    Full Text Available This paper explores student initiative or student engagement in activities in school environment, as an aspect of students’ functioning that is assumed to be a prerequisite for their contribution to the quality of instruction and better use of possibilities for education and development in school environment. We approach this topic from teachers’ perspective since it is our aim to observe how teachers assess the initiative of their students (how important it is, how it is manifested, how present it is in different segments of school activities. In the first part of the paper we analyze the construct “student initiative” and a similar construct “student engagement”. In the second part of the paper we present the results of a research in which primary school teachers (N=182 from the territory of Serbia expressed their views on student initiative. Teachers’ answers to open- and close-ended questions from the questionnaire (19 items in total were processed by quantitative and qualitative methodology. Research results indicate that the majority of teachers believed that student initiative was a very important general feature of behavior in school environment, independent of age, which was most present in the domain of peer socializing and relationship with teachers, and least present in the very domains of student functioning that teachers deemed the most desirable (mastering the curriculum, regulation of disciplinary issues.

    Students in online courses continue to lag their peers in comparable face-to-face (F2F) courses (Ury 2004, Slater & Jones 2004). A meta-study of web-based vs. classroom instruction by Sitzmann et al (2006) discovered that the degree of learner control positively influences the effectiveness of instruction: students do better when they are in control of their own learning. In particular, web-based courses are more effective when they incorporate a larger variety of instructional methods. To address this need, we developed a series of online videos to demonstrate various astronomical concepts and provided them to students enrolled in an online introductory astronomy course at Penn State University. We found that the online students performed worse than the F2F students on questions unrelated to the videos (t = -2.84), but that the online students who watched the videos performed better than the F2F students on related examination questions (t = 2.11). We also found that the online students who watched the videos performed significantly better than those who did not (t = 3.43). While the videos in general proved helpful, some videos were more helpful than others. We will discuss our thoughts on why this might be, and future plans to improve upon this study. These videos are freely available on iTunesU, YouTube, and Google Video.

    Are pre-medical students different than the other students in a General physics class? They often appear to be different, based on how often they seek help from the instructor or how nervous they are about 2 points on a lab report. But are these students different in a measurable characteristic? The purpose of this study is to better understand the characteristics of the students in the introductory physics classes. This is the first step toward improving the instruction. By better understanding the students the classroom, the organization and pedagogy can be adjusted to optimize student learning. The characteristics to be investigated during this study are: · student epistemological structure, · student attitudes, · science course preparation prior to this course, · study techniques used, · physics concepts gained during the class · performance in the class. The data will be analyzed to investigate differences between groups. The groups investigated will be major, gender, and traditional/nontraditional students.

  7. Mentoring medical students in your general practice.

    Mentoring medical students in general practices is becoming more common in Australia due to formalised scholarship programs and informal approaches by students. This paper defines mentoring in Australian general practice. Practical suggestions are made on how to structure a mentorship program in your practice. Mentoring differs from leadership and teaching. It is a long-term relationship between a student and an experienced general practitioner. Avoiding summative assessment in mentorship is important to its success. Mentoring is about forming a safe place to confidentially discuss personal and professional issues between a mentor and student. This is based on defining roles and mutual trust. At the same time, students crave formative feedback. Unfortunately, present feedback models are based on teaching principles that can blur the differences between assessor, teacher and mentor. Mentorship can provide students with orientation and learning experiences so that they are prepared for practice as an intern.

    2014-05-01

    The school where I work is part of the "Step by step towards the sustainable development school" project. Project activities are partly directed towards the popularization of science. As a physics teacher, I have had the opportunity to engage in designing interactive workshops, aiming to introduce younger students to simple experiments which illustrate different natural phenomena, and also in organization, preparation and implementation of school and city science festival (in 2012 and 2013). Numerous displays, workshops and experiments served to introduce a large number of visitors to different topics in the area of science and technology. One of the subjects of forthcoming science festival, planned for May of 2014, is the climate change. To that effect, eight grade students will hold a demonstration and explanation of the greenhouse effect. Although the terms greenhouse effect and global warming are widely used in media, most of the elementary school students in Serbia have poor understanding of the underlying scientific concepts. The experiment with analysis and discussion will first be implemented in one eight-grade class (14 years of age). After that, a group of students from this class will present their newly-acquired knowledge to their peers and younger students at the science fair. Activity objectives: • Explain how atmosphere affects the surface temperature of Earth • Conduct an experiment to demonstrate the greenhouse effect • Analyze the consequences of climate changes Experiment description: Take two empty, transparent containers and add a layer of garden soil. Use cardboard or similar material to make housings for the thermometers. Hang them in the containers, so that they don't touch the soil. Cover one container with a glass panel, and leave the other one open. Place identical incandescent light bulbs at the same distance above each container. Turn the light bulbs on. The students should mark the thermometer readings every 2 minutes, for 20

    Surgical education is evolving under the dual pressures of an enlarging body of knowledge required during residency and mounting work-hour restrictions. Changes in surgical residency training need to be based on available educational models and research to ensure successful training of surgeons. Experiential learning theory, developed by David Kolb, demonstrates the importance of individual learning styles in improving learning. This study helps elucidate the way in which medical students, surgical residents, and surgical faculty learn. The Kolb Learning Style Inventory, which divides individual learning styles into Accommodating, Diverging, Converging, and Assimilating categories, was administered to the second year undergraduate medical students, general surgery resident body, and general surgery faculty at the University of Alberta. A total of 241 faculty, residents, and students were surveyed with an overall response rate of 73%. The predominant learning style of the medical students was assimilating and this was statistically significant (p learning style found in the residents and faculty. The predominant learning styles of the residents and faculty were convergent and accommodative, with no statistically significant differences between the residents and the faculty. We conclude that medical students have a significantly different learning style from general surgical trainees and general surgeons. This has important implications in the education of general surgery residents.

    This study used role-play demonstrations to train medical students to communicate drug therapy and evaluated the perceptions on this instructional approach. The second-year medical students who attended a prescription writing session (n = 133), participated in this study. Prescription communication was introduced by using role-play demonstrations. Participant's perceptions were explored by a self-administered questionnaire and focus group discussion. The academic achievement of attendees and nonattendees was compared with an objective structured performance evaluation (OSPE) station that tested students' competence in this skill. Most attendees responded to the questionnaire (81.2%). Almost all respondents expressed their desire to have similar demonstrations in other units. A large proportion of participants reported that role-play demonstrations helped them develop their communication skills, in general, confidence to communicate drug-related information in a prescription, and the ability to explain the aim of drug therapy to patients. Most trainees thought also that they developed skills to communicate instructions on drug use including drug dose, frequency of administration, duration of therapy, adverse drug reactions, and warnings. During the focus group interviews, students thought that role-play was useful but would be more beneficial if conducted frequently in small group as part of the curriculum implementation. The majority of students also reported improved competence in writing a complete prescription. Analysis of attendees and nonattendees grades in the OSPE showed that the former scored higher than the latter group (P = 0.016). Role-play demonstrations were well accepted by medical students and led to the development of their competence in communicating drug therapy to patients.

    The main objective of the study was to see whether medical students use more desirable approaches to studying than general education students. Survey method was used to collect data from both the medical students and the general education students. The survey of the medical students was carried out between January and March, 2012. The survey was administered to all the medical students present in lecture halls on day of data collection, while general education students were randomly selected from four subject areas at two universities. In total, 976 medical students and 912 general students participated in the study. Of the general students, 494(54%) were boys and 418(46%)were girls with an overall mean age of 20.53±1.77 years (range: 17-27 years). The medical students' perceptions of their learning environment and their learning preferences were broadly similar to that of general education students with the exception of workload. The medical students perceived the workload to be less appropriate (Mean = 2.06±0.72) than the students in general education (Mean = 2.84±0.90). The medical students were more likely to use the deep approach to studying (Mean = 3.66±0.59) than the students in general education (Mean = 3.16±0.91). The students in general education were slightly more likely to use the organized studying (Mean = 3.44±0.90) than the medical students (Mean =3.23±0.90). Both medical students and the students in general education tended to use the surface approaches along with other approaches to studying. There was not a great difference between the medical students and the students pursuing general education with regard to perceptions of the learning environment and approaches to learning.

    Analysis of self-reflections of undergraduate education students in a project involving web-supported counterintuitive science demonstrations is reported in this paper. Participating students (N = 19) taught science with counterintuitive demonstrations in local elementary school classrooms and used web-based resources accessed via wireless USB adapters. Student reflections to seven questions were analyzed qualitatively using four components of reflection (meeting objectives/perception of learning, dynamics of pedagogy, special needs accommodations, improving teaching) deriving 27 initial data categories and 12 emergent themes. Overall the undergraduates reported meeting objectives, engaging students in pedagogically relevant learning tasks including, providing accommodations to students with special needs, and gaining practice and insight to improve their own teaching. Additional research is needed to arrive at generalizable findings concerning teaching with web-supported counterintuitive science demonstrations in elementary classrooms.

    A 60/40 ratio has been estimated as a country's ideal proportion between general practitioners and specialists. In Chile this proportion was 36/ 64 in 2004, exactly the opposite of the ideal. Trends towards specialization or general practice among medical students have not been thoughtfully studied. To assess trends among medical students towards becoming general practitioners or specialists, exploring associated factors. Descriptive survey of 822 first to seventh year medical students at the University of Chile, School of Medicine. Desired activity to pursue (general practice or specialization) after graduation and general orientations within clinical practice were explored. Fifty three percent of students desired to enter a specialization program. Only 20% would work as a general practitioner (27% were still indecisive). Furthermore, a trend in early years of medical training towards an integral medicine is gradually reversed within later years. Seventh year students give significantly more importance to specialization than to integral medicine (p specialized medicine in the teaching environment. Most students prefer to enter a specialization program immediately after finishing medical school. Moreover, there is a social trend, at least within the teacher-attending environment, promoting not only the desire to specialize, but a pro-specialist culture.

    The aim of this study was to explore and compare the self-reported general and professional values in undergraduate student nurses and nurse educators in Lithuania. Contemporary nursing requires strong moral motivation and clear values as nurses confront many ethical dilemas in their practice. Students acquire essential values of the nursing profession through the appropriate role modelling of their educators. Nursing students seek to become capable in providing ethical and professional patient care while their educators attempt to model desired behaviours. A national cross-sectional comparative study was carried out in March 2011. Four-hundred eight respondents participated: 316 undergraduate nursing students and 92 nurse educators. A 57-item questionnaire was delivered to nursing programs at three universities and six colleges. Permission to conduct the study was granted by The Center on Bioethics. Student nurses and their educators rated the general value of altruism equally. Educators, in comparison with students, ranked honesty and intellectualism significantly higher and more often admired truth-telling in any circumstance. Students were more likely to avoid intellectual challenges in reading and placed lower importance on academic qualifications for career advancement. The professional nursing values of honesty, intellectualism and authority were ranked significantly higher by nurse educators than student nurses. The study revealed differences in self-reported general and professional values in undergraduate student nurses and nurse educators. The values of nurse educators were not always stronger than those of students. Positive relationships between particular general and professional values in both students and educators confirmed the link between professional and personal values. © 2017 John Wiley & Sons Ltd.

    Science educators have suggested many benefits that accrue from engaging students in experimental activities, therefore, experimental work has a long and distinctive role in chemistry curriculum since. The presented empirical study focuses on the valuation of effectiveness of different forms of experimental work - students' hands-on experimental work vs teacher's lecture demonstration - from the viewpoint of the quality of content knowledge acquisition and knowledge retention in teaching primary school chemistry. 106 primary school students (age 14-15 years) participated in the study. The data was collected via pre- and post- test protocol and two delayed post tests. Additionally 16 students selected from the sample were interviewed. The results indicate that students' content knowledge gained through teacher's demonstration of experiment is better and better knowledge retention takes place in comparison to students' knowledge gained through students' hands-on experimental work. However, most of the inteviewed students stated that they prefered conducting of experiments by themselves in comparison to observation of teacher's demonstration.

    Introduction Community-based longitudinal clinical placements for medical students are becoming more common globally. The perspective of supervising clinicians about their experiences and processes involved in maximising these training experiences has received less attention than that of students. Aims This paper explores the general practitioner (GP) supervisor perspective of positive training experiences with medical students undertaking urban community-based, longitudinal clinical placements in the early years of medical training. Methods Year 2 medical students spent a half-day per week in general practice for either 13 or 26 weeks. Transcribed semi-structured interviews from a convenience sample of participating GPs were thematically analysed by two researchers, using a general inductive approach. Results Identified themes related to the attributes of participating persons and organisations: GPs, students, patients, practices and their supporting institution; GPs' perceptions of student development; and triggers enhancing the experience. A model was developed to reflect these themes. Conclusions Training experiences were enhanced for GPs supervising medical students in early longitudinal clinical placements by the synergy of motivated students and keen teachers with support from patients, practice staff and academic institutions. We developed an explanatory model to better understand the mechanism of positive experiences. Understanding the interaction of factors enhancing teaching satisfaction is important for clinical disciplines wishing to maintain sustainable, high quality teaching.

    2010-03-01

    Logical reasoning skills of students enrolled in General Chemistry at the University of Puerto Rico in Río Piedras were measured using the Group Assessment of Logical Thinking (GALT) test. The results were used to determine the students' cognitive level (concrete, transitional, formal) as well as their level of performance by logical reasoning mode (mass/volume conservation, proportional reasoning, correlational reasoning, experimental variable control, probabilistic reasoning and combinatorial reasoning). This information was used to identify particular deficiencies and gender effects, and to determine which logical reasoning modes were the best predictors of student performance in the general chemistry course. Statistical tests to analyze the relation between (a) operational level and final grade in both semesters of the course; (b) GALT test results and performance in the ACS General Chemistry Examination; and (c) operational level and student approach (algorithmic or conceptual) towards a test question that may be answered correctly using either strategy, were also performed.

    The aim of this study was to assess the perceived benefits of video-mediated demonstrations in learning endodontics. Participants in the study were 75 third-year students enrolled in the undergraduate dentistry program at Karolinska Institute, Stockholm, Sweden. After the endodontic preclinical course, the students were introduced to the treatment protocol in the clinic by watching two live patient-demonstrated videos. The first video demonstrated how to communicate with the patient and perform diagnosis and root canal instrumentation. The second video illustrated how to perform bacterial sampling and root canal filling. After the students watched each video, a questionnaire was used to evaluate their opinions about various steps of the endodontic treatment protocol and the benefit of such educational material for their practice. Of the total 75 students, 72 completed the first questionnaire (96% response rate), and 65 completed the second questionnaire (87% response rate). The results showed that the students perceived high value in the video demonstrations related to treatment procedure. A statistically significant difference was observed between the perceived benefits of the first and second sessions in communication and treatment procedure (p<0.001). Further studies are needed to assess improvement in the design and delivery format for video demonstrations to enhance their effectiveness as a teaching modality for endodontics.

    The adolescence period of life comes along with changes and challenges in terms of physical and cognitive development. In this hectic period, many adolescents may suffer more from various risk factors such as low socioeconomic status, substance abuse, sexual abuse and teenage pregnancy. Findings indicate that such disadvantaged backgrounds of Malaysian adolescent students lead to failure or underachievement in their academic performance. This narrative review scrutinises how some of these students are able to demonstrate academic resilience, which is satisfactory performance in cognitive or academic tasks in spite of their disadvantaged backgrounds. The review stresses the need for developing a caregiving relationship model for at-risk adolescent students in Malaysia. Such a model would allow educators to meet the students' needs for enhancing thinking skills, counteracting risk factors and demonstrating academic resilience. PMID:25663734

    Electroconvulsive therapy (ECT) is safe and effective for the treatment of various psychiatric disorders. Despite being a well-known treatment method among health care professionals, lay people generally have a negative opinion of ECT. The present study aimed to examine knowledge of and attitudes toward ECT among medical students, psychology students, and the general public. Psychology students were included because they are among the important groups in mental health care in Turkey. A Likert-type questionnaire was administered to fifth-year medical students (n = 28), master of science and doctor of philosophy clinical psychology students (n = 35), and a sample of the general public (n = 26). The questionnaire included questions about the general principles of and indications for ECT, and sources of knowledge of and attitudes toward ECT. The medical students were the most knowledgeable about ECT, as expected. The medical students also had a more positive attitude toward ECT than the other 2 groups. More psychology students had negative attitudes on some aspects than general public sample, despite being more knowledgeable. Medical school theoretical and practical training in ECT played an important role in increasing the level of knowledge of and decreasing the prevalence of negative attitudes toward ECT among the medical students; similar training for psychology students is required to achieve similar results.

    Research has shown that the use of demonstrations and hands-on activities in the classroom enhances student learning. Students learn more and enjoy classes more when visual and active learning are incorporated into the lecture. Most college-aged students prefer visual modes of learning, while most instruction is conducted in a lecture, or auditory, format. The use of classroom demonstrations provides opportunities for incorporating visual and active learning into the classroom environment. However, while most instructors acknowledge the benefits of these teaching methods, they typically do not have the time and resources to develop and test such activities and to develop plans to incorporate them into their lectures. Members of the Excellence in Water Resources Education Task Committee of the Environmental and Water Resources Institute (EWRI) of the American Society of Civil Engineers (ASCE) have produced a publication that contains a collection of activities aimed to foster excellence in water resources and hydrology education and improve student learning of principles. The book contains forty-five demonstrations and activities that can be used in water-related classes with topics in fluid mechanics, hydraulics, surface water hydrology, groundwater hydrology, and water quality. We present examples of these activities, including topics such as conservation of momentum, buoyancy, Bernoulli's principle, drag force, pipe flow, watershed delineation, reservoir networks, head distribution in aquifers, and molecular diffusion in a porous medium. Unlike full laboratory exercises, these brief demonstrations and activities (most of which take less than fifteen minutes) can be easily incorporated into classroom lectures. For each demonstration, guidance for preparing and conducting the activity, along with a brief overview of the principles that are demonstrated, is provided. The target audience of the activities is undergraduate students, although the activities also may be

  17. The achievement impact of the inclusion model on the standardized test scores of general education students

    Science.gov (United States)

    Garrett-Rainey, Syrena

    The purpose of this study was to compare the achievement of general education students within regular education classes to the achievement of general education students in inclusion/co-teach classes to determine whether there was a significant difference in the achievement between the two groups. The school district's inclusion/co-teach model included ongoing professional development support for teachers and administrators. General education teachers, special education teachers, and teacher assistants collaborated to develop instructional strategies to provide additional remediation to help students to acquire the skills needed to master course content. This quantitative study reviewed the end-of course test (EoCT) scores of Grade 10 physical science and math students within an urban school district. It is not known whether general education students in an inclusive/co-teach science or math course will demonstrate a higher achievement on the EoCT in math or science than students not in an inclusive/co-teach classroom setting. In addition, this study sought to determine if students classified as low socioeconomic status benefited from participating in co-teaching classrooms as evidenced by standardized tests. Inferential statistics were used to determine whether there was a significant difference between the achievements of the treatment group (inclusion/co-teach) and the control group (non-inclusion/co-teach). The findings can be used to provide school districts with optional instructional strategies to implement in the diverse classroom setting in the modern classroom to increase academic performance on state standardized tests.

    2017-04-01

    Full Text Available To assess effectively the influence of peer discussion in understandingconcepts, and to evaluate if the conceptual understanding through Interactive Lecture Demonstrations (ILD and collaborative learning can be translated to actual situations, ten (10 questions on human and carts in motion were presented to 151 university students comprising mostly of science majors but of different year levels. Individual and group predictions were conducted to assess the students’ pre-conceptual understanding of motion graphs. During the ILD, real-time motion graphs were obtained and analysed after each demonstration and an assessment that integrates the ten situations into two scenarios was given to evaluate the conceptual understanding of the students. Collaborative learning produced a positive effect on the prediction scores of the students and the ILD with real-time measurement allowed the students to validate their prediction. However, when the given situations were incorporated to create a scenario, it posted a challenge to the students. The results of this activity identified the area where additional instruction and emphasis is necessary.

    2018-04-01

    Asthma is a potentially serious chronic respiratory disease impacting patients quality of life. Satisfactory control requires proper use of inhaled devices. This study assesses general medical residents and pharmacy students knowledge about proper use of inhaled asthma devices. We evaluated knowledge of 43 general practice students and 43 pharmacy students in Lille for three inhaler devices (metered-dose inhaler, Turbuhaler ® and Diskus ® ) during individual interviews. Students were assessed on 8 proper use criterias for each device. General practice and pharmacy students are unfamiliar with proper use of inhaler devices. However, pharmacy students get better average scores than general practice students for all devices included in this study: 6.3/8 respected criterias against 5/8 for metered-dose inhaler; 5.3/8 against 3.2/8 for Turbuhaler ® ; and 6/8 against 4.3/8 for Diskus ® . Pharmacy students more frequently perform a demonstration of proper use to patients when a device is first prescribed or when a prescription is renewed; general practice students more frequently ask patients themselves to perform a demonstration of proper use. Introducing trainings workshops for inhaler devices to pharmacy and general practice students appears appropriate in order to promote therapeutic patient education, to increase asthma control and better patients life quality.

  6. Water Hammer Simulations of MMH Propellant - New Capability Demonstration of the Generalized Fluid Flow Simulation Program

    2017-01-01

    Fluid Transient analysis is important for the design of spacecraft propulsion system to ensure structural stability of the system in the event of sudden closing or opening of the valve. Generalized Fluid System Simulation Program (GFSSP), a general purpose flow network code developed at NASA/MSFC is capable of simulating pressure surge due to sudden opening or closing of valve when thermodynamic properties of real fluid are available for the entire range of simulation. Specifically GFSSP needs an accurate representation of pressure-density relationship in order to predict pressure surge during a fluid transient. Unfortunately, the available thermodynamic property programs such as REFPROP, GASP or GASPAK does not provide the thermodynamic properties of Monomethylhydrazine (MMH). This paper will illustrate the process used for building a customized table of properties of state variables from available properties and speed of sound that is required by GFSSP for simulation. Good agreement was found between the simulations and measured data. This method can be adopted for modeling flow networks and systems with other fluids whose properties are not known in detail in order to obtain general technical insight. Rigorous code validation of this approach will be done and reported at a future date.

    Dissociated strabismus complex (DSC) is an enigmatic form of strabismus that includes dissociated vertical deviation (DVD) and dissociated horizontal deviation (DHD). We employed magnetic resonance imaging (MRI) to evaluate the extraocular muscles in DSC. We studied 5 patients with DSC and mean age of 25 years (range, 12-42 years), and 15 age-matched, orthotropic control subjects. All patients had DVD; 4 also had DHD. We employed high-resolution, surface coil MRI with thin, 2 mm slices and central target fixation. Volumes of the rectus and superior oblique muscles in the region 12 mm posterior to 4 mm anterior to the globe-optic nerve junction were measured in quasi-coronal planes in central gaze. Patients with DSC had no structural abnormalities of rectus muscles or rectus pulleys or the superior oblique muscle but exhibited modest, statistically significant increased volume of all rectus muscles ranging from 20% for medial rectus to 9% for lateral rectus (P muscles. DSC is associated with generalized rectus extraocular muscle hypertrophy in the absence of other orbital abnormalities.

  12. Teaching General Education Students How to Write Scientific Arguments Using Real Earth Data

    Kelly, G. J.; Prothero, W. A.

    2003-12-01

    Writing activities can improve student understanding of scientific content and processes. We have studied student writing to identify the challenges that students face in composing scientific arguments and to clarify features that constitute quality in scientific writing. We have applied argumentation analysis for the assessment of students' use of evidence in a general education oceanography course. Argumentation analysis refers to the systematic examination of ways that conclusions are supported with evidence. The student writers were supported by an interactive CD-ROM, "Our Dynamic Planet," which provided students with "point and click" access to real earth data and allowed them to solve many problems associated with plate tectonics. Plate boundary types (using quakes, volcanoes, elevation profiles, and heat flow) and plate motion can be determined (seafloor age, island ages/hot spots) with this technology. First, we discuss the structure of scientific argument and how this structure can be made accessible to undergraduate students. Second, we present examples of argumentation analysis applied to student writing. These examples demonstrate how use of large scale geological data sets can be used to support student writing. Third, we present results from a series of studies to show ways that students adhere to the genre conventions of geological writing through use of theoretical claims, multiple lines of evidence, and cohesive terms. These results, combined with our evidence-based orientation to instruction, formed the basis for modifications in the course instruction. These instructional modifications include providing detailed examples of data based observations and interpretations, heuristics for assessing other students' arguments, and quick write exercises with similar but simplified writing tasks. More information about the CD-ROM may be found at http://oceanography.geol.ucsb.edu/.

  13. Demonstrating the unit hydrograph and flow routing processes involving active student participation - a university lecture experiment

    2018-05-01

    The unit hydrograph (UH) has been one of the most widely employed hydrological modelling techniques to predict rainfall-runoff behaviour of hydrological catchments, and is still used to this day. Its concept is based on the idea that a unit of effective precipitation per time unit (e.g. mm h-1) will always lead to a specific catchment response in runoff. Given its relevance, the UH is an important topic that is addressed in most (engineering) hydrology courses at all academic levels. While the principles of the UH seem to be simple and easy to understand, teaching experiences in the past suggest strong difficulties in students' perception of the UH theory and application. In order to facilitate a deeper understanding of the theory and application of the UH for students, we developed a simple and cheap lecture theatre experiment which involved active student participation. The seating of the students in the lecture theatre represented the hydrological catchment in its size and form. A set of plastic balls, prepared with a piece of magnetic strip to be tacked to any white/black board, each represented a unit amount of effective precipitation. The balls are evenly distributed over the lecture theatre and routed by some given rules down the catchment to the catchment outlet, where the resulting hydrograph is monitored and illustrated at the black/white board. The experiment allowed an illustration of the underlying principles of the UH, including stationarity, linearity, and superposition of the generated runoff and subsequent routing. In addition, some variations of the experimental setup extended the UH concept to demonstrate the impact of elevation, different runoff regimes, and non-uniform precipitation events on the resulting hydrograph. In summary, our own experience in the classroom, a first set of student exams, as well as student feedback and formal evaluation suggest that the integration of such an experiment deepened the learning experience by active

    2016-10-01

    Recently, the inverted instruction methodologies are gaining attentions in higher educations by claiming that flipping the classroom engages more effectively students with the learning process. Besides, students' perceptions and emotions involved in their learning process must be assessed in order to gauge the usability of this relatively new instruction methodology, since it is vital in the educational formation. For this reason, this study intends to evaluate the students' perceptions and emotions when a flipped classroom setting is used as instruction methodology. This research was conducted in a general science course, sophomore of the Primary Education bachelor degree in the Training Teaching School of the University of Extremadura (Spain). The results show that the students have the overall positive perceptions to a flipped classroom setting. Particularly, over 80 % of them considered that the course was a valuable learning experience. They also found this course more interactive and were willing to have more courses following a flipped model. According to the students' emotions toward a flipped classroom course, the highest scores were given to the positive emotions, being fun and enthusiasm along with keyword frequency test. Then, the lowest scores were corresponded to negative emotions, being boredom and fear. Therefore, the students attending to a flipped course demonstrated to have more positive and less negative emotions. The results obtained in this study allow drawing a promising tendency about the students' perceptions and emotions toward the flipped classroom methodology and will contribute to fully frame this relatively new instruction methodology.

    Encouraging students at all grade levels to consider pursuing a career in Science, Technology, Engineering, and Mathematics (STEM) fields i s a national focus. In 2005, the Naval Surface Warfare Center, Dahlgren Division (NSWCDD), a Department of Defense laboratory located in Da hlgren, Virginia, began work on the Virginia Demonstration Project (VDP) with the goal of increasing more student interest in STEM educatio n and pursuing STEM careers. This goal continues as the program enters its sixth year. This project has been successful through the partici pation of NSWCDD's scientists and engineers who are trained as mentor s to work in local middle school classrooms throughout the school year, As an extension of the in-class activities, several STEM summer aca demies have been conducted at NSWCDD, These academies are supported by the Navy through the VDP and the STEM Learning Module Project. These projects are part of more extensive outreach efforts offered by the National Defense Education Program (NDEP), sponsored by the Director, Defense Research and Engineering. The focus of this paper is on the types of activities conducted at the summer academy, an overview of the academy planning process, and recommendations to help support a nati onal plan of integrating modeling and simulation-based engineering and science into all grade levels. based upon the lessons learned

    Literature suggests declining interest in General Surgery (GS) and other surgical specialties, with fewer Canadian medical residency applicants identifying a surgical specialty as their first choice. Although perceptions of surgical careers may begin before enrollment in clerkship, clerkship itself provides the most concentrated environment for perceptions to evolve. Most students develop perceptions about specialties during their clinical clerkships. This study examines the immediate impact of GS clerkship on student attitudes toward GS as a career, and on preferences towards GS compared with other specialties. A pre-post design involved 61 McMaster clinical clerks. Two instruments were used to collect data from students over the course of clerkship (2008-2009). Paired comparison (PC) compared ranking of career choices before and after clerkship. Semantic differential (SD) measured attitudes toward GS and variables that may have affected attitudes before and after clerkship. Analyses used SPSS 16.0 (SPSS Inc., Chicago, IL). Clerks ranked preferences for GS changed substantially after clerkship, moving from the 10th to the 5th position compared with other specialties. Ranks of surgical subspecialties also changed, though GS demonstrated the largest improvement. SD results were consistent with PC, showing improved attitudes after rotation, with differences both statistically and practically significant (t = 3.81, p staff (including attending surgeons and nurses), ensure that teaching hospital staff provide a positive experience for clerks, and should provide opportunities to learn basic technical skills during GS clerkship.

