Francisco, Joseph S.; Nicoll, Gayle; Trautmann, Marcella

1998-02-01

In addition to the traditional lecture format, three other teaching strategies (class discussions, concept maps, and cooperative learning) were incorporated into a freshman level general chemistry course. Student perceptions of their involvement in each of the teaching methods, as well as their perceptions of the utility of each method were used to assess the effectiveness of the integration of the teaching strategies as received by the students. Results suggest that each strategy serves a unique purpose for the students and increased student involvement in the course. These results indicate that the multiple teaching strategies were well received by the students and that all teaching strategies are necessary for students to get the most out of the course.

The motivation to teach as a registrar in general practice.

The General Medical Council (GMC) states that teaching should be an integral part of the doctor's role and the Royal College of General Practitioners (RCGP) have incorporated teaching outcomes into the GP training curriculum. However, there are suggestions that the teaching role of a GP trainee declines as they move from hospital posts to the registrar community year. Using doctors in training as near-peer tutors offers multiple advantages. Trainees themselves benefit as teaching others is a strong driver of the tutor's own learning. In addition there are also practical incentives to mobilising this under-utilised pool of primary care clinical teachers given the continuing shift of focusing medical education in the community. This study forms part of a larger body of work exploring the attitudes and perceived learning needs of GP registrars with regards to developing a teaching role. A primary area of investigation was trainees' motivation to teach. This paper describes our attempts to establish: a) how strongly motivated are GP registrars to take on teaching roles? b) in consequence how strongly motivated are they to learn more about teaching? c) what are the factors which affect motivation to teach? Three themes emerged from the data. First, teaching was felt to be of low priority in comparison to competing clinical learning needs. Secondly, the clinical dominance to both formative and summative assessment during training further compounded this situation. Thirdly, registrars identified a number of practical barriers and incentives that influenced their teaching engagement. This included potential negative views from trainers as to their trainee's ability and requirement to be involved with teaching activities.
By understanding and addressing these issues, it is hoped that GP trainees' engagement with teaching activities can be better engendered with subsequent benefits for both the trainee and those they teach.

2011-04-01

As the first step of an instrument development, teaching challenges that occur when students with autism spectrum disorders are educated in general physical education were elicited using Goldfried and D'Zurilla's (1969) behavioral-analytic model. Data were collected from a convenience sample of 43 certified physical educators (29 women and 14 men) using a demographic questionnaire and an elicitation questionnaire. Participants listed 225 teaching challenges, 46% related to cooperative, 31% to competitive, and 24% to individualistic learning situations. Teaching challenges were categorized into nine themes: inattentive and hyperactive behaviors, social impairment, emotional regulation difficulties, difficulties understanding and performing tasks, narrow focus and inflexible adherence to routines and structure, isolation by classmates, negative effects on classmates' learning, and need for support.

Teaching complex verbal operants to children with autism and establishing generalization using the peak curriculum.

The present study evaluated the feasibility of the PEAK Relational Training System's Generalization Module (Dixon, 2014b) to teach and establish generalization of autoclitic mands, distorted tacts, and creative path finding in three children diagnosed with autism spectrum disorder. Using a multiple-baseline design across behaviors, each participant was provided with differential reinforcement and a least-to-most prompting hierarchy for correct responses to a subset of stimuli, and responses to other similar stimulus sets were probed for emergent generalization. Following training, each participant successfully acquired the directly trained behaviors and demonstrated generalization to the nonreinforced test exemplars. These data support the utility of Skinner's (1957) analysis to teach complex forms of verbal operants, and suggest that a manualized curriculum such as PEAK may have utility for promoting skill development and generalization for front line staff and caregivers of children with autism. © 2017 Society for the Experimental Analysis of Behavior.

Teaching Energy to a General Audience

NASA Astrophysics Data System (ADS)

Baski, Alison; Hunnicutt, Sally

2010-02-01

A new, interdisciplinary course entitled ``Energy!'' has been developed by faculty in the physics and chemistry departments to meet the university's science and technology general education requirement. This course now enrolls over 400 students each semester in a single lecture where faculty from both departments co-teach throughout the term. Topics include the fundamentals of energy, fossil fuels, global climate change, nuclear energy, and renewable energy sources. The students represent an impressive range of majors (science, engineering, business, humanities, etc.) and comprise freshmen to seniors. To effectively teach this diverse audience and increase classroom engagement, in-class ``clickers'' are used with guided questions to teach concepts, which are then explicitly reinforced with online LON-CAPAfootnotetextFree open-source distributed learning content management and assessment system (www.lon-capa.org) homework. This online system enables immediate feedback in a structured manner, where students can practice randomized versions of problems for homework, quizzes, and exams. The course is already in high demand after only two semesters, in part because it is particularly relevant to students given the challenging energy and climate issues facing the nation and world. )

Teaching Einsteinian physics at schools: part 1, models and analogies for relativity

NASA Astrophysics Data System (ADS)

Kaur, Tejinder; Blair, David; Moschilla, John; Stannard, Warren; Zadnik, Marjan

2017-11-01

The Einstein-First project aims to change the paradigm of school science teaching through the introduction of modern Einsteinian concepts of space and time, gravity and quanta at an early age. These concepts are rarely taught to school students despite their central importance to modern science and technology. The key to implementing the Einstein-First curriculum is the development of appropriate models and analogies. This paper is the first part of a three-paper series. It presents the conceptual foundation of our approach, based on simple physical models and analogies, followed by a detailed description of the models and analogies used to teach concepts of general and special relativity. Two accompanying papers address the teaching of quantum physics (Part 2) and research outcomes (Part 3).

2014-04-01

To determine if the financial costs of teaching GP registrars differs between rural and urban practices. Cost-benefit analysis of teaching activities in private GP for GP vocational training. Data were obtained from a survey of general practitioners in South Australia and Western Australia. General practitioners and practices teaching in association with the Adelaide to Outback General Practice Training Program or the Western Australian General Practice Training. Net financial effect per week per practice. At all the training levels, rural practices experienced a financial loss for teaching GP registrars, while urban practices made a small financial gain. The differences in net benefit between rural and urban teaching practices was significant at the GPT2/PRRT2 (-$515 per week 95% CI -$1578, -$266) and GPT3/PRRT3 training levels (-$396 per week, 95% CI (-$2568, -$175). The variables contributing greatest to the difference were the higher infrastructure costs for a rural practice and higher income to the practice from the GP registrars in urban practices. There were significant differences in the financial costs and benefits for a teaching rural practice compared with an urban teaching practice. With infrastructure costs which include accommodation, being a key contributor to the difference found, it might be time to review the level of incentives paid to practices in this area. If not addressed, this cost difference might be a disincentive for rural practices to participate in teaching. © 2014 National Rural Health Alliance Inc.

