  3. Knowledge Retention for Computer Simulations: A study comparing virtual and hands-on laboratories

    NASA Astrophysics Data System (ADS)

    Croom, John R., III

    The use of virtual laboratories has the potential to change physics education. These low-cost, interactive computer activities interest students, allow for easy setup, and give educators a way to teach laboratory based online classes. This study investigated whether virtual laboratories could replace traditional hands-on laboratories and whether students could retain the same long-term knowledge in virtual laboratories as compared to hands-on laboratories. This study is a quantitative quasi-experiment that used a multiple posttest design to determine if students using virtual laboratories would retain the same knowledge as students who performed hands-on laboratories after 9 weeks. The study was composed of 336 students from 14 school districts. Students had their performances on the laboratories and their retention of the laboratories compared to a series of factors that might have affected their retention using a pretest and two posttests, which were compared using a t test. The results showed no significant difference in short-term learning between the hands-on laboratory groups and virtual laboratory groups. There was, however, a significant difference (p = .005) between the groups in long-term retention; students in the hands-on laboratory groups retained more information than those in the virtual laboratory groups. These results suggest that long-term learning is enhanced when a laboratory contains a hands-on component. Finally, the results showed that both groups of students felt their particular laboratory style was superior to the alternative method. The findings of this study can be used to improve the integration of virtual laboratories into science curriculum.

  4. Hands-on astronomy activities for the elementary school

    Lutz, T.E.; Horne, J.C.

    1994-12-31

    We held a series of astronomy workshops for local school teachers using astronomy activities from a course we give for Elementary Education majors. The school teachers provide us with feedback about successes and failures. Then we try the revised activities in the classroom. Via this in-service and pre-service feedback, the astronomy laboratory activities in the course have been completely revised over the last three years. The activities we use are almost entirely hands-on. The activities include use of log book (or journal) for describing outside-of-class observations of sunsets, phases of the moon, portable sundial, and the somewhat unique method we use to teach the constellations. In addition, all laboratory activity records are kept in the log book. Laboratory activities cover the use of fists to measure degrees, constellations, phases of the moon, relative distances and size of planets, Invent an Alien, lenses, images and telescopes, and the making of a comet. In our poster, based roughly on the theme of the seasons, we will describe a portable, multi-user sundial, length of the day display using newspaper data, two temperature/season activities, and a model demonstration of why the sundial shadows behave as they do.

    The Laboratorio Didattica e Divulgazione Scientifica of the Istituto Nazionale di Geofisica e Vulcanologia (INGV's Educational and Outreach Laboratory) organized activity with kids to convey scientific knowledge and to promote research on Earth Science, focusing on volcanic and seismic hazard. The combination of games and learning in educational activity can be a valuable tool for study of complex phenomena. Hands-on activity may help in engage kids in a learning process through direct participation that significantly improves the learning performance of children. Making learning fun motivate audience to pay attention on and stay focused on the subject. We present the experience of the hand-on laboratory "Laboratorio goloso per bambini curiosi di scienza (a delicious hands-on laboratory for kids curious about science)", performed in Frascati during the 2013 European Researchers' Night, promoted by the European Commission, as part of the program organized by the Laboratorio Didattica e Divulgazione Scientifica in the framework of Associazione Frascati Scienza (http://www.frascatiscienza.it/). The hand-on activity were designed for primary schools to create enjoyable and unusual tools for learning Earth Science. During this activity kids are involved with something related to everyday life, such as food, through manipulation, construction and implementation of simple experiments related to Earth dynamics. Children become familiar with scientific concepts such as composition of the Earth, plates tectonic, earthquakes and seismic waves propagation and experience the effect of earthquakes on buildings, exploring their important implications for seismic hazard. During the activity, composed of several steps, participants were able to learn about Earth inner structure, fragile lithosphere, waves propagations, impact of waves on building ecc.., dealing with eggs, cookies, honey, sugar, polenta, flour, chocolate, candies, liquorice sticks, bread, pudding and sweets. The activity was successful as more than 500 kids of different ages participated with great enthusiasm, as well as they parents, and gave the chance to explore and manipulate even complex scientific arguments without getting the feeling of having doing this.

  12. At-risk children's use of reflection and revision in hands-on experimental activities

    NASA Astrophysics Data System (ADS)

    Petrosino, Anthony J., Jr.

    The goal of this study was to investigate the effects of incorporating opportunities for reflection and revision in hands-on science instruction which emphasized experimentation using model rockets. The participants were low achieving sixth grade summer school students (n = 23) designated as at-risk for school failure by their district. The group was asked a series of interview questions based on work by Schauble et al. (1995) relating to experimentation. The interviews took place over three distinct time points corresponding to a "hands-on only" condition, a "hands-on with reflection and revision" condition and a "hands-on with repeated reflection and revision" condition. A Friedman's Two-Way Analysis of Variance by Ranks indicate students score low at first with traditional hands-on instruction but improve significantly with opportunities to reflect and revise their experiments. In addition, a sociocultural analysis was conducted during the summer school session to assess the model rocket activity as an apprenticeship, as guided participation and as participatory appropriation using a framework established by Rogoff (1994). Finally, a survey (the Classroom Environment Survey) was administered to the students measuring five constructs consistent with a constructivist classroom: participation, autonomy, relevance, commitment to learning and disruptions to learning. Analysis indicate students in the summer school model rocket intervention experienced a greater sense of constructivist principles during the activity than a similar comparison group utilizing reform minded instruction but not including opportunities for reflection and revision cycles. This research provides important evidence that, like scientists, students in school can learn effectively from extended practice in a varied context. Importantly, the data indicate that hands-on instruction is best utilized when opportunities for reflection and revision are made explicit. Implications are discussed related to designing instruction, the incorporation of computer supported scaffolding and implications for future research.

    Frequent reports of laboratory- (and hospital-) acquired infection suggest a deficiency in safety training or lack of compliance. To assess the need for continuing education (CE) addressing this problem, an original education needs assessment survey was designed and administered to medical technologists (med-techs) in Northeast Ohio. Survey results were used to design a learner-centered training curriculum (for example, Lab Safety and Bioterrorism Readiness trainings) that engaged med-techs in active learning, integrative peer-to-peer teaching, and hands-on exercises in order to improve microbiology safety knowledge and associated laboratory techniques. The Lab Safety training was delivered six times and the Bioterrorism Readiness training was delivered five times. Pre/posttesting revealed significant gains in knowledge and techniques specific to laboratory safety, security, risk assessment, and bioterrorism readiness amongst the majority of med-techs completing the CE trainings. The majority of participants felt that the hands-on exercises met their needs and that their personal laboratory practices would change as a result of the training course, as measured by attitudinal surveys. We conclude that active learning techniques and peer education significantly enhance microbiology learning amongst participating med-techs. PMID:23914281

    Outreach informed by scientific research plays an important role in fostering interest in science by making science and scientists accessible, fun, and interesting. Developing an interest in science in young, elementary-aged students through outreach is a rewarding endeavor for researchers, in that audiences are usually receptive, requirements for broader impacts are met, and bonds are formed between researchers and members of their local and surrounding communities. Promoting such interest among young students is imperative not only for an individual researcher's own self interest, but also for the strength of American science and innovation moving forward, and is the responsibility of the current generation of scientists. Developing genuine and successful inquiry-based, hands-on activities for elementary-aged students is outside the expertise of many researchers. Partnering with an informal education learning center (i.e. science museum or after-school program) provides researchers with the expertise they might be lacking in such endeavors. Here, we present a series of polar-, engineering- and microbiology-themed hands-on activities that have been developed by researchers at a government lab in partnership with a local science museum. Through a series of workshops, the science education staff at the museum provided researchers with background and instruction on inquiry and hands-on activities, and then collaborated with the researchers to develop activities which were later demonstrated at the museum to museum-goers. Education staff provided feedback about the presentation of the activities for further refinement. The program provided an opportunity for researchers to develop fun, on-target and age-appropriate science activities for elementary-aged students, an audience for outreach, and enabled general public audiences the chance to interact with researchers and scientists in an informal setting.

  18. Informal Activities with Lasers, Lights, and Lenses: The Hands-On Optics Project

    NASA Astrophysics Data System (ADS)

    Pompea, S. M.; Sparks, C. E.; Sparks, R. T.

    2005-12-01

    The Hands-On Optics project began as a follow-up to the 2001 NSF planning grant "Optics Education -- A Blueprint for the 21st Century", which described the value of informal science programs in addressing the disconnect between the ubiquity of optics in everyday life and the noticeable absence of optics education in K-12 curricula and in informal science education programs. Key partners in the project are NOAO, SPIE-The International Society for Optical Engineering, and the Optical Society of America (OSA). The informal instructional materials created by the project are distributed through science centers nationwide and through the Mathematics, Engineering, Science Achievement Program (MESA) in a number of states, including Arizona, California, Washington, and Maryland. A key part of the project is the involvement, modeled after Project ASTRO, of optics professionals currently engaged in outreach activities and programs. Optics professionals (termed optics resource volunteers) are teamed with MESA and science center educators in implementing the program. These hands-on, high-interest, standards-connected activities and materials provide 6, three-hour-long optics activity modules that can be used in a variety of informal settings. We will describe the techniques used at NOAO to train educators, parents, and optics professionals who will work with the HOO activities as well as the different approaches needed for different informal education programs, ranging from Saturday programs, after-school programs, and science center programs. NOAO is developing the six modules and associated kits as well as competitions that have broad appeal to 12-year olds. Hands-On Optics: Making an Impact with Light (HOO) is a collaborative NSF-funded four-year informal science education program to excite students about science by actively engaging them in optics activities. NOAO is operated by the Association of Universities for Research in Astronomy (AURA), Inc. under cooperative agreement with the National Science Foundation.

  19. Meta-analysis of the effectiveness of computer-based laboratory versus traditional hands-on laboratory in college and pre-college science instructions

    Onuoha, Cajetan O.

    The purpose of this research study was to determine the overall effectiveness of computer-based laboratory compared with the traditional hands-on laboratory for improving students' science academic achievement and attitudes towards science subjects at the college and pre-college levels of education in the United States. Meta-analysis was used to synthesis the findings from 38 primary research studies conducted and/or reported in the United States between 1996 and 2006 that compared the effectiveness of computer-based laboratory with the traditional hands-on laboratory on measures related to science academic achievements and attitudes towards science subjects. The 38 primary research studies, with total subjects of 3,824 generated a total of 67 weighted individual effect sizes that were used in this meta-analysis. The study found that computer-based laboratory had small positive effect sizes over the traditional hands-on laboratory (ES = +0.26) on measures related to students' science academic achievements and attitudes towards science subjects (ES = +0.22). It was also found that computer-based laboratory produced more significant effects on physical science subjects compared to biological sciences (ES = +0.34, +0.17).

  20. Alignment of Hands-on STEM Engagement Activities with Positive STEM Dispositions in Secondary School Students

    Christensen, Rhonda; Knezek, Gerald; Tyler-Wood, Tandra

    2015-12-01

    This study examines positive dispositions reported by middle school and high school students participating in programs that feature STEM-related activities. Middle school students participating in school-to-home hands-on energy monitoring activities are compared to middle school and high school students in a different project taking part in activities such as an after-school robotics program. Both groups are compared and contrasted with a third group of high school students admitted at the eleventh grade to an academy of mathematics and science. All students were assessed using the same science, technology, engineering and mathematics (STEM) dispositions instrument. Findings indicate that the after-school group whose participants self-selected STEM engagement activities, and the self-selected academy of mathematics and science group, each had highly positive STEM dispositions comparable to those of STEM professionals, while a subset of the middle school whole-classroom energy monitoring group that reported high interest in STEM as a career, also possessed highly positive STEM dispositions comparable to the STEM Professionals group. The authors conclude that several different kinds of hands-on STEM engagement activities are likely to foster or maintain positive STEM dispositions at the middle school and high school levels, and that these highly positive levels of dispositions can be viewed as a target toward which projects seeking to interest mainstream secondary students in STEM majors in college and STEM careers, can hope to aspire. Gender findings regarding STEM dispositions are also reported for these groups.

  4. Hands-on Activities Tie Science Ed Standards to Space Weather on Windows to the Universe

    NASA Astrophysics Data System (ADS)

    Russell, R. M.; Johnson, R. M.

    2008-12-01

    The Windows to the Universe project includes a large web site with extensive user traffic as well as program of professional development workshops for teachers. In the past 5 years we have conducted 18 workshops dedicated exclusively to space weather and magnetism serving 573 total attendees. This talk describes our pedagogical approach of blending hands-on activities, covering basic concepts of magnetism, with visually- rich presentations of space weather topics in order to encourage teachers to incorporate space weather themes into their classroom teaching. Basic understanding of physical science themes of magnetism, electricity, forces, and motion are well represented in science education standards. Hands-on activities touching upon these themes simultaneously fulfill a teacher's need to cover topics in the standards and prepare students to comprehend more abstract representations of more complex systems relevant to space weather. Simply put, a student who has traced field lines around a bar magnet using a simple magnetometer is much better equipped to comprehend portrayals (images and animations) of complex magnetic fields associated with space weather phenomena. Thus, one of our main approaches to space weather education has been to encourage students to explore basic physical science concepts (as outlined in education standards) via hands-on activities and then to link those simple principles to more complex and visually captivating representations of space weather phenomena. We employ two other approaches to making the connections between standards-based themes that teachers must cover and concepts that are key to the study of space weather. The first is to tap heavily into "societal impacts" elements of education standards. Space weather presents numerous instances in which phenomena of scientific interest - such as radiation hazards to spacecraft and astronauts, communications disruptions, and surges in electrical power systems - have implications for modern society. The second is to point out space weather "case studies" in which key principles from various scientific disciplines come to bear. Radiation danger associated with space weather provides one such case, bringing together knowledge of energy, forces, and motion from the physical sciences with concepts like mutation, cell repair, and cancer from the life sciences. The aurora present another rich case, combining ideas of spectroscopy and energy transitions in atoms with the chemistry of Earth's atmosphere and Earth science concepts of atmospheric structure.

    2005-12-01

    Experimental work, using state of the art instrumentation, is integrated with lectures in a "real life", learning by discovery approach, in the Ion-Solid Interactions graduate/undergraduate course offered by the Department of Physics of the University of Central Florida. The lecture component of the course covers the underlying physical principles, and related scientific and technological applications, associated with the interaction of energetic ions with matter. In the experimental section the students form small groups and perform a variety of projects, experimental and computational, as part of a participative, inquiry oriented, learning process. In the most recent offering of the class, the students deposited a compound semiconductor thin film by dual-gun sputtering deposition, where each group aimed at a different stoichiometry of the same compound (Zn1-xSxOy). Then they analyzed the composition using Rutherford backscattering spectrometry, measured electrical transport properties using Hall effect and conductivity measurements, and determined the band gap using spectrophotometry. Finally the groups shared their results and each wrote a 'journal-like' technical article describing the entire work. In a different assignment, each group also developed a Monte Carlo computer program ('TRIM-like') to simulate the penetration of ions into a solid, in ion implantation, calculating the stopping cross-sections with approximate models, taught in class, which can be analytically solved. The combination of classroom/laboratory activities is very well received by the students. They gain real life experience operating state of the art equipment, and working in teams, while performing research-like projects, and simultaneously they learn the theoretical foundations of the discipline.

    2015-04-01

    GeoBus (www.geobus.org.uk) is an educational outreach project that was developed in 2012 by the Department of Earth and Environmental Sciences at the University of St Andrews, and it is sponsored jointly by industry and the UK Research Councils (NERC and EPSRC). The aims of GeoBus are to support the teaching of Earth Science in secondary schools by providing teaching resources that are not readily available to educators, to inspire young learners by incorporating new science research outcomes in teaching activities, and to provide a bridge between industry, higher education institutions, research councils and schools. Since its launch, GeoBus has visited over 160 different schools across the length and breadth of Scotland. Just under 35,000 pupils have been involved in practical hands-on Earth science learning activities since the project began in 2012, including many in remote and disadvantaged regions. The resources that GeoBus brings to schools include all the materials and equipment needed to run 50 - 80 minute workshops, and half- or whole-day Enterprise Challenges and field excursions. Workshops are aimed at a class of up to 30 pupils and topics include minerals, rocks, fossils, geological time, natural resources, climate change, volcanoes, earthquakes, and geological mapping. As with all GeoBus activities, the inclusion of equipment and technology otherwise unavailable to schools substantially increases the engagement of pupils in workshops. Field excursions are increasingly popular, as many teachers have little or no field trainng and feel unable to lead this type of activity. The excursions comprise half or full day sessions for up to 30 pupils and are tailored to cover the local geology or geomorphology. Enterprise Challenge are half or full day sessions for up to 100 pupils. Topics include "Journey to Mars", "Scotland's Rocks", "Drilling for Oil", and "Renewable Energy". Both of the energy Enterprise Challenges were designed to incorporates ideas and datasets from Maersk Oil Ltd, Centrica Upstream Research and Shell. Pupils are assigned roles (geologists, geophysicists and engineers) and work in teams on the datasets provided. Journey to Mars involves pupils learning about remote sensing techniques, the technology that the Mars Science Laboratory carries, and use NASA data to explore how we search for signs of water and life on Mars. These challenges develop geological and research skills, team working, spatial (3D) and mathematical skills, and provide insight on career opportunities in Earth and space sciences. In order to keep all GeoBus materials as current and engaging as possible, university academics from different disciplines, students and industry professionals are all involved in developing its resources.

  11. Progress of Systematic Hands on Devices for Active Learning Methods by Visualizing ICT Tools in Physics with Milliseconds Resolution

    Kobayashi, Akizo; Okiharu, Fumiko

    We are developing various systematic hands on devices for progress of active learning (AL) to improve students' conceptual understanding in physics laws. We are promoting AL methods in physics education for getting deeper conceptual understanding by using various ICT-based hands on devices and using visualizing ICT tools with milliseconds resolution. Here we investigate AL modules on collisions of big balloon pendulum with another known mass pendulum to get directly the air mass in the big balloon. We also discuss on Newton's laws of blowgun darts systems by using tapioca straws where we get definite works and energy just proportional to the length of the pipes of connected tapioca straws. These AL plans by using modules of big balloon system and blowgun-darts system are shown to be very effective for deeper conceptual understanding of Newton's Laws in almost frictionless worlds.

    Often computer simulation environments present students with an idealized version of the real world which can affect students' conceptual understanding. In this study we investigate the effects of completing an experiment in mechanics using this ideal world as compared to an identical experiment in the real world. Students in three of five conceptual physics laboratory sections completed the physical experiment while the other two sections performed the virtual experiment. The experiments were part of a unit on simple machines from the CoMPASS curriculum [1] which integrates hypertext-based concept maps in a design-based context. There was no statistically significant difference between the pre and post data of the students in the two groups. Students who performed the virtual experiment were able to answer questions dealing with work and potential energy more correctly, though neither group was able to offer sound reasoning to support their answers.

  8. Teaching chemistry and other sciences to blind and low-vision students through hands-on learning experiences in high school science laboratories

    NASA Astrophysics Data System (ADS)

    Supalo, Cary Alan

    2010-11-01

    Students with blindness and low vision (BLV) have traditionally been underrepresented in the sciences as a result of technological and attitudinal barriers to equal access in science laboratory classrooms. The Independent Laboratory Access for the Blind (ILAB) project developed and evaluated a suite of talking and audible hardware/software tools to empower students with BLV to have multisensory, hands-on laboratory learning experiences. This dissertation focuses on the first year of ILAB tool testing in mainstream science laboratory classrooms, and comprises a detailed multi-case study of four students with BLV who were enrolled in high school science classes during 2007--08 alongside sighted students. Participants attended different schools; curricula included chemistry, AP chemistry, and AP physics. The ILAB tools were designed to provide multisensory means for students with BLV to make observations and collect data during standard laboratory lessons on an equivalent basis with their sighted peers. Various qualitative and quantitative data collection instruments were used to determine whether the hands-on experiences facilitated by the ILAB tools had led to increased involvement in laboratory-goal-directed actions, greater peer acceptance in the students' lab groups, improved attitudes toward science, and increased interest in science. Premier among the ILAB tools was the JAWS/Logger Pro software interface, which made audible all information gathered through standard Vernier laboratory probes and visually displayed through Logger Pro. ILAB tools also included a talking balance, a submersible audible light sensor, a scientific talking stopwatch, and a variety of other high-tech and low-tech devices and techniques. While results were mixed, all four participating BLV students seemed to have experienced at least some benefit, with the effect being stronger for some than for others. Not all of the data collection instruments were found to reveal improvements for all of the participating students, but each of the types of data sets provided evidence of benefit for varying subgroups of participants. It is the expectation of the ILAB team that continuing to implement adaptive/assistive technologies for BLV students in science laboratory classrooms will foster enhanced opportunities in science classes and professions.