    Although various studies have assessed performance of athletes on the Functional Movement Screen (FMS) and the Y Balance Test (YBT), no study to date has directly evaluated a comparison of performance between athletes and members of the general population. Thus, to better understand the application of the FMS and the YBT to general college students, this study examined whether or not general college students performed similarly to student-athletes on the FMS (composite and movement pattern scores) and the YBT (composite and reach directions). This study evaluated 167 Division I student-athletes and 103 general college students from the same university on the FMS and the YBT. No difference was found in FMS composite scores between student-athletes and general college students. For FMS movement patterns, female student-athletes scored higher than general college students in the deep squat. No difference was found for men in any FMS movement pattern. Female student-athletes scored higher than female general college students in YBT composite scores; no difference was found for men in YBT composite scores. In analysis of YBT reach directions, female student-athletes scored higher than female general college students in all reach directions, whereas no difference was found in men. Existing research on the FMS composite score in athletic populations may apply to a general college population for the purposes of preparticipation screening, injury prediction, etc. Existing research on the YBT in male athletic populations is expected to apply equally to general college males for the purposes of preparticipation screening, injury prediction, etc.

  3. Using discrepant events in science demonstrations to promote student engagement in scientific investigations: An action research study

    Science.gov (United States)

    Mancuso, Vincent J.

    Students' scientific investigations have been identified in national standards and related reform documents as a critical component of students' learning experiences in school, yet it is not easy to implement them in science classrooms. Could science demonstrations help science teachers put this recommendation into practice? While demonstrations are a common practice in the science classroom and research has documented some positive effects in terms of student motivation and engagement from their use, the literature also shows that, as traditionally presented, science demonstrations do not always achieve their intended outcomes. This, in turn, suggested the value of investigating what design elements of demonstrations could be used to promote specific instructional goals. Employing action research as a methodology, the proposed study was developed to explore how science demonstrations can be designed so as to most effectively promote student engagement in scientific investigations. More specifically, I was interested in examining the effects of using a discrepant event as part of the demonstration, as a way to create cognitive conflict and, thus, increase interest and engagement. I also investigated the relative merit of the well-researched POE (Predict, Observe, Explain) design versus employing demonstrations that appear to the student to be unplanned (what I will refer to as NOE, or a Naturally Occurring Experience). This study was informed by Constructivism, Situated Cognition and Conceptual Change as theoretical frameworks. The project included the design, implementation and study of an intervention consisting of three instructional units designed to support students' learning of the concepts of density, molecular arrangement of gas particles, and cohesion, respectively. In each of these units, lasting a total of two 80-minute class periods, students were asked to design and conduct an investigation to gain a better understanding of the concept under study. In

    Full Text Available The inappropriate disposal of infectious waste generates occupational and environmental risks, representing the main cause of accidents with biological material. The aim of the present study was to verify the knowledge and the practice regarding the disposal of infectious waste among nursing and medical undergraduate students at a public university in the state of Goiás. Data were collected with the application of a questionnaire. The respondent students were observed in their practice and data were recorded in a checklist. Nursing students presented greater knowledge than medical students on the disposal of contaminated gloves (x²; p<0.001, as well as on the disposal of sharp cutting instruments (p=0.001. Contaminated gloves were disposed of into bags for common waste both by the nursing and the medical students. Results evidenced that the knowledge of students on the disposal of infectious waste was poor and insufficient to ensure its application to practice.

    General practice is under-represented in student career choices. This study aimed to identify and explore factors that influence the attitudes of final year medical students to general practice as a career. This qualitative study used semi-structured interviews of focus groups of final year undergraduate medical students at the University of Otago, Christchurch, New Zealand. Thematic analysis and grounded theory were used to interpret the data. General practitioners (GPs) play a key role in influencing medical students' attitudes to general practice as a career. Students identified their general practice placement during medical school training and personal contact with their own GP as principal factors. The media portrayal of general practice and the attitudes of friends and family were also influential. Students were positively influenced when they were made to feel part of the team, involved with consultations, allowed to carry out practical procedures under supervision, and witnessed what they perceived as good medical practice during clinical placements. Positive experiences often occurred later in training, when students felt more confident of their clinical abilities. While students reported occasional negative comments about general practice by some hospital doctors, these had a lesser role in influencing their perceptions of general practice compared with their own experiences, both as students and patients. GPs have a strong influence, positively and negatively, on the attitudes of medical students to general practice as a career. Effective influences include being made to feel welcome, involved, valued, and given legitimate roles during clinical placements.

    Students in general and special education experience bullying. However, few empirical investigations have examined involvement in bullying along the bully/victim continuum (i.e., as a bully, victim, or bully-victim) among students with disabilities. A total of 816 students, ages 9 to 16, participated in the present study. From this total sample 686 were not receiving special education services (categorized as "no disability"), and 130 were receiving special education services (categorized as "observable disability," "non-observable disability," and "behavioral disability"). Data on students' involvement in bullying, office referrals, and prosocial behavior were collected. Results indicated that students with behavioral disorders and those with observable disabilities reported bullying others more and being victimized more than their general education counterparts. Students with behavioral disorders also had significantly more office referrals than students in general education. Seventh graders in general education reported more bullying behavior than sixth graders and ninth grades in general education. Fifth graders in general education reported more victimization than students in all other grades in general education. However, the grade differences were not significant for students in special education. No gender differences on bullying and victimization were found. Students with disabilities reported less engagement in prosocial behaviors than their general education peers. Implications for bullying prevention and intervention across both general and special education are discussed. Copyright © 2012. Published by Elsevier Ltd.

    Full Text Available Introduction: Quantitative and qualitative enhancement of educational activities is an essential issue. Learners’ cooperation in the teaching process in order to increase teaching effectiveness and promotion is considered significant. The aim of the present study was to determine the effect of establishment of student working group on the teaching general embryology course to medical students.Methods: Ten students (1% of medical embryology course were selected to analyze the topics to be taught before each session according to lesson plan, and observe the whole teaching process during lesson presentation. Then, having asked the other students’ viewpoints and discussing with one another, they provided the teacher with a written report on the strengths and weaknesses of the teaching and its problems. The teacher analyzed the problems proposed by the working group to improve teaching process in the next session. At the end of the semester, a questionnaire was administered to all the participants. Data were analyzed using descriptive statistics.Results: The mean of students’ scores was 74.26%. The most important findings obtained in this study included positive role of film projection in teaching the materials (95.34%, significance of presentation of various pictures from different books (88.4%, changing students’ attitude toward application of embryology in different diseases (86%, and repetition of previous session’s pictures (83.75%. The weak points mentioned, however, were physical problems of the classroom and deficiency of audio visual equipment.Conclusion: Student working group has a positive impact on the teaching medical general embryology.

    The purpose of this study was to evaluate a model for considering general and specific elements of student experience in a gateway course in undergraduate Financial Accounting in a large university on the East Coast, USA. Specifically, the study evaluated a bifactor analytic strategy including a general factor of student classroom experience, conceptualized as student engagement as rooted in flow theory, as well as factors representing specific dimensions of experience. The study further evaluated the association between these general and specific factors and both student classroom practices and educational outcomes. The sample of students ( N = 407) in two cohorts of the undergraduate financial accounting course participated in the Experience Sampling Method (ESM) measuring students' classroom practices, perceptions, engagement, and perceived learning throughout the one-semester course. Course grade information was also collected. Results showed that a two-level bifactor model fit the data better than two traditional (i.e., non-bifactor) models and also avoided significant multicollinearity of the traditional models. In addition to student engagement (general factor), specific dimensions of classroom experience in the bifactor model at the within-student level included intrinsic motivation, academic intensity, salience, and classroom self-esteem. At the between-student level, specific aspects included work orientation, learning orientation, classroom self-esteem, and disengagement. Multilevel Structural Equation Modeling (MSEM) demonstrated that sitting in the front of the classroom (compared to the sitting in the back), taking notes, active listening, and working on problems during class had a positive effect on within-student variation in student engagement and attention. Engagement, in turn, predicted perceived learning. With respect to between-student effects, the tendency to sit in front seats had a significant effect on student engagement, which in turn had

    We have investigated whether and how a categorization of responses to questions on linear distance-time graphs, based on a study of Irish students enrolled in an algebra-based course, could be adopted and adapted to responses from students enrolled in calculus-based physics courses at universities in Flanders, Belgium (KU Leuven) and the Basque Country, Spain (University of the Basque Country). We discuss how we adapted the categorization to accommodate a much more diverse student cohort and explain how the prior knowledge of students may account for many differences in the prevalence of approaches and success rates. Although calculus-based physics students make fewer mistakes than algebra-based physics students, they encounter similar difficulties that are often related to incorrectly dividing two coordinates. We verified that a qualitative understanding of kinematics is an important but not sufficient condition for students to determine a correct value for the speed. When comparing responses to questions on linear distance-time graphs with responses to isomorphic questions on linear water level versus time graphs, we observed that the context of a question influences the approach students use. Neither qualitative understanding nor an ability to find the slope of a context-free graph proved to be a reliable predictor for the approach students use when they determine the instantaneous speed.

  20. A Comparative Study of Argument from Primordial Nature and Argument from General Consensus on the Demonstration of Existence of God

    2014-08-01

    Full Text Available Historical evidences suggest that human beings have been always in search of God in some form. Some believe that man is born with this divine sense. This ubiquitous quality of human beings is called primordial nature (fitrah. Many scholars have tried to demonstrate the existence of God through this shared quality of human individuals. In Islamic thought this latter intellectual effort has been designated as "argument from primordial nature" and in western theological and philosophical thought it is known as "argument from general consensus". Although these arguments have some differences in their general settings and attitudes; but they both resort to human general divine attitude to demonstrate the existence of God. In this essay we have sought to propound the views of those scholars who have dealt with this argument at length. Reflecting on the general form of the expositions shows that the expositions of argument from primordial nature and argument from general consensus cannot demonstrate the existence of God without basing themselves on the principle of causation or human existential poverty. Via comparative assessment of these two arguments we have turned to the critiques which have been leveled against them and laid bare their similarities and differences. Of course there are some differences between the argument from primordial nature in Islam and the argument from general consensus in west. This essay seeks to assay the key expositions which have been offered of these arguments in Islamic and western philosophies. It seems that among Moslem philosophers, Mulla Sadra from the early generation, Allameh Tabtabaei, Imam Khomeini, Jawadi Amuli and Mutahari from later generation, have paid more attention to this argument. Among western scholars one can mention William James, Charles Hodge, James Joyce, Paul Tillich and Seneca who have made more direct remarks on this argument. John Locke is also against this argument. This is why we have

    Full Text Available Safety awareness in the laboratory is essential to reduce occupational risks. This study was conducted to determine the students’ safety awareness in a Physics laboratory. This study determined the student perception towards safety awareness by factors of gender and college from which students are enrolled. A sum of 324 students enrolled in Physics10 (Mechanics and Heat and Physics11 (Electricity and Magnetism in the Mindanao University of Science and Technology (MUST were randomly selected as survey respondents. A modified survey questionnaire was used as research instrument. The results show that the students had positive level of safety awareness and perceived positively on the preventive measures to reduce laboratory risk. Further, regardless of gender students enrolled in Physics 10 were more positively aware towards safety awareness than students enrolled in Physics 11. Similarly, a variation among the students perception towards safety awareness from the College of Engineering and Architecture (CEA and College of Industrial and Information Technology (CIIT occurred. Overall, present findings indicate a need to introduce laboratory safety awareness in Physics classes.

    Education policies encourage inclusion of students with mild-intellectual disability (mild-ID) in community/school life. However, such policies potentially increase exposure to substance use. This article examines tobacco, alcohol and cannabis use among French students enrolled in special units for students with disabilities (ULIS) at mainstream junior high schools compared to those of general population of the equivalent age; and explores factors associated with substance use among ULIS students, known to present mostly mild-ID. In 2014, a questionnaire adapted from the international HBSC/WHO study was administered to 700 ULIS students (mean-age 14.2). Comparative data were gathered from 7023 junior high-school students (mean-age 13.6) in the general population. Among students <14 years-old, tobacco and alcohol use rates were similar between ULIS and general population. For students ≥14, alcohol use remained comparable, while tobacco and cannabis use were higher in general population. Among ULIS students, low perceived health/life satisfaction, divorced/separated parents and high perceived academic demands were associated with tobacco use. Bullying, not liking school very much and attending schools outside a deprived area were associated with alcohol use. Having had sexual intercourse and not perceiving one's health as excellent were associated with cannabis use. Having dated was associated with using all three substances.

    Australia will continue to face a general practitioner (GP) shortage unless a significant number of medical students make general practice their chosen career. Perceptions regarding general practice may influence career choices. Thus this study investigated what Australian medical students perceived to be the advantages and disadvantages of pursuing a career in general practice via an anonymous online survey. Fifty-one students indicated general practice to be their first ranked career preference, 200 indicated a career other than general practice, and 106 were undecided. Two-hundred and two students reported having been on a GP placement, whereas 88 students had not. Flexibility, continuity of patient care and work-life balance were the three most common stated advantages to pursuing a career in general practice whereas general practice being boring, poorly paid, and of low prestige were the three most common disadvantages stated. Some disadvantages stated by those with a non-GP preference were not stated by those with a GP preference (e.g. lack of procedural skills, lack of career advancement opportunities). Students with more than 80 h of GP placement experience were more likely to list the advantages of work-life balance and a diversity of problems/illnesses/patients than those with no placement experience but were also more likely to list the disadvantage of low prestige. Negative stereotypes regarding general practice continue to exist which may influence students' career choices.

    Dodd, Matthew Robert

    General education and Special Education students from three high schools in Rutherford County were sampled to determine the effect on their academic achievement on the Tennessee Biology I Gateway Exam in Inclusion classrooms. Each student's predicted and actual Gateway Exam scores from the academic year 2006--2007 were used to determine the effect the student's classroom had on his academic achievement. Independent variables used in the study were gender, ethnicity, socioeconomic level, grade point average, type of classroom (general or Inclusion), and type student (General Education or Special Education). The statistical tests used in this study were a t-test and a Mann--Whitney U Test. From this study, the effect of the Inclusion classroom on general education students was not significant statistically. Although the Inclusion classroom allows the special education student to succeed in the classroom, the effect on general education students is negligible. This study also provided statistical data that the Inclusion classroom did not improve the special education students' academic performances on the Gateway Exam. Students in a general education classroom with a GPA above 3.000 and those from a household without a low socioeconomic status performed at a statistically different level in this study.

    Alcohol use is reported in university students with discrepancy between countries. The study objectives were to assess prevalence and associated factors of alcohol consumption among university students in Germany and China. Data used were from 1853 Chinese and 3306 German university students. Alcohol consumption frequency was measured by a question "How often did you drink alcohol in the last three months?" with six possible responses, which were later collapsed into three categories of "At least once a week", "Less than once a week" and "Never". Problem drinking was measured by the CAGE test and defined as a CAGE score of two or more (four as the maximum). Simple and multivariable logistic regressions were used for association analyses. German students reported more often "At least once a week" drinking (59.8 vs. 9.0 %). Among Germans, women drank less often "At least once a week" (OR = 0.40, 0.30-0.53). Among Chinese, a higher BMI was associated with drinking "At least once a week" (OR = 1.09, 1.02-1.18). Age revealed a positive association with "At least once a week" drinking in Chinese (1.33, 1.21-1.46) but a negative association in Germans (OR = 0.97, 0.94-0.99). Having a father with high educational level was positively related to "At least once a week" drinking in both countries (OR = 4.25, 2.67-6.78 for Chinese; OR = 1.32, 1.01-1.72 for Germans). Doing less than once a week physical exercise was negatively associated with "At least once a week" drinking in Chinese and German students (OR = 0.27, 0.15-0.48 for Chinese; OR = 0.69, 0.49-0.96 for Germans). Among the German students, 20.3 % reported problem drinking. Being a female (OR = 0.32, 0.26-0.40) and performing less than once a week physical activity (OR = 0.73, 0.56-0.95) were negatively associated with problem drinking, while having a father with high educational level (OR = 1.32, 1.09-1.60) and experiencing higher level of perceived stress (OR = 1.08, 1

  7. Earth's Earliest Ecosystems in the C: The Use of Microbial Mats to Demonstrate General Principles of Scientific Inquiry and Microbial Ecology

    Bebout, Brad M.; Bucaria, Robin

    2006-01-01

    Microbial mats are living examples of the most ancient biological communities on Earth. As Earth's earliest ecosystems, they are centrally important to understanding the history of life on our planet and are useful models for the search for life elsewhere. As relatively compact (but complete) ecosystems, microbial mats are also extremely useful for educational activities. Mats may be used to demonstrate a wide variety of concepts in general and microbial ecology, including the biogeochemical cycling of elements, photosynthesis and respiration, and the origin of the Earth's present oxygen containing atmosphere. Microbial mats can be found in a number of common environments accessible to teachers, and laboratory microbial mats can be constructed using materials purchased from biological supply houses. With funding from NASA's Exobiology program, we have developed curriculum and web-based activities centered on the use of microbial mats as tools for demonstrating general principles in ecology, and the scientific process. Our web site (http://microbes.arc.nasa.gov) includes reference materials, lesson plans, and a "Web Lab", featuring living mats maintained in a mini-aquarium. The site also provides information as to how research on microbial mats supports NASA's goals, and various NASA missions. A photo gallery contains images of mats, microscopic views of the organisms that form them, and our own research activities. An animated educational video on the web site uses computer graphic and video microscopy to take students on a journey into a microbial mat. These activities are targeted to a middle school audience and are aligned with the National Science Standards.

  8. Audit and feedback by medical students to improve the preventive care practices of general practice supervisors.

    Gilkes, Lucy A; Liira, Helena; Emery, Jon

    Medical students benefit from their contact with clinicians and patients in the clinical setting. However, little is known about whether patients and clinicians also benefit from medical students. We developed an audit and feedback intervention activity to be delivered by medical students to their general practice supervisors. We tested whether the repeated cycle of audit had an effect on the preventive care practices of general practitioners (GPs). The students performed an audit on topics of preventive medicine and gave feedback to their supervisors. Each supervisor in the study had more than one student performing the audit over the academic year. After repetitive cycles of audit and feedback, the recording of social history items by GPs improved. For example, recording alcohol history increased from 24% to 36%. This study shows that medical students can be effective auditors, and their repeated audits may improve their general practice supervisors' recording of some aspects of social history.

  9. Problematizing a general physics class: Understanding student engagement

    Science.gov (United States)

    Spaid, Mark Randall

    This research paper describes the problems in democratizing a high school physics course and the disparate engagement students during class activities that promote scientific inquiry. Results from the Learning Orientation Questionnaire (Martinez, 2000) guide the participant observations and semi-formal interviews. Approximately 60% of the participants self-report a "resistant" or "conforming" approach to learning science; they expect to receive science knowledge from the teacher, and their engagement is influenced by affective and conative factors. These surface learners exhibit second order thinking (Kegan, 1994), do not understand abstract science concepts, and learn best from structured inquiry. To sustain engagement, conforming learners require motivational and instructional discourse from their teacher and peers. Resisting learners do not value learning and do not engage in most science class activities. The "performing" learners are able to deal with abstractions and can see relationships between lessons and activities, but they do not usually self-reflect or think critically (they are between Kegan's second order and third order thinking). They may select a deeper learning strategy if they value the knowledge for a future goal; however, they are oriented toward assessment and rely on the science teacher as an authority. They are influenced by affective and conative factors during structured and guided inquiry-based teaching, and benefit from motivational discourse and sustain engagement if they are interested in the topic. The transforming learners are more independent, self-assessing and self-directed. These students are third order thinkers (Kegan, 1994) who hold a sophisticated epistemology that includes critical thinking and reflection. These students select deep learning strategies without regard to affective and conative factors. They value instructional discourse from the teacher, but prefer less structured inquiry activities. Although specific

    Students recruited from psychology undergraduate university populations are commonly used in psychology research, including gambling studies. However, the extent to which the use of this subpopulation produces findings that can be extrapolated to other groups is questionable. The present study was designed to compare results from university-recruited psychology student gamblers to those obtained from a sample of gamblers recruited from the general population that also included students. An online survey measuring gambling behavior and Internet gambling, attitudes and knowledge about gambling and problem gambling severity was posted on websites accessed by gamblers. Participants were recruited from two sources, a psychology undergraduate university population (n = 461) and online websites (n = 4,801). Results showed university-recruited students differed significantly from both adults and students recruited from the general population in respect to demographic variables and gambling behavior. Psychology undergraduate students were younger, more likely to be female, and had lower incomes. When relevant demographic variables were controlled, psychology undergraduate students were found to gamble less frequently, at different times, and to be at lower-risk for gambling-related problems, but had more irrational beliefs and more negative attitudes towards gambling than gamblers recruited from the general population. Results suggest that caution should be used in extrapolating findings from research using university-recruited psychology student gamblers to wide community populations due to differences related to gambling thoughts, attitudes and behaviors.

    In Germany, there is a shortage of young physicians in several specialties, the situation of general practitioners (GP) being especially precarious. The factors influencing the career choice of German medical students are poorly understood. This study aims to identify factors influencing medical students' specialty choice laying a special focus on general practice. The study was designed as a cross-sectional survey. In 2010, students at the five medical schools in the federal state of Baden-Wuerttemberg (Germany) filled out an online-questionnaire. On 27 items with 5-point Likert scales, the students rated the importance of specified individual and occupational aspects. Furthermore, students were asked to assign their intended medical specialty. 1,299 students participated in the survey. Thereof, 1,114 students stated a current choice for a specialty, with 708 students choosing a career in one of the following 6 specialties: internal medicine, surgery, gynaecology and obstetrics, paediatrics, anaesthetics and general practice. Overall, individual aspects ('Personal ambition', 'Future perspective', 'Work-life balance') were rated as more important than occupational aspects (i.e. 'Variety in job', 'Job-related ambition') for career choice. For students favouring a career as a GP individual aspects and the factor 'Patient orientation' among the occupational aspects were significantly more important and 'Job-related ambition' less important compared to students with other specialty choices. This study confirms that future GPs differ from students intending to choose other specialties particularly in terms of patient-orientation and individual aspects such as personal ambition, future perspective and work-life balance. Improving job-conditions in terms of family compatibility and work-life balance could help to increase the attractiveness of general practice. Due to the shortage of GPs those factors should be made explicit at an early stage at medical school to increase

    Advancing nuclear energy and radiation technology to drive the country forward should be based on the understanding and acceptance of the public. Korea has provided numerous types of information to increase public acceptance of nuclear energy, but it has been difficult to change adults’ perceptions and increase their acceptance of nuclear energy. As a result, social costs are rising. After a pilot program of 13 classes on understanding nuclear energy and radiation offered to elementary school students, who were expected to easily change their perceptions and to experience a relatively greater educational effect, this study analyzed changes to knowledge, attitudes, and behaviors regarding nuclear energy. In addition, this program was the first curriculum of its kind used as a step to lay the groundwork for offering it nationally in the free semester system. Therefore, the study analyzed its appropriateness to educational purposes. A lack of research and practice on communication strategies could be responsible for the situation in Korea of low support for nuclear energy because Korea does not have public understanding even though it is a nuclear energy exporter. If Korea implemented strategic communications from this point, such efforts could reduce unnecessary social costs

    ISAAC Infrared Spectroscopy to Analyse the middle Atmosphere Composition — was a student experiment launched from SSC's Esrange Space Centre, Sweden, on 29th May 2014, on board the sounding rocket REXUS 15 in the frame of the REXUS/BEXUS programme. The main focus of the experiment was to implement an ejection system for two large Free Falling Units (FFUs) (240 mm x 80 mm) to be ejected from a spinning rocket into a predefined direction. The system design relied on a spring-based ejection system. Sun and angular rate sensors were used to control and time the ejection. The flight data includes telemetry from the Rocket Mounted Unit (RMU), received and saved during flight, as well as video footage from the GoPro camera mounted inside the RMU and recovered after the flight. The FFUs' direction, speed and spin frequency as well as the rocket spin frequency were determined by analyzing the video footage. The FFU-Rocket-Sun angles were 64.3° and 104.3°, within the required margins of 90°+45°. The FFU speeds were 3.98 mIs and 3.74 mIs, lower than the expected 5± 1 mIs. The FFUs' spin frequencies were 1 .38 Hz and 1 .60 Hz, approximately half the rocket's spin frequency. The rocket spin rate slightly changed from 3. 163 Hz before the ejection to 3.1 17 Hz after the ejection of the two FFUs. The angular rate, sun sensor data and temperature on the inside of the rocket module skin were also recorded. The experiment design and results of the data analysis are presented in this paper.

    2015-01-01

    Background Health care is increasingly provided in general practice. To meet this demand, the English Department of Health recommends that 50% of all medical students should train for general practice after qualification. Currently 19% of medical students express general practice as their first career choice. Undergraduate exposure to general practice positively influences future career choice. Appropriate undergraduate exposure to general practice is therefore highly relevant to workforce planning Aim This study seeks to quantify current exposure of medical students to general practice and compare it with past provision and also with postgraduate provision. Design and setting A cross-sectional questionnaire in the UK. Method A questionnaire regarding provision of undergraduate teaching was sent to the general practice teaching leads in all UK medical schools. Information was gathered on the amount of undergraduate teaching, how this was supported financially, and whether there was an integrated department of general practice. The data were then compared with results from previous studies of teaching provision. The provision of postgraduate teaching in general practice was also examined. Results General practice teaching for medical students increased from teaching in 1968 to 13.0% by 2008; since then, the percentage has plateaued. The total amount of general practice teaching per student has fallen by 2 weeks since 2002. Medical schools providing financial data delivered 14.6% of the clinical curriculum and received 7.1% of clinical teaching funding. The number of departments of general practice has halved since 2002. Provision of postgraduate teaching has tripled since 2000. Conclusion Current levels of undergraduate teaching in general practice are too low to fulfil future workforce requirements and may be falling. Financial support for current teaching is disproportionately low and the mechanism counterproductive. Central intervention may be required to solve

    One approach to facilitating student interactions with patient pathways at Keele University School of Medicine, England, is the placement of medical students for 25% of their clinical placement time in general practices. The largest component is a 15-week 'student attachment' in primary care during the final year, which required the development of a new network of teaching practices in a rural district of England about 90 km (60 mi) from the main campus in North Staffordshire. The new accommodation and education hub was established in 2011-2012 to enable students to become immersed in those communities and learn about medical practice within a rural and remote context. Objectives were to evaluate the rural teaching from the perspectives of four groups: patients, general practice tutors, community hospital staff and students. Learning outcomes (as measured by objective structured clinical examinations) of students learning in rural practices in the final year were compared with those in other practices. Data were gathered from a variety of sources. Students' scores in cohort-wide clinical assessment were compared with those in other locations. Semi-structured interviews were conducted with general practice tutors and community hospital staff. Serial focus groups explored the perceptions of the students, and questionnaires were used to gather the views of patients. Patients reported positive experiences of students in their consultations, with 97% expressing willingness to see students. The majority of patients considered that teaching in general practice was a good thing. They also expressed altruistic ideas about facilitating learning. The tutors were enthusiastic and perceived that teaching had positive impacts on their practices despite negative effects on their workload. The community hospital staff welcomed students and expressed altruistic ideas about helping them learn. There was no significant difference between the rurally placed students' objective

    The aim of the study was to investigate medical students' views on general practice based on their experiences in training, and to find out whether there were certain views associated with the intention to become a GP. A questionnaire, based on our earlier studies about GP working behaviour, was handed out to medical students in terms 1, 3, 5, 7, 10 and 11 of undergraduate studies in Gothenburg, Sweden. The analysis comprised statistical descriptions and comparisons. The students regarded general practice positively. They found the work environment good, the GP's awareness of patients' living conditions necessary, and that GP work requires medical breadth. The status of the GP in the medical profession was not considered high. One-fourth of the students strongly agreed with the possibility of a future as a GP. This attitude was statistically associated with support to the statements that general practice offers a good work environment and should be a major component in undergraduate training. Students with a negative attitude to working as GPs were also negative to having a major component of general practice in undergraduate training. Medical students with a positive stated attitude towards becoming GPs support changes in undergraduate training to include more general practice. The risk of increasing a negative attitude should be considered when changes are discussed.