To examine vertical integration of teaching and clinical training in general practice and describe practical examples being undertaken by Australian general practice regional training providers (RTPs). A qualitative study of all RTPs in Australia, mid 2010. All 17 RTPs in Australia responded. Eleven had developed some vertical integration initiatives. Several encouraged registrars to teach junior doctors and medical students, others encouraged general practitioner supervisors to run multilevel educational sessions, a few coordinated placements, linkages and support across their region. Three RTPs provided case studies of vertical integration. Many RTPs in Australia use vertical integration of teaching in their training programs. RTPs with close associations with universities and rural clinical schools seem to be leading these initiatives.

Patients make a crucial contribution to undergraduate medical education. Although a national resource is available for patients participating in research, none is as yet available for education. This study aimed to explore what information patients would like about participation in general practice based undergraduate medical education, and how they would like to obtain this information. Two focus groups were conducted in London-based practices involved in both undergraduate and postgraduate teaching. Patients both with and without teaching experience were recruited using leaflets, posters, and patient participation groups. An open-ended topic guide explored three areas: perceived barriers that participants anticipated or had experienced; patient roles in medical education; and what help would support participation. Focus groups were audiorecorded, transcribed, and analysed thematically. Patients suggested ways of professionalising the teaching process. These were: making information available to patients about confidentiality, iterative consent, and normalising teaching in the practice. Patients highlighted the importance of relationships, making information available about their GPs' involvement in teaching, and initiating student-patient interactions. Participants emphasised educational principles to maximise exchange of information, including active participation of students, patient identification of student learner needs, and exchange of feedback. This study will inform development of patient information resources to support their participation in teaching and access to information both before and during general practice based teaching encounters. © British Journal of General Practice 2017.

Effective teaching for general surgery residents requires that faculty members with colorectal expertise actively engage in the education process and fully understand the current context for residency training. In this article, we review important national developments with respect to graduate medical education that impact resident supervision, curriculum implementation, resident assessment, and program evaluation. We argue that establishing a culture of respect and professionalism in today's teaching environment is one of the most important legacies that surgical educators can leave for the coming generation. Faculty role modeling and the process of socializing residents is highlighted. We review the American College of Surgeons' Code of Professional Conduct, summarize some of the current strategies for teaching and assessing professionalism, and reflect on principles of motivation that apply to resident training both for the trainee and the trainer.

Teaching children generalized imitation skills: a case report.

Brown, Freddy Jackson; Peace, Natalie; Parsons, Rachel

2009-03-01

Generalized imitation plays an important role in the acquisition of new skills, in particular language and communication. In this case report a multiple exemplar training procedure, with an errorless learning phase, was used to teach Ben, a 13-year-old child with severe intellectual disabilities, to imitate behaviours modelled by an adult instructor. After exposure to seven multiple exemplars, Ben learned to imitate novel actions to criterion (i.e. generalized imitation). These skills were maintained at 90 percent at 6 week and 18 week follow-up. In line with earlier research, this article provides some further support for the finding that multiple exemplar training can facilitate the reliable emergence of generalized imitation skills. Topographically similar behaviours during the learning phase can be difficult to discriminate and hence can slow the learning process. Future research could explore how generalized imitation supports the development of basic communication and activity skills.

Clinician educators face numerous obstacles to their joint mission of facilitating high-quality learning while also delivering patient-centered care. Such challenges necessitate increased attention to the work of exemplary clinician educators, their respective teaching approaches, and the experiences of their learners. To describe techniques and behaviors utilized by clinician educators to facilitate excellent teaching during inpatient general medicine rounds. An exploratory qualitative study of inpatient teaching conducted from 2014 to 2015. Inpatient general medicine wards in 11 US hospitals, including university-affiliated hospitals and Veterans Affairs medical centers. Participants included 12 exemplary clinician educators, 57 of their current learners, and 26 of their former learners. In-depth, semi-structured interviews of exemplary clinician educators, focus group discussions with their current and former learners, and direct observations of clinical teaching during inpatient rounds. Interview data, focus group data, and observational field notes were coded and categorized into broad, overlapping themes. Each theme elucidated a series of actions, behaviors, and approaches that exemplary clinician educators consistently demonstrated during inpatient rounds: (1) they fostered positive relationships with all team members by building rapport, which in turn created a safe learning environment; (2) they facilitated patient-centered teaching points, modeled excellent clinical exam and communication techniques, and treated patients as partners in their care; and (3) they engaged in coaching and collaboration through facilitation of discussion, effective questioning strategies, and differentiation of learning among team members with varied experience levels. This study identified consistent techniques and behaviors of excellent teaching during inpatient general medicine rounds. © 2017 Society of Hospital Medicine

Individualised training to improve teaching competence of general practitioner trainers: a randomised controlled trial.

PubMed

Schol, Sandrina; Goedhuys, Jo; Notten, Ton; Betz, Wim

2005-10-01

In Flanders an important part of training to become a general practitioner (GP) is undertaken within a general practice. This requires a GP trainer to know how to facilitate learning processes. This paper reports a study focused on the research question: Does short but individualised training of GP trainers contribute to their teaching competence? A total of 47 GP trainers were randomly divided into 2 groups of a pretest/post-test control group design. After a multiple-station teaching assessment test (MSTAT), the experimental group received a short but individualised training to improve teaching competence while the control group were given no specific programme regarding teaching competence. One year later, all participants were invited to sit the post-test. In all, 61 GP trainers participated in the pretest and 51 in the post-test; 44 GP trainers participated in both tests. Despite the large attrition, the internal validity of the experiment was preserved. Beginners gained a median score of 2.04 (on a scale of 0-5) on the first MSTAT. In the post-test, the experimental group (median = 3.12) scored significantly better on the entire test (Mann-Whitney U = 166.5, P < 0.05) compared with the control group (median = 2.84). However, the GP trainers in the control group also appeared to have made progress. General practitioners who start as GP trainers have insufficient teaching competence to guarantee good coaching of students. A personal programme leads to progress in teaching competence; however, it would seem that more time and support are necessary to allow GP trainers to gain full teaching competence. The fact that the control group made progress as well suggests that the test had an important learning effect.

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 (P<0.05) associated with alumni currently undertaking in-practice clinical teaching and supervision were: Australian medical graduation (odds ratio (OR) for international graduates 0.36; 95% CI 0.14-0.92), working in a regional or remote area (OR 2.75; 95% CI 1.24-6.11) and currently undertaking nursing home visits, home visits or after-hours work (OR 2.01; CI 1.02-3.94). Conclusions Rural-urban and country-of-graduation differences in the engagement of early career GPs in practice-based apprenticeship-like teaching or training should inform strategies to maintain workforce training capacity. What is known about the topic? Projected changes in the demand for and supply of clinical teaching and supervision within Australian general

An approach to teaching general chemistry II that highlights the interdisciplinary nature of science.