  10. Hands-On Activities: A New Instructional Method for a Fluid Mechanics Course---Never Underestimate the Teaching Power of Jell-O RTM

    NASA Astrophysics Data System (ADS)

    Albers, Lynn Alwine

    Background In order to eliminate the fear-factor associated with learning FluidMechanics, a new instructional method was created. The new method is neatly packaged into hands-on activities (as defined in this dissertation) in order to ease implementation and dissemination into an engineering class. Because of variations in learning and teaching styles of students and lecturers [34], the hands-on activities are designed to help the lecturer communicate key concepts to a wider spectrum of students. Typically engineering lectures are biased towards intuitive, verbal, reflective and sequential learners whereas few engineering students fall into these categories. [35] The hands-on activities are meant to bridge the communication gap resulting in a positive educational experience. Purpose In order to assess the impact of the new instructional method, a new engineering education experimental design was created. Engineering Education research is very interdisciplinary in nature and therefore requires cooperation from multiple Colleges including, but not limited to, Engineering, Education, and Science (Statistics). Design/Method Two groups of engineering students were allocated to test the hypothesis, "Does being exposed to hands-on activities (a new instructional method) in a section of MAE 308 - Fluid Mechanics result in higher student achievement?" Comparison of the quiz results between the control group and experimental group assessed the effectiveness of the hands-on activities. The problems within each quiz correlated to a level of Bloom's Taxonomy. A comparison of the results on the problems assessed which level of Bloom's were impacted. NHST was performed to determine statistical significance while the effect size was calculated to determine practical significance. Results The hands-on activities have a positive effect on learning. 3.30% more students per class perform better on each problem on each quiz. The hands-on activity, Rainbow Layer Cake, was a superstar proving statistically significant (p < 0.05) and meaningful with a 1.35 effect size. Thus showing that an activity was more effective at teaching a new concept than lecturing alone. Students in the experimental group performed better on problems designed to test Bloom's levels of understanding, analyzing and evaluating (levels 2, 4, and 5). Conclusions The hands-on activities are effective and should be developed for more concepts within all engineering courses. They are valuable tools to aid with teaching and can be easily implemented and disseminated to help make the engineering educational experience more positive.

    Grantham, Vesper; Martin, Chris; Schmitz, Casey

    2009-12-01

    Hands-on or active learning is important in nuclear medicine education. As more curricula start to require greater standards and as distance education expands, the effective use of laboratories in nuclear medicine education remains important in physics, instrumentation, and imaging but is often overlooked or underutilized. Laboratory exercises are a unique opportunity for nuclear medicine educators to facilitate students' critical thinking and problem-solving skills in a manner that often cannot occur in lectures or during online education. Given the lack of current laboratory tools and publications, there exists a requirement for nuclear medicine educators to develop, enhance, and monitor educational tools for laboratory exercises. Expanding technologies, variations in imaging and measurement systems, and the need to ensure that the taught technology is relevant to nuclear medicine students are issues faced by nuclear medicine educators. This article, based on principles of instructional design, focuses on the components and development of effective and enhanced nuclear medicine laboratories in our current educational environment.

  4. Exploring the Solar System Activities Outline: Hands-On Planetary Science for Formal Education K-14 and Informal Settings

    NASA Technical Reports Server (NTRS)

    Allen, J. S.; Tobola, K. W.; Lindstrom, M. L.

    2003-01-01

    Activities by NASA scientists and teachers focus on integrating Planetary Science activities with existing Earth science, math, and language arts curriculum. The wealth of activities that highlight missions and research pertaining to the exploring the solar system allows educators to choose activities that fit a particular concept or theme within their curriculum. Most of the activities use simple, inexpensive techniques that help students understand the how and why of what scientists are learning about comets, asteroids, meteorites, moons and planets. With these NASA developed activities students experience recent mission information about our solar system such as Mars geology and the search for life using Mars meteorites and robotic data. The Johnson Space Center ARES Education team has compiled a variety of NASA solar system activities to produce an annotated thematic outline useful to classroom educators and informal educators as they teach space science. An important aspect of the outline annotation is that it highlights appropriate science content information and key science and math concepts so educators can easily identify activities that will enhance curriculum development. The outline contains URLs for the activities and NASA educator guides as well as links to NASA mission science and technology. In the informal setting educators can use solar system exploration activities to reinforce learning in association with thematic displays, planetarium programs, youth group gatherings, or community events. Within formal education at the primary level some of the activities are appropriately designed to excite interest and arouse curiosity. Middle school educators will find activities that enhance thematic science and encourage students to think about the scientific process of investigation. Some of the activities offered are appropriate for the upper levels of high school and early college in that they require students to use and analyze data.

  5. Hands-on equals minds-on? A test of linkage between laboratory experience and measured achievement in an introductory college biology course

    NASA Astrophysics Data System (ADS)

    Racich, Leo Peter 3rd

    This study investigated the specific contribution of laboratory experience to student performance on achievement tests in an introductory college biology course. This required pre-medical student course (900 students) was separated by the biology department into a lecture course and a laboratory course, creating the study groups. The topics selected for treatment were in the field of molecular biology, including restriction enzyme manipulation and plasmid mapping of DNA sequences. Random samples (30 per group) of students enrolled in the lecture course and laboratory course, lecture course only, or laboratory course only were post-tested and second post-tested for objective test achievement in the topical field after laboratory participation. Student self-reported essays on topical concept gains from laboratory experience were categorized and analyzed in relation to achievement outcomes. A significant difference (F = 5.47, df = 2,87, alpha = .05) was present within the group by test achievement scores. Analysis showed no significant difference in test scores over time for the laboratory and lecture and laboratory only groups. There was a significant decline in test scores for the lecture only group over time. Analysis of 509 student self-reported essays showed approximately 18.5% reporting no abstract comprehension gain from the specific laboratory experience they chose to report. Approximately 8.3% of the essays reported increased confusion of topical concepts after participating in the laboratory exercise. The balance of the students (73.3%) reported increased topical concept understanding after laboratory exercise participation. The results suggest the importance of laboratory participation for long-term concept retention and the benefit of post-laboratory experience reflection time before objective testing. Direct instruction without laboratory experience appears to yield gains which are short term in nature. Student self-reports suggested cognitive gains from laboratory experience may be based in student initiated questioning during and after the laboratory experience. This is compatible with a constructivist explanation of student schema development.

  6. Hands-on Activities for Exploring the Solar System in K-14 Formal and Informal Education Settings

    NASA Astrophysics Data System (ADS)

    Allen, J. S.; Tobola, K. W.

    2004-12-01

    Introduction: Activities developed by NASA scientists and teachers focus on integrating Planetary Science activities with existing Earth science, math, and language arts curriculum. Educators may choose activities that fit a particular concept or theme within their curriculum from activities that highlight missions and research pertaining to exploring the solar system. Most of the activities use simple, inexpensive techniques that help students understand the how and why of what scientists are learning about comets, asteroids, meteorites, moons and planets. The web sites for the activities contain current information so students experience recent mission information such as data from Mars rovers or the status of Stardust sample return. The Johnson Space Center Astromaterials Research and Exploration Science education team has compiled a variety of NASA solar system activities to produce an annotated thematic syllabus useful to classroom educators and informal educators as they teach space science. An important aspect of the syllabus is that it highlights appropriate science content information and key science and math concepts so educators can easily identify activities that will enhance curriculum development. The outline contains URLs for the activities and NASA educator guides as well as links to NASA mission science and technology. In the informal setting, educators can use solar system exploration activities to reinforce learning in association with thematic displays, planetarium programs, youth group gatherings, or community events. In both the informal and the primary education levels the activities are appropriately designed to excite interest, arouse curiosity and easily take the participants from pre-awareness to the awareness stage. Middle school educators will find activities that enhance thematic science and encourage students to think about the scientific process of investigation. Some of the activities offered may easily be adapted for the upper levels of high school and early college, as they require students to use and analyze data. Syllabus Format: The Exploring the Solar System Syllabus of Activities starts with a variety of solar system scale activities that fit different settings and equipment. The early solar system formation activities are focused on asteroids, meteorites and planet formation. The theme of how and why we explore our solar system encompasses activities that engage the language and creative arts. Further activities highlight the Sun and planetary geology. A key aspect of the usefulness of the syllabus is that it provides easy access to solar system content, activities, related links and the thematic context for the classroom teacher or group leader. Conclusion: The Exploring the Solar System Syllabus of Activities is a concentrated resource of activities and links that allows educators to comfortably and inexpensively share the excitement and science of solar system exploration with students and members of the public. Additional Information: Some of the activities included in the Exploring the Solar System Syllabus of Activities are in the following NASA developed guides. http://ares.jsc.nasa.gov/Education/index.html

    Webb, Curtis M.; White, Steve; Rich, Brian

    2013-06-01

    Active Short Wave InfraRed (SWIR) imaging presents unique challenges to laboratory testing. It is always important to have laboratory testing that will directly relate to field performance. This paper will present the modeling and corresponding laboratory testing that was developed for these types of systems. The paper will present the modeling that was used to derive the lab metric used for verification testing of the system and provide details into the design of the lab equipment that was necessary to ensure accurate lab testing. The Noise Limited Resolution (NLR) test, first developed for low light imaging systems in the 1960s, serves as the basic lab metric for the evaluation of the active SWIR system. This test serves well for a quick test (go-no go) and is used to evaluate this system during production testing. The test derivation will be described and shown how it relates to the modeling results. The test equipment developed by Santa Barbara InfraRed (SBIR) for this application allows for accurate uniform radiance levels from an integrating sphere for both 1.06um and 1.57um imaging applications. The source has the ability to directly mimic any laser system and can provide pulsed laser source radiation from 20 nanoseconds to 500 nanoseconds resulting in levels from 0.4 to 85 nJ/cm2/sr, peak radiance levels. The light source can be triggered to replicate a laser return at any range from 100m to 100,000m. Additionally, the source provides the ability to output Mid Wave IR (MWIR) illumination through the use of a small extended area IR source in the integrating sphere. This is useful for boresighting the active SWIR sensor with other sensors such as Forward Looking IR (FLIR).

    Vrtacnik, Margareta; Gros, Natasa

    2013-01-01

    In this paper, the effect of introducing visible spectrometry concepts through hands-on laboratory work upon student learning within four vocational programs are discussed. All together, 118 students, average 18.6 years old, participated in the study. The results showed no correlation between students' motivational components (intrinsic, regulated, and controlled), chemistry self-concept and their achievement on an experiential knowledge test and knowledge gained from this hands-on approach. Statistically significant differences were found for academic achievement among students in a biotechnology technical program (School 1), food processing program (School 2), laboratory biomedicine program (School 3), and a biotechnology general program (School 4). Differences in academic achievement are further reflected in students' perception of particular knowledge gained through their hands-on experiences and in their expressed attitude toward different didactical characteristics. All students, regardless of their study program, highly evaluated the relaxed atmosphere that contributed to their self-confidence in completing their laboratory activities. PMID:23841355

  1. Hands-on physics displays for undergraduates

    NASA Astrophysics Data System (ADS)

    Akerlof, Carl W.

    2014-07-01

    Initiated by Frank Oppenheimer in 1969, the Exploratorium in San Francisco has been the model for hands-on science museums throughout the world. The key idea has been to bring people with all levels of scientific background in contact with interesting and attractive exhibits that require the active participation of the visitor. Unfortunately, many science museums are now forced to cater primarily to very young audiences, often 8 years old or less, with predictable constraints on the intellectual depth of their exhibits. To counter this trend, the author has constructed several hands-on displays for the University of Michigan Physics Department that demonstrate: (1) magnetic levitation of pyrolytic graphite, (2) the varied magnetic induction effects in aluminum, copper and air, (3) chaotic motion of a double pendulum, (4) conservation of energy and momentum in a steel ball magnetic accelerator, (5) the diffraction pattern of red and green laser pointer beams created by CDs and DVDs, (6) a magnetic analog of the refraction of light at a dielectric boundary and (7) optical rotation of light in an aqueous fructose solution. Each of these exhibits can be constructed for something like $1000 or less and are robust enough to withstand unsupervised public use. The dynamic behavior of these exhibits will be shown in accompanying video sequences. The following story has a history that goes back quite a few years. In the late 70's, I was spending time at the Stanford Linear Accelerator Center accompanied by my family that included our two grade school children. Needless to say, we much enjoyed weekend excursions to all sorts of interesting sites in the Bay Area, especially the Exploratorium, an unusual science museum created by Frank Oppenheimer that opened in 1969. The notion that exhibits would be designed specifically for "hands-on" interactions was at that time quite revolutionary. This idea captivated a number of people everywhere including a friend in Ann Arbor, Cynthia Yao. With a core group of a few dozen people, Cynthia convinced the City of Ann Arbor to allow free use of an old firehouse. The Ann Arbor Hands-On Museum opened its doors to the public in 1982 and remains a thriving institution to this day.

    2014-01-01

    This study includes the results of a 2-day education project titled "Molecular Biology Laboratory Summer School, MoBiLYO." The project was held at a University Research Center by scientists from Department of Pharmacology and graduate students. The project was composed of introductory lectures, model construction, DNA isolation, polymerase chain reaction (PCR), and gel electrophoresis. The participants were 13-year-old eighth-graders attending primary schools affiliated with Ministry of National Education in urban and rural areas of Izmir, Turkey. The purpose of this study was to introduce basic molecular biology concepts through individually performed experiments such as PCR and gel electrophoresis integrated with creative drama. The students were assessed at the beginning and the end of each project day via mini-tests, experimental and presentation skills evaluation forms. Data showed that students' knowledge about DNA structure and basic molecular biology techniques significantly increased. On the basis of experimental and presentational skills, there was no significant difference between kids from urban and rural schools or between public and boarding public schools, whereas the average score of girls was significantly higher than that of boys. In conclusion, individually performed experiments integrated with creative drama significantly increased students' perception of complex experimental procedures on basic molecular biology concepts. Data suggests that integration of these concepts into the science and technology curriculum of Turkish primary education may support the recruitment of future scientists who can handle rapidly developing genomic techniques that will affect our everyday life.

    Scharfenberg, Franz-Josef; Bogner, Franz X.

    2011-08-01

    Emphasis on improving higher level biology education continues. A new two-step approach to the experimental phases within an outreach gene technology lab, derived from cognitive load theory, is presented. We compared our approach using a quasi-experimental design with the conventional one-step mode. The difference consisted of additional focused discussions combined with students writing down their ideas (step one) prior to starting any experimental procedure (step two). We monitored students' activities during the experimental phases by continuously videotaping 20 work groups within each approach ( N = 131). Subsequent classification of students' activities yielded 10 categories (with well-fitting intra- and inter-observer scores with respect to reliability). Based on the students' individual time budgets, we evaluated students' roles during experimentation from their prevalent activities (by independently using two cluster analysis methods). Independently of the approach, two common clusters emerged, which we labeled as `all-rounders' and as `passive students', and two clusters specific to each approach: `observers' as well as `high-experimenters' were identified only within the one-step approach whereas under the two-step conditions `managers' and `scribes' were identified. Potential changes in group-leadership style during experimentation are discussed, and conclusions for optimizing science teaching are drawn.

    The US Department of Energy and its national laboratories are a major employer of scientists and engineers and consequently have a strong interest in the development and training of a qualified pool of employment candidates. For many years the DOE and its national laboratories have supported education activities devoted to increasing the number and quality of science and engineering graduates. This is part of the DOE mission because of the critical national need for scientists and engineers and the recognized deficiencies in the education system for science and mathematics training. Though funding support for such activities has waxed and waned, strong education programs have survived in spite of budget pressures. This paper reviews a few of the education programs presently supported at Sandia by the Science and Technology Outreach Department. The US DOE Defense Programs Office and Sandia National Laboratories provide financial support for these education activities.

    2005-03-01

    This paper will briefly outline major activities in Department of Energy (DOE) Laboratories focused on mobile platforms, both Unmanned Ground Vehicles (UGV’s) as well as Unmanned Air Vehicles (UAV’s). The activities will be discussed in the context of the science and technology construct used by the DOE Technology Roadmap for Robotics and Intelligent Machines (RIM)1 published in 1998; namely, Perception, Reasoning, Action, and Integration. The activities to be discussed span from research and development to deployment in field operations. The activities support customers in other agencies. The discussion of "perception" will include hyperspectral sensors, complex patterns discrimination, multisensor fusion and advances in LADAR technologies, including real-world perception. "Reasoning" activities to be covered include cooperative controls, distributed systems, ad-hoc networks, platform-centric intelligence, and adaptable communications. The paper will discuss "action" activities such as advanced mobility and various air and ground platforms. In the RIM construct, "integration" includes the Human-Machine Integration. Accordingly the paper will discuss adjustable autonomy and the collaboration of operator(s) with distributed UGV’s and UAV’s. Integration also refers to the applications of these technologies into systems to perform operations such as perimeter surveillance, large-area monitoring and reconnaissance. Unique facilities and test beds for advanced mobile systems will be described. Given that this paper is an overview, rather than delve into specific detail in these activities, other more exhaustive references and sources will be cited extensively.

    The use of renewable energy technologies is typically thought of as an integral part of creating and sustaining an environment that maximizes the overall quality of life of the Earth`s present inhabitants and does not leave an undue burden on future generations. Sandia National Laboratories has been a leader in developing and deploying many of these technologies over the last two decades. A common but special aspect of all of these activities is that they are all conducted in cooperation with various types of partners. Some of these partners have an interest in seeing these systems grow in the marketplace, while others are primarily concerned with economic benefits that can come from immediate use of these renewable energy systems. This paper describes solar thermal and photovoltaic technology activities at Sandia that are intended to accelerate the commercialization of these solar systems.

    2014-07-01

    A long-term exposition focused on optics and photonics was created in Institute of Atomic Physics and Spectroscopy at University of Latvia in 2010. Considering unpopularity of science in Latvia and lack of broadly accessible hands-on outreach activities for school children, as well as rapid development of advanced photonic technologies, this exposition was meant to involve more students to the natural sciences and modern technologies. Exposition covers 10 topics of optics - colors, diffraction, interference, polarization, reflection, liquid crystals, gas discharge, lasers, fluorescence, infrared and ultraviolet radiation. Students' visits are organized as an exciting adventure, which differs from ordinary school lessons. The visit mainly includes own actions with hands-on exhibits, lecturer's explanations about the most difficult topics and some demonstrations shown by the lecturer. The main accent is made on hands-on experiments due to the fact that students, who had performed hands-on experiments, will be emboldened to choose their career in the field of science and technologies. The exposition now is running and is part of Riga Photonics Center. Nearly 300 students from the 8th till 12th grades visited it during academic years 2011/2012 and 2012/2013 and their generally positive feedback has been analyzed.

    Allen, Mary E.; Gyure, Ruth A.

    2013-01-01

    Bacteriophage are among the most diverse and numerous microbes inhabiting our planet. Yet many laboratory activities fail to engage students in meaningful exploration of their diversity, unique characteristics, and abundance. In this curriculum activity students use a standard plaque assay to enumerate bacteriophage particles from a natural sample and use the scientific method to address questions about host specificity and diversity. A raw primary sewage sample is enriched for bacteriophage using hosts in the family Enterobacteriaceae. Students hypothesize about host specificity and use quantitative data (serial dilution and plaque assay) to test their hypotheses. Combined class data also help them answer questions about phage diversity. The exercise was field tested with a class of 47 students using pre- and posttests. For all learning outcomes posttest scores were higher than pretest scores at or below p = 0.01. Average individualized learning gain (G) was also calculated for each learning outcome. Students’ use of scientific language in reference to bacteriophage and host interaction significantly improved (p = 0.002; G = 0.50). Improved means of expression helped students construct better hypotheses on phage host specificity (G = 0.31, p = 0.01) and to explain the plaque assay method (G = 0.33, p = 0.002). At the end of the exercise students also demonstrated improved knowledge and understanding of phage specificity as related to phage therapy in humans (p < 0.001; G = 51). PMID:23858357

  5. Image Processing for Educators in Global Hands-On Universe

    NASA Astrophysics Data System (ADS)

    Miller, J. P.; Pennypacker, C. R.; White, G. L.

    2006-08-01

    A method of image processing to find time-varying objects is being developed for the National Virtual Observatory as part of Global Hands-On Universe(tm) (Lawrence Hall of Science; University of California, Berkeley). Objects that vary in space or time are of prime importance in modern astronomy and astrophysics. Such objects include active galactic nuclei, variable stars, supernovae, or moving objects across a field of view such as an asteroid, comet, or extrasolar planet transiting its parent star. The search for these objects is undertaken by acquiring an image of the region of the sky where they occur followed by a second image taken at a later time. Ideally, both images are taken with the same telescope using the same filter and charge-coupled device. The two images are aligned and subtracted with the subtracted image revealing any changes in light during the time period between the two images. We have used a method of Christophe Alard using the image processing software IDL Version 6.2 (Research Systems, Inc.) with the exception of the background correction, which is done on the two images prior to the subtraction. Testing has been extensive, using images provided by a number of National Virtual Observatory and collaborating projects. They include the Supernovae Trace Cosmic Expansion (Cerro Tololo Inter-American Observatory), Supernovae/ Acceleration Program (Lawrence Berkeley National Laboratory), Lowell Observatory Near-Earth Object Search (Lowell Observatory), and the Centre National de la Recherche Scientifique (Paris, France). Further testing has been done with students, including a May 2006 two week program at the Lawrence Berkeley National Laboratory. Students from Hardin-Simmons University (Abilene, TX) and Jackson State University (Jackson, MS) used the subtraction method to analyze images from the Cerro Tololo Inter-American Observatory (CTIO) searching for new asteroids and Kuiper Belt objects. In October 2006 students from five U.S. high schools will use the subtraction method in an asteroid search campaign using CTIO images with 7-day follow-up images to be provided by the Las Cumbres Observatory (Santa Barbara, CA). During the Spring 2006 semester, students from Cape Fear High School used the method to search for near-Earth objects and supernovae. Using images from the Astronomical Research Institute (Charleston, IL) the method contributed to the original discovery of two supernovae, SN 2006al and SN 2006bi.