    Full Text Available The aim of the publication is to demonstrate the implementation of general methodological principles of optional elementary school online foreign languages learning on an example of a virtual course for students of the second and third grades.Methods. The methods involve pedagogical modeling and projecting; the experience of foreign and Russian methodists, teachers and researchers is analysed, generalized and adjusted to the modern realias.Results and scientific novelty. On the basis of the requirements of the state educational standard and interest of pupils in computer games, the author’s technique of the combined facultative educational activities integrated to training in English at elementary school is developed. Online training in the form of games (additional to the major classroom activities gives a possibility of the choice of tasks interesting to children, studying the material at optimum comfortable and individual speed; it is possible to perform the tasks at home excluding the stressful situations that are specific to school examination, and allows pupils to master most effectively personal, metasubject and object competences. In general context of quality improvement of the general education, the modernization of educational process assumes not only justification of its new maintenance, but also restructuring of scientific and methodical support which has to meet essential needs of teachers and pupils, to facilitate access to necessary specific information. The lack of methodical base of creation of electronic distance resources for foreign-language education of younger school students has motivated the author to create own methodical concept of online training taking into account age of pupils. The complex of the general methodical principles is thoroughly considered; based on the general methodical principles, the proposed modular technique of the organization of an online class is created and implemented.

    Few studies have systematically explored factors affecting medical students' general practice career choice. We conducted a nationwide multicenter survey (Japan MEdical Career of Students: JMECS) to examine factors associated with students' general practice career aspirations in Japan, where it has been decided that general practice will be officially acknowledged as a new discipline. From April to December 2015, we distributed a 21-item questionnaire to final year medical students in 17 medical schools. The survey asked students about their top three career preferences from 19 specialty fields, their demographics and their career priorities. Multivariable logistic regression was used to determine the effect of each item. A total of 1264 responses were included in the analyses. The top three specialty choice were internal medicine: 833 (65.9%), general practice: 408 (32.3%), and pediatrics: 372 (29.4%). Among demographic factors, "plan to inherit other's practice" positively associated with choosing general practice, whereas "having physician parent" had negative correlation. After controlling for potential confounders, students who ranked the following items as highly important were more likely to choose general practice: "clinical diagnostic reasoning (adjusted odds ratio (aOR): 1.65, 95% CI 1.40-1.94)", "community-oriented practice (aOR: 1.33, 95% CI 1.13-1.57)", and" involvement in preventive medicine (aOR: 1.18, 95% CI 1.01-1.38)". On the contrary, "acute care rather than chronic care", "mastering advanced procedures", and "depth rather than breadth of practice" were less likely to be associated with general practice aspiration. Our nationwide multicenter survey found several features associated with general practice career aspirations: clinical diagnostic reasoning; community-oriented practice; and preventive medicine. These results can be fundamental to future research and the development of recruitment strategies.

  5. Telescopic Topics: The Impact of Student-Created Podcasts in a Large, General Education Course

    Kraal, E. R.

    2014-12-01

    Large, general education courses are important to the geoscience community. These courses serve as valuable recruiting tools for future geoscience majors because over 55% of geoscience students select their major in the first two years of college (Wilson, 2013). These courses can have many challenges such as large class sizes, limited (or no) laboratory time and facilities, little financial resource support, non-permanent faculty, and a variety of student abilities and needs. High impact practices, such as writing courses, student research, and community service can be difficult to integrate into large, non-major courses. Student-produced audio (e. g. podcasts) provide one approach to providing high impact practices within these courses. Other researchers have found student produced audio to be effective at transmitting content, integrating place based experiences, and building community connections within the students. Here I present the implementation of student-created audio within a large (100+), general education course (AST 30 - Mission to the Planets) over the last 4 years called 'Telescopic Topics.' Activities scaffold the students through the semester where they select a topic on planetary science, work with the science reference librarian, visit the writing center, and record their podcast at campus student radio station. The top podcasts are then aired on the campus radio station during the news broadcasts through a rotating series. Surveys of student experiences find that student find the activity valuable and engaging. Students reported feeling less intimidated by the science content and more connected to the subject matter. In addition, it provides many of them with their first introduction to and use of the university library and associated campus resources.

    Full Text Available It is generally accepted that the use of iPad enhances students’ engagement in the classroom. However, assessing the benefits of using iPad in teaching laboratory sessions have seen less attention, due to the hands-on nature of these courses. To do this assessment, iPad was applied in teaching two pilot sessions of the General Chemistry Lab, and students’ evaluation was compared to that of other students in sections taught by conventional teaching techniques. The evaluation was based on the students’ assessment of their achievements in meeting the main course outcomes, which indicated that the students in the classes taught using iPad showed more satisfaction with the course, and believed that they have better achieved the outcomes of the course compared to the conventional classes. Furthermore, the comparison process included the overall students’ quantitative performance, which showed insignificant difference between the two classes, with slightly better performance of students in normal classes in quizzes, whereas final exam marks were almost the same for both the iPad piloted students and conventional class students. The differences in quizzes results were attributed to the normal variation in the students’ academic merits. In addition, the piloted students were asked about their experience of using iPad in class and their satisfaction by using different iPad Apps. The feedback was collected and analysed, and the results showed that the students generally enjoyed using iPad in the class and appreciated all Apps.

    Full Text Available The assessment of student’s clinical competence is of paramount importance, and there are several means of evaluating student performance in medical examinations. The OSCE is an approach to student assessment in which aspects of clinical competence are evaluated in a comprehensive, consistent and structured manner with close attention to the objectivity of the process. The faculty of general medicine in collaboration with other clinical departments, Mamata Medical College, Khammam first implemented the objective structured clinical examination (OSCE in the final MBBS Part-II examination during the internal assessment examination for the 2011-2012 academic years. The study was set out to explore student acceptance of the OSCE as part of an evaluation of final MBBS students. A self-administered questionnaire was completed by successive groups of students immediately after the OSCE. Main outcome measures were student perception of examination attributes, which included the quality of instructions and organization, the quality of performance, authenticity and transparency of the process, and usefulness of the OSCE as an assessment instrument compared to other formats. There was an overwhelming acceptance of OSCE in general medicine with respect to comprehensiveness (90% transparency (90% & authenticity of required tasks. Students felt that it was a useful form of examination. Student’s feedback was invaluable in influencing faculty teaching curriculum direction and appreciation of student opinion and overall the students were agreeable with newer form of OSCE. The majority of the students felt that OSCE is a fair assessment tool compared to traditional long and short cases and it covers a wide range of knowledge and clinical skills in general medicine.

    Previous studies have shown that a communications program using patient instructors (PIs) facilitates data-gathering and interpersonal skills of third-year dental students. The aim of this study was to address the question of whether those skills are retained into the students' fourth year and generalized from the classroom to the clinic. In the formative training phase, three cohorts of D3 students (N=1,038) at one dental school received instruction regarding effective patient-doctor communication; interviewed three PIs and received PI feedback; and participated in a reflective seminar with a behavioral science instructor. In the follow-up competency phase, fourth-year students performed two new patient interviews in the clinic that were observed and evaluated by clinical dental faculty members trained in communications. Mean scores on a standardized communications rating scale and data-gathering assessment were compared over training and follow-up sessions and between cohorts with a linear mixed model. The analysis showed that the third-year students' mean communication and data-gathering scores increased with each additional encounter with a PI (pcommunication scores were not only maintained but increased during the fourth-year follow-up competency evaluations (pcommunications curriculum, prior instruction facilitated the students' clinical communication performance at baseline (pCommunications program improved students' data-gathering and interpersonal skills. Those skills were maintained and generalized through completion of the D4 students' summative competency performance in a clinical setting.

    Given the university students' model role in the society and the importance of period of university education in selecting behavioral methods and lifestyles in the future have made it necessary to study the smoking pattern and its associated factors and complications among students. The aim of this study was to compare religious attitude and mental health between smoking and non-smoking students. In this research, religious attitude and mental health was studied in 1065 smoking and non-smoking students of Kerman University of Medical Sciences. In this study, three questionnaires were used (Demographic Questionnaire, General Health Questionnaire and Religious Attitude Scale Questionnaire) which were completed by the students voluntarily. The data were analyzed by descriptive statistic methods, multivariate analysis of variance (MANOVA), t-test, Pearson correlation, and regression coefficient. The mean age of smokers was 20 years and most of the smokers were male (78.9%), single (86.5%) and in BS or BA degree (52.5%). Most of them smoked a cigarette or more in the past month. The average age of start of smoking was 18 years. There was no significant difference between religious attitude and mental health in smoking students in terms of gender but in non-smoking students there was a significant difference in this regard. Smoking students had lower mental health status and religious attitude in comparison with non-smoking students. Between religious attitude and general health in smoking and non-smoking students was also a direct association. Due to psychological and physiological consequences of cigarette smoking, promoting smoking prevention by religious missionaries and university professors, and helping the students to quit smoking by counselors, psychologists and psychiatrics are necessary.

    Pathological eating attitudes and extreme weight control practices occur most commonly in certain female populations. In some young male occupation groups, such as in the armed forces, the appearance of physical strength and muscularity has particular importance. We studied body and eating attitudes and the prevalence of bodybuilding and steroid abuse in 480 military college and 752 general college male students. The Eating Disorder Inventory was used for all subjects. General college students had higher body mass index values than did military students. The prevalence of bodybuilding and steroid abuse was significantly greater in the military population. Comparisons between the study groups and within groups showed significantly different scores on certain Eating Disorder Inventory subscales. The study revealed that male military college students have some protective factors against the psychopathological features of eating disorders.

  13. Organisational aspects of dental practices: do dental students think like patients or like general dental practitioners?

    2013-02-01

    In view of transparency in health care, the widespread desire for more patient-centred care, and in an attempt to facilitate educational programmes that effectively respond to these changes, two research questions are formulated: (i) How do dental students rate the importance of various organisational aspects of dental practices compared with dental patients and general dental practitioners (GDPs), and what prescripts, defined as specific operational responsibilities of GDPs in these matters, do dental students propose? and (ii) In doing so, do students resemble patients or GDPs? In two survey studies, dental students (n = 198), patients (n = 3127) and GDPs (n = 303) were asked to rate by questionnaire the importance of 41 organisational aspects of a general dental practice and proposed specific operational responsibilities ('prescripts'). Seven of 41 aspects were rated as important by the majority of the students. Although in a different rank order, three aspects were predominantly selected by all three groups: continuing education, accessibility by telephone and Dutch-speaking GDP. For most aspects, significant differences were found between the prescripts proposed by students and those proposed by patients, and few differences were found between students and GDPs. The findings do not permit the general conclusion that the views of dental students resemble those of patients or GPDs. Looking at the overall rank order, the three respondent groups showed a great resemblance although significant differences were found for specific aspects. With regard to the proposed prescripts, students showed realistic views and the majority wants to participate in continuing education and work with protocols and guidelines. In this, they tend to resemble GDPs more than they resemble patients. © 2012 John Wiley & Sons A/S.

Results Regardless of the educational programme, female students were more positive to teamwork than male students. Nursing students in general displayed more positive beliefs about teamwork and collaboration than medical students. Exposure to different interprofessional curricula and previous exposure to interprofessional education were only to a minor extent associated with a positive attitude towards teamwork. Educational progress did not seem to influence these beliefs. Conclusions The establishment of interprofessional teamwork is a major challenge for modern healthcare. This study indicates some directions for more successful interprofessional education. Efforts should be directed at informing particularly male medical students about the need for teamwork in modern healthcare systems. The results also imply that study of other factors, such as the student's personality, is needed for fully understanding readiness for teamwork and interprofessional collaboration in healthcare. We also believe that the RIPL Scale still can be further adjusted.

    Reid, Katherine; Alberti, Hugh

    2018-04-23

    The ageing population and push to community care has significantly increased the workload of General Practitioners (GPs) in the UK and internationally. In an attempt to tackle this, NHS England has promised 5000 more GPs by 2020/21; however, recruitment is in crisis with GP training posts remaining unfilled. Little research has been carried out to assess the fundamental questions of what medical students' perceptions of General Practice are and what shapes their perceptions at medical school. We aimed to explore medical students' conceptualisations of being a GP and specifically the role of the medical school in shaping their perceptions. Two focus groups of year one and year four medical students were undertaken using an interpretive phenomenological approach. Our study has revealed that medical students perceive General Practice to lack prestige and challenge. These perceptions come, at least in part, from a process of socialisation within medical school, whereby medical students internalise and adopt their role models' perceptions and values, and the values portrayed by the hidden curriculum in their medical school culture. Perceived external pressures to pursue a career in General Practice can have a negative influence and medical schools should be made aware of this.

  17. Sleep and Mental Health in Undergraduate Students with Generally Healthy Sleep Habits.

    2016-01-01

    Whereas previous research has indicated that sleep problems tend to co-occur with increased mental health issues in university students, relatively little is known about relations between sleep quality and mental health in university students with generally healthy sleep habits. Understanding relations between sleep and mental health in individuals with generally healthy sleep habits is important because (a) student sleep habits tend to worsen over time and (b) even time-limited experience of sleep problems may have significant implications for the onset of mental health problems. In the present research, 69 university students with generally healthy sleep habits completed questionnaires about sleep quality and mental health. Although participants did not report clinically concerning mental health issues as a group, global sleep quality was associated with mental health. Regression analyses revealed that nighttime sleep duration and the frequency of nighttime sleep disruptions were differentially related to total problems and clinically-relevant symptoms of psychological distress. These results indicate that understanding relations between sleep and mental health in university students with generally healthy sleep habits is important not only due to the large number of undergraduates who experience sleep problems and mental health issues over time but also due to the potential to intervene and improve mental health outcomes before they become clinically concerning.

    Full Text Available Introduction & Objective: Depression is the most common psychiatric disorder reported among college students. Evidence suggests that depression rate is especially high among medical students. The goal of this study was to examine the relationship of general self-efficacy and social support with depression levels of university students.Materials & Methods: This was a descriptive analytic study carried out among 235 students in Hamadan University of medical sciences. Samples were classified with the appropriate assignment done and gathering information from standard questionnaires (Beck Depression Inventory test & General Self Efficacy Scale & Perceived Social Support Scale. The data were analyzed by SPSS-13.Results: 37 percent of students showed different degrees of depression. A significant negative correlation was found among depression, self efficacy (P.value= 0.000, r= -0.581, and social support (P.value= 0.000, r= -0.617. Also the results showed that there was significant relationship between depression and student's dwelling (P<0.05.Conclusion: These findings also indicated the potential roles of social support in mediating depression.

    At the present time, ambient air pollution is a serious public health problem in China. Based on the concentration-response relationship provided by international and domestic epidemiologic studies, the authors estimated the mortality and morbidity induced by the ambient air pollution of 2000. To address the mechanism of the health impact on the national economy, the authors applied a computable general equilibrium (CGE) model, named AIM/Material China, containing 39 production sectors and 32 commodities. AIM/Material analyzes changes of the gross domestic product (GDP), final demand, and production activity originating from health damages. If ambient air quality met Grade II of China's air quality standard in 2000, then the avoidable GDP loss would be 0.38%o of the national total, of which 95% was led by labor loss. Comparatively, medical expenditure had less impact on national economy, which is explained from the aspect of the final demand by commodities and the production activities by sectors. The authors conclude that the CGE model is a suitable tool for assessing health impacts from a point of view of national economy through the discussion about its applicability.

    The correct and appropriate performance of nursing skills by students can ensure patient safety and care quality. However, developing appropriate teaching and learning strategies to enhance nursing students' nursing skills and knowledge are challenging tasks for nursing faculty members. Nowadays, smartphones are popular mobile devices that are used on campuses by students and could be considered a potential tool to deliver learning materials to nursing students. This study aimed to examine the effects of a skill demonstration video delivered by smartphone on facilitating nursing students' nursing skill competency and confidence. A randomized controlled trial study design was used. A convenience sample of nursing students at a university was recruited. After receiving a regular nursing skills lab demonstration, pre-test data were collected from nursing students in an intervention group (n = 44) and a comparison group (n = 43). Then, students in the intervention group downloaded the skill demonstration video onto their smartphones, while the comparison group did not. Post-test data were collected at 2 weeks after the intervention. There were significant differences in students' urinary catheterization knowledge (F = 4.219, p = 0.04) and skills (F = 6.739, p = 0.013), but there was no difference in students' confidence level (F = 2.201, p = 0.142) between the two groups after the intervention. Furthermore, the average score of the satisfaction level regarding the intervention was 4.46 (SD = 0.43) on a scale of 1-5. This study found that delivering learning materials through smartphones to nursing students is suitable. Although there was no significant difference in students' self-confidence level, students' knowledge and skills were improved by the intervention. Smartphones can serve as a supplemental tool for learning nursing skills. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Improvements in individuals' nutrition behaviour can improve risk factors and outcomes associated with lifestyle-related chronic diseases. This study describes and compares New Zealand medical students, general practice registrars and general practitioners' (GPs') attitudes towards incorporating nutrition care into practice, and self-perceived skills in providing nutrition care. A total of 183 New Zealand medical students, 51 general practice registrars and 57 GPs completed a 60-item questionnaire investigating attitudes towards incorporating nutrition care into practice and self-perceived skills in providing nutrition care. Items were scored using a 5-point Likert scale. Factor analysis was conducted to group questionnaire items and a generalised linear model compared differences between medical students, general practice registrars and GPs. All groups indicated that incorporating nutrition care into practice is important. GPs displayed more positive attitudes than students towards incorporating nutrition in routine care (ppractice registrars were more positive than students towards performing nutrition recommendations (p=0.004), specified practices (p=0.037), and eliciting behaviour change (p=0.024). All groups displayed moderate confidence towards providing nutrition care. GPs were more confident than students in areas relating to wellness and disease (pmedical students, general practice registrars and GPs have positive attitudes and moderate confidence towards incorporating nutrition care into practice. It is possible that GPs' experience providing nutrition care contributes to greater confidence. Strategies to facilitate medical students developing confidence in providing nutrition care are warranted.

    The purpose of this study was to investigate the prevalence and the affecting factors of dysmenorrhea and its effects on overall comfort among female university students. This was a cross-sectional study. The research was carried out between October and November 2013 at a university in Ankara. This study was conducted with 200 female students. The data were analyzed using frequencies, means, SD, χ(2) tests, independent t tests and analysis of variance. Data were collected using an interview questionnaire, the visual analog scale (VAS) and the General Comfort Questionnaire. The mean age of students in this study group was 20.85 ± 2.15 years. The prevalence of dysmenorrhea in the students was 84%. The mean severity of pain was 5.78 ± 2.45 on the VAS. The present study found that 45.8% of female students experienced moderate menstrual pain and the most common co-occurring symptoms were irritability (34.6%) and fatigue (21.5%). One-fourth of the students with dysmenorrhea consulted the advice of a physician and the most commonly used methods for pain were analgesics (69%), heat application (56.5%), and rest (71.4%). Family history of dysmenorrhea, education about menstruation, and frequency of menstrual cycle were identified as important factors in the development of dysmenorrhea (p dysmenorrhea (2.57 ± 0.25) was lower than that of students without the condition (2.65 ± 0.23). Also, use of the methods for management of dysmenorrhea was found to increase students' general comfort levels. Therefore, it is important for nurses to educate and advise adolescents and young women about dysmenorrhea. Copyright © 2015 American Society for Pain Management Nursing. Published by Elsevier Inc.

    2014-01-01

    Background Many practicing physicians lack skills in physical examination. It is not known whether physical examination skills already show deficiencies after an early phase of clinical training. At the end of the internal medicine clerkship students are expected to be able to perform a general physical examination in every new patient encounter. In a previous study, the basic physical examination items that should standardly be performed were set by consensus. The aim of the current observational study was to assess whether medical students were able to correctly perform a general physical examination regarding completeness as well as technique at the end of the clerkship internal medicine. Methods One hundred students who had just finished their clerkship internal medicine were asked to perform a general physical examination on a standardized patient as they had learned during the clerkship. They were recorded on camera. Frequency of performance of each component of the physical examination was counted. Adequacy of performance was determined as either correct or incorrect or not assessable using a checklist of short descriptions of each physical examination component. A reliability analysis was performed by calculation of the intra class correlation coefficient for total scores of five physical examinations rated by three trained physicians and for their agreement on performance of all items. Results Approximately 40% of the agreed standard physical examination items were not performed by the students. Students put the most emphasis on examination of general parameters, heart, lungs and abdomen. Many components of the physical examination were not performed as was taught during precourses. Intra-class correlation was high for total scores of the physical examinations 0.91 (p internal medicine clerkship. Possible causes and suggestions for improvement are discussed. PMID:24712683

  12. Making Connections to Students' Lives and Careers Throughout a General Education Science Course

    LaDue, D. S.

    2014-12-01

    The University of Oklahoma's general education lecture course Severe & Unusual Weather, taught in two sections each fall and spring, covers about nine topics. The sections are taught by different instructors, each of whom has flexibility to employ a variety of instructional strategies and choose specific topics to cover while meeting the requirement that general education courses in the natural sciences help students understand the importance of the science for appreciating the world around them. Students enrolled have been approximately 6-10% returning adult students, some of whom were veterans or active duty military, and about 10% members of racial or ethnic groups. Their majors are mostly in the humanities (theater, photography) and social sciences (education, English, journalism, sociology), with some natural science majors (psychology, aviation). For the past two years, Section 001 has been designed with adult and active learning concepts in mind, using deliberate connections between course content and students' lives and careers to motivate meaningful learning. Students were grouped in teams according to similar majors and assigned group presentations connecting course content to topics that should interest them, such as economic impacts of weather, societal and personal impacts of severe weather, risks to aviation, media coverage of weather, and psychological and sociological responses to weather risks. Students learn about the peer review process for scientific papers while also exploring a connection of course content to their future career or life interests through papers that are run through a mock peer review process. Public policy is discussed in several sections of the course, such as hurricane building codes, wind-resistant construction in tornado alley, and the disproportionate impacts of weather and climate on certain socioeconomic groups. Most students deeply appreciate the opportunity to explore how course content intersects with their lives

  13. The effect of restructuring student writing in the general chemistry laboratory on student understanding of chemistry and on students' approach to the laboratory course

    Science.gov (United States)

    Rudd, James Andrew, II

    Many students encounter difficulties engaging with laboratory-based instruction, and reviews of research have indicated that the value of such instruction is not clearly evident. Traditional forms of writing associated with laboratory activities are commonly in a style used by professional scientists to communicate developed explanations. Students probably lack the interpretative skills of a professional, and writing in this style may not support students in learning how to develop scientific explanations. The Science Writing Heuristic (SWH) is an inquiry-based approach to laboratory instruction designed in part to promote student ability in developing such explanations. However, there is not a convincing body of evidence for the superiority of inquiry-based laboratory instruction in chemistry. In a series of studies, the performance of students using the SWH student template in place of the standard laboratory report format was compared to the performance of students using the standard format. The standard reports had Title, Purpose, Procedure, Data & Observations, Calculations & Graphs, and Discussion sections. The SWH reports had Beginning Questions & Ideas, Tests & Procedures, Observations, Claims, Evidence, and Reflection sections. The pilot study produced evidence that using the SWH improved the quality of laboratory reports, improved student performance on a laboratory exam, and improved student approach to laboratory work. A main study found that SWH students statistically exhibited a better understanding of physical equilibrium when written explanations and equations were analyzed on a lecture exam and performed descriptively better on a physical equilibrium practical exam task. In another main study, the activities covering the general equilibrium concept were restructured as an additional change, and it was found that SWH students exhibited a better understanding of chemical equilibrium as shown by statistically greater success in overcoming the common

    Blechle, Joshua M.

    unparalleled insight into the chemistry of these plasma systems. Part II of this work is focused on understanding the efficacy of a general chemistry recitation program. Such programs can be an valuable tool for improving students' problem solving skills and understanding using methods that are difficult to implement in large lecture settings. Here, general chemistry students at Colorado State University participated in a variety of recitation activities throughout the first semester of a 2-semester general chemistry sequence, including peer-led exercises, games, and scaffolded worksheets. Through weekly surveys, students were asked to evaluate and assess recitation activities for both interest and effectiveness as part of their course homework. Also included in these survey assignments were content questions relevant to the weekly themes, providing a measure of student learning of recitation topics. Student opinions were correlated with content retention, and these data were compared against student responses to a pre-survey administered before the first recitation session. This analysis allows for monitoring students' expectations of recitation courses and how well those expectations are met through the various types of activities employed. Ultimately, this work has found that students have positive feeling with respect to individual assignments, but that perspectives on chemistry and the course in general decrease dramatically from the beginning to the end of the semester. Thus, this work can serve as a significant starting points for future efforts to monitor and record student perceptions in the general chemistry recitation classroom, leading to further investigation into the source of changing attitudes and the role that week-to-week activities have on global course attitudes.

  15. Awareness, Analysis, and Action: Curricular Alignment for Student Success in General Chemistry

    Science.gov (United States)

    2018-01-01

    This article examines the ways that a shared faculty experience across five partner institutions led to a deep awareness of the curriculum and pedagogy of general chemistry coursework, and ultimately, to a collaborative action plan for student success. The team identified key differences and similarities in course content and instructional experiences. The comparative analysis yielded many more similarities than differences, and therefore, the team shifted its focus from “gap analysis” to an exploration of common curricular challenges. To address these challenges, the team developed content for targeted instructional resources that promoted the success of all STEM students across institutions. This article contextualizes the interinstitutional collaboration and closely examines the interactive components (awareness, analysis, and action), critical tools, and productive attitudes that undergirded the curricular alignment process of the STEM Transfer Student Success Initiative (t-STEM).

    Full Text Available Abstract Background Although General Practice (GP was recognized as a medical specialty in Greece in 1986, the number of GPs is insufficient to cover needs and only few medical graduates choose GP as a career option. In the present study we investigated the profile of medical students in terms of their decisions regarding specialization and the possible association of career choices different from GP with the status of undergraduate training regarding GP. Methods The sample consisted of final year students in the Medical School of the University of Athens, Greece. Students filled in a self-reported questionnaire focusing on medical specialization, and GP in particular. Results Response rate was 82.5% with 1021 questionnaires collected, out of 1237 eligible medical students. Only 44 out of the 1021 (4.3% respondents stated that GP is -or could be- among their choices for specialty. The most popular medical specialty was General Surgery (10.9%, followed by Cardiology (9.6%, Endocrinology (8.7% and Obstetrics-Gynaecology (8.3%. The most common criterion for choosing GP was the guaranteed employment on completion of the residency (54.6% while a 56.6% of total respondents were positive to the introduction of GP/FM as a curriculum course during University studies. Conclusion Despite the great needs, GP specialty is currently not a career option among undergraduate students of the greater Medical University in Greece and is still held in low esteem. A university department responsible for undergraduate teaching, promotion and research in GP (where not available is essential; the status of undergraduate training in general practice/family medicine seems to be one of the most important factors that influence physician career choices regarding primary care specialties.