PubMed

Sumter, Takita Felder; Owens, Patrick M

2011-01-01

The need for a revised curriculum within the life sciences has been well-established. One strategy to improve student preparation in the life sciences is to redesign introductory courses like biology, chemistry, and physics so that they better reflect their disciplinary interdependence. We describe a medically relevant, context-based approach to teaching second semester general chemistry that demonstrates the interdisciplinary nature of biology and chemistry. Our innovative method provides a model in which disciplinary barriers are diminished early in the undergraduate science curriculum. The course is divided into three principle educational modules: 1) Fundamentals of General Chemistry, 2) Medical Approaches to Inflammation, and 3) Neuroscience as a connector of chemistry, biology, and psychology. We accurately anticipated that this modified approach to teaching general chemistry would enhance student interest in chemistry and bridge the perceived gaps between biology and chemistry. The course serves as a template for context-based, interdisciplinary teaching that lays the foundation needed to train 21st century scientists. Copyright © 2010 Wiley Periodicals, Inc.

The teaching researcher: faculty attitudes towards the teaching and research roles

NASA Astrophysics Data System (ADS)

Alpay, E.; Verschoor, R.

2014-07-01

Results from a survey on faculty attitudes towards the teaching and research roles are presented. Attention is given to: (i) the perceived value of teaching (and teaching achievements) relative to research, (ii) approaches for research and teaching integration, (iii) the satisfaction gained from typical work tasks, and (iv) the importance of various work-life factors. Factors such as academic freedom, an intellectual work environment, flexible work hours, inspirational colleagues, and work diversity are found to be highly valued. Support from peers and colleagues is also seen as a key in learning to manage the different academic roles. A relatively low value is attributed to teaching achievements. Likewise, there is often little utilisation of teaching opportunities to support research work (other than senior-year research projects). Female faculty were found to give marginally a higher importance to teaching recognition and collaborative teaching opportunities. Based on the findings, general recommendations for supporting the teaching researcher are presented.

Teaching skills related to self-employment to adults with developmental disabilities: an analog analysis.

2013-08-01

Employment opportunities for people with developmental disabilities (DD) have improved in the last several decades. There is increasing focus on helping people with DD sample more diverse employment options, including running their own businesses. The present study (1) evaluated the effects of a well-established behavioral teaching procedure on the acquisition of a sample of three broad classes of skills related to self-employment (worker, supervisor, and clerical work) in young adults with DD within an analog recycling business, and (2) investigated the extension of that treatment to the natural environment while working in isolation or in peer pairs. Results suggest that the teaching procedure was effective in teaching three broad classes of skills related to many self-employment possibilities, the skills generalized to the natural environment, and peer pairs supported each other to complete tasks with a high degree of accuracy required to run a recycling business. This study represents an initial demonstration that adults with DD can learn skills required to run their own business. Copyright © 2013 Elsevier Ltd. All rights reserved.

Method Patients both with and without teaching experience were recruited using leaflets, posters, and patient participation groups. An open-ended topic guide explored three areas: perceived barriers that participants anticipated or had experienced; patient roles in medical education; and what help would support participation. Focus groups were audiorecorded, transcribed, and analysed thematically. Results Patients suggested ways of professionalising the teaching process. These were: making information available to patients about confidentiality, iterative consent, and normalising teaching in the practice. Patients highlighted the importance of relationships, making information available about their GPs’ involvement in teaching, and initiating student–patient interactions. Participants emphasised educational principles to maximise exchange of information, including active participation of students, patient identification of student learner needs, and exchange of feedback. Conclusion This study will inform development of patient information resources to support their participation in teaching and access to information both before and during general practice based teaching encounters.

The need for a revised curriculum within the life sciences has been well-established. One strategy to improve student preparation in the life sciences is to redesign introductory courses like biology, chemistry, and physics so that they better reflect their disciplinary interdependence. We describe a medically relevant, context-based approach to teaching second semester general chemistry that demonstrates the interdisciplinary nature of biology and chemistry. Our innovative method provides a model in which disciplinary barriers are diminished early in the undergraduate science curriculum. The course is divided into three principle educational modules: 1) Fundamentals of General Chemistry, 2) Medical Approaches to Inflammation, and 3) Neuroscience as a connector of chemistry, biology, and psychology. We accurately anticipated that this modified approach to teaching general chemistry would enhance student interest in chemistry and bridge the perceived gaps between biology and chemistry. The course serves as a template for context-based, interdisciplinary teaching that lays the foundation needed to train 21st century scientists. PMID:21445902

Academic institutions of general practice at German medical faculties have grown during the past years. This leads to an increase in the need of qualified young researchers and teachers in general practice (GP). Little is known about the interest in research and teaching skills and their training among general practice trainees and young GPs. This cross-sectional survey among GP trainees and young GPs examined 1. if there is an interest in the training in research and teaching skills during post-graduate GP training, 2. which fostering and hindering factors have an effect on this interest and 3. which roles are attributed to academic institutions of general practice. A web-based cross-sectional study was performed among members of "Verbundweiterbildung plus" , a network of GP trainees, as well as "Junge Allgemeinmedizin Deutschland", the German network of young GPs. Descriptive analysis was conducted. 148 GP trainees and young GPs participated in the study, 76% (n=109) of them were GP trainees. There was interest in a position in research and teaching during post-graduate GP training among 55% (n=78). Factors associated with the interest in a position in research and teaching during post-graduate GP training were (MV 5-point Likert scale ± SD): compatibility of clinical work and research/teaching and of family and career (4.4±0.8; 4.7±0.6 respectively). The roles of academic institutions of general practice were attributed to training of medical students (4.6±0.6), post-graduate GP training (4.5±0.7) and research (4.5±0.7). GP trainees assessed the importance of training in research and teaching skills during post-graduate GP training and of the compatibility of family and career differently from young GPs (3.7±1.0 vs. 4.1±0.8 p=0.027; 4.8±0.5 vs. 4.3±0.9, p=0.016). Those interested in a position in research and teaching during post-graduate GP training showed a stronger interest in specific training in research skills (3.7±1.1 vs. 2.8±1.1, p<0.001), a

Background In Australia, training for general practice (GP) occurs within private practices and their involvement in teaching can have significant financial costs. At the same time there are growing demands for clinical places for all disciplines and for GP there is concern that there are insufficient teaching practices to meet the demand at the medical student, prevocational and vocational training levels. One option to address this may be to change how teaching occurs in the practice. A question that arises in posing such an option is whether different models of teaching change the costs for a teaching practice. The aim of this study is to determine the net financial outcome of teaching models in private GP. Methods Modelling the financial implications for a range of teaching options using a costing framework developed from a survey of teaching practices in South Australia. Each option was compared with the traditional model of teaching where one GP supervisor is singularly responsible for one learner. The main outcome measure was net financial outcome per week. Decisions on the model cost parameters were made by the study's Steering Group which comprised of experienced GP supervisors. Four teaching models are presented. Model 1 investigates the gains from teaching multiple same level learners, Models 2 and 3, the benefits of vertically integrated teaching using different permutations, and Model 4 the concept of a GP teacher who undertakes all the teaching. Results There was a significant increase in net benefits of Aus$547 per week (95% confidence intervals $459, $668) to the practice when a GP taught two same level learners (Model 1) and when a senior registrar participated in teaching a prevocational doctor (Model 3, Aus$263, 95% confidence intervals $80, $570). For Model 2, a practice could significantly reduce the loss if a registrar was involved in vertically integrated teaching which included the training of a medical student (Aus$551, 95% confidence

The new-found popularity of generalism as a political force has emphasized the need to clarify the essential philosophy that underpins its practice, teaching, and research. Drawing on the example of Sir James Mackenzie, the author seeks to clarify certain essential issues that need to be emphasized if we are to promote and develop general practice as a distinct academic discipline. Dissatisfaction, uncertainty about our role, and continuing contact with real people seems to be essential to continuing creativity. PMID:9474833

Relations Between Student Procrastination and Teaching Styles: Autonomy-Supportive and Controlling.