    Melo, Murilo R; Clark, Samantha; Barrio, Daniel

    2011-04-01

    Clinical laboratories provide an invaluable service to millions of people around the world in the form of quality diagnostic care. Within the clinical laboratory industry the impetus for change has come from technological development (miniaturization, nanotechnology, and their collective effect on point-of-care testing; POCT) and the increasingly global nature of laboratory services. Potential technological gains in POCT include: the development of bio-sensors, microarrays, genetics and proteomics testing, and enhanced web connectivity. In globalization, prospective opportunities lie in: medical tourism, the migration of healthcare workers, cross-border delivery of testing, and the establishment of accredited laboratories in previously unexplored markets. Accompanying these impressive opportunities are equally imposing challenges. Difficulty transitioning from research to clinical use, poor infrastructure in developing countries, cultural differences and national barriers to global trade are only a few examples. Dealing with the issues presented by globalization and the impact of developing technology on POCT, and on the clinical laboratory services industry in general, will be a daunting task. Despite such concerns, with appropriate countermeasures it will be possible to address the challenges posed. Future laboratory success will be largely dependent on one's ability to adapt in this perpetually shifting landscape. PMID:21175379

  8. Hands-on lessons in ergonomics for youth

    2005-09-29

    Ergonomics risk factors apply to everybody. Numerous adults have experienced disabling injuries related to use of computers and other forms of technology. Now children are using technology even more than adults. Increasingly ergonomics risk factors are being recognized as present in the world of children. Outreach to schools and the surrounding community by employers may help protect the future work force. A growing body of researchers believe that children can benefit from the early introduction of ergonomics awareness and preventative measures. While individual representatives of the educational system may embrace the concept of introducing ergonomics into the classroom, a number of barriers can prevent implementation of integrated programs. Some of the barriers to introducing ergonomics in schools have been absence of a tie to educational standards, the existing demands on teaching hours, and the absence of easily executable lesson plans. Ergonomics is rarely included in teacher training and professional ergonomics expertise is needed for the development of a class-based program. As part of Strategic Vision plan for 2025, a National Laboratory identified community outreach and the future workforces as key areas for initiatives. A series of hands-on interactive modules have been developed by professional ergonomics specialists. They are being tested with elementary, middle and high school students. Where possible, the content has been tied to the educational standards in the State of California in the USA. Currently the modules include grip strength, effective breathing, optimal keyboard and mouse positions, optimizing chairs, posture and movement, backpack safety and safe lifting. Each module takes the students through a related activity or experience. An individual worksheet asks them questions about the experience and guides them to consider implications in their activities of daily living. A module on hearing is under development. The goal is to have a toolkit that teachers can use in classrooms with minimal training. The kit will come with lesson plans, including background material, key points, questions and answers, possible homework assignments and references. It will include instructions and worksheets for students as well as the materials needed for each module. A pre- and posttest will be administered to test the awareness and understanding of the principles introduced in through the modules. This interactive session will offer the opportunity to for attendees to participate in some of the modules that have been developed to provide experiential demonstration of ergonomics principles. Attendees will experience ergonomics in action and be able to evaluate the applicability of the process in their own area in the world of ergonomics. The session will consist of 20 minutes introduction, 40 minutes working with the toolkit, finally another 30 minutes for questions or discussion for a total time of 90 minutes.

    It is imperative to fascinate young children at an early stage in their education for the analytical sciences. The exposure of the public to mass spectrometry presently increases rapidly through the common media. Outreach activities can take advantage of this exposure and employ mass spectrometry as an exquisite example of an analytical science in which children can be fascinated. The presented teaching modules introduce children to mass spectrometry and give them the opportunity to experience a modern research laboratory. The modules are highly adaptable and can be applied to young children from the age of 6 to 14 y. In an interactive tour, the students explore three major scientific concepts related to mass spectrometry; the building blocks of matter, charged particle manipulation by electrostatic fields, and analyte identification by mass analysis. Also, the students carry out a mass spectrometry experiment and learn to interpret the resulting mass spectra. The multistage, inquiry-based tour contains flexible methods, which teach the students current-day research techniques and possible applications to real research topics. Besides the scientific concepts, laboratory safety and hygiene are stressed and the students are enthused for the analytical sciences by participating in "hands-on" work. The presented modules have repeatedly been successfully employed during laboratory open days. They are also found to be extremely suitable for (early) high school science classes during laboratory visit-focused field trips.

    2013-01-01

    The Association of Public Health Laboratories (APHL) and the APHL Laboratory Systems and Standards Committee manage the Laboratory System Improvement Program (L-SIP). One component of L-SIP is an assessment that allows the members and stakeholders of a laboratory system to have an open and honest discussion about the laboratory system's strengths and weaknesses. From these facilitated discussions, gaps and opportunities for improvement are identified. In some cases, ideas for how to best address these gaps emerge, and workgroups are formed. Depending on resources, both monetary and personnel, laboratory staff will then prioritize the next component of L-SIP: which quality improvement activities to undertake. This article describes a sample of quality improvement activities initiated by several public health laboratories after they conducted L-SIP assessments. These projects can result in more robust linkages between system entities, which can translate into improvements in the way the system addresses the needs of stakeholders. PMID:23997301

    1993-04-01

    In order to obtain comparability among laboratory results obtained by different laboratories, standardization is necessary in all steps related to clinical laboratory practice. Standardization in clinical laboratory is a consensus process among professional, industrial and governmental organizations. Everyone concerned in clinical laboratory practice should try to follow those consensus proposed. The International Organization for Standardization (ISO) is a key international body which is represented by many different national organizations. World Health Organization (WHO) plays an important role in medical field, but many non-governmental organizations (NGO) such as the World Association of Societies of Pathology (WASP), the International Federation for Clinical Chemistry (IFCC) and others also contribute significantly. In 1975, the National Committee for Clinical Laboratory Standards (NCCLS) was established in USA and has been the most active. In 1985, The Japanese Committee for Clinical Laboratory Standards (JCCLS) was established as some other CCLS in different European countries. National activity for establishing many reference materials in Japan is briefly reviewed. PMID:8350495

    Four simple experiments are described, in two laboratory sessions of 3 hours each. They provide high school students of a combined science course with the opportunity to review and integrate many topics while participating in a hands-on activity that resembles real industrial problems. The first lab comprises the calibration of a CO2 potentiometric detector with gas mixtures. The CO2 and CO2-free air required for the gaseous samples are produced in the lab by an inexpensive and simple apparatus. In the second lab, the CO2 potentiometric device is used to measure CO2uptake and release during different metabolic processes. The variation of CO2 production will be also estimated while changing the air/fuel proportion in a Bunsen burner.

  17. Teachers' Perspectives on Online Virtual Labs vs. Hands-On Labs in High School Science

    NASA Astrophysics Data System (ADS)

    Bohr, Teresa M.

    This study of online science teachers' opinions addressed the use of virtual labs in online courses. A growing number of schools use virtual labs that must meet mandated laboratory standards to ensure they provide learning experiences comparable to hands-on labs, which are an integral part of science curricula. The purpose of this qualitative case study was to examine teachers' perceptions of the quality and effectiveness of high school virtual labs. The theoretical foundation was constructivism, as labs provide student-centered activities for problem solving, inquiry, and exploration of phenomena. The research questions focused on experienced teachers' perceptions of the quality of virtual vs. hands-on labs. Data were collected through survey questions derived from the lab objectives of The Next Generation Science Standards . Eighteen teachers rated the degree of importance of each objective and also rated how they felt virtual labs met these objectives; these ratings were reported using descriptive statistics. Responses to open-ended questions were few and served to illustrate the numerical results. Many teachers stated that virtual labs are valuable supplements but could not completely replace hands-on experiences. Studies on the quality and effectiveness of high school virtual labs are limited despite widespread use. Comprehensive studies will ensure that online students have equal access to quality labs. School districts need to define lab requirements, and colleges need to specify the lab experience they require. This study has potential to inspire positive social change by assisting science educators, including those in the local school district, in evaluating and selecting courseware designed to promote higher order thinking skills, real-world problem solving, and development of strong inquiry skills, thereby improving science instruction for all high school students.

    NASA Astrophysics Data System (ADS)

    Oien, R. P.; Anders, A. M.; Long, A.

    2014-12-01

    We present the initial results of transitioning laboratory activities in an introductory physical geology course from passive to active learning. Educational research demonstrates that student-driven investigations promote increased engagement and better retention of material. Surveys of students in introductory physical geology helped us identify lab activities which do not engage students. We designed new lab activities to be more collaborative, open-ended and "hands-on". Student feedback was most negative for lab activities which are computer-based. In response, we have removed computers from the lab space and increased the length and number of activities involving physical manipulation of samples and models. These changes required investment in lab equipment and supplies. New lab activities also include student-driven exploration of data with open-ended responses. Student-evaluations of the new lab activities will be compiled during Fall 2014 and Spring 2015 to allow us to measure the impact of the changes on student satisfaction and we will report on our findings to date. Modification of this course has been sponsored by NSF's Widening Implementation & Demonstration of Evidence Based Reforms (WIDER) program through grant #1347722 to the University of Illinois. The overall goal of the grant is to increase retention and satisfaction of STEM students in introductory courses.

HOU curricula should be published within a year, and we are developing HOU Centers across America and the World, to be on-going and self-sustained sites for teachers to learn how to teach and undertake astronomy in their classrooms. HOU is currently developing museum kiosks for image acquisition and processing in science centers, using an on site robotic telescope, and 0.35 meter telescopes around the world in real time. Over 700 teachers around the United States and another 700 teachers from around the world have taken HOU workshops, and about 2/3 use it in their classrooms. A particularly important development is the HOU collaboration with Johns Hopkins University as part of the usage of National Virtual Observatory and SDSS images and data for education. Such data systems are beginning to result in a flood of data, which will soon overwhelm students and teachers, unless we prepare for this onslaught carefully. HOU has met resonance with other astronomers and educators around the world. Global HOU is thriving, and next years Global HOU meeting will be held at NAOC in Beijing, China.

    2009-06-01

    For long time optics' scientists all around the world realised the importance to the development of optics of providing our school students a good effective education in optics. A large range of quality educational support materials was developed and is readily available. Fortunately this is also true in what concerns materials to be used in hands-on experiments based learning covering virtually all fields of optics and also intended or adapted for use at all school levels. Recent trends in educational policies are given science education an increasing importance within school' curricula. Furthers efforts must be developed in order to increase the importance of optics in school syllabus and generalize it throughout all school levels, while guaranteeing a quality effective education. This demands a strong focus on an active investigative hands-on experiments based study of the different subjects of light and optics by the students at the classroom in formal context but also in different informal activities. In this process the role of the teacher is of crucial importance. Quite often, however, teachers are not adequately trained in this type of pedagogic approach and frequently feel the need of further training in these issues but also on the recent advances of optics and photonics. In other to tackle this need a number of different training courses for school teachers, from pre-school to highschool and vocational training schools, were designed and will be presented and discussed in this communication.

    Typically, introductory physics courses are taught with a combination of lectures and laboratories in which students have opportunities to discover the natural laws through hands-on activities in small groups. This article reports the use of Google Drive, a free online document-sharing tool, in physics laboratories for pooling experimental data from the whole class. This pedagogical method was reported earlier, and the present article offers a few more examples of such "whole class" laboratories.

    2007-09-01

    The project is collaboration between two scientific societies, the Optical Society of America (OSA) and SPIE - The International Society for Optical Engineering and the National Optical Astronomy Observatory (NOAO). The program is designed to bring science education enrichment to thousands of underrepresented middle school students in more than ten states, including female and minority students, who typically have not been the beneficiaries of science and engineering resources and investments. HOO provides each teacher with up to six activity modules, each containing enough materials for up to 30 students to participate in 6-8 hours of hands-on optics-related activities. Sample activities, developed by education specialists at NOAO, include building kaleidoscopes and telescopes, communicating with a beam of light, and a hit-the-target laser beam challenge. Teachers engage in two days of training and, where possible, are partnered with a local optics professional (drawn from the local rosters of SPIE and OSA members) who volunteers to spend time with the teacher and students as they explore the module activities. Through these activities, students gain experience and understanding of optics principles, as well as learning the basics of inquiry, critical thinking, and problem solving skills involving optics, and how optics interfaces with other disciplines. While the modules were designed for use in informal after- school or weekend sessions, the number of venues has expanded to large and small science centers, Boys and Girls Clubs, Girl Scouts, summer camps, family workshops, and use in the classroom.

  19. Hands-on-Entropy, Energy Balance with Biological Relevance

    NASA Astrophysics Data System (ADS)

    Reeves, Mark

    2015-03-01

    Entropy changes underlie the physics that dominates biological interactions. Indeed, introductory biology courses often begin with an exploration of the qualities of water that are important to living systems. However, one idea that is not explicitly addressed in most introductory physics or biology textbooks is important contribution of the entropy in driving fundamental biological processes towards equilibrium. From diffusion to cell-membrane formation, to electrostatic binding in protein folding, to the functioning of nerve cells, entropic effects often act to counterbalance deterministic forces such as electrostatic attraction and in so doing, allow for effective molecular signaling. A small group of biology, biophysics and computer science faculty have worked together for the past five years to develop curricular modules (based on SCALEUP pedagogy). This has enabled students to create models of stochastic and deterministic processes. Our students are first-year engineering and science students in the calculus-based physics course and they are not expected to know biology beyond the high-school level. In our class, they learn to reduce complex biological processes and structures in order model them mathematically to account for both deterministic and probabilistic processes. The students test these models in simulations and in laboratory experiments that are biologically relevant such as diffusion, ionic transport, and ligand-receptor binding. Moreover, the students confront random forces and traditional forces in problems, simulations, and in laboratory exploration throughout the year-long course as they move from traditional kinematics through thermodynamics to electrostatic interactions. This talk will present a number of these exercises, with particular focus on the hands-on experiments done by the students, and will give examples of the tangible material that our students work with throughout the two-semester sequence of their course on introductory physics with a bio focus.

    2013-01-01

    Undergraduate research can make a positive impact on science education. Unfortunately, the one student-one mentor paradigm of undergraduate research generates a wide range of variability in the student’s experience and further limits its availability to a select few students. In contrast, a single faculty member can offer multiple undergraduate teaching positions that provide a consistent experience for the student. We attempted to combine the undergraduate research and teaching experiences in an internship practicum called Peer Instruction and Laboratory Occupational Training (PILOT). Students enrolled in PILOT served as teaching assistants for the upper division Quantitative Biological Methods (QBM) laboratory course. In addition, PILOT students worked on an independent lab project that provided them with hands-on training and supported the QBM course. The development of presentation and teaching skills was also emphasized in PILOT. These activities were designed to improve student communication skills, lab skills, and knowledge of molecular biology content. Here, we describe the PILOT curriculum and report the results of an anonymous assessment survey administered to 75 students who had completed PILOT in the previous five semesters. Our data indicate that PILOT provides an effective format to expand undergraduate opportunities for research and teaching experiences. PMID:23858352

    By the time students are ready to enter the workforce they have been exposed to up to 20 years of ergonomics risk factors. As technology evolves, it provides more opportunities for intensive repetitive motion and with computers, cell phones, personal digital assistants (PDAs), and electronic games. The average student engages in fewer active physical activities, sit stationary in mismatched furniture in schools for hours and carry heavy backpacks. While long-term effects remain to be identified, increasingly ergonomists and others concerned with musculoskeletal health and wellness, see a need for early ergonomics education. This interactive session provides a hands-on approach to introducing ergonomics to students. Although different approaches may effectively introduce ergonomics at even early stages of development, this program was designed for youth at the middle to high school age. Attendees will participate in four activities designed to introduce ergonomics at an experiential level. The modules focus on grip strength, effective breathing, optimizing your chair, and backpack safety. The workshop will include presentation and worksheets designed for use by teachers with minimal ergonomics training. Feedback from the participants will be sought for further refining the usability and safety of the training package.

    2015-04-01

    The present study reports the elaboration, application and evaluation of a problem-based learning (PBL) program that aims to evaluate the effectiveness in students learning the Rock Cycle theme. Prior research on both PBL and Rock Cycle was conducted within the context of science education so as to elaborate and construct the intervention program. Findings from these studies indicated both the PBL methodology and Rock Cycle as helpful for teachers and students. PBL methodology has been adopted in this study since it is logically incorporated in a constructivism philosophy application and it was expected that this approach would assist students towards achieving a specific set of competencies. PBL is a student-centered method based on the principle of using problems as the starting point for the acquisition of new knowledge. Problems are based on complex real-world situations. All information needed to solve the problem is initially not given. Students will identify, find, and use appropriate resources to complete the exercise. They work permanently in small groups, developing self-directed activities and increasing participation in discussions. Teacher based guidance allows students to be fully engaged in knowledge building. That way, the learning process is active, integrated, cumulative, and connected. Theme "Rock Cycle" was introduced using a problematic situation, which outlined the geological processes highlighted in "Foz do Douro" the next coastline of the school where the study was developed. The questions proposed by the students were solved, using strategies that involved the use of hands-on activities and virtual labs in Geology. The systematization of the selected theme was performed in a field excursion, implemented according to the organizational model of Nir Orion, to The "Foz do Douro" metamorphic complex. In the evaluation of the learning process, data were obtained on students' development of knowledge and competencies through the application of several instruments such as small questionnaires (Hot Potatoes), Gowin V, scientific report, a grid to evaluate group work and a grid to evaluate the development of competencies. This study intended to evaluate the success of a PBL intervention program when trying to improve students' outcomes. The positive impact obtained allowed us to advance some conclusions and instructional implications regarding teaching Rock Cycle through PBL and different digital and hands-on resources, obtained, especially in the students' questionnaires and Gowin V, allowed us to verify that students did learn about Rock Cycle and developed collaborative work skills.

    Since the appearance in 1986 of epidemic of bovine spongiform encephalopathy (BSE), a new form of neurological disease in cattle which also affected human beings, many diagnostic and research activities have been performed to develop detection and therapeutic tools. A lot of progress was made in better identifying, understanding and controlling the spread of the disease by appropriate monitoring and control programs in European countries. This paper reviews the recent knowledge on pathogenesis, transmission and persistence outside the host of prion, the causative agent of transmissible spongiform encephalopathies (TSE) in mammals with a particular focus on risk (re)assessment and management of biosafety measures to be implemented in diagnostic and research laboratories in Belgium. Also, in response to the need of an increasing number of European diagnostic laboratories stopping TSE diagnosis due to a decreasing number of TSE cases reported in the last years, decontamination procedures and a protocol for decommissioning TSE diagnostic laboratories is proposed.

    We have developed a hands-on, experimental module that combines biology experiments with a physics-based analytical model to characterize antimicrobial compounds. To understand antibiotic resistance, participants perform a disc diffusion assay to test the antimicrobial activity of different compounds, then apply a diffusion-based analytical model to gain insights into the behavior of the active antimicrobial component. In our experience, this module was robust, reproducible, and cost-effective, suggesting that it could be implemented in diverse settings such as undergraduate research, STEM camps, school programs, and laboratory training workshops. This module addresses the paucity of structured training or education programs that integrate diverse scientific fields by providing valuable, interdisciplinary research experience in science outreach and education initiatives. Its low cost requirements make it especially suitable for use in resource-limited settings.

  20. Argonne National Laboratory annual report of Laboratory Directed Research and Development Program Activities FY 2009.

