Full Text Available This emerging initiative stemmed from an Office for Learning and Teaching Project (OLT project, Transforming Practice Programme 2016: Student Engagement: Students as Partners in Teaching and Learning. The initiative, trialed in semester two, 2016, involved the selection and training of two experienced students to be leaders of a Closed Facebook ‘students-only’ community which provided advice and triaged queries to appropriate channels. The evaluative processes comprised a participatory action research methodology. Two student leaders who facilitated the Closed Facebook and four academic staff of the project were the participants. The findings demonstrate that the Closed Facebook students-only site provided a safe space, outside the formal learning/classroom environment, where student participants were able to ask and share knowledge. The informal student-for-student learning community complemented the formal structure by facilitating the opportunity for students to become ‘experts’ as university students as they move-through their learning journey.

Full Text Available Unlike the doctoral programs in places where students are paired with advisors at the time of admission itself, most US programs require the students to choose their advisors, and the advisors to formally accept the students as advisees. Little research has been done to understand how students and faculty approach this mutual selection and pairing process. This paper examines this process in STEM departments (Science, Technology, Engineering and Mathematics, with specific focus on factors influencing the decisions. Based on focus groups and interviews of doctoral students and faculty from STEM departments in an American university, we identify criteria applied by students and faculty in making their choices. Students were found to assess faculty on available funding, area of research, personality, ability to graduate students fast, and career prospects for students, and faculty to assess students on their qualifications/credentials and perceived ability to contribute to research. We also found that this mutual assessment was not objective, but influenced by perceptions associated with faculty gender and career stage, and student nationality. In the end, whether students and faculty were actually paired with persons of their choice depended on departmental factors including prevalent pairing practices, restrictions on student numbers per faculty, and reward structure. We discuss implications of the findings for research and practice.

Alcohol abuse continues to be an issue of major concern for the health and well-being of college students. Estimates are that over 80% of college students are involved in the campus "alcohol culture." Annually, close to 2000 students die in the United States due to alcohol-related accidents, with another 600,000 sustaining injury due to alcohol-related incidents (NIAAA, 2013). Students enrolled in a Psychopharmacology course engaged in action projects (community outreach) focused on alcohol abuse on our campus. Research has indicated that these types of projects can increase student engagement in course material and foster important skills, including working with peers and developing involvement in one's community. This paper describes the structure and requirements of five student outreach projects and the final projects designed by the students, summarizes the grading and assessment of the projects, and discusses the rewards and challenges of incorporating such projects into a course.

A cranked mean-field model that takes into account both T=1 and T=0 pairing interactions is presented. The like-particle pairing interaction is described by means of a standard seniority force. The neutron-proton channel includes simultaneously correlations among particles moving in time reversed orbits (T=1) and identical orbits (T=0). The coupling between different pairing channels and nuclear rotation is taken into account selfconsistently. Approximate number-projection is included by means of the Lipkin-Nogami method. The transitions between different pairing phases are discussed as a function of neutron/proton excess, T{sub z}, and rotational frequency, {Dirac_h}{omega}.

This paper describes a series of student projects which are intended to complement theoretical education in acoustics and engineering noise control with practical experience. The projects are also intended to enhance the students' ability to work in a team, to manage a project, and to present their results. The projects are carried out in close cooperation with industrial partners so that the students can get a taste of the professional life of noise control engineers. The organization of such a project, its execution, and some of the results from the most recent student project are presented as a demonstrative example. This latest project involved the creation of noise maps of a production hall, the acoustic analysis of a packaging machine, and the acoustic analysis of a spiral vibratory conveyor. Upon completion of the analysis, students then designed, applied, and verified some simple preliminary noise reduction measures to demonstrate the potential of these techniques. © 2012 Acoustical Society of America

Full Text Available Abstract Background As life expectancy increases, dementia incidence will also increase, creating a greater need for physicians well-trained to provide integrated geriatric care. However, research suggests medical students have limited knowledge or interest in pursuing geriatric or dementia care. The purpose of this study is to evaluate the PAIRS Program and its effectiveness in enhancing medical education as a service-learning activity and replication model for the Buddy ProgramTM. Methods Between 2007 and 2011, four consecutive classes of first year Boston University School of Medicine students (n = 45; 24 ± 3 years, 58% female, 53% White participated in a year-long program in which they were paired with a patient with early-stage Alzheimer’s disease (AD. Assessments included pre- and post-program dementia knowledge tests and a post-program reflective essay. Results Program completion was 100% (n = 45. A paired-sample t-test revealed a modest improvement in dementia knowledge post-program (p  Conclusions Quantitative and qualitative findings suggest that the PAIRS Program can enhance the acquisition of knowledge, skills, and positive attitudes regarding geriatric healthcare in future generations of physicians, a skill set that is becoming increasingly relevant in light of the rapidly aging population. Furthermore, results suggest that The Buddy ProgramTM model can be successfully replicated.

The two-proton separation energy is studied by performing a particle-number projection with and without inclusion of the isovector neutron-proton (np) pairing correlations. It is numerically evaluated for even-even rare-earth nuclei such that the np pairing parameter is non-zero. It is shown that the two-proton separation energy values calculated using the two approaches join, for almost all the considered elements, for the highest values of (N-Z). However, the results including the np pairing correlations are closest to the experimental data when available. Moreover, the two methods lead to the same prediction of the two-proton drip-line position, except for the Dysprosium and the Tungsten.

Influence of isovector pairing and particle-number projection effects on spectroscopic factors for one-pair like-particle transfer reactions in proton-rich even-even nuclei

Benbouzid, Y.; Allal, N. H.; Fellah, M.; Oudih, M. R.

2018-04-01

Isovector neutron-proton (np) pairing and particle-number fluctuation effects on the spectroscopic factors (SF) corresponding to one-pair like-particle transfer reactions in proton-rich even-even nuclei are studied. With this aim, expressions of the SF corresponding to two-neutron stripping and two-proton pick-up reactions, which take into account the isovector np pairing effect, are established within the generalized BCS approach, using a schematic definition proposed by Chasman. Expressions of the same SF which strictly conserve the particle number are also established within the Sharp-BCS (SBCS) discrete projection method. In both cases, it is shown that these expressions generalize those obtained when only the pairing between like particles is considered. First, the formalism is tested within the Richardson schematic model. Second, it is applied to study even-even proton-rich nuclei using the single-particle energies of a Woods-Saxon mean-field. In both cases, it is shown that the np pairing effect and the particle-number projection effect on the SF values are important, particularly in N = Z nuclei, and must then be taken into account.

Pairing as an instructional strategy to promote soft skills amongst clinical dental students.

Training dentists today is challenging as they are expected to provide a wide range of dental care. In the provision of good dental care, soft skills are equally important as clinical skills. Therefore in dental education the development of soft skills are of prime concern. This study sought to identify the development of soft skills when dental students are paired in their clinical training. In this perception study, four open-ended items were used to elicit students' feedback on the appropriateness of using clinical pairing as an instructional strategy to promote soft skills. The most frequently cited soft skills were teamwork (70%) and communication (25%) skills. However, both negative and positive behaviours were reported. As for critical thinking and problem solving skills, more positive behaviours were reported for abilities such as to explain, analyze, find ideas and alternative solutions, and make decisions. Leadership among peers was not evident as leading without legitimate authority could be a hindrance to its development. If clinical pairing is to be used as an effective instructional strategy to promote soft skills amongst students, clear guidelines need to be developed to prepare students to work in a dental team and the use of appropriate assessment tools can facilitate the development of these soft skills. © 2013 John Wiley & Sons A/S.

Kac's question, planar isospectral pairs and involutions in projective space

International Nuclear Information System (INIS)

Thas, Koen

2006-01-01

In a paper published in Am. Math. Mon. (1966 73 1-23), Kac asked his famous question 'Can one hear the shape of a drum?'. Gordon et al answered this question negatively by constructing planar isospectral pairs in their paper published in Invent. Math. (1992 110 1-22). Only a finite number of pairs have been constructed till now. Further in J. Phys. A: Math. Gen. (2005 38 L477-83), Giraud showed that most of the known examples can be generated from solutions of a certain equation which involves certain involutions of an n-dimensional projective space over some finite field. He then generated all possible solutions when n = 2. In this letter we handle all dimensions, and show that no other examples arise. (letter to the editor)

Full Text Available Anxiety and inadequate motivation due to misapplication of some language teaching methodologies and learning materials have been shown to affect the Willingness to Communicate of students in EFL programs. This study used a Project-Based Language Learning to improve learning motivation and content relevance. Students were grouped into pairs to conduct fieldwork activities on their chosen topics and learned the English language that was suitable for describing their activities and outcomes. They interacted with content and peers through Web 2.0 environments. In the classroom, they engaged in communicative tasks in a jigsaw format and presented their projects where their peers used an online rubric and forum to give feedback. They also participated in a speech contest with peers outside their class or from another university in order to broaden their confidence. Findings from this study show that students were able to develop the language and evaluation skills for presentation. Additionally, they indicated a reduction in communication anxiety.

We show that two different tensors defining the same translational invariant injective projected entangled pair state (PEPS) in a square lattice must be the same up to a trivial gauge freedom. This allows us to characterize the existence of any local or spatial symmetry in the state. As an application of these results we prove that a SU(2) invariant PEPS with half-integer spin cannot be injective, which can be seen as a Lieb-Shultz-Mattis theorem in this context. We also give the natural generalization for U(1) symmetry in the spirit of Oshikawa-Yamanaka-Affleck, and show that a PEPS with Wilson loops cannot be injective.

We present the serendipitous discovery of a projected pair of quasi-stellar objects (QSOs) with an angular separation of Δ θ = 4.50 arcsec. The redshifts of the two QSOs are widely different: one, our program target, is a QSO with a spectrum consistent with being a narrow line Seyfert 1 active galactic nucleus at z = 2.05. For this target we detect Ly α , C iv, and C iii]. The other QSO, which by chance was included on the spectroscopic slit, is a Type 1 QSO at a redshift of z = 1.68, for which we detect C iv, C iii], and Mg ii. We compare this system to previously detected projected QSO pairs and find that only about a dozen previously known pairs have smaller angular separation.

Full Text Available Project Citizen is a civic education curriculum used across the United States and internationally, yet research about its impact on students is lacking in the literature. This article reports the results of a preliminary study designed to answer the following questions: What are students’ attitudes toward and perceptions of Project Citizen? How do their attitudes and perceptions compare to those of students who completed senior projects? Tenhigh school students and 23 first-year college students completed a questionnaire designed for this study. Our findings indicate that the high school students had positive perceptions of Project Citizen, and they self-reported anunderstanding and high levels of efficacy regarding civic responsibility. In contrast, the first-year college students had lower levels of efficacy regarding civic responsibility. Our findings suggest the importance of specific learning experiences to help students develop civic knowledge, skills, and dispositions, and indicate the need for further research into civic programs such as Project Citizen

Full Text Available Senior undergraduate research projects are important components of most undergraduate science degrees. The delivery of such projects in a distance education format is challenging. Athabasca University (AU science project courses allow distance education students to complete research project courses by working with research supervisors in their local area, coordinated at a distance by AU faculty. This paper presents demographics and course performance for 155 students over five years. Pass rates were similar to other distance education courses. Research students were surveyed by questionnaire, and external supervisors and AU faculty were interviewed, to examine the outcomes of these project courses for each group. Students reported high levels of satisfaction with the course, local supervisors, and faculty coordinators. Students also reported that the experience increased their interest in research, and the probability that they would pursue graduate or additional certification. Local supervisors and faculty affirmed that the purposes of project courses are to introduce the student to research, provide opportunity for students to use their cumulative knowledge, develop cognitive abilities, and independent thinking. The advantages and challenges associated with this course model are discussed.

The Undergraduate Student Instrument Project (USIP) - building the STEM workforce by providing exciting, multi-disciplinary, student-led suborbital flight projects.

Dingwall, B. J.

2015-12-01

NASA's Science Mission Directorate (SMD) recognizes that suborbital carriers play a vital role in training our country's future science and technology leaders. SMD created the Undergraduate Student Instrument Project (USIP) to offer students the opportunity to design, build, and fly instruments on NASA's unique suborbital research platforms. This paper explores the projects, the impact, and the lessons learned of USIP. USIP required undergraduate teams to design, build, and fly a scientific instrument in 18 months or less. Students were required to form collaborative multidisciplinary teams to design, develop and build their instrument. Teams quickly learned that success required skills often overlooked in an academic environment. Teams quickly learned to share technical information in a clear and concise manner that could be understood by other disciplines. The aggressive schedule required team members to hold each other accountable for progress while maintaining team unity. Unanticipated problems and technical issues led students to a deeper understanding of the need for schedule and cost reserves. Students exited the program with a far deeper understanding of project management and team dynamics. Through the process of designing and building an instrument that will enable new research transforms students from textbook learners to developers of new knowledge. The initial USIP project funded 10 undergraduate teams that flew a broad range of scientific instruments on scientific balloons, sounding rockets, commercial rockets and aircraft. Students were required to prepare for and conduct the major reviews that are an integral part of systems development. Each project conducted a Preliminary Design Review, Critical Design Review and Mission Readiness review for NASA officials and flight platform providers. By preparing and presenting their designs to technical experts, the students developed a deeper understanding of the technical and programmatic project pieces that

This article builds on an earlier viewpoint regarding the need for project-focussed fieldwork. It presents the findings of an evaluative study into the value of project placements undertaken by final year graduate entry master's students as part of a capstone subject. The authors argue that provision of project placements enable impending graduates to develop and implement macro level strategies to develop prevention, resource and service development skills often required of contemporary occupational therapy practitioners. A qualitative approach is adopted. Student cohorts from 2005 and 2006 completed open-ended, written questionnaires, and agency project sponsors were interviewed to obtain their perspectives of the project placement experience. Despite some concern that project placements might be undertaken at the expense of 'clinical' placements these findings reveal that projects managed by students were perceived by services to add great value enabling them to advance important priorities. Students and sponsors highlighted a range of positive learning outcomes, including the ability to work collaboratively with supervisors and develop advanced communication skills and political acumen. The success of such placements depends on supportive supervision from academic staff. CONCLUSIONS AND SIGNIFICANCE OF THE STUDY: The findings promote project placements as a highly authentic aspect of work integrated learning enabling learners to draw together a range of attributes that support the ability to manage complex issues that have occupational relevance at a macro level. In addition, such experiences help learners to develop agency and political acumen both increasingly important capabilities for the contemporary workplace. © 2012 The Authors Australian Occupational Therapy Journal © 2012 Occupational Therapy Australia.

The Vermont EPSCoR Streams Project engages a diverse group of undergraduates, high school students, and their teachers in hands-on water quality research and exposes them to the process of science. The project aims to (1) recruit students to science careers and (2) create a water quality database comprised of high-quality data collected by undergraduates and high school groups. The project is the training and outreach mechanism of the Complex Systems Modeling for Environmental Problem Solving research program, an NSF-funded program at the University of Vermont (UVM) that provides computational strategies and fresh approaches for understanding how natural and built environments interact. The Streams Project trains participants to collect and analyze data from streams throughout Vermont and at limited sites in Connecticut, New York, and Puerto Rico. Participants contribute their data to an online database and use it to complete individual research projects that focus on the effect of land use and precipitation patterns on selected measures of stream water quality. All undergraduates and some high school groups are paired with a mentor, who is either a graduate student or a faculty member at UVM or other college. Each year, undergraduate students and high school groups are trained to (1) collect water and macroinvertebrate samples from streams, (2) analyze water samples for total phosphorus, bacteria, and total suspended solids in an analytical laboratory, and/or (3) use geographic information systems (GIS) to assess landscape-level data for their watersheds. After training, high school groups collect samples from stream sites on a twice-monthly basis while undergraduates conduct semi-autonomous field and laboratory research. High school groups monitor sites in two watersheds with contrasting land uses. Undergraduate projects are shaped by the interests of students and their mentors. Contribution to a common database provides students with the option to expand the

Purpose: A robust and accurate method that allows the automatic detection of fiducial markers in MV and kV projection image pairs is proposed. The method allows to automatically correct for inter or intrafraction motion. Methods: Intratreatment MV projection images are acquired during each of five treatment beams of prostate cancer patients with four implanted fiducial markers. The projection images are first preprocessed using a series of marker enhancing filters. 2D candidate marker locations are generated for each of the filtered projection images and 3D candidate marker locations are reconstructed by pairing candidates in subsequent projection images. The correct marker positions are retrieved in 3D by the minimization of a cost function that combines 2D image intensity and 3D geometric or shape information for the entire marker configuration simultaneously. This optimization problem is solved using dynamic programming such that the globally optimal configuration for all markers is always found. Translational interfraction and intrafraction prostate motion and the required patient repositioning is assessed from the position of the centroid of the detected markers in different MV image pairs. The method was validated on a phantom using CT as ground-truth and on clinical data sets of 16 patients using manual marker annotations as ground-truth. Results: The entire setup was confirmed to be accurate to around 1 mm by the phantom measurements. The reproducibility of the manual marker selection was less than 3.5 pixels in the MV images. In patient images, markers were correctly identified in at least 99% of the cases for anterior projection images and 96% of the cases for oblique projection images. The average marker detection accuracy was 1.4±1.8 pixels in the projection images. The centroid of all four reconstructed marker positions in 3D was positioned within 2 mm of the ground-truth position in 99.73% of all cases. Detecting four markers in a pair of MV images

Buhmann, Caecilie Böck

2007-01-01

The Nuclear Weapons Inheritance Project is a student run and student initiated project founded in 2001 with the purpose of increasing awareness of health effects of nuclear policies and empowering university students to take action in a local and international context. The project uses dialogues to discuss nuclear disarmament with university students and a method of interactive peer education to train new trainers. The project has met more than 1500 students in nuclear weapon states in dialogue and trained about 400 students from all over the world. This article describes the methods and results of the project and discuss how the experience of the project can be used in other projects seeking to increase awareness of a topic and to initiate action on social injustice.

DiBartolomeis, Susan M.

2011-01-01

Several reports on science education suggest that students at all levels learn better if they are immersed in a project that is long term, yielding results that require analysis and interpretation. I describe a 12-wk laboratory project suitable for upper-level undergraduates and first-year graduate students, in which the students molecularly locate and map a gene from Drosophila melanogaster called dusky and one of dusky's mutant alleles. The mapping strategy uses restriction fragment length polymorphism analysis; hence, students perform most of the basic techniques of molecular biology (DNA isolation, restriction enzyme digestion and mapping, plasmid vector subcloning, agarose and polyacrylamide gel electrophoresis, DNA labeling, and Southern hybridization) toward the single goal of characterizing dusky and the mutant allele dusky73. Students work as individuals, pairs, or in groups of up to four students. Some exercises require multitasking and collaboration between groups. Finally, results from everyone in the class are required for the final analysis. Results of pre- and postquizzes and surveys indicate that student knowledge of appropriate topics and skills increased significantly, students felt more confident in the laboratory, and students found the laboratory project interesting and challenging. Former students report that the lab was useful in their careers. PMID:21364104

Twisted injectivity in projected entangled pair states and the classification of quantum phases

Energy Technology Data Exchange (ETDEWEB)

Buerschaper, Oliver, E-mail: obuerschaper@perimeterinstitute.ca

2014-12-15

We introduce a class of projected entangled pair states (PEPS) which is based on a group symmetry twisted by a 3-cocycle of the group. This twisted symmetry is expressed as a matrix product operator (MPO) with bond dimension greater than 1 and acts on the virtual boundary of a PEPS tensor. We show that it gives rise to a new standard form for PEPS from which we construct a family of local Hamiltonians which are gapped, frustration-free and include fixed points of the renormalization group flow. Based on this insight, we advance the classification of 2D gapped quantum spin systems by showing how this new standard form for PEPS determines the emergent topological order of these local Hamiltonians. Specifically, we identify their universality class as DIJKGRAAF–WITTEN topological quantum field theory (TQFT). - Highlights: • We introduce a new standard form for projected entangled pair states via a twisted group symmetry which is given by nontrivial matrix product operators. • We construct a large family of gapped, frustration-free Hamiltonians in two dimensions from this new standard form. • We rigorously show how this new standard form for low energy states determines the emergent topological order.

Present study was carried out to determine the inhibiting factors influencing the student's research projects from the view point of Yasuj University of Medical Sciences students in 2008. Materials & Methods: In this cross sectional study 96 students of Yasuj Medical University were selected by stratified random sampling. The data were collected by validate & reliable questionnaire, containing demographic information, inhibiting factors related to students (personal and organization. The data were analyzed by SPSS software. Results: The mean scores against the personal barriers and the organizational barriers questions were 43.23±12.96 and 62.58±12.08 respectively. There was a significant difference between personal and organizational barriers (P<0.001 and personal barriers were more important. According to the results, the student's inadequate skills & knowledge of research methodology and lack of awareness of research topics were the most prevalent personal barriers. The most prevalent organizational barriers were unavailability of research consulters, inadequate research skills of consulter, insufficient facilities & equipment and lack of motivating staff & faculties. Other variables such as gender, subject of study and research experience are mentioned in the full text. Conclusion: This study showed that the personal barriers were more important than organizational barriers which interfere with the student's research projects. This can be corrected and controlled by teachers, faculty members, university officials and students, themselves.