  1. The effect of graphic organizers on students' attitudes and academic performance in undergraduate general biology

    Science.gov (United States)

    Cleveland, Lacy

    High attrition among undergraduate Science Technology Engineering and Mathematics (STEM) majors has led national and business leaders in the United States to call for both research and educational reform within the collegiate STEM classrooms. Included among suggestions for reform are ideas to improve retention of first-year students and to improve critical thinking and depth of knowledge, instead of covering large quantities of materials. Past research on graphic organizers suggest these tools assist students in learning information and facilitate conceptual and critical thinking. Despite their widespread use in high school science departments, collegiate humanities departments, and even medical schools, their use is considerably less prevalent in the undergraduate biology classroom. In addition to their lack of use, little research has been conducted on their academic benefits in the collegiate classroom. Based on national calls for improving retention among undergraduate STEM majors and research suggesting that academic success during an individual first major's related course highly determine if that individual will continue on in their intended major, the researcher of this dissertation chose to conduct research on an introductory general biology class. Using both quantitative and qualitative methods, the research in this dissertation examines the effectiveness of graphic organizers in promoting academic success and also examines their influence on student attitudes. This research is grounded in the theories of constructivism and cognitive load theory. Constructivism suggests that individuals must build their knowledge from their personal experiences, while the cognitive load theory recognizes the limited nature of one's working memory and suggests that instructional practices minimize cognitive overload. The results of this dissertation suggest that the use of graphic organizers in an undergraduate general biology classroom can increase students' academic

    To evaluate the knowledge of signs, symptoms and risk factors associated with oral cancer amongst undergraduate dental students and members of the general public. This study was open for a period of six months (Jan-June, 2013) to all undergraduate dental students in the 4th and 5th year of the dental science programme and dental patients attending the School of Dentistry, Griffith University, Australia. The survey evaluated the knowledge and awareness of clinical signs and symptoms and risk factors of oral cancers. A total of 100 undergraduate students and 150 patients provided informed consent and participated in this survey study. Both patients and dental students were aware of the importance of early detection of oral cancer. With the exception of smoking and persistent ulceration, this study indicated that the knowledge about oral cancer, its signs, symptoms and risk factors was limited amongst participants. This study highlights the need to raise awareness and knowledge pertaining to oral cancer, not only in the general community but also amongst those in the dental field. Specific points of concern were the common intraoral sites for oral cancer, erythroplakia as a risk factor, the synergistic action of smoking and alcohol, and HPV (human papilloma virus) as risk factors for oral cancer.

    2014-01-01

    While the Music Therapy Career Aptitude Test (MTCAT) provides a measure of student aptitude, measures of perceived self-efficacy may provide additional information about a students' suitability for a music therapy career. As a first step in determining whether future studies examining combined scores from the MTCAT and the Generalized Self-Efficacy (GSE) scale would be useful to help predict academic success in music therapy, we explored the internal reliability of these two measures in a sample of undergraduate students, and the relationship (concurrent validity) of the measures to one another. Eighty undergraduate music therapy students (14 male; 66 female) completed the MTCAT and GSE. To determine internal reliability we conducted tests of normality and calculated Cronbach's Coefficient Alpha for each measure. Pearson correlation coefficients were calculated to ascertain the strength of the relationship between the MTCAT and GSE. MTCAT scores were normally distributed and had high internal consistency (Cronbach's α = 0.706). GSE scores were not normally distributed, but had high internal consistency (Cronbach's α = 0.748). The correlation coefficient analysis revealed that MTCAT and GSE scores were moderately correlated ((r = 0.426, p music therapy students; however, a more complete picture of student suitability for music therapy may be determined by administering the GSE alongside the MTCAT. Future studies are needed to determine whether combined MTCAT and GSE scores can be used to predict student success in an undergraduate music therapy program. © the American Music Therapy Association 2014.

    Xavier University of Louisiana leads the nation in awarding BS degrees in the biological sciences to African-American students. In this multiyear study with ∼5500 participants, data-driven interventions were adopted to improve student academic performance in a freshman-level general biology course. The three hour-long exams were common and administered concurrently to all students. New exam questions were developed using Bloom’s taxonomy, and exam results were analyzed statistically with validated assessment tools. All but the comprehensive final exam were returned to students for self-evaluation and remediation. Among other approaches, course rigor was monitored by using an identical set of 60 questions on the final exam across 10 semesters. Analysis of the identical sets of 60 final exam questions revealed that overall averages increased from 72.9% (2010) to 83.5% (2015). Regression analysis demonstrated a statistically significant correlation between high-risk students and their averages on the 60 questions. Additional analysis demonstrated statistically significant improvements for at least one letter grade from midterm to final and a 20% increase in the course pass rates over time, also for the high-risk population. These results support the hypothesis that our data-driven interventions and assessment techniques are successful in improving student retention, particularly for our academically at-risk students.

    Shuang Wang

    2018-06-01

    Full Text Available Purpose: In order to train more high-level general practitioners (GPs to work in primary care institutions, China launched the 5+3 model in 2015 as a way to educate GPs nationwide. In this study, we investigated the awareness of the 5+3 model, career choices after graduation, and influences on GP career choice of undergraduate medical students from Zhengzhou University. Methods: The study population consisted of 288 undergraduate medical students from Zhengzhou University. We explored the students׳ awareness of the 5+3 model, career choices after graduation, influences on general practitioner career choice and mental status by using a self-report questionnaire and the Chinese version of the 21-item Depression Anxiety Stress Scale. Results: We found 34.2% of students did not understand the new policy. Only 23.2% of students would choose to work as a GP after graduation, and those tended to be female, to have a monthly family income less than 4000 ¥, or to be from rural areas. Only 10% of undergraduate medical students expressed a preference to work at primary care institutions. The participants showed higher anxiety and stress scores than did a previously published group of Chinese college students, and those who chose to pursue higher education had more anxiety and stress than those who decided to become general practitioners. Discussion: More efforts should be made to popularize the 5+3 model and mental intervention among medical students. More efforts should be tried to increase the income/welfare benefits and strengthen the infrastructure of primary care institutions to attract more medical students. Keywords: 5+3 model, General practitioner, Health care reform, Hierarchical medical system

    OBJECTIVE: To determine whether students acquired clinical skills as well in general practice as in hospital and whether there was any difference in the acquisition of specific skills in the two environments. DESIGN: Randomised crossover trial. SUBJECTS AND SETTING: Annual intake of first year clinical students at one medical school. INTERVENTION: A 10 week block of general internal medicine, one half taught in general practice, the other in hospital. Students started at random in one location and crossed over after five weeks. OUTCOME MEASURES: Students' performance in two equivalent nine station objective structured clinical examinations administered at the mid and end points of the block: a direct comparison of the two groups' performance at five weeks; analysis of covariance, using their first examination scores as a covariate, to determine students' relative improvement over the second five weeks of their attachment. RESULTS: 225 students rotated through the block; all took at least one examination and 208 (92%) took both. For the first half of the year there was no significant difference in the students' acquisition of clinical skills in the two environments; later, however, students taught in general practice improved slightly more than those taught in hospital (P = 0.007). CONCLUSIONS: Students can learn clinical skills as well in general practice as in hospital; more work is needed to clarify where specific skills, knowledge, and attitudes are best learnt to allow rational planning of the undergraduate curriculum.

    This work attempts to identify the level of confidence of some students of the course in Pedagogy of a public University located in the interior of the Bahia state, for the teaching of contents of Astronomy in the initial years of the Elementary School. The data was obtained from the application of a questionnaire, answered by 16 students. The analysis of these results took into account several factors, like the framework of the curriculum of the graduation course in Pedagogy, the reading profile of the students and the level of experience regarding their teaching in classroom. The obtained results point to a great insecurity of the students regarding the teaching of contents of Astronomy, being compatible with previous findings of other investigators of the area.

    The first objective of this study was to ascertain the prevalence of general joint hypermobility (GJH) and joint hypermobility syndrome (JHS) in BA Dance Theatre 1st and 3rd year students at a contemporary dance conservatory. The second objective was to determine the statistical correlation between GJH, JHS, and injury in this population. A total of 85 (female, N = 78; male, N = 7) contemporary dance students participated in the study. The Beighton score (with a forward flexion test modification) was used to determine GJH, and the Brighton criteria were used to verify JHS. Participants completed a self-reported injury questionnaire that included type of injury (physical complaint, medical diagnosis, or time-loss) and injury frequency. Statistical analysis (Pearson correlation) was used to correlate GJH, JHS, and frequency-of-injury scores. Overall, 69% of the students were found to have GJH, and 33% had JHS. A statistical correlation of r = + 0.331 (p dance students and suggests that screening programs should include the Brighton criteria to identify JHS in these dancers. Subsequent injury tracking and injury prevention programs would then provide data for further research in this area.

    This thesis describes an action research investigation of improvements to instruction in General Chemistry at Purdue University. Specifically, the study was conducted to guide continuous reform of curriculum materials delivered via the World Wide Web by involving students, instructors, and curriculum designers. The theoretical framework for this study was based upon constructivist learning theory and knowledge claims were developed using an inductive analysis procedure. This results of this study are assertions made in three domains: learning chemistry content via the World Wide Web, learning about learning via the World Wide Web, and learning about participation in an action research project. In the chemistry content domain, students were able to learn chemical concepts that utilized 3-dimensional visualizations, but not textual and graphical information delivered via the Web. In the learning via the Web domain, the use of feedback, the placement of supplementary aids, navigation, and the perception of conceptual novelty were all important to students' use of the Web. In the participation in action research domain, students learned about the complexity of curriculum. development, and valued their empowerment as part of the process.

    Objectives Expanding learner cohorts of medical students and general practitioner (GP) vocational trainees and the impending retirement of the 'baby boomer' GP cohort threaten the teaching and supervisory capacity of the Australian GP workforce. Engaging newly qualified GPs is essential to sustaining this workforce training capacity. The aim of the present study was to establish the prevalence and associations of in-practice clinical teaching and supervision in early career GPs. Methods The present study was a cross-sectional questionnaire-based study of recent (within 5 years) alumni of three of Australia's 17 regional general practice training programs. The outcome factor was whether the alumnus taught or supervised medical students, GP registrars or other learners in their current practice. Logistic regression analysis was used to establish associations of teaching and supervision with independent variables comprising alumnus demographics, current practice characteristics and vocational training experiences. Results In all, 230 alumni returned questionnaires (response rate 37.4%). Of currently practising alumni, 52.4% (95% confidence interval (CI) 45.6-59.0%) reported current teaching or supervisory activities. Factors significantly (Pinterest in and undertaking of teaching roles have been documented for GP or family medicine trainees, studies investigating the engagement in these clinical roles by GPs during their early post-training period are lacking. What does this paper add? This paper is the first to document the prevalence of teaching and supervision undertaken by early career GPs as part of their regular clinical practice. We also demonstrate associations of practice rurality, country of medical graduation and undertaking non-practice-based clinical roles with GPs' engagement in teaching and supervisory roles. What are the implications for practitioners? Establishing current teaching patterns of GPs enables appropriate targeting of new strategies to

    To compare medical students' skills for vaginal operative delivery by vacuum extraction (VE) after hands-on training versus video demonstration. We randomized medical students to an expert demonstration (group 1) or a hands-on (group 2) training using a standardized VE algorithm on a pelvic training model. Students were tested with a 40-item Objective Structured Assessment of Technical Skills (OSATS) scoring system after training and 4 days later. OSATS scores were the primary outcome. Performance time, self-assessment, confidence, and global rating scale were secondary outcomes. We assessed the constructive validity of OSATS in this VE model comparing metric scores of experts and students. In all, 137 students were randomized. OSATS scores were higher in group 2 (n = 63) compared with group 1 (n = 74) (32.89 ± 6.39 vs 27.51 ± 10.27, respectively; P training is superior to video demonstration for teaching VE on a pelvic model.

    Quality of life is an essential component of learning and has strong links with the practice and study of medicine. There is burgeoning evidence in the research literature to suggest that medical students are experiencing health-related problems such as anxiety, depression, and burnout. The aim of the study was to investigate medical students' perceptions concerning their quality of life. Two hundred seventy-four medical students studying in their early clinical years (response rate = 80%) participated in the present study. Medical students were asked to fill in the abbreviated version of the World Health Organization Quality of Life questionnaire to elicit information about their quality of life perceptions in relation to their physical health, psychological health, social relationships, and environment. Subsequently, their responses were compared with two nonmedical students groups studying at a different university in the same city and an Australian general population norm. The findings were compared using independent group's t tests, confidence intervals, and Cohen's d. The main finding of the study indicated that medical students had similar quality of life perceptions to nonmedical students except in relation to the environment domain. Furthermore, the medical student group scored lower than the general population reference group on the physical health, psychological health, and environment quality of life domains. The results suggest that all university students are expressing concerns related to quality of life, and thus their health might be at risk. The findings in this study provided no evidence to support the notion that medical students experience lower levels of quality of life compared to other university students. When compared to the general population, all student groups examined in this study appeared to be experiencing lower levels of quality of life. This has implications for pastoral support, educationalists, student support personnel, and the

    Background In Japan, there is a shortage of young physicians in various specialties; the present situation of general medicine or family medicine (GM/FM) in particular is risky. The factors influencing the career choice of Japanese medical students are poorly understood. This study aims to identify factors related to choosing GM/FM as a career. Methods The study was designed as a cross-sectional survey. Students at one medical school in Japan filled out a questionnaire. Students were asked to state their intended medical specialty, and they rated the importance of specific individual and occupational aspects using a 4-point likert scale. Factor analysis was performed on the variables. Reliability of the factor scores was estimated using Cronbach‘s alpha coefficients; biserial correlations between the factors and career choices were calculated. Furthermore, multiple linear regression analysis was performed using career choice (GM/FM vs. others) as the criterion variable and the factors plus demographic characteristics as confounding variables. Results Factor analysis produced six factors that explained future career plans. Medical students in this study had a positive and realistic idea about GM/FM, but only 18.8% of them chose GM/FM first as a career. The significant variables associated with choosing GM/FM first as a career were: ‘Admission from hometown’ (β=0.189, P=0.001), ‘Student preparing for the entrance exam’ (β=0.172; P=0.001), ‘Intent for rural practice’ (β=0.123, P=0.016), and ‘Work–life balance’ (β=0.126, P=0.013). While significant variables that were negatively associated with choosing GM/FM were ‘Presence of medical relatives’ (β=−0.107, P=0.037) and ‘Scientific orientation’ (β=−0.125, P=0.013). Conclusions Strategies have been suggested, such as recruiting medical students with significant variables that were associated with choosing GM/FM first as a career.

    Medical students and residents often make specialty and practice choices with limited exposure to aspects of professional and personal life in general surgery. The purpose of this study was to portray practice composition, career choices, professional experiences, job satisfaction, and personal life characteristics specific to practicing general surgeons in the United States. A 131-question survey was mailed to all female members (n = 1,076) and a random 2:1 sample of male members (n = 2,152) of the American College of Surgeons in three mailings between September 1998 and March 1999. Respondents who were not actively practicing general surgery in the United States and both trainees and surgeons who did not fit the definition of private or academic practice were excluded. Detailed questions regarding practice attributes, surgical training, professional choices, harassment, malpractice, career satisfaction, and personal life characteristics were included. Separate five-point Likert scales were designed to measure influences on career choices and satisfaction with professional and personal matters. Univariate analyses were used to analyze responses by surgeon age, gender, and practice type. A response rate of 57% resulted in 1,532 eligible responses. Significant differences between private and academic practice were noted in case composition, practice structure, and income potential; no major differences were seen in malpractice experience. Propensity for marriage and parenthood differed significantly between men and women surgeons. Overall career satisfaction was very high regardless of practice type. Some differences by surgeon gender in perceptions of equal career advancement opportunities and of professional isolation were noted. This study offers a comprehensive view of general surgery to enable more informed decisions among medical students and residents regarding specialty choice or practice opportunities.

    Azevedo, Caio L. N.; Migon, Helio S.

    2012-10-01

    In this paper we introduce a new item response theory (IRT) model with a generalized Student t-link function with unknown degrees of freedom (df), named generalized t-link (GtL) IRT model. In this model we consider only the difficulty parameter in the item response function. GtL is an alternative to the two parameter logit and probit models, since the degrees of freedom (df) play a similar role to the discrimination parameter. However, the behavior of the curves of the GtL is different from those of the two parameter models and the usual Student t link, since in GtL the curve obtained from different df's can cross the probit curves in more than one latent trait level. The GtL model has similar proprieties to the generalized linear mixed models, such as the existence of sufficient statistics and easy parameter interpretation. Also, many techniques of parameter estimation, model fit assessment and residual analysis developed for that models can be used for the GtL model. We develop fully Bayesian estimation and model fit assessment tools through a Metropolis-Hastings step within Gibbs sampling algorithm. We consider a prior sensitivity choice concerning the degrees of freedom. The simulation study indicates that the algorithm recovers all parameters properly. In addition, some Bayesian model fit assessment tools are considered. Finally, a real data set is analyzed using our approach and other usual models. The results indicate that our model fits the data better than the two parameter models.

    Preclinical fixed prosthodontics is taught by Department of Prosthodontics faculty members at Virginia Commonwealth University School of Dentistry; however, 86% of all clinical cases in academic year 2012 were staffed by faculty members from the Department of General Practice. The aims of this retrospective study were to quantify the quality of impressions, accuracy of laboratory work authorizations, and most common errors and to determine if there were differences between the rate of errors in cases supervised by the prosthodontists and the general dentists. A total of 346 Fixed Prosthodontic Laboratory Tracking Sheets for the 2012 academic year were reviewed. The results showed that, overall, 73% of submitted impressions were acceptable at initial evaluation, 16% had to be poured first and re-evaluated for quality prior to pindexing, 7% had multiple impressions submitted for transfer dies, and 4% were rejected for poor quality. There were higher acceptance rates for impressions and work authorizations for cases staffed by prosthodontists than by general dentists, but the differences were not statistically significant (p=0.0584 and p=0.0666, respectively). Regarding the work authorizations, 43% overall did not provide sufficient information or had technical errors that delayed prosthesis fabrication. The most common errors were incorrect mountings, absence of solid casts, inadequate description of margins for porcelain fused to metal crowns, inaccurate die trimming, and margin marking. The percentages of errors in cases supervised by general dentists and prosthodontists were similar for 17 of the 18 types of errors identified; only for margin description was the percentage of errors statistically significantly higher for general dentist-supervised than prosthodontist-supervised cases. These results highlighted the ongoing need for faculty development and calibration to ensure students receive the highest quality education from all faculty members teaching fixed

    Alcohol marketers have increasingly moved their advertising efforts into digital and social media venues. As a result, the purpose of this study is to investigate associations between students' use of social media, their exposure to alcohol marketing messages through social media, and their alcohol-related beliefs and behaviors. Public and private university students (N = 637) participated November and December 2011 and April 2012. College students completed online surveys to measure their exposure to social and online media generally, as well as their alcohol-related digital media use and alcohol use. Use of social media related to alcohol marketing predicted alcohol consumption and engaging in risky behaviors, whereas the use of social media more generally did not. Students' use of alcohol-related social media-marketing content associates with their problem drinking. Results have implications for alcohol abuse reduction efforts targeted at college students and suggest the importance of considering social, cultural, and cognitive factors in campaign planning and design.

    2015-01-01

    To assess self-reported stress during the performance of different procedures in pediatric dentistry, according to the professional experience of the dentists. During the years 2010 to 2011, an anonymous survey was administered by means of an internet link, and by distribution at professional meetings of dentists . No statistically significant differences in stress were reported for maxilla and mandibular procedures. Placement of a rubber dam was rated as the most stressful procedure among dental students. For general practitioners and specialists, injection of local anesthesia to an anxious child was the most stressful procedure, regardless of age, sex, or years of professional experience. A negative correlation was found between years of experience and level of stress for all the procedures surveyed, but not for the use of nitrous oxide. No differences were found between male and female dentists in stress scores for any of the procedures. Higher rates of stress during operative procedures were reported among dental students than among experienced dentists. Anxiety of the pediatric patients, but not the location of the procedure: maxillary or mandibular, affected the dentists' reported level of stress.

    Our aims were to assess the perceptions of orthodontic case complexity among orthodontists, general dentists, orthodontic residents, and dental students and to compare their perceptions with the American Board of Orthodontics Discrepancy Index (DI). Orthodontists, general dentists, orthodontic residents, and dental students (n = 343) participated in a Web-based survey. Pretreatment orthodontic records of 29 cases with varying DI scores were obtained. Respondents were asked to evaluate case complexity on a 100-point visual analog scale. Additional information was collected on participants' orthodontic education and orthodontic treatment preferences. Pearson correlation coefficients were used to assess the relationship between the average complexity score and the DI score. Repeated measures analysis with linear mixed models was used to assess the association between the average complexity score and the DI score and whether the association between the 2 scores varied by level of difficulty or panel group. The level of significance for all analyses was set at P clear aligners. DI score was significantly associated with complexity perceptions (P = 0.0168). Associations between average complexity and DI score varied significantly by provider group (P = 0.0033), with orthodontists and residents showing the strongest associations. When the DI score was greater than 15, orthodontists and residents perceived cases as more complex than did the other provider groups. Orthodontists and orthodontic residents had better judgments for evaluating orthodontic case complexity. The high correlation between orthodontic professionals' perceptions and DI scores suggested that additional orthodontic education and training have an influence on the ability to recognize case complexity.

    The purpose of our study was to determine the predictive impact of individual academic measures for the matriculation of senior medical students into a general surgery residency. Academic records were evaluated for third-year medical students (n = 781) at a single institution between 2004 and 2011. Cohorts were defined by student matriculation into either a general surgery residency program (n = 58) or a non-general surgery residency program (n = 723). Multivariate logistic regression was performed to evaluate independently significant academic measures. Clinical evaluation raw scores were predictive of general surgery matriculation (P = .014). In addition, multivariate modeling showed lower United States Medical Licensing Examination Step 1 scores to be independently associated with matriculation into general surgery (P = .007). Superior clinical aptitude is independently associated with general surgical matriculation. This is in contrast to the negative correlation United States Medical Licensing Examination Step 1 scores have on general surgery matriculation. Recognizing this, surgical clerkship directors can offer opportunities for continued surgical education to students showing high clinical aptitude, increasing their likelihood of surgical matriculation.

    Full Text Available Background and Objectives: Abdominal and general obesities are greatly affected by diet and physical activities. Prevalence of this complication in communities has an increasing trend, so that even adolescents are no exception in this regard. The current study aimed to investigate abdominal and general obesity and its related factors in’ students of Qom city. Methods: This cross-sectional study was conducted on 301 (17 girls and 114 boys students in medical and Azad universities in Qom city. These individuals were selected by proportional to size sampling method and studied by anthropometric measures, international short physical activity questionnaire, and 11-item nutritional habits questionnaire. Data were analyzed by independent t-, chi-square, and correlation coefficient tests. The significance level was considered to be α=0.05. Results: The mean BMI and WHR in students was 22.6±3.2kg/m2 and 0.8±0.0, respectively. A significant direct correlation was observed between anthropometric measures and abdominal obesity. Only 23.3% of the students had regular sport activity, so that the mean light physical activity in obese students was lower than normal students (38.9±43.1 vs. 60.8±67.5min. No heavy physical activity was seen in this group, and fast-food consumption was higher in this group of students compared to the normal students (93.2% vs. 67.8%. Conclusion: According to the findings of this study, there is a significant relationship between nutritional status and level of physical activity and abdominal and general obesity. Therefore, overweight, abdominal, and general obesity were lower in male students, and subjects involved in regular physical activity and lower fast-food consumption.

    Germany is witnessing an increasing shortage of general practitioners (GPs). The aim was to determine predictors of the job-related motivation of medical students of three medical faculties with different institutionalisation of general practice as an academic discipline. Medical students were surveyed with a standardised questionnaire about their attitudes towards general practice and their motivation to work as a GP in different working conditions. Predictors for positive attitudes and motivation were calculated using logistic regression models. 940 (15.2%) out of 6182 medical students from three Bavarian medical faculties participated in an online survey. 585 (62.7%) were female, and the average age was 25.0 (standard deviation 3.7). The average grade of a university-entrance diploma was 1.6 (standard deviation 0.5). 718 (76.4%) could imagine working as a GP. However, they favoured being employed within another organisation and not having their own private practice (65.5% vs. 35.1%). "Presence of a professorship of general practice" was associated with a positive attitude towards general practice (OR 1.57; 95%CI 1.13-2.417). Motivation for working as a GP was associated with "being female" (OR 2.56; 95%CI 1.80-3.56) and "presence of a professorship of general practice" (OR 1.68; 95%CI 1.14-2.46). Having a lower grade for one's university-entrance diploma was associated with a higher preference to work in one's own practice (OR 1.39; 95%CI 1.02-1.90). A high amount of medical students were open-minded towards general practice. However, they favoured employment within an organization over working in their own practice. Institutionalisation of general practice as an academic discipline might be of importance to gain positive attitudes towards general practice and motivate medical students to work as a GP.

    Construct: Clinical skills are used in the care of patients, including reporting, diagnostic reasoning, and decision-making skills. Written comprehensive new patient admission notes (H&Ps) are a ubiquitous part of student education but are underutilized in the assessment of clinical skills. The interpretive summary, differential diagnosis, explanation of reasoning, and alternatives (IDEA) assessment tool was developed to assess students' clinical skills using written comprehensive new patient admission notes. The validity evidence for assessment of clinical skills using clinical documentation following authentic patient encounters has not been well documented. Diagnostic justification tools and postencounter notes are described in the literature (1,2) but are based on standardized patient encounters. To our knowledge, the IDEA assessment tool is the first published tool that uses medical students' H&Ps to rate students' clinical skills. The IDEA assessment tool is a 15-item instrument that asks evaluators to rate students' reporting, diagnostic reasoning, and decision-making skills based on medical students' new patient admission notes. This study presents validity evidence in support of the IDEA assessment tool using Messick's unified framework, including content (theoretical framework), response process (interrater reliability), internal structure (factor analysis and internal-consistency reliability), and relationship to other variables. Validity evidence is based on results from four studies conducted between 2010 and 2013. First, the factor analysis (2010, n = 216) yielded a three-factor solution, measuring patient story, IDEA, and completeness, with reliabilities of .79, .88, and .79, respectively. Second, an initial interrater reliability study (2010) involving two raters demonstrated fair to moderate consensus (κ = .21-.56, ρ =.42-.79). Third, a second interrater reliability study (2011) with 22 trained raters also demonstrated fair to moderate agreement

    Full Text Available Introduction : various methods of teaching have different learning outcomes. Using a combination of teaching and training methods of training may boost education. This study compared lecture based and case based teaching as a combined approach in learning general surgery by medical students. Methods: This study was a quasi-experimental performed on two consecutive groups of 33 and 36 students who were studying general surgery course. The two styles of teaching were lecture-based and real case teaching methods. The final exam included twenty multiple choice questions. The mean scores of each group of students were collected and analyzed accordingly with descriptive tests, Fisher’s test and T-test. Results: The mean final mark of students' who received real case based education was 16.8/20 ± 1.8 and for the lecture group was 12.7± 1.7. There was a significant difference between the two groups (P <0.0001. In both groups, there were significant differences in the mean scores of questions with taxonomy two and three, but not in the questions with taxonomy one. Students' evaluation score of the teacher of the real case group increased by 1.7/20 (8.7% in the case based group compared to the lecture group. Conclusions: Case based teaching of general surgery led to a better outcome and students were more satisfied. It is recommended that case based education of surgery be encouraged.

    Internalizing problems are common among college students and have been linked consistently to deficits in emotion regulation (ER). Also, hostility/anger (animosity toward others, phenomenological aspect of anger) is an important feature of internalizing problems, but has received limited attention as a mediator between ER and outcomes. Results (N = 160) indicated that although college students' ER abilities corresponded with all three types of internalizing symptoms, hostility/anger mediated fully the relationship for symptoms of depression and social anxiety, but not generalized anxiety (GAD). The stronger interpersonal aspect inherent in depression and social anxiety relative to GAD may in part explain findings, but findings must be viewed in lieu of limitations, which include self-report, a non-clinical sample, and a cross-sectional design. Overall, hostility/anger may be important to address in interventions and programs aimed at reducing internalizing problems, especially among those who demonstrate ER deficits and are prone to depression and social anxiety.

  8. Picture this: The value of multiple visual representations for student learning of quantum concepts in general chemistry

    Science.gov (United States)

    Allen, Emily Christine

    Mental models for scientific learning are often defined as, "cognitive tools situated between experiments and theories" (Duschl & Grandy, 2012). In learning, these cognitive tools are used to not only take in new information, but to help problem solve in new contexts. Nancy Nersessian (2008) describes a mental model as being "[loosely] characterized as a representation of a system with interactive parts with representations of those interactions. Models can be qualitative, quantitative, and/or simulative (mental, physical, computational)" (p. 63). If conceptual parts used by the students in science education are inaccurate, then the resulting model will not be useful. Students in college general chemistry courses are presented with multiple abstract topics and often struggle to fit these parts into complete models. This is especially true for topics that are founded on quantum concepts, such as atomic structure and molecular bonding taught in college general chemistry. The objectives of this study were focused on how students use visual tools introduced during instruction to reason with atomic and molecular structure, what misconceptions may be associated with these visual tools, and how visual modeling skills may be taught to support students' use of visual tools for reasoning. The research questions for this study follow from Gilbert's (2008) theory that experts use multiple representations when reasoning and modeling a system, and Kozma and Russell's (2005) theory of representational competence levels. This study finds that as students developed greater command of their understanding of abstract quantum concepts, they spontaneously provided additional representations to describe their more sophisticated models of atomic and molecular structure during interviews. This suggests that when visual modeling with multiple representations is taught, along with the limitations of the representations, it can assist students in the development of models for reasoning about

  9. Students' Learning of a Generalized Theory of Sound Transmission from a Teaching-Learning Sequence about Sound, Hearing and Health

    Science.gov (United States)

    West, Eva; Wallin, Anita

    2013-04-01

    Learning abstract concepts such as sound often involves an ontological shift because to conceptualize sound transmission as a process of motion demands abandoning sound transmission as a transfer of matter. Thus, for students to be able to grasp and use a generalized model of sound transmission poses great challenges for them. This study involved 199 students aged 10-14. Their views about sound transmission were investigated before and after teaching by comparing their written answers about sound transfer in different media. The teaching was built on a research-based teaching-learning sequence (TLS), which was developed within a framework of design research. The analysis involved interpreting students' underlying theories of sound transmission, including the different conceptual categories that were found in their answers. The results indicated a shift in students' understandings from the use of a theory of matter before the intervention to embracing a theory of process afterwards. The described pattern was found in all groups of students irrespective of age. Thus, teaching about sound and sound transmission is fruitful already at the ages of 10-11. However, the older the students, the more advanced is their understanding of the process of motion. In conclusion, the use of a TLS about sound, hearing and auditory health promotes students' conceptualization of sound transmission as a process in all grades. The results also imply some crucial points in teaching and learning about the scientific content of sound.