    SciTech Connect

    Office of the Director

    2010-04-09

    I am pleased to submit Argonne National Laboratory's Annual Report on its Laboratory Directed Research and Development (LDRD) activities for fiscal year 2009. Fiscal year 2009 saw a heightened focus by DOE and the nation on the need to develop new sources of energy. Argonne scientists are investigating many different sources of energy, including nuclear, solar, and biofuels, as well as ways to store, use, and transmit energy more safely, cleanly, and efficiently. DOE selected Argonne as the site for two new Energy Frontier Research Centers (EFRCs) - the Institute for Atom-Efficient Chemical Transformations and the Center for Electrical Energy Storage - and funded two other EFRCs to which Argonne is a major partner. The award of at least two of the EFRCs can be directly linked to early LDRD-funded efforts. LDRD has historically seeded important programs and facilities at the lab. Two of these facilities, the Advanced Photon Source and the Center for Nanoscale Materials, are now vital contributors to today's LDRD Program. New and enhanced capabilities, many of which relied on LDRD in their early stages, now help the laboratory pursue its evolving strategic goals. LDRD has, since its inception, been an invaluable resource for positioning the Laboratory to anticipate, and thus be prepared to contribute to, the future science and technology needs of DOE and the nation. During times of change, LDRD becomes all the more vital for facilitating the necessary adjustments while maintaining and enhancing the capabilities of our staff and facilities. Although I am new to the role of Laboratory Director, my immediate prior service as Deputy Laboratory Director for Programs afforded me continuous involvement in the LDRD program and its management. Therefore, I can attest that Argonne's program adhered closely to the requirements of DOE Order 413.2b and associated guidelines governing LDRD. Our LDRD program management continually strives to be more efficient. In addition to meeting all reporting requirements during fiscal year 2009, our LDRD Office continues to enhance its electronic systems to streamline the LDRD management process. You will see from the following individual project reports that Argonne's researchers have once again done a superb job pursuing projects at the forefront of their respective fields and have contributed significantly to the advancement of Argonne's strategic thrusts. This work has not only attracted follow-on sponsorship in many cases, but is also proving to be a valuable basis upon which to continue realignment of our strategic portfolio to better match the Laboratory's Strategic Plan.

    2009-04-01

    Brookhaven National Laboratory (BNL) is a multidisciplinary laboratory that maintains a primary mission focus the physical sciences, energy sciences, and life sciences, with additional expertise in environmental sciences, energy technologies, and national security. It is managed by Brookhaven Science Associates, LLC, (BSA) under contract with the U. S. Department of Energy (DOE). BNL's Fiscal year 2008 budget was $531.6 million. There are about 2,800 employees, and another 4,300 guest scientists and students who come each year to use the Laboratory's facilities and work with the staff. The BNL Laboratory Directed Research and Development (LDRD) Program reports its status to the U.S. Department of Energy (DOE) annually in March, as required by DOE Order 413.2B, 'Laboratory Directed Research and Development,' April 19, 2006, and the Roles, Responsibilities, and Guidelines for Laboratory Directed Research and Developlnent at the Department of Energy/National Nuclear Security Administration Laboratories dated June 13, 2006. Accordingly, this is our Annual Report in which we describe the Purpose, Approach, Technical Progress and Results, and Specific Accomplishments of all LDRD projects that received funding during Fiscal Year 2008. BNL expended $12 million during Fiscal Year 2008 in support of 69 projects. The program has two categories, the annual Open Call LDRDs and Strategic LDRDs, which combine to meet the overall objectives of the LDRD Program. Proposals are solicited annually for review and approval concurrent with the next fiscal year, October 1. For the open call for proposals, an LDRD Selection Committee, comprised of the Associate Laboratory Directors (ALDs) for the Scientific Directorates, an equal number of scientists recommended by the Brookhaven Council, plus the Assistant Laboratory Director for Policy and Strategic Planning, review the proposals submitted in response to the solicitation. The Open Can LDRD category emphasizes innovative research concepts with limited management filtering to encourage the creativity of individual researchers. The competition is open to all BNL staff in programmatic, scientific, engineering, and technical support areas. Researchers submit their project proposals to the Assistant Laboratory Director for Policy and Strategic Planning. A portion of the LDRD budget is held for the Strategic LDRD (S-LDRD) category. Projects in this category focus on innovative R&D activities that support the strategic agenda of the Laboratory. The Laboratory Director entertains requests or articulates the need for S-LDRD funds at any time. Strategic LDRD Proposals also undergo rigorous peer review; the approach to review is tailored to the size and scope of the proposal. These Projects are driven by special opportunities, including: (1) Research project(s) in support of Laboratory strategic initiatives as defined and articulated by the Director; (2) Research project(s) in support of a Laboratory strategic hire; (3) Evolution of Program Development activities into research and development activities; and (4) ALD proposal(s) to the Director to support unique research opportunities. The goals and objectives of BNL's LDRD Program can be inferred fronl the Program's stated purposes. These are to (1) encourage and support the development of new ideas and technology, (2) promote the early exploration and exploitation of creative and innovative concepts, and (3) develop new 'fundable' R&D projects and programs. The emphasis is clearly articulated by BNL to be on supporting exploratory research 'which could lead to new programs, projects, and directions' for the Laboratory. We explicitly indicate that research conducted under the LDRD Program should be highly innovative, and an element of high risk as to success is acceptable. To be one of the premier DOE National Laboratories, BNL must continuously foster groundbreaking scientific research. At Brookhaven National Laboratory one such method is through its LDRD Program. This discretionary research and development tool is critical in maintaining the scientific excellence and long-term vitality of the Laboratory. Additionally, it is a means to stimulate the scientific community and foster new science and technology ideas, which becomes a major factor in achieving and maintaining staff excellence and a means to address National needs within the overall mission of the DOE and BNL.

    NASA Astrophysics Data System (ADS)

    Moin, Laura J.

    Previous research in science education has provided evidence that textbook-oriented instruction falls short of achieving desired educational outcomes. In the 1960s, educational reform movements advocated involving students in laboratory experiments with the belief that such hands-on tasks would necessarily lead to learning. In the mid-1980s, the introduction of computers in education provided an alternative to hands-on instruction, but comparisons between hands-on (HO) and computer-mediation (CM) have been scarce and contradictory. Recently, researchers have speculated about the potential benefits of HO versus CM instruction for individuals of different abilities; but few empirical studies have addressed this issue. This research compares immediate and delayed achievement (measured as concept understanding, problem solving, and total learning) and conversations of small groups of students (blocked as high, medium, and low achievers) under each condition. Statistical analysis (2 x 3 randomized block design, Two-Way ANOVA: Instruction method x Prior achievement level) revealed a disordinal interaction between treatment and achievement level: computer instruction resulted in more learning gains for low achievers and hands-on instruction was more effective for high achievers. Hands-on students struggled with procedural demands and obtained less accurate experimental results, making data more difficult to interpret. In contrast, for high achievers, unreliable experimental results seemed to have engendered more discussion among peers and elicited more explanations, which likely led to greater learning gains. In the computer condition, students were relieved of the manipulative demands of real objects, which helped low achievers concentrate on the conceptual aspects of the lesson. The computer facilitated completion of the "experiments" more quickly and hence allowed low achieving students more time to engage with practice tasks, an activity closely monitored and supported by the classroom teacher. My findings have important implications in science education. First, there is no method that works best for all students. Second, these findings may assist the design of school support and gifted programs.

    The Systems Analysis Programs for Hands-on Integrated Reliability Evaluations (SAPHIRE) is a software application developed for performing a complete probabilistic risk assessment (PRA) using a personal computer running the Microsoft Windows? operating system. SAPHIRE is primarily funded by the U.S. Nuclear Regulatory Commission (NRC) and developed by the Idaho National Laboratory (INL). The INL's primary role in this project is that of software developer and tester. Using the SAPHIRE analysis engine and relational database is a complementary program called GEM. GEM has been designed to simplify using existing PRA analysis for activities such as the NRC’s Accident Sequence Precursor program. In this report, the theoretical framework behind GEM-type calculations are discussed in addition to providing guidance and examples for performing evaluations when using the GEM software. As part of this analysis framework, the two types of GEM analysis are outlined, specifically initiating event (where an initiator occurs) and condition (where a component is failed for some length of time) assessments.

    SciTech Connect

    FOX,K.J.

    2002-12-31

    Brookhaven National (BNL) Laboratory is a multidisciplinary laboratory that carries out basic and applied research in the physical, biomedical, and environmental sciences, and in selected energy technologies. It is managed by Brookhaven Science Associates, LLC, under contract with the U. S. Department of Energy. BNL's total annual budget has averaged about $450 million. There are about 3,000 employees, and another 4,500 guest scientists and students who come each year to use the Laboratory's facilities and work with the staff. The BNL Laboratory Directed Research and Development (LDRD) Program reports its status to the U.S. Department of Energy (DOE) annually in March, as required by DOE Order 4 1 3.2A, ''Laboratory Directed Research and Development,'' January 8, 2001, and the LDRD Annual Report guidance, updated February 12, 1999. The LDRD Program obtains its funds through the Laboratory overhead pool and operates under the authority of DOE Order 413.2A. The goals and objectives of BNL's LDRD Program can be inferred from the Program's stated purposes. These are to (1) encourage and support the development of new ideas and technology, (2) promote the early exploration and exploitation of creative and innovative concepts, and (3) develop new ''fundable'' R&D projects and programs. The emphasis is clearly articulated by BNL to be on supporting exploratory research ''which could lead to new programs, projects, and directions'' for the Laboratory. As one of the premier scientific laboratories of the DOE, BNL must continuously foster groundbreaking scientific research. At Brookhaven National Laboratory one such method is through its LDRD Program. This discretionary research and development tool is critical in maintaining the scientific excellence and long-term vitality of the Laboratory. Additionally, it is a means to stimulate the scientific community and foster new science and technology ideas, which becomes a major factor in achieving and maintaining staff excellence and a means to address national needs within the overall mission of the DOE and BNL. The LDRD Annual Report contains summaries of all research activities funded during Fiscal Year 2002. The Project Summaries with their accomplishments described in this report reflect the above. Aside from leading to new fundable or promising programs and producing especially noteworthy research, the LDRD activities have resulted in numerous publications in various professional and scientific journals and presentations at meetings and forums. All Fy 2002 projects are listed and tabulated in the Project Funding Table. Also included in this Annual Report in Appendix A is a summary of the proposed projects for FY 2003. The BNL LDRD budget authority by DOE in FY 2002 was $7 million. The actual allocation totaled $6.7 million. The following sections in this report contain the management processes, peer review, and the portfolio's relatedness to BNL's mission, initiatives and strategic plans. Also included is a metric of success indicators.

    Johansson, K. E.

    With the Hands on CERN project it is possible to ``take part'' in a modern particle physics experiment at the forefront of scientific research using scientific data transmitted via Internet. The primary aim is to show particle collisions from the physics frontline, to stimulate the interest in science and technology and to demonstrate the openness and international character of fundamental research. Hands on CERN complements the traditional physics education and confronts the students with contemporary physics and technology - both detector technology and data transmission technology via Internet - at its most fundamental level.

  16. Hands-on Space Exploration through High Altitude Ballooning

    NASA Astrophysics Data System (ADS)

    Hammergren, Mark; Gyuk, G.

    2010-01-01

    The Adler Planetarium's "Far Horizons" high-altitude ballooning effort serves as the focus for a diverse set of educational activities, including middle school summer camps, a high school summer program (the Astro-Science Workshop), school-year internships for high school students, summer internships for undergraduates, a NSF-funded graduate fellowship, and a thriving public volunteer program. The relatively low costs of both the reusable hardware (less than $1000) and expendable supplies (around $150 per launch) allow us to mount frequent missions throughout the year - and make such a program ideal for replication at institutions of any size. The rapid development schedule for each individual mission permits the cradle-to-grave involvement of short-term participants, making it easy to draw in a wide audience. Students are involved literally in a hands-on manner in all aspects of the construction, launch, tracking, and recovery of simple experimental payloads, which typically include sensors for temperature, pressure, light intensity, and radiation. Stunning imagery provided by onboard cameras can attract significant media interest, which can bring outreach efforts to a very broad audience. Future plans include the design and construction of CubeSats - decimeter-sized picosatellites carried to orbit as secondary payloads. Our first satellite will be a relatively simple Earth-imager, built from commercial, off-the-shelf components. As in the ballooning program, students and volunteers will be involved in all stages of this effort. Once operational, imagery and other data from the satellite will be incorporated into a museum exhibit that will allow visitors to submit target requests. This material is based in part upon work supported by the National Science Foundation under Grant No. 0525995.

    SciTech Connect

    Quist, A.S.

    2001-01-30

    The facilities that became Oak Ridge National Laboratory (ORNL) were created in 1943 during the United States' super-secret World War II project to construct an atomic bomb (the Manhattan Project). During World War II and for several years thereafter, essentially all ORNL activities were classified. Now, in 2000, essentially all ORNL activities are unclassified. The major purpose of this report is to provide a brief history of ORNL's major classified activities from 1943 until the present (September 2000). This report is expected to be useful to the ORNL Classification Officer and to ORNL's Authorized Derivative Classifiers and Authorized Derivative Declassifiers in their classification review of ORNL documents, especially those documents that date from the 1940s and 1950s.

    PubMed

    Dietz, V; Vugia, D; Nelson, R; Wicklund, J; Nadle, J; McCombs, K G; Reddy, S

    2000-03-01

    Cryptosporidium parvum leaped to the attention of the United States following the 1993 outbreak in Milwaukee, Wisconsin, which sickened 400,000 people. Other outbreaks in the United States have been associated with drinking and recreational water, consumption of contaminated foods, contact with animals, and childcare attendance. Despite its public health importance, the number of people who become infected each year is not known. In 1997, active surveillance for C. parvum was added to the Foodborne Diseases Active Surveillance Network (FoodNet), a collaborative effort among the Centers for Disease Control and Prevention, selected state health departments, the U.S. Departments of Agriculture and Food and Drug Administration. During the first 2 years of surveillance, 1,023 laboratory-confirmed cases of cryptosporidiosis were detected in FoodNet (Connecticut, Minnesota, Oregon, and selected counties in California, Georgia, Maryland, and New York). The annual rate per 100,000 persons was 2.3. Sixteen percent of case-patients were hospitalized. A seasonal increase in case detection was noted in late summer among persons less than 15 years of age. These data represent the first active multistate ascertainment of laboratory-confirmed cryptosporidiosis cases and provide useful information on the burden of disease in the United States.

  12. Increasing Awareness about Antibiotic Use and Resistance: A Hands-On Project for High School Students

    PubMed Central

    Fonseca, Maria João; Santos, Catarina L.; Costa, Patrício; Lencastre, Leonor; Tavares, Fernando

    2012-01-01

    Background Health-promoting education is essential to foster an informed society able to make decisions about socio-scientific issues based on scientifically sustained criteria. Antibiotic resistance is currently a major public health issue. Considering that irrational antibiotic use has been associated with the development and widespread of antibiotic resistant bacteria, educational interventions to promote prudent antibiotic consumption are required. Methodology/Principal Findings This study focuses on the outcomes of an interventional program implemented at the University of Porto, Portugal, to promote awareness about antibiotic resistance at high school levels (15‚Äď17 year old). The project Microbiology recipes: antibiotics √† la carte articulates a set of wet and dry lab activities designed to promote the participants‚Äô understanding of concepts and processes underlying antibiotics‚Äô production and activity, such as the notion of mechanisms of action of antibiotics. Following a mix-method approach based on a pre‚ąí/post design, the effectiveness of this project was assessed by gathering data from surveys, direct observation and analysis of artifacts of 42 high school students (aged 15 and 16 years). The results indicate that the participants developed a more comprehensive picture of antibiotic resistance. The project was shown to promote more sophisticated conceptualizations of bacteria and antibiotics, increased awareness about the perils of antibiotic resistance, and enhanced consciousness towards measures that can be undertaken to mitigate the problem. The participants regarded their experiences as enjoyable and useful, and believed that the project contributed to improve their understanding and raise their interest about the issues discussed. Furthermore, there were also improvements in their procedural skills concerning the laboratory techniques performed. Conclusions/Significance This study evidences the possibility of increasing high school students‚Äô awareness about the consequences of antibiotic resistance and the importance of judicious antibiotic use. The findings inform about the educational benefits of incorporating hands-on activities in science education programs. PMID:22984544

    2009-06-01

    A new laboratory has been commissioned at Idaho National Laboratory for performing active neutron interrogation research and development. The facility is designed to provide radiation shielding for deuterium-tritium (DT) fusion (14.1 MeV) neutron generators (2 x 10(8) n/s), deuterium-deuterium (DD) fusion (2.5 MeV) neutron generators (1 x 10(7) n/s), and (252)Cf spontaneous fission neutron sources (6.96 x 10(7) n/s, 30 microg). Shielding at the laboratory is comprised of modular concrete shield blocks 0.76 m thick with tongue-in-groove features to prevent radiation streaming, arranged into one small and one large test vault. The larger vault is designed to allow operation of the DT generator and has walls 3.8m tall, an entrance maze, and a fully integrated electrical interlock system; the smaller test vault is designed for (252)Cf and DD neutron sources and has walls 1.9 m tall and a simple entrance maze. Both analytical calculations and numerical simulations were used in the design process for the building to assess the performance of the shielding walls and to ensure external dose rates are within required facility limits. Dose rate contour plots have been generated for the facility to visualize the effectiveness of the shield walls and entrance mazes and to illustrate the spatial profile of the radiation dose field above the facility and the effects of skyshine around the vaults.

  14. Teaching genetics using hands-on models, problem solving, and inquiry-based methods

    NASA Astrophysics Data System (ADS)

    Hoppe, Stephanie Ann

    Teaching genetics can be challenging because of the difficulty of the content and misconceptions students might hold. This thesis focused on using hands-on model activities, problem solving, and inquiry-based teaching/learning methods in order to increase student understanding in an introductory biology class in the area of genetics. Various activities using these three methods were implemented into the classes to address any misconceptions and increase student learning of the difficult concepts. The activities that were implemented were shown to be successful based on pre-post assessment score comparison. The students were assessed on the subjects of inheritance patterns, meiosis, and protein synthesis and demonstrated growth in all of the areas. It was found that hands-on models, problem solving, and inquiry-based activities were more successful in learning concepts in genetics and the students were more engaged than tradition styles of lecture.

The ultimate goal of the program is the development of state of the art technologies which characterize geothermal reservoirs and evaluate their productive capacity and longevity.

  16. Invention activities as preparation for learning laboratory data handling skills

    NASA Astrophysics Data System (ADS)

    Day, James

    2012-10-01

    Undergraduate physics laboratories are often driven by a mix of goals, and usually enough of them to cause cognitive overload for the student. Our recent findings align well with studies indicating that students often exit a physics lab without having properly learned how to handle real data. The value of having students explore the underlying structure of a problem before being able to solve it has been shown as an effective way to ready students for learning. Borrowing on findings from the fields of education and cognitive psychology, we use ``invention activities'' to precede direct instruction and bolster learning. In this talk I will show some of what we have learned about students' data handling skills, explain how an invention activity works, and share some observations of successful transfer.

  17. In vivo neutron activation facility at Brookhaven National Laboratory

    1997-11-01

    Seven important body elements, C, N, Ca, P, K, Na, and Cl, can be measured with great precision and accuracy in the in vivo neutron activation facilities at Brookhaven National Laboratory. The facilities include the delayed-gamma neutron activation, the prompt-gamma neutron activation, and the inelastic neutron scattering systems. In conjunction with measurements of total body water by the tritiated-water dilution method several body compartments can be defined from the contents of these elements, also with high precision. In particular, body fat mass is derived from total body carbon together with total body calcium and nitrogen; body protein mass is derived from total body nitrogen; extracellular fluid volume is derived from total body sodium and chlorine; lean body mass and body cell mass are derived from total body potassium; and, skeletal mass is derived from total body calcium. Thus, we suggest that neutron activation analysis may be valuable for calibrating some of the instruments routinely used in clinical studies of body composition. The instruments that would benefit from absolute calibration against neutron activation analysis are bioelectric impedance analysis, infrared interactance, transmission ultrasound, and dual energy x-ray/photon absorptiometry.

    MSLICE (Mars Science Laboratory InterfaCE) is the tool used by scientists and engineers on the Mars Science Laboratory rover mission to visualize the data returned by the rover and collaboratively plan its activities. It enables users to efficiently and effectively search all mission data to find applicable products (e.g., images, targets, activity plans, sequences, etc.), view and plan the traverse of the rover in HiRISE (High Resolution Imaging Science Experiment) images, visualize data acquired by the rover, and develop, model, and validate the activities the rover will perform. MSLICE enables users to securely contribute to the mission s activity planning process from their home institutions using off-the-shelf laptop computers. This software has made use of several plug-ins (software components) developed for previous missions [e.g., Mars Exploration Rover (MER), Phoenix Mars Lander (PHX)] and other technology tasks. It has a simple, intuitive, and powerful search capability. For any given mission, there is a huge amount of data and associated metadata that is generated. To help users sort through this information, MSLICE s search interface is provided in a similar fashion as major Internet search engines. With regard to the HiRISE visualization of the rover s traverse, this view is a map of the mission that allows scientists to easily gauge where the rover has been and where it is likely to go. The map also provides the ability to correct or adjust the known position of the rover through the overlaying of images acquired from the rover on top of the HiRISE image. A user can then correct the rover s position by collocating the visible features in the overlays with the same features in the underlying HiRISE image. MSLICE users can also rapidly search all mission data for images that contain a point specified by the user in another image or panoramic mosaic. MSLICE allows the creation of targets, which provides a way for scientists to collaboratively name features on the surface of Mars. These targets can also be used to convey instrument-pointing information to the activity plan. The software allows users to develop a plan of what they would like the rover to accomplish for a given time period. When developing the plan, the user can input constraints between activities or groups of activities. MSLICE will enforce said constraints and ensure that all mission flight rules are satisfied.

