some relationships between the process of discourse comprehension and a group of written texts with specialized contents, hierarchically organized according to specific text structures and to dimensions of communicative linguistic features co-occurring systematically in the texts, identified upon of what we called Dimension Informational Focus (Parodi 2005a). To accomplish this, we designed and administered six comprehension texts to the group of students previously mentioned. Results show that there is enough empirical evidence to claim that some linguistic structures that identify informationally dense prose affect the kind and level of comprehension. At the same time, for the students under study, very low level achievement in comprehension was detected and global and transfer inferences shows to be the most problematic processes involved in reading, comprehending and learning from these texts.

Comprehensive Nuclear Security Strategies for Nuclear Power Plants in Japan Based on the Lessons Learned from the Fukushima Accident and IAEA Recommendations  

International Nuclear Information System (INIS)

After the Fukushima accident, Japan has improved and strengthened not only safety design but also nuclear security strategies for nuclear power plants (NPPs) to achieve our former prime minister’s statement, “The importance of preparing for unanticipated risks” [1]. In regard to nuclear security for NPPs, the Fukushima accident revealed to us that, in addition to earthquakes and tsunamis, terrorist attacks could also trigger similar severe accidents if adequate nuclear security measures for the NNPs were not prepared. To accomplish our goal, comprehensive nuclear strategies have been carefully developed base on the lessons learned from the Fukushima accident and the following key concepts from IAEA recommendation document: “safety and security harmonization (effective integration)”, “defense in depth”, “risk-based approach”, and “mitigation and minimization of radiological consequence”.

Using high-resolution satellite imagery to engage students in classroom experiences which meld research, the nature of science, and inquiry-based instruction  

Science.gov (United States)

Recognizing the need to bridge the gap between scientific research and the classroom, we have developed an exciting activity which engages students in grades 5-12 using high-resolution satellite imagery to observe Weddell seal populations in Antarctica. Going beyond the scope of the textbook, students experience the challenge researchers face in counting and monitoring animal populations in the field. The activity is presented in a non-expert, non-technical exercise enriched for students, with background information, tutorials, and satellite imagery included. Teachers instruct their class in how to use satellite imagery analysis techniques to collect data on seal populations in the McMurdo Sound region of the Ross Sea, Antarctica. Students participate in this inquiry-based, open-ended exercise to evaluate changes in the seal population within and between seasons. The activity meets the New Generation Science Standards (NGSS) through inquiry-based, real-world application and supports seven Performance Expectations (PE) for grade 5-12. In addition, it offers students a glimpse into the work of a field biologist, promoting interest in entering the STEM career pipeline. As every new Antarctica season unfolds, new imagery will be uploaded to the website allowing each year of students to add their counts to a growing long-term dataset for the classroom. The activity files provide 1) a tutorial in how to use the images to count the populations, 2) background information about Weddell seals in the McMurdo Sound region of the Ross Sea for the students and the teachers, and 3) collections of satellite imagery for spatial and temporal analysis of population fluctuations. Teachers can find all activity files to conduct the activity, including student instructions, on the Polar Geospatial Center's website (http://z.umn.edu/seals).

How to Support Primary Teachers' Implementation of Inquiry: Teachers' Reflections on Teaching Cooperative Inquiry-Based Science  

Science.gov (United States)

Many primary teachers face challenges in teaching inquiry science, often because they believe that they do not have the content knowledge or pedagogical skills to do so. This is a concern given the emphasis attached to teaching science through inquiry where students do not simply learn about science but also do science. This study reports on the reflections of nine grade 6 teachers who taught two cooperative, inquiry science units once a term for two consecutive school terms. The study focused on investigating their perceptions of teaching inquiry science as well as the processes they employed, including the benefits and challenges of this student-centred approach to teaching, with longer task structures that characterises inquiry learning. Although the teachers reflected positively on their experiences teaching the inquiry science units, they also expressed concerns about the challenges that arise when teaching through inquiry. Implications for teacher education are discussed.

The Future Of Nontraditional Occupations For Women: A Comprehensive Review Of The Literature And Implications For Workplace Learning And Performance  

Directory of Open Access Journals (Sweden)