2018-01-01

Procrastination is a complex problem that can be defined as delaying an intended course of action (despite anticipating adverse consequences). Even when some students have equivalent motivation and skill levels, they tend to procrastinate more frequently than others. Approaches that analyze whether contextual influences may prevent or promote dysregulation processes associated with procrastination are scarce. According to Self-Determination Theory, contextual influences can facilitate self-regulated motivation (e.g., autonomous pursuit of interests or personal goals), if teaching style is autonomy-supportive and guarantees the satisfaction of students' basic psychological needs for perceived competence, autonomy, and relatedness. Contrariwise, school context can also impede the development of autonomous motivation if teachers frustrate the satisfaction of their students' psychological needs by recurring to controlling teaching behaviors, such as controlling use of rewards, negative conditional regard, excessive personal control, or intimidation. The goal of the present study was to assess the relations between controlling and autonomy-supportive teaching behaviors, psychological needs satisfaction (of the needs for competence, autonomy, and relatedness), and four distinct measures of procrastination: general procrastination, decisional procrastination, procrastination linked to task avoidance, and pure procrastination. Data based on public university undergraduate students ( N = 672) shows that controlling teaching behaviors are associated negatively with psychological needs satisfaction and positively with procrastination. Contrariwise, autonomy-supportive teaching behaviors are positively associated with psychological needs satisfaction and negatively with procrastination. The data obtained is useful for suggesting new lines of research to study the link between contextual influences and the prevention of academic procrastination in view of Self

Deflection of light to second order: A tool for illustrating principles of general relativity

NASA Astrophysics Data System (ADS)

Bodenner, Jeremiah; Will, Clifford M.

2003-08-01

We calculate the deflection of light by a spherically symmetric body in general relativity, to second order in the quantity GM/dc2, where M is the mass of the body and d is a measure of the distance of closest approach of the ray. Using three different coordinate systems for the Schwarzschild metric we show that the answers for the deflection, while the same at order GM/dc2, differ at order (GM/dc2)2. We demonstrate that all three expressions are really the same by expressing them in terms of measurable, coordinate-independent quantities. These results provide concrete illustrations of the meaning of coordinates and coordinate invariance, which may be useful in teaching general relativity.

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

NASA Astrophysics Data System (ADS)

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

2011-04-01

action of a relativistic point particle as being `in proper time parametrisation', while the actual calculations of course impose the proper time condition only in the equation of motion after the action has been varied. Two presentational conventions surprised me. First, the speed of light is throughout kept explicitly as c: might advanced undergraduates appreciate being trusted with geometric units, reinstating c by dimensional analysis when desired? Second, in Minkowski space field theory, the overall coefficient in the action is chosen so that the time derivative term is negative, with the consequence that the Hamiltonian is negative (as explicitly noted in an exercise) and the definition of the energy-momentum tensor must include a minus sign to achieve the usual choice T00 > 0. This convention eliminates some minus signs in the computations with the spin two field: does this computational saving outweigh the adjustment awaiting those who continue with the topic at graduate level? Overall, Franklin's book is an excellent addition to the literature, and its readability and explicitness will be appreciated by the target audience. Should I be teaching an introductory undergraduate class in general relativity in the near future, I would seriously consider this book for the main class text.

The present contribution is an example of a reconstruction of thedebate concerning the foundations of General Relativity on the basis of cultural and educational criteria.In particular, the debate will be presented as guided by the concept of space, and by the different perspectives from whichsuch a concept can be viewed. It will be pointed out that the various ways of looking at space give powerfulcriteria not only to create an order among the interpretations, but also to exploit the educational and culturalvalue of the debate.

A hundred years after its birth, general relativity has become a highly successful theory in the sese that it has passed many experimental and observational tests and finds widespread application to diverse set of cosmic phenomena. It remains an accurate research field as more tests are deployed, epitomized by the exciting prospect of detecting gravitational radiation directly. General realtivity is the essential foundation of modern cosmology and underlies our detailed description of the black holes and neutron stars that are ultimately responsible for the most powerful and dramatic cosmic sources. The interface with physics on both the largest and the smallest scales continues to be very fertile. In this talk I will attempt to highlight some key steps along the way to general relativity today.

Why and how do general practitioners teach? An exploration of the motivations and experiences of rural Australian general practitioner supervisors.

Ingham, Gerard; Fry, Jennifer; O'Meara, Peter; Tourle, Vianne

2015-10-29

In medical education, a learner-centred approach is recommended. There is also a trend towards workplace-based learning outside of the hospital setting. In Australia, this has resulted in an increased need for General Practitioner (GP) supervisors who are receptive to using adult learning principles in their teaching. Little is known about what motivates Australian GP supervisors and how they currently teach. A qualitative study involving semi-structured interviews with 20 rural GP supervisors who work within one Regional Training Provider region in Australia explored their reasons for being a supervisor and how they performed their role. Data was analysed using a thematic analysis approach. GP supervisors identified both personal and professional benefits in being a supervisor, as well as some benefits for their practice. Supervision fulfilled a perceived broader responsibility to the profession and community, though they felt it had little impact on rural retention of doctors. While financial issues did not provide significant motivation to teach, the increasing financial inequity compared with providing direct patient care might impact negatively on the decision to be or to remain a supervisor in the future. The principal challenge for supervisors was finding time for teaching. Despite this, there was little evidence of supervisors adopting strategies to reduce teaching load. Teaching methods were reported in the majority to be case-based with styles extending from didactic to coach/facilitator. The two-way collegiate relationship with a registrar was valued, with supervisors taking an interest in the registrars beyond their development as a clinician. Supervisors report positively on their teaching and mentoring roles. Recruitment strategies that highlight the personal and professional benefits that supervision offers are needed. Practices need assistance to adopt models of supervision and teaching that will help supervisors productively manage the increasing

We used a graduated guidance procedure to teach 4 boys with autism to follow photographic activity schedules to increase on-task and on-schedule behavior. The multiple baseline across participants design included baseline, teaching, maintenance, resequencing of photographs, and generalization to novel photographs phases. The results indicated that photographic activity schedules (albums depicting after-school activities) produced sustained engagement, and skills generalized to a new sequence of photographs and to new photographs. The acquisition of schedule-following skills enabled these children with severe developmental disabilities to display lengthy response chains, independently change activities, and change activities in different group home settings in the absence of immediate supervision and prompts from others.