  20. Back to the future with hands-on science: students' perceptions of learning anatomy and physiology.

    This article examines student perceptions of learning related to anatomy and physiology in a bachelor of nursing program. One strategy to teach the sciences is simulated learning, a technology that offers exciting potential. Virtual environments for laboratory learning may offer numerous benefits: teachers can convey information to a larger group of students, reducing the need for small laboratory classes; less equipment is required, thus containing ongoing costs; and students can learn in their own time and place. However, simulated learning may also diminish access to the teacher-student relationship and the opportunity for guided practice and guided linking of theory with practice. Without this hands-on experience, there is a risk that students will not engage as effectively, and thus conceptual learning and the development of critical thinking skills are diminished. However, student perceptions of these learning experiences are largely unknown. Thus, this study examined students' perceptions of anatomy and physiology laboratory experiences and the importance they placed on hands-on experience in laboratory settings. PMID:18792709

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

    The Integrated Ocean Drilling Program (IODP) - United States Implementing Organization (USIO) took advantage of a 16-day break between scientific operations to carry out a seagoing pilot educator workshop on board the JOIDES Resolution during a transit from Victoria, B.C., Canada, to Acapulco, Mexico. During this workshop, 10 educators from all across the United States were mentored and taught by scientists who are actively engaged in IODP research, the USIO Education Director, and staff. In addition, shipboard technical staff provided guidance and content related to hands-on laboratory activities. The pilot program provided the educators with an opportunity to participate in a seagoing experience on a scientific drilling research vessel and conduct a series of research activities similar to those that take place during regular scientific drilling expeditions. The workshop allowed educators to increase their knowledge of IODP and scientific methods as borne out through ocean drilling (proposals, drilling, lab analysis, data acquisition, postcruise activities) as well as knowledge of mid-ocean ridges, composition and structure of the oceanic crust, seafloor spreading, paleoceanography, paleomagnetism, and sedimentology. The workshop participants translated the scientific results into useful teaching resources by developing a suite of new discovery-based activities related to ocean drilling research that will undergo classroom testing by workshop participants. Over the school year the educators will help disseminate IODP science education by conducting at least two teacher workshops based on this seagoing experience, enhanced scientific knowledge gained from participating in the workshop, and the new activities developed en route.

    A force spectroscopy model experiment is presented using a low-cost tensile apparatus described earlier. Force-extension measurements of twisted rubber bands are obtained. They exhibit a complex nonlinear elastic behaviour that resembles atomic force spectroscopy investigations of molecules of titin, a muscle protein. The model experiments open up intriguing possibilities to stimulate insight into entropy-driven self-organization of soft biological matter at the nanometre scale and into protein folding by hands-on experience and analogical transfer.

    The Nuclear Engineering Teaching Laboratory (NETL) at the University of Texas at Austin performs a wide variety of educational activities for students at various levels. Regular on-site courses in the areas of health physics, radiochemistry, and reactor operations are offered for university credit. Along with on-site courses, access to the reactor facility via a remote console connection allows students in an off-site classroom to conduct experiments via a "virtual" control console. In addition to the regularly scheduled courses, other programs, such as the Nuclear Regulatory Commission Summer Nuclear Engineering Institute and Office of Naval Research partnerships with Historically Black Colleges and Universities, provide access to the facility for students from other universities both domestic and foreign. And NETL hosts professional development programs such as training programs for Nuclear Regulatory Commission personnel and International Atomic Energy Agency fellowships.

    Vision and Change [AAAS, 2011] outlines a blueprint for modernizing biology education by addressing conceptual understanding of key concepts, such as the relationship between structure and function. The document also highlights skills necessary for student success in 21st century Biology, such as the use of modeling and simulation. Here we describe a laboratory activity that allows students to investigate the dynamic nature of protein structure and function through the use of a modeling technique known as molecular dynamics (MD). The activity takes place over two lab periods that are 3 hr each. The first lab period unpacks the basic approach behind MD simulations, beginning with the kinematic equations that all bioscience students learn in an introductory physics course. During this period students are taught rudimentary programming skills in Python while guided through simple modeling exercises that lead up to the simulation of the motion of a single atom. In the second lab period students extend concepts learned in the first period to develop skills in the use of expert MD software. Here students simulate and analyze changes in protein conformation resulting from temperature change, solvation, and phosphorylation. The article will describe how these activities can be carried out using free software packages, including Abalone and VMD/NAMD. © 2016 by The International Union of Biochemistry and Molecular Biology, 44:130-139, 2016.

    2005-01-01

    The future of aviation propulsion systems is increasingly focused on the application of control technologies to significantly enhance the performance of a new generation of air vehicles. Active flow control refers to a set of technologies that manipulate the flow of air and combustion gases deep within the confines of an engine to dynamically alter its performance during flight. By employing active flow control, designers can create engines that are significantly lighter, are more fuel efficient, and produce lower emissions. In addition, the operating range of an engine can be extended, yielding safer transportation systems. The realization of these future propulsion systems requires the collaborative development of many base technologies to achieve intelligent, embedded control at the engine locations where it will be most effective. NASA Glenn Research Center s Controls and Dynamics Technology Branch has developed a state-of-the-art low-speed Active Flow Control Laboratory in which emerging technologies can be integrated and explored in a flexible, low-cost environment. The facility allows the most promising developments to be prescreened and optimized before being tested on higher fidelity platforms, thereby reducing the cost of experimentation and improving research effectiveness.

    For the past several years, we have been exploring the use of computers and the results of physics education research in teaching introductory physics to our engineering and science students at North Carolina State University. Students have the opportunity to learn physics using Socratic dialogs, self-directed computer simulations, peer-teaching in collaborative homework groups, and hands-on experimentation. New textbooks, Excel spreadsheet exercises, and laboratory practicums provide new directions for teaching standard courses. An overview of some of these experiences will be given along with an assessment of future implementations into other sections taught by different faculty members.

  13. Teaching radio astrophysics the hand-on way

    NASA Astrophysics Data System (ADS)

    Joshi, Bhal Chandra

    Astronomy and space sciences have always been instrumental in attracting young students to physical sciences. While the lectures/demonstrations and exhibitions pertaining to space sci-ences capture the imagination of young students, these alone are not sufficient to induce them to join scientific research. In countries like India, where a large number of students take to physical sciences for under-graduate education, complex sociological factors are key issues in translating this large body of students to potential researchers. While lectures and exhibition lead to an increase in scientific awareness for these students, these do not give a feel for scien-tific research and bridge the gap between high school/college science education and high end research. In this context, a hands-on approach to astronomy education, in science research environments or closely connected to scientific institutions, offers a promising alternative. This approach has been used in optical astronomy, where inexpensive small telescopes are available, often coupling a vast network of amateur astronomy clubs to leading astronomy institutes. The non-visual and relatively more technical nature of radio astronomy has limited a similar approach in past for connecting students to space sciences using radio waveband. The tech-nological explosion in communication industry and radio connectivity in the last decade along with an expansion in engineering education makes this possible now using a hands-on approach in teaching radio astrophysics. In this presentation, the sociological factors affecting the student choice are discussed followed by a review of the efforts to bridge the above mentioned gap by various groups in the world in the last decade with a view to enumerate the best practices in a hands-on approach. A program using this approach at National Center for Radio Astrophysics is described, where the students are exposed to simple hands-on radio astronomy experiments such as spectral line observations of neutral hydrogen from Milky Way and solar flux moni-toring. Such experiments are also useful to familiarize the students with astronomy jargon, which many times becomes an impediment in connecting them with research. This program also aims to develop low cost radio telescopes with involvement of engineering students and the presentation aims at sharing the experience in this program. Future possibilities bridging the gap between the research institutions, such as ours, and the student population at large are also discussed.

  14. An investigation of the impact of selected prereading activities on student content learning through laboratory activities

    NASA Astrophysics Data System (ADS)

    Kass, Jesse (Shaya)

    This study investigated whether two prereading activities impacted student learning from hands-on science activities. The study was based on constructivist learning theory. Based on the work of Piaget, it was hypothesized that students who activated prior knowledge would learn more from the activities. Based on the work of Vygotsky it was hypothesized that students who talk more and write more would learn more from the activity. The K-W-L chart and anticipation guide strategies were used with eighth grade students at Graves Middle School in Whittier, California before learning about levers and convection currents. D. M. Ogle (1986) created the three-column K-W-L chart to have students activate prior knowledge. In the first column, the students write what they already know about a subject, in the second column, the students write what they want to know about the subject, and the students complete the third column after learning about a subject by writing answers to the questions that they asked in the second column. Duffelmeyer (1994) created the anticipation guide based on Herber's (1978) reasoning guide. In the anticipation guide, the teacher creates three or four sentences that convey the major ideas of the topic and the students either agree or disagree with the statements. After learning about the topic, students revisit their answers and decide if they were correct or incorrect and they must defend their choices. This research used the Solomon (1947) four-square design and compared both the experimental groups to a control group that simply discussed the concepts before completing the activity. The research showed no significant difference between the control group and either of the treatment groups. The reasons for the lack of significant differences are considered. It was hypothesized that since the students were unfamiliar with the prereading activities and did not have much experience with using either writing-to-learn or talking-to-learn strategies, the short-term intervention was not effective. Directions for future study are considered.

    Most physics professors would agree that the lab experiences students have in introductory physics are central to the learning of the concepts in the course. It is also true that these physics labs require time and money for upkeep, not to mention the hours spent setting up and taking down labs. Virtual physics lab experiences can provide an alternative or supplement to these traditional hands-on labs. However, physics professors may be very hesitant to give up the hands-on labs, which have been such a central part of their courses, for a more cost and time-saving virtual alternative. Thus, it is important to investigate how the learning from these virtual experiences compares to that acquired through a hands-on experience. This study evaluated a comprehensive set of virtual labs for introductory level college physics courses and compared them to a hands-on physics lab experience. Each of the virtual labs contains everything a student needs to conduct a physics laboratory experiment, including: objectives, background theory, 3D simulation, brief video, data collection tools, pre- and postlab questions, and postlab quiz. This research was conducted with 224 students from two large universities and investigated the learning that occurred with students using the virtual labs either in a lab setting or as a supplement to hands-on labs versus a control group of students using the traditional hands-on labs only. Findings from both university settings showed the virtual labs to be as effective as the traditional hands-on physics labs.

    The performance of a novel "hands-on" robotic system for total knee replacement (TKR) surgery is evaluated. An integrated robotic system for accurately machining the bone surfaces in TKR surgery is described. Details of the system, comprising an "active constraint" robot, called Acrobot, a "gross positioning" robot, and patient clamps, are provided. The intraoperative protocol and the preoperative, CT-based, planning system are also described. A number of anatomical registration and cutting trials, using plastic bones, are described, followed by results from two preliminary clinical trials, which demonstrate the accuracy achieved in the anatomical registration. Finally, the first clinical trial is described, in which the results of the anatomical registration and bone cutting are seen to be of high quality. The Acrobot system has been successfully used to accurately register and cut the knee bones in TKR surgery. This demonstrates the great potential of a "hands-on" robot for improving accuracy and increasing safety in surgery. PMID:11954064

    2012-11-01

    Problem-based learning has been demonstrated as an effective methodology for developing analytical skills and critical thinking. The use of scenario-based learning incorporates problem-based learning whilst encouraging students to collaborate with their colleagues and dynamically adapt to their environment. This increased interaction stimulates a deeper understanding and the generation of new knowledge. The Victorian Space Science Education Centre (VSSEC) uses scenario-based learning in its Mission to Mars, Mission to the Orbiting Space Laboratory and Primary Expedition to the M.A.R.S. Base programs. These programs utilize methodologies such as hands-on applications, immersive-learning, integrated technologies, critical thinking and mentoring to engage students in Science, Technology, Engineering and Mathematics (STEM) and highlight potential career paths in science and engineering. The immersive nature of the programs demands specialist environments such as a simulated Mars environment, Mission Control and Space Laboratory, thus restricting these programs to a physical location and limiting student access to the programs. To move beyond these limitations, VSSEC worked with its university partners to develop a web-based mission that delivered the benefits of scenario-based learning within a school environment. The Robotic Mission to Mars allows students to remotely control a real rover, developed by the Australian Centre for Field Robotics (ACFR), on the VSSEC Mars surface. After completing a pre-mission training program and site selection activity, students take on the roles of scientists and engineers in Mission Control to complete a mission and collect data for further analysis. Mission Control is established using software developed by the ACRI Games Technology Lab at La Trobe University using the principles of serious gaming. The software allows students to control the rover, monitor its systems and collect scientific data for analysis. This program encourages students to work scientifically and explores the interaction between scientists and engineers. This paper presents the development of the program, including the involvement of university students in the development of the rover, the software, and the collation of the scientific data. It also presents the results of the trial phase of this program including the impact on student engagement and learning outcomes.

    Hands-On Optics (HOO) is a collaborative four-year program to create and sustain a unique, national, informal science education program to excite students about science by actively engaging them in optics activities. The standards based activities and demonstrations have been successfully used in a variety of settings including formal classrooms, after school clubs, and science centers. One of the themes for the International Year of Astronomy (IYA) is "Looking Through a Telescope". We intend to use HOO activities in conjunction with the IYA to reinforce this important area. In this workshop, participants completed a series of activities involving refraction, lenses, telescopes, and ultraviolet light and took home a kit containing all the materials required to do the activities with a small group of students. Participants explored the basic properties of positive lenses to create images through the use of hands-on activities, exciting experiments, and educator-lead demonstrations, culminating with the building of a small refracting telescope. Several prototype telescopes were examined in the workshop for use in the International Year of Astronomy.

    2003-09-01

    Over the past ten years, Sandia has developed RF radar responsive tag systems and supporting technologies for various government agencies and industry partners. RF tags can function as RF transmitters or radar transponders that enable tagging, tracking, and location determination functions. Expertise in tag architecture, microwave and radar design, signal analysis and processing techniques, digital design, modeling and simulation, and testing have been directly applicable to these tag programs. In general, the radar responsive tag designs have emphasized low power, small package size, and the ability to be detected by the radar at long ranges. Recently, there has been an interest in using radar responsive tags for Blue Force tracking and Combat ID (CID). The main reason for this interest is to allow airborne surveillance radars to easily distinguish U.S. assets from those of opposing forces. A Blue Force tracking capability would add materially to situational awareness. Combat ID is also an issue, as evidenced by the fact that approximately one-quarter of all U.S. casualties in the Gulf War took the form of ground troops killed by friendly fire. Because the evolution of warfare in the intervening decade has made asymmetric warfare the norm rather than the exception, swarming engagements in which U.S. forces will be freely intermixed with opposing forces is a situation that must be anticipated. Increasing utilization of precision munitions can be expected to drive fires progressively closer to engaged allied troops at times when visual de-confliction is not an option. In view of these trends, it becomes increasingly important that U.S. ground forces have a widely proliferated all-weather radar responsive tag that communicates to all-weather surveillance. The purpose of this paper is to provide an overview of the recent, current, and future radar responsive research and development activities at Sandia National Laboratories that support both the Blue Force Tracking and Combat ID application.

    Transitioning to a new discipline can be challenging because of the need to quickly assimilate new skills and knowledge that others brought up in the field took years to develop. While reading and taking classes help to add knowledge, hands-on experience is key to developing your new skill set. Fieldwork is one obvious way to gain experience. Fieldwork provides intimate knowledge of your new found discipline, which is one component of your skill set. However, fieldwork is normally for a short period of time and very focused, which does not quickly provide the second component of your skill set, that is, insight into how your discipline fits in the big picture of solving problems. Academic workshops and internships can help provide the additional experience to bring any young researcher into this higher level of understanding. As a specific example, I'll talk about a summer workshop I recently attended called CIDER (Cooperative Institute for Dynamic Earth Research), which is open for students to apply for every year. This workshop provided the opportunity to learn a working knowledge of other disciplines in geology, and helped to expand my view of geophysics' place in solving real problems. The workshop is a month long, the first two weeks of which were lectures and tutorials of every discipline represented. The second two weeks consisted of new research on projects that were proposed by the attendees. The attendees select which of those projects to participate in, and join a team to work vigorously for two weeks. Teams may continue work after the CIDER workshop for presentations at AGU (as in my case) and has potential for publication later. Why this workshop succeeds in advancing young researchers' understanding is that different disciplines work side by side on their research project. Students need to be made aware of this workshop, and other workshops and internships like it, to provide this added hands-on experience.

    Brookhaven National Laboratory (BNL) is a multidisciplinary laboratory that carries out basic and applied research in the physical, biomedical, and environmental sciences, and in selected energy technologies. It is managed by Brookhaven Science Associates, LLC, (BSA) under contract with the U. S. Department of Energy (DOE). BNL's Fiscal year 2007 budget was $515 million. There are about 2,600 employees, and another 4,500 guest scientists and students who come each year to use the Laboratory's facilities and work with the staff. The BNL Laboratory Directed Research and Development (LDRD) Program reports its status to the U.S. Department of Energy (DOE) annually in March, as required by DOE Order 413.2B, 'Laboratory Directed Research and Development', April 19, 2006, and the Roles, Responsibilities, and Guidelines for Laboratory Directed Research and Development at the Department of Energy/National Nuclear Security Administration Laboratories dated June 13, 2006. In accordance this is our Annual Report in which we describe the Purpose, Approach, Technical Progress and Results, and Specific Accomplishments of all LDRD projects that received funding during Fiscal Year 2007. The goals and objectives of BNL's LDRD Program can be inferred from the Program's stated purposes. These are to (1) encourage and support the development of new ideas and technology, (2) promote the early exploration and exploitation of creative and innovative concepts, and (3) develop new 'fundable' R&D projects and programs. The emphasis is clearly articulated by BNL to be on supporting exploratory research 'which could lead to new programs, projects, and directions' for the Laboratory. We explicitly indicate that research conducted under the LDRD Program should be highly innovative, and an element of high risk as to success is acceptable. In the solicitation for new proposals for Fiscal Year 2007 we especially requested innovative new projects in support of RHIC and the Light Source and any of the Strategic Initiatives listed at the LDRD web site. These included support for NSLS-II, RHIC evolving to a quantum chromo dynamics (QCD) lab, nanoscience, translational and biomedical neuroimaging, energy and, computational sciences. As one of the premier scientific laboratories of the DOE, BNL must continuously foster groundbreaking scientific research. At Brookhaven National Laboratory one such method is through its LDRD Program. This discretionary research and development tool is critical in maintaining the scientific excellence and long-term vitality of the Laboratory. Additionally, it is a means to stimulate the scientific community and foster new science and technology ideas, which becomes a major factor in achieving and maintaining staff excellence and a means to address national needs within the overall mission of the DOE and BNL.

    Hands-On Optics (HOO) is a collaborative four-year program to create and sustain a unique, national, informal science education program to excite students about science by actively engaging them in optics activities. It will reach underrepresented middle school students in after-school programs and at hands-on science centers nationwide. Project partners with NOAO are SPIE-The International Society for Optical Engineering, the Optical Society of America (OSA), and the Mathematics, Engineering, Science Achievement Program (MESA) of California. This program builds on the 2001 National Science Foundation planning grant (number ESI-0136024), Optics Education - A Blueprint for the 21st Century, undertaken to address the disconnect between the ubiquity of optics in everyday life and the noticeable absence of optics education in K-12 curricula and in informal science education. NOAO - with expertise in teaching optics, developing optics kits, and in science-educator partnerships is designing the HOO instructional materials by adapting well-tested formal education activities on light, color, and optical technology for the informal setting. These hands-on, high-interest, standards-connected activities and materials serve as the basis for 6, three-hour-long optics activity modules that will be used in informal education programs at 23 HOO host sites. NOAO also will train the educators, parents, and optics professionals who will work in teams to lead the HOO activities. A key component of the project will be the optics professionals from the two optical societies who currently are engaged in outreach activities and programs. Optics professionals will serve as resource agents teamed with science center and MESA educators, a model very successfully used by the Astronomical Society of the Pacific's Project ASTRO. The six modules and associated challenges and contests address reflection from one or many mirrors, image formation, colors and polarization, ultraviolet and infrared phenomena, and communication over a beam of light. Challenges and contests have also been created to augment the six modules. The Hands On Optics Project is funded by the National Science Foundation ISE program. NOAO is operated by the Association of Universities for Research in Astronomy (AURA), Inc. under cooperative agreement with the National Science Foundation.

    Recent carbon dioxide (CO2) remote sensing missions have set precision targets as demanding as 0.25% (1 ppm) in order to elucidate carbon sources and sinks [1]. These ambitious measurement targets will require the most precise body of spectroscopic reference data ever assembled. Active sensing missions will be especially susceptible to subtle line shape effects as the narrow bandwidth of these measurements will greatly limit the number of spectral transitions which are employed in retrievals. In order to assist these remote sensing missions we have employed frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) [2], a high-resolution, ultrasensitive laboratory technique, to measure precise line shape parameters for transitions of O2, CO2, and other atmospherically-relevant species within the near-infrared. These measurements have led to new HITRAN-style line lists for both 16O2 [3] and rare isotopologue [4] transitions in the A-band. In addition, we have performed detailed line shape studies of CO2 transitions near 1.6 őľm under a variety of broadening conditions [5]. We will address recent measurements in these bands as well as highlight recent instrumental improvements to the FS-CRDS spectrometer. These improvements include the use of the Pound-Drever-Hall locking scheme, a high bandwidth servo which enables measurements to be made at rates greater than 10 kHz [6]. In addition, an optical frequency comb will be utilized as a frequency reference, which should allow for transition frequencies to be measured with uncertainties below 10 kHz (3√ó10-7 cm-1). [1] C.