Full Text Available The United States entrance into World War II in 1941 has been credited with beginning a large movement of women into the workforce and the commencement of governmental support for women working in nontraditional occupations. However, the beginning of the support for women in the workforce can be traced back to the 1920 federal mandate to create the Women’s Bureau within the United States Department of Labor. The United States Department of Labor Women’s Bureau is the only federal agency mandated to represent the needs of wage-earning women in the public policy process. The workingwomen tradition has continued into modern day and the number of workingwomen continues to increase steadily, however, the number of women entering nontraditional occupations has declined to 4.9 percent from 7.1 percent in 1983. There has been an effort to increase the number of women in nontraditional occupations in order to increase high skill/high wage employment to provide women with the opportunity for self-sufficiency. Women predominately are employed as clerical workers, childcare providers, sales clerks, and in other low skill/low wage employment, which does not lead to self-sufficiency. Workingwomen largely remain in nonprofessional occupations (73%, where NTO gains have been minimal. This study provided the preliminary exploratory of the literature to establish best practice guidelines to encourage women to enter non-traditional occupations (NTO. The major factor identified from literature is career self-efficacy. Career self-efficacy can be increased through: performance accomplishments, vicarious learning, verbal persuasion, and emotional arousal. The results of this study reveal that women have perceived challenges to nontraditional occupations, which are rather easily overcome but have been a hindrance to their pursuing nontraditional employment. Challenges include sex-role socialization, discrimination and harassment, transportation and childcare issues, the nontraditional workplace may be hazardous which requires special equipment or gear, extreme weather conditions, and the potential job related injuries. This study has indicated and established a positive correlation for the use of best practice guidelines in career counseling and development in regard to career decision-making. Career development and career counseling for NTO’s requires a set of guidelines. The guidelines for NTO’s should include best practice within the industry or field. Best practice guidelines ensure a common, consistent approach to successfully achieve the highest and best possible outcome. Formal training and education for NTO’s have a prescribed set of best practice guidelines. The best practices guidelines for career counseling and career development programs for women entering NTO’s include: (1 focusing on performance accomplishments, (2 participating in observational learning, (3 attending to emotional arousal, and (4 receiving verbal persuasion and encouragement.

Mars Rover Model Celebration: Developing Inquiry Based Lesson Plans to Teach Planetary Science In Elementary And Middle School  

Science.gov (United States)

The recent NASA Mars Rover missions capture the imagination of children, as NASA missions have done for decades. The University of Houston is in the process of developing a prototype of a flexible program that offers children an in-depth educational experience culminating in the design and construction of their own model rover. The existing prototype program is called the Mars Rover Model Celebration. It focuses on students, teachers and parents in grades 3-8. Students will design and build a model of a Mars rover to carry out a student selected science mission on the surface of Mars. The model will be a mock-up, constructed at a minimal cost from art supplies. The students will build the models as part of a project on Mars. The students will be given design criteria for a rover and will do basic research on Mars that will determine the objectives and features of their rover. This project may be used either informally as an after school club or youth group activity or formally as part of a class studying general science, earth science, solar system astronomy or robotics, or as a multi-disciplinary unit for a gifted and talented program. The project's unique strength lies in engaging students in the process of spacecraft design and interesting them in aerospace engineering careers. The project is aimed at elementary and secondary education. Not only will these students learn about scientific fields relevant to the mission (space science, physics, geology, robotics, and more), they will gain an appreciation for how this knowledge is used to tackle complex problems. The low cost of the event makes it an ideal enrichment vehicle for low income schools. It provides activities that provide professional development to educators, curricular support resources using NASA Science Mission Directorate (SMD) content, and provides family opportunities for involvement in K-12 student learning. This paper will describe the development of a detailed set of new 5E lesson plans to support this project as a classroom activity. The challenge of developing interactive learning activities for planetary science will be explored. These lesson plans incorporate state of the art interactive pedagogy and current NASA Planetary Science materials.

Aprendizaje cooperativo en estrategias de comprensión de la lectura: Experiencia en un curso introductorio de Ingeniería / Cooperative learning and reading comprehension strategies: Experience in an introductory engineering course  

Scientific Electronic Library Online (English)

Full Text Available SciELO Venezuela | Language: Spanish Abstract in spanish RESUMEN Se estudió el efecto de un programa cooperativo de aprendizaje de estrategias cognitivas sobre el desempeño en la comprensión de la lectura en una muestra de 52 estudiantes de un curso introductorio de la carrera de ingeniería. El grupo experimental (n = 26) recibió instrucción en un entorno [...] académico de aprendizaje que siempre era de naturaleza cooperativa. El grupo control (n = 26) recibió los mismos contenidos del programa pero en un entorno que no enfatizaba el trabajo sistemáticamente cooperativo entre los estudiantes. El nivel de comprensión lectora se estimó a través de un pre-test y un post-test en una tarea de ejecución individual en lectura y se evaluó el progreso del aprendizaje durante el desarrollo de la experiencia a través de tres tareas cooperativas de ejecución en díadas. Los datos se analizaron a través de la prueba "t" de Student y ANOVA. Los resultados indican que ambos grupos aumentaron su capacidad para comprender textos después de someterse al programa de estrategias, pero el grupo experimental, que trabajó sistemáticamente en forma cooperativa, obtuvo mejores resultados que el grupo de control, encontrándose diferencias estadísticamente significativas entre la ejecución de ambos grupos en cada una de las tareas y en el post-test. Los resultados sugieren la conveniencia de la regulación de los procesos sociales para organizar grupos cooperativos que formen parte de un programa de enseñanza en estrategias cognitivas cuya finalidad sea mejorar la capacidad de comprensión de la lectura en estudiantes que aspiran ingresar a la educación superior Abstract in english ABSTRACT The effect of a cooperative learning program aimed at improving reading comprehension strategies in a sample of 52 students of an engineering introductory course was studied. The experimental group (n = 26) always received instruction in an academic learning environment, cooperative in natu [...] re. The control group (n = 26) received instruction on the same contents but cooperative work was not regularly emphasized. Individual measures of reading comprehension levels before and after the treatment were obtained. Three additional cooperative tasks were assigned to pairs of students in both groups to evaluate progress during training. Data were analyzed by means of a "t" test and ANOVA. Results indicate that at the end of the program students in both groups had improved their capacity to comprehend texts. However, the experimental group -the one that had worked systematically in a cooperative manner- obtained better results than the control group. Differences in performance between groups in each of the three tasks, as well as in the post-test, are statistically significant. Results suggest the need to promote cooperative groups when the purpose is to teach cognitive strategies to improve reading comprehension in pre-university students