Improving Technological Competency in Nursing Students: The Passport Project

Directory of Open Access Journals (Sweden)

Julie Edwards

2011-07-01

Full Text Available Integration of informatics competency into a nursing curriculum is important to ensure success throughout the education and career of contemporary nursing students. As enrollment in nursing programs increases, the diverse population of students from many different cultural and socioeconomic backgrounds presents a challenge for faculty in addressing unique learning needs. Competency in informatics will allow the beginning nursing student to navigate the on-line teaching software used by colleges. With rigorous expectations in nursing programs, students may feel overwhelmed with assignments, organization, and time management. Frustration may build when students struggle with basic informatics competency, often leaving them unable to navigate instructional websites or work with necessary on-line learning content. The purpose of this project, Passport Project for Nursing Success, was to assess the skills, knowledge, and informatics comfort level of students, while providing computer training and teaching for beginning nursing students in an undergraduate nursing program in Central Illinois. The community college encompassed students from a ten county area, with 20 percent of the student population enrolled in the Applied Science curriculum. Initial implementation occurred prior to the students' first nursing course and emphasized basic skills necessary to navigate on-line learning software, library search engines, and electronic communication. The greatest barrier to successful implementation was faculty resistance and academic support during completion of the initial implementation of the Passport Project. Post- project surveys indicated overwhelming student support for the education received and improved retention rates of first semester nursing students.

Number projected statistics and the pairing correlations at high excitation energies

1993-01-01

We analyze the use of particle-number projected statistics (PNPS) as an effective way to include the quantum and statistical fluctuations, associated with the pairing degree of freedom, left out in finite-temperature mean-field theories. As a numerical application the exact-soluble degenerate model is worked out. In particular, we find that the sharp temperature-induced superfluid-normal phase transition, predicted in the mean-field approximations, is washed out in the PNPS. Some approximations as well as the Landau prescription to include statistical fluctuations are also discussed. We find that the Landau prescription provides a reasonable approximation to the PNPS.

2013-04-01

Full Text Available In the second semester of the second year of a Mechanical Engineering course, students are supposed to take a Module Outside the Main Discipline (MOMD. This module is chosen to be “Product Design Exercise” a module that is offered to Chemical Engineering students at the same stage. The aim was to expose students from both disciplines to an environment in which they are encouraged to interact with and engage team members with a relatively different background. The students were divided into eight groups all comprised of Chemical and Mechanical Engineering students, and they were offered different open-ended projects that were selected to exploit the knowledge developed by the students thus far and they were slightly skewed towards Chemical Engineering. The students demonstrated a high level of cooperation and motivation throughout the period of the project. Effective communication and closing of knowledge gaps were prevalent. At the end of the project period, students produced a journal paper in lieu of the project report.

Latulippe, Christine; Latulippe, Joe

2014-01-01

This qualitative study surveyed 102 differential-equations students in order to investigate how students participating in writing projects in university-level mathematics courses perceive the benefits of writing in the mathematics classroom. Based on previous literature on writing in mathematics, students were asked specifically about the benefits of writing projects as a means to explore practical uses of mathematics, deepen content knowledge, and strengthen communication. Student responses indicated an awareness of these benefits, supporting justifications commonly cited by instructors assigning writing projects. Open-ended survey responses highlighted additional themes which students associated with writing in mathematics, including using software programs and technology, working in groups, and stimulating interest in mathematics. This study provides student feedback to support the use of writing projects in mathematics, as well as student input, which can be utilized to strengthen the impact of writing projects in mathematics.

Student-Designed Service-Learning Projects in an Undergraduate Neurobiology Course

Directory of Open Access Journals (Sweden)

Katharine V. Northcutt

2015-12-01

Full Text Available One of the challenges in teaching a service-learning course is obtaining student buy-in from all students in the course. To circumvent this problem, I have let students in my undergraduate Neurobiology course design their own service-learning projects at the beginning of the semester. Although this can be chaotic because it requires last-minute planning, I have made it successful through facilitating student communication in the classroom, requiring thorough project proposals, meeting with students regularly, and monitoring group progress through written reflection papers. Most of my students have strong opinions about the types of projects that they want to carry out, and many students have used connections that they have already made with local organizations. Almost all projects that students have designed to this point involve teaching basic concepts of neurobiology to children of various ages while simultaneously sparking their interest in science. Through taking ownership of the project and designing it such that it works well with their strengths, interests, and weekly schedule, students have become more engaged in service learning and view it as a valuable experience. Despite some class time being shifted away from more traditional assignments, students have performed equally well in the course, and they are more eager to talk with others about course concepts. Furthermore, the feedback that I have received from community partners has been excellent, and some students have maintained their work with the organizations.

Affordances of students' using the World Wide Web as a publishing medium in project-based learning environments

Science.gov (United States)

Bos, Nathan Daniel

This dissertation investigates the emerging affordance of the World Wide Web as a place for high school students to become authors and publishers of information. Two empirical studies lay groundwork for student publishing by examining learning issues related to audience adaptation in writing, motivation and engagement with hypermedia, design, problem-solving, and critical evaluation. Two models of student publishing on the World Wide Web were investigated over the course of two 11spth grade project-based science curriculums. In the first curricular model, students worked in pairs to design informative hypermedia projects about infectious diseases that were published on the Web. Four case studies were written, drawing on both product- and process-related data sources. Four theoretically important findings are illustrated through these cases: (1) multimedia, especially graphics, seemed to catalyze some students' design processes by affecting the sequence of their design process and by providing a connection between the science content and their personal interest areas, (2) hypermedia design can demand high levels of analysis and synthesis of science content, (3) students can learn to think about science content representation through engagement with challenging design tasks, and (4) students' consideration of an outside audience can be facilitated by teacher-given design principles. The second Web-publishing model examines how students critically evaluate scientific resources on the Web, and how students can contribute to the Web's organization and usability by publishing critical reviews. Students critically evaluated Web resources using a four-part scheme: summarization of content, content, evaluation of credibility, evaluation of organizational structure, and evaluation of appearance. Content analyses comparing students' reviews and reviewed Web documents showed that students were proficient at summarizing content of Web documents, identifying their publishing

Gradient optimization of finite projected entangled pair states

Science.gov (United States)

Liu, Wen-Yuan; Dong, Shao-Jun; Han, Yong-Jian; Guo, Guang-Can; He, Lixin

2017-05-01

Projected entangled pair states (PEPS) methods have been proven to be powerful tools to solve strongly correlated quantum many-body problems in two dimensions. However, due to the high computational scaling with the virtual bond dimension D , in a practical application, PEPS are often limited to rather small bond dimensions, which may not be large enough for some highly entangled systems, for instance, frustrated systems. Optimization of the ground state using the imaginary time evolution method with a simple update scheme may go to a larger bond dimension. However, the accuracy of the rough approximation to the environment of the local tensors is questionable. Here, we demonstrate that by combining the imaginary time evolution method with a simple update, Monte Carlo sampling techniques and gradient optimization will offer an efficient method to calculate the PEPS ground state. By taking advantage of massive parallel computing, we can study quantum systems with larger bond dimensions up to D =10 without resorting to any symmetry. Benchmark tests of the method on the J1-J2 model give impressive accuracy compared with exact results.

Observing Pair-Work Task in an English Speaking Class

Directory of Open Access Journals (Sweden)

Diana Achmad

2014-01-01

Full Text Available This paper reports on students’ pair-work interactions to develop their speaking skills in an ELT classroom which consisted of international learners. A number of 16 learners of intermediate proficiency with IELTS score band 5.5 were observed. The teacher had paired those he considered among them to be the more competent ones (hereafter, stronger with the less competent ones (hereafter, weaker; therefore, eight pairs were observed during the lesson. The task given to the students was to express ‘Agree and Disagree’ in the context of giving opinions related to social life. Based on the observations, the task was successfully implemented by six pairs; thus, the two others faced some problems. From the first pair, it was seen that the stronger student had intimated the weaker one into speaking during the task. The other pair, who was both of the same native, did not converse in English as expected and mostly used their native language to speak with one another presumably due to respect from the stronger student towards the weaker one. In situations like this, when pair-work becomes unproductive, rotating pairs is recommended to strengthen information sharing and assigning roles to avoid a student from taking over the activity from his or her pair. In conclusion, pairing international learners with mixed speaking proficiency by teachers must be conducted as effectively as possible by initially identifying their ability and learning culture to profoundly expand the students’ language resources.

2011-12-01

Computer simulations for minds-on learning with "Project Spectra!" How do we gain information about the Sun? How do we know Mars has CO2 or that Enceladus has H2O geysers? How do we use light in astronomy? These concepts are something students and educators struggle with because they are abstract. Using simulations and computer interactives (games) where students experience and manipulate the information makes concepts accessible. Visualizing lessons with multi-media solidifies understanding and retention of knowledge and is completely unlike its paper-and-pencil counterpart. Visualizations also enable teachers to forgo purchasing expensive laboratory equipment. "Project Spectra!" is a science and engineering program that uses computer-based Flash interactives to expose students to astronomical spectroscopy and actual data in a way that is not possible with traditional in-class activities. To engage students in "Project Spectra!", students are given a mission, which connects them with the research at hand. Missions range from exploring remote planetary atmospheres and surfaces, experimenting with the Sun using different filters, or analyzing the soil of a remote planet. Additionally, students have an opportunity to learn about NASA missions, view movies, and see images connected with their mission, which is something that is not practical to do during a typical paper-and-pencil activity. Since students can choose what to watch and explore, the interactives accommodate a broad range of learning styles. Students can go back and forth through the interactives if they've missed a concept or wish to view something again. In the end, students are asked critical thinking questions and conduct web-based research. These interactives complement in-class Project SPECTRA! activities exploring applications of the electromagnetic spectrum.

Improved contraction schemes for projected entangled pair states

Energy Technology Data Exchange (ETDEWEB)

Lubasch, Michael; Cirac, Juan Ignacio; Banuls, Mari-Carmen [Max Planck Institute of Quantum Optics, Hans-Kopfermann-Strasse 1, 85748 Garching (Germany)

2013-07-01

Projected Entangled Pair States (PEPS) represent the natural generalization of Matrix Product States (MPS) in higher dimensions. The strength of MPS in the numerical simulation of 1D quantum many-body systems is well established, as they are the variational class of states underlying the Density Matrix Renormalization Group and the latter is nowadays considered numerically exact for systems comprising hundreds of quantum particles. In algorithms based on MPS or PEPS, the bond dimension D of the state determines the number of variational parameters and the computational cost. While bond dimensions on the order of hundreds and thousands are feasible with MPS, standard 2D PEPS algorithms are limited to values in the range 2 to 6 due to the much worse scaling of the computational cost with D. Recently, a new algorithm based on an alternative contraction has been proposed that reduces this cost significantly. It resorts to the single-layer picture where the contraction is done in ket and bra separately. We investigate the advantages and disadvantages of this algorithm which can be understood in terms of the PEPS's boundary approximation.

Yanamandra-Fisher, P. A.

2015-12-01

Student to Scientist (S2S), provides pathways for observational and research tools for K-12 and undergraduate students to improve science proficiency through conducting real scientific observations. Our approach lies in the integration of professional and amateur astronomers, educators, students, and communicators to identify multiple paths for the student to become a scientist. I report on the ensuing project, also known as the PACA Project, which is an ecosystem of various activities that take advantage of the social media and immediate connectivity amongst amateur astronomers worldwide and that can be galvanized to participate in a given observing campaign. The PACA Project has participated in organized campaigns such as NASA Comet ISON Observing Campaign in 2013; NASA Comet Integrated Observations Campaign to observe Comet Siding Spring as it flew by very close to Mars on 19 October 2014. Currently the PACA Project is involved in the Ground-based Amateur campaign to observer ESA/Rosetta mission's target, 67P/Churyumov-Gerasimenko (CG) that is en route to its perihelion on 13 August 2015 (at the time of abstract submission). The PACA Project provides access to the professional community and the student/educator and informal/public communities via various social media like Facebook, Twitter, Flickr, Pinterest, Vimeo, Google+. With the popularity of mobile platforms and instant connections with other peers globally, the multi-faceted social universe has become a vital part of engagement of multiple communities. The PACA project currently has initiated a Comet Tails and Disconnection Events campaign to relate to the changing solar wind conditions. Other PACA projects include Saturn Solstice 2017 and outreach projects with Astroproject (India). These and other citizen-science enabled activities and their integration with S2S project will be discussed.

Integrating Project-Based Service-Learning into an Advanced Environmental Chemistry Course

Science.gov (United States)

Draper, Alison J.

2004-02-01

In an advanced environmental chemistry course, the inclusion of semester-long scientific service projects successfully integrated the research process with course content. Each project involved a unique community-based environmental analysis in which students assessed an aspect of environmental health. The projects were due in small pieces at even intervals, and students worked independently or in pairs. Initially, students wrote a project proposal in which they chose and justified a project. Following a literature review of their topic, they drafted sampling and analysis plans using methods in the literature. Samples were collected and analyzed, and all students assembled scientific posters describing the results of their study. In the last week of the semester, the class traveled to a regional professional meeting to present the posters. In all, students found the experience valuable. They learned to be professional environmental chemists and learned the value of the discipline to community health. Students not only learned about their own project in depth, but they were inspired to learn textbook material, not for an exam, but because it helped them understand their own project. Finally, having a community to answer to at the end of the project motivated students to do careful work.

Using movies has been accepted worldwide as a tool to help students learn medical professionalism. In the second year, a group of medical students conducted the "Cinemeducation" project to promote professionalism in the "Medical Ethics and Critical Thinking" course. Five movies with professionalism issues were screened with 20-30 students attending each session. After the show, participants then were asked to reflect on what they had learned in terms of professionalism. Two students led group discussion emphasizing questioning and argumentation for 60 min. Additional learning issues emerging from each session were also explored in more depth and arranged into a report. In the Cinemeducation Project, medical students have learned five main ethical issues in each film, which were the doctor-patient relationship, informed consent and clinical trials in patients, management of genetic disorders, patient management, and brain death and organ transplantation. In addition to issues of professionalism, they also developed critical thinking and moral reasoning skills. Using a case-based scenario in movies has proven to be an effective and entertaining method of facilitating students with learning on professionalism.

Kelsch, Michael P; Werremeyer, Amy B

2011-02-10

To implement and assess a required public health poster project in a doctor of pharmacy (PharmD) program. Third-year PharmD students collaborated in pairs to research a public health topic relating to pharmacy practice. Each student group prepared an informational poster, while receiving feedback from a faculty mentor at each stage of the project. The students presented their completed posters at a statewide pharmacy conference. Faculty members evaluated the posters with a grading rubric, and students completed a survey instrument that assessed the overall experience. In general, faculty members rated the class highly across all domains of the grading rubric. The class generally agreed that the poster project increased their awareness of public health issues related to pharmacy practice, overall knowledge of public health, and presentation skills. The implementation of a poster project was well received by students and faculty members as an effective method for enhancing public health instruction in the PharmD program at North Dakota State University.

University-Level Research Projects for High School Students

McConnell, Mark L.

2000-01-01

The goal of this project was to provide an opportunity for high school students to participate in university-level research projects. In this case, students from Pinkerton Academy (Derry, New Hampshire) were invited to participate in efforts to catalog data from the COMPTEL experiment on NASA's Compton Gamma-Ray Observatory (CGRO). These activities were part of a senior level honors course at Pinkerton. Although the success of this particular program was rather limited, we feel that the general concept is a sound one. In principle, the concept of partnerships between local schools and university researchers is one that could be especially attractive to soft money researchers. Programs can be carefully designed to benefit both the students and the research program.

Exploring Pair Programming Benefits for MIS Majors

Full Text Available Pair programming is a collaborative programming practice that places participants in dyads, working in tandem at one computer to complete programming assignments. Pair programming studies with Computer Science (CS and Software Engineering (SE majors have identified benefits such as technical productivity, program/design quality, academic performance, and increased satisfaction for their participants. In this paper, pair programming is studied with Management Information Systems (MIS majors, who (unlike CS and SE majors taking several programming courses typically take only one programming course and often struggle to develop advanced programming skills within that single course. The researchers conducted two pair programming experiments in an introductory software development course for MIS majors over three semesters to determine if pair programming could enhance learning for MIS students. The program results, researchers’ direct observations, and participants’ responses to a survey questionnaire were analyzed after each experiment. The results indicate that pair programming appears to be beneficial to MIS students’ technical productivity and program design quality, specifically the ability to create programs using high-level concepts. Additionally, results confirmed increased student satisfaction and reduced frustration, as the pairs worked collaboratively to produce a program while actively communicating and enjoying the process.

With growing interconnectivity of healthcare systems worldwide and increased immigration, inappropriate cultural and role assumptions are often seen when cultures clash within a country or when there is practice across country boundaries in times of disaster and during international travel. To increase students' multicultural awareness and work experiences abroad, the authors describe a 7-school, 5-country international student exchange project. The authors also share the students' evaluations of their experiences as they are challenged to erase boundaries and embrace nursing across countries. Participating faculty describe the process, challenges, and keys to success found in creating and living this international project. Students involved in the exchange process evaluate the learning opportunities and challenges and the joy of coming together as newfound colleagues and friends.

In many physical scenarios, close relations between the bulk properties of quantum systems and theories associated to their boundaries have been observed. In this work, we provide an exact duality mapping between the bulk of a quantum spin system and its boundary using Projected Entangled Pair States (PEPS). This duality associates to every region a Hamiltonian on its boundary, in such a way that the entanglement spectrum of the bulk corresponds to the excitation spectrum of the boundary Hamiltonian. We study various models and find that a gapped bulk phase with local order corresponds to a boundary Hamiltonian with local interactions, whereas critical behavior in the bulk is reflected on a diverging interaction length of the boundary Hamiltonian. Furthermore, topologically ordered states yield non-local Hamiltonians. As our duality also associates a boundary operator to any operator in the bulk, it in fact provides a full holographic framework for the study of quantum many-body systems via their boundary.

also found that some of the positive and negative characteristics were linked to the students due to their gender. Through the argument that female students talk too much or are having difficulty in coping with criticism, male students refused to cooperate with the female students. Conversely, the male...... students, who were few in the educations I studied, were quite in demand. For me it was very surprising to find these stereotypical perceptions and reasoning among young people in contemporary (and quite progressive) Danish educations. And the question is what it means for the students’ possibilities...... of completing their education. In my presentation I will unfold and discuss the ways in which the students attributed and disclaimed legitimacy to each other qua gender and thus how gender was linked to the relationship between inclusion and exclusion in the student project groups....

Project Career is an interprofessional five-year development project designed to improve the employment success of undergraduate college and university students with traumatic brain injury (TBI). The case study information was collected and synthesized by the project's Technology and Employment Coordinators (TECs) at each of the project's three university sites. The project's evaluation is occurring independently through JBS International, Inc. Five case studies are presented to provide an understanding of student participants' experiences within Project Career. Each case study includes background on the student, engagement with technology, vocational supports, and interactions with his/her respective TEC. A qualitative analysis from the student's case notes is provided within each case study, along with a discussion of the overall qualitative analysis. Across all five students, the theme Positive Outcomes was mentioned most often in the case notes. Of all the different type of challenges, Cognitive Challenges were most often mentioned during meetings with the TECs, followed by Psychological Challenges, Physical Challenges, Other Challenges, and Academic Challenges, respectively. Project Career is providing academic enrichment and career enhancement that may substantially improve the unsatisfactory employment outcomes that presently await students with TBI following graduation.

Mathematics authentic assessment is a form of meaningful measurement of student learning outcomes for the sphere of attitude, skill and knowledge in mathematics. The construction of attitude, skill and knowledge achieved through the fulfilment of tasks which involve active and creative role of the students. One type of authentic assessment is student mini projects, started from planning, data collecting, organizing, processing, analysing and presenting the data. The purpose of this research is to learn the process of using authentic assessments on statistics learning which is conducted by teachers and to discuss specifically the use of mini projects to improving students’ learning in the school of Surakarta. This research is an action research, where the data collected through the results of the assessments rubric of student mini projects. The result of data analysis shows that the average score of rubric of student mini projects result is 82 with 96% classical completeness. This study shows that the application of authentic assessment can improve students’ mathematics learning outcomes. Findings showed that teachers and students participate actively during teaching and learning process, both inside and outside of the school. Student mini projects also provide opportunities to interact with other people in the real context while collecting information and giving presentation to the community. Additionally, students are able to exceed more on the process of statistics learning using authentic assessment.

Statistical deprojection of galaxy pairs

Science.gov (United States)

Nottale, Laurent; Chamaraux, Pierre

2018-06-01

Aims: The purpose of the present paper is to provide methods of statistical analysis of the physical properties of galaxy pairs. We perform this study to apply it later to catalogs of isolated pairs of galaxies, especially two new catalogs we recently constructed that contain ≈1000 and ≈13 000 pairs, respectively. We are particularly interested by the dynamics of those pairs, including the determination of their masses. Methods: We could not compute the dynamical parameters directly since the necessary data are incomplete. Indeed, we only have at our disposal one component of the intervelocity between the members, namely along the line of sight, and two components of their interdistance, i.e., the projection on the sky-plane. Moreover, we know only one point of each galaxy orbit. Hence we need statistical methods to find the probability distribution of 3D interdistances and 3D intervelocities from their projections; we designed those methods under the term deprojection. Results: We proceed in two steps to determine and use the deprojection methods. First we derive the probability distributions expected for the various relevant projected quantities, namely intervelocity vz, interdistance rp, their ratio, and the product rp v_z^2, which is involved in mass determination. In a second step, we propose various methods of deprojection of those parameters based on the previous analysis. We start from a histogram of the projected data and we apply inversion formulae to obtain the deprojected distributions; lastly, we test the methods by numerical simulations, which also allow us to determine the uncertainties involved.