  11. Development of a Hands-On Survey Course in the Physics of Living Systems

    NASA Astrophysics Data System (ADS)

    Matthews, Megan; Goldman, Daniel I.

    Due to the widespread availability and technological capabilities of modern smartphones, many biophysical systems can be investigated using easily accessible, low-cost, and/or ``homemade'' equipment. Our survey course is structured to provide students with an overview of research in the physics of living systems, emphasizing the interplay between measurement, mechanism, and modeling required to understand principles at the intersection of physics and biology. The course proceeds through seven modules each consisting of one week of lectures and one week of hands-on experiments, called ``microlabs''. Using smartphones, Arduinos, and 3D printed materials students create their own laboratory equipment, including a 150X van Leeuwenhoek microscope, a shaking incubator, and an oscilloscope, and then use them to study biological systems ranging in length scales from nanometers to meters. These systems include population dynamics of rotifer/algae cultures, experimental evolution of multicellularity in budding yeast, and the bio- & neuromechanics involved in animal locomotion, among others. In each module, students are introduced to fundamental biological and physical concepts as well as theoretical and computational tools (nonlinear dynamics, molecular dynamics simulation, and statistical mechanics). At the end of the course, students apply these concepts and tools to the creation of their own microlab that integrates hands-on experimentation and modeling in the study of their chosen biophysical system.

    2014-12-01

    This presentation provides an overview of a hands-on modeling tool developed for students in civil engineering and earth science disciplines to help them learn the fundamentals of hydrologic processes, model calibration, sensitivity analysis, uncertainty assessment, and practice conceptual thinking in solving engineering problems. The toolbox includes two simplified hydrologic models, namely HBV-EDU and HBV-Ensemble, designed as a complement to theoretical hydrology lectures. The models provide an interdisciplinary application-oriented learning environment that introduces the hydrologic phenomena through the use of a simplified conceptual hydrologic model. The toolbox can be used for in-class lab practices and homework assignments, and assessment of students' understanding of hydrological processes. Using this modeling toolbox, students can gain more insights into how hydrological processes (e.g., precipitation, snowmelt and snow accumulation, soil moisture, evapotranspiration and runoff generation) are interconnected. The educational toolbox includes a MATLAB Graphical User Interface (GUI) and an ensemble simulation scheme that can be used for teaching more advanced topics including uncertainty analysis, and ensemble simulation. Both models have been administered in a class for both in-class instruction and a final project, and students submitted their feedback about the toolbox. The results indicate that this educational software had a positive impact on students understanding and knowledge of hydrology.

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

    NASA Astrophysics Data System (ADS)

    Miller, Donna Kaye Green

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

  16. Teaching Challenge in Hands-on DSP Experiments for Night-School Students

    NASA Astrophysics Data System (ADS)

    Wu, Hsien-Tsai; Kuo, Sen M.

    2008-12-01

    The rapid increase in digital signal processing (DSP) applications has generated a strong demand for electrical engineers with DSP backgrounds; however, the gap between industry needs and university curricula still exists. To answer this challenge, a sequence of innovative DSP courses that emphasize hands-on experiments and practical applications were developed for continuing education in electrical and computer engineering. These courses are taught in the evening for night-school students having at least three years of work experience. These courses enable students to experiment with sophisticated DSP applications to augment the theoretical, conceptual, and analytical materials provided in traditional DSP courses. The inclusion of both software and hardware developments allows students to undertake a wide range of DSP projects for real-world applications. Assessment data concludes that the digital signal processor fundamentals course can increase learning interest and overcome the prerequisite problem of DSP laboratory experiments. This paper also briefly introduces representative examples of some challenging DSP applications.

    The Sasakawa International Center for Space Architecture (SICSA) has a long history of projects that involve the design of space structures, including habitats for low-Earth orbit (LEO) and planetary applications. Some of these projects are supported by corporate sponsors, such as a space tourism research, planning and design study conducted for the owner of national U.S. hotel chain. Some have been undertaken in support of programs sponsored by the State Government of Texas, including current commercial spaceport development planning for the Texas Aerospace Commission and three counties that represent candidate spaceport sites. Other projects have been supported by NASA and the Texas Aerospace Consortium, including the design and development of SICSA's "Space Habitation Laboratory", a space station module sized environmental simulator facility which has been featured in the "NASA Select" television broadcast series. This presentation will highlight representative projects. SICSA is internationally recognized for its leadership in the field of space architecture. Many program graduates have embarked upon productive and rewarding careers with aerospace organizations throughout the world. NASA has awarded certificates of appreciation to SICSA for significant achievements contributing to its advanced design initiatives. SICSA and its work have been featured in numerous popular magazines, professional publications, and public media broadcasts in many countries. SICSA applies a very comprehensive scope of activities to the practice of space architecture. Important roles include mission planning conceptualization of orbital and planetary structures and assembly processes, and design of habitats to optimize human safety, adaptation and productivity. SICSA sponsors educational programs for upper division undergraduate students and graduate students with interests in space and experimental architecture. Many fourth year participants continue in the SICSA program throughout their remaining undergraduate studies, and are joined by other new fifth year students. Selected graduate applicants holding a professional degree in architecture from accredited colleges and universities can earn a Master of Architecture degree with a specialization in space and experimental architecture upon completion of 32 credit hours of study which includes two six-hour design studios. Accepted graduate students seeking a Master of Architecture degree who do not hold a professional architecture degree may enter SICSA studios during the final year of their minimum 72 credit hours of study. Subject to necessary University of Houston and Texas Higher Education Coordinating Board approvals, SICSA and the College of Architecture propose to expand their graduate education role to add a Master of Science in Space Architecture degree program. This new program is primarily being planned in response to known interests of non-architect professionals from NASA and aerospace corporations who wish to pursue advanced space architecture research and design studies. The program will be also available to working professionals holding an undergraduate architectural degree.

    In Brookhaven National Laboratory (BNL), we have been developing laser ion sources for diverse accelerators. Tabletop Nd:YAG lasers with up to several Joules of energy are mainly used to create ablation plasmas for stable operations.

    In Brookhaven National Laboratory (BNL), we have been developing laser ion sources for diverse accelerators. Tabletop Nd:YAG lasers with up to several Joules of energy are mainly used to create ablation plasmas for stable operations. The obtained charge states depend on laser power density and target species. Two types of ion extraction schemes, Direct Plasma Injection Scheme (DPIS) and conventional static extraction, are used depending on application. We optimized and select a suitable laser irradiation condition and a beam extraction scheme to meet the requirement of the following accelerator system. We have demonstrated to accelerate more than 5 x 1010 of C6+ ions using the DPIS. We successfully commissioned low charge ion beam provider to the user facilities in BNL.

    Brookhaven National Laboratory has for many years conducted examinations related to the failures of nuclear materials and components. These examinations included the confirmation of root cause analyses, the determination of the causes of failure, identification of the species that accelerate corrosion, and comparison of the results of nondestructive examinations with those obtained by destructive examination. The results of those examinations, which had previously appeared in various formats (formal and informal reports, journal articles, etc.), have been collected together and summarized in the present report. The report is divided into sections according to the general subject matter (for example, corrosion, fatigue, etc.). Each section presents summaries of the information contained in specific reports and publications, all of which are fully identified as to title, authors, report number or journal reference, date of publication, and FIN number under which the work was performed.

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

    Wiggins, Felita

    Student achievement in the Twenty First Century demands a new rigor in student science knowledge, since advances in science and technology require students to think and act like scientists. As a result, students must acquire proficient levels of knowledge and skills to support a knowledge base that is expanding exponentially with new scientific advances. This study examined the effects of hands-on-science instruction on the science achievement of middle school students. More specifically, this study was concerned with the influence of hands-on science instruction versus traditional science instruction on the science test scores of middle school students. The subjects in this study were one hundred and twenty sixth-grade students in six classes. Instruction involved lecture/discussion and hands-on activities carried out for a three week period. Specifically, the study ascertained the influence of the variables gender, ethnicity, and socioeconomic status on the science test scores of middle school students. Additionally, this study assessed the effect of the variables gender, ethnicity, and socioeconomic status on the attitudes of sixth grade students toward science. The two instruments used to collect data for this study were the Prentice Hall unit ecosystem test and the Scientific Work Experience Programs for Teachers Study (SWEPT) student's attitude survey. Moreover, the data for the study was treated using the One-Way Analysis of Covariance and the One-Way Analysis of Variance. The following findings were made based on the results: (1) A statistically significant difference existed in the science performance of middle school students exposed to hands-on science instruction. These students had significantly higher scores than the science performance of middle school students exposed to traditional instruction. (2) A statistically significant difference did not exist between the science scores of male and female middle school students. (3) A statistically significant difference did not exist between the science scores of African American and non-African American middle school students. (4) A statistically significant difference existed in the socioeconomic status of students who were not provided with assisted lunches. Students with unassisted lunches had significantly higher science scores than those middle school students who were provided with assisted lunches. (5) A statistically significant difference was not found in the attitude scores of middle school students who were exposed to hands-on or traditional science instruction. (6) A statistically significant difference was not found in the observed attitude scores of middle school students who were exposed to either hands-on or traditional science instruction by their socioeconomic status. (7) A statistically significant difference was not found in the observed attitude scores of male and female students. (8) A statistically significant difference was not found in the observed attitude scores of African American and non African American students.

    Experiments in a 2D static tank (dimensions 145 cm x 85 cm x 6 cm) were performed to assess the effectiveness of various geo-electrical methods (induced polarization [IP], resistivity [R], self potential [SP], electrodic potential [El]) to monitor microbial activity. The tank was filled with coarse sand and saturated with water from the river Lagan (Belfast, UK) diluted with tap water (20:80 ratio). The river water was used to 'seed' microbial activity in the tank. We created 2 separate zones of activity by applying a layer of Hydrogen Release Compound (HRC) and a layer of Oxygen Release Compound (ORC) at the bottom and the middle of the tank respectively. This design aimed to simulate conditions at the oxic - anoxic interface commonly found in contaminated groundwaters. We recorded IP and R signals using a network of 32 electrodes on one side of the tank; the same electrodes were used for El measurements; we recorded the SP signals with 9 Petiau electrodes located at the top of the tank. El measurements provide us with detailed information on the spatial and temporal Eh evolution in the tank, as a result of microbial activity (indirect evidence), whereas the SP measurements are related directly to the microbial activity (direct evidence); IP and R measurements were aimed to provide additional insight on microbial induced fluid conductivity / porosity / mineralization processes expected to occur under our experimental conditions. The combination of El and SP measurements is shown to be a powerful approach for remote monitoring of microbial activity in the subsurface; the methods supplement each other to more accurately describe the microbial evolution. Furthermore , the interpretation of the subsurface conditions are improved when constrained by the fluid conductivity and mineralization changes inferred by the IP and R measurements. The results of this work suggest that a combination of different geo-electrical methods enhance the subsurface monitoring of microbial activity.

    Two major legacies of the 4th International Polar Year (IPY 2007-9) are a newly galvanized educational community and an immense volume of polar data collected by the global science community. The tremendous new polar datasets represent a unique opportunity to communicate the nature of the changing poles to student and public audiences through this polar savvy educational community if effective approaches to link data and understanding are employed. We have developed a strategy for polar education that leverages the IPY data resources, linked with the polar education hands-on ‚Äėmanipulatives‚Äô (materials that students can manipulate in a dynamic manner). This linked approach leverages the fundamental inquiry based learning but recognizes that particularly in the polar sciences the size of the earth, the remoteness of the poles and the scale of its processes make it difficult for students to explore in a hands-on manner. The linking of polar hands-on ‚Äėmanipulatives‚Äô with IPY data provides a bridge between the tangible and the global. Alone manipulative activities can be beneficial in their ability to help students visualize a process or behavior, but without a strong link back to the Earth through data or evidence the understanding of the process is not transferred from the classroom model to the full scale Earth. The use of activities or models is beneficial in connecting the learner to the polar process(es), while the IPY data provides a unique opportunity to ground the polar manipulative experiments in real data. This linked strategy emerged from a series of NSF sponsored IPY Polar Fairs at major science museums that reached in excess of 12,000 people. The design of the fairs was that polar scientists developed activities linking low cost hands-on manipulatives to scientific evidence/data that was displayed in posters, images, and video clips. The participating scientists walked the ‚Äėaudience‚Äô through the hands-on manipulative, then discussed their evidence while provided the reasoning. Adjusting this linked manipulative/data approach to the community of teachers will provide a very tangible education outcome to this community from IPY. Our linked manipulative-data strategy ensures polar processes are demonstrated, measured then matched with IPY data sets so that when examined in a guided exploration will provide the student the tools to generate the reasoning. This linked strategy is a powerful way to engage students in Earth science, and provide them with an entry to the wealth of professionally collected data sets that are available from both IPY and the broader science community, all while aligning with National Science Standards. We will demonstrate this approach, and show how the linked manipulative-data approach can be effectively used in community and school events to reach a wider audience.

    Since 2007 I have been a Team Leader for the Tzec Maun Foundation, a non-profit foundation dedicated to providing free, research grade, Internet telescopes to students, teachers and researchers around the world. The name Tzec Maun (pronounced ‚ÄúTeh-Zeck-Moan‚ÄĚ) comes from Mayan culture. Tzec Maun was the jovial messenger, laughed at adversity. Based on the challenges students, researchers and professional astronomers face with finances, equipment, and telescope access, the jovial mascot seems to fit. Hundreds of hours performing astronomical outreach as a NASA/JPL Solar System Ambassador and Astronomical League Master of outreach taught me that the best way to inspirationally teach astronomy and space science (and most subjects) is actually being at the eyepiece. I‚Äôm NOT a fan of the traditional planetarium experience as a teaching tool because it inhibits inspiration and the learning experience to a 2-D mat on a faux horizon with artificial representations. Once, a student at my dark sky observatory excitedly commented that the night sky was like a 3-D planetarium. I have hosted several classes at my own personal dark sky observatory, but this resource is impractical for all but a few lucky students. Experience has taught me that the next best thing to being at the eyepiece is to control a remote telescope via the Internet. Tzec Maun‚Äôs arsenal of telescopes is all research capable, linked to the Internet and positioned for round-the-clock dark skies. The final conditions described above, mean that I can enter an 8:30am science class, log onto the Tzec Maun telescope Portal and turn over control of an Australian system (where it is night) to a student or teacher. Working as a group, the class can either begin their investigations. My Tzec Maun science team (TARP) is engaged in searching for potentially hazardous asteroids (PHAs). PHA work excites student and teacher alike. Teaching from telescopes can unleash powerful attention-getting tools that enable teachers to convey moderately complex computer science, optical, geographic, mathematical, informational and physical principles through hands-on telescope operations. In addition to the general studies aspects of classroom internet-based astronomy, Tzec Maun supports real science by enabling operators precisely point telescopes and acquire extremely faint, magnitude 19+ CCD images. Thanks to the creative Team of Photometrica (photometrica.org), my teams now have the ability to process and analyze images online and produce results in short order. Normally, astronomical data analysis packages cost greater than thousands of dollars for single license operations. Free to my team members, Photometrica allows students to upload their data to a cloud computing server and read precise photometric and/or astrometric results. I‚Äôm indebted to Michael and Geir for their support. The efficacy of student-based research is well documented. The Council on Undergraduate Research defines student research as, "an inquiry or investigation conducted by an undergraduate that makes an original intellectual or creative contribution to the discipline." (http://serc.carleton.edu/introgeo/studentresearch/What. Teaching from Tzec Maun in the classroom is the most original teaching research I can imagine. I very much look forward to presenting this program to the convened body.

    Over the past decade, Sandia National Laboratories has been involved in the development of receivers to transfer energy from the focus of a parabolic dish concentrator to the heater tubes of a Stirling engine. Through the isothermal evaporation and condensation of sodium. a heat-pipe receiver can efficiently transfer energy to an engine's working fluid and compensate for irregularities in the flux distribution that is delivered by the concentrator. The operation of the heat pipe is completely passive because the liquid sodium is distributed over the solar-heated surface by capillary pumping provided by a wick structure. Tests have shown that using a heat pipe can boost the system performance by twenty percent when compared to directly illuminating the engine heater tubes. Designing heat pipe solar receivers has presented several challenges. The relatively large area ({approximately}0.2 m{sup 2}) of the receiver surface makes it difficult to design a wick that can continuously provide liquid sodium to all regions of the heated surface. Selecting a wick structure with smaller pores will improve capillary pumping capabilities of the wick, but the small pores will restrict the flow of liquid and generate high pressure drops. Selecting a wick that is comprised of very tine filaments can increase the permeability of the wick and thereby reduce flow losses, however, the fine wick structure is more susceptible to corrosion and mechanical damage. This paper provides a comprehensive review of the issues encountered in the design of heat pipe solar receivers and solutions to problems that have arisen. Topics include: flow characterization in the receiver, the design of wick systems. the minimization of corrosion and dissolution of metals in sodium systems. and the prevention of mechanical failure in high porosity wick structures.

    While there has long been a general consensus among science researchers and educators that practical work is an essential component of teaching science, there is little agreement about the purposes of undergraduate laboratory courses. The aims of these courses are often manifold and confusingly combined. As part of the reform taking place in the undergraduate physics curriculum at Texas Tech University, we aim to develop laboratory activities which promote students' understanding of the nature of measurement and uncertainty, while providing opportunities for students to apply learned concepts to new situations through experiment and observation. Our goal is to construct a laboratory curriculum which reflects science practice, and highlights the nature of science and the process of scientific inquiry. The activities are based on the probabilistic approach to measurement, and a modelling framework for physics teaching and learning. The development of these activities will be discussed; and examples from an introductory calculus-based laboratory course will be presented.

    This exercise sets up a collaborative activity that challenges students to develop a chromatographic solvent with the appropriate polarity to separate leaf chlorophyll and anthocyanin pigments by TLC. The suggested activity has been tested with both high-school advanced-chemistry students and with undergraduate students in an introductory biochemistry class. It includes a demonstration introducing the basic principles of partitioning and differential distribution based on solubility. For the student activity, the materials to be used are leaves of the variegated Coleus plant, plastic-backed silica TLC plates, 2-propanol, acetone, and methanol. Students may work collaboratively within a set of boundary parameters to optimize the chromatographic solvent through a series of rapid iterations of chromatography. Students can also use these chromatography systems to carry out independent projects.

    Mice that ingested a suspension of guarana (Paullinia cupana, Sapindaceae) in a dose of 0.3 mg/ml showed a significant increase in physical capacity when subjected to a stressful situation such as forced swimming after 100 and 200 days of treatment. Such an effect, however, was not obtained with a concentration of 3.0 mg/ml, nor with the ingestion of a suspension of ginseng 5.0 mg/ml, nor of a solution of caffeine 0.1 mg/ml. Guarana, both after a single (3.0 and 30 mg/kg) or chronic administrations (0.3 mg/ml), was able to partially reverse the amnesic effect of scopolamine as measured through a passive avoidance test in mice and rats, indicating a positive effect on memory acquisition. However, no effect was observed when an active avoidance task was used in rats, even after 20 days of guarana administration. There was also a tendency of rats treated with 0.3 mg/ml of guarana to better maintain the memory of a Lashley III maze path. The animals had the same average lifespan, indicating a low toxicity of guarana, even after 23 months of treatment. PMID:9080343

    For SSRL operations, 1988 was a year of stark contrasts. The first extended PEP parasitic running since the construction of our two beam lines on that storage ring took place in November and December. Four experiments discussed below, were performed and detailed operational procedures which allowed synchrotron radiation an high energy users to coexist were established. SSRL anticipates that there will be significant amounts of beam time when PEP is run again for high energy physics. On the other hand, activity on SPEAR consisted of brief parasitic running on the VUV lines in December when the ring was operated at 1.85 GeV for colliding beam experiments. There was no dedicated SPEAR running throughout the entire calendar year. This is the first time since dedicated SPEAR operation was initiated in 1980 that there was no such running. The decision was motivated by both cost and performance factors, as discussed in Section 1 of this report. Fortunately, SLAC and SSRL have reached an agreement on SPEAR and PEP dedicated time charges which eliminates the cost volatility which was so important in the cancellation of the June-July dedicated SPEAR run. As discussed in Section 2, the 3 GeV SPEAR injector construction is proceeding on budget and on schedule. The injector will overcome the difficulties associated with the SLC-era constraint of only two injections per day. SSR and SLAC have also embarked on a program to upgrade SPEAR to achieve high reliability and performance. As a consequence, SSRL`s users may anticipate a highly effective SPEAR by 1991, at the latest. At that time, SPEAR is expected to be fully dedicated to synchrotron radiation research and operated by SSRL. Also contained in this report is a discussion of the improvements to SSRL`s experimental facilities and highlights of the experiments of the past year.