  10. The Impact of Different Instructional Strategies on Students' Understanding about the Cell Cycle in a General Education Biology Course

    Krishnamurthy, Sanjana

    This study investigated the impact of different instructional strategies on students' understanding about the cell cycle in a general education biology course. Although several studies have documented gains in students' cell cycle understanding after instruction, these studies generally use only one instructional method, often without a comparison group. The goal of this study was to learn more about students' misconceptions about the cell cycle and how those ideas change after three different evidence-based learning experiences in undergraduate general education. Undergraduate students in six laboratory sections (n = 24; N = 144) in a large public institution in the western United States were surveyed pre- and post-instruction using a 14-item valid and reliable survey of cell cycle knowledge. Cronbach's alpha for the standard scoring convention was 0.264 and for the alternate scoring convention was 0.360, documenting serious problems with inconsistent validity and reliability of the survey. Operating as though the findings are at least a proxy for actual cell cycle knowledge, score comparisons by groups of interest were explored, including pre- and post-instruction differences among demographic groups of interest and three instructional settings: a bead modeling activity, a role-playing game, and 5E instructional strategy. No significant differences were found across groups of interest or by strategy, but some significant item-level differences were found. Implications and discussion of these shifts is noted in lieu of the literature.

    2012-08-01

    Full Text Available Abstract Background Research literature consistently documents that scientifically based therapeutic recommendations are not always followed in the hospital or in the primary care setting. Currently, there is evidence that some general practitioners in Australia are not prescribing appropriately for patients diagnosed with 1 hypertension (HT and 2 chronic heart failure (CHF. The objectives of this study were to improve general practitioner’s drug treatment management of these patients through feedback on their own prescribing and small group discussions with peers and a trained group facilitator. The impact evaluation includes quantitative assessment of prescribing changes at 6, 9, 12 and 18 months after the intervention. Methods A pragmatic multi site cluster RCT began recruiting practices in October 2009 to evaluate the effects of a multi-faceted quality improvement (QI intervention on prescribing practice among Australian general practitioners (GP in relation to patients with CHF and HT. General practices were recruited nationally through General Practice Networks across Australia. Participating practices were randomly allocated to one of three groups: two groups received the QI intervention (the prescribing indicator feedback reports and small group discussion with each group undertaking the clinical topics (CHF and HT in reverse order to the other. The third group was waitlisted to receive the intervention 6 months later and acted as a “control” for the other two groups. De-identified data on practice, doctor and patient characteristics and their treatment for CHF and HT are extracted at six-monthly intervals before and after the intervention. Post-test comparisons will be conducted between the intervention and control arms using intention to treat analysis and models that account for clustering of practices in a Network and clustering of patients within practices and GPs.

  3. The role of self-regulated learning in explaining examination performance of college students in first-semester general chemistry

    Science.gov (United States)

    Beckley, Scott

    Many college students struggle with first-semester general chemistry. Prior studies have shown that a student's prior knowledge of chemistry, a cognitive factor, does not account for the total variance when measured by examination scores. This study explored the role of self-regulated learning (SRL) to identify the degree of success or failure of students with two outcome variables (i.e., American Chemical Society Comprehensive First-Term General Chemistry Examination (Form 2009) and hour-examination averages). The SRL construct consists of three interrelated components (i.e., cognitive, metacognitive, and motivational). SRL theory focuses on the idea of reciprocal determinism, in which the impact of one component of self-regulation affects the other two components. In the quantitative portion of this mixed methods study, eight measures of SRL were used to determine the `level' of self-regulation for each student. SRL variables were used in regression analysis and provided additional and unique variances. Cluster analysis techniques identified two distinct groups of students (i.e., adaptive and maladaptive). Generally, adaptive learners were associated with higher levels of SRL and success in the course; maladaptive learners had lower levels of SRL and struggled with the course demands. For the qualitative portion of the study, student volunteers (n = 8) were interviewed to gauge their views on the role of instruction in influencing their examination performances. The findings indicated that perceptions of teaching methods, demands of the course, course structure, feedback, and assessments were associated with the students' levels of self-regulation. Interviews revealed four SRL styles. Rote memorizers tended to fragment instruction and then memorize each fragment, while algorithmic memorizers tended to imitate the step-by-step problem-solving strategies of the instructor or the textbook. Globalizers were intrinsically motivated to learn the material but tended to

    Heming, Thomas A; Nandagopal, Shobha

    2012-11-01

    Medical education requires student comprehension of both technical (scientific/medical) and non-technical (general) vocabulary. Our experience with "English as a second language" (ESL) Arab students suggested they often have problems comprehending scientific statements because of weaknesses in their understanding of non-scientific vocabulary. This study aimed to determine whether ESL students have difficulties with general vocabulary that could hinder their understanding of scientific/medical texts. A survey containing English text was given to ESL students in the premedical years of an English-medium medical school in an Arabic country. The survey consisted of sample questions from the Medical College Admission Test (USA). Students were instructed to identify all unknown words in the text. ESL students commenced premedical studies with substantial deficiencies in English vocabulary. Students from English-medium secondary schools had a selective deficiency in scientific/medical terminology which disappeared with time. Students from Arabic-medium secondary schools had equal difficulty with general and scientific/medical vocabulary. Deficiencies in both areas diminished with time but remained even after three years of English-medium higher education. Typically, when teaching technical subjects to ESL students, attention is focused on subject-unique vocabulary and associated modifiers. This study highlights that ESL students also face difficulties with the general vocabulary used to construct statements employing technical words. Such students would benefit from increases in general vocabulary knowledge.

    2017-01-01

    Background: Primary health care in rural regions is currently undergoing a global crisis in respect of the next generation of practitioners. National and international recommendations advise placing greater emphasis upon practical skills and competences in medical studies. It is also in the interest of training the next generation to include mentoring and longitudinal integration of contact to teaching practices for general medicine in an early stage. Consequently, the General Practice Class (KAM) was introduced in Halle in 2011 as an elective with 20 individually mentored students per year, beginning with the first subject-related semester. We are now reporting on the results of the evaluation for the first two years. Method: A standardised online survey was carried out with all students who took part in the KAM in the two years 2011 and 2012 (N=38). For both years the survey was made at the end of the first summer semester on the basis of an adapted version of the Heidelberger Inventar zur Lehrevaluation (Heidelberg Inventory for the Evaluation of Teaching, HILVE-II) and the Berliner Evaluationsinstrument für selbsteingeschätzte, studentische Kompetenzen (Berlin Evaluation Instrument for the self-assessment of student competences, BEvaKomp) . Furthermore, each year the preference for the choice of specialty and location of a medical practice was queried. Predictors for the preference of the chosen specialty and the location of a medical practice were estimated by binary logistic regression analysis. Via univariate evaluations the number of students who reported an increase in knowledge in different areas of competence as a result of the KAM was counted. Correlations between the intention to remain in the KAM and the quality of teaching were evaluated on the basis of bivariate correlations. Results: 48% of the students agreed partly or fully that the KAM seminars enhanced their specialist competence. This individual acquiring of competence in the model project

    Full Text Available Background and purpose: Multiple choice tests are the most common type of tests used in evaluating the general English knowledge of the students in most medical universities, however the efficacy of these tests are not examined precisely. Wecompare and examine the integrative tests and discrete point tests as measures of the English language knowledge of medical students.Methods: Three tests were given to 60 undergraduate physiotherapy and Audiology students in their second year of study (after passing their general English course. They were divided into 2 groups.The first test for both groups was an integrative test, writing. The second test was a multiple - choice test 0.(prepositions for group one and a multiple - choice test of tensesfor group two. The same items which were mostfi-equently used wrongly in thefirst test were used in the items of the second test. A third test, a TOEFL, was given to the subjects in order to estimate the correlation between this test and tests one and two.Results: The students performed better in the second test, discrete point test rather than the first which was an integrative test. The same grammatical mistakes in the composition were used correctly in the multiple choice tests by the students.Conclusion:Our findings show that student perform better in non-productive rather than productive test. Since being competent English language user is an expected outcome of university language courses it seems warranted to switch to integrative tests as a measure of English language competency.Keywords: INTEGRATIVE TESTS, ENGLISH LANGUAGE FOR MEDICINE, ACADEMIC ENGLISH

Therefore, this study investigated the relationship between the excessive use of mobile phones and general health and quality of sleep on 450 Occupational Health and Safety (OH&S) students in five universities of medical sciences in the North East of Iran in 2014. To achieve this objective, special questionnaires that included Cell Phone Overuse Scale, Pittsburgh's Sleep Quality Index (PSQI) and General Health Questionnaire (GHQ) were used, respectively. In addition to descriptive statistical methods, independent t-test, Pearson correlation, analysis of variance (ANOVA) and multiple regression tests were performed. The results revealed that half of the students had a poor level of sleep quality and most of them were considered unhealthy. The Pearson correlation co-efficient indicated a significant association between the excessive use of mobile phones and the total score of general health and the quality of sleep. In addition, the results of the multiple regression showed that the excessive use of mobile phones has a significant relationship between each of the four subscales of general health and the quality of sleep. Furthermore, the results of the multivariate regression indicated that the quality of sleep has a simultaneous effect on each of the four scales of the general health. Overall, a simultaneous study of the effects of the mobile phones on the quality of sleep and the general health could be considered as a trigger to employ some intervention programs to improve their general health status, quality of sleep and consequently educational performance.

    This article assesses the perceived value of a simulated general dental practice centre as reported by past undergraduates over five years. Various aspects of teaching and related outcomes are explored based on responses received from anonymous questionnaires. A team based approach to cooperative learning led by current practitioners experienced in primary dental care was seen as pivotal to the huge success of the teaching model. Moreover the role of cooperative learning and its influence on building individual clinical confidence and acumen was considered highly beneficial as part of the transition from novice to expert. An anonymous questionnaire was distributed to students six months after qualification for a period of five years. The last registered postal address held by the Institute was used for this purpose. The years surveyed were: 2001-2002, 2002-2003, 2003-2004, 2005-2006 and 2007-2008. The questionnaire provided for both qualitative aspects of feedback and a quantitative representation of the overall perception of effectiveness of the General Dental Practice Centre, as expressed by a visual analogue scale. In total 135 questionnaires were returned representing a return rate of 53%. From the responses received 99% of the students reported that they enjoyed their sessions at the Centre with 96% expressing satisfaction with the teaching regime. The mean visual analogue scale rating the centre overall was reported as 83%, with a year on year increase ranging from 76-92%. Rich qualitative data were derived from free text responses. A simulated general dental practice centre was highly rated by past dental students in terms of the overall learning experience received and its relevance to later vocational training. By far the most consistently reported attribute was the opportunity to practise close support four handed dentistry with a nurse. Training in practice management and organisational skills were viewed as important with effective teamwork and a

    Purpose: Demonstrate and quantify the augmented resolution due to focalspot size decrease in images acquired on the anode side of the field, for both small and medium (0.3 and 0.6mm) focal-spot sizes using the experimental task-based GM-ROD metric. Theoretical calculations have shown that a medium focal-spot can achieve the resolution of a small focal-spot if acquired with a tilted anode, effectively providing a higher-output small focal-spot. Methods: The MAF-CMOS (micro-angiographic fluoroscopic complementary-metal-oxide semiconductor) detector (75µm pixel pitch) imaged two copper wire segments of different diameter and a pipeline stent at the central axis and on the anode side of the beam, achieved by tilting the x-ray C-arm (Toshiba Infinix) to 6° and realigning the detector with the perpendicular ray to correct for x-ray obliquity. The relative gain in resolution was determined using the GM-ROD metric, which compares images on the basis of the Fourier transform of the image and the measured NNPS. To emphasize the geometric unsharpness, images were acquired at a magnification of two. Results: Images acquired on the anode side were compared to those acquired on the central axis with the same target-area focal-spot to consider the effect of an angled tube, and for all three objects the advantage of the smaller effective focal-spot was clear, showing a maximum improvement of 36% in GM-ROD. The images obtained with the small focal-spot at the central axis were compared to those of the medium focal-spot at the anode side and, for all objects, the relative performance was comparable. Conclusion: For three objects, the GM-ROD demonstrated the advantage of the anode side focal-spot. The comparable performance of the medium focal-spot on the anode side will allow for a high-output small focal-spot; a necessity in endovascular image-guided interventions.

    Smartphones and related applications are increasingly gaining relevance in the healthcare domain. We previously assessed the demands and preferences of medical students towards an application accompanying them during a course on general practice. The current study aims to elucidate the factors associated with adoption of such a technology. Therefore we provided students with a prototype of an application specifically related to their studies in general practice. A total estimation among students participating in a general practice examination at the Leipzig Medical School was conducted in May 2014. Students were asked to answer a structured self-designed questionnaire. Univariable comparisons were made to identify significant differences between those students who reported to have used the application frequently and those who did not. Multivariable binary logistic regression was used to reveal independent predictors of frequent application usage. The response rate was 99.3 % (n = 305/307). The majority (59 %, n = 180/305) were female students. The mean age was 24.5 years and 79.9 % (n = 243/304) owned a smartphone or tablet computer. Regarding the usage of the provided application, 2.3 % (n = 7/303) did not use the app while 68.0 % (n = 206/303) replied to have used it more than five times. Frequent users significantly differed from non-frequent users with regard to being female rather than male, higher mobile device ownership, more frequent exchange about obtaining the course certificate, higher personal interest in new technologies, larger enjoyment of the technology, lower intention to not use smartphone applications in the future, better opinion towards smartphone applications for the profession of a doctor, higher perceived importance of medical applications on the job, higher compatibility of smartphone applications with personal work style, higher perceived relevance of university support and personal benefit of use.

    2013-12-01

    A recent workshop sponsored by SERC-On the Cutting Edge brought together science educators from a range of schools across the country to discuss new approaches in teaching oceanography. In discussing student interest in our classes, we were struck by the fact that students are drawn to emotional or controversial topics such as whale hunting and tsunami hazard and that these kinds of topics are a great vehicle for introducing more complex concepts such as wave propagation, ocean upwelling and marine chemistry. Thus, we have developed an approach to introductory oceanography that presents students with real-world issues in the ocean sciences and requires them to explore the science behind them in order to improve overall ocean science literacy among non-majors and majors at 2 and 4 year colleges. We have designed a project-based curriculum built around topics that include, but are not limited to: tsunami hazard, whale migration, ocean fertilization, ocean territorial claims, rapid climate change, the pacific trash patch, overfishing, and ocean acidification. Each case study or project consists of three weeks of class time and is structured around three elements: 1) a media analysis; 2) the role of ocean science in addressing the issue; 3) human impact/response. Content resources range from textbook readings, popular or current print news, documentary film and television, and data available on the world wide web from a range of sources. We employ a variety of formative assessments for each case study in order to monitor student access and understanding of content and include a significant component of in-class student discussion and brainstorming guided by faculty input to develop the case study. Each study culminates in summative assessments ranging from exams to student posters to presentations, depending on the class size and environment. We envision this approach for a range of classroom environments including large group face-to-face instruction as well as hybrid

    IBM has created a general purpose, data-agnostic solution that provides high performance, low data latency, high availability, scalability, and persistent access to the captured data, regardless of source or type. This capability is hosted on commercially available cloud environments and uses much faster, more efficient, reliable, and secure data transfer protocols than the more typically used FTP. The design incorporates completely redundant data paths at every level, including at the cloud data center level, in order to provide the highest assurance of data availability to the data consumers. IBM has been successful in building and testing a Proof of Concept instance on our IBM Cloud platform to receive and disseminate actual GOES-16 data as it is being downlinked. This solution leverages the inherent benefits of a cloud infrastructure configured and tuned for continuous, stable, high-speed data dissemination to data consumers worldwide at the downlink rate. It also is designed to ingest data from multiple simultaneous sources and disseminate data to multiple consumers. Nearly linear scalability is achieved by adding servers and storage.The IBM Proof of Concept system has been tested with our partners to achieve in excess of 5 Gigabits/second over public internet infrastructure. In tests with live GOES-16 data, the system routinely achieved 2.5 Gigabits/second pass-through to The Weather Company from the University of Wisconsin-Madison SSEC. Simulated data was also transferred from the Cooperative Institute for Climate and Satellites — North Carolina to The Weather Company, as well. The storage node allocated to our Proof of Concept system as tested was sized at 480 Terabytes of RAID protected disk as a worst case sizing to accommodate the data from four GOES-16 class satellites for 30 days in a circular buffer. This shows that an abundance of performance and capacity headroom exists in the IBM design that can be applied to additional missions.

    2010-12-01

    In a time when domestic and foreign policy is becoming increasingly dependent on a robust understanding of scientific concepts (especially in regards to climate science), it is of vital importance that non-specialist students taking geoscience courses gain an understanding not only of Earth system processes, but also of how to discern scientific information from "spin". An experimental introductory level environmental geology course was developed at the Glendale Community College in Glendale, Arizona, in the fall of 2010 that sought to integrate collaborative learning, online resources, and science in the media. The goal of this course was for students to end the semester with not just an understanding of basic Earth systems concepts, but also with a set of tools for evaluating information presented by the media. This was accomplished by integrating several online sites that interface scientific data with popular web tools (ie, Google Maps) and collaborative exercises that required students to generate ideas based on their observations followed by evaluation and refinement of these ideas through interactions with peers and the instructor. The capstone activity included a series of homework assignments that required students to make note of science-related news stories in the media early in the semester, and then gradually begin critically evaluating these news sources, which will become their primary source of post-college geoscience information. This combination of activities will benefit students long after the semester has ended by giving them access to primary sources of scientific information, encouraging them to discuss and evaluate their ideas with their peers, and, most importantly, to critically evaluate the information they receive from the media and their peers so that they can become more scientifically literate citizens.

  17. Impact of SCALE-UP on science teaching self-efficacy of students in general education science courses

    Cassani, Mary Kay Kuhr

    The objective of this study was to evaluate the effect of two pedagogical models used in general education science on non-majors' science teaching self-efficacy. Science teaching self-efficacy can be influenced by inquiry and cooperative learning, through cognitive mechanisms described by Bandura (1997). The Student Centered Activities for Large Enrollment Undergraduate Programs (SCALE-UP) model of inquiry and cooperative learning incorporates cooperative learning and inquiry-guided learning in large enrollment combined lecture-laboratory classes (Oliver-Hoyo & Beichner, 2004). SCALE-UP was adopted by a small but rapidly growing public university in the southeastern United States in three undergraduate, general education science courses for non-science majors in the Fall 2006 and Spring 2007 semesters. Students in these courses were compared with students in three other general education science courses for non-science majors taught with the standard teaching model at the host university. The standard model combines lecture and laboratory in the same course, with smaller enrollments and utilizes cooperative learning. Science teaching self-efficacy was measured using the Science Teaching Efficacy Belief Instrument - B (STEBI-B; Bleicher, 2004). A science teaching self-efficacy score was computed from the Personal Science Teaching Efficacy (PTSE) factor of the instrument. Using non-parametric statistics, no significant difference was found between teaching models, between genders, within models, among instructors, or among courses. The number of previous science courses was significantly correlated with PTSE score. Student responses to open-ended questions indicated that students felt the larger enrollment in the SCALE-UP room reduced individual teacher attention but that the large round SCALE-UP tables promoted group interaction. Students responded positively to cooperative and hands-on activities, and would encourage inclusion of more such activities in all of the

    Meyer, Patrick Gerard

    This study examines college student understanding of key concepts that will support future organic chemistry success as determined by university instructors. During four one-hour individual interviews the sixteen subjects attempted to solve general chemistry problems. A think-aloud protocol was used along with a whiteboard where the students could draw and illustrate their ideas. The protocols for the interviews were adapted from the Covalent Structure and Bonding two-tiered multiple choice diagnostic instrument (Peterson, Treagust, & Garnett, 1989) and augmented by the Geometry and Polarity of Molecules single-tiered multiple choice instrument (Furio & Calatayud, 1996). The interviews were videotaped, transcribed, and coded for analysis to determine the subjects' understanding of the key ideas. The subjects displayed many misconceptions that were summarized into nine assertions about student conceptualization of chemistry. (1) Many students misunderstand the location and nature of intermolecular forces. (2) Some think electronegativity differences among atoms in a molecule are sufficient to make the molecule polar, regardless of spatial arrangement. (3) Most know that higher phase change temperatures imply stronger intermolecular attractions, but many do not understand the difference between covalent molecular and covalent network substances. (4) Many have difficulty deciding whether a molecule is polar or non-polar, often confusing bilateral symmetry with spatial symmetry in all three dimensions. (5) Many cannot reliably draw correct Lewis structures due to carelessness and overuse of flawed algorithms. (6) Many are confused by how electrons can both repel one other and facilitate bonding between atoms via orbitals---this seems oxymoronic to them. (7) Many cannot explain why the atoms of certain elements do not follow the octet rule and some believe the octet rule alone can determine the shape of a molecule. (8) Most do know that electronegativity and polarity

Acquire the diversified movement experience is a priority of physical education in junior school age. Students fourth grade of primary school - age 10-11 years, in the sensitive period for developing coordination and speed capabilities. Sports game handball and mode of the game "mini-handball", which is adapted to students age abilities and spatial characteristics of the majority of primary schools, abundant with various tasks, specifically dominated by natural forms of movement - running, jumping, throwing. Therefore, handball has a significant role in solving the tasks of physical education. The specific motor tests and relations with the general motor skills are particularly important for continuous monitoring of motor development of children. The survey was conducted on 79 boys fourth grade of primary school who participated in the electoral sport of handball in the regular physical education classes. The results of the handball test "ball slalom" and its relation with general motor skills of students fourth grade of primary school, should contribute to the perception of the value of handball as the content of physical education, but also to contribute to the selection and forecast performance of children in handball.

    Full Text Available Background: Primary health care in rural regions is currently undergoing a global crisis in respect of the next generation of practitioners. National and international recommendations advise placing greater emphasis upon practical skills and competences in medical studies. It is also in the interest of training the next generation to include mentoring and longitudinal integration of contact to teaching practices for general medicine in an early stage. Consequently, the (KAM was introduced in Halle in 2011 as an elective with 20 individually mentored students per year, beginning with the first subject-related semester. We are now reporting on the results of the evaluation for the first two years. Method: A standardised online survey was carried out with all students who took part in the KAM in the two years 2011 and 2012 (N=38. For both years the survey was made at the end of the first summer semester on the basis of an adapted version of the and the . Furthermore, each year the preference for the choice of specialty and location of a medical practice was queried. Predictors for the preference of the chosen specialty and the location of a medical practice were estimated by binary logistic regression analysis. Via univariate evaluations the number of students who reported an increase in knowledge in different areas of competence as a result of the KAM was counted. Correlations between the intention to remain in the KAM and the quality of teaching were evaluated on the basis of bivariate correlations. Results: 48% of the students agreed partly or fully that the KAM seminars enhanced their specialist competence. This individual acquiring of competence in the model project represented a significant predictor for the preferred choice of the area (OR 7.98; 95% CI [1.27-50.27], p=0.027. Students who assessed the commitment (r=0.504, support (r=0.526 and interaction management (r=0.529 of the mentors positively were more likely inclined to continue their

    To compare the prevalence of burnout and other forms of distress across career stages and the experiences of trainees and early career (EC) physicians versus those of similarly aged college graduates pursuing other careers. In 2011 and 2012, the authors conducted a national survey of medical students, residents/fellows, and EC physicians (≤ 5 years in practice) and of a probability-based sample of the general U.S. population. All surveys assessed burnout, symptoms of depression and suicidal ideation, quality of life, and fatigue. Response rates were 35.2% (4,402/12,500) for medical students, 22.5% (1,701/7,560) for residents/fellows, and 26.7% (7,288/27,276) for EC physicians. In multivariate models that controlled for relationship status, sex, age, and career stage, being a resident/fellow was associated with increased odds of burnout and being a medical student with increased odds of depressive symptoms, whereas EC physicians had the lowest odds of high fatigue. Compared with the population control samples, medical students, residents/fellows, and EC physicians were more likely to be burned out (all P prevalence of burnout, depressive symptoms, and recent suicidal ideation are relatively small. At each stage, burnout is more prevalent among physicians than among their peers in the U.S. population.

    Full Text Available Faculty members from the Department of Pathology at The University of Arizona College of Medicine-Tucson have offered a 4-credit course on enhanced general pathology for graduate students since 1996. The course is titled, “Mechanisms of Human Disease.” Between 1997 and 2016, 270 graduate students completed Mechanisms of Human Disease. The students came from 21 programs of study. Analysis of Variance, using course grade as the dependent and degree, program, gender, and year (1997-2016 as independent variables, indicated that there was no significant difference in final grade (F = 0.112; P = .8856 as a function of degree (doctorate: mean = 89.60, standard deviation = 5.75; master’s: mean = 89.34, standard deviation = 6.00; certificate program: mean = 88.64, standard deviation = 8.25, specific type of degree program (F = 2.066, P = .1316; life sciences: mean = 89.95, standard deviation = 6.40; pharmaceutical sciences: mean = 90.71, standard deviation = 4.57; physical sciences: mean = 87.79, standard deviation = 5.17, or as a function of gender (F = 2.96, P = .0865; males: mean = 88.09, standard deviation = 8.36; females: mean = 89.58, standard deviation = 5.82. Students in the physical and life sciences performed equally well. Mechanisms of Human Disease is a popular course that provides students enrolled in a variety of graduate programs with a medical school-based course on mechanisms of diseases. The addition of 2 new medically oriented Master of Science degree programs has nearly tripled enrollment. This graduate level course also potentially expands the interdisciplinary diversity of participants in our interprofessional education and collaborative practice exercises.

    2005-07-01

    This study investigated the effects of classwide peer tutoring (CWPT) on the acquisition, maintenance, and generalization of science vocabulary words and definitions. Participants were 14 seventh grade students at-risk for failure in a general education science course; 3 students had learning disabilities and 2 had a communication disorder. CWPT was conducted daily for 20 minutes during the last period of the school day. Procedures for CWPT were consistent with the Ohio State University CWPT model. Students were engaged in dyadic, reciprocal tutoring. Tutors presented word cards to tutees to identify the word and definition. Tutors praised correct responses and used a correction procedure for incorrect responses. After practicing their vocabulary words, students completed a daily testing procedure and recorded and plotted data. Many of the study's findings are consistent with previous studies using CWPT to teach word identification. Results of this study indicate a functional relationship between CWPT and acquisition of science vocabulary. All students were able to acquire words and definitions. Results for maintenance and generalization varied. When acquisition criterion was changed, maintenance and generalization scores increased for some students, while other students remained consistently high. All students reported that they enjoyed CWPT, and all but student stated it helped them learn science vocabulary.

  12. Determining Stressors among Dentistry Students of Tabriz University of Medical Sciences in Educational Environments and its Relationship with their General Health Condition

    Full Text Available Background: It is believed that medical students are more faced with stressors during their academic studies. The highest rate of stress and anxiety in clinical education settings may negatively affect the learning and success of these students. The aim of the current study is investigating the stressors dentistry students face within educational settings and its relationship with their general health condition. Materials and Methods: The current statistical-analytic study performed upon 180 dentistry students of Tabriz University of Medical Sciences in 2014. A 54-item Student Stressors Questionnaire was used to assess the students stress and a 28-item Goldberg Questionnaire was used to evaluate the general health of the students. Likert 4-item scale (0 to 3 was used for scoring both questionnaires. Results: Mean age of the participants was 24.37±2.84. 6.65% of students were female and the mean stress level was 1.2±0.6. 36.7%, 48.3% and 15% of students had low, average and high stress level, respectively. There was no significant relationship between students’ stress and sex or their marital status. 50%, 23.3%, 20.6% and 6.1% of students had high, average, poor and very poor general health, respectively. There was no significant relationship between students’ gender and their general health. There was also no significant relationship between students’ stress and their general health. Conclusion: Almost half of dentistry students had average stress and 15% had high stress in which levels its pressure may get sever with increased academic period and difficulty level of the academic units. Correct educational programs, periodic counseling meetings and use of skilled counselors at universities can play influential roles to reduce stress level of dentistry students.