During the last decade 'labwork' courses at university level have changed significantly. The beginning of this development was indicated and partly initiated by the EU-project 'Labwork in Science Education' funded by the European Community (1999-2001). The present special issue of the European Journal of Physics focuses on a multitude of different aspects of this process. The aim of this publication is to improve the exchange of experience and to promote this important trend. In physics research labs a silent revolution has taken place. Today the personal computer is omnipresent. It controls the experiment via stepping motors, piezo-microdrives etc, it monitors all parameters and collects the experimental data with the help of smart sensors. In particular, computer-based modern scanning and imaging techniques open the possibility of creating really new types of experiments. The computer allows data storage and processing on the one hand and simulation and modelling on the other. These processes occur in parallel or may even be interwoven. The web plays an important role in modern science for inquiry, communication, cooperation and publication. Traditional labwork courses do not prepare students for the many resulting demands. Therefore it is necessary to redefine the learning targets and to reconsider the learning methods. Two contributions show exemplarily how modern experimental devices could find their way into students' labs. In the article 'Infrared thermal imaging as a tool in university physics education' by Klaus-Peter Möllmann and Michael Vollmer we can see that infrared thermal imaging is a valuable tool in physics education at university level. It can help to visualize and thereby enhance understanding of physical phenomena of mechanics, thermal physics, electromagnetism, optics and radiation physics. The contribution 'Using Peltier cells to study solid-liquid-vapor transitions and supercooling' by Giacomo Torzo, Isabella Soletta and Mario Branca proves

Creative thinking was an important learning skill in the 21st Century via learning and innovation to promote students' creative thinking and working with others and to construct innovation. This is one of the important skills that determine the readiness of the participants to step into the complex society. The purposes of this research were 1) to compare the learning achievement of students after using basic character design and animation concepts using the flipped learning and project-based learning and 2) to make a comparison students' creative thinking between pretest and posttest. The populations were 29 students in Multimedia Technology program at Thepsatri Rajabhat University in the 2nd semester of the academic year 2016. The experimental instruments were lesson plans of basic character design and animation concepts using the flipped learning and project based learning. The data collecting instrument was creative thinking test. The data were analyzed by the arithmetic mean, standard deviation and The Wilcoxon Matched Pairs Signed-Ranks Test. The results of this research were 1) the learning achievement of students were statistically significance of .01 level and 2) the mean score of student's creativity assessment were statistically significance of .05 level. When considering all of 11 KPIs, showed that respondents' post-test mean scores higher than pre-test. And 5 KPIs were statistically significance of .05 level, consist of Originality, Fluency, Elaboration, Resistance to Premature Closure, and Intrinsic Motivation. It's were statistically significance of .042, .004, .049, .024 and .015 respectively. And 6 KPIs were non-statistically significant, include of Flexibility, Tolerance of Ambiguity, Divergent Thinking, Convergent Thinking, Risk Taking, and Extrinsic Motivation. The findings revealed that the flipped learning and project based learning provided students the freedom to simply learn on their own aptitude. When working together with project

The Lifestyle Project: Challenging Students to Redefine their Approach to Resource Use (Invited)

Science.gov (United States)

Kirk, K.

2009-12-01

The Lifestyle Project is a way for students to learn about environmental impacts by changing their own lifestyles. It is a three-week exercise during which students reduce their energy use, waste output and water use by changing the way they live from day to day. The project has fairly rigid parameters, allowing students to achieve a gradual but definitive change in their everyday habits. Students begin by taking baseline measurements of their resource use, and then they select three different areas in which they are interested in reducing their environmental impact. Within each area there are clearly defined rules that provide a structured means for achieving significant changes. Each week the project becomes more rigorous, because students will have to meet the requirements more frequently. They write about their experiences in journals, which are incredibly insightful and illustrate just how profoundly the project affects them. The Lifestyle Project has been used across several campuses and in many educational settings such as traditional courses, online courses and in informal settings. Its strength lies in allowing students to quantify and modify their own use of resources, then compare their personal reductions to what could be applied in a larger population. This helps them apply and personalize many of the concepts addressed in courses about environmental geology, climate change, or energy resources. The incremental nature of the project allows students several opportunities to practice new behaviors, so that they become adept at using far fewer resources than they thought would be possible. Results from the Lifestyle Project indicate that students save significant amounts of energy, on the order of 1 to 2 million BTUs per day. Journal reflections illustrate a corresponding shift in students’ personal awareness of their use of resources and the repercussions of their daily decisions. Although many students find the project frustrating at first, after

A Dynamic Multi-Projection-Contour Approximating Framework for the 3D Reconstruction of Buildings by Super-Generalized Optical Stereo-Pairs.

Science.gov (United States)

Yan, Yiming; Su, Nan; Zhao, Chunhui; Wang, Liguo

2017-09-19

In this paper, a novel framework of the 3D reconstruction of buildings is proposed, focusing on remote sensing super-generalized stereo-pairs (SGSPs). As we all know, 3D reconstruction cannot be well performed using nonstandard stereo pairs, since reliable stereo matching could not be achieved when the image-pairs are collected at a great difference of views, and we always failed to obtain dense 3D points for regions of buildings, and cannot do further 3D shape reconstruction. We defined SGSPs as two or more optical images collected in less constrained views but covering the same buildings. It is even more difficult to reconstruct the 3D shape of a building by SGSPs using traditional frameworks. As a result, a dynamic multi-projection-contour approximating (DMPCA) framework was introduced for SGSP-based 3D reconstruction. The key idea is that we do an optimization to find a group of parameters of a simulated 3D model and use a binary feature-image that minimizes the total differences between projection-contours of the building in the SGSPs and that in the simulated 3D model. Then, the simulated 3D model, defined by the group of parameters, could approximate the actual 3D shape of the building. Certain parameterized 3D basic-unit-models of typical buildings were designed, and a simulated projection system was established to obtain a simulated projection-contour in different views. Moreover, the artificial bee colony algorithm was employed to solve the optimization. With SGSPs collected by the satellite and our unmanned aerial vehicle, the DMPCA framework was verified by a group of experiments, which demonstrated the reliability and advantages of this work.

Fisher, Nick

2002-09-01

Physics students at Rugby School follow the Salters Horners A-level course, which involves working on a two-week practical project of their own choosing. Pupils often misunderstand the concepts of accuracy and reliability, believing, for example, that repeating readings makes them more accurate and more reliable, whereas all it does is help to check repeatability. The course emphasizes the ideas of checking anomalous points, improving accuracy and making readings more sensitive. This article describes how we teach pupils in preparation for their projects. Based on many years of running such projects, much of this material is from a short booklet that we give out to pupils, when we train them in practical project skills.

Which Type of Inquiry Project Do High School Biology Students Prefer: Open or Guided?

Science.gov (United States)

Sadeh, Irit; Zion, Michal

2012-10-01

In teaching inquiry to high school students, educators differ on which method of teaching inquiry is more effective: Guided or open inquiry? This paper examines the influence of these two different inquiry learning approaches on the attitudes of Israeli high school biology students toward their inquiry project. The results showed significant differences between the two groups: Open inquiry students were more satisfied and felt they gained benefits from implementing the project to a greater extent than guided inquiry students. On the other hand, regarding documentation throughout the project, guided inquiry students believed that they conducted more documentation, as compared to their open inquiry peers. No significant differences were found regarding `the investment of time', but significant differences were found in the time invested and difficulties which arose concerning the different stages of the inquiry process: Open inquiry students believed they spent more time in the first stages of the project, while guided inquiry students believed they spent more time in writing the final paper. In addition, other differences were found: Open inquiry students felt more involved in their project, and felt a greater sense of cooperation with others, in comparison to guided inquiry students. These findings may help teachers who hesitate to teach open inquiry to implement this method of inquiry; or at least provide their students with the opportunity to be more involved in inquiry projects, and ultimately provide their students with more autonomy, high-order thinking, and a deeper understanding in performing science.

Full Text Available Abstract Cooperative learning is learning that requires students to be responsible for himself and his group are responsible for. With cooperative learning students will more easily find and understand difficult concepts if they were in discussions with his students regularly work in groups to help each other in solving complex problems. In cooperative learning are learning techniques of the type of think-pair-share. Type of cooperative learning model think-pair-share it has the advantage that students can be a lot of time to think, respond, and help each other, the teacher only to deliver the material briefly, then ask a question, then the teacher wants students to think more deeply about the material that has been described and experienced. This technique can encourage students to enthusiastic in working together, and by applying a type of cooperative learning model think-pair-share is expected to better learning outcomes for students who learn on their own. Keywords: Type of cooperative learning model think-pair-share, learning outcomes

The U.S. Department of Energy (DOE) is very concerned about the lack of understanding of basic science. Increasingly, critical decisions regarding the use of energy, technology, and the environment are being made. A well-educated and science-literate public is vital to the success of these decisions. Science education and school instruction are integral parts of the DOE's public outreach program on the Yucca Mountain Site Characterization Project (YMP). Project staff and scientists speak to elementary, junior high, high school, and university students, accepting all speaking invitations. The objectives of this outreach program include the following: (1) educating Nevada students about the concept of a high-level nuclear waste repository; (2) increasing awareness of energy and environmental issues; (3) helping students understand basic concepts of earth science and geology in relation to siting a potential repository; and (4) giving students information about careers in science and engineering

This article describes a synergistic two-semester writing sequence for biochemistry courses. In the first semester, students select a putative protein and are tasked with researching their protein largely through bioinformatics resources. In the second semester, students develop original ideas and present them in the form of a research grant proposal. Both projects involve multiple drafts and peer review. The complementarity of the projects increases student exposure to bioinformatics and literature resources, fosters higher-order thinking skills, and develops teamwork and communication skills. Student feedback and responses on perception surveys demonstrated that the students viewed both projects as favorable learning experiences. © 2015 The International Union of Biochemistry and Molecular Biology.

Full Text Available The result of teaching-learning by using Think Pair Share method can improve the students’ activities. It can be seen from the steps to apply the Think Pair Share method that focused on student-centre. Think pair share learning has a simple structure, as a basic of the development ‘cooperative class’ which can help the learning process actively for students, thus it can improve the students’ study result. Students actively can show their ability to discuss and share and express the answer of questions in front of the class. Teachers in teaching- learning process by using think pair share method acted as mediator, facilitator and motivator. It is different with conventional teaching-learning process which focused on teacher-center. Students were passive in teaching-learning process. Students tended to be bored if the teacher was lack to give motivation for students to pay attention to the teacher. Thus, the using of think pair share would be more effective if we see on how the students interaction in learning process.

STEM-related, Student-led Service Learning / Community Engagement Projects: Examples and Benefits

Science.gov (United States)

Swap, R. J.; Wayland, K.

2015-12-01

Field-based, STEM-related service learning / community engagement projects present an opportunity for undergraduate students to demonstrate proficiencies related to the process of inquiry. These proficiencies include: appreciation of the larger project context, articulation of an informed question/hypothesis, project proposal development, interdisciplinary collaboration, project management (including planning, implementation reconfiguration and synthesis) and lastly the generation and handing off of acquired knowledge. Calls for these types of proficiencies have been expressed by governmental, non-governmental as well as the private sector. Accordingly, institutions of higher learning have viewed such activities as opportunities for enriching the learning experience for undergraduate students and for making such students more marketable, especially those from STEM-related fields. This institutional interest has provided an opportunity to support and expand field-based learning. Here we present examples of student-led/faculty-mentored international service learning and community engagement projects along the arc of preparation, implementation and post-field process. Representative examples that draw upon environmental science and engineering knowledge have been selected from more than 20 international undergraduate student projects over past decade and include: slow-sand water filtration, rainwater harvesting, methane biodigesters, water reticulation schemes and development and implementation of rocket stoves for communal cooking. We discuss these efforts in terms of the development of the aforementioned proficiencies, the utility of such proficiencies to the larger enterprise of STEM and the potential for transformative student learning outcomes. We share these experiences and lessons learned with the hope that others may intelligently borrow from our approach in a manner appropriate for their particular context.

Ronald O. Ocampo

2015-12-01

Full Text Available Traditional classroom situation where students are taught predominantly of lecture-discussion method put the classroom in a mathophobic atmosphere. Oftentimes, students exposed to this classroom atmosphere lead to math anxiety and eventually hate the subject and the teacher. Addressing this, varied interactive strategies to create an atmosphere of discourse has been developed and promoted. The use of instructional games has been viewed as one strategy that promotes active learning inside the classroom. Instructional games support constructivist learning and social learning. This study is aimed at developing, validating and evaluating card pairing games for specific topics in Math 8. The Research and Development model ( R& D was used. The card pairing games was validated by subject experts and experts in developing games. In evaluating the card pairing games, the Quasi-Experimental Pretest-Posttest design was used. There are six card pairing games developed for specific topics in Math 8; the card pairing game is highly valid based on the result of the validation; Students exposed to card pairing game become more intact (homogeneous; Students exposed to card games enhance academic performance. It is recommended to test the effectiveness of card pairing games to other group of students; Encourage math teachers to use the developed math card pairing games for classroom instruction; Develop other card pairing game for specific topics in math.

Although the discipline of cell biology (CB) is part of the curricula of predoctoral dental schools, students often fail to recognize its practical relevance. The aim of this study was to assess the effectiveness of a practical-theoretical project-based course in closing the gaps among CB, scientific research, and dentistry for dental students. A project-based learning course was developed with nine sequential lessons to evaluate 108 undergraduate dental students enrolled in CB classes of a Brazilian school of dentistry during 2013-16. To highlight the relevance of in vitro studies in the preclinical evaluation of dental materials at the cellular level, the students were challenged to complete the process of drafting a protocol and performing a cytocompatibility assay for a bone substitute used in dentistry. Class activities included small group discussions, scientific database search and article presentations, protocol development, lab experimentation, and writing of a final scientific report. A control group of 31 students attended only one laboratory class on the same theme, and the final reports were compared between the two groups. The results showed that the project-based learning students had superior outcomes in acknowledging the relevance of in vitro methods during biocompatibility testing. Moreover, they produced scientifically sound reports with more content on methodological issues, the relationship with dentistry, and the scientific literature than the control group (p<0.05). The project-based learning students also recognized a higher relevance of scientific research and CB to dental practice. These results suggest that a project-based approach can help contextualize scientific research in dental curricula.

Student projects in medicine: a lesson in science and ethics.

Science.gov (United States)

Edwards, Sarah J L

2009-11-01

Regulation of biomedical research is the subject of considerable debate in the bioethics and health policy worlds. The ethics and governance of medical student projects is becoming an increasingly important topic in its own right, especially in the U.K., where there are periodic calls to change it. My main claim is that there seems to be no good reason for treating student projects differently from projects led by qualified and more experienced scientists and hence no good grounds for changing the current system of ethics review. I first suggest that the educational objectives cannot be met without laying down standards of good science, whatever they may be. Weak science is unnecessary for educational purposes, and it is, in any case, unlikely to produce good researchers in the future. Furthermore, it is curious to want to change the system of ethics review specifically for students when it is the science that is at stake, and when the science now falls largely outside the ethics remit. I further show that ethics review is nevertheless important since students carry a new potential conflict of interests that warrants independent oversight which supervisory support does not offer. This potential conflict may become more morally troublesome the greater the risks to the subjects of the research, and students may impose greater risks on their subjects (relative to professional researchers) by virtue of being inexperienced, whatever the nature of the project. Pragmatic concerns may finally be allayed by organizing the current system more efficiently at critical times of the university calendar.

We carry out teaching based on optoelectronic related course group, aiming at junior students majored in Optoelectronic Information Science and Engineering. " Optoelectronic System Course Project " is product-designing-oriented and lasts for a whole semester. It provides a chance for students to experience the whole process of product designing, and improve their abilities to search literature, proof schemes, design and implement their schemes. In teaching process, each project topic is carefully selected and repeatedly refined to guarantee the projects with the knowledge integrity, engineering meanings and enjoyment. Moreover, we set up a top team with professional and experienced teachers, and build up learning community. Meanwhile, the communication between students and teachers as well as the interaction among students are taken seriously in order to improve their team-work ability and communicational skills. Therefore, students are not only able to have a chance to review the knowledge hierarchy of optics, electronics, and computer sciences, but also are able to improve their engineering mindset and innovation consciousness.

Undergraduate Research Involving Deaf and Hard-of-Hearing Students in Interdisciplinary Science Projects

Directory of Open Access Journals (Sweden)

Todd Pagano

2015-05-01

Full Text Available Scientific undergraduate research in higher education often yields positive outcomes for student and faculty member participants alike, with underrepresented students often showing even more substantial gains (academic, professional, and personal as a result of the experience. Significant success can be realized when involving deaf and hard-of-hearing (d/hh undergraduate students, who are also vastly underrepresented in the sciences, in interdisciplinary research projects. Even d/hh Associate degree level students and those in the first two years of their postsecondary careers can contribute to, and benefit from, the research process when faculty mentors properly plan/design projects. We discuss strategies, including the dissemination/communication of research results, for involving these students in research groups with different communication dynamics and share both findings of our research program and examples of successful chemical and biological research projects that have involved d/hh undergraduate students. We hope to stimulate a renewed interest in encouraging diversity and involving students with disabilities into higher education research experiences globally and across multiple scientific disciplines, thus strengthening the education and career pipeline of these students.

Peterman, Karen; Kermish-Allen, Ruth; Knezek, Gerald; Christensen, Rhonda; Tyler-Wood, Tandra

2016-12-01

This article describes Energy for ME and Going Green! Middle Schoolers Out to Save the World, two Science, Technology, Engineering, and Mathematics (STEM) education programs with the common goal of improving students' attitudes about scientific careers. The authors represent two project teams, each with funding from the National Science Foundation's ITEST program. Using different approaches and technology, both projects challenged students to use electricity monitoring system data to create action plans for conserving energy in their homes and communities. The impact of each project on students' career interests was assessed via a multi-method evaluation that included the Career Interest Questionnaire (CIQ), a measure that was validated within the context of ITEST projects and has since become one of the instruments used most commonly across the ITEST community. This article explores the extent to which the CIQ can be used to document the effects of technology-enhanced STEM educational experiences on students' career attitudes and intentions in different environments. The results indicate that the CIQ, and the Intent subscale in particular, served as significant predictors of students' self-reported STEM career aspirations across project context. Results from each project also demonstrated content gains by students and demonstrated the impact of project participation and gender on student outcomes. The authors conclude that the CIQ is a useful tool for providing empirical evidence to document the impact of technology-enhanced science education programs, particularly with regard to Intent to purse a STEM career. The need for additional cross-project comparison studies is also discussed.

Science.gov (United States)

Lin, Chien-Liang

2018-02-01

This study sought to develop a self-report instrument to be used in the assessment of the project competences of college students engaged in online project-based learning. Three scales of the KIPSSE instrument developed for this study, namely, the knowledge integration, project skills, and self-efficacy scales, were based on related theories and the analysis results of three project advisor interviews. Those items of knowledge integration and project skill scales focused on the integration of different disciplines and technological skills separately. Two samples of data were collected from information technology-related courses taught with an online project-based learning strategy over different semesters at a college in southern Taiwan. The validity and reliability of the KIPSSE instrument were confirmed through item analysis and confirmatory factor analysis using structural equation modeling of two samples of students' online response sets separately. The Cronbach's alpha reliability coefficient for the entire instrument was 0.931; for each scale, the alpha ranged from 0.832 to 0.907. There was also a significant correlation ( r = 0.55, p < 0.01) between the KIPSSE instrument results and the students' product evaluation scores. The findings of this study confirmed the validity and reliability of the KIPSSE instrument. The confirmation process and related implications are also discussed.

Kac's question, planar isospectral pairs and involutions in projective space: II. Classification of generalized projective isospectral data

International Nuclear Information System (INIS)

Thas, Koen

2006-01-01

In Am. Math. Monthly (73 1-23 (1966)), Kac asked his famous question 'Can one hear the shape of a drum?', which was eventually answered negatively in Gordon et al (1992 Invent. Math. 110 1-22) by construction of planar isospectral pairs. Giraud (2005 J. Phys. A: Math. Gen. 38 L477-83) observed that most of the known examples can be generated from solutions of a certain equation which involves a set of involutions of an n-dimensional projective space over some finite field. He then generated all possible solutions for n = 2, when the involutions fix the same number of points. In Thas (2006 J. Phys. A: Math. Gen. 39 L385-8) we showed that no other examples arise for any other dimension, still assuming that the involutions fix the same number of points. In this paper we study the problem for involutions not necessarily fixing the same number of points, and solve the problem completely

Enhancing Teacher and Student Engagement and Understanding of Marine Science Through Classroom Citizen Science Projects

Science.gov (United States)

Goodale, T. A.