    Genomics and proteomics have emerged as key technologies in biomedical research, resulting in a surge of interest in training by investigators keen to incorporate these technologies into their research. At least two types of training can be envisioned in order to produce meaningful results, quality publications and successful grant applications: (1) immediate short-term training workshops and (2) long-term graduate education or visiting scientist programs. We aimed to fill the former need by providing a comprehensive hands-on training course in genomics, proteomics and informatics in a coherent, experimentally-based framework. This was accomplished through a National Heart, Lung, and Blood Institute (NHLBI)-sponsored 10-day Genomics and Proteomics Hands-on Workshop held at National Jewish Health (NJH) and the University of Colorado School of Medicine (UCD). The course content included comprehensive lectures and laboratories in mass spectrometry and genomics technologies, extensive hands-on experience with instrumentation and software, video demonstrations, optional workshops, online sessions, invited keynote speakers, and local and national guest faculty. Here we describe the detailed curriculum and present the results of short- and long-term evaluations from course attendees. Our educational program consistently received positive reviews from participants and had a substantial impact on grant writing and review, manuscript submissions and publications. PMID:24316330

    The critical need for enhancing influenza pandemic preparedness in many developing nations has led the World Health Organization (WHO) and the Biomedical Advanced Research and Development Authority (BARDA), part of the U.S. Department of Health and Human Services (HHS), to develop an international influenza vaccine capacity-building program. Among the critical limitations faced by many of these nations is lack of access to training programs for staff supporting operations within vaccine production facilities. With support from BARDA, the Biomanufacturing Training and Education Center (BTEC) at North Carolina State University has addressed this need for training by developing and delivering a comprehensive training program, consisting of three courses: Fundamentals of cGMP Influenza Vaccine Manufacturing, Advanced Upstream Processes for Influenza Vaccine Manufacturing, and Advanced Downstream Processes for Influenza Vaccine Manufacturing. The courses cover process design, transfer, and execution at manufacturing scale, quality systems, and regulations covering both manufacturing and approval of pandemic vaccines. The Fundamentals course focuses on the concepts, equipment, applicable regulations, and procedures commonly used to produce influenza vaccine. The two Advanced courses focus on process design, scale up, validation, and new technologies likely to improve efficiency of vaccine production. All three courses rely on a combination of classroom instruction and hands-on training in BTEC's various laboratories. Each course stands alone, and participants may take one or more of the three courses. Overall participant satisfaction with the courses has been high, and follow-up surveys show that participants actively transferred the knowledge they gained to the workplace. Future plans call for BTEC to continue offering the three courses and to create an online version of several modules of the Fundamentals course. PMID:25132407

    Created in 1994 in the wake of the closure of the Space Camp of Patrick Baudry in Cannes, Classes Azur Astro Espace (AAE) provide a world's unique combination of space and astronomy courses, as given by active and retired professionals of two of the best space and astronomical facilities extant: Alcatel Space in Cannes and Observatoire de la C√īte d'Azur (OCA) in Nice, Grasse and Caussols. Fifteen space modules, of 30 to 60 minutes each, have been established, giving simple and clear explanations on launchers, satellites, their applications, their development, together with an historical background. Basic experiments are included, such as an unique small catapult to explain gravity, or more classical water rockets. The basic AAE sojourn extends over 3 days: one day for space (including a visit of Alcatel Space, the biggest satellite manufacturer outside the US and Russia), one day for astronomy (including a visit of the biggest observatory in Europe) and one day √†-la-carte (C√īte d'Azur offers much, such as the Oceanographic Museum in Monaco). More and more groups are adding a fourth day, with a visit to the nice old village of Perinaldo in Italy, where famous astronomer Cassini was born. Lyc√©e de Cachan, near Paris, even takes 12-day sojourns every year. The public has been extremely wide, from age 5 to 70, from students to enthusiasts. Coming initially all over from France, participants now include since 2001 German and Italian pupils and teachers. In 2001 also, ESA came in the shape of a Space Camp. ISU's Master of Space Studies participates to a shortened version of AAE every even-year. Up to the end of 2001, 62 classes with 2,025 participants from 20 countries had thus come to enjoy space education on C√īte d'Azur. Such success is due in no small part to the very attractive price and flexibility of these activities, notably thanks to the support of ESA, CNES, Rectorat d'Acad√©mie de Nice, Conseil G√©n√©ral des Alpes-Maritimes, Ville de Cannes, AAAF, TDF, Alcatel Space and OCA.

    As announced in the paper presented in Toulouse, a trinational teacher training program addressing school teachers from France, Germany and Italy on teaching foreign languages together with science and history through Space related projects has been implemented and launched successfully. Supported by the French Ministry of Education (Académie de Nice), the bigovernmental French-German Youth Office (Office franco- allemand pour la Jeunesse) and the European Space Agency the first session was held in Cannes in October 2001 and brought together 36 language, science and history teachers, 12 from each country. Through different workshops, presentations and visits this five-day training encounter initiated the participants with Space activities and exploration as well as offering them back-up information on astronomy. It gave them furthermore the opportunity of improving their linguistic skills and of exchanging their teaching experience. The program was highly welcomed by all the participants who will meet this year in Germany for the second session devoted to establishing together bi- or trinational projects for future class encounters based on the same subjects. My paper will deal with the results of the program which have been beyond expectation and will encourage us to continue this pluridisciplinary approach of language &science teaching and extend it to other language combinations.

    Each country participating on the International Space Station (ISS) recognizes the importance of educating the coming generation about space and its opportunities. In 2001 the St. James School in downtown Houston, Texas was approached with a proposal to renovate an unused classroom and become involved with the "GLOBE" Program and other Internet based international learning resources. This inner-city school willingly agreed to the program based on "hands-on" learning. One month after room conversion and ten computer terminals donated by area businesses connectivity established to the internet the students immediately began using the "Global Learning and Observations to Benefit the Environment (GLOBE)" program and the International Space Station (ISS) Program educational resources. The "GLOBE" program involves numerous scientific and technical agencies studying the Earth, who make it their goal to provide educational resources to an international community of K-12 scientist. This project was conceived as a successor to the "Interactive Elementary Space Museum for the New Millennium" a space museum in a school corridor without the same type of budget. The laboratory is a collaboration, which involved area businesses, volunteers from the NASA/Johnson Space Center ISS Outreach Program, and students. This paper will outline planning and operation of the school science laboratory project from the point of view of the schools interest and involvement and assess its success to date. It will consider the lessons learned by the participating school administrations in the management of the process and discuss some of the issues that can both promote and discourage school participation in such projects.

    During the summer of 2011, the MńĀlama Ke Ahupua`a (to care of our watershed) GEARUP summer program provided 25 under-served and under-represented minority public high school students (Hawaiian, part-Hawaiian, Filipino, Pacific Islanders) from Farrington High School (Kalihi, Honolulu) with a hands-on place-based multidiscipline course located within Manoa Valley (Ahupua`a O Kona) with the objective of engaging participants in scientific environmental investigations while exploring Hawaii's linkages between traditional knowledge, culture and science. The 4-week field program enabled students to collect samples along the perennial Manoa Stream and conduct water quality assessments throughout the Manoa watershed. Students collected science quality data from eight different sampling stations by means of field- and laboratory-based quantitative water quality testing equipment and GPS/GIS technology. While earning Hawaii DOE academic credits, students were able to document changes along the stream as related to pollution and urbanization. While conducting the various scientific investigations, students also participated in cultural fieldtrips and activities that highlighted the linkages between historical sustainable watershed uses by native Hawaiian communities, and their connections with natural earth processes. Additionally, students also participated in environmental service-learning projects that highlight the Hawaiian values of laulima (teamwork), mńĀlama (to care for), and imi `ike (to seek knowledge). By contextualizing and merging hands-on place-based earth science inquiry with native Hawaiian traditional knowledge, students experienced the natural-cultural significance of their ahupua`a (watershed). This highlighted the advantages for promoting environmental literacy and geoscience education to under-served and under-represented minority populations in Hawaii from a rich native Hawaiian cultural framework.

    Older adults' preferences to remain independent in their own homes along with the high costs of nursing home care have motivated the development of Ambient Assisted Living (AAL) technologies which aim at improving the safety, health conditions and wellness of the elderly. This paper reports hands-on experiences in designing, implementing and operating UbiCare, an AAL based prototype system for elderly home care monitoring. The monitoring is based on the recording of environmental parameters like temperature and light intensity as well as micro-level incidents which allows one to infer daily activities like moving, sitting, sleeping, usage of electrical appliances and plumbing components. The prototype is built upon inexpensive, off-the-shelf hardware (e.g., various sensors, Arduino microcontrollers, ZigBee-compatible wireless communication modules) and license-free software, thereby ensuring low system deployment costs. The network comprises nodes placed in a house's main rooms or mounted on furniture, one wearable node, one actuator node and a centralized processing element (coordinator). Upon detecting significant deviations from the ordinary activity patterns of individuals and/or sudden falls, the system issues automated alarms which may be forwarded to authorized caregivers via a variety of communication channels. Furthermore, measured environmental parameters and activity incidents may be monitored through standard web interfaces. PMID:26094631

    In this work, various alternative teaching methods and activities for chemical education are developed, presented, and evaluated. In the first study, an original hands-on activity using LEGO¬ģ blocks to model ionic chemical formulas is presented together with quantitative and qualitative data regarding its educational effectiveness. Students explore cation to anion ratios using LEGO¬ģ blocks to represent trivalent, divalent and monovalent cations and anions. High school chemistry students who participated in the LEGO¬ģ lab showed significantly higher post-test scores than other students. The second study grows out of the creation of a computational lab module that is shown to significantly increase student learning in the subject of molecular orbital theory in first semester college General Chemistry. The third and final study presented is a course redesign project for college CHEM 1100, Preparation for General Chemistry. In this project the classroom is ‚Äúflipped‚ÄĚ. Students watch video lectures at home, and spend class time working with peers and the instructor on problem solving activities. The results presented here are one of the first quantitative studies showing the effectiveness of ‚Äúflipping the classroom‚ÄĚ. Students who were taught using the Reverse-Instruction (RI) method had significantly higher success in both the Preparation for General Chemistry course and traditionally taught General Chemistry I the following semester.

    Science and technology are widely recognized as major drivers of innovation and industry (e.g. Rising above the Gathering Storm, 2006). While the focus for education reform is on school improvement, there is considerable research that supports the role that out-of-school experiences can play in student achievement and public understanding of STEM disciplines. Libraries provide an untapped resource for engaging underserved youth and their families in fostering an appreciation and deeper understanding of science and technology topics. Designed spaces, like libraries, allow lifelong, life-wide, and life-deep learning to take place though the research basis for learning in libraries is not as developed as other informal settings like science centers. The Space Science Institute’s National Center for Interactive Learning (NCIL) in partnership with the American Library Association (ALA), the Lunar and Planetary Institute (LPI), and the National Girls Collaborative Project (NGCP) have received funding from NSF to develop a national education project called the STAR Library Education Network: a hands-on learning program for libraries and their communities (or STAR-Net for short). STAR stands for Science-Technology, Activities and Resources. The overarching goal of the project is to reach underserved youth and their families with informal STEM learning experiences. This project will deepen our knowledge of informal/lifelong learning that takes place in libraries and establish a learning model that can be compared to the more established free-choice learning model for science centers and museums. The project includes the development of two STEM hands-on exhibits on topics that are of interest to library staff and their patrons: Discover Earth and Discover Tech. In addition, the project will produce resources and inquiry-based activities that libraries can use to enrich the exhibit experience. Additional resources will be provided through partnerships with relevant professional science and technology organizations (e.g. American Geophysical Union; National Academy of Engineering) that will provide speakers for host library events and webinars. Online and in-person workshops will be conducted for library staff with a focus on increasing content knowledge and improving facilitation expertise. This presentation will report on strategic planning activities for STAR-Net, a Community of Practice model, and the evaluation/research components of this national education program.

    OBJECTIVE To determine whether there is a relationship in family medicine between higher overall job satisfaction and doing a wider range of procedures. DESIGN Secondary analysis of a population survey (mailed questionnaire) using multiple regression analysis. SETTING Canadian family practices. PARTICIPANTS Family physicians who responded to the 2001 National Family Physician Workforce Survey conducted by the College of Family Physicians of Canada and whose main practice settings were private offices or clinics, community clinics, community health centres, or academic family medicine teaching units. MAIN OUTCOME MEASURES Family physicians’ overall job satisfaction. The predictor variable was range of procedures performed, defined as the variety of procedures done by family physicians. Eight potential confounding variables were examined: age; sex; solo versus group practice; population served by practice (urban, semiurban, rural); number of medical services offered; teaching (yes, no); constraints to medical care services; and the balance of physicians’ personal and professional commitments. RESULTS Of 19 762 physicians who responded to the question on job satisfaction, 15.8% were dissatisfied, 54.3% were moderately satisfied, and 29.8% were very satisfied overall. In multiple regression analysis, when controlling for confounding variables, the range of procedures done by family physicians was significantly associated with overall job satisfaction (P = .0001). The larger the range of procedures, the more satisfied the physician. The percentage of those very satisfied ranged from 28.1% for family physicians who did only a few procedures (0 to 4) to 33.5% for those who did 10 or more procedures. Greater satisfaction was reported by very young and very old male physicians, those in solo practice, rural physicians, teachers, those who had fewer constraints to medical care services, and those who thought their balance of personal and professional commitments was about right. CONCLUSION Family physicians might improve their overall job satisfaction by increasing the range of procedures they do. This modest association has not been described previously. PMID:17872615

    Institutions of higher education, states, and local K-12 districts have been challenged to improve math and science education for our nation's students. In the past few years, there has been renewed interest in inquiry-based, activity-oriented instruction in science for students with disabilities. Yet, there still exists the need for further empirical evidence to support instructional improvements for students with more involved emotional and behavioral disabilities. This study describes a program in which 18 middle school students with serious emotional disturbances were instructed, over the course of 8 weeks, on Matter by two different instructional approaches. Students in one classroom received a traditional textbook approach to science content, whereas students in another classroom received science instruction by a hands-on, thematic approach. Over the course of instruction, data were collected regarding students' behavior and achievement. Results indicate that, overall, students in the hands-on instructional program performed significantly better than the students in the textbook program on two of three measures of science achievement, a hands-on assessment and a short-answer test. The students did not differ on a multiple-choice format test. With regard to behavior, there were no significant differences in behavioral problems found between the two groups of students over the course of the study. Findings are discussed in relation to instructional implications for students with disabilities in the science classroom.

    The Hands-On Optics project offers an example of a set of instructional modules that foster active prolonged engagement. Developed by SPIE, OSA, and NOAO through funding from the U.S. National Science Foundation, the modules were originally designed for afterschool settings and museums. However, because they were based on national standards in mathematics, science, and technology, they were easily adapted for use in classrooms. The philosophy and implementation strategies of the six modules will be described as well as lessons learned in training educators. The modules were implementing with the help of optics industry professionals who served as expert volunteers to assist educators. A key element of the modules was that they were developed around an understanding of optics misconceptions and used culminating activities in each module as a form of authentic assessment. Thus student achievement could be measured by evaluating the actual product created by each student in applying key concepts, tools, and applications together at the end of each module. The program used a progression of disciplinary core concepts to build an integrated sequence and crosscutting ideas and practices to infuse the principles of the modern electro-optical field into the modules. Whenever possible, students were encouraged to experiment and to create, and to pursue inquiry-based approaches. The result was a program that had high appeal to regular as well as gifted students.

    We developed a hands-on laboratory exercise for undergraduate students in which they can build and manipulate a neuron equivalent circuit. This exercise uses electrical circuit components that resemble neuron components and are easy to construct. We describe the methods for creating the equivalent circuit and how to observe different neuron properties through altering the structure of the equivalent circuit. We explain how this hands-on laboratory activity allows for the better understanding of this fundamental neuroscience concept. At the conclusion of this laboratory exercise, undergraduate students will be able to apply the principles of Ohm's law, cable theory with regards to neurons, and understand the functions of resistance and capacitance in a neuron.

    We present a simple laboratory activity for introductory-level physics students which involves rolling balls down pipes and analysing their subsequent flight trajectories. Using balls of equal size but different mass allows students to confront their misconceptions of a mass dependence of the exit speed of the balls from the pipes. The concepts of conservation of energy and projectile motion are also utilized as students analyse their data graphically. Adding in concepts of rotational motion improves the predictions. This is a safe and inexpensive laboratory exercise that allows students to clearly see the power of model predictions in understanding the behaviour of physical systems.

    We present a novel laboratory activity on RC circuits aimed at introductory physics students in life-science majors. The activity teaches principles of RC circuits by connecting ac-circuit concepts to bioelectrical impedance analysis (BIA) using a custom-designed educational BIA device. The activity shows how a BIA device works and how current, voltage, and impedance measurements relate to bioelectrical characteristics of the human body. From this, useful observations can be made including body water, fat-free mass, and body fat percentage. The laboratory is engaging to pre-health and life-science students, as well as engineering students who are given the opportunity to observe electrical components and construction of a commonly used biomedical device. Electrical concepts investigated include alternating current, electrical potential, resistance, capacitance, impedance, frequency, phase shift, device design, and the use of such topics in biomedical analysis.

    Since the appearance in 1986 of epidemic of bovine spongiform encephalopathy (BSE), a new form of neurological disease in cattle which also affected human beings, many diagnostic and research activities have been performed to develop detection and therapeutic tools. A lot of progress was made in better identifying, understanding and controlling the spread of the disease by appropriate monitoring and control programs in European countries. This paper reviews the recent knowledge on pathogenesis, transmission and persistence outside the host of prion, the causative agent of transmissible spongiform encephalopathies (TSE) in mammals with a particular focus on risk (re)assessment and management of biosafety measures to be implemented in diagnostic and research laboratories in Belgium. Also, in response to the need of an increasing number of European diagnostic laboratories stopping TSE diagnosis due to a decreasing number of TSE cases reported in the last years, decontamination procedures and a protocol for decommissioning TSE diagnostic laboratories is proposed.

    We compared learning cycle and expository formats for teaching about plant biodiversity in an inquiry-oriented university biology lab class (n = 465). Both formats had preparatory lab activities, a hands-on lab, and a postlab with reflection and argumentation. Learning was assessed with a lab report, a practical quiz in lab, and a multiple-choice exam in the concurrent lecture. Attitudes toward biology and treatments were also assessed. We used linear mixed-effect models to determine impacts of lab style on lower-order cognition (LO) and higher-order cognition (HO) based on Bloom's taxonomy. Relative to the expository treatment, the learning cycle treatment had a positive effect on HO and a negative effect on LO included in lab reports; a positive effect on transfer of LO from the lab report to the quiz; negative impacts on LO quiz performance and on attitudes toward the lab; and a higher degree of perceived difficulty. The learning cycle treatment had no influence on transfer of HO from lab report to quiz or exam; quiz performance on HO questions; exam performance on LO and HO questions; and attitudes toward biology as a science. The importance of LO as a foundation for HO relative to these lab styles is addressed. PMID:25185232

    It often takes one single event to interest teenagers in a topic that will become a passion or a career. It is in this spirit that the SPIE and OSA Student Chapters at Université Laval created the Photonic Games three years ago, to kindle an interest in teenagers towards studies and careers in optics. The activity, offered each year to more than a hundred grade 11 students, is divided in two parts. First, we offer a hands-on workshop in their classrooms about reflection, refraction, dispersion, birefringence and polarization. A few days later, all the students come to the Centre d'optique, photonique et laser (COPL) at Université Laval for a day of competition where a volunteer physics student accompanies each team of four students. Challenges are various to promote the qualities that make great scientists: creativity, teamwork, knowledge, inquisitiveness, self-confidence and perseverance. The first two editions of the Photonic Games have proven to be beneficial for the students, teachers and volunteers, and we endeavor to improve it as we construct on our experience with the past editions to fine-tune and improve the Photonic Games concept.

    2010-09-11

    Dose rates from accelerator components activated by 1 W/m beam losses are obtained semiempirically for a 1 GeV proton beam and by use of Monte Carlo transport codes for the proton beam and for 777 MeV/u 3He, 500 MeV/u 48Ca, 86Kr, 136Xe, and 400 MeV/u 238U ions. The dose rate obtained by the semi-empirical method, 0.99 mSv/h (99 mrem/h) at 30 cm, 4 h after 100 d irradiation by a 1-GeV proton beam, is consistent with studies at several accelerator facilities and with adopted hands-on maintenance dose rate limits. Monte Carlo simulations verify this result for protons and extend studies to heavy ion beam losses in drift-tube linac and superconducting linac accelerating structures. The studies indicate that the 1 W/m limit imposed on uncontrolled beam losses for high-energy proton beams might be relaxed for heavy ion beams. These studies further suggest that using the ratio of neutrons produced by a heavy ion beam to neutrons produced by a proton beam along with the dose rate from the proton beam (for thin-target scenarios) should allow an estimate of the dose rates expected from heavy ion beam losses.