2016-01-01

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

A series of 55 laparoscopic colectomies performed by 1 trainee were evaluated. Next, the learning curves for high anterior resection performed by the trainee (n=20) were compared with those of a self-trained surgeon (n=19). Cumulative sum analysis and multivariate regression analyses showed that 38 completed cases were needed to reduce the operative time. In high anterior resection, the mean operative times were significantly shorter after the seventh average for the tutored surgeon compared with that for the self-trained surgeon. In cumulative sum charting, the curve reached a plateau by the seventh case for the tutored surgeon, but continued to increase for the self-trained surgeon. Mentor tutoring effectively teaches laparoscopic colorectal surgical skills in a general hospital setting.

As surgery becomes incorporated into global health programs, it will be critical for clinicians to take into account already existing surgical care systems within low-income countries. To inform future efforts to expand the local system and systems in comparable regions of the developing world, we aimed to describe current patterns of surgical care at a major urban teaching hospital in Mozambique. We performed a retrospective review of all general surgery patients treated between August 2012 and August 2013 at the Hospital Central Maputo in Maputo, Mozambique. We reviewed emergency and elective surgical logbooks, inpatient discharge records, and death records to report case volume, disease etiology, and mortality. There were 1598 operations (910 emergency and 688 elective) and 2606 patient discharges during our study period. The most common emergent surgeries were for nontrauma laparotomy (22%) followed by all trauma procedures (18%), whereas the most common elective surgery was hernia repair (31%). The majority of lower extremity amputations were above knee (69%). The most common diagnostic categories for inpatients were infectious (31%), trauma (18%), hernia (12%), neoplasm (10%), and appendicitis (5%). The mortality rate was 5.6% (146 deaths), approximately half of which were related to sepsis. Our data demonstrate the general surgery caseload of a large, academic, urban training and referral center in Mozambique. We describe resource limitations that impact operative capacity, trauma care, and management of amputations and cancer. These findings highlight challenges that are applicable to a broad range of global surgery efforts. Copyright © 2015 Elsevier Inc. All rights reserved.

Teaching and learning the geological knowledge as a part of the science education general field

NASA Astrophysics Data System (ADS)

Aguirre-Pérez, Constancio

2010-05-01

Since the early 50s of last century the Teaching of Science has undergone a process of continuous development, (Gutiérrez, 1987; Aliberas, Gutierrez and Izquierdo, 1989) to become a scientific discipline largely accepted as such by many different universities worldwide. Besides, the proliferation of publications, magazines, conferences, symposia, meetings, and so on, proves this assertion. In these publications and meetings the Teaching of Science (or Science Education in more general terms) is addressed as a new field of research, teaching and educational innovation focused on the processes of teaching and learning of the experimental sciences (all of them: Physics, Chemistry, Biology and Geology). The study of this discipline is undertaken from different pedagogical, epistemological, psychological and sociological approaches. From this general perspective we can say that over the last two decades each of the sciences has developed specific characteristics so that, today, we could speak about specific didactics for each one of them. In the case of Geology (or Geoscience) Teaching there have been significant contributions from the following fields of research: the students' prior ideas (constructivist approach), the history of geology (as a subject-specific field) and from epistemology (Pedrinaci, E. 2000). The body of geoscience knowledge has an internal logic (as happens with the other science subjects) that allows us to organize the contents to teach, selecting, arranging and establishing proper relations between them. Still geology has a central, transverse, inter-and transdisciplinary character for its relationship with the other sciences. This character makes it appear as one of the disciplines with a huge potential to combine different methodologies of teaching and learning and different learning models already tested in the research field of Physics, Chemistry or Biology Education. Moreover, the most recent term coined for it "geosciences or earth and

Amador, S

1994-01-01

By judiciously selecting topics and reading materials, one can teach a full semester course on medical physics appropriate for college students not majoring in the natural sciences. This interdisciplinary field offers an opportunity to teach a great deal of basic physics at the freshman level in the context of explaining modern medical technologies such as ultrasound imaging, laser surgery, and positron emission tomography. This article describes one such course which combines lectures, outside visitors, varied readings, and laboratories to convey a select subset of physical principles and quantitative problem-solving skills. These resources are also valuable for enriching the standard freshman physics sequence for premedical students. PMID:8075355

Climate Change Concepts and POGIL: Using climate change to teach general chemistry

NASA Astrophysics Data System (ADS)

King, D. B.; Lewis, J. E.; Anderson, K.; Latch, D.; Sutheimer, S.; Webster, G.; Middlecamp, C.; Moog, R.

2013-12-01

Climate change is a topic that can be used to engage students in a variety of courses and disciplines. Through an NSF-funded project, we have written a set of in-class POGIL (Process Oriented Guided Inquiry Learning) activities that use climate change topics to teach general chemistry concepts. POGIL is a pedagogical approach that uses group activities to teach content and process skills. In these group activities an initial model and a series of critical thinking questions are used to guide students through the introduction to or application of course content. Students complete the activities on their own, with the faculty member as a facilitator of learning, rather than a provider of information. Through assigned group roles and intentionally designed activity structure, process skills, such as teamwork, communication, and information processing, are developed during completion of the activity. While POGIL activities were initially developed for chemistry courses, this approach has now been used to create materials for use in other fields, such as biology, math, engineering and computer science. An additional component of this project is the incorporation of questions that relate to socio-scientific issues, e.g., the economic and social effects of climate change policies. The goal is for students to use evidence-based arguments in situations where opinion-based arguments are common. Key components (i.e., models and the corresponding critical thinking questions) of one activity will be presented. We will also report preliminary feedback based on initial classroom testing of several of the activities.

Teaching Special Relativity Without Calculus

NASA Astrophysics Data System (ADS)

Ruby, Lawrence

2009-04-01

I 2007 many AAPT members received a booklet that is the first chapter of a physics textbook available on a CD. This book espouses the new educational philosophy of teaching special relativity as the first item in the topic of mechanics. Traditionally, special relativity is part of one or more modern physics chapters at the end of the text,2 and very often this material is never utilized due to time constraints. From a logical standpoint, special relativity is important in satellite communications and in cosmology, as well as in modern physics applications such as atomic theory and high-energy physics. The purpose of this paper is to show that the new philosophy can be carried out in a noncalculus physics course, by demonstrating that all of the principal results of special relativity theory can be obtained by simple algebra. To accomplish this, we shall propose alternate derivations for two results that are usually obtained with calculus. Textbooks2 typically obtain the equations for time dilation and for length contraction from simple considerations based on Einstein's second postulate.3 We shall start from this point.

Spinning fluids in general relativity

NASA Technical Reports Server (NTRS)

Ray, J. R.; Smalley, L. L.

1982-01-01

General relativity field equations are employed to examine a continuous medium with internal spin. A variational principle formerly applied in the special relativity case is extended to the general relativity case, using a tetrad to express the spin density and the four-velocity of the fluid. An energy-momentum tensor is subsequently defined for a spinning fluid. The equations of motion of the fluid are suggested to be useful in analytical studies of galaxies, for anisotropic Bianchi universes, and for turbulent eddies.