2016-02-01

Overview This paper presentation shares findings from a granted funded project that sought to expand teacher content knowledge and pedagogy within the fields of marine science and coastal resource management through the implementation of classroom citizen science projects. A secondary goal was to increase middle and high school student interest and participation in marine science and natural resources research. Background A local science & engineering fair has seen a rapid decline in secondary student participants in the past four years. Research has demonstrated that when students are a part of a system of knowledge production (citizen science) they become much more aware, involved and conscious of scientific concepts compared to traditional school laboratory and nature of science activities. This project's primary objectives were to: (a) enhance teacher content expertise in marine science, (b) enrich teacher professional learning, (c) support citizen science classroom projects and inspire student activism and marine science engagement. Methods Project goals were addressed through classroom and meaningful outdoor educational experiences that put content knowledge into field based practices. Teachers learned to apply thier expanded content knowlege through classroom citizen science projects that focus on marine resource conservation issues such as fisheries management, water quality, turtle nesting and biodiversity of coastal ecosystems. These projects would eventually become potential topics of citizen science research topics for their students to pursue. Upon completion of their professional development, participants were urged to establish student Marine Science clubs with the goal of mentoring student submissions into the local science fair. Supplemental awards were possible for the students of project participants. Findings Based on project measures participants significantly increased their knowledge and awareness of presented material marine science and

Student ownership of projects in an upper-division optics laboratory course: A multiple case study of successful experiences

Science.gov (United States)

Dounas-Frazer, Dimitri R.; Stanley, Jacob T.; Lewandowski, H. J.

2017-12-01

We investigate students' sense of ownership of multiweek final projects in an upper-division optics lab course. Using a multiple case study approach, we describe three student projects in detail. Within-case analyses focused on identifying key issues in each project, and constructing chronological descriptions of those events. Cross-case analysis focused on identifying emergent themes with respect to five dimensions of project ownership: student agency, instructor mentorship, peer collaboration, interest and value, and affective responses. Our within- and cross-case analyses yielded three major findings. First, coupling division of labor with collective brainstorming can help balance student agency, instructor mentorship, and peer collaboration. Second, students' interest in the project and perceptions of its value can increase over time; initial student interest in the project topic is not a necessary condition for student ownership of the project. Third, student ownership is characterized by a wide range of emotions that fluctuate as students alternate between extended periods of struggle and moments of success while working on their projects. These findings not only extend the literature on student ownership into a new educational domain—namely, upper-division physics labs—they also have concrete implications for the design of experimental physics projects in courses for which student ownership is a desired learning outcome. We describe the course and projects in sufficient detail that others can adapt our results to their particular contexts.

Evaluating the Effects of Virtual Pair Programming on Students’ Achievement and Satisfaction

Directory of Open Access Journals (Sweden)

Nick Zacharis

2009-09-01

Full Text Available Pair programming is a lightweight software development technique in which two programmers work together at one computer. In literature, many benefits of pair programming have been proposed, such as increased productivity, improved code quality, enhanced job satisfaction and confidence. Although pair programming provides clear pedagogical benefits, its collocation requirement and the limited time during a lab session are serious barriers in the full deployment and evaluation of this programming technique. This paper reports on a study that investigated the effectiveness of Virtual Pair Programming (VPP on student performance and satisfaction in an introductory Java course where students worked collaboratively in pairs on homework programming assignments, using online tools that integrated desktop sharing and real time communication. The results of this study support previous research findings and suggest that VPP is an effective pedagogical tool for flexible collaboration and an acceptable alternative to individual/solo programming experience, regarding productivity, code quality, academic performance and student satisfaction.

Full Text Available The ability to raise funds is a skill that most modern project managers need. While a good deal of literature exists on the strategies NGOs employ to raise funds for their operations, less attention has been paid to the strategies used by students involved in Project-Based Learning courses that often partner with NGOs. Fundraising is an important skill that not only provides students with opportunities for creativity, but also helps them develop the communication skills they will need in the work they do after they graduate.In this paper, we discuss the fundraising strategies developed by MBA students in 204 social projects completed between 2002 and 2014. The projects were done in partnership with 39 community partners in Sao Paulo, Brazil (NGOs and Public Institutions. In our study, we followed quantitative and qualitative research methods, analyzing data and documents from the projects’ databases. We identified six different fundraising strategies: organizing raffles, soliciting donations from private corporations, organizing paying events, utilizing online social networks developing crowdfunding, and soliciting individual donations.

Pair Programming as a Modern Method of Teaching Computer Science

Directory of Open Access Journals (Sweden)

Irena Nančovska Šerbec

2008-10-01

Full Text Available At the Faculty of Education, University of Ljubljana we educate future computer science teachers. Beside didactical, pedagogical, mathematical and other interdisciplinary knowledge, students gain knowledge and skills of programming that are crucial for computer science teachers. For all courses, the main emphasis is the absorption of professional competences, related to the teaching profession and the programming profile. The latter are selected according to the well-known document, the ACM Computing Curricula. The professional knowledge is therefore associated and combined with the teaching knowledge and skills. In the paper we present how to achieve competences related to programming by using different didactical models (semiotic ladder, cognitive objectives taxonomy, problem solving and modern teaching method “pair programming”. Pair programming differs from standard methods (individual work, seminars, projects etc.. It belongs to the extreme programming as a discipline of software development and is known to have positive effects on teaching first programming language. We have experimentally observed pair programming in the introductory programming course. The paper presents and analyzes the results of using this method: the aspects of satisfaction during programming and the level of gained knowledge. The results are in general positive and demonstrate the promising usage of this teaching method.

Buettner, Cynthia K; Andrews, David W; Glassman, Michael

2009-01-01

Significant involvement of students in the development and implementation of college alcohol prevention strategies is largely untested, despite recommendations by the National Institute of Alcohol Abuse and Alcoholism and others. The purpose of the Pragmatics Project was to test a student engagement model for developing and implementing alcohol intervention strategies. The Pragmatics Project involved 89 undergraduate students on a large Midwestern university campus in the design and implementation of projects focused on reducing harm associated with high-risk drinking and off-campus parties. The engagement model used an innovative course piloted in the Human Development and Family Science department. The course successfully involved both students and the community in addressing local alcohol issues. The course design described would fit well into a Master of Public Health, Community Psychology, Health Psychology, or interdisciplinary curricula as well as the service learning model, and it is applicable in addressing other health risk behaviors.

Education projects: an opportunity for student fieldwork in global health academic programs.

Science.gov (United States)

Fyfe, Molly V

2012-01-01

Universities, especially in higher-income countries, increasingly offer programs in global health. These programs provide different types of fieldwork projects, at home and abroad, including: epidemiological research, community health, and clinical electives. I illustrate how and why education projects offer distinct learning opportunities for global health program fieldwork. As University of California students, we partnered in Tanzania with students from Muhimbili University of Health and Allied Science (MUHAS) to assist MUHAS faculty with a curricular project. We attended classes, clinical rounds, and community outreach sessions together, where we observed teaching, materials used, and the learning environment; and interviewed and gathered data from current students, alumni, and health professionals during a nationwide survey. We learned together about education of health professionals and health systems in our respective institutions. On the basis of this experience, I suggest some factors that contribute to the productivity of educational projects as global health fieldwork.

Interdisciplinary Service-Learning: Building Student Competencies through the Cross-Cultural Parent Groups Project

Directory of Open Access Journals (Sweden)

Michele Belliveau

2011-03-01

Full Text Available Changing demographics and an emphasis on competency-based social work education call for innovative approaches to the delivery of curricular content. In an effort to introduce BSW students to the socio-political issues facing the local Latino immigrant community, a service-learning project was developed in collaboration with the Spanish Language Department and a local middle school. An analysis of outcomes from social work student evaluations showed that students engaged with the community and issues in new and unexpected ways. Through their engagement in a cross-cultural group project, students developed greater cultural competency, honed their group practice skills in an unfamiliar context, provided a needed service to the community, and raised their awareness about the working conditions of new immigrants as part of a developing framework for social action. Details and implications of the project as a means to build student competencies are described.

Undergraduate nursing students' perceptions of service-learning through a school-based community project.

Science.gov (United States)

Bassi, Sherry

2011-01-01

Service-learning (SL) is an experiential teaching method that combines instruction with community service, with the aim of enriching students' academic learning, interpersonal skills and sense of responsibility while making meaningful contributions to the community. However, measuring outcomes of service-learning projects is difficult. This article reports on the perceptions of 18 third-year undergraduate nursing students who took part in a pilot service-learning project targeting tobacco use in a local elementary school. Faculty members evaluated the program's outcomes by engaging students in structured reflection on the program about its relevance to their future careers as practicing professionals, especially in community-based settings. The students' perceptions were elicited through three sets of reflective assignments following the project. Findings from the reflective assignments suggest that the pilot program was successful in enhancing the students' academic, social, and personal development while building a partnership between the school of nursing and key players in the community, including school-based nurses, teachers, administrators, families, and community leaders. The author suggests that service-learning projects can help nursing students accomplish key developmental tasks of the college years (such as building their competence, autonomy, and integrity), while helping impart the skills and values they will need as they graduate and seek professional nursing roles.

Development of the NORSTAR (Norfolk Public Student Team for Acoustical Research) Project includes the definition, design, fabrication, testing, analysis, and publishing the results of an acoustical experiment. The student-run program is based on a space flight organization similar to the Viking Project. The experiment will measure the scattering transfer of momentum from a sound field to spheres in a liquid medium. It is hoped that the experimental results will shed light on a difficult physics problem - the difference in scattering cross section (the overall effect of the sound wave scattering) for solid spheres and hollow spheres of differing wall thicknesses.

In the paper API-library software developed by students of Applied and Computer Optics Department (ITMO University) for optical system design is presented. The library performs paraxial and real ray tracing, calculates 3d order (Seidel) aberration and real ray aberration of axis and non-axis beams (wave, lateral, longitudinal, coma, distortion etc.) and finally, approximate wave aberration by Zernike polynomials. Real aperture can be calculated by considering of real rays tracing failure on each surface. So far we assume optical system is centered, with spherical or 2d order aspherical surfaces. Optical glasses can be set directly by refraction index or by dispersion coefficients. The library can be used for education or research purposes in optical system design area. It provides ready to use software functions for optical system simulation and analysis that developer can simply plug into their software development for different purposes, for example for some specific synthesis tasks or investigation of new optimization modes. In the paper we present an example of using the library for development of cemented doublet synthesis software based on Slusarev's methodology. The library is used in optical system optimization recipes course for deep studying of optimization model and its application for optical system design. Development of such software is an excellent experience for students and help to understanding optical image modeling and quality analysis. This development is organized as student group joint project. We try to organize it as a group in real research and development project, so each student has his own role in the project and then use whole library functionality in his own master or bachelor thesis. Working in such group gives students useful experience and opportunity to work as research and development engineer of scientific software in the future.

Student ownership of projects in an upper-division optics laboratory course: A multiple case study of successful experiences

Directory of Open Access Journals (Sweden)

Dimitri R. Dounas-Frazer

2017-12-01

Full Text Available We investigate students’ sense of ownership of multiweek final projects in an upper-division optics lab course. Using a multiple case study approach, we describe three student projects in detail. Within-case analyses focused on identifying key issues in each project, and constructing chronological descriptions of those events. Cross-case analysis focused on identifying emergent themes with respect to five dimensions of project ownership: student agency, instructor mentorship, peer collaboration, interest and value, and affective responses. Our within- and cross-case analyses yielded three major findings. First, coupling division of labor with collective brainstorming can help balance student agency, instructor mentorship, and peer collaboration. Second, students’ interest in the project and perceptions of its value can increase over time; initial student interest in the project topic is not a necessary condition for student ownership of the project. Third, student ownership is characterized by a wide range of emotions that fluctuate as students alternate between extended periods of struggle and moments of success while working on their projects. These findings not only extend the literature on student ownership into a new educational domain—namely, upper-division physics labs—they also have concrete implications for the design of experimental physics projects in courses for which student ownership is a desired learning outcome. We describe the course and projects in sufficient detail that others can adapt our results to their particular contexts.

Coupled rolling motion: a student project in non-holonomic mechanics

International Nuclear Information System (INIS)

Janova, Jitka; Musilova, Jana; Bartos, JirI

2009-01-01

This paper presents an original undergraduate student project in theoretical mechanics: a demonstration of theory and experiment agreement inspired by a recently theoretically treated mechanical problem of coupled rolling motion of two cylinders. The problem of a mechanical system subjected to non-holonomic constraints is theoretically and numerically solved. Subsequently, the solution is quantitatively verified by a simple and inexpensive experiment, originally proposed and constructed by the authors. The comparison of results of the theoretical study with experimental output shows that there are instruments to directly verify rather abstract mathematical theories even on the undergraduate level. Moreover, combining the theoretical description of the problem with an appropriate laboratory experiment and computational procedures gives students a more complex view of the physical problem as a whole. This paper can be used by physics teachers on the undergraduate university level as an inspiration for an interesting student project. Moreover, the theoretical part of this paper itself can be used by interested intermediate students themselves as a good exercise in theoretical mechanics.

Over the last years, Projected Entangled Pair States have demonstrated great power for the study of many body systems, as they naturally describe ground states of gapped many body Hamiltonians, and suggest a constructive way to encode and classify their symmetries. The PEPS study is not only limited to global symmetries, but has also been extended and applied for local symmetries, allowing to use them for the description of states in lattice gauge theories. In this paper we discuss PEPS with a local, SU(2) gauge symmetry, and demonstrate the use of PEPS features and techniques for the study of a simple family of many body states with a non-Abelian gauge symmetry. We present, in particular, the construction of fermionic PEPS able to describe both two-color fermionic matter and the degrees of freedom of an SU(2) gauge field with a suitable truncation.

Funded in 2005-2008, by the National Science Foundation's Geoscience Education Division, the Experiential Discoveries in Geoscience Education (EDGE) project was designed to use glacier and watershed field experiences as venues for geospatial data collected by Alaska's grade 6-12 middle and high school teachers and their students. EDGE participants were trained in GIS and learned to analyze geospatial data to answer questions about the warming Alaska environment and to determine rates of ongoing glacier recession. Important emphasis of the program was the recruitment of Alaska Native students of Inupiat, Yup'ik, Athabascan, and Tlingit populations, living in both rural and urban areas around the state. Twelve of Alaska's 55 school districts have participated in the EDGE program. To engage EDGE students in the practice of scientific inquiry, each was required to carry out a semester scale research project using georeferenced data, guided by their EDGE teacher and mentor. Across Alaska students investigated several Earth systems processes including freezing conditions of lake ice; the changes in water quality in storm drains after rainfall events; movements of moose, bears, and bison across Alaskan landscapes; changes in permafrost depth in western Alaska; and the response of migrating waterfowl to these permafrost changes. Students correlated the substrate beneath their schools with known earthquake intensities; measured cutbank and coastal erosion on northern rivers and southeastern shorelines; tracked salmon infiltration of flooded logging roads; noted the changing behavior of eagles during late winter salmon runs; located good areas for the use of tidal power for energy production; tracked the extent and range of invasive plant species with warming; and the change of forests following deglaciation. Each cohort of EDGE students and teachers finished the program by attended a 3-day EDGE symposium at which students presented their research projects first in a

Full Text Available The use of social and collaborative computing has the potential of assisting learning and improving the ability to work together as part of a team. Team work is a graduate attribute that students need to acquire before transitioning from university into the workplace. The aim of this exploratory research was to provide insights into the use of social and collaborative applications by Computer Science students, and the emergent affordances student project teams have created with the use of these applications. It answers the questions: What elearning platforms or applications do students use to collaborate for team projects? What technology affordance draws students to use these applications? This study adopts affordance theory as the theoretical framework. Two types of content analysis: conventional content analysis and summative content analysis were used to analyse the data. Data was gathered using a pre-designed questionnaire with the teams during the first semester of 2016. Findings show that the university’s elearning platform is utilised for some of their courses; however students seem to prefer free and open source platforms. Student project teams used applications such as WhatsApp, Telegram, Dropbox, Google Drive, Google Docs, as well as email messages, to work jointly, and were successfully able to complete their team projects. Four types of technology affordances: communicative-affordance, document share-affordance, course resource-affordance, and integrity-affordance, were identified as being relevant.

School science students can benefit greatly from participation in student-directed, open-ended scientific inquiry projects. For various possible reasons, however, students tend not to be engaged in such inquiries. Among factors that may limit their opportunities to engage in open-ended inquiries of their design are teachers' conceptions about science. To explore possible relationships between teachers' conceptions about science and the types of inquiry activities in which they engage students, instrumental case studies of five secondary science teachers were developed, using field notes, repertory grids, samples of lesson plans and student activities, and semistructured interviews. Based on constructivist grounded theory analysis, participating teachers' tendencies to promote student-directed, open-ended scientific inquiry projects seemed to correspond with positions about the nature of science to which they indicated adherence. A tendency to encourage and enable students to carry out student-directed, open-ended scientific inquiry projects appeared to be associated with adherence to social constructivist views about science. Teachers who opposed social constructivist views tended to prefer tight control of student knowledge building procedures and conclusions. We suggest that these results can be explained with reference to human psychological factors, including those associated with teachers' self-esteem and their relationships with knowledge-building processes in the discipline of their teaching.

Motivating nonscience majors in science and mathematics studies became one of the most interesting and important challenges in contemporary science and mathematics education. Therefore, designing and studying a learning environment, which enhances students' motivation, is an important task. This experimental study sought to explore the implications of student autonomy in topic choice in a project-based Physical Science Course for nonscience majors' on students' motivational orientation. It also suggested and tested a model explaining motivational outcomes of project-based learning environment through increased student ownership of science projects. A project, How Things Work, was designed and implemented in this study. The focus of the project was application of physical science concepts learned in the classroom to everyday life situations. Participants of the study (N = 59) were students enrolled in three selected sections of a Physical Science Course, designed to fulfill science requirements for nonscience majors. These sections were taught by the same instructor over a period of an entire 16-week semester at a large public research university. The study focused on four main variables: student autonomy in choosing a project topic, their motivational orientation, student ownership of the project, and the interest in the project topic. Achievement Goal Orientation theory became the theoretical framework for the study. Student motivational orientation, defined as mastery or performance goal orientation, was measured by an Achievement Goal Orientation Questionnaire. Student ownership was measured using an original instrument, Ownership Measurement Questionnaire, designed and tested by the researchers. Repeated measures yoked design, ANOVA, ANCOVA, and multivariate regression analysis were implemented in the study. Qualitative analysis was used to complement and verify quantitative results. It has been found that student autonomy in the project choice did not make a

Infinite projected entangled-pair state algorithm for ruby and triangle-honeycomb lattices

Jahromi, Saeed S.; Orús, Román; Kargarian, Mehdi; Langari, Abdollah

The infinite projected entangled-pair state (iPEPS) algorithm is one of the most efficient techniques for studying the ground-state properties of two-dimensional quantum lattice Hamiltonians in the thermodynamic limit. Here, we show how the algorithm can be adapted to explore nearest-neighbor local Hamiltonians on the ruby and triangle-honeycomb lattices, using the corner transfer matrix (CTM) renormalization group for 2D tensor network contraction. Additionally, we show how the CTM method can be used to calculate the ground-state fidelity per lattice site and the boundary density operator and entanglement entropy (EE) on an infinite cylinder. As a benchmark, we apply the iPEPS method to the ruby model with anisotropic interactions and explore the ground-state properties of the system. We further extract the phase diagram of the model in different regimes of the couplings by measuring two-point correlators, ground-state fidelity, and EE on an infinite cylinder. Our phase diagram is in agreement with previous studies of the model by exact diagonalization.

Investigation of the chiral antiferromagnetic Heisenberg model using projected entangled pair states

2017-09-01

A simple spin-1/2 frustrated antiferromagnetic Heisenberg model (AFHM) on the square lattice—including chiral plaquette cyclic terms—was argued [A. E. B. Nielsen, G. Sierra, and J. I. Cirac, Nat. Commun. 4, 2864 (2013), 10.1038/ncomms3864] to host a bosonic Kalmeyer-Laughlin (KL) fractional quantum Hall ground state [V. Kalmeyer and R. B. Laughlin, Phys. Rev. Lett. 59, 2095 (1987), 10.1103/PhysRevLett.59.2095]. Here, we construct generic families of chiral projected entangled pair states (chiral PEPS) with low bond dimension (D =3 ,4 ,5 ) which, upon optimization, provide better variational energies than the KL Ansatz. The optimal D =3 PEPS exhibits chiral edge modes described by the Wess-Zumino-Witten SU(2) 1 model, as expected for the KL spin liquid. However, we find evidence that, in contrast to the KL state, the PEPS spin liquids have power-law dimer-dimer correlations and exhibit a gossamer long-range tail in the spin-spin correlations. We conjecture that these features are genuine to local chiral AFHM on bipartite lattices.

Students Perceptions of Excellence in Landscape Architecture Studio Projects: A UNSW Perspective

2004-06-01

Full Text Available This paper describes an action-research project undertaken to explore teaching and learning in the design studio in the Faculty of the Built Environment (FBE, University of New South Wales, Sydney. The research project involved three undergraduate design programmes (architecture, interior architecture and landscape architecture within the FBE, however this paper will focus only on the findings related to the Bachelor of Landscape Architecture (BLArch programme. The studio is at the core of the design-based curriculum for the landscape architecture degree. This setting nurtures and encourages students to demonstrate a range of capabilities and attributes expected in professional practice. Design projects are complex, integrated assessment tasks. While design teachers use criteria to assess knowledge and skills, students often feel the judgement of overall design project excellence is based on subjective interpretation. There is also concern about the effectiveness of design teaching across the studios. Specifically, the study identified students' perceptions of what constitutes the mark of High Distinction (HD and characteristics of the ideal design teacher. This paper does not present a discourse analysis of the theoretical framework and concepts of the research project. That material is presented in previous and subsequent publications (Corkery et al, 2003.

Topological Nodal Cooper Pairing in Doped Weyl Metals

Science.gov (United States)

Li, Yi; Haldane, F. D. M.