    Active learning is one of the most efficient mechanisms for learning, according to the psychology of learning. When students act as teachers for other students, the communication is more fluent and knowledge is transferred easier than in a traditional classroom. This teaching method is referred to in the literature as reciprocal peer teaching. In this study, the method is applied to laboratory sessions of a higher education institution course, and the students who act as teachers are referred to as "laboratory monitors." A particular way to select the monitors and its impact in the final marks is proposed. A total of 181 students participated in the experiment, experiences with laboratory monitors are discussed, and methods for motivating and training laboratory monitors and regular students are proposed. The types of laboratory sessions that can be led by classmates are discussed. This work is related to the changes in teaching methods in the Spanish higher education system, prompted by the Bologna Process for the construction of the European Higher Education Area

    Edoxaban, an oral direct inhibitor of factor Xa, was recently approved in the United States and Japan for prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation and for treatment of venous thromboembolism (VTE). It is also licensed in Japan for prevention of VTE after major orthopedic surgery. Although routine laboratory monitoring of edoxaban is not required, laboratory measurement may be desirable in special circumstances. Our objective was to provide a systematic review of current evidence on laboratory measurement of the anticoagulant activity of edoxaban. PubMed and the Cochrane Library were searched for studies that reported a relationship between coagulation tests and plasma edoxaban levels. Study quality was assessed using Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2). We identified 9 eligible studies. Anti-Xa activity is linear across a broad range of drug levels (R (2) > 0.95) and may be used for edoxaban quantification. The assay shows greater variability at above on-therapy drug concentrations. The PT is less sensitive to edoxaban. A normal prothrombin time may not exclude clinically relevant on-therapy drug levels. The activated partial thromboplastin time has insufficient sensitivity to edoxaban for measurement of its anticoagulant activity. Edoxaban exhibits variable effects on coagulation assays. Understanding these effects facilitates interpretation of test results in edoxaban-treated patients. More data on the relationship between drug levels, coagulation test results, and clinical outcomes in patients are needed. PMID:25669624

    The Systems Analysis Programs for Hands-on Integrated Reliability Evaluations (SAPHIRE) is a software application developed for performing a complete probabilistic risk assessment (PRA) using a personal computer. SAPHIRE is funded by the U.S. Nuclear Regulatory Commission (NRC) and developed by the Idaho National Laboratory (INL). The INL's primary role in this project is that of software developer. However, the INL also plays an important role in technology transfer by interfacing and supporting SAPHIRE users comprised of a wide range of PRA practitioners from the NRC, national laboratories, the private sector, and foreign countries. SAPHIRE can be used to model a complex system’s response to initiating events, quantify associated damage outcome frequencies, and identify important contributors to this damage (Level 1 PRA) and to analyze containment performance during a severe accident and quantify radioactive releases (Level 2 PRA). It can be used for a PRA evaluating a variety of operating conditions, for example, for a nuclear reactor at full power, low power, or at shutdown conditions. Furthermore, SAPHIRE can be used to analyze both internal and external initiating events and has special features for ansforming models built for internal event analysis to models for external event analysis. It can also be used in a limited manner to quantify risk in terms of release consequences to both the public and the environment (Level 3 PRA). SAPHIRE includes a separate module called the Graphical Evaluation Module (GEM). GEM provides a highly specialized user interface with SAPHIRE that automates SAPHIRE process steps for evaluating operational events at commercial nuclear power plants. Using GEM, an analyst can estimate the risk associated with operational events in a very efficient and expeditious manner. This reference guide will introduce the SAPHIRE Version 7.0 software. A brief discussion of the purpose and history of the software is included along with general information such as installation instructions, starting and stopping the program, and some pointers on how to get around inside the program. Next, database concepts and structure are discussed. Following that discussion are nine sections, one for each of the menu options on the SAPHIRE main menu, wherein the purpose and general capabilities for each option are furnished. Next, the capabilities and limitations of the software are provided.

  4. The Lanzarote Geodynamic Laboratory: new capabilities for monitoring of volcanic activity at Canary Islands

    The volcanic island of Lanzarote is located at the northeastern end of the Canary Islands. Together with Fuerteventura Island, Lanzarote constitutes the emergent part of the East Canary Ridge, which presents a NNE-SSW volcanic alignment. Last eruptive events took place in 1824 and during the period 1730-1736, which is the largest to occur in the archipelago and throw out about 1.3 km3 of volcanic materials. The Lanzarote Geodynamic Laboratory (LGL) was created in 1986 with the idea of making Lanzarote as a natural laboratory to carry out studies in order to acquire more knowledge about its origin, present status and evolution (Vieira et al., 1991; 2006). The LGL has a multidisciplinary scientific purpose and, among others, various objectives are devoted to investigate mass distribution in the Earth system and surface displacements associated to volcanic and/or seismic activity in the island. The influence of LGL is extended throughout the whole geographical area of Lanzarote, including small islands located at the north. The laboratory has 3 observing modules distributed along the island according to its infrastructure and scientific objectives, where more than 70 sensors are recording continuously gravity variations, ground deformations, sea level, seismic activity, meteorological parameters, etc. All these observations are supplemented by periodic measurement of geodetic and geophysical networks that allow us to make studies at local, insular and regional scales. The application of geodetic and geophysical techniques to identify geodynamic signals related to volcanic processes is then a permanent research activity of the laboratory. Nowadays, this fact becomes more interesting due to the ongoing volcanic eruption that is taking place in other island of the Canary Archipelago, El Hierro, since past July 2011. That is, the multidisciplinary research carry on up to now at the LGL allow us to apply multiparameter observations of different kinds of volcanic manifestations at the surface level, and to compare geodynamic processes associated with an active area of the Earth's crust. In turn, the results obtained can provide new inputs for studying precursor of volcanic activity and also contribute to volcanic hazard mitigation. The LGL aims to be a permanent status of renewal, using new technologies for data recording and real time transmission, as well as for testing new sensors, scientific equipment and observational techniques related to monitoring and observation of volcanic activity. All these capabilities are necessary when high-resolution ground based observations must provide us the basis for studying the sources of volcanic deformation. The laboratory is thus open to support and to enhance the collaboration among scientists, as well as national and international institutions involved in research at active volcanic areas.

    The specialised fauna of freshwater springs is affected by contamination of the water with xenobiotics from human activities in the surrounding landscape. We assessed the effects of exposure to toxins in laboratory and field experiments by using copper sulphate as a model substance and Gammarus fossarum Koch, 1836, as the model organism. This amphipod is a common representative of the European spring fauna and copper is a widespread contaminant, mainly from agricultural practice. The experiments were conducted in test chambers placed in flow channels and directly in a spring. The gammarids were fed with conditioned beech leaf discs, which had been exposed to a 0.8 mg Cu/L solution for 96 h. The feeding activity of the amphipods was quantified on the level of the organism; and the respiratory electron transport system (ETS) assay was conducted in order to determine changes on the cellular level in the test organisms. The results show that the feeding activity, when the leaf discs were contaminated with copper, was not significantly different from the control. The ETS activity of the gammarids, which had been feeding on the copper contaminated leaf discs was however significantly reduced. The results followed the same pattern for gammarids from both the laboratory and the spring. By conducting the experiments not only in a laboratory but also directly in a spring in the field, we took a crucial step towards a more realistic approach when examining environmental pollutants on an organism. Our findings demonstrate the importance of conducting experiments out in the field, in natural conditions, as well as in the laboratory. PMID:25704832

  13. Teaching reactions and stoichiometry: A comparison of guided inquiry and traditional laboratory activities

    Meister Thomas, Lynn

    There is a major movement in science education towards the inclusion of science inquiry and process. Guided-inquiry instruction is expected to have a positive impact on students' concrete and conceptual knowledge along with their ability to engage in the practices of science. This study examined the impact of inquiry-based teaching on student achievement. The topics of reactions and stoichiometry were taught in two different periods of first-year secondary honors chemistry. Both classes received the same lectures and assignments for this curriculum and both classes performed the same laboratory activities. However, one class received traditional, step-by-step (often called "cookbook") laboratory instructions while the other class developed their own procedures and made decisions about data to complete the laboratory activities. Pre- and post-tests were given to each class, followed by a test of retention after ten weeks. The results of this study indicate that inquiry-based instruction has a positive impact on student achievement. A significant increase between pre- and post- test scores for the experimental group as opposed to the scores for the control group suggests that achievement was correlated with guided inquiry instruction methods. Additionally, a notable trend suggested that guided inquiry instruction has a positive effect on learning retention.

The uses include as a portable passive neutron counter for field measurements searching for evidence of {sup 252}Cf deposits and storage; as a portable active neutron counter using an external activation source for field measurements searching for trace {sup 235}U deposits and holdup; for verification measurements of U-Al reactor fuel elements; for verification measurements of uranium metal; and for verification measurements of process waste of impure uranium in a challenging cement matrix. The wide variety of uses described demonstrate utility of the technique for neutron coincidence verification measurements over the dynamic ranges of 100 g-5000 g for U metal, 200 g-1300 g for U-Al, and 8 g-35 g for process waste. In addition to demonstrating use of the instrument in both the passive and active modes, we also demonstrate its use in both the fast and thermal neutron modes.

    STEM education at New Jersey City University increasingly focuses on experiential, student-centered learning. The Department of Geoscience/Geography plays a significant role in developing and implementing a new Urban Environmental Science Program. The program aims at graduating highly skilled, demographically diverse students (14 % African-American and 18% Hispanic) to be employed in high-growth Earth and Environmental Science career paths, both at a technical (e.g. B.S.) as well as an educational (K-12 grade) (e.g. B.A) level. The core program, including the Earth and Environmental Science curricula is guided by partners (e.g. USDA-NRCS). The program is highly interdisciplinary and 'hands-on', focusing upon the high-tech practical skills and knowledge demanded of science professionals in the 21st century. The focus of the curriculum is on improving environmental quality in northern NJ, centering upon our urban community in Jersey City and Hudson County. Our Department is moving towards a more earth system science approach to learning. Most of our courses (e.g., Earth Surface Processes, Sedimentology/Stratigraphy, Earth Materials, Essential Methods, Historical Geology) have hands-on laboratory and/or field components. Although some of our other courses do not have formal laboratory components, research modules of many such courses (Geochemistry, Urban Environmental Issues and Policy and Environmental Geology) involve strong field or laboratory studies. The department has a wide range of analytical and laboratory capacities including a portable XRF, bench-top XRD and ICP-MS. In spring 2013, Dr. Duzgoren-Aydin was awarded $277K in Higher Education Equipment Leasing Fund monies from the University in order to establish an Environmental Teaching and Research Laboratory. The addition of these funds will make it possible for the department to increase its instrumentation capacity by adding a mercury analyzer, Ion Chromatography and C-N-S analyzer, as well as updating several laboratory facilities. Furthermore, authors have applied to the NSF-TUES grant program to purchase a particle size analyzer. Currently, the grant is pending. We have defined 4 curricular goals to enhance student learning by providing hands-on, inquiry-based learning and research experiences. 1- Develop technical/analytical knowledge and skills by using advanced analytical instrumentation; 2- Improve quantitative reasoning skills to assess the quality of data; 3- Have comprehensive educational training to improve problem solving skills; and 4- use their quantitative reasoning (Goal # 2) and problem solving skills (Goal #3) to evaluate real-world geological and environmental problems. We also give special emphasis to expected measurable outcomes for individual courses. An external evaluator will assess the effectiveness of integrating advance instrumentation into the Earth and Environmental Science curricula. We will work closely with the evaluator to ensure successful implementation of the learning objectives. Examples from the impacted courses will be presented.

    We designed a three-week laboratory experience that can complement any microbiology teaching laboratory to expand students' knowledge of the ecology of human enteric pathogens outside of their animal hosts. Through their participation in this laboratory activity, students learned that vegetative and reproductive plant parts could be a natural habitat for enteric bacteria such as non-typhoidal strains of Salmonella enterica. This field was recently brought to the forefront of the scientific community and public interest by outbreaks of human illness linked to the consumption of fresh fruits and vegetables. Students were encouraged to develop their own testable hypotheses to compare proliferation of Salmonella enterica sv Typhimurium LT2 in different vegetables: cherry and regular-size tomatoes, onions, lettuce, and yellow and red bell peppers (Escherichia coli can be substituted for BSL1 laboratories). Upon completion of the laboratory experience, students were able to: 1) Develop testable hypotheses addressing the ability of a human pathogen, Salmonella enterica, to colonize and proliferate in vegetables; 2) Determine that different vegetables support the growth of Salmonella to different extents; 3) Conduct statistical analysis and identify any significant differences. The teaching-learning process was assessed with a pre-/posttest, with an average increase in content understanding from ~15% to 85%. We also measured students' proficiency while conducting specific technical tasks, revealing no major difficulties while conducting the experiments. Students indicated satisfaction with the organization and content of the practices. All of the students (100%) agreed that the exercises improved their knowledge of this subject. PMID:26753031

    The growing need in Algeria to develop ergonomics knowledge and practice in industry was behind the initiative to develop a training and research project within the ergonomics laboratory at Oran University. Since 2005 the laboratory team is running an academic option master in work design and ergonomics. The evaluation of the academic master in 2010 revealed the acute need of the local industry for professional competences in ergonomic and work psychology. A professional training master program in "ergonomics & work psychology" was then developed in partnership with local industry, five European Universities and six Universities from three Maghreb countries. Research projects were initiated around the two training programs, in conjunction with a number of ergonomics dissemination and promotion activities. Preliminary results of the project are presented and discussed in relation to the local context, and in the light of similar cases in Industrially Developing Countries. PMID:22316785

    The Idaho National Engineering Laboratory (INEL), in southeastern Idaho, is a principal center for nuclear energy development for the Department of Energy (DOE) and the U.S. Nuclear Navy. Fifty-two reactors have been built at the INEL, with 15 still operable. Extensive environmental surveillance is conducted at the INEL by DOE's Radiological Environmental Sciences Laboratory (RESL), and the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), EG&G Idaho, Inc., and Westinghouse Idaho Nuclear Company (WINCO). Surveillance of waste management facilities radiation is integrated with the overall INEL Site surveillance program. Air, warer, soil, biota, and environmental radiation are monitored or sampled routinely at INEL. Results to date indicate very small or no impacts from INEL on the surrounding environment. Environmental surveillance activities are currently underway to address key environmental issues at the INEL.

    For the past 7 years, high school students participating in the Astro-Science Workshop at the Adler Planetarium have been able to access the extreme environment of near space (approximately 30 km altitude) using high altitude balloons. Taking a hands-on approach the program has allowed students to design, build, and launch their own experiments with programming based at the Adler Planetarium. During flight, payloads are subjected to temperatures of around -65¬į C, atmospheric pressure of only 1% that at sea level, and cosmic radiation levels more than 60 times the surface background. In some ways, conditions at these altitudes are much like those at the surface of Mars, providing students with the opportunity to build and operate real-world analogs of interplanetary probes. We have found that this hands-on, student-driven research-based program is enhanced by implementing classroom and lab activities as well as by incorporating instruction and collaboration with research professionals currently active in the field of astronomy. We present the steps taken to implement the 2013 Astro-Science Workshop at the Adler Planetarium with a focus on daily instruction and operations planning and launch preparation.

    The Mars Science Laboratory (MSL) rover, Curiosity, which was launched on November 26, 2011, incorporates a novel active thermal control system to keep the sensitive electronics and science instruments at safe operating and survival temperatures. While the diurnal temperature variations on the Mars surface range from -120 C to +30 C, the sensitive equipment are kept within -40 C to +50 C. The active thermal control system is based on a single-phase mechanically pumped fluid loop (MPFL) system which removes or recovers excess waste heat and manages it to maintain the sensitive equipment inside the rover at safe temperatures. This paper will describe the entire process of developing this active thermal control system for the MSL rover from concept to flight implementation. The development of the rover thermal control system during its architecture, design, fabrication, integration, testing, and launch is described.

    Background: The present study aimed to investigate the Nailfold Capillaroscopy (NC) features of the patients with dermatomyositis (DM) and its correlation with their disease activity indices, physical findings, and laboratory results. Methods: The present cross-sectional study was conducted on 27 DM patients above 16 years old who had referred to an(there are 3 clinics not one) outpatient rheumatology clinics from 2012 to 2013. Nailfold capillaroscopy and calculation of disease activity indices were performed separately for all the patients by two rheumatologists who were blinded to each other's results. Statistical analyses were performed using chi-square and Mann-Whitney U tests. Results: The mean age of the patients was 39.2¬Ī14.1 years with the mean disease duration of 13.1¬Ī15.2 months (range: 1-72 months). Myopathic electromyography (EMG) findings showed a strong association with scleroderma pattern (p=0.015). However, disease activity in each organ system and global disease activity showed no significant association between scleroderma pattern and other NC findings. (Disease activity in each organ system and also global disease activity were both assessed to see if they are associated with scleroderma pattern and other NC findings so if we use between it means we are looking for an association between scleroderma pattern and other NC findings and this is not what we have done and is wrong.) Conclusion: This study revealed no significant relationship between disease activity indices and NC features. Thus, it may be more precise to interpret the results of NC in conjunction with other physical and laboratory findings. PMID:26793626

    The University of Texas Institute for Geophysics (UTIG), part of the Jackson School of Geosciences, annually offers a unique and intensive three-week marine geology and geophysics field course during the spring/summer semester intersession. Now entering its seventh year, the course transitions students from a classroom environment through real-world, hands-on field acquisition, on to team-oriented data interpretation, culminating in a professional presentation before academic and industry employer representatives. The course is available to graduate students and select upper-division undergraduates, preparing them for direct entry into the geoscience workforce or for further academic study. Geophysical techniques used include high-resolution multichannel seismic reflection, CHIRP sub-bottom profiling, multibeam bathymetry, sidescan sonar, sediment coring, grab sampling, data processing, and laboratory analysis of sediments. Industry-standard equipment, methods, software packages, and visualization techniques are used throughout the course, putting students ahead of many of their peers in this respect. The course begins with a 3-day classroom introduction to the field area geology, geophysical methods, and computing resources used. The class then travels to the Gulf Coast for a week of hands-on field and lab work aboard two research vessels: UTIG's 22-foot, aluminum hulled Lake Itasca; and NOAA's 82-foot high-speed catamaran R/V Manta. The smaller vessel handles primarily shallow, inshore targets using multibeam bathymetry, sidescan sonar, and grab sampling. The larger vessel is used both inshore and offshore for multichannel seismic, CHIRP profiling, multibeam bathymetry, gravity coring, and vibracoring. Field areas to date have included Galveston and Port Aransas, Texas, and Grand Isle, Louisiana, with further work in Grand Isle scheduled for 2014. In the field, students work in teams of three, participating in survey design, instrument set-up, field deployment, data acquisition optimization, quality control, data archival, log-keeping, real-time data processing, laboratory sediment analysis, and even boat-handling. Teams are rotated through the two vessels and the onshore field laboratory to ensure that each student has hands-on experience with each aspect of the process. Although all students work on all data areas in the field, after returning from the field each team is assigned a particular region or geologic problem to interpret. Each team prepares and presents a formal presentation to UTIG researchers and industry representatives, explaining and defending their interpretations. This unique approach to hands-on field training, real-world science, and project-based teamwork helps prepare students for direct entry into the workforce, giving them a leg up on competitors for positions. This course has an impressive success ratio to show, with many students receiving job offers directly as a result of their participation in the course.

    The technique which utilizes exposure to a plasma to remove contaminants from a surface was incorporated into a laboratory model which demonstrates active cleaning by both plasma cleaning and ion sputtering modes of operation. The development phase is reported and includes discussion of the plasma tube configuration, device design, and performance tests. A general description of the active cleaning device is provided which includes information on the main power/plasma discharge sensors, and the power, gas supply, and ion accelerator systems. Development of the active cleaning species at high vacuum conditions is described and results indicate that plasma cleaning occurs in the region of a visible plume which extends from the end of the plasma tube. Recommendations are made for research to determine the plasma cleaning mechanism and the plasma species responsible for the cleaning, as well limitations on the type of contaminants that can be removed.

    Cathodic protection (CP) is one practical and economical corrosion control option used to protect steel structures. The common sacrificial anodes used for CP system are aluminum (AL), and zinc (Zn) and their alloys. These three metals and their alloys can provide the starting basis for steel protection in sea water environment. actually many sacrificial anodes (SA) activation processes are widely used to improve the performance protection of steel . Based on the finding and the analysis of the results the aluminum and its alloys should be activated by the activation element rather than by cold working. However, activating the zinc and its alloys provides some improvement in the anode performance and could be considered as a reliable activation mechanism similar to the activation by alloying addition to zinc of similar purity. Finally, this paper discusses the use of cold working as a new activation mechanism, by using extensive laboratory investigation under simulated environmental conditions, and anode current capacity, polarization corrosion rates and protection ability were determined and discussed for this study.