A new model of special relativity and the relationship between the time warps of general and special relativity

NASA Astrophysics Data System (ADS)

Stannard, Warren B.

2018-05-01

Einstein’s two theories of relativity were introduced over 100 years ago. High school science students are seldom exposed to these revolutionary ideas as they are often perceived to be too difficult conceptually and mathematically. This paper brings together the two theories of relativity in a way that is logical and consistent and enables the teaching of relativity as a single subject. This paper introduces new models and analogies which are suitable for the teaching of Einstein’s relativity at a high school level, exposing students to our best understanding of time, space, matter and energy.

Attitudes of health science students towards teaching practices, examinations, and other related issues.

PubMed

Shephard, R J; Ashley, M J

1979-03-01

A brief multiple choice questionnaire explored the attitudes of students enrolled in several health science faculties (medicine, pharmacy, nursing, and physical and health education). A substantial proportion indicated a wish for more challenging lectures. On the other hand, the majority of students devoted less than one hour of personal study per week to required 'courses', interest in health-related 'courses' being particularly weak. Small textbooks with minimal references were desired, and relatively little use was made of free lecture handouts. Financial constraints had little influence on personal study, but affected textbook purchase. The demand for 'handouts' would have been reduced by a charge. Frequent term examinations as a stimulus to learning were favoured by all groups, as were full or challenging presentations by instructors. Team teaching, although favoured generally, was not equally appealing to all groups.

Do quality indicators for general practice teaching practices predict good outcomes for students?

PubMed

Bartlett, Maggie; Potts, Jessica; McKinley, Bob

2016-07-01

Keele medical students spend 113 days in general practices over our five-year programme. We collect practice data thought to indicate good quality teaching. We explored the relationships between these data and two outcomes for students; Objective Structured Clinical Examination (OSCE) scores and feedback regarding the placements. Though both are surrogate markers of good teaching, they are widely used. We collated practice and outcome data for one academic year. Two separate statistical analyses were carried out: (1) to determine how much of the variation seen in the OSCE scores was due to the effect of the practice and how much to the individual student. (2) to identify practice characteristics with a relationship to student feedback scores. (1) OSCE performance: 268 students in 90 practices: six quality indicators independently influenced the OSCE score, though without linear relationships and not to statistical significance. (2) Student satisfaction: 144 students in 69 practices: student feedback scores are not influenced by practice characteristics. The relationships between the quality indicators we collect for practices and outcomes for students are not clear. It may be that neither the quality indicators nor the outcome measures are reliable enough to inform decisions about practices' suitability for teaching.

General relativity in upper secondary school: Design and evaluation of an online learning environment using the model of educational reconstruction

Kersting, Magdalena; Henriksen, Ellen Karoline; Bøe, Maria Vetleseter; Angell, Carl

2018-06-01

Because of its abstract nature, Albert Einstein's theory of general relativity is rarely present in school physics curricula. Although the educational community has started to investigate ways of bringing general relativity to classrooms, field-tested educational material is rare. Employing the model of educational reconstruction, we present a collaborative online learning environment that was introduced to final year students (18-19 years old) in six Norwegian upper secondary physics classrooms. Design-based research methods guided the development of the learning resources, which were based on a sociocultural view of learning and a historical-philosophical approach to teaching general relativity. To characterize students' learning from and interaction with the learning environment we analyzed focus group interviews and students' oral and written responses to assigned problems and discussion tasks. Our findings show how design choices on different levels can support or hinder understanding of general relativity, leading to the formulation of design principles that help to foster qualitative understanding and encourage collaborative learning. The results indicate that upper secondary students can obtain a qualitative understanding of general relativity when provided with appropriately designed learning resources and sufficient scaffolding of learning through interaction with teacher and peers.

Video-assisted feedback in general practice internships using German general practitioner's guidelines

2012-01-01

Introduction: The planned modification of the Medical Licenses Act in Germany will strengthen the specialty of general practice. Therefore, medical students should get to know the daily routine of general practitioners during their academic studies. At least 10% of students should get the possibility to spend one quarter of the internship, in the last year of their academic studies, in a practice of family medicine. The demonstrated teaching method aims at giving feedback to the student based on video recordings of patient consultations (student-patient) with the help of a checklist. Video-feedback is already successful used in medical teaching in Germany and abroad. This feasibility study aims at assessing the practicability of video-assisted feedback as a teaching method during internship in general practice. Teaching method: First of all, the general practice chooses a guideline as the learning objective. Secondly, a subsequent patient – student – consultation is recorded on video. Afterwards, a video-assisted formative feedback is given by the physician. A checklist with learning objectives (communication, medical examination, a structured case report according to the guideline) is used to structure the feedback content. Feasibility: The feasibility was assessed by a semi structured interview in order to gain insight into barriers and challenges for future implementation. The teaching method was performed in one general practice. Afterwards the teaching physician and the trainee intern were interviewed. The following four main categories were identified: feasibility, performance, implementation in daily routine, challenges of the teaching concept. The results of the feasibility study show general practicability of this approach. Installing a video camera in one examination room may solve technical problems. The trainee intern mentioned theoretical and practical benefits using the guideline. The teaching physician noted the challenge to reflect on his daily

This article discusses the crucial role of teaching and learning communication skills for general practitioners, based on the theory of experiential and self-directed learning. It also outlines the proposed ways and methods to teach these communication skills in this project. The patient-doctor interview or what is known as office visit in some countries and consultation in others is the cornerstone of the entire General Practice (GP) or Family Medicine. It is from this process and outcome that the reputation is gained or destroyed. The analysis of the consultation is complicated and varied but is most usefully employed to assess effecacy in terms of achieving the means that are mutually desired by patients and their carers.

Quality Teaching in Science: an Emergent Conceptual Framework

NASA Astrophysics Data System (ADS)

Jordens, J. Zoe; Zepke, Nick

2017-09-01

Achieving quality in higher education is a complex task involving the interrelationship of many factors. The influence of the teacher is well established and has led to some general principles of good teaching. However, less is known about the extent that specific disciplines influence quality teaching. The purposes of the paper are to investigate how quality teaching is perceived in the sciences and from these perceptions to develop for discussion a framework for teaching practice in the sciences. A New Zealand study explored the views of national teaching excellence award winners in science on quality teaching in undergraduate science. To capture all possible views from this expert panel, a dissensus-recognising Delphi method was used together with sensitising concepts based on complexity and wickedity. The emergent conceptual framework for quality teaching in undergraduate science highlighted areas of consensus and areas where there were a variety of views. About the purposes of science and its knowledge base, there was relative consensus, but there was more variable support for values underpinning science teaching. This highlighted the complex nature of quality teaching in science. The findings suggest that, in addition to general and discipline-specific influences, individual teacher values contribute to an understanding of quality in undergraduate science teaching.

Energy and Uncertainty in General Relativity

NASA Astrophysics Data System (ADS)

Cooperstock, F. I.; Dupre, M. J.