2018-02-01

We generalize the concept of Berry connection of the single-electron band structure to that of a two-particle Cooper pairing state between two Fermi surfaces with opposite Chern numbers. Because of underlying Fermi surface topology, the pairing Berry phase acquires nontrivial monopole structure. Consequently, pairing gap functions have topologically protected nodal structure as vortices in the momentum space with the total vorticity solely determined by the pair monopole charge qp. The nodes of gap function behave as the Weyl-Majorana points of the Bogoliubov-de Gennes pairing Hamiltonian. Their relation with the connection patterns of the surface modes from the Weyl band structure and the Majorana surface modes inside the pairing gap is also discussed. Under the approximation of spherical Fermi surfaces, the pairing symmetry are represented by monopole harmonic functions. The lowest possible pairing channel carries angular momentum number j =|qp|, and the corresponding gap functions are holomorphic or antiholomorphic functions on Fermi surfaces. After projected on the Fermi surfaces with nontrivial topology, all the partial-wave channels of pairing interactions acquire the monopole charge qp independent of concrete pairing mechanism.

There is a long history of cooperation between students at the University of Colorado, Boulder and professional engineers and scientists at LASP, which has led to many successful space missions with direct student involvement. The recent student-led missions include the Student Nitric Oxide Explorer (SNOE, 1998 - 2002), the Student Dust Counter (SDC) on New Horizons (2006 - present), the Colorado Student Space Weather Experiment (CSSWE), being a very successful NSF CubeSat that launched in September 2012, and the NASA Miniature X-ray Solar Spectrometer (MinXSS) CubeSat (launch will be in early 2015). Students are involved in all aspects of the design, and they experience the full scope of the mission process from concept, to fabrication and test, and mission operations. A significant part of the student involvement in the CubeSat projects is gained by using the CubeSat development as a focal point for an existing two-semester course sequence in CU's Aerospace Engineering Sciences (AES) Department: the Space Hardware Design section of Graduate Projects I & II (ASEN 5018 & ASEN 6028). The goal of these courses is to teach graduate students how to design and build systems using a requirement-based approach and fundamental systems engineering practices. The two-semester sequence takes teams of about 15 students from requirements definition and preliminary design through manufacturing, integration, and testing. In addition to the design process, students learn key professional skills such as working effectively in groups, finding solutions to open-ended problems, and actually building a system to their own set of specifications. The partnership between AES and LASP allows us to include engineering professionals in the mix, thus more effectively training science and engineering students for future roles in the civilian or commercial space industry. The mentoring process with LASP engineers helps to mitigate risk of the inexperience of the students and ensures consistent

Modern internet-based information technologies offer great possibilities to create and improve teaching methods for students. The eLearning tool NESTOR (Network for Students in Traumatology and Orthopedics) presented here was designed to complement the existing clinical teaching in orthopedics and traumatology at the Charité, University Medicine Berlin. Using a learning management system, videos, podcasts, X-ray diagnosis, virtual patients, tests and further tools for learning and study information were combined. After implementation the eLearning project was evaluated by students. The NESTOR project offers various possibilities for knowledge acquisition. Students using the program voluntarily showed a high acceptance whereby 82.4% were very satisfied with the contents offered and 95.3% supported the idea of a future use of NESTOR in teaching. The blended learning approach was positively evaluated by 93.5% of the students. The project received the eLearning seal of quality of the Charité University Medicine Berlin. Using complex eLearning tools, such as the NESTOR project represents a contemporary teaching approach in the teaching of traumatology and orthopedics and should be offered in a blended learning context as they are well accepted by students.

The New Mexico Tech NSF-funded REU Program, Interdisciplinary Science for the Environment (ISE), hosted six cohorts of students between 2005 and 2010. The program ran for eight weeks during the first cycle and nine weeks during the second cycle, bringing in an average of twelve student participants per year. Students were provided with a stipend, food allowance, travel from home to New Mexico Tech, and free campus housing. The program sponsored weekend group field trips to scientific, environmental, and cultural sites of significance in New Mexico. For the second cycle, the ISE shared some programmatic elements with the New Mexico EPSCoR Undergraduate Research Opportunities Program (UROP). The majority of the research projects focused on the geosciences, with interdepartmental participation from researchers in earth science, hydrology, chemistry, environmental science, and biology. The ISE adopted a non-traditional approach to matching student participants with research projects and faculty mentors. Students were selected from different disciplines to work together in pairs on each project. This model provided the students with a peer collaborator in addition to the guidance of their faculty mentors and support from graduate students associated with the different projects. The focus on cohort, both within the individual research projects and each year's group, enabled and enhanced the students' critical thinking, problem-solving and teamwork skills. Students would routinely seek out the advice of their peers when they hit a roadblock in their research. This collaboration also occurred across the boundaries of the ISE and UROP cohorts. Long-term follow up has shown that a significant number of the student participants have continued on to graduate school. Students credit the program with developing their capacity to work on complex problems in an interdisciplinary group environment. Additionally, many students have continued contact with their research partners

A unified academic model based on the project-based learning (PBL) methodology was implemented, in the 2012-2013 period, in the School of Engineering at Universidad Europea de Madrid. The purpose of this paper is to explore whether teachers and students participating in the capstone projects feel that the objectives for which this methodology was designed for are being achieved. The data were collected through interviews to participants at the end of the PBL experience. The results are encouraging, as students seem to be more motivated, and they say that they are experiencing deeper learning, and have developed key competitive skills required for their professional lives. Findings also suggest that teachers face positively the PBL as a learning approach since they perceive that students obtain a deeper learning, develop transversal skills with the projects and are more engaged with their studies. Implications and recommendations for the future of the model are also discussed.

Tomasek, Terry Morton

The purpose of this study was to examine and describe the ways various stakeholders (CBW project developer/coordinator, elementary and middle school teachers, and 5th through 8th grade students) envisioned, implemented and engaged in the citizen science project, eBird/Classroom BirdWatch. A multiple case study mixed-methods research design was used to examine student engagement in the cognitive processes associated with scientific inquiry as part of citizen science participation. Student engagement was described based on a sense of autonomy, competence, relatedness and intrinsic motivation. A goal of this study was to expand the taxonomy of differences between authentic scientific inquiry and simple inquiry to include those inquiry tasks associated with participation in citizen science by describing how students engaged in this type of science. This research study built upon the existing framework of cognitive processes associated with scientific inquiry described by Chinn and Malhotra (2002). This research provides a systematic analysis of the scientific processes and related reasoning tasks associated with the citizen science project eBird and the corresponding curriculum Classroom BirdWatch . Data consisted of responses to surveys, focus group interviews, document analysis and individual interviews. I suggest that citizen science could be an additional form of classroom-based science inquiry that can promote more authentic features of scientific inquiry and engage students in meaningful ways.

Full Text Available Assignments prepared in pair-work have long been evaluated to be more successful whencompared to individually prepared assignments in many respects in foreign language learningcontexts. However, there is not much research conducted to reveal the advantages of pair-work in preparing assignments and the linguistic characteristics of the finished texts. In this paper, depending upon an experimental study with the first year students in Department of EnglishLanguage Teaching at Hacettepe University, quality of pair-work assignments and the factors affecting the preparation process are discussed and compared to individual assignments. Results indicate a variety of advantages of student collaboration in preparing written work since outputsare far more grammatical, include less spelling mistakes, and indicate a higher level ofgrammatical awareness. Additionally, pair-work helps students build positive interpersonalrelationships and create a high level of academic solidarity and confidence.

The Association of American Medical Colleges' (AAMC) initiative for Core Entrustable Professional Activities for Entering Residency includes as an element of Entrustable Professional Activity 13 to "identify system failures and contribute to a culture of safety and improvement." We set out to determine the feasibility of using medical students' action learning projects (ALPs) to expedite implementation of evidence-based pathways for three common patient diagnoses in the emergency department (ED) setting (Atrial fibrillation, congestive heart failure, and pulmonary embolism). These prospective quality improvement (QI) initiatives were performed over six months in three Northeastern PA hospitals. Emergency physician mentors were recruited to facilitate a QI experience for third-year medical students for each project. Six students were assigned to each mentor and given class time and network infrastructure support (information technology, consultant experts in lean management) to work on their projects. Students had access to background network data that revealed potential for improvement in disposition (home) for patients. Under the leadership of their mentors, students accomplished standard QI processes such as performing the background literature search and assessing key stakeholders' positions that were involved in the respective patient's care. Students effectively developed flow diagrams, computer aids for clinicians and educational programs, and participated in recruiting champions for the new practice standard. They met with other departmental clinicians to determine barriers to implementation and used this feedback to help set specific parameters to make clinicians more comfortable with the changes in practice that were recommended. All three clinical practice guidelines were initiated at consummation of the students' projects. After implementation, 86% (38/44) of queried ED providers felt comfortable with medical students being a part of future ED QI

An emission inventory (EI) is a conventional tool to quantify and monitor anthropogenic emissions of greenhouse gases and air pollutants into the atmosphere. Gridded EI can visually show geographical patterns of emissions and their changes over time. These patterns, when available, are often determined using location data collected by regional governments, industries, and researchers. Datasets such as Carbon Monitoring and Action (CARMA, www.carma.org) are particularly useful for mapping emissions from large point sources and have been widely used in the EI community. The EI community is aware of potentially significant errors in the geographical locations of point sources, including power plants. The big challenge, however, is to review tens of thousands of power plant locations around the world and correct them where needed. The Power Plant Mapping Student Project (PPMSP) is a platform designed for students in 4th through 12th grade to improve the geographical location of power plants indicated in existing datasets to benefit international EI research. In PPMSP, we use VENTUS, a web-based platform (http://ventus.project.asu.edu/) that invites citizens to contribute power plant location data. Using VENTUS, students view scenes in the vicinity of reported power plant coordinates on Google Maps. Students either verify the location of a power plant or search for it within a designated radius using various indicators, an e-guide, and a power plant photo gallery for assistance. If the power plant cannot be found, students mark the plant as unverified. To assure quality for research use, the project contains multiple checkpoints and levels of review. While participating in meaningful research that directly benefits the EI research community, students are engaged in relevant science curricula designed to meet each grade level's Next Generation Science Standards. Students study energy, climate change, the atmosphere, and geographical information systems. The curricula is

Full Text Available Blackboard (TM provides social work educators integrated online communication tools that they can employ to facilitate student learning through features such as e-mail, discussion forums, file exchange, virtual classroom, and links to online resources. This study describes students’ experiences using Blackboard (TM to support a group project assignment. The majority of students found it easy to use and useful for the project, and indicated that they would like to use it in other courses. In addition, students gained technical skills as a result of the group project. Students’ group project grades and final course grades were comparable to those in other sections of the same course taught by this investigator. The findings of this study suggest that online technology can be used to facilitate group assignments for MSW students. The benefits include increased efficiency of group functioning and increased accountability of group members. The challenges include technical problems and student resistance to using the technology.

The APEX and PAX projects have as their overarching goal the laboratory creation and confinement of the world's first positron-electron pair plasma. Plasmas of this type have been the subject of hundreds of theoretical investigations and are also believed to play a role in various astrophysical environments. In order to achieve this goal in an experimentally accessible volume (e.g., 10 liters), a record number (≥ 10{sup 10}) of cold (∝ 1 eV) positrons are to be accumulated and combined with a corresponding population of electrons. Notable requirements include a high-intensity positron beam (such as NEPOMUC), a suitable magnetic confinement device for the pair plasma (such as a levitated dipole), high-efficiency tools for bridging the two (i.e., means by which the positrons can be efficiently cooled, trapped, and injected across flux surfaces), and diagnostics not only for the pair plasma, but also for the positron beam and for intermediary non-neutral plasmas. This talk will summarize the project as a whole and recent work by the APEX/PAX team on its various elements.

Craine, Erin M.; DeBenedetti, Jennifer C.

2012-05-01

There is a growing movement in the educational field to promote science, technology, engineering and math studies, stemming from a concern about waning understanding and interest among K-12 students in these topics. STEM Laboratory, Inc. (STEM) has developed a Sky Brightness Meter (SBM) that can be used with ease yet produces complex information relating to light at night monitoring. STEM sees the SBM and its corresponding data archive as a means to involve students in projects that relate to scientific method exploration, makes science more accessible, and encourages a life long appreciation and understanding of scientific endeavors. In this paper we present an example of a project template that could be used by students studying effects of artificial light on sky brightness. STEM has developed several outreach lessons aligned with the National Common Core Curriculum, Systems Thinking concepts and local standards to be implemented in classrooms or independent youth organizations.

Overdensity of galaxies in the environment of quasar pairs

Sandrinelli, A.; Falomo, R.; Treves, A.; Scarpa, R.; Uslenghi, M.

2018-03-01

We report on a study of the galaxy environments of low redshift physical quasars pairs. We selected 20 pairs having projected separation Survey images, we evaluated the galaxy overdensity around these quasars in pairs and then compare it with that of a sample of isolated quasars with same redshift and luminosity. It is found that on average there is a systematic larger overdensity of galaxies around quasars in pairs with respect to that of isolated quasars. This may represent a significant link between nuclear activity and galaxy environment. However, at odds with that, the closest quasar pairs seem to inhabit poorer environments. Implications of present results and perspectives for future work are briefly discussed.

Pairing gaps from nuclear mean-field models

Bender, M.; Rutz, K.; Maruhn, J.A.

2000-01-01

We discuss the pairing gap, a measure for nuclear pairing correlations, in chains of spherical, semi-magic nuclei in the framework of self-consistent nuclear mean-field models. The equations for the conventional BCS model and the approximate projection-before-variation Lipkin-Nogami method are formulated in terms of local density functionals for the effective interaction. We calculate the Lipkin-Nogami corrections of both the mean-field energy and the pairing energy. Various definitions of the pairing gap are discussed as three-point, four-point and five-point mass-difference formulae, averaged matrix elements of the pairing potential, and single-quasiparticle energies. Experimental values for the pairing gap are compared with calculations employing both a delta pairing force and a density-dependent delta interaction in the BCS and Lipkin-Nogami model. Odd-mass nuclei are calculated in the spherical blocking approximation which neglects part of the the core polarization in the odd nucleus. We find that the five-point mass difference formula gives a very robust description of the odd-even staggering, other approximations for the gap may differ from that up to 30% for certain nuclei.

Group work has many benefits for a student's professional development but it is difficult to determine the individual contributions to the group assessment tasks. Peer assessment of an individual's contribution to group work can be used to encourage student participation. It is important that the method of peer assessment is fair and that the students' submissions be treated confidentially. A model for peer assessment of individual contributions to the group assessment is described. Students who did not participate adequately in the group were penalised resulting in a reduced individual grade. Perceptions of the peer assessment method are reported for students enrolled (n = 169) in the subject 'Medical Radiations Project'. The questionnaire showed a positive student response towards the peer assessment model.

Particle-number conservation in odd mass proton-rich nuclei in the isovector pairing case

International Nuclear Information System (INIS)

Fellah, M.; Allal, N.H.; Oudih, M.R.

2015-01-01

An expression of a wave function which describes odd–even systems in the isovector pairing case is proposed within the BCS approach. It is shown that it correctly generalizes the one used in the pairing between like-particles case. It is then projected on the good proton and neutron numbers using the Sharp-BCS (SBCS) method. The expressions of the expectation values of the particle-number operator and its square, as well as the energy, are deduced in both approaches. The formalism is applied to study the isovector pairing effect and the number projection one on the ground state energy of odd mass N ≈ Z nuclei using the single-particle energies of a deformed Woods–Saxon mean-field. It is shown that both effects on energy do not exceed 2%, however, the absolute deviations may reach several MeV. Moreover, the np pairing effect rapidly diminishes as a function of (N - Z). The deformation effect is also studied. It is shown that the np pairing effect, either before or after the projection, as well as the projection effect, when including or not the isovector pairing, depends upon the deformation. However, it seems that the predicted ground state deformation will remain the same in the four approaches. (author)

High School Students' Reasons for Their Science Dispositions: Community-Based Innovative Technology-Embedded Environmental Research Projects

Science.gov (United States)

Ebenezer, Jazlin; Kaya, Osman Nafiz; Kasab, Dimma

2018-05-01

The purpose of this investigation was to qualitatively describe high school students' reasons for their science dispositions (attitude, perception, and self-confidence) based on their long-term experience with innovative technology-embedded environmental research projects. Students in small groups conducted research projects in and out of school with the help of their teachers and community experts (scientists and engineers). During the 3-year period of this nationally funded project, a total of 135 students from five schools in a mid-west State participated in research activities. Of the 135 students, 53 students were individually interviewed to explore reasons for their science dispositions. Students' reasons for each disposition were grouped into categories, and corresponding frequency was converted to a percentage. The categories of reasons were not only attributed to the use of innovative technologies in environmental research but also the contexts and events that surrounded it. The reasons that influenced students' science dispositions positively were because engaging in environmental research projects with technology contributed to easing fear and difficulty, building a research team, disseminating findings, communicating with the community, researching with scientists, training by teachers, and acknowledging teachers' knowledge. These results advanced how and why students develop science dispositions in the positive direction, which are as follows: building science teacher capacity, developing a community of inquirers, and committing to improve pedagogical practices.

The School of Engineering at Universidad Europea de Madrid (UEM) implemented, starting in the 2012-2013 period, a unified academic model based on project-based learning as the methodology used throughout the entire School. This model expects that every year, in each grade, all the students should participate in a capstone project integrating the contents and competencies of several courses. This paper presents the academic context under which this experience has been implemented, and a summary of the work done to design and implement the Project-Based Engineering School at the UEM. The steps followed, the structure used, some sample projects, as well as the difficulties and benefits of implementing the programme are discussed in this paper. The results are encouraging as students are more motivated and the initial set objectives were accomplished.

This project-based learning combined the chemistry of separation process using steam distillation with engineering design process in an undergraduate chemistry course. Students built upon their knowledge of phase changes, immiscible mixture, and the relationship between vapor pressure and boiling point to complete a project of modifications steam distillation apparatus. The research method is a qualitative case study, which aims to describe how (1) the creative thinking skills of students emerged during six weeks of theproject, (2) students built steam distillation apparatus characteristics as the project product and (3) students response to the project-based learning model. The results showed that the students had successfully constructed a steam distillation apparatus using plastic kettle as steam generator and distillation flask. A Plastic tubewas used to drain water vapor from steam generator to distillation flask and to drain steam containing essential oil to the condenser. A biscuit tin filled with ice was used as a condenser. The time required until resulting distillate was fifteen minutes. The production of essential was conductive qualitatively by a very strong smell typical of essential oil and two phases of distillate. Throughout the project, students formulated the relevant and varied problem, formulated the goals, proposed the ideas of the apparatus and materials, draw apparatus design, constructed apparatus, tested apparatus, evaluated, and reported the project. Student response was generally positive. They were pleased, interested, more understanding the concepts and work apparatus principles, also implemented new ideas. These results indicate that project-based learning can develop students' creative thinking skills. Based on these results, it is necessary to conduct research and implemented project-based learning to other concepts.

Beach, Dale L; Alvarez, Consuelo J

2015-12-01

Synthetic biology offers an ideal opportunity to promote undergraduate laboratory courses with research-style projects, immersing students in an inquiry-based program that enhances the experience of the scientific process. We designed a semester-long, project-based laboratory curriculum using synthetic biology principles to develop a novel sensory device. Students develop subject matter knowledge of molecular genetics and practical skills relevant to molecular biology, recombinant DNA techniques, and information literacy. During the spring semesters of 2014 and 2015, the Synthetic Biology Laboratory Project was delivered to sophomore genetics courses. Using a cloning strategy based on standardized BioBrick genetic "parts," students construct a "reporter plasmid" expressing a reporter gene (GFP) controlled by a hybrid promoter regulated by the lac-repressor protein (lacI). In combination with a "sensor plasmid," the production of the reporter phenotype is inhibited in the presence of a target environmental agent, arabinose. When arabinose is absent, constitutive GFP expression makes cells glow green. But the presence of arabinose activates a second promoter (pBAD) to produce a lac-repressor protein that will inhibit GFP production. Student learning was assessed relative to five learning objectives, using a student survey administered at the beginning (pre-survey) and end (post-survey) of the course, and an additional 15 open-ended questions from five graded Progress Report assignments collected throughout the course. Students demonstrated significant learning gains (p Biology Laboratory Project enhanced their understanding of molecular genetics. The laboratory project is highly adaptable for both introductory and advanced courses.

Investigating Changes in Student Attitudes and Understanding of Science through Participation in Citizen Science Projects in College Coursework

Cardamone, Carolin; Cobb, Bethany E.

2018-01-01

Over the last decade, web-based “citizen science” projects such as the Zooniverse have allowed volunteers and professional scientists to work together for the advancement of science. While much attention has been paid to the benefits to science from these new projects, less attention has been paid to their impact on the participants and, in particular, to the projects’ potential to impact students who might engage in these projects through coursework. We report on a study engaging students in introductory astronomy classes at the George Washington University and Wheelock College in an assignment in which each student individually contributed to a “physics” or “space” citizen science project of their choice, and groups of students worked together to understand and articulate the scientific purpose of a citizen science project to which they all contributed. Over the course of approximately four weeks, the students kept logs of their individual contributions to the project, and recorded a brief reflection on each of their visits (noting, for example, interesting or confusing things they might encounter along the way). The project culminated with each group delivering a creative presentation that demonstrated their understanding of both the science goals of the project and the value of their own contributions to the project. In this talk, we report on the experience of the students with the project and on an assessment of the students’ attitudes toward science and knowledge of the process of science completed before the introduction of the assignment and again at its conclusion.