    2010-11-01

    Full Text Available Emotional Intelligence, the ability to be aware of, understand, and express oneself, the ability to be aware of, understand, and relate to others, the ability to deal with strong emotions, and the ability to adapt to change and solve problems of a social or personal nature, can be considered an important factor in learning a language as it enhances the verbal fluency which is the ultimate goal in FLL. The present study intended to consider the relationship between emotional intelligence and academic performance in Osku-Iran Islamic Azad University`s EFL classes. For this purpose, 110 undergraduate EFL sophomore and junior students participated in this study. First, in the middle of the term they were required to complete Bar-On (1997 Emotional Intelligence Inventory and their EI scores were computed based on the guidelines Bar-On (1997 provided. At the end of the term the academic course final exam was administered to the students to achieve their academic mean score which was computed out of 20. After that the degree of correlation between EI and academic mean score was found. It became evident that there is no meaningful relationship between total EI score and academic mean score but there is a meaningful and positive relationship between some sub-scales of emotional intelligence and academic mean score. Therefore, material developers and syllabus designers are required to take emotional factors into account when they want to design syllabuses or make materials ready for teaching.

    To examine the associations between life satisfaction, loneliness, general health and depression among 172 medical students in Malaysia. Participants completed a questionnaire battery, which included the 12-item General Health Questionnaire, Beck's Depression Inventory, the Revised UCLA Loneliness Scale and the Satisfaction With Life Scale. Life satisfaction was negatively and significantly correlated with suicidal attitudes, loneliness and depression; and positively with health, which was negatively and significantly correlated with depression and loneliness. Self-concept was negatively correlated with loneliness and depression, depression was positively and significantly correlated with loneliness. Mediational analyses showed that the effects of loneliness and life dissatisfaction on depression were fully mediated by health. Even though less satisfied, and particularly lonelier, individuals are more likely to report higher levels of depression, this is only the case because both higher loneliness and life dissatisfaction are associated with poorer health. These results are discussed in terms of their implications for the diagnosis and treatment of mental health disorders in developing nations.

  20. Forces in general relativity

    International Nuclear Information System (INIS)

    Ridgely, Charles T

    2010-01-01

    Many textbooks dealing with general relativity do not demonstrate the derivation of forces in enough detail. The analyses presented herein demonstrate straightforward methods for computing forces by way of general relativity. Covariant divergence of the stress-energy-momentum tensor is used to derive a general expression of the force experienced by an observer in general coordinates. The general force is then applied to the local co-moving coordinate system of a uniformly accelerating observer, leading to an expression of the inertial force experienced by the observer. Next, applying the general force in Schwarzschild coordinates is shown to lead to familiar expressions of the gravitational force. As a more complex demonstration, the general force is applied to an observer in Boyer-Lindquist coordinates near a rotating, Kerr black hole. It is then shown that when the angular momentum of the black hole goes to zero, the force on the observer reduces to the force on an observer held stationary in Schwarzschild coordinates. As a final consideration, the force on an observer moving in rotating coordinates is derived. Expressing the force in terms of Christoffel symbols in rotating coordinates leads to familiar expressions of the centrifugal and Coriolis forces on the observer. It is envisioned that the techniques presented herein will be most useful to graduate level students, as well as those undergraduate students having experience with general relativity and tensor analysis.

  1. Beyond the "science of sophomores": does the rational choice explanation of crime generalize from university students to an actual offender sample?

    2008-12-01

    Much of the criminological literature testing rational choice theory has utilized hypothetical scenarios presented to university students. Although this research generally supports rational choice theory, a common criticism is that conclusions from these studies may not generalize to samples of actual offenders. This study proceeds to examine this issue in two steps. First, a traditional sample of university students is examined to determine how various costs and benefits relate to their hypothetical likelihood of offending. Then the same data collection procedures are employed with a somewhat different sample of younger, adjudicated, and institutionalized offenders to determine whether the conclusions drawn from the student sample generalize to this offender sample. Results generally suggest that the content and process of hypothetical criminal decision making differ in the sample of known offenders relative to the university students. Limitations of the current study, as well as suggestions for future research, are discussed.

    This cross-cultural study compared explanations of sleep paralysis (SP) in two countries and two groups with different levels of education in one country. Comparisons were made between individuals having experienced SP at least once in a lifetime from Cairo, Egypt (n = 89), Copenhagen, Denmark (n = 59), and the American University in Cairo, Egypt (n = 44). As hypothesized, participants from the general Egyptian population were more likely to endorse supernatural causal explanation of their SP compared to participants from Denmark; participants from the American University in Cairo were less likely to endorse supernatural causes of their SP compared to participants from the general Egyptian population. Moreover, participants from the American University in Cairo were marginally significantly more likely to endorse supernatural causes of their SP compared to participants from Denmark. Additionally, we explored which culturally bound explanations and beliefs about SP existed in Egypt and Denmark. We found that nearly half (48%) of the participants from the general Egyptian population believed their SP to be caused by the Jinn, a spirit-like creature with roots in Islamic tradition, which constitutes a culturally bound interpretation of the phenomenology of SP in this region of the world. Case studies are presented to illustrate these findings.

    Personal mission in life can determine the motivation, happiness, career advancement and fulfilment in life of the medical students (MSs) along with improvement in professional/clinical performance of the family physicians. This study explored the personal beliefs, values and goals in the lives of MSs and general practitioners (GPs). Fourth-year MSs at the Universiti Putra Malaysia and GPs who participated in a 2-hour session on 'Ethics in Family Medicine' in 2012 were invited. All the participants submitted the post-session written reflections about their personal missions in life. The written reflections were analysed using thematic analysis. A total of 87 MSs and 31 GPs submitted their written reflections. The authors identified 17 categories from the reflections contained by four themes-good vs. smart doctor, professional improvement vs. self-improvement, self-fulfilment and expressed motivation. The most common categories were "to be a good doctor" (97/330) and "professional improvement" (65/330). Many MSs had expressed motivation and wanted to be a smart doctor as compared to the GPs, whereas a larger number of GPs wished to have a fulfilled life and be a good doctor through professional improvement. The difference between the two student groups might indicate different levels of maturity and life experiences. Medical teachers should engage students more effectively in orientating them towards the essential values needed in medical practice.

    2017-01-01

    To quantify the prevalence of obesity and obesity-related factors (dietary behaviors and physical activity levels) in a cross-sectional, observational study of ASEAN undergraduate students. A total of 6783 (35.5% male and 64.5% female) undergraduate students (Mean age: 20.5, SD = 2.0) from eight ASEAN countries completed questionnaires and anthropometric measurements. Multivariable logistic regression was used to estimate odds ratios (ORs) for the association of nutrition behaviors with prevalence of general obesity (body mass index ≥ 25 kg/m 2 ), elevated waist-to-height ratio (WHtR) (>0.50), and high waist circumference (WC) (≥80 cm in females, ≥90 cm in males). Covariates included sociodemographic factors, dietary behavior, physical activity and sitting time (using the "International Physical Activity Questionnaire"). There was a higher prevalence of general obesity (24.2% versus 9.3%), and high WHtR (16.6% versus 12.1) in males relative to females, while high WC (9.4% versus 10.4%) did not significantly differ between genders. In multivariable logistic regression analyses, compared to females, males had higher odds of obesity (odds-ratio, OR: 2.13, confidence interval, CI: 1.80, 2.77), and high WHtR (OR: 1.90, CI: 1.48, 2.43) ( P ASEAN young adults. Specific dietary behaviors but not physical activity nor sedentary behavior were associated with obesity.

    2005-09-01

    This is a variation on the String and Sticky Tape demonstration "The Wave Game," suggested by Ron Edge. A group of students stand side by side, each one holding a card chest high with both hands. The teacher cues the first student to begin raising and lowering his card. When he starts lowering his card, the next student begins to raise his. As succeeding students move their cards up and down, a wave such as that shown in the figure is produced. To facilitate the process, students' motions were synchronized with the ticks of a metronome (without such synchronization it was nearly impossible to generate a satisfactory wave). Our waves typically had a frequency of about 1 Hz and a wavelength of around 3 m. We videotaped the activity so that the students could analyze the motions. The (17-year-old) students had not received any prior instruction regarding wave motion and did not know beforehand the nature of the exercise they were about to carry out. During the activity they were asked what a transverse wave is. Most of them quickly realized, without teacher input, that while the wave propagated horizontally, the only motion of the transmitting medium (them) was vertical. They located the equilibrium points of the oscillations, the crests and troughs of the waves, and identified the wavelength. The teacher defined for them the period of the oscillations of the motion of a card to be the total time for one cycle. The students measured this time and then several asserted that it was the same as the wave period. Knowing the length of the waves and the number of waves per second, the next step can easily be to find the wave speed.

    Demonstrating competence in clinical skills is key to course completion for medical students. Methods of providing clinical instruction that foster immediate learning and potentially serve as longer-term repositories for on-demand revision, such as online videos demonstrating competent performance of clinical skills, are increasingly being used. However, their impact on learning has been little studied. The aim of this study was to determine the value of adjunctive on-demand video-based training for clinical skills acquisition by medical students in endocrinology. Following an endocrinology clinical tutorial program, 2nd year medical students in the pre-assessment revision period were recruited and randomized to either a set of bespoke on-line clinical skills training videos (TV), or to revision as usual (RAU). The skills demonstrated on video were history taking in diabetes mellitus (DMH), examination for diabetes lower limb complications (LLE), and examination for signs of thyroid disease (TE). Students were assessed on these clinical skills in an observed structured clinical examination two weeks after randomization. Assessors were blinded to student randomization status. For both diabetes related clinical skills assessment tasks, students in the TV group performed significantly better than those in the RAU group. There were no between group differences in thyroid examination performance. For the LLE, 91.7% (n = 11/12) of students randomized to the video were rated globally as competent at the skill compared with 40% (n = 4/10) of students not randomized to the video (p = 0.024). For the DMH, 83.3% (n = 10/12) of students randomized to the video were rated globally as competent at the skill compared with 20% (n = 2/10) of students not randomized to the video (p = 0.007). Exposure to high quality videos demonstrating clinical skills can significantly improve medical student skill performance in an observed structured clinical examination of these skills, when

    Pressurized metered dose inhalers (pMDIs) remain important therapeutic options for obstructive lung diseases. The ability to instruct and evaluate inhaler technique is a crucial skill that all medical professionals should possess; unfortunately, many professionals lack proficiency with pMDIs. We aimed to determine if brief education interventions of differing modalities can positively affect medical students' skills over the long term. The baseline ability of medical students and first year residents to use pMDIs was scored via a 10-point scoring system. Students were randomized to receive no education, one-on-one instruction, or video instruction. Students were then retested immediately after the education and at the 3-month mark for retention of acquired skills. Video, one-on-one and the placebo groups modalities statistically improved the average medical student's score in the immediate retesting (7.5 and 7.4 vs. 4.7, p grades at the immediate recall significantly improved for both modalities. During retention testing, only video education had a statistically significant improvement in pass rate over the control group, as defined by an average score of 7 or better (8 vs. 1, p improve medical students' ability to use pMDIs in short-term testing. However, only video education retained significant improvement compared with control after 3 months. This suggests that compared with traditional one-on-one teaching, video education is an effective means of teaching medical students how to improve their pMDI technique.

    Full Text Available The problem of education of the individuality through the culture with the help of development of value potential in physical culture is discussed in the article. Improving the efficiency of education of medical students is becoming the leading aim of high school, which is connected with the development of culture of thinking, imagination, feelings and human creativity. Development of human motor capabilities is inseparable from the development of his personal qualities in physical education. One of the most important tasks of the educational process at high school is providing the motivation of a healthy lifestyle, motivation for physical culture and sports. Promotion of a healthy lifestyle should go through the activation of incentive mechanisms and a number of other phenomena of the individual's inner world. Efficiency of this approach is that it provides activity of a person in questions connected with preservation of individual and public health. The article tells us about the need to develop programs that can promote future professionals to form healthy and productive lifestyle, sustained motivation to permanent physical self-improvement. The problem can be successfully solved in the process of learning such course as «Physical education».

    This study builds on previous research on predictors of depression and anxiety in veterinary medical students and reports data on three veterinary cohorts from two universities through their first three semesters of study. Across all three semesters, 49%, 65%, and 69% of the participants reported depression levels at or above the clinical cut-off, suggesting a remarkably high percentage of students experiencing significant levels of depression symptoms. Further, this study investigated the relationship between common stressors experienced by veterinary students and mental health, general health, and academic performance. A factor analysis revealed four factors among stressors common to veterinary students: academic stress, transitional stress, family-health stress, and relationship stress. The results indicated that both academic stress and transitional stress had a robust impact on veterinary medical students' well-being during their first three semesters of study. As well, academic stress negatively impacted students in the areas of depression and anxiety symptoms, life satisfaction, general health, perception of academic performance, and grade point average (GPA). Transitional stress predicted increased depression and anxiety symptoms and decreased life satisfaction. This study helped to further illuminate the magnitude of the problem of depression and anxiety symptoms in veterinary medical students and identified factors most predictive of poor outcomes in the areas of mental health, general health, and academic performance. The discussion provides recommendations for considering structural changes to veterinary educational curricula to reduce the magnitude of academic stressors. Concurrently, recommendations are suggested for mental health interventions to help increase students' resistance to environmental stressors.

    Full Text Available The paper empirically tests the assumption that parents' perspective and teachers' perspective in the situation of cooperation are generated from the guiding action of general beliefs of both about their role and the conditions of its fulfillment in the existing everyday working and living conditions. The research sample consists of 270 respondents who were divided into three subsamples (170 teachers, 60 parents/teachers, 40 parents by the research draft. For the purposes of the research, three varieties (with respect to the three aspects of respondent's role of the same questionnaire (isomorphic open-ended questions, narrative answers were created. The questions were thematised around the way teachers and parents observe difficulties in functioning, each from their own role, the way they determine their causes and consequences, and the kinds of support resources they use in the endeavors to cope with difficulties. The results indicate that the difficulty reported by parents to be conditioned by systemic factors (the lack of time for children due to providing work and money gains the status of external/systemic causes of degradation of educational values in teachers' beliefs (delegating responsibility to parents for systemic difficulties, which can pose a significant obstacle to relational understanding. The finding points out to the importance of developing the skill of change of perspective in teachers in order to achieve coordination of differences in beliefs and develop an internal framework of mutual understanding.

    An elevated resting heart rate (Rhr) has been linked with adverse cardiovascular outcomes. Obese people have altered autonomic balance that could lead to elevated Rhr and altered responses to postural changes. As no comparative data are available on Rhr in young normal weight (NW) and obese (OB) adults in Saudi Arabia, the present study was aimed at finding out the effect of adiposity on RHR and RHR response to change in posture. Methods: Second-year male students (n=231; age:19-20 years), were recruited from the Dammam University, Dammam, Saudi Arabia, during the period September 2008 to October 2009. Anthropometric measures were obtained and indices of obesity (body mass index [EMI], waist circumference [WC], waist-to-hip ratio [WHR], waist-to-stature ratio [WSR]) were calculated. RHR in standing and supine positions were obtained from radial pulse. Pearson's correlation (r) between obesity indices and RHR as well as the differences between RHR in NW and OB groups were calculated. Results: General obesity (BMI greater or equal to 25.0 kg/m1 was found in 45.5% students. Central obesity (WC>85 cm or WSR>50.0) was found in 36.8% students. RHR was significantly correlated with BMI, WC and WSR (r=O.305, 0.300, 0.299 respectively, p< O.01) . Subjects above the obesity indices cut-off points had significantly higher values of RHR in both standing and supine positions compared to NW individuals (p<0.05). There was a greater reduction in RHR on changing the posture to supine state in OB group. Conclusion: A significantly higher RHR and a greater change in RHR on changing the posture point towards an altered autonomic balance in OB group of young adolescent males. This underscores the need to implement health education program to combat obesity at school and college levels. (author)

    We aimed to quantify associations between drinking and mental well-being, self-esteem and general self-efficacy among New Zealand university students approaching graduation. A web-based survey was conducted across all eight New Zealand universities in 2011. Participants were enrolled in their final year of a bachelor degree or a higher qualification and were aged 25 years and under (n = 5082, response level 65 %). Measures included the Alcohol Use Disorders Identification Test-Consumption, Warwick-Edinburgh Mental Well-being Scale, and items from the Rosenberg Self-esteem Scale and General Self-efficacy Scale. Linear regression models were used to estimate associations between the psychological measures and (1) drinking patterns for all participants (abstention/moderate/hazardous); and (2) consumption indicators for non-abstaining participants (frequency/quantity/heavy drinking frequency), adjusting for a range of individual, social and personality characteristics, separately for men and women. Lower mental well-being was associated with a moderate or hazardous drinking pattern for men, and a hazardous pattern for women, compared to abstaining participants. Higher self-esteem was associated with any level of heavy drinking frequency for men, while the heaviest drinking women had a pattern of lower self-esteem. There was a general pattern of higher general self-efficacy for men and women who drank alcohol. We observed that higher levels of drinking were associated with small, yet statistically significant, differences in psychological outcomes for men and women. Our findings are of uncertain clinical significance; however, they underscore the importance of investigating a fuller range of social and personality factors that may confound the association of drinking and psychological outcomes.

    Project LITE (Light Inquiry Through Experiments) is a materials, software, and curriculum development project. It focuses on light, optics, color and visual perception. According to two recent surveys of college astronomy faculty members, these are among the topics most often included in the large introductory astronomy courses. The project has aimed largely at the design and implementation of hands-on experiences for students. However, it has also included the development of lecture demonstrations that employ novel light sources and materials. In this presentation, we will show some of our new lecture demonstrations concerning geometrical and physical optics, fluorescence, phosphorescence and polarization. We have developed over 200 Flash and Java applets that can be used either by teachers in lecture settings or by students at home. They are all posted on the web at http://lite.bu.edu. For either purpose they can be downloaded directly to the user's computer or run off line. In lecture demonstrations, some of these applets can be used to control the light emitted by video projectors to produce physical effects in materials (e.g. fluorescence). Other applets can be used, for example, to demonstrate that the human percept of color does not have a simple relationship with the physical frequency of the stimulating source of light. Project LITE is supported by Grant #DUE-0125992 from the NSF Division of Undergraduate Education.

    In 2008-09, the National Health Systems Resource Center of India reported overall quality of nurse-midwifery education in Bihar as grossly sub-optimal. To address this, we implemented a competency-based training using virtual classrooms in two general nurse midwives (GNM) schools of Bihar. The students from remotely located nursing institutions were now able to see live demonstrations of maternal and newborn health (MNH) practices performed by a trained faculty on simulation models at instructor location. To evaluate the effectiveness of virtual classroom training in improving the MNH-related skills of the nursing-midwifery students in Bihar, India. This study used a pre- and post-intervention design without a control group. Students from two public GNM schools of Bihar. Final-year students from both the GNM schools who have completed their coursework in MNH. A total of 83 students from selected GNM schools were assessed for their competencies in six key MNH practices using objective structured clinical examination method prior to intervention. A 72hour standardized training package was then implemented in these schools through virtual classroom approach. Post-intervention, 92 students from the next batch who attended virtual training were assessed for the same competencies. The mean student score assessed before the intervention was 21.3 (95% CI, 19.9-22.6), which increased to 62.0 (95% CI, 60.3-63.7) post-intervention. This difference was statistically significant. When adjusted for clustering using linear regression analysis, the students in post-intervention scored 52.3 (95% CI, 49.4%-55.3%) percentage points higher than pre-intervention, and this was statistically significant. Virtual classroom training was found to be effective in improving knowledge and key MNH skills of GNM students in Bihar, India. Copyright © 2015. Published by Elsevier Ltd.

    Full Text Available The authorities claim that music training helps children and young people gain insight and actualize themselves and it contributes to their self-expression, self-confidence and socialization process. As known, music education that children and adolescences get varies for several reasons, and particularly the aims, the ways, and the intensity of courses differ according to the school types. From this context, the students of the high schools of fine arts getting vocational musical training and the students of general high schools not getting the vocational training were investigated by means of a general personality inventory, and a research was conducted to examine whether or not music education supports the personality development of the high school students. In the study, 140 students attending the last grade of high schools of fine arts, 140 students attending last grade of general high schools with total amount of 280 were randomly selected. The students were administered a 168 item personality inventory to determine their characteristics of ‘social, personal and general adaptation’ levels. Following findings were obtained as a result of the survey: When the total scales “general adaptation”, “social adaptation” and “personal adaptation” levels, including the sub-scales of ‘family affairs, social affairs, social norms, anti-social tendencies’, ‘self-actualization, emotional decisiveness, neurotic tendencies and psychotic symptoms’, were examined, the scores of students who get vocational music training were found significantly higher than the students who do not get it. The results of the study show that music training supports the personality development of adolescences positively.

El objetivo del artículo es valorar la evolución histórica del proceso educativo de los escolares sordos y las tendencias en la educación de la sexualidad de estas personas en el contexto educativo de Cuba. El análisis tendencial fue realizado tomando como indicadores a los referentes relacionados con la evolución teórica respecto al proceso educativo de las personas sordas en general; los criterios relativos a la educación de la sexualidad de las personas con necesidades educativas especiales, particularizando en los escolares sordos; la incorporación de los contenidos relativos al tema de la sexualidad a los planes de estudio y la adecuación de estos objetivos y contenidos a las particularidades de los escolares sordos. Se constató que se ha transitado desde una etapa donde no se abordaba el tema, pasando por una fase biologicista hasta concebirla como un proceso educativo esencial en la formación de la personalidad en su condición de sujetos bilingües y biculturales. The study of the evolution of deaf students’ sexuality as a component of the individual personality is possible by systematizing experiences in its corresponding educative process. This paper is aimed at evaluating the historical evolution of the education of deaf students and the main trends in their sexuality education. This study was carried on the basis of the following indicators: theoretical framework underlying the educative process of deaf people; criteria related to sexual education of handicaps, particular deaf people, and inclusion of sexuality related topics in the curriculum. The findings lead to clear up that the main trends formerly ignore such contents, some years later it takes a biolistic approach and lately assumes them as component of individual

    Ghatty, Sundara L.

    Over the past decade, there has been a dramatic rise in online delivery of higher education in the United States. Recent developments in web technology and access to the internet have led to a vast increase in online courses. For people who work during the day and whose complicated lives prevent them from taking courses on campus, online courses are the only alternatives by which they may achieve their goals in education. The laboratory courses are the major requirements for college and university students who want to pursue degree and certification programs in science. It is noted that there is a lack of laboratory courses in online physics courses. The present study addressed the effectiveness of a virtual science laboratory in physics instruction in terms of learning outcomes, attitudes, and self-efficacy of students in a Historically Black University College. The study included fifty-eight students (36 male and 22 female) of different science majors who were enrolled in a general physics laboratory course. They were divided into virtual and traditional groups. Three experiments were selected from the syllabus. The traditional group performed one experiment in a traditional laboratory, while the virtual group performed the same experiment in a virtual laboratory. For the second experiment, the use of laboratories by both groups was exchanged. Learner's Assessment Test (LAT), Attitudes Toward Physics Laboratories (ATPL), and Self-Efficacy Survey (SES) instruments were used. Additionally, quantitative methods such as an independent t-test, a paired t-test, and correlation statistics were used to analyze the data. The results of the first experiment indicated the learning outcomes were higher in the Virtual Laboratory than in the traditional laboratory, whereas there was no significant difference in learning outcomes with either type of lab instruction. However, significant self-efficacy gains were observed. Students expressed positive attitudes in terms of liking

    The cabin safety demonstration on board an aircraft is one of the methods to provide safety information for passengers before aircraft takeoff. However, passengers' enthusiasm toward safety demonstrations is normally low. Therefore, the study of passengers' perception toward safety briefings on board an aircraft is important in increasing the safety awareness for the travelling public on commercial aircraft. A survey was distributed to measure the perceptions of Middle Tennessee State University (MTSU) faculty and staff, Aerospace students, and international students who have traveled in the last year. It was generally found that watching the cabin safety demonstration before aircraft takeoff was believed to be important for passengers. However, the attention to the safety demonstration remained low because the safety briefings were not good enough in terms of clear communication, particularly in the recorded audio demonstration and the live safety demonstration methods of briefing.

    In medical education and practice, smartphone apps are increasingly becoming popular. In general practice, apps could play an important future role in supporting medical education and practice. To explore medical students' perceptions regarding the potential of a general practice app for training and subsequent work as a physician. Cross-sectional survey among Leipzig fourth-year medical students who were provided with an app prototype for a mandatory general practice course. Response rate was 99.3% (n = 305/307); 59.0% were female and mean age was 24.5 years. Students certified that the app had a higher potential than textbooks in both education (57.4% vs. 18.0%) and practice (47.1% vs. 22.8%). Students' most desired possible app extensions when anticipating its use for subsequent work as a physician were looking up information for diagnostics, therapy and prediction (85.1%), access to electronic patient files (48.1%), communication and networking (44.3%), organization of medical training (42.9%) and online monitoring of patients (38.1%). Students experienced with medical smartphone apps were more interested in app extensions. Consideration to use the app to support the opening of their own practice was significantly associated with higher interest in accessing electronic patient files, networking with colleagues and telemedicine. Fourth year medical students from Leipzig see a high potential in smartphone apps for education and practice and are interested in further using the technology after undergraduate education.

    This study examined the effectiveness of three sets of school-based instructional materials and community training on acquisition and generalization of a community laundry skill by nine students with severe handicaps. School-based instruction involved artificial materials (pictures), simulated materials (cardboard replica of a community washing machine), and natural materials (modified home model washing machine). Generalization assessments were conducted at two different community laundromats, on two machines represented fully by the school-based instructional materials and two machines not represented fully by these materials. After three phases of school-based instruction, the students were provided ten community training trials in one laundromat setting and a final assessment was conducted in both the trained and untrained community settings. A multiple probe design across students was used to evaluate the effectiveness of the three types of school instruction and community training. After systematic training, most of the students increased their laundry performance with all three sets of school-based materials; however, generalization of these acquired skills was limited in the two community settings. Direct training in one of the community settings resulted in more efficient acquisition of the laundry skills and enhanced generalization to the untrained laundromat setting for most of the students. Results of this study are discussed in regard to the issue of school versus community-based instruction and recommendations are made for future research in this area.

Carter Journalism Institute at New York University has offered a series of basic and advanced writing workshops for graduate students and post-docs in NYU's eight scientific divisions (neuroscience, psychology, physics, biology, chemistry, mathematics, anthropology, and computer science). The basic methodology of the NYU approach will be described, along with successful examples of both written and radio work by students that have been either published or broadcast by general interest journalism outlets.

  1. Elementary General Education Teachers' Knowledge of and Experience Teaching Students with Disabilities in Science and Social Studies

    Science.gov (United States)

    Rice, Diane

    In Grades 3 to 5 at a suburban southeastern elementary school, the percentage of students with disabilities (SWDs) who do not meet state standards in science and social studies is greater than that of their nondisabled peers. To address this disparity, district administrators required that proficiency ratings increase for SWDs without providing general education (GE) teachers with training. A qualitative bounded case study was used to understand how GE teachers constructed their knowledge of and met SWDs instructional needs and to understand GE teachers' needs as they worked toward meeting the district goals. Piaget's constructivist learning theory served as the conceptual framework for this study. A purposeful sample of 6 GE teachers, 2 each from Grades 3-5 whose classrooms included SWDs, volunteered to participate in open-ended interviews. Qualitative data were analyzed using provisional coding and pattern coding. A primary finding was that the participants identified teacher collaboration and professional development necessary to accommodate SWDs in the GE setting. This finding led to a recommendation that school leaders provide ongoing professional development for GE teachers as well as ongoing opportunities for collaboration between GE and special education teachers. These endeavors may contribute to positive social change by providing GE teachers instructional strategies and accommodations for meeting the learning needs of SWDs to increase the number and percentage of SWDs who meet the state standards and district goals in science and social studies.