2018-03-01

The issue of energy and its potential localizability in general relativity has challenged physicists for more than a century. Many non-invariant measures were proposed over the years but an invariant measure was never found. We discovered the invariant localized energy measure by expanding the domain of investigation from space to spacetime. We note from relativity that the finiteness of the velocity of propagation of interactions necessarily induces indefiniteness in measurements. This is because the elements of actual physical systems being measured as well as their detectors are characterized by entire four-velocity fields, which necessarily leads to information from a measured system being processed by the detector in a spread of time. General relativity adds additional indefiniteness because of the variation in proper time between elements. The uncertainty is encapsulated in a generalized uncertainty principle, in parallel with that of Heisenberg, which incorporates the localized contribution of gravity to energy. This naturally leads to a generalized uncertainty principle for momentum as well. These generalized forms and the gravitational contribution to localized energy would be expected to be of particular importance in the regimes of ultra-strong gravitational fields. We contrast our invariant spacetime energy measure with the standard 3-space energy measure which is familiar from special relativity, appreciating why general relativity demands a measure in spacetime as opposed to 3-space. We illustrate the misconceptions by certain authors of our approach.

High school health-education teachers' perceptions and practices related to teaching HIV prevention.

2012-11-01

HIV/AIDS is one of the leading causes of illness and death in the United States with individuals between the ages of 13 and 19 years being especially vulnerable for infection. The purpose of this study was to examine the attitudes, perceptions, and instructional practices of high school health teachers toward teaching HIV prevention. A total of 800 surveys were sent to a national random sample of high school health teachers and 50% responded. There was almost complete agreement (99%) among respondents that HIV prevention instruction is needed. The factors that emerged as significantly influencing the attitudes and perceptions of high school health teachers about teaching HIV prevention were related to teacher preparation, training, and years of experience teaching health education. A state mandate requiring HIV prevention instruction was significantly associated with higher teacher efficacy expectations and more perceived benefits, but did not have a significant influence in relation to practices in the classroom. Characteristics of high school health teachers that were significantly related to attitudes, perceptions, and instructional practices included the instructor's age, sex, and race/ethnicity. High school health teachers who reported the least experience teaching health education had the least supportive attitudes, perceived the most barriers, and had the lowest efficacy and outcome expectations related to teaching about HIV prevention. Whereas these findings support the importance of teacher preparation and training, they also suggest that more recent college graduates may not be fully prepared to provide effective instruction in HIV prevention. © 2012, American School Health Association.

2013-01-01

In a large (250 registrants) general education lecture course, neuroscience principles were taught by two professors as co-instructors, starting with simple brain anatomy, chemistry, and function, proceeding to basic brain circuits of pleasure and pain, and progressing with fellow expert professors covering relevant philosophical, artistic, marketing, and anthropological issues. With this as a base, the course wove between fields of high relevance to psychology and neuroscience, such as food addiction and preferences, drug seeking and craving, analgesic pain-inhibitory systems activated by opiates and stress, neuroeconomics, unconscious decision-making, empathy, and modern neuroscientific techniques (functional magnetic resonance imaging and event-related potentials) presented by the co-instructors and other Psychology professors. With no formal assigned textbook, all lectures were PowerPoint-based, containing links to supplemental public-domain material. PowerPoints were available on Blackboard several days before the lecture. All lectures were also video-recorded and posted that evening. The course had a Facebook page for after-class conversation and one of the co-instructors communicated directly with students on Twitter in real time during lecture to provide momentary clarification and comment. In addition to graduate student Teaching Assistants (TAs), to allow for small group discussion, ten undergraduate students who performed well in a previous class were selected to serve as discussion leaders. The Discussion Leaders met four times at strategic points over the semester with groups of 20–25 current students, and received one credit of Independent Study, thus creating a course within a course. The course grade was based on weighted scores from two multiple-choice exams and a five-page writing assignment in which each student reviewed three unique, but brief original peer-review research articles (one page each) combined with expository writing on the first

The course grade was based on weighted scores from two multiple-choice exams and a five-page writing assignment in which each student reviewed three unique, but brief original peer-review research articles (one page each) combined with expository writing on the first

Teaching Physics for Conceptual Understanding Exemplified for Einstein's Special Relativity

NASA Astrophysics Data System (ADS)

Undreiu, Lucian M.

2006-12-01

In most liberal arts colleges the prerequisites for College Physics, Introductory or Calculus based, are strictly related to Mathematics. As a state of fact, the majorities of the students perceive Physics as a conglomerate of mathematical equations, a collection of facts to be memorized and they regard Physics as one of the most difficult subjects. A change of this attitude towards Physics, and Science in general, is intrinsically connected with the promotion of conceptual understanding and stimulation of critical thinking. In such an environment, the educators are facilitators, rather than the source of knowledge. One good way of doing this is to challenge the students to think about what they see around them and to connect physics with the real world. Motivation occurs when students realize that what was learned is interesting and relevant. Visual teaching aids such as educational videos or computer simulations, as well as computer-assisted experiments, can greatly enhance the effectiveness of a science lecture or laboratory. Difficult topics can be discussed through animated analogies. Special Relativity is recognized as a challenging topic and is probably one of the most misunderstood theories of Physics. While understanding Special Relativity requires a detachment from ordinary perception and every day life notions, animated analogies can prove to be very successful in making difficult topics accessible.

Testing general relativity on accelerators

DOE PAGES

Kalaydzhyan, Tigran

2015-09-07

Within the general theory of relativity, the curvature of spacetime is related to the energy and momentum of the present matter and radiation. One of the more specific predictions of general relativity is the deflection of light and particle trajectories in the gravitational field of massive objects. Bending angles for electromagnetic waves and light in particular were measured with a high precision. However, the effect of gravity on relativistic massive particles was never studied experimentally. Here we propose and analyze experiments devoted to that purpose. We demonstrate a high sensitivity of the laser Compton scattering at high energy accelerators tomore » the effects of gravity. The main observable – maximal energy of the scattered photons – would experience a significant shift in the ambient gravitational field even for otherwise negligible violation of the equivalence principle. In conclusion, we confirm predictions of general relativity for ultrarelativistic electrons of energy of tens of GeV at a current level of resolution and expect our work to be a starting point of further high-precision studies on current and future accelerators, such as PETRA, European XFEL and ILC.« less

Chemistry Graduate Teaching Assistants' Experiences in Academic Laboratories and Development of a Teaching Self-image

NASA Astrophysics Data System (ADS)