2017-12-01

Project-based learning (PBL) is motivational for students to learn research methodology skills. It is a way to engage and give them ownership over their own learning. The aim of this study is to use PBL for application of research methodology skills for better learning by encouraging an all-inclusive approach in teaching and learning rather than an individualized tailored approach. The present study was carried out for MBBS 6 th - and 7 th -semester students of community medicine. Students and faculties were sensitized about PBL and components of research methodology skills. They worked in small groups. The students were asked to fill the student feedback Questionnaire and the faculty was also asked to fill the faculty feedback Questionnaire. Both the Questionnaires were assessed on a 5 point Likert scale. After submitted projects, document analysis was done. A total of 99 students of the 6 th and 7 th semester were participated in PBL. About 90.91% students agreed that there should be continuation of PBL in subsequent batches. 73.74% felt satisfied and motivated with PBL, whereas 76.77% felt that they would be able to use research methodology in the near future. PBL requires considerable knowledge, effort, persistence, and self-regulation on the part of the students. They need to devise plans, gather information evaluate both the findings, and their approach. Facilitator plays a critical role in helping students in the process by shaping opportunity for learning, guiding students, thinking, and helping them construct new understanding.

Service learning is endorsed by the Liaison Committee on Medical Education (LCME) as an integral part of U.S. medical school curricula for future physicians. Service learning has been shown to help physicians in training rediscover the altruistic reasons for pursuing medicine and has the potential to enhance students' perspectives of humanism in medicine. The Kalaupapa service learning project is a unique collaboration between disadvantaged post-baccalaureate students with an underserved rural community. This study was conducted to determine whether the Kalaupapa service learning curricula enhanced student perspectives of humanism in medicine at an early stage of their medical training. Program participants between 2008 and 2014 (n = 41) completed written reflections following the conclusion of the service learning project. Four prompts guided student responses. Reflections were thematically analyzed. Once all essays were read, team members compared their findings to condense or expand themes and assess levels of agreement. Emerging themes of resilience and unity were prominent throughout the student reflections. Students expressed respect and empathy for the patients' struggles and strengths, as well as those of their peers. The experience also reinforced students' commitment to service, particularly to populations in rural and underserved communities. Students also gained a deeper understanding of the patient experience and also of themselves as future physicians. To identify and address underserved and rural patients' health care needs, training programs must prepare an altruistic health care workforce that embraces the humanistic element of medicine. The Kalaupapa service learning project is a potential curricular model that can be used to enhance students' awareness and perspectives of humanism in medicine.

Using Multiple Methods to teach ASTR 101 students the Path of the Sun and Shadows

Science.gov (United States)

D'Cruz, Noella L.

2015-01-01

It seems surprising that non-science major introductory astronomy students find the daily path of the Sun and shadows created by the Sun challenging to learn even though both can be easily observed (provided students do not look directly at the Sun). In order for our students to master the relevant concepts, we have usually used lecture, a lecture tutorial (from Prather, et al.) followed by think-pair-share questions, a planetarium presentation and an animation from the Nebraska Astronomy Applet Project to teach these topics. We cover these topics in a lecture-only, one semester introductory astronomy course at Joliet Junior College. Feedback from our Spring 2014 students indicated that the planetarium presentation was the most helpful in learning the path of the Sun while none of the four teaching methods was helpful when learning about shadows cast by the Sun. Our students did not find the lecture tutorial to be much help even though such tutorials have been proven to promote deep conceptual change. In Fall 2014, we continued to use these four methods, but we modified how we teach both topics so our students could gain more from the tutorial. We hoped our modifications would cause students to have a better overall grasp of the concepts. After our regular lecture, we gave a shorter than usual planetarium presentation on the path of the Sun and we asked students to work through a shadow activity from Project Astro materials. Then students completed the lecture tutorial and some think-pair-share questions. After this, we asked students to predict the Sun's path on certain days of the year and we used the planetarium projector to show them how well their predictions matched up. We ended our coverage of these topics by asking students a few more think-pair-share questions. In our poster, we will present our approach to teaching these topics in Fall 2014, how our Fall 2014 students feel about our teaching strategies and how they fared on related test questions.

Some advances in pairing theory

International Nuclear Information System (INIS)

Rowe, D.J.

2001-01-01

Two advances are reviewed in the application of pairing-force theory in the nuclear shell model. The first exploits a discovery that a wide range of two-nucleon interactions conserve seniority as a good quantum number. As a consequence, the eigenstates of a Hamiltonian with such an interaction belong to irreducible representations of a compact unitary-symplectic group. This makes it possible to extend the simply-solvable models with J=0 pairing forces to a much richer set of models and still obtain states uniquely classified by their seniority and angular momentum quantum numbers. Moreover, many of the low-lying energy levels of such models can be obtained algebraically; in technical terms, the models are in some cases completely solvable and in other cases partially solvable by algebraic methods. The second advance exploits the discovery that, in a coherent state representation, states of good nucleon number can be projected analytically from BCS vacuum and excited quasiparticle states. This makes it possible to perform calculations in a number-projected BCS basis without losing much of the advantage of working of the quasiparticle scheme. (Author)

2016-03-16

Increasingly, medical educators are incorporating reflective writing and original creative work into educational practices with the goals of stimulating student self-awareness, appreciation of multiple perspectives, and comfort with ambiguity and uncertainty. This study investigated students' creative projects to assess the extent to which they adopted a patient/relationship-centered, emotionally connected position toward patients and families. Over a 10 year period, students on a required third year pediatrics clerkship individually or in groups completed either a reflection or an education project using a creative medium. 520 projects (representing 595 students, 74.7 % of total eligible students) were qualitatively analyzed according to various thematic and emotion-based dimensions. The majority of projects were personal narrative essays and poetry. The largest number of project themes related to the importance of patient/relationship-centered medicine with patients. The next largest number of projects focused on health education of parents, patients, or classmates. In telling their stories, students were more likely to use a personal voice representing either their or the patient's perspective than an objective, impersonal one. In terms of emotional tone, projects were more likely to be serious than humorous. The largest number of students' emotions expressed an empathic tone. Students identified a large number and wide range of both negative and positive feelings in themselves and their patients. The majority of student emotions were positive, while the majority of patient and family emotions were negative. Students' preference for patient-centered, relational themes, as well as their tendency to favor the first voice, empathic tone, and willingness to express a range of positive and negative emotions in presenting their projects, suggests that they valued emotional connection with patients and families during the pediatrics clerkship experience.

Full Text Available This paper explores student perceptions of the effects of pairing discipline-specific language instruction with the traditional method of course delivery in economics. Our research involved teaching content-based English as an additional language (EAL tutorials to a small group of ten international students taking first-year introductory economics courses. These voluntary participants completed pre- and post-treatment assessments with exit interviews at the end of the project. Assessment results and interviews suggest that students perceive that discipline-specific language instruction such as our EAL tutorials assists in the development of increased content and language proficiency. They also believe that vocabulary development is one of the most critical activities to support these goals; reading skills are also important but require more time and commitment than students can afford to give. Despite the students’ interest in the project, their heavy class schedules prevented many from participating; our group was limited to ten students which precludes any assurance of statistical significance. In spite of the limitations, we believe that the project can still contribute valuable qualitative lessons to the literature of content-based language instruction in which the discipline of economics has not been well represented.

Misher, Pamela Henry

This case study explored the utilization of project-based learning (PBL) and how it affected student engagement and interest in STEM careers. Sixty-seven students and nine teachers participated in this case study. Three research questions addressed student engagement, perceptions, and challenges during PBL implementation. This study was designed to understand the experiences teachers and students had when they participated in a PBL environment. This research investigated how to develop a globally skilled workforce utilizing a PBL approach and the challenges teachers encountered during implementation. The survey data and informal focus-group sessions with staff and students were utilized, analyzed, and summarized in order to obtain insight on perceptions, challenges, and implementation of PBL. PBL is an instructional approach that was designed to encourage more engaged learning. This approach was built upon realistic learning activities that stimulated student interest and motivation. This research discovered that PBL did teach content and 21st century skills as students worked collaboratively toward a common goal while responding to a question or problem. This study revealed that rigorous projects were carefully planned to aid students in learning important academic content. This study displayed how PBL allowed students to reflect on their projects and ideas with the opportunity to voice their decisions and findings. This instructional approach provided opportunities for students to investigate and strengthen interest in future STEM careers. The driving force of America's future economy and maintaining the competitive edge will be through more innovation, mainly derived from advances in STEM (Science, Technology, Engineering, and Math) careers. As business and industry leaders stressed the importance of improving STEM education, there continued to be a need to better prepare students to fill STEM-related careers. This research adds to the current body of research

Ker, Andrew D.

2004-06-01

We give initial results from a new project which performs statistically accurate evaluation of the reliability of image steganalysis algorithms. The focus here is on the Pairs and RS methods, for detection of simple LSB steganography in grayscale bitmaps, due to Fridrich et al. Using libraries totalling around 30,000 images we have measured the performance of these methods and suggest changes which lead to significant improvements. Particular results from the project presented here include notes on the distribution of the RS statistic, the relative merits of different "masks" used in the RS algorithm, the effect on reliability when previously compressed cover images are used, and the effect of repeating steganalysis on the transposed image. We also discuss improvements to the Pairs algorithm, restricting it to spatially close pairs of pixels, which leads to a substantial performance improvement, even to the extent of surpassing the RS statistic which was previously thought superior for grayscale images. We also describe some of the questions for a general methodology of evaluation of steganalysis, and potential pitfalls caused by the differences between uncompressed, compressed, and resampled cover images.

Basic medical sciences and clinical teachings are not coordinated in the present medical education system. They are not taught keeping in mind the outcomes required at the time of actual handling of patients in the community. An educational development project was implemented in the Department of Pathology with the aim that it will result in the student learning to link the pathophysiology of the disease to clinical scenarios and become fully competent for lifelong medical practice. The pathology teaching of the second professional batch was modified by starting with defining the desired outcomes/competencies in the student's knowledge, skills, and attitude which were then addressed by lectures, demonstrations, practical classes and small group activities where case scenarios and laboratory reports were included. The outcome was assessed by Objectively Structured Clinical/Practical Examination and multiple choice questions. Force field analysis, faculty and student interviews, and questionnaires were used to assess the factors affecting its implementation and impact. Totally 80 students of the 2(nd) Professional MBBS were exposed to a competency-based education development project. It was found that the system was appreciated by faculty and students, especially the integration with clinical scenarios. There were many factors which influenced the execution of this program, including motivation level of students and faculty, time, logistics and meticulous planning. There was a significant improvement in student's performance and satisfaction. Many factors including prior planning were a major determinant for the success of this education development project.

With recent technological advances, the barriers to filmmaking have been lowered, and it is now possible to record and edit video footage with a smartphone or a handheld camera and free software. Students accustomed to documenting their every-day experiences for multimedia-rich social networking sites feel excited and creatively inspired when asked to take on ownership of more complex video projects. With a small amount of guidance on shooting primary and secondary footage and an overview of basic interview skills, students are self-motivated to identify the learning themes with which they resonate most strongly and record their footage in a way that is true to their own experience. The South Central Climate Science Center (SC-CSC) is one of eight regional centers formed by the U.S. Department of the Interior in order to provide decision makers with the science, tools, and information they need to address the impacts of climate variability and change on their areas of responsibility. An important component of this mission is to innovate in the areas of translational science and science communication. This presentation will highlight how the SC-CSC used student-driven video projects to document our Early Career Researcher Workshop and our Undergraduate Internship for Underrepresented Minorities. These projects equipped the students with critical thinking and project management skills, while also providing a finished product that the SC-CSC can use for future outreach purposes.

Wilhelm, Jennifer Anne

This case study examined what student content understanding could occur in an inner city Industrial Electronics classroom located at Tree High School where project-based instruction, enhanced with technology, was implemented for the first time. Students participated in a project implementation unit involving sound waves and trigonometric reasoning. The unit was designed to foster common content learning (via benchmark lessons) by all students in the class, and to help students gain a deeper conceptual understanding of a sub-set of the larger content unit (via group project research). The objective goal of the implementation design unit was to have students gain conceptual understanding of sound waves, such as what actually waves in a wave, how waves interfere with one another, and what affects the speed of a wave. This design unit also intended for students to develop trigonometric reasoning associated with sinusoidal curves and superposition of sinusoidal waves. Project criteria within this design included implementation features, such as the need for the student to have a driving research question and focus, the need for benchmark lessons to help foster and scaffold content knowledge and understanding, and the need for project milestones to complete throughout the implementation unit to allow students the time for feedback and revision. The Industrial Electronics class at Tree High School consisted of nine students who met daily during double class periods giving 100 minutes of class time per day. The class teacher had been teaching for 18 years (mathematics, physics, and computer science). He had a background in engineering and experience teaching at the college level. Benchmark activities during implementation were used to scaffold fundamental ideas and terminology needed to investigate characteristics of sound and waves. Students participating in benchmark activities analyzed motion and musical waveforms using probeware, and explored wave phenomena using waves

2009-11-03

The anatomy course offers important opportunities to develop professionalism at an early stage in medical education. It is an academically significant course that also engenders stress in some students. Over a three-year period, 115 of 297 students completed creative projects. Thirty-four project completers and 47 non-completers consented to participate in the study. Projects were analyzed for professionalism themes using grounded theory. A subset of project completers and non-completers were interviewed to determine their views about the stress of anatomy and medical school, as well as the value of the creative projects. We also compared test performance of project completers and non-completers. Projects completed early in the course often expressed ambivalence about anatomy, whereas later projects showed more gratitude and sense of awe. Project completers tended to report greater stress than noncompleters, but stated that doing projects reduced stress and caused them to develop a richer appreciation for anatomy and medicine. Project completers performed significantly lower than non-completers on the first written exam (pre-project). Differences between groups on individual exams after both the first and second creative project were nonsignificant. For some students, creative projects may offer a useful way of reflecting on various aspects of professionalism while helping them to manage stress.

Undergraduate education incorporating active learning and vicarious experience through education outreach presents a critical opportunity to influence future engineering teaching and practice capabilities. Engineering education outreach activities have been shown to have multiple benefits; increasing interest and engagement with science and engineering for school children, providing teachers with expert contributions to engineering subject knowledge, and developing professional generic skills for engineers such as communication and teamwork. This pilot intervention paired 10 pre-service teachers and 11 student engineers to enact engineering outreach in primary schools, reaching 269 children. A longitudinal mixed methods design was employed to measure change in attitudes and Education Outreach Self-Efficacy in student engineers; alongside attitudes, Teaching Engineering Self-Efficacy and Engineering Subject Knowledge Confidence in pre-service teachers. Highly significant improvements were noted in the pre-service teachers' confidence and self-efficacy, while both the teachers and engineers qualitatively described benefits arising from the paired peer mentor model.

Undergraduate research exposure leads to increased recruitment into academic medicine, enhanced employability and improved postgraduate research productivity. Uptake of undergraduate research opportunities is reported to be disappointing, and little is known about how students perceive research. To investigate opportunities for undergraduate participation in research, recognition of such opportunities, and associated skills development. A mixed method approach, incorporating student focus and study groups, and documentary analysis at five UK medical schools. Undergraduates recognised the benefits of acquiring research skills, but identified practical difficulties and disadvantages of participating. Analysis of 905 projects in four main research skill areas - (1) research methods; (2) information gathering; (3) critical analysis and review; (4) data processing - indicated 52% of projects provided opportunities for students to develop one or more skills, only 13% offered development in all areas. In 17%, project descriptions provided insufficient information to determine opportunities. Supplied with information from a representative sample of projects (n = 80), there was little consensus in identifying skills among students or between students and researchers. Consensus improved dramatically following guidance on how to identify skills. Undergraduates recognise the benefits of research experience but need a realistic understanding of the research process. Opportunities for research skill development may not be obvious. Undergraduates require training to recognise the skills required for research and enhanced transparency in potential project outcomes.

Methods These prospective quality improvement (QI initiatives were performed over six months in three Northeastern PA hospitals. Emergency physician mentors were recruited to facilitate a QI experience for third-year medical students for each project. Six students were assigned to each mentor and given class time and network infrastructure support (information technology, consultant experts in lean management to work on their projects. Students had access to background network data that revealed potential for improvement in disposition (home for patients. Results Under the leadership of their mentors, students accomplished standard QI processes such as performing the background literature search and assessing key stakeholders’ positions that were involved in the respective patient’s care. Students effectively developed flow diagrams, computer aids for clinicians and educational programs, and participated in recruiting champions for the new practice standard. They met with other departmental clinicians to determine barriers to implementation and used this feedback to help set specific parameters to make clinicians more comfortable with the changes in practice that were recommended. All three clinical practice guidelines were initiated at consummation of the students’ projects. After implementation, 86% (38/44 of queried ED providers felt comfortable

On the restoration of symmetry in paired Fermion systems

International Nuclear Information System (INIS)

Flocard, H.

1997-01-01

We consider the problem of symmetry restoration as treated by the method of variation after projection (VAP) on good quantum numbers. We show that for compact groups, the convergence of the connected-linked expansion of the VAP kernels over the physically relevant interval of integration of the pairing gauge angle is not guaranteed. We propose instead a method which generates approximations of increasing precision which are periodic with respect to the gauge angle while differing from truncations of the Fourier expansion of the VAP kernels. For the projection on good particle number in paired fermion systems, this new approach is shown to be equivalent to an expansion in powers of the pairing tensor. For the lowest order approximation, an analytical integration over the gauge angle is performed explicitly. It provides the algebraic forms of the single particle Hamiltonian and of the pairing field entering generalized Hartree endash Fock endash Bogoljubov equations. Contrary to most approximations, the validity of the expressions for the energy and mean values of operators thus obtained is not a priori restricted where the fluctuation of the operator associated with the broken symmetry is large. We also derive the first-order correction to the pairing-order parameter. We test the quality of the proposed method on a non-trivial soluble model. copyright 1997 Academic Press, Inc

2016-04-01

RESEt (Research and Education Svalbard Experience www.resetsvalbard.it) is an ongoing educational project focusing mainly on polar and climate system topics. It started in 2014 and will end in 2017 with the high school diploma of the 22 students (16 y. o.) making the participant class. This class attend a school (Liceo Filzi, Rovereto, Trento. Italy) with a primary focus on disciplines like philosophy and education, rather then STEM (Science, Technology, Engineering, and Mathematics). Nevertheless their science curricula include climate topics that are rather challenging to grasp and, at the same time, crucial for their scientific citizenship. Some questions arise: How to foster their interest in geosciences topics? How to engage them in authentic scientific knowledge? How to increase their interest in scientific university courses during their post-secondary career? RESEt project will attempt to answer these questions through the development of integrated activities distributed over the last three years of their high school cycle. The most important moment will be an educational scientific expedition at the Svalbard, an archipelago located in the Arctic. The expedition be entirely organized, planned, and directed by students. In Svalbard, students will visit the main scientific facilities devoted to climate studies including those of Italian CNR (National Research Council) and they will perform some environmental measurement using data-loggers. Students are even involved in the fundraising process to raise more than ten thousand Euros needed to for travel expenses. This work is aimed mainly at presenting some of the preliminary data collected during the RESEt project, including the fundraising aspects. The management of the RESEt project strongly relies on the experience and network gained by the abstract author during the participation to the Education and Public Outreach (EPO) program of International Polar Year (IPY) 2007-2009 as well as the support of Polar

Skynet is a worldwide robotic telescope network operated by the University of North Carolina at Chapel Hill with active observing sites on 3 continents. The queue-based observation request system is simple enough to be used by middle school students, but powerful enough to supply data for research scientists. The Skynet Junior Scholars program, funded by the NSF, has teamed up with professional astronomers to engage students from middle school to undergraduates in authentic research projects, from target selection through image analysis and publication of results. Asteroid research is a particularly fruitful area for youth collaboration that reinforces STEM education standards and can allow students to make real contributions to scientific knowledge, e.g., orbit refinement through astrometric submissions to the Minor Planet Center. We have created a set of projects for youth to: 1. Image an asteroid, make a movie, and post it to a gallery; 2. Measure the asteroid’s apparent motion using the Afterglow online image processor; and 3. Image asteroids from two or more telescopes simultaneously to demonstrate parallax. The apparent motion and parallax projects allow students to estimate the distance to their asteroid, as if they were the discoverer of a brand new object in the solar system. Older students may take on advanced projects, such as analyzing uncertainties in asteroid orbital parameters; studying impact probabilities of known objects; observing time-sensitive targets such as Near Earth Asteroids; and even discovering brand new objects in the solar system.Images are acquired from among seven Skynet telescopes in North Carolina, California, Wisconsin, Canada, Australia, and Chile, as well as collaborating observatories such as WestRock in Columbus, Georgia; Stone Edge in El Verano, California; and Astronomical Research Institute in Westfield, Illinois.