Genetically modified food in perspective: an inquiry-based curriculum to help middle school students make sense of tradeoffs  

Science.gov (United States)

To understand how students learn about science controversy, this study examines students' reasoning about tradeoffs in the context of a technology-enhanced curriculum about genetically modified food. The curriculum was designed and refined based on the Scaffolded Knowledge Integration Framework to help students sort and integrate their initial ideas and those presented in the curriculum. Pre-test and post-test scores from 190 students show that students made significant (p genetically modified food controversy. Analyses of students' final papers, in which they took and defended a position on what type of agricultural practice should be used in their geographical region, showed that students were able to provide evidence both for and against their positions, but were less explicit about how they weighed these tradeoffs. These results provide important insights into students' thinking and have implications for curricular design.

The effects of inquiry-based summer enrichment activities on rising eighth graders' knowledge of science processes, attitude toward science, and perceptions of scientists  

Science.gov (United States)

The purpose of this research was to examine the effects of summer science enrichment on eighth-graders' science process skills knowledge, attitude toward science and perceptions of scientists. A single group pre- and post-test design was used to test participants in a summer science enrichment camp, which took place over a three-week period in the summer of 2000. Participants, all of whom were residents of the Mississippi area known as the Delta, lived on the campus of Mississippi Valley State University for the entire course of the camp. Activities included several guided inquiry-based projects such as water rocket design and solar or battery-powered car design. Participants also took trips to an environmental camp in north Mississippi and to the Stennis Space Center on the Mississippi Gulf Coast. Participants worked on their projects in groups, supervised by an undergraduate student "mentor". Participants were encouraged to keep journals of their experiences throughout the camp, and the researcher developed a rubric to evaluate student journals for process knowledge, evidence of planning, reflective thought, and disposition toward science. Tests were used to evaluate student knowledge of process skills, attitude toward science, and perceptions of scientists. On the Test of Integrated Process Skills (Dillashaw & Okey, 1983), the students showed significant improvement overall, but when evaluated separately, males showed significant improvement while females did not. On the Attitude toward Science in School Assessment (Germane, 1988), data indicated that attitude toward science improved significantly for the group as a whole, but upon closer inspection, indicated a significant improvement for the female students only. On Chamber's Draw-a-Scientist Test (1983), analysis of student drawings indicated no significant change in stereotypical images of scientists for the group overall. However, boys' scores indicated a significant improvement when analyzed separately. Journal analysis revealed a need for instruction in their use, but provided an interesting glimpse into students' thoughts. The researcher concluded that summer enrichment camps have potential m terms of helping students improve their science knowledge and their thinking about science. Further research on summer opportunities, inquiry-based instruction, work with mentors, and use of journals is suggested by this work.

Necesidades de aprendizaje de los especialistas de Medicina General Integral sobre los trastornos del espectro autista / Learning needs on Autism Spectrum Disorders of Specialists in General Comprehensive Medicine  

Scientific Electronic Library Online (English)

Full Text Available Introducción: las necesidades de aprendizaje resultan de contrastar un desempeño ideal o propuesto con el real, bien sea para un individuo o un grupo determinado. Constituyen el punto de partida para la búsqueda de una solución pedagógica, capacitante, a fin de contribuir a la transformación cualita [...] tiva de los servicios de salud, y su oportuna identificación una trascendental herramienta de la educación permanente. Objetivo: identificar las necesidades de aprendizaje que sobre los trastornos del espectro autista, tienen los médicos que laboran en los Equipos de Atención Primaria de Salud, del municipio Playa. Método: se aplicó un cuestionario con carácter anónimo, en forma de examen escrito, a 20 especialistas de MGI seleccionados al azar, que laboran en tres policlínicas del extremo Este, del municipio Playa. Resultados: se puntualizaron las deficiencias e insuficiencias de los conocimientos y habilidades profesionales sobre los trastorno del espectro autista, fundamentalmente en lo que respecta a su detección temprana, diagnóstico precoz y escalas de evaluación psicoevolutiva. Conclusiones: a pesar de que los principales problemas de salud de nuestros niños y adolescentes constituyen, en el primer nivel de atención, programas priorizados, sobre todo los que a salud mental infanto-juvenil se refieren, la mayoría de los especialistas exhibió dificultades en el tratamiento integral de estos pacientes, persistiendo el espectro autista como un desorden habitualmente mal explorado y tardíamente diagnosticado, cuya evaluación adolece, en ocasiones, de elementos de obligatoria indagación y conocimiento, lo que afecta el adecuado seguimiento de los menores y su calidad de vida.