    Generalized Social Phobia (GSP) is a common anxiety disorder that produces clear social life disruptions. There is no consensus on the specific processes involved in its development, but the role of the hypothalamic-pituitary-adrenal (HPA) axis has been suggested. This study analyzed the effects of the cortisol response to the Trier Social Stress Test (TSST) on the memory retrieval of pictures with different emotional valences in 45 non-treated young students with GSP and 50 non-anxious (NA) subjects (mean=19.35years, SD=0.18). No differences were found in the cortisol response of GSP and NA subjects to the TSST and control sessions. In addition, psychosocial stress impaired memory retrieval in both the GSP and NA groups, with no differences between them. Regarding the sex factor, no effects were found in the cortisol response to the TSST. However, during the encoding session, GSP men had higher cortisol levels than GSP women and NA subjects. There was also a significant interaction between sex and stress exposure on memory retrieval. Women recognized more unpleasant and neutral pictures than men; however, under stress, the women's advantage disappeared, and the men's performance improved. Sex also interacted with social phobia on positive mood, with GSP women exposed to the TSST showing the lowest positive mood. These results suggest that GSP subjects do not present an HPA axis sensitization to psychosocial stress, and they emphasize the importance of Sex in understanding stress effects on memory.

    ChemPrep was developed to be a stand-alone preparatory short-course to help students succeed in general chemistry. It is Web-based and delivered using the OWL system. Students reported that the ChemPrep materials (short information pages, parameterized questions with detailed feedback, tutorials, and answers to questions through the OWL message system) permitted them to work independently without the need for textbook or lecture. On average, students who completed ChemPrep had higher grades in the subsequent GenChem, Nursing, and Honors chemistry courses, with a greater percentage achieving a grade of C- or higher. Participation in ChemPrep was voluntary, and more women than men responded. Students in the Honors course enrolled in ChemPrep in higher percentages than students in GenChem and Nursing. SAT and departmental math placement exam scores were used as proxy measures of prior achievement and ability. Based on these, Honors chemistry ChemPrep users were on par with their peers but performed better in the course than non-users. In GenChem and Nursing chemistry courses, ChemPrep helped students of high prior achievement and ability perform better than their achievement scores would predict. Weaker or less motivated students did not respond to the voluntary offerings of ChemPrep in the same numbers as stronger or more motivated students, and we are seeking alternate ways to reach this population.

    To investigate the perception of Oral and maxillofacial surgery by healthcare professionals, students and general public. A questionnaire form was created that listed ten clinical situations, and given by hand to 1200 individuals, divided into six groups: group 1, medical professionals; group 2, Specialties of dentistry; group 3, general dentists; group 4, medical students; group 5, dental students; and group 6, general public, each comprising 200 individuals. Respondents were asked to indicate who they would expect to treat them if they had one of the specified conditions listed in the questionnaire. We present the results and current awareness levels of this simple questionnaire. The present study addresses the common issue raised by many authors, 'What surgical education the speciality offers?' especially to medical professionals, medical students and general public to enhance an appropriate referral. Most of the respondents in groups 2, 3 and 5 agreed that specific conditions listed in the questionnaire were within the domain of oral and maxillofacial surgery, but such response was not seen in groups 1, 4 and 6 ( p  oral and maxillofacial surgery was found to be 50.2%. The onus of creating and improving the awareness and perception of our specialty lies on oral and maxillofacial surgeon. Unified efforts at individual as well as global level will help achieve this goal.

    2018-04-05

    The recent UK Government paper 'Five year forward view' describes the need to move much patient management from secondary to primary care, and this will require a significant increase in the numbers of General Practice Nurses (GPNs). Until recently, there has been no clear recruitment strategy to address this. There have however been a number of proposed solutions to address the impending GPN recruitment crisis and to increase the numbers of new GPNs in post. General Practitioners (GPs) working in the Advanced Training Practice Scheme (ATPS) have been commissioned by Health Education England to provide placements for student nurses. This paper reports upon the findings of a study evaluating the South Yorkshire ATPS network in relation to nursing students' perceptions of general practice as a placement and a potential career option post-graduation. Data were collected using semi-structured interviews with 18 nursing students. Qualitative data analysis used a framework approach and themes were cross-checked within the team. The research had ethical approval and anonymity and confidentiality were maintained throughout. Using the Communities of Practice (CoP) framework as a theoretical lens, two main themes emerged from the data: 'Myths and misunderstandings' outlined some of the misconceptions that abounded in the absence of an established CoP in general practice. These included perceptions of what constitutes a 'good' placement, an apparent lack of relevant content in the curriculum, and the widespread use of social media by students as a means of information gathering. 'Changing hearts and minds' referred to the need to positively influence the culture within general practice by addressing some of the longstanding myths. Through the fledgling CoP, the students' perceptions of the GPN role in particular were positively revised, as was the prospect of a career in general practice upon graduation. The CoP that is emerging through the ATPS placements appear to be

    The apparatus consists of a heavy object that is dragged steadily with an elastic cord. Although pulled with a constant velocity, the heavy object repeatedly slides and then stops. A small vibration sensor, attached to a computer display, graphically monitors this intermittent motion. 2 This intermittent sliding motion mimics the intermittent fault slippage that characterizes the earthquake fault zones. In tectonically active regions, the Earth's outer brittle shell, which is about 50 km thick, is slowly deformed elastically along active faults. As the deformation increases, stress also increases, until fault slippage releases the stored elastic energy. This process is called elastic rebound. Detailed instructions are given for assembly and construction of this demonstration. Included are suggested sources for the vibration sensor (geophone) and the computer interface. Exclusive of the personal computer, the total cost is between $125 and $150. I gave a talk at the Geological Society of America's Cordilleran Section Centennial meeting on June 2, 1999. The slides show how this table-top demonstration can be used to help meet many of the K-12 teaching goals described in Benchmarks for Science Literacy (American Association for the Advancement of Science, 1993).

    Workplace harassment, a known risk factor for adult drinking, is understudied in college samples, but may help explain observed gender differences in drinking patterns. We examine effects of sexual and generalized workplace harassment on changes in drinking behavior over the first semesters of college, and the extent to which these effects differ based on prematriculation drinking for men and women students. Data derive from two waves of a longitudinal study of eight Midwestern colleges and universities. Data were collected from 2080 employed students via a Web-based survey assessing sexual and generalized workplace harassment, stressful life events, drinking to intoxication, and binge drinking prior to freshman year (fall 2011) and approximately one year later (summer to fall 2012). At baseline, lifetime drinking status, frequency of alcohol consumption, and demographics were also assessed. Linear-mixed modeling indicated that employed women students who were frequent drinkers prematriculation were at risk for high levels of drinking associated with workplace harassment, while men who were nondrinkers were most at risk of increasing problem drinking over time when exposed to workplace harassment. Alcohol use prevention efforts directed towards employed students are needed both prior to and during college, to instruct students how to identify workplace harassment and cope in healthier ways with stressful workplace experiences. These efforts might be particularly useful in stemming problematic drinking among women who drink frequently prior to college, and preventing men who are nondrinkers upon college entry from initiating problematic drinking during subsequent enrollment years.

    Research from various countries consistently reported an advantage of boys over girls in general knowledge and was also suggestive of some overall trends regarding specific domains of general knowledge that were speculated to stem from biologically differentiated interests. However, results were heterogeneous and, as of yet, had not been evaluated meta-analytically. Moreover, previous research drew on overly homogeneous high-school or undergraduate samples whose representativeness appears problematic; mostly, likely moderators, such as school type, student age or parental education, were also not directly investigated or controlled for. We provide a meta-analytical aggregation of available results regarding sex differences in general knowledge and present new data, investigating the psychometric properties of the General Knowledge Test (GKT), on which previous research primarily relied, and explored sex differences in a large and heterogeneous Austrian high-school student sample (N = 1088). The aggregated sex effect in general knowledge was of medium size in previous research, but differences in specific domains were heterogeneous across countries and only modest at best. Large sex differences in our data could be explained to a large part by school-related moderators (school type, school, student age, parental education) and selection processes. Boys had a remaining advantage over girls that was only small in size and that was consistent with the magnitude of sex differences in general intelligence. Analysis of the GKT yielded no evidence of biologically differentiated interests, but of a specific interest in the humanities among girls. In conclusion, previous research likely overestimated sex differences in general knowledge.

  2. Relationships between Self-Efficacy and the Academic Procrastination Behaviour among University Students in Malaysia: A General Perspective

    Directory of Open Access Journals (Sweden)

    Zainudin Abu Bakar

    2016-08-01

    Full Text Available Procrastination behaviour is a common phenomenon among people. In educational setting it always related to the student academic performance. Past studies have shown that the tendency of student to procrastinate could affect their academic life. For example, studying in the last minute is a procrastination behaviour committed by the students. This study is conducted to explore the association between academic procrastination, self-efficacy and academic performance among university students in Malaysia. The finding showed that most students are prone to procrastinate in their academic life. However in most cases it appears that the procrastination behaviour does not affect the student’s academic performance. A similar situation also recorded where the self-efficacy does not affect the tendency for student to procrastinate in their academic activities. It is suggested that in improving the student performance at the university the direct and indirect factors should be addressed including the academic procrastination behaviours. It was concluded that the student’s academic performance is influenced not directly by procrastination behaviour but by other factors. Several suggestions and recommendations are also presented.

    There will be increasing competition for young physicians worldwide as more and more physicians retire. While enthusiasm towards GP work is important for GP teachers as role models, satisfaction within the profession has declined. This study aims to determine if medical students' desire to become GPs is related to the job satisfaction of their teaching GPs and explore the factors tied to this job satisfaction. In this cross-sectional, correlational study, teaching GPs of the University of Bern and the fourth year medical students completing internships with them filled in separate questionnaires. Whether or not the GP teacher is perceived by a student to be satisfied with her/his job is correlated to that student's satisfaction with the internship, which in turn, is correlated with student's wish to be a GP after the internship. Results show which factors are most related to GP job satisfaction and the effect of working hours and their composition. Medical students' perception of their GP teachers' job satisfaction positively affect their wish to become GPs, and their satisfaction with their internships adds to this. Enhancing the positive aspects of GP work, such as recognition, and improving negative ones, such as administrative duties, are necessary to attract medical students into the GP field.

    Admission to university is a very sensitive period of life for efficient, active, and young workforces in any country, and it is mostly associated with many changes in social and human relationships. These changes lead to anxiety in students. Moreover, humans need certain functions in order to adaptively deal with different life situations and challenges. By training stress management, these functions can help human acquire the required abilities. The present study was aimed at investigating the effectiveness of stress management training in anxiety, psychological hardiness, and general self-efficacy among university students. The study was a quasi-experimental intervention (pretest-posttest-follow-up) including a control group, it was a fundamental applied study. The statistical population consisted of all students of Islamic Azad University, Karaj, Iran. Convenient sampling was employed to select 30 students who were divided into an experimental group (n=15) and a control group (n=15). Before stress management training, both groups filled out Beck Anxiety Inventory, Long and Goulet scale of psychological hardiness, and General Self-efficacy Scale (GSE-10). Afterwards, the experimental group was provided with stress management training. And after the experiment, the abovementioned questionnaires and scales were responded by the two groups. Finally the collected data were analyzed and compared using one-way MANOVA. The results of MANOVA indicated that there was a significant difference between the two groups in terms of anxiety, hardiness, and general self-efficacy (pstress management among university students cause anxiety to drop; moreover, it enhances their psychological hardiness and self-efficacy. In regard with the role and importance of stress management, training this skill should be included in educational plans of university.

    Medical students' attitudes to mental illnesses and psychiatry may be reshaped during the psychiatric training, with important implications in their future practice of the profession. Therefore, the present study set out to explore the impact of the psychiatric clerkship in students' attitudes, while taking into consideration the site of their practical training. To this end, a total of 678 final-year medical students were recruited. Students completed a self-reported questionnaire entailing the Attitudes to Psychiatry scale, the Attitudes to Mental Illness scale and the Greek Social Distance scale before and after their placement. Findings indicate that the psychiatric clerkship had a positive effect in reducing stigma towards both psychiatry and mental illnesses, with the effect being more pronounced in the general hospital with respect to the former, while in the specialty hospital was more marked regarding the latter. A further exploration of the determinants of change revealed that the improvement discerned in the general hospital was only among those without professional experience of mental illnesses. Therefore, the psychiatric clerkship may exert a substantial influence on shaping favourable attitudes towards mental illnesses and psychiatry; however, other elements should also be taken into consideration, if the clerkship is to tackle stigma in healthcare.

The aim of this study was to compare attitudes of medical students of a Modern Curriculum at Hannover Medical School with those of the Traditional Curriculum before (pre and after (post a three-week clerkship in general practice. In parallel, we aimed to analyse several other variables such as age and gender, which could influence the attitudes.Methods: Prospective survey of n=287 5th-year students. Attitudes (dependent variable, Likert-scale items as well as socio-demographic characteristics (age, gender, rural/urban background, school leaving examination grades, former qualifications, experiences in general practice and career plans were requested. Attitudes were analysed separately according to these characteristics (e.g. career plans: general practitioner (GP/specialist, curriculum type and pre/post the clerkship in general practice. Bi- and multivariate statistical analysis was used including a factor analysis for grouping of the attitude items. Results: Most and remarkable differences of attitudes were seen after analysis according to gender. Women appreciated general practice more than men including a greater interest in chronic diseases, communication and psychosocial aspects. The clerkship (a total of n=165 students of the “post” survey could be matched contributed to positive attitudes of students of both gender, whereas the different curricula did not show such effects.Conclusions: Affective learning goals such as a positive attitude towards general practice have depended more on characteristics of students (gender and effects of a clerkship in general practice than on the curriculum type (modern, traditional so far. For the development of outcomes in medical education research as well as for the evolution of the Modern Curriculum such attitudes and other affective learning goals should be considered more frequently.

    Background Workplace harassment, a known risk factor for adult drinking, is understudied in college samples, but may help explain observed gender differences in drinking patterns. Objective We examine effects of sexual and generalized workplace harassment on changes in drinking behavior over the first semesters of college, and the extent to which these effects differ based on prematriculation drinking for men and women students. Method Data derive from two waves of a longitudinal study of eight Midwestern colleges and universities. Data were collected from 2080 employed students via a Web-based survey assessing sexual and generalized workplace harassment, stressful life events, drinking to intoxication, and binge drinking prior to freshman year (fall 2011) and approximately one year later (summer to fall 2012). At baseline, lifetime drinking status, frequency of alcohol consumption, and demographics were also assessed. Results Linear mixed modeling indicated that employed women students who were frequent drinkers prematriculation were at risk for high levels of drinking associated with workplace harassment, while men who were non-drinkers were most at risk of increasing problem drinking over time when exposed to workplace harassment. Conclusions Alcohol use prevention efforts directed towards employed students are needed both prior to and during college, to instruct students how to identify workplace harassment and cope in healthier ways with stressful workplace experiences. These efforts might be particularly useful in stemming problematic drinking among women who drink frequently prior to college, and preventing men who are non-drinkers upon college entry from initiating problematic drinking during subsequent enrollment years.

    McGill, Monica M.; Settle, Amber; Decker, Adrienne

    2013-06-01

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

  2. Science in the General Educational Development (GED) curriculum: Analyzing the science portion of GED programs and exploring adult students' attitudes toward science

    Science.gov (United States)

    Hariharan, Joya Reena

    The General Educational Development (GED) tests enable people to earn a high school equivalency diploma and help them to qualify for more jobs and opportunities. Apart from this main goal, GED courses aim at enabling adults to improve the condition of their lives and to cope with a changing society. In today's world, science and technology play an exceedingly important role in helping people better their lives and in promoting the national goals of informed citizenship. Despite the current efforts in the field of secondary science education directed towards scientific literacy and the concept of "Science for all Americans", the literature does not reflect any corresponding efforts in the field of adult education. Science education research appears to have neglected a population that could possibly benefit from it. The purpose of this study is to explore: the science component of GED programs, significant features of the science portion of GED curricula and GED science materials, and adult learners' attitudes toward various aspects of science. Data collection methods included interviews with GED students and instructors, content analysis of relevant materials, and classroom observations. Data indicate that the students in general feel that the science they learn should be relevant to their lives and have direct applications in everyday life. Student understanding of science and interest in it appears to be contingent to their perceiving it as relevant to their lives and to society. Findings indicate that the instructional approaches used in GED programs influence students' perceptions about the relevance of science. Students in sites that use strategies such as group discussions and field trips appear to be more aware of science in the world around them and more enthusiastic about increasing this awareness. However, the dominant strategy in most GED programs is individual reading. The educational strategies used in GED programs generally focus on developing reading

  4. General practitioner teachers’ job satisfaction and their medical students' wish to join the field – a correlational study

    Science.gov (United States)

    2014-01-01

    Background There will be increasing competition for young physicians worldwide as more and more physicians retire. While enthusiasm towards GP work is important for GP teachers as role models, satisfaction within the profession has declined. This study aims to determine if medical students’ desire to become GPs is related to the job satisfaction of their teaching GPs and explore the factors tied to this job satisfaction. Methods In this cross-sectional, correlational study, teaching GPs of the University of Bern and the fourth year medical students completing internships with them filled in separate questionnaires. Results Whether or not the GP teacher is perceived by a student to be satisfied with her/his job is correlated to that student’s satisfaction with the internship, which in turn, is correlated with student’s wish to be a GP after the internship. Results show which factors are most related to GP job satisfaction and the effect of working hours and their composition. Conclusions Medical students’ perception of their GP teachers’ job satisfaction positively affect their wish to become GPs, and their satisfaction with their internships adds to this. Enhancing the positive aspects of GP work, such as recognition, and improving negative ones, such as administrative duties, are necessary to attract medical students into the GP field. PMID:24655917

  9. The effects of duration of exposure to the REAPS model in developing students' general creativity and creative problem solving in science

    Science.gov (United States)

    Alhusaini, Abdulnasser Alashaal F.

    The Real Engagement in Active Problem Solving (REAPS) model was developed in 2004 by C. June Maker and colleagues as an intervention for gifted students to develop creative problem solving ability through the use of real-world problems. The primary purpose of this study was to examine the effects of the REAPS model on developing students' general creativity and creative problem solving in science with two durations as independent variables. The long duration of the REAPS model implementation lasted five academic quarters or approximately 10 months; the short duration lasted two quarters or approximately four months. The dependent variables were students' general creativity and creative problem solving in science. The second purpose of the study was to explore which aspects of creative problem solving (i.e., generating ideas, generating different types of ideas, generating original ideas, adding details to ideas, generating ideas with social impact, finding problems, generating and elaborating on solutions, and classifying elements) were most affected by the long duration of the intervention. The REAPS model in conjunction with Amabile's (1983; 1996) model of creative performance provided the theoretical framework for this study. The study was conducted using data from the Project of Differentiation for Diverse Learners in Regular Classrooms (i.e., the Australian Project) in which one public elementary school in the eastern region of Australia cooperated with the DISCOVER research team at the University of Arizona. All students in the school from first to sixth grade participated in the study. The total sample was 360 students, of which 115 were exposed to a long duration and 245 to a short duration of the REAPS model. The principal investigators used a quasi-experimental research design in which all students in the school received the treatment for different durations. Students in both groups completed pre- and posttests using the Test of Creative Thinking

    We describe a student-led project to image two seventh-magnitude stars on either side of the Sun during the solar eclipse of August 21, 2017. Both stars were within one solar radius of the Sun, and according to Einstein’s theory of General Relativity, their positions would have been shifted away from the Sun by 1 arcsec. We observed the eclipse from three different sites along the path of totality (Lexington, South Carolina; Indian Valley, Idaho; Madras, Oregon). All three sites were clear, but the brightness of the solar corona has complicated the analysis. We present preliminary results using our best images from the site in Idaho.

    between the OOA2 and WBOA factors and smoke levels indicates that these factors can be used to identify the influence of biomass burning on ambient aerosols. The effectiveness of using the ChemWiki instead of a traditional textbook was investigated during the spring quarter of 2014. Student performance was measured using common midterms, a final, and a pre/post content exams. We also employed surveys, the Colorado Learning Attitudes about Science Survey (CLASS) for Chemistry, and a weekly time-on-task survey to quantify students' attitudes and study habits. The effectiveness of the ChemWiki compared to a traditional textbook was examined using multiple linear regression analysis with a standard non-inferiority testing framework. Results show that the performance of students in the section who were assigned readings from the ChemWiki was non-inferior to the performance of students in the section who were assigned readings from the traditional textbook, indicating that the ChemWiki does not substantially differ from the standard textbook in terms of student learning outcomes. The results from the surveys also suggest that the two classes were similar in their beliefs about chemistry and overall average time spent studying. These results indicate that the ChemWiki is a viable cost-saving alternative to traditional textbooks. The impact of using active learning techniques in a large lecture general chemistry class was investigated by assessing student performance and attitudes during the fall 2014 and winter 2015 quarters. One instructor applied active learning strategies while the remaining instructors employed more traditional lecture styles. Student performance, learning, learning environments, and attitudes were measured using a standardized pre/post exams, common final exams, classroom observations, and the CLASS chemistry instrument in large lecture general chemistry courses. Classroom observation data showed that the active learning class was the most student centered

    2015-07-01

    Full Text Available Given that reforms involving how to deal with the past are extremely difficult, especially when the past involves memories of victimization, death, and destruction so widespread that a high percentage of the population is affected, the main purpose of this article is to describe how the general secondary education (GSE curriculum in East Timor –an ancient Portuguese colony– is organized in terms of principles and objectives, themes, and methodological guidelines that give priority to assisting students to minimize or manage problems associated with conflict. Subsequently, the current state of GSE is characterized, in terms of school organization and logistics, and mobilization of teachers and students in using the new curriculum. The empirical results show that curricular materials incorporate aspects that can contribute to understanding and minimizing or managing problems created by the conflict, as well as contributing to avoid new conflicts. Nevertheless, although textbooks incorporate these aspects and teachers and students express interest in use them, problems remain regarding their appropriate usage due to numerous factors such as: logistics; school organization and poor teacher skills, despite training given and continued focused investment.

    International Nuclear Information System (INIS)

    Woffinden, G.B.

    1981-01-01

    During the early part of the 1970s a need arose for suitable aids to assist lecturers in giving talks on radioactivity and radiation to employees and occasionally to science students in local schools and colleges. A kit capable of demonstrating the basic properties of alpha, beta and gamma radiation was assembled for these purposes. During the latter half of the decade a demand arose for talks to non-scientific groups of the general public on nuclear power and radiation and some of the items in the original demonstration kit were found to be appropriate for these talks. The items used, now constitute the Basic Demonstration Kit. Meanwhile, a few changes or additions were made to the original kit which is now known as the Comprehensive Demonstration Kit. (author)

    To evaluate the views of final year dental surgery students (BDS; G1) at Cardiff University and general dental practitioners (GDPs; G2) within the geographic area of Cardiff, Wales, on antibiotic prescribing for endodontic conditions, and investigate the potential differences between the two groups. A cross-sectional online questionnaire-based survey of 12 qualitative and quantitative questions was distributed to 76 final year BDS Cardiff University students and 55 dental practices within Cardiff, UK. Six questions recorded general information, and the remaining questions included a series of hypothetical clinical scenarios, where the participants were asked to state whether they would or would not prescribe antibiotics. The data were analysed using spss version 23 to produce descriptive statistics, contingency tables and to run chi-square (χ²) tests, Fisher's exact tests and relative risk calculations. The response rate was 60% (n = 79). All G1 participants were aware of the consequences of antibiotic overuse. Approximately 60% of responders were aware of guidelines for antibiotic use in endodontic therapies, and 83% would only use antibiotics for a limited selection of patients (e.g. patients with systemic complications). G1 responses to clinical scenarios indicated overall that they were comparable to the ideal answers except for acute apical abscess (64% believed that antibiotics were indicated). The majority of G2 were aware of the consequences of antibiotic overuse. Only 28% of G2 were aware of guidelines for antibiotic use in endodontic therapies. Overall responses revealed that antibiotics would be prescribed for: systemic complications (78%), acute apical abscess (72%) and symptomatic apical periodontitis (28%). The clinical scenarios revealed G1 were more likely to prescribe antibiotics compared to G2 for cases of necrotic pulp with symptomatic apical periodontitis without systemic complications (incorrect answer) and less likely to other clinical

    Generalized Polygons is the first book to cover, in a coherent manner, the theory of polygons from scratch. In particular, it fills elementary gaps in the literature and gives an up-to-date account of current research in this area, including most proofs, which are often unified and streamlined in comparison to the versions generally known. Generalized Polygons will be welcomed both by the student seeking an introduction to the subject as well as the researcher who will value the work as a reference. In particular, it will be of great value for specialists working in the field of generalized polygons (which are, incidentally, the rank 2 Tits-buildings) or in fields directly related to Tits-buildings, incidence geometry and finite geometry. The approach taken in the book is of geometric nature, but algebraic results are included and proven (in a geometric way!). A noteworthy feature is that the book unifies and generalizes notions, definitions and results that exist for quadrangles, hexagons, octagons - in the ...

    The Innovative Technology Demonstration (ITD) program at Tinker Air Force Base (TAFB), Oklahoma City, Oklahoma, will demonstrate the overall utility and effectiveness of innovative technologies for site characterization, monitoring, and remediation of selected contaminated test sites. The current demonstration test sites include a CERCLA site on the NPL list, located under a building (Building 3001) that houses a large active industrial complex used for rebuilding military aircraft, and a site beneath and surrounding an abandoned underground tank vault used for storage of jet fuels and solvents. The site under Building 3001 (the NW Test Site) is contaminated with TCE and Cr +6 ; the site with the fuel storage vault (the SW Tanks Site) is contaminated with fuels, BTEX and TCE. These sites and others have been identified for cleanup under the Air Force's Installation Restoration Program (IRP). This document describes the demonstrations that have been conducted or are planned for the TAFB

  16. Buried Waste Integrated Demonstration

    International Nuclear Information System (INIS)

    1994-03-01

    The Buried Waste Integrated Demonstration (BWID) supports the applied research, development, demonstration, and evaluation of a suite of advanced technologies that offer promising solutions to the problems associated with the remediation of buried waste. BWID addresses the difficult remediation problems associated with DOE complex-wide buried waste, particularly transuranic (TRU) contaminated buried waste. BWID has implemented a systems approach to the development and demonstration of technologies that will characterize, retrieve, treat, and dispose of DOE buried wastes. This approach encompasses the entire remediation process from characterization to post-monitoring. The development and demonstration of the technology is predicated on how a technology fits into the total remediation process. To address all of these technological issues, BWID has enlisted scientific expertise of individuals and groups from within the DOE Complex, as well as experts from universities and private industry. The BWID mission is to support development and demonstration of a suite of technologies that, when integrated with commercially-available technologies, forms a comprehensive, remediation system for the effective and efficient remediation of buried waste throughout the DOE Complex. BWID will evaluate and validate demonstrated technologies and transfer this information and equipment to private industry to support the Office of Environmental Restoration (ER), Office of Waste Management (WM), and Office of Facility Transition (FT) remediation planning and implementation activities

    Trongale, Nicholas A.

    2006-01-01

    The airspace operations demonstration (AOD) is intended to show that the Access 5 Step 1 functional requirements can be met. The demonstration will occur in two phases. The initial on-range phase will be carried out in restricted airspace to demonstrate the cooperative collision avoidance (CCA) functional requirements and to provide risk-reduction for the AOD by allowing the test team to rehearse some elements of the demonstration mission. The CCA system to be used in these flights is based on Automatic Dependent Surveillance-Broadcast (ADS-B) which is a commercially-available system by which airplanes constantly broadcast their current position and altitude to other aircraft and ground resources over a dedicated radio datalink. The final phase will occur in the national airspace (NAS) and will be the formal demonstration of the remainder of the proposed functional requirements. The general objectives of the AOD are as follows: (1) Demonstrate that the UAS can aviate in the NAS (2) Demonstrate that the UAS can navigate in the NAS (3) Demonstrate that the UAS can communicate with the NAS (4) Demonstrate that the UAS can perform selected collision avoidance functions in the NAS (5) Demonstrate that the UAS can evaluate and avoid weather conflicts in the NAS (6) Demonstrate that the UAS can provide adequate command and control in the NAS In addition to the stated objectives, there are a number of goals for the flight demonstration. The demo can be accomplished successfully without achieving these goals, but these goals are to be used as a guideline for preparing for the mission. The goals are: (1) Mission duration of at least 24 hours (2) Loiter over heavy traffic to evaluate the data block issue identified during the Access 5 Airspace Operations Simulations (3) Document the contingency management process and lessons learned (4) Document the coordination process for Ground Control Stations (GCS) handoff (5) Document lessons learned regarding the process of flying in

    Demonstration projects are often used in the building sector to provide a basis for using new processes and/or products. The climate change agenda implies that construction is not only required to deliver value for the customer, cost reductions and efficiency but also sustainable buildings....... This paper reports on an early demonstration project, the Building of a passive house dormitory in the Central Region of Denmark in 2006-2009. The project was supposed to deliver value, lean design, prefabrication, quality in sustainability, certification according to German standards for passive houses......, and micro combined heat and power using hydrogen. Using sociological and business economic theories of innovation, the paper discusses how early movers of innovation tend to obtain only partial success when demonstrating their products and often feel obstructed by minor details.