Interprofessional teams provide the promise of effective, comprehensive and reliable care. Interprofessional education (IPE) promotes students' knowledge and attitudes to support interprofessional teamwork, and problem-based learning formats enable students to gain valuable teamwork experience. To design, implement, and evaluate an interprofessional problem-based learning module in a large Canadian university focusing on the effects of this format on students' knowledge, attitudes, and perceptions. A pre-post mixed-methods research design was used, with a convenience sample of 24 students from medicine, pharmacy, nursing, physical therapy, and occupational therapy. Participants in the module were divided into 5 teams composed of one member from each discipline. Pre-tests were delivered just prior to module participation and post-tests directly followed. Students also participated in focus groups to provide feedback about module content, process, outcomes, and practical considerations. Students' attitudes toward interprofessional teamwork improved from baseline to post-intervention. Mean differences were significant using paired t-tests on confidence in professional role (p <0.001), communication (p = 0.02), understanding roles of others (p = 0.002), identification with the team (p = 0.002), comfort with members (p = 0.047), cooperation with team members (p = 0.004), team perceptions (p = 0.04), decision-making (p <0.001), team efficiency (p <0.001), minimal conflict (p = 0.04), and group contributions (p = 0.03). Focus group themes indicated students were satisfied with the module, perceived increased knowledge about roles and perspectives, greater confidence to collaborate, and increased motivation to engage in intra-curricular IPE. The timing of their exposure within their respective educational programs was identified as important.

Data on private well water quality is slowly being collected and evaluated from a number of different agencies, sources and projects. A new project is designed both for training high school students and to help assess the quality of water from rural domestic wells in Nebraska. This "crowd sourced" program engaging high school agricultural education programs, FFA chapters, and science classes with students sampling and testing water sampling from rural domestic wells from 12 districts across the state. Students and teachers from selected school were trained through multiple school visits, both in the classroom and in the field. Classroom visits were used to introduce topics such as water quality and groundwater, and testing methods for specific analytes. During the field visit, students were exposed to field techniques, the importance of accuracy in data collection, and what factors might influence the water in sampled wells. High school students learn to sample and test water independently. Leadership and initiative is developed through the program, and many experience the enlightenment that comes with citizen science. A customized mobile app was developed for ease of data entry and visualization, and data uploaded to a secure website where information was stored and compared to laboratory tests of the same measurements. General water quality parameters, including pH, electrical conductivity, major anions are tested in the field and laboratory, as well as environmental contaminants such as arsenic, uranium, pesticides, bacteria. Test kits provided to each class were used by the students to measure selected parameters, and then duplicate water samples were analyzed at a university laboratory. Five high schools are involved in the project during its first year. Nitrate, bacteria and pesticides represent major

Full Text Available Abstract Background The anatomy course offers important opportunities to develop professionalism at an early stage in medical education. It is an academically significant course that also engenders stress in some students. Methods Over a three-year period, 115 of 297 students completed creative projects. Thirty-four project completers and 47 non-completers consented to participate in the study. Projects were analyzed for professionalism themes using grounded theory. A subset of project completers and non-completers were interviewed to determine their views about the stress of anatomy and medical school, as well as the value of the creative projects. We also compared test performance of project completers and non-completers. Results Projects completed early in the course often expressed ambivalence about anatomy, whereas later projects showed more gratitude and sense of awe. Project completers tended to report greater stress than noncompleters, but stated that doing projects reduced stress and caused them to develop a richer appreciation for anatomy and medicine. Project completers performed significantly lower than non-completers on the first written exam (pre-project. Differences between groups on individual exams after both the first and second creative project were nonsignificant. Conclusion For some students, creative projects may offer a useful way of reflecting on various aspects of professionalism while helping them to manage stress.

The Government White Paper Saving Lives: Our Healthier Nation (1999) provides a clear indication that accidents are a serious public health problem and have been targeted by the Department of Health as a key area for prevention over the next 10 years. School-based injury prevention programmes have been identified as one of the key settings for the implementation of the White Paper's heath promotion strategies. The Citizen Safety Project (CSP) is a peer-delivered injury prevention programme for Year 10 students (14-15 years) and Year 2 pupils (6-7 years). This paper summarizes the findings of a pilot study that assessed the feasibility of implementing the CSP in schools and of conducting a larger study. Working as part of their Personal Social Health Education lessons, 11 pairs (n = 22) of Year 10 students developed a project to take one accident prevention theme of their choice into a primary school to teach small groups of five or six Year 2 pupils (n = 55). A formative evaluation was conducted, based on interviews with Year 2 and Year 10 teachers (n = 2), and the diaries of Year 10 students. Knowledge of accident prevention and risk awareness was measured in Year 2 pupils using the Draw and Write technique, and impact on Year 10 students was measured using self-esteem and locus of control inventories. Using both statistical and thematic analysis the study concludes that the CSP is well accepted, improves knowledge in Year 2 pupils and boosts confidence in Year 10 students, while concurrently achieving key stage attainment targets. Implications of the study are discussed in terms of future research, as are recommendations with regard to modifications to the project.

Full Text Available Ultra strong electromagnetic fields can lead to spontaneous creation of single or multiple electron–positron pairs. A quantum field theoretical treatment of the pair creation process combined with numerical methods provides a description of the fermionic quantum field state, from which all observables of the multiple electron–positron pairs can be inferred. This allows to study the complex multi-particle dynamics of electron–positron pair creation in-depth, including multi-pair statistics as well as momentum distributions and spin. To illustrate the potential benefit of this approach, it is applied to the intermediate regime of pair creation between nonperturbative Schwinger pair creation and perturbative multiphoton pair creation where the creation of multi-pair states becomes nonnegligible but cascades do not yet set in. Furthermore, it is demonstrated how spin and helicity of the created electrons and positrons are affected by the polarization of the counterpropagating laser fields, which induce the creation of electron–positron pairs.

Student goal orientation in learning inquiry skills with modifiable software advisors

Science.gov (United States)

Shimoda, Todd Adrian

A computer support environment (SCI-WISE) for learning and doing inquiry was designed. The system incorporates software advisors that give task completion advice (eg., forming hypotheses), general purpose advice (e.g., brainstorming), or system modification advice. Advisors' knowledge includes concepts, strategies, examples, referrals to other advisors, and criteria for evaluating good products and skills. Students using SCI-WISE can select the advisors' advice type (specific, general, or hints), and when advisors give advice (anytime, alert, or ask). Students can also modify the advisors' knowledge. The system is designed partly on a theoretical framework that assumes giving students higher levels of agency will facilitate higher-level goal orientation (such as knowledge-building) and produce higher levels of competence. In two studies of sixth graders, science students took a pretest of an open-ended inquiry question and a questionnaire that measured their goal orientations. The students worked in pairs on an inquiry project about memory, using one of two versions of SCI-WISE, one modifiable and one not modifiable. After finishing the project, the students took a posttest similar to the pretest, and evaluated the system. The main hypotheses predicted that knowledge-oriented students using the modifiable version would rate the system higher, use it more effectively, and do better on the inquiry posttest than task-oriented students. The results supported many of the hypotheses generated from the theoretical framework. Knowledge-oriented students tended to rate SCI-WISE higher, use more general purpose and system development advisors, and select more general advice and hints than task-oriented students. On the posttest inquiry test, students with higher goal orientations scored higher on average, particularly when paired with another knowledge oriented student. The studies also showed that goal orientation was not correlated with grade point average. Finally, the

Bernard, Warren

2005-11-01

Authentic research projects are one type of inquiry activity as defined by the American Association for the Advancement of Science (1993) and are a core component in science education reform movements. The purpose of this study was to examine high school students' perspectives of an authentic research project. The context for this study was a local Science and Engineering Fair (SEF) that involved students from a Metro-Atlanta public high school. This study provided information about this type of activity from the student's perspective, an emic viewpoint. In this qualitative study, demographic information was used for the purposeful selection of fourteen students making up the study sample. In this descriptive ethnography, data were collected via an open-ended survey, three individual interviews, a web log, and a group interview. Interviews were audio taped and conducted according to the protocol established by Lincoln and Guba (1998). Transcripts of the interviews, web logs, and survey responses were coded and analyzed by the constant comparative method as described by Glaser and Strauss (1965). Reliability and validity were achieved through member checks and triangulation. Using Gowin's Vee diagram (1981) as a theoretical framework for analysis, themes emerged describing the students' research experience. The themes included the students' initial reactions, difficulty getting started, accepting ownership of their project, growing interest, acknowledged benefits of the research experience, and a reflective look back at their experience. Overall, students described the authentic research experience as a worthwhile activity. The implications of the study are two-fold. At the practitioner level, teachers should engage students in research, but should do so in a manner that maximizes authenticity. Examples may include having students present a formal prospectus and work with a scientist mentor. For Science Educators in teacher preparation programs, there should be an

We have identified 105 galaxy pairs at z ∼ 0.04 with the MaNGA integral-field spectroscopic data. The pairs have projected separations between 1 and 30 kpc, and are selected to have radial velocity offsets less than 600 km s‑1 and stellar mass ratio between 0.1 and 1. The pair fraction increases with both the physical size of the integral-field unit and the stellar mass, consistent with theoretical expectations. We provide the best-fit analytical function of the pair fraction and find that ∼3% of M* galaxies are in close pairs. For both isolated galaxies and paired galaxies, active galactic nuclei (AGNs) are selected using emission-line ratios and Hα equivalent widths measured inside apertures at a fixed physical size. We find AGNs in ∼24% of the paired galaxies and binary AGNs in ∼13% of the pairs. To account for the selection biases in both the pair sample and the MaNGA sample, we compare the AGN comoving volume densities with those expected from the mass- and redshift-dependent AGN fractions. We find a strong (∼5×) excess of binary AGNs over random pairing and a mild (∼20%) deficit of single AGNs. The binary AGN excess increases from ∼2× to ∼6× as the projected separation decreases from 10–30 to 1–10 kpc. Our results indicate that the pairing of galaxies preserves the AGN duty cycle in individual galaxies but increases the population of binary AGNs through correlated activities. We suggest tidally induced galactic-scale shocks and AGN cross-ionization as two plausible channels to produce low-luminosity narrow-line-selected binary AGNs.

Students in an interdisciplinary undergraduate introductory course were required to complete a group video project focused on nutrition and healthy eating. A mixed-methods approach to data collection involved observing and rating video footage of group work sessions and individual and focus group interviews. These data were analyzed and used to evaluate the effectiveness of the assignment in light of two student learning outcomes and two student development outcomes at the University of Minnesota. Positive results support the continued inclusion of the project within the course, and recommend the assignment to other programs as a viable means of promoting both content learning and affective behavioral objectives.

To describe pairing correlations in a fissioning system one commonly projects the BCS wave function separately onto good particle numbers in each fragment in the exit channel, but only onto the total number of particles in the parent system. We propose to interpolate between these limiting situations by the generator-coordinate method with the particle-number difference between the nascent fragments as the generator coordinate. Model calculations are presented for the Hill-Wheeler-box potential with a δ-function diaphragm to mimic scission

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

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

STEM Learning focusses on development of STEM-literate society, the research about implementation of STEM learning to develope students’ STEM literacy is still limited. This study is aimed to examine the effect of implementation STEM learning through the project of designing boat model on students STEM literacy in energy topic. The method of this study was a quasi-experiment with non-randomized pretest-posttest control group design. There were two classes involved, the experiment class used Project Based Learning with STEM approach and control class used Project-Based Learning without STEM approach. A STEM Literacy test instrument was developed to measure students STEM literacy which consists of science literacy, mathematics literacy, and technology-engineering literacy. The analysis showed that there were significant differences on improvement science literacy, mathematics technology-engineering between experiment class and control class with effect size more than 0.8 (large effect). The difference of improvement of STEM literacy between experiment class and control class is caused by the existence of design engineering activity which required students to apply the knowledge from every field of STEM. The challenge that was faced in STEM learning through design engineering activity was how to give the students practice to integrate STEM field in solving the problems. In additional, most of the students gave positive response toward implementation of STEM learning through design boat model project.

It is an experimental research. The population of this research is all XI-grade students of IPS SMAN 11 Padang, who were registered in the year 2013-2014. Two samples were selected by using the technique of Purposive Sampling method. The data of this research is primary data, and the data analyses are descriptive and inductive, conducted through t-test by first making tests of normality and homogeneity of both sample variants. Based on the data analyses, it is obtained that the learning points for the experimental class 1 is 76.80 and the experimental class 2 is 65.64 on the average, meaning that Sig 0.018 is smaller than α = 0.05. From the hypothesis tests, tcalc.is 2.444 and ttable is 1.67, so that H0 is rejected, meaning that there is the difference between TPS and STAD. From the results, it is expected that this could provide a solution for the problem of lowering learning points especially in economics subject. Finally, for improving the learning points of economical students, it is suggested for teachers to consider the learning models from Think Pair Share TPS and STAD.

Koparan, Timur; Güven, Bülent

2015-07-01

The point of this study is to define the effect of project-based learning approach on 8th Grade secondary-school students' statistical literacy levels for data representation. To achieve this goal, a test which consists of 12 open-ended questions in accordance with the views of experts was developed. Seventy 8th grade secondary-school students, 35 in the experimental group and 35 in the control group, took this test twice, one before the application and one after the application. All the raw scores were turned into linear points by using the Winsteps 3.72 modelling program that makes the Rasch analysis and t-tests, and an ANCOVA analysis was carried out with the linear points. Depending on the findings, it was concluded that the project-based learning approach increases students' level of statistical literacy for data representation. Students' levels of statistical literacy before and after the application were shown through the obtained person-item maps.

2009-12-01

Full Text Available A content-driven biology course for preservice, K-8 teachers has been developed. This course uses the constructivist approach, where instructors engage students by organizing information around concept-based problems. To this end a semester-long inquiry-based project was introduced where students studied lichen populations on trees located on their campus to monitor air quality. Data were incorporated into a geographical information systems (GIS database to demonstrate how it can be used to map communities. Student teams counted the number of each lichen type within a grid placed on each tree trunk sampled and entered this information into a GIS database. The students constructed maps of lichen populations at each sample site and wrote abstracts about their research. Student performance was assessed by preparation of these abstracts as well as scores on pre- and posttests of key content measures. Students also completed a survey to determine whether the project aided in their comprehension as well as their interest in incorporating this activity into their own curricula. The students’ pre- and posttest results showed an eightfold improvement in the total score after the semester project. Additionally, correct responses to each individual content measure increased by at least 35%. Total scores for the abstract ranged from 12 to 20 points out of 20 total points possible (60% to 100% with a mean score of 15.8 points (78%. These results indicate that this exercise provided an excellent vehicle to teach students about lichens and their use as bioindicators and the application of geospatial technologies to map environmental data.

Nuclear pairing reduction due to rotation and blocking

International Nuclear Information System (INIS)

Wu Xi; Zhang Zhenhua; Lei Yi'an; Zeng Jinyan

2010-01-01

Nuclear pairing gaps of well-deformed and superdeformed nuclei are investigated using the particle-number conserving (PNC) formalism for the cranked shell model, in which the blocking effects are treated exactly and no spurious states appear. Both the rotational frequency ω-dependence and seniority ν-dependence of the pairing gap Δ-bar are addressed. For the ground-state bands of even-even nuclei, PNC calculations show that in general Δ-bar decreases with increasing ω, but the ω-dependence is much weaker than that calculated by the number-projected Hartree-Fock-Bogolyubov (NHFB) approach. For the multi quasiparticle bands (seniority ν > 2), the pairing gaps keep almost ω-independent. As a function of the seniority ν, the bandhead pairing gaps Δ-bar (ν, ω = 0) decrease slowly with increasing ν. Even for the highest seniority ν bands identified so far, Δ-bar (ν, ω = 0) keep 70% larger than Δ-bar (ν = 0, ω = 0). (authors)

Nuclear pairing gaps of normally deformed and superdeformed nuclei are investigated using the particle-number-conserving (PNC) formalism for the cranked shell model, in which the blocking effects are treated exactly. Both rotational frequency ω dependence and seniority (number of unpaired particles) ν dependence of the pairing gap Δ-tilde are investigated. For the ground-state bands of even-even nuclei, PNC calculations show that, in general, Δ-tilde decreases with increasing ω, but the ω dependence is much weaker than that calculated by the number-projected Hartree-Fock-Bogolyubov approach. For the multiquasiparticle bands (seniority ν>2), the pairing gaps stay almost ω independent. As a function of the seniority ν, the bandhead pairing gaps Δ-tilde(ν,ω=0) decrease slowly with increasing ν. Even for the highest seniority ν bands identified so far, Δ-tilde(ν,ω=0) remains greater than 70% of Δ-tilde(ν=0,ω=0).

[The supervisor has a crucial role in the medical student's degree projects. Experiences from seven semesters at Karolinska Institutet].

Möller, Riitta; Shoshan, Maria; Ponzer, Sari

2015-01-13

In Sweden degree projects have a central role in evaluation of higher education, wherefore significant resources are spent on developing students' research competence. The undergraduate medical program at Karolinska Institutet introduced its degree project course in 2010. This paper gives an overview of the course and summarizes experiences from the first seven terms. In order to finalize their projects within one term, most students need substantial support. A highly structured course and frequent progress monitoring are advantageous. Other crucial factors are the quality of the supervision and students' verbal skills as well as support in scientific writing. In addition, increased awareness of the learning outcomes already at the beginning of the course may help students to achieve the expected results. Finally, students need to recognize their own responsibility for learning.

The rare close projection of two quasars on the sky provides the opportunity to study the host galaxy environment of a foreground quasar in absorption against the continuum emission of a background quasar. For over a decade the “Quasars probing quasars” series has utilized this technique to further the understanding of galaxy formation and evolution in the presence of a quasar at z > 2, resolving scales as small as a galactic disk and from bound gas in the circumgalactic medium to the diffuse environs of intergalactic space. Presented here is the public release of the quasar pair spectral database utilized in these studies. In addition to projected pairs at z > 2, the database also includes quasar pair members at z useful for small-scale clustering studies. In total, the database catalogs 5627 distinct objects, with 4083 lying within 5‧ of at least one other source. A spectral library contains 3582 optical and near-infrared spectra for 3028 of the cataloged sources. As well as reporting on 54 newly discovered quasar pairs, we outline the key contributions made by this series over the last 10 years, summarize the imaging and spectroscopic data used for target selection, discuss the target selection methodologies, describe the database content, and explore some avenues for future work. Full documentation for the spectral database, including download instructions, is supplied at http://specdb.readthedocs.io/en/latest/.

Beichner, Robert J.

2011-04-01

How do you keep a classroom of 100 undergraduates actively learning? Can students practice communication and teamwork skills in a large class? How do you boost the performance of underrepresented groups? The Student-Centered Active Learning Environment for Undergraduate Programs (SCALE-UP) Project has addressed these concerns. Because of their inclusion in a leading introductory physics textbook, project materials are used by more than 1/3 of all science, math, and engineering majors nationwide. The room design and pedagogy have been adopted at more than 100 leading institutions across the country. Physics, chemistry, math, astronomy, biology, engineering, earth sciences, and even literature classes are currently being taught this way. Educational research indicates that students should collaborate on interesting tasks and be deeply involved with the material they are studying. We promote active learning in a redesigned classroom for 100 students or more. (Of course, smaller classes can also benefit.) Class time is spent primarily on "tangibles" and "ponderables"--hands-on activities, simulations, and interesting questions. Nine students sit in three teams at round tables. Instructors circulate and engage in Socratic dialogues. The setting looks like a banquet hall, with lively interactions nearly all the time. Hundreds of hours of classroom video and audio recordings, transcripts of numerous interviews and focus groups, data from conceptual learning assessments (using widely-recognized instruments in a pretest/posttest protocol), and collected portfolios of student work are part of our rigorous assessment effort. Our findings (based on data from over 16,000 students collected over five years as well as replications at adopting sites) can be summarized as the following: 1) Female failure rate is 1/5 of previous levels, even though more is demanded of students. 2) Minority failure rate is 1/4 that seen in traditionally taught courses. 3) At-risk students are more

A One-year Case Study: Understanding the Rich Potential of Project-based Learning in a Virtual Reality Class for High School Students

Morales, Teresa M.; Bang, EunJin; Andre, Thomas

2013-10-01

This paper presents a qualitative case analysis of a new and unique, high school, student-directed, project-based learning (PBL), virtual reality (VR) class. In order to create projects, students learned, on an independent basis, how to program an industrial-level VR machine. A constraint was that students were required to produce at least one educational application of VR. This study incorporated in-depth classroom observations, interviews with students, analyses of student projects, and surveys of parents and teachers to examine the social and learning processes in the class, and the nature of content learning represented in student projects. The results demonstrated that PBL can be effective even with minimal teacher guidance. The findings substantiate an educational approach rich with promise, for at least some students, that deserves considerable additional study to maximize its powerful potentials for independent and peer-mentored learning.

Research Experience for Undergraduates (REU) programs commonly serve students already committed to careers in science. To spark student interest in the sciences early in their college career, the CIRES diversity initiative teamed with the Boulder Creek Critical Zone Observatory to build an REU for Colorado community college students. A group of 7 students was selected from consideration of diversity, prior training, and personal statements. Each student was paired with a research science mentor. Field excursions and team-building exercises filled the first week of the 8-week program. Students received weekly training in science communication, responsible conduct of research, use of spreadsheet and graphing software, and statistical analysis. Each student presented their research in a poster session, an oral presentation, and a written report. Several aspects of this pilot program worked well. The students formed a very supportive cohort, despite the fact that they were not in residence. Cohesion grew out of the immersion in field trips, and was reinforced with weekly check-ins. The trainings were essential for seeing projects through to written and oral presentations. Teaming students for fieldwork was an effective strategy to build support, and reduce mentor fatigue. Each student produced useful data. In the future, we would include a workshop on personal finances to address a clear need. Transportation support will be provided. A residential program might attract some but could preclude participation of students with families or other life-issues. Personal tutoring tailored to research projects would address low math skills. All 7 students completed the program; several elected to submit to the undergraduate virtual poster session at Fall AGU. Students all reported enormous personal and academic growth. Some are discussing transfer and graduate school opportunities with their mentors. The enthusiasm and appreciation of the students was unparalleled.

Microbial Murders Crime Scene Investigation: An Active Team-Based Learning Project that Enhances Student Enthusiasm and Comprehension of Clinical Microbial Pathogens.

Science.gov (United States)

Steel, J Jordan

2017-01-01

Microbial disease knowledge is a critical component of microbiology courses and is beneficial for many students' future careers. Microbiology courses traditionally cover core concepts through lectures and labs, but specific instruction on microbial diseases varies greatly depending on the instructor and course. A common project involves students researching and presenting a disease to the class. This method alone is not very effective, and course evaluations have consistently indicated that students felt they lacked adequate disease knowledge; therefore, a more hands-on and interactive disease project was developed called Microbial Murders. For this team-based project, a group of students chooses a pathogen, researches the disease, creates a "mugshot" of the pathogen, and develops a corresponding "crime scene," where a hypothetical patient has died from the microbe. Each group gives a presentation introducing the microbial pathogen, signs/symptoms, treatments, and overall characteristics. The students then visit each other's crime scenes to match the pathogen with the correct crime scene by critically thinking through the clues. This project has shown remarkable success. Surveys indicate that 73% of students thought the project helped them understand the material and 84% said it was worth their time. Student participation, excitement, understanding, and application of microbial disease knowledge have increased and are evident through an increase in course evaluations and in student assessment scores. This project is easy to implement and can be used in a wide variety of biology, microbiology, or health classes for any level (middle school through college).

RNA Secondary Structure Prediction by Using Discrete Mathematics: An Interdisciplinary Research Experience for Undergraduate Students

Science.gov (United States)

Ellington, Roni; Wachira, James

2010-01-01

The focus of this Research Experience for Undergraduates (REU) project was on RNA secondary structure prediction by using a lattice walk approach. The lattice walk approach is a combinatorial and computational biology method used to enumerate possible secondary structures and predict RNA secondary structure from RNA sequences. The method uses discrete mathematical techniques and identifies specified base pairs as parameters. The goal of the REU was to introduce upper-level undergraduate students to the principles and challenges of interdisciplinary research in molecular biology and discrete mathematics. At the beginning of the project, students from the biology and mathematics departments of a mid-sized university received instruction on the role of secondary structure in the function of eukaryotic RNAs and RNA viruses, RNA related to combinatorics, and the National Center for Biotechnology Information resources. The student research projects focused on RNA secondary structure prediction on a regulatory region of the yellow fever virus RNA genome and on an untranslated region of an mRNA of a gene associated with the neurological disorder epilepsy. At the end of the project, the REU students gave poster and oral presentations, and they submitted written final project reports to the program director. The outcome of the REU was that the students gained transferable knowledge and skills in bioinformatics and an awareness of the applications of discrete mathematics to biological research problems.

Examining student conceptions of the nature of science from two project-based classrooms

Science.gov (United States)

Moss, David M.

The purpose of this research was to develop descriptive accounts of precollege students' conceptions of the nature of science from two project-based classrooms, and track those conceptions over the course of an academic year. A model of the nature of science was developed and served as the criterion by which students' beliefs were evaluated. The model distinguishes between two major categories of science, the nature of the scientific enterprise and the nature of scientific knowledge. Five students were selected from each class and interviewed individually for 30-45 minutes each, six times over the year. Data from semi-structured, formal interviewing consisted of audio-recorded interviews which were transcribed verbatim. All passages were coded using codes which corresponded to the premises of the model of the nature of science. Passages in the transcripts were interpreted to develop a summary of the students' conceptions over the year. Qualitative methodologies, especially formal interviewing in conjunction with participant observation, were effective for uncovering students' conceptions of the nature of science, adding to the knowledge base in this field. The research design of the current study was a significant factor in explaining the inconsistencies seen between findings from this study and the literature. This study finds that participants at both classroom sites held fully formed conceptions of the nature of science for approximately 40 percent of the premises across the model. For two-thirds of the elements which comprise the premises, participants held full understandings. Participants held more complete understandings of the nature of scientific knowledge than the nature of the scientific enterprise. Most participants had difficulty distinguishing between science and non-science and held poor understandings of the role of questions in science. Students' beliefs generally remained unchanged over the year. When their conceptions did evolve, project

In 2006-2007 and 2007-2008, the authors pilot-tested a filmmaking project, (medical students filmed patients) to assess the project's potential to teach about the challenges of living with serious chronic illness. Two years of second-year medical students (N = 32) from The University of Arizona, working in groups of two or three, were paired with patients and filmed multiple home visits during eight months. Students edited their films to 7 to 10 minutes and added transitions, titles, and music. A mixed audience of students and faculty viewed the resulting 12 films in a "Video Slam." Faculty also used the films in the formal curriculum to illustrate teaching points related to chronic illness. Student filmmakers, on average, made 4.4 visits, collected 5.6 hours of film, and edited for 26.6 hours. Students reported that the project affected what they planned to cover in clinic visits, increased their plans to involve patients in care, enhanced their appreciation for patient-centered care, improved their knowledge of community resources, improved their understanding of allied health professionals' roles, and taught them about patients' innovative adaptations. Overall, students rated the project highly for its impact on their education (mean = 4.52 of 5). Student and faculty viewers of the films (N = 74) found the films compelling (mean = 4.95 of 5) and informative (mean = 4.93 of 5). The authors encountered the ethical dilemmas of deciding who controls the patients' recorded stories and navigating between patient anonymity/confidentiality and allowing patients to use their stories to teach.

In the spirit of Valentines Day, today well be exploring apparent pairs of galaxies in the distant, early universe. How can we tell whether these duos are actually paired galaxies, as opposed to disguised singles?Real Pair, or Trick of the Light?In the schematic timeline of the universe, the epoch of reionization is when the first galaxies and quasars began to form and evolve. [NASA]The statistics of merging galaxies throughout the universe reveal not only direct information about how galaxies interact, but also cosmological information about the structure of the universe. While weve observed many merging galaxy pairs at low redshift, however, its much more challenging to identify these duos in the early universe.A merging pair of galaxies at high redshift appears to us as a pair of unresolved blobs that lie close to each other in the sky. But spotting such a set of objects doesnt necessarily mean were looking at a merger! There are three possible scenarios to explain an observed apparent duo:Its a pair of galaxies in a stage of merger.Its a projection coincidence; the two galaxies arent truly near each other.Its a single galaxy being gravitationally lensed by a foreground object. This strong lensing produces the appearance of multiple galaxies.Hubble photometry of one of the three galaxy groups identified at z 8, with the galaxies in the image labeled with their corresponding approximate photometric redshifts. [Adapted from Chaikin et al. 2018]Hunting for Distant DuosIn a recent study led by Evgenii Chaikin (Peter the Great St. Petersburg Polytechnic University, Russia), a team of scientists has explored the Hubble Ultra Deep Field in search ofhigh-redshift galaxies merging during the epoch of reionization, when the first galaxies formed and evolved.Using an approach called the dropout technique, which leverages the visibility of the galaxies in different wavelength filters, Chaikin and collaborators obtain approximate redshifts for an initial sample of 7

Poverty, along with other factors such as unemployment, work and life stressors, interpersonal violence, and lack of access to high quality health and/or social services all play a role in determining who develops a mental illness and for whom those symptoms persist or worsen. Senior nursing student preparing to enter the field and working in a service learning capacity may be able to influence early recovery and symptom abatement among those most vulnerable to mental illness. A consortium of community stakeholders and researchers collaboratively designed a 10-week mental health promotion project called the Health Advocacy Project (HAP). The project combines case management and system navigation support delivered by trained and highly supervised nursing students to individuals experiencing major depressive disorder (MDD) and/or post-traumatic stress disorder (PTSD). In this article, we present the findings of a qualitative fidelity evaluation that examines the effectiveness of nursing students in delivering the health advocacy intervention at the level and with the intensity originally intended. The findings demonstrate how the services of senior nursing students may be optimized to benefit our healthcare system and populations most at risk for developing MDD and PTSD.

Swan, Amy K.

2011-12-01

This qualitative study explored the experiential and contextual factors that shaped female students' pathways into introductory project-based engineering classes at two community colleges and one four-year institution, as well as female students' experiences within and outside of these classes. The study was framed by Social Cognitive Career Theory (SCCT) (Lent, Brown & Hackett, 1996) and Bronfenbrenner's (1979) ecological systems theory. Findings were based on analyses of data gathered through multiple methods: observations; individual interviews with female students; focus group interviews with project teams; and document collection. The findings of this study revealed that while positive experiences with math or science were a likely pre-cursor to engineering interest, experiential learning appeared to be a more powerful force in fostering students' engineering interest. Specifically, participants developed an interest in engineering through academic, professional, and extracurricular engineering- and design-related activities that familiarized them with the tasks and skills involved in engineering work and helped them develop a sense of selfefficacy with regard to this work. Interest and self-efficacy, in turn, played a role in students' postsecondary educational decision-making processes, as did contextual factors including families and finances. This study's findings also showed that participants' project teams were a critically important microsystem within participants' ecological environments. Within this sometimes "chilly" microsystem, female students negotiated intrateam processes, which were in some cases affected by gender norms. Intrateam processes that influenced female students' project-based learning experiences included: interpersonal dynamics; leadership; and division of labor. This study also identified several ways in which the lived experiences of participants at the community colleges were different from, or similar to, those of participants

2014-12-01

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

Nelson, S. J.; Zoellick, B.; Davis, Y.; Lindsey, E.

2009-12-01

In 2007 the authors initiated a citizen science research project, supported with funding from the Maine Department of Education, designed to extend research at Acadia National Park to a broader geographic area while also providing high school students and teachers with an opportunity to engage in authentic research in cooperation with working scientists. The scientific focus of the work has been on providing information about the mercury burden of organisms at different trophic levels across different geographic and environmental settings. The pedagogical focus has been on providing students with immersion in a substantial, field-based project, including background research, hypothesis formulation, data collection and analysis, and presentation of research findings. Starting work with 6 teachers in two schools the first year, the project expanded to involve more than 20 teachers and 350 students in a dozen schools in its second year. In coming years, with support from NOAA and cooperation from other National Parks in the region, the project will expand to include work in other states along the coast of the Gulf of Maine. In this paper the authors describe evolution in the use of the Internet over the first two years of the project, a sharpened focus on professional development for teachers, survey results regarding student views of the nature of science, the importance of focusing on rigorous, useful data collection from an educational perspective, success in establishing that samples collected by students are useful in research, the disjuncture between scientific and pedagogical outcomes, an assessment of the value of student poster presentations, and lessons learned about preparation and use of curriculum support materials. The authors also describe future directions, which include an increased focus on professional development and student work with graphs, a narrower focus in sample collection, and increased use of the Internet to provide participating teachers

Density functional approach for pairing in finite size systems

International Nuclear Information System (INIS)

Hupin, G.

2011-09-01

The combination of functional theory where the energy is written as a functional of the density, and the configuration mixing method, provides an efficient description of nuclear ground and excited state properties. The specific pathologies that have been recently observed, show the lack of a clear underlying justification associated to the breaking and the restoration of symmetries within density functional theory. This thesis focuses on alternative treatments of pairing correlations in finite many body systems that consider the breaking and the restoration of the particle number conservation. The energy is written as a functional of a projected quasi-particle vacuum and can be linked to the one obtained within the configuration mixing framework. This approach has been applied to make the projection either before or after the application of the variational principle. It is more flexible than the usual configuration mixing method since it can handle more general effective interactions than the latter. The application to the Krypton isotopes shows the feasibility and the efficiency of the method to describe pairing near closed shell nuclei. Following a parallel path, a theory where the energy is written as a functional of the occupation number and natural orbitals is proposed. The new functional is benchmarked in an exactly solvable model, the pairing Hamiltonian. The efficiency and the applicability of the new theory have been tested for various pairing strengths, single particle energy spectra and numbers of particles. (author)

A Scaffold Analysis Tool Using Mate-Pair Information in Genome Sequencing

Directory of Open Access Journals (Sweden)

Pan-Gyu Kim

2008-01-01

Full Text Available We have developed a Windows-based program, ConPath, as a scaffold analyzer. ConPath constructs scaffolds by ordering and orienting separate sequence contigs by exploiting the mate-pair information between contig-pairs. Our algorithm builds directed graphs from link information and traverses them to find the longest acyclic graphs. Using end read pairs of fixed-sized mate-pair libraries, ConPath determines relative orientations of all contigs, estimates the gap size of each adjacent contig pair, and reports wrong assembly information by validating orientations and gap sizes. We have utilized ConPath in more than 10 microbial genome projects, including Mannheimia succiniciproducens and Vibro vulnificus, where we verified contig assembly and identified several erroneous contigs using the four types of error defined in ConPath. Also, ConPath supports some convenient features and viewers that permit investigation of each contig in detail; these include contig viewer, scaffold viewer, edge information list, mate-pair list, and the printing of complex scaffold structures.

There have been a number of crowdsourcing projects to support people with disabilities. However, there is little exploration of what motivates people to participate in such crowdsourcing projects. In this study we investigated how different motivational factors can affect the participation of people in a crowdsourcing project to support visually disabled students. We are developing "DescribeIT", a crowdsourcing project to support blind and partially students by having sighted people describe images in digital learning resources. We investigated participants' behavior of the DescribeIT project using three conditions: one intrinsic motivation condition and two extrinsic motivation conditions. The results showed that participants were significantly intrinsically motivated to participate in the DescribeIT project. In addition, participants' intrinsic motivation dominated the effect of the two extrinsic motivational factors in the extrinsic conditions.

The Undergraduate Student Instrumentation Project (USIP) is a NASA program to engage undergraduate students in rigorous scientific research, for the purposes of innovation and developing the next generation of professionals for an array of fields. The program is student led and executed from initial ideation to research to the design and deployment of scientific payloads. The University of Houston has been selected twice to participate in the USIP programs. The first program (USIP_UH I) ran from 2013 to 2016. USIP_UH II started in January of 2016, with funding starting at the end of May. USIP_UH I (USIP_UH II) at the University of Houston was (is) composed of eight (seven) research teams developing six (seven), distinct, balloon-based scientific instruments. These instruments will contribute to a broad range of geophysical sciences from Very Low Frequency recording and Total Electron Content to exobiology and ozone profiling. USIP_UH I had 12 successful launches with 9 recoveries from Fairbanks, AK in March 2015, and 4 piggyback flights with BARREL 3 from Esrange, Kiruna, Sweden in August, 2015. USIP_UH II had 8 successful launches with 5 recoveries from Fairbanks, AK in March 2017, 3 piggyback flights with BARREL 4 from Esrange, Kiruna, Sweden in August, 2016, and 1 flight each from CSBF and UH. The great opportunity of this program is capitalizing on the proliferation of electronics miniaturization to create new generations of scientific instruments that are smaller and lighter than ever before. This situation allows experiments to be done more cheaply which ultimately allows many more experiments to be done.

Soil and its selected properties on the example of an individual project for the grade 1 students of upper secondary school

2014-05-01

According to the requirements of the new core curriculum for Chemistry, students shall acquire knowledge through research and use the acquired chemical knowledge in their everyday life. However, in the recommended conditions and mode of implementation of the curriculum it is confirmed, that students' autonomous observation constitutes a basis for experiencing, inferences, analysis, and generalisations of phenomena [1]. It is obvious that teachers should create proper didactic situations, during which school students have a possibility to develop attitudes, skills and competences. More about competences we can find in the recommendations of the European Parliament and of the Council of 18 December 2006 on key competences for lifelong learning [2]. The detailed content of the core curriculum for the subject of chemistry at the fourth stage of education (basic level), we read: "4. Chemistry of soil. Student: 1) explains what the sorption properties of the soil are; plans and performs .... study of the sorption properties of the soil. " In the school year 2012/2013 chemistry teachers decided to offer students of a first-class to be involved in the project "Soil in the chemist's eye." It was considered that the method of the project is known from lower secondary school level and the teacher will have an opportunity to recognize students, who in the future, will choose the class with advanced chemistry program and determine the level of their skills, in particular the research skills. What we can offer to students does not necessarily take place in a well-equipped chemical laboratory. On the contrary, this process should be based on the well-known school subjects items, articles, objects and phenomena, which students meet in everyday life. The well-chosen methodologies and ways of showing the world will be, more understandable and skills will become a permanent part of the students, knowledge. Project characterization: a) The proposed project is problem-oriented, in

Importance of interlayer pair tunneling: A variational perspective

International Nuclear Information System (INIS)

Medhi, Amal; Basu, Saurabh

2011-01-01

We study the effect of interlayer pair tunneling in a bilayer superconductor where each layer is described by a two dimensional t-J model and the two layers are connected by the Josephson pair tunneling term. We study this model using a grand canonical variational Monte Carlo (GVMC) method, for which we develop a new algorithm to perform Monte Carlo simulation of a system with fluctuating particle number. The variational wavefunction is taken to be the product of two Gutzwiller projected d-wave BCS wavefunctions with variable particle densities, one for each layer. We calculate the energy of the above state as a function of the d-wave superconducting gap parameter, Δ. We find that the interlayer pair tunneling energy, E perpendicular shows interesting variation with Δ. E perpendicular tends to enhance the optimal value of Δ, thereby the superconducting pairing. However the magnitude of the tunneling energy is found to be too small to have any appreciable effect on the physical properties. While the result is supported by early experiments and hence may appear known to the community, the current work presents a new approach to the problem and confirms the diminished role of interlayer pair tunneling by directly calculating its contribution to superconducting condensation energy.

Numerical studies of pair creation in counterpropagating laser fields

Ruf, Matthias

2009-05-27

Pair creation from vacuum induced by electromagnetic fields is probably one of the most intriguing phenomena in physics. If the fields are sufficiently strong, the QED vacuum become unstable. Due to the remarkable progress in laser technology during recent years an experimental investigation of pair creation by pure laser light is coming into reach. The focus of this thesis is on pair creation in counterpropagating laser beams. The pair creation probability is calculated employing the numerically obtained solutions of the Dirac equation. This numerical ansatz has the capability of calculating the momentum distribution of the created pairs in a single propagation, for pure time dependent field configurations. Furthermore, it allows to take the magnetic component of the laser fields into account, which is usually neglected. The latter strongly affects the creation process at high laser frequency. The involved numerical calculations are rather time consuming, therefore the second project of this thesis was to develop a highly efficient code for solving relativistic quantum mechanical problems. This is accomplished by adopting the split-operator method to the Klein-Gordon equation. Here the possibility arises to use parallel computing. However the corresponding spin-statistics becomes crucial in the case of pair creation, demonstrated in several examples. (orig.)

Covering All the Bases in Genetics: Simple Shorthands and Diagrams for Teaching Base Pairing to Biology Undergraduates

Directory of Open Access Journals (Sweden)

Sergei Kuchin

2011-03-01

Full Text Available Explaining base pairing is an important element in teaching undergraduate genetics. I propose a teaching approach that aims to close the gap between the mantra “A pairs with T, and G pairs with C” and the “intimidating” chemical diagrams. The approach offers a set of simple “shorthands” for the key bases that can be used to quickly deduce all canonical and wobble pairs that the students need to know. The approach can be further developed to analyze mutagenic mismatch pairing.

In the lower/middle troposphere, {H2O,δD} pairs are good proxies for moisture pathways; however, their observation, in particular when using remote sensing techniques, is challenging. The project MUSICA (MUlti-platform remote Sensing of Isotopologues for investigating the Cycle of Atmospheric water) addresses this challenge by integrating the remote sensing with in situ measurement techniques. The aim is to retrieve calibrated tropospheric {H2O,δD} pairs from the middle infrared spectra measured from ground by FTIR (Fourier transform infrared) spectrometers of the NDACC (Network for the Detection of Atmospheric Composition Change) and the thermal nadir spectra measured by IASI (Infrared Atmospheric Sounding Interferometer) aboard the MetOp satellites. In this paper, we present the final MUSICA products, and discuss the characteristics and potential of the NDACC/FTIR and MetOp/IASI {H2O,δD} data pairs. First, we briefly resume the particularities of an {H2O,δD} pair retrieval. Second, we show that the remote sensing data of the final product version are absolutely calibrated with respect to H2O and δD in situ profile references measured in the subtropics, between 0 and 7 km. Third, we reveal that the {H2O,δD} pair distributions obtained from the different remote sensors are consistent and allow distinct lower/middle tropospheric moisture pathways to be identified in agreement with multi-year in situ references. Fourth, we document the possibilities of the NDACC/FTIR instruments for climatological studies (due to long-term monitoring) and of the MetOp/IASI sensors for observing diurnal signals on a quasi-global scale and with high horizontal resolution. Fifth, we discuss the risk of misinterpreting {H2O,δD} pair distributions due to incomplete processing of the remote sensing products.

In this paper we analyze three quantum operations in two dimensional conformal field theories (CFTs): local projection measurements, creations of partial entanglement between two CFTs, and swapping of subsystems between two CFTs. We also give their holographic duals and study time evolutions of entanglement entropy. By combining these operations, we present an analogue of quantum teleportation between two CFTs and give its holographic realization. We introduce a new quantity to probe tripartite entanglement by using local projection measurement.