    1998-10-01

    In the framework of the IEA SHC Programme, a Task on building renovation was initiated, `Task 20, Solar Energy in Building Renovation`. In a part of the task, Subtask C `Design of Solar Renovation Projects`, different solar renovation demonstration projects were developed. The objective of Subtask C was to demonstrate the application of advanced solar renovation concepts on real buildings. This report documents 16 different solar renovation demonstration projects including the design processes of the projects. The projects include the renovation of houses, schools, laboratories, and factories. Several solar techniques were used: building integrated solar collectors, glazed balconies, ventilated solar walls, transparent insulation, second skin facades, daylight elements and photovoltaic systems. These techniques are used in several simple as well as more complex system designs. (au)

    1987-08-01

    A two-column biodenitrification (BDN) facility was constructed at the Feed Materials Production Center (FMPC) in 1985 and 1986 to test the feasibility of biological treatment for industrial nitrate-bearing waste water generated at FMPC. This demonstration facility comprises one-half of the proposed four-column production facility. A demonstration test was conducted over a four month period in 1987. The results indicate the proposed BDN production facility can process FMPC industrial wastewater in a continuous manner while maintaining an effluent that will consistently meet the proposed NPDES limits for combined nitrate nitrogen (NO 3 -N) and nitrite nitrogen (NO 2 -N). The proposed NPDES limits are 62 kg/day average and 124 kg/day maximum. These limits were proportioned to determine that the two-column demonstration facility should meet the limits of 31 kg/day average and 62 kg/day maximum

    2004-08-01

    A physical demonstration of distributed surveillance and tracking is described. The demonstration environment is an outdoor car park overlooked by a system of four rooftop cameras. The cameras extract moving objects from the scene, and these objects are tracked in a decentralized way, over a real communication network, using the information form of the standard Kalman filter. Each node therefore has timely access to the complete global picture and because there is no single point of failure in the system, it is robust. The demonstration system and its main components are described here, with an emphasis on some of the lessons we have learned as a result of applying a corpus of distributed data fusion theory and algorithms in practice. Initial results are presented and future plans to scale up the network are also outlined.

    The desirable characteristics of Canadian projects that demonstrate vehicle use in real-world operation and the appropriate mechanism to collect and disseminate the monitoring data were discussed in this presentation. The scope of the project was on passenger cars and light duty trucks operating in plug-in electric vehicle (PHEV) or battery electric vehicle modes. The presentation also discussed the funding, stakeholders involved, Canadian travel pattern analysis, regulatory framework, current and recent electric vehicle demonstration projects, and project guidelines. It was concluded that some demonstration project activities may have been duplicated as communication between the proponents was insufficient. It was recommended that data monitoring using automatic data logging with minimum reliance on logbooks and other user entry should be emphasized. figs.

    In the recent papers, the gravitational superconductivity is described. We introduce the concept of generalized superconductivity observing that any nongeodesic motion and, in particular, the motion in an electromagnetic field, can be transformed in a geodesic motion by a suitable choice of the connection. In the present paper, the gravitoelectromagnetic London equations have been obtained from the generalized Helmholtz vortex theorem using the generalized local equivalence principle. In this context, the gravitoelectromagnetic Meissner effect and, implicitly, the gravitoelectromagnetic levitation are given. (authors)

    Environmental Management Operations (EMO) is conducting an Innovative Technology Demonstration Program for Tinker Air Force Base (TAFB). Several innovative technologies are being demonstrated to address specific problems associated with remediating two contaminated test sites at the base. Cone penetrometer testing (CPT) is a form of testing that can rapidly characterize a site. This technology was selected to evaluate its applicability in the tight clay soils and consolidated sandstone sediments found at TAFB. Directionally drilled horizontal wells was selected as a method that may be effective in accessing contamination beneath Building 3001 without disrupting the mission of the building, and in enhancing the extraction of contamination both in ground water and in soil. A soil gas extraction (SGE) demonstration, also known as soil vapor extraction, will evaluate the effectiveness of SGE in remediating fuels and TCE contamination contained in the tight clay soil formations surrounding the abandoned underground fuel storage vault located at the SW Tanks Site. In situ sensors have recently received much acclaim as a technology that can be effective in remediating hazardous waste sites. Sensors can be useful for determining real-time, in situ contaminant concentrations during the remediation process for performance monitoring and in providing feedback for controlling the remediation process. Following the SGE demonstration, the SGE system and SW Tanks test site will be modified to demonstrate bioremediation as an effective means of degrading the remaining contaminants in situ. The bioremediation demonstration will evaluate a bioventing process in which the naturally occurring consortium of soil bacteria will be stimulated to aerobically degrade soil contaminants, including fuel and TCE, in situ

    Currently, several innovative technologies are being demonstrated at Tinker Air Force Base (TAFB) to address specific problems associated with remediating two contaminated test sites at the base. Cone penetrometer testing (CPT) is a form of testing that can rapidly characterize a site. This technology was selected to evaluate its applicability in the tight clay soils and consolidated sandstone sediments found at TAFB. Directionally drilled horizontal wells have been successfully installed at the US Department of Energy's (DOE) Savannah River Site to test new methods of in situ remediation of soils and ground water. This emerging technology was selected as a method that may be effective in accessing contamination beneath Building 3001 without disrupting the mission of the building, and in enhancing the extraction of contamination both in ground water and in soil. A soil gas extraction (SGE) demonstration, also known as soil vapor extraction, will evaluate the effectiveness of SGE in remediating fuels and TCE contamination contained in the tight clay soil formations surrounding the abandoned underground fuel storage vault located at the SW Tanks Site. In situ sensors have recently received much acclaim as a technology that can be effective in remediating hazardous waste sites. Sensors can be useful for determining real-time, in situ contaminant concentrations during the remediation process for performance monitoring and in providing feedback for controlling the remediation process. A demonstration of two in situ sensor systems capable of providing real-time data on contamination levels will be conducted and evaluated concurrently with the SGE demonstration activities. Following the SGE demonstration, the SGE system and SW Tanks test site will be modified to demonstrate bioremediation as an effective means of degrading the remaining contaminants in situ

    2015-10-13

    The Gigashot Optical Laser Demonstrator (GOLD) project has demonstrated a novel optical amplifier for high energy pulsed lasers operating at high repetition rates. The amplifier stores enough pump energy to support >10 J of laser output, and employs conduction cooling for thermal management to avoid the need for expensive and bulky high-pressure helium subsystems. A prototype amplifier was fabricated, pumped with diode light at 885 nm, and characterized. Experimental results show that the amplifier provides sufficient small-signal gain and sufficiently low wavefront and birefringence impairments to prove useful in laser systems, at repetition rates up to 60 Hz.

    The recently upgraded remote monitoring system at the Joyo Experimental Reactor uses a DCM-14 camera module and GEMINI software. The final data is compatible both with the IAEA-approved GARS review software and the ALIS software that was used for this demonstration. Features of the remote monitoring upgrade emphasized compatibility with IAEA practice. This presentation gives particular attention to the selection process for meeting network security considerations at the O'arai site. The Joyo system is different from the NNCA's ACPF system, in that it emphasizes use of IAEA standard camera technology and data acquisition and transmission software. In the demonstration itself, a temporary virtual private network (VPN) between the meeting room and the server at Sandia in Albuquerque allowed attendees to observe data stored from routine transmissions from the Joyo Fresh Fuel Storage to Sandia. Image files from a fuel movement earlier in the month showed Joyo workers and IAEA inspectors carrying out a transfer. (author)

    Low-level radioactive wastes (LLW) generated by nuclear utilities presently are shipped to commercial burial grounds for disposal. Substantially increasing shipping and disposal charges have sparked renewed industry interest in incineration and other advanced volume reduction techniques as potential cost-saving measures. Repeated inquiries from industry sources regarding LLW applicability of the Los Alamos controlled-air incineration (CAI) design led DOE to initiate this commercial demonstration program in FY-1980. The selected program approach to achieving CAI demonstration at a utility site is a DOE sponsored joint effort involving Los Alamos, a nuclear utility, and a liaison subcontractor. Required development tasks and responsibilities of the particpants are described. Target date for project completion is the end of FY-1985

    An attribute measurement system (AMS) measures a number of unclassified attributes of potentially classified material. By only displaying these unclassified results as red or green lights, the AMS protects potentially classified information while still generating confidence in the measurement result. The AVNG implementation that we describe is an AMS built by RFNC - VNIIEF in Sarov, Russia. To provide additional confidence, the AVNG was designed with two modes of operation. In the secure mode, potentially classified measurements can be made with only the simple red light/green light display. In the open mode, known unclassified material can be measured with complete display of the information collected from the radiation detectors. The AVNG demonstration, which occurred in Sarov, Russia in June 2009 for a joint US/Russian audience, included exercising both modes of AVNG operation using a number of multi-kg plutonium sources. In addition to describing the demonstration, we will show photographs and/or video taken of AVNG operation.

    Future energy production will be performed by advanced technologies that are more efficient, more environmentally friendly and less expensive than current technologies. Integrated gasification combined cycle (IGCC) power plants have been proposed as one of these systems. Utilising biofuels in future energy production will also be emphasised since this lowers substantially carbon dioxide emissions into the atmosphere due to the fact that biomass is a renewable form of energy. Combining advanced technology and biomass utilisation is for this reason something that should and will be encouraged. A. Ahlstrom Corporation of Finland and Sydkraft AB of Sweden have as one part of company strategies adopted this approach for the future. The companies have joined their resources in developing a biomass-based IGCC system with the gasification part based on pressurised circulating fluidized-bed technology. With this kind of technology electrical efficiency can be substantially increased compared to conventional power plants. As a first concrete step, a decision has been made to build a demonstration plant. This plant, located in Vaernamo, Sweden, has already been built and is now in commissioning and demonstration stage. The system comprises a fuel drying plant, a pressurised CFB gasifier with gas cooling and cleaning, a gas turbine, a waste heat recovery unit and a steam turbine. The plant is the first in the world where the integration of a pressurised gasifier with a gas turbine will be realised utilising a low calorific gas produced from biomass. The capacity of the Vaernamo plant is 6 MW of electricity and 9 MW of district heating. Technology development is in progress for design of plants of sizes from 20 to 120 MWe. The paper describes the Bioflow IGCC system, the Vaernamo demonstration plant and experiences from the commissioning and demonstration stages. (orig.)

    2008-01-01

    In cooperation with the Canadian Space Agency, the Northern Centre for Advanced Technology, Inc., the Carnegie-Mellon University, JPL, and NEPTEC, NASA has undertaken the In-Situ Resource Utilization (ISRU) project called RESOLVE. This project is a ground demonstration of a system that would be sent to explore permanently shadowed polar lunar craters, drill into the regolith, determine what volatiles are present, and quantify them in addition to recovering oxygen by hydrogen reduction. The Lunar Prospector has determined these craters contain enhanced hydrogen concentrations averaging about 0.1%. If the hydrogen is in the form of water, the water concentration would be around 1%, which would translate into billions of tons of water on the Moon, a tremendous resource. The Lunar Water Resource Demonstration (LWRD) is a part of RESOLVE designed to capture lunar water and hydrogen and quantify them as a backup to gas chromatography analysis. This presentation will briefly review the design of LWRD and some of the results of testing the subsystem. RESOLVE is to be integrated with the Scarab rover from CMIJ and the whole system demonstrated on Mauna Kea on Hawaii in November 2008. The implications of lunar water for Mars exploration are two-fold: 1) RESOLVE and LWRD could be used in a similar fashion on Mars to locate and quantify water resources, and 2) electrolysis of lunar water could provide large amounts of liquid oxygen in LEO, leading to lower costs for travel to Mars, in addition to being very useful at lunar outposts.

    Within the Belgian R and D programme on geological disposal, demonstration experiments have become increasingly important. In this contribution to the scientific report 2001, an overview is given of SCK-CEN's activities and achievements in the field of large-scale demonstration experiments. In 2001, main emphasis was on the PRACLAY project, which is a large-scale experiment to demonstrate the construction and the operation of a gallery for the disposal of HLW in a clay formation. The PRACLAY experiment will contribute to enhance understanding of water flow and mass transport in dense clay-based materials as well as to improve the design of the reference disposal concept. In the context of PRACLAY, a surface experiment (OPHELIE) has been developed to prepare and to complement PRACLAY-related experimental work in the HADES Underground Research Laboratory. In 2001, efforts were focussed on the operation of the OPHELIE mock-up. SCK-CEN also contributed to the SELFRAC roject which studies the self-healing of fractures in a clay formation

    2011-01-01

    Modern approaches for information technology based blended education utilize a variety of novel instructional, computational and network resources. Such attempts employ technology to deliver integrated, dynamically linked, interactive content and multifaceted learning environments, which may facilitate student comprehension and information retention. In this manuscript, we describe one such innovative effort of using technological tools for improving student motivation and learning of the theory, practice and usability of the Central Limit Theorem (CLT) in probability and statistics courses. Our approach is based on harnessing the computational libraries developed by the Statistics Online Computational Resource (SOCR) to design a new interactive Java applet and a corresponding demonstration activity that illustrate the meaning and the power of the CLT. The CLT applet and activity have clear common goals; to provide graphical representation of the CLT, to improve student intuition, and to empirically validate and establish the limits of the CLT. The SOCR CLT activity consists of four experiments that demonstrate the assumptions, meaning and implications of the CLT and ties these to specific hands-on simulations. We include a number of examples illustrating the theory and applications of the CLT. Both the SOCR CLT applet and activity are freely available online to the community to test, validate and extend (Applet: http://www.socr.ucla.edu/htmls/SOCR_Experiments.html and Activity: http://wiki.stat.ucla.edu/socr/index.php/SOCR_EduMaterials_Activities_GeneralCentralLimitTheorem).

Reflective tasks can stimulate students to recognise their own learning needs. Assessment of portfolios using a rating scale relating to intended learning outcomes offers high content validity. This study evaluated a reflective portfolio used during a final-year attachment in general practice (family medicine). Students were asked to evaluate the portfolio (which used significant event analysis as a basis for reflection) as a learning tool. The validity and reliability of the portfolio as an assessment tool were also measured. 81 final-year medical students completed reflective significant event analyses as part of a portfolio created during a three-week attachment (clerkship) in general practice (family medicine). As well as two reflective significant event analyses each portfolio contained an audit and a health needs assessment. Portfolios were marked three times; by the student's GP teacher, the course organiser and by another teacher in the university department of general practice. Inter-rater reliability between pairs of markers was calculated. A questionnaire enabled the students' experience of portfolio learning to be determined. Benefits to learning from reflective learning were limited. Students said that they thought more about the patients they wrote up in significant event analyses but information as to the nature and effect of this was not forthcoming. Moderate inter-rater reliability (Spearman's Rho .65) was found between pairs of departmental raters dealing with larger numbers (20-60) of portfolios. Inter-rater reliability of marking involving GP tutors who only marked 1-3 portfolios was very low. Students rated highly their mentoring relationship with their GP teacher but found the portfolio tasks time-consuming. The inter-rater reliability observed in this study should

  2. Generalized polygons

    Maldeghem, Hendrik

    1998-01-01

    This book is intended to be an introduction to the fascinating theory ofgeneralized polygons for both the graduate student and the specialized researcher in the field. It gathers together a lot of basic properties (some of which are usually referred to in research papers as belonging to folklore) and very recent and sometimes deep results. I have chosen a fairly strict geometrical approach, which requires some knowledge of basic projective geometry. Yet, it enables one to prove some typically group-theoretical results such as the determination of the automorphism groups of certain Moufang polygons. As such, some basic group-theoretical knowledge is required of the reader. The notion of a generalized polygon is a relatively recent one. But it is one of the most important concepts in incidence geometry. Generalized polygons are the building bricks of Tits buildings. They are the prototypes and precursors of more general geometries such as partial geometries, partial quadrangles, semi-partial ge­ ometries, near...

    A model reactor for HITEX successfully demonstrated the concept of high-temperature isotopic exchange in a closed loop simulating the conditions for fusion fuel cleanup. The catalyst of platinum on alumina pellets provided a surface area large enough to operate the reactor at 400 degrees celsius with flow rates up to 2 L/min. A 15-L tank containing a mixture of 4% CD 4 in H 2 was depleted in deuterium within 75 minutes down to 100 ppm HD above the natural concentration of HD in the make-up hydrogen stream. The application to tritium removal from tritiated impurities in a hydrogen stream will work as well or better

    The Visual Electricity Demonstrator (VED) is a linear diode array that serves as a dynamic alternative to an ammeter. A string of 48 red light-emitting diodes (LEDs) blink one after another to create the illusion of a moving current. Having the current represented visually builds an intuitive and qualitative understanding about what is happening in a circuit. In this article, I describe several activities for this device and explain how using this technology in the classroom can enhance the understanding and appreciation of physics.

    BACKGROUND: Exploration class missions will present significant new challenges and hazards to the health of the astronauts. Regardless of the intended destination, beyond low Earth orbit a greater degree of crew autonomy will be required to diagnose medical conditions, develop treatment plans, and implement procedures due to limited communications with ground-based personnel. SCOPE: The Exploration Medical System Demonstration (EMSD) project will act as a test bed on the International Space Station (ISS) to demonstrate to crew and ground personnel that an end-to-end medical system can assist clinician and non-clinician crew members in optimizing medical care delivery and data management during an exploration mission. Challenges facing exploration mission medical care include limited resources, inability to evacuate to Earth during many mission phases, and potential rendering of medical care by non-clinicians. This system demonstrates the integration of medical devices and informatics tools for managing evidence and decision making and can be designed to assist crewmembers in nominal, non-emergent situations and in emergent situations when they may be suffering from performance decrements due to environmental, physiological or other factors. PROJECT OBJECTIVES: The objectives of the EMSD project are to: a. Reduce or eliminate the time required of an on-orbit crew and ground personnel to access, transfer, and manipulate medical data. b. Demonstrate that the on-orbit crew has the ability to access medical data/information via an intuitive and crew-friendly solution to aid in the treatment of a medical condition. c. Develop a common data management framework that can be ubiquitously used to automate repetitive data collection, management, and communications tasks for all activities pertaining to crew health and life sciences. d. Ensure crew access to medical data during periods of restricted ground communication. e. Develop a common data management framework that

    Low-level radioactive wastes (LLW) generated by nuclear utilities presently are shipped to commercial burial grounds for disposal. Increasing transportation and disposal costs have caused industry to consider incineration as a cost-effective means of volume reduction of combustible LLW. Repeated inquiries from the nuclear industry regarding the applicability of the Los Alamos controlled air incineration (CAI) design led the DOE to initiate a commercial demonstration program in FY-1980. Development studies and results in support of this program involving ion exchange resin incineration and fission/activation product distributions within the Los Alamos CAI are described

    The National Rural Electric Cooperative Association (NRECA) organized the NRECA-U.S. Department of Energy (DOE) Smart Grid Demonstration Project (DE-OE0000222) to install and study a broad range of advanced smart grid technologies in a demonstration that spanned 23 electric cooperatives in 12 states. More than 205,444 pieces of electronic equipment and more than 100,000 minor items (bracket, labels, mounting hardware, fiber optic cable, etc.) were installed to upgrade and enhance the efficiency, reliability, and resiliency of the power networks at the participating co-ops. The objective of this project was to build a path for other electric utilities, and particularly electrical cooperatives, to adopt emerging smart grid technology when it can improve utility operations, thus advancing the co-ops’ familiarity and comfort with such technology. Specifically, the project executed multiple subprojects employing a range of emerging smart grid technologies to test their cost-effectiveness and, where the technology demonstrated value, provided case studies that will enable other electric utilities—particularly electric cooperatives— to use these technologies. NRECA structured the project according to the following three areas: Demonstration of smart grid technology; Advancement of standards to enable the interoperability of components; and Improvement of grid cyber security. We termed these three areas Technology Deployment Study, Interoperability, and Cyber Security. Although the deployment of technology and studying the demonstration projects at coops accounted for the largest portion of the project budget by far, we see our accomplishments in each of the areas as critical to advancing the smart grid. All project deliverables have been published. Technology Deployment Study: The deliverable was a set of 11 single-topic technical reports in areas related to the listed technologies. Each of these reports has already been submitted to DOE, distributed to co-ops, and

    The objective of the project was to design and manufacture a device to demonstrate a new technology developed by NASA's Electrostatics and Surface Physics Laboratory. The technology itself is a system which uses magnetic principles to remove regolith dust from its surface. This project was to create an enclosure that will be used to demonstrate the effectiveness of the invention to The Office of the Chief Technologist. ONE of the most important challenges of space exploration is actually caused by something very small and seemingly insignificant. Dust in space, most notably on the moon and Mars, has caused many unforeseen issues. Dirt and dust on Earth, while a nuisance, can be easily cleaned and kept at bay. However, there is considerably less weathering and erosion in space. As a result, the microscopic particles are extremely rough and abrasive. They are also electrostatically charged, so they cling to everything they make contact with. This was first noted to be a major problem during the Apollo missions. Dust would stick to the spacesuits, and could not be wiped off as predicted. Dust was brought back into the spacecraft, and was even inhaled by astronauts. This is a major health hazard. Atmospheric storms and other events can also cause dust to coat surfaces of spacecraft. This can cause abrasive damage to the craft. The coating can also reduce the effectiveness of thermal insulation and solar panels.' A group of engineers at Kennedy Space Center's Electrostatics and Surface Physics Laboratory have developed a new technology, called the Electrodynamic Dust Shield, to help alleviate these problems. It is based off of the electric curtain concept developed at NASA in 1967. "The EDS is an active dust mitigation technology that uses traveling electric fields to transport electrostatically charged dust particles along surfaces. To generate the traveling electric fields, the EDS consists of a multilayer dielectric coating with an embedded thin electrode grid

    In an effort to promote clean energy projects and aid in the commercialization of new fuel cell technologies the Long Island Power Authority (LIPA) initiated a Fuel Cell Demonstration Program in 1999 with six month deployments of Proton Exchange Membrane (PEM) non-commercial Beta model systems at partnering sites throughout Long Island. These projects facilitated significant developments in the technology, providing operating experience that allowed the manufacturer to produce fuel cells that were half the size of the Beta units and suitable for outdoor installations. In 2001, LIPA embarked on a large-scale effort to identify and develop measures that could improve the reliability and performance of future fuel cell technologies for electric utility applications and the concept to establish a fuel cell farm (Farm) of 75 units was developed. By the end of October of 2001, 75 Lorax 2.0 fuel cells had been installed at the West Babylon substation on Long Island, making it the first fuel cell demonstration of its kind and size anywhere in the world at the time. Designed to help LIPA study the feasibility of using fuel cells to operate in parallel with LIPA's electric grid system, the Farm operated 120 fuel cells over its lifetime of over 3 years including 3 generations of Plug Power fuel cells (Lorax 2.0, Lorax 3.0, Lorax 4.5). Of these 120 fuel cells, 20 Lorax 3.0 units operated under this Award from June 2002 to September 2004. In parallel with the operation of the Farm, LIPA recruited government and commercial/industrial customers to demonstrate fuel cells as on-site distributed generation. From December 2002 to February 2005, 17 fuel cells were tested and monitored at various customer sites throughout Long Island. The 37 fuel cells operated under this Award produced a total of 712,635 kWh. As fuel cell technology became more mature, performance improvements included a 1% increase in system efficiency. Including equipment, design, fuel, maintenance

  14. Direct Demonstration of the Greenhouse Effect

    Consider these three "theories:" climate change, evolution, and gravity. Why are two of them hotly debated by non-scientists, but not gravity? In part, the answer is that climate change and evolution are more complex processes and not readily observable over short time scales to most people. In contrast, the "theory of gravity" is tested every day by billions of people world-wide and is therefore not challenged. While there are numerous "demonstrations" of the greenhouse effect available online, unfortunately, many of them are based on poor understanding of the physical principles involved. For this reason, we sought to develop simple and direct experiments that would demonstrate aspects of the greenhouse effect that would be suitable for museums, K-12, and/or college classrooms. We will describe two experiments. In the first, we use a simple plexiglass tube, approximately 12 cm long, with IR transparent windows. The tube is first filled with dry nitrogen and exposed to an IR heat lamp. Following this, the tube is filled with pure, dry CO2. Both tubes warm up, but the tube filled with CO2 ends up about 0.7 degrees C warmer. It is useful to compare this 12 cm column of CO2 to the column in the earth's atmosphere, which is equivalent to approximately 2.7 meters of pure CO2. This demonstration would be suitable for museum exhibits to demonstrate the physical basis of CO2 heating in the atmosphere. In the second experiment, we use FTIR spectroscopy to quantify the CO2 content of ambient air and indoor/classroom air. For this experiment, we use a commercial standard of 350 ppm CO2 to calibrate the absorption features. Once the CO2 content of ambient air is found, it is useful for students to compare their observed value to background data (e.g. NOAA site in Hawaii) and/or the "Keeling Curve". This leads into a discussion on causes for local variations and the long-term trends. This experiment is currently used in our general chemistry class but could be used in many

    As a satellite to the MARS (Mirror Advanced Reactor Study) a smaller, near-term device has been scoped, called the FPD (Fusion Power Demonstration). Envisioned as the next logical step toward a power reactor, it would advance the mirror fusion program beyond MFTF-B and provide an intermediate step toward commercial fusion power. Breakeven net electric power capability would be the goal such that no net utility power would be required to sustain the operation. A phased implementation is envisioned, with a deuterium checkout first to verify the plasma systems before significant neutron activation has occurred. Major tritium-related facilities would be installed with the second phase to produce sufficient fusion power to supply the recirculating power to maintain the neutral beams, ECRH, magnets and other auxiliary equipment

    A major element of the shutdown of the US liquid metal reactor development program is managing the sodium-bonded spent metallic fuel from the Experimental Breeder Reactor-II to meet US environmental laws. Argonne National Laboratory has refurbished and equipped an existing hot cell facility for treating the spent fuel by a high-temperature electrochemical process commonly called pyroprocessing. Four products will be produced for storage and disposal. Two high-level waste forms will be produced and qualified for disposal of the fission and activation products. Uranium and transuranium alloys will be produced for storage pending a decision by the US Department of Energy on the fate of its plutonium and enriched uranium. Together these activities will demonstrate a unique electrochemical treatment technology for spent nuclear fuel. This technology potentially has significant economic and technical advantages over either conventional reprocessing or direct disposal as a high-level waste option

    Prototypes of the plant components, meeting the specifications set by the process and built by industrial firms in collaboration with the supervisor and the C.E.A., are subjected to trial runs on the UF 6 test bench of the Pierrelatte testing zone. These items of equipment (diffuser, compressor, exchanger) are placed in an industrial operation context very similar to that of an enrichment plant. Their performance is measured within a broad region around the working point and their reliability observed over periods up to several tens of thousands of hours. Between 1969 and 1973 six industrial demonstration test benches have been built, marking the stages in the technical preparation of the 1973 file on the basis of which the decision of building was taken by Eurodif [fr

    1985-07-01

    This is the third in the series of reports covering the Fusion Power Demonstration (FPD) design study. This volume considers the FPD-III configuration that incorporates an octopole end plug. As compared with the quadrupole end-plugged designs of FPD-I and FPD-II, this octopole configuration reduces the number of end cell magnets and shortens the minimum ignition length of the central cell. The end-cell plasma length is also reduced, which in turn reduces the size and cost of the end cell magnets and shielding. As a contiuation in the series of documents covering the FPD, this report does not stand alone as a design description of FPD-III. Design details of FPD-III subsystems that do not differ significantly from those of the FPD-II configuration are not duplicated in this report

    The TPA (torus plasma for amature) is a small race-trac type device made by the technical service division to demonstrate basic properties of plasma such as electron temperature, conductivity, effect of helical field for toroidal drift, and shape of plasma in mirror and cusp magnetic field in linear section. The plasmas are produced by RF discharge (-500W) and/or DC discharge (-30 mA) within glass discharge tube. Where major radius is 50 cm, length of linear section is 50 cm, toroidal magnetic field is 200 gauss. The device has been designed to be compact with only 100 V power source (-3.2 KW for the case without helical field) and to be full automatic sequence of operation. (author)