Gatlin, Todd Adam

Graduate teaching assistants (GTAs) play a prominent role in chemistry laboratory instruction at research based universities. They teach almost all undergraduate chemistry laboratory courses. However, their role in laboratory instruction has often been overlooked in educational research. Interest in chemistry GTAs has been placed on training and their perceived expectations, but less attention has been paid to their experiences or their potential benefits from teaching. This work was designed to investigate GTAs' experiences in and benefits from laboratory instructional environments. This dissertation includes three related studies on GTAs' experiences teaching in general chemistry laboratories. Qualitative methods were used for each study. First, phenomenological analysis was used to explore GTAs' experiences in an expository laboratory program. Post-teaching interviews were the primary data source. GTAs experiences were described in three dimensions: doing, knowing, and transferring. Gains available to GTAs revolved around general teaching skills. However, no gains specifically related to scientific development were found in this laboratory format. Case-study methods were used to explore and illustrate ways GTAs develop a GTA self-image---the way they see themselves as instructors. Two general chemistry laboratory programs that represent two very different instructional frameworks were chosen for the context of this study. The first program used a cooperative project-based approach. The second program used weekly, verification-type activities. End of the semester interviews were collected and served as the primary data source. A follow-up case study of a new cohort of GTAs in the cooperative problem-based laboratory was undertaken to investigate changes in GTAs' self-images over the course of one semester. Pre-semester and post-semester interviews served as the primary data source. Findings suggest that GTAs' construction of their self-image is shaped through the

WAAVP/Pfizer award for excellence in teaching veterinary parasitology: teaching of veterinary parasitology--quo vadis?

PubMed

Eckert, J

2000-02-29

Some thoughts on training and recruitment of academic teachers and future trends in teaching veterinary parasitology are presented with emphasis on the European situation. It is underlined that research is an indispensable basis for academic teaching. Besides a broad scientific background of the teacher, motivation and teaching methods are also important. Many academic teachers do not receive formal training in teaching methods. In order to improve future education, training of staff members in teaching methods should be promoted. Quality control of teaching and research, already established in many schools, should generally be introduced. Teaching is mostly underestimated in relation to research. Therefore, more weight should be placed on the former both in selecting scientists for the career as academic teachers and in evaluating and ranking departments for their academic activities. In the future veterinary medicine will have to cope with profound changes in the society and the veterinary profession, and the progressing European unification will enhance trends for internationalizing teaching curricula. Therefore, veterinary medicine has to reconsider the teaching subjects and methods and to lay more emphasis on flexibility, skills of problem-solving and self-learning and on training for life-long learning. At present there is an ongoing discussion on the question how to teach veterinary medicine, including veterinary parasitology. There are various options, and some of them are discussed, namely, the disciplinary and the problem-based/organ-focussed approaches. It is concluded that for teaching of veterinary parasitology and related disciplines a combined disciplinary and problem-based approach offers the best chances for fulfilling the requirements of teaching for the future. In the curriculum of undergraduate teaching of veterinary medicine at least 70-90 h should be dedicated to veterinary parasitology using a disciplinary and taxonomic approach. Additional

Teaching Improvisation through Processes. Applications in Music Education and Implications for General Education

PubMed Central

Biasutti, Michele

2017-01-01

Improvisation is an articulated multidimensional activity based on an extemporaneous creative performance. Practicing improvisation, participants expand sophisticated skills such as sensory and perceptual encoding, memory storage and recall, motor control, and performance monitoring. Improvisation abilities have been developed following several methodologies mainly with a product-oriented perspective. A model framed under the socio-cultural theory of learning for designing didactic activities on processes instead of outcomes is presented in the current paper. The challenge is to overcome the mere instructional dimension of some practices of teaching improvisation by designing activities that stimulate self-regulated learning strategies in the students. In the article the present thesis is declined in three ways, concerning the following three possible areas of application: (1) high-level musical learning, (2) musical pedagogy with children, (3) general pedagogy. The applications in the music field focusing mainly on an expert's use of improvisation are discussed. The last section considers how these ideas should transcend music studies, presenting the benefits and the implications of improvisation activities for general learning. Moreover, the application of music education to the following cognitive processes are discussed: anticipation, use of repertoire, emotive communication, feedback and flow. These characteristics could be used to outline a pedagogical method for teaching music improvisation based on the development of reflection, reasoning, and meta-cognition. PMID:28626441

Sgr A* and general relativity

NASA Astrophysics Data System (ADS)

Johannsen, Tim

2016-06-01

General relativity has been widely tested in weak gravitational fields but still stands largely untested in the strong-field regime. According to the no-hair theorem, black holes in general relativity depend only on their masses and spins and are described by the Kerr metric. Mass and spin are the first two multipole moments of the Kerr spacetime and completely determine all higher-order moments. The no-hair theorem and, hence, general relativity can be tested by measuring potential deviations from the Kerr metric affecting such higher-order moments. Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, is a prime target for precision tests of general relativity with several experiments across the electromagnetic spectrum. First, near-infrared (NIR) monitoring of stars orbiting around Sgr A* with current and new instruments is expected to resolve their orbital precessions. Second, timing observations of radio pulsars near the Galactic center may detect characteristic residuals induced by the spin and quadrupole moment of Sgr A*. Third, the event horizon telescope, a global network of mm and sub-mm telescopes, aims to study Sgr A* on horizon scales and to image the silhouette of its shadow cast against the surrounding accretion flow using very-long baseline interferometric (VLBI) techniques. Both NIR and VLBI observations may also detect quasiperiodic variability of the emission from the accretion flow of Sgr A*. In this review, I discuss our current understanding of the spacetime of Sgr A* and the prospects of NIR, timing, and VLBI observations to test its Kerr nature in the near future.

The status of experimental tests of general relativity and of theoretical frameworks for analysing them are reviewed. Einstein's equivalence principle (EEP) is well supported by experiments such as the Eötvös experiment, tests of special relativity, and the gravitational redshift experiment. Future tests of EEP and of the inverse square law will search for new interactions arising from unification or quantum gravity. Tests of general relativity at the post-Newtonian level have reached high precision, including the light defl ection the Shapiro time delay, the perihelion advance of Mercury, and the Nordtvedt effect in lunar motion. Gravitational wave damping has been detected in an amount that agrees with general relativity to half a percent using the Hulse-Taylor binary pulsar, and new binary pulsar systems may yield further improvements. When direct observation of gravitational radiation from astrophysical sources begins, new tests of general relativity will be possible.

An evaluation of the relative efficacy of and children's preferences for teaching strategies that differ in amount of teacher directedness.

PubMed

Heal, Nicole A; Hanley, Gregory P; Layer, Stacy A

2009-01-01

The manner in which teachers mediate children's learning varies across early childhood classrooms. In this study, we used a multielement design to evaluate the efficacy of three commonly implemented strategies that varied in teacher directedness for teaching color- and object-name relations. Strategy 1 consisted of brief exposure to the target relations followed by an exclusively child-led play period in which correct responses were praised. Strategy 2 was similar except that teachers prompted the children to vocalize relations and corrected errors via model prompts. Strategy 3 incorporated the same procedures as Strategy 2 except that a brief period of teacher-initiated trials was arranged; these trials involved the use of prompt delay between questions and prompts, and correct responses resulted in tokens and back-up activity reinforcers. Children's preferences for the different teaching strategies were also directly assessed. Strategy 3 was most effective in promoting the acquisition and generalization of the color- and object-name relations and was also most preferred by the majority of children, Strategy 1 was the least effective, and Strategy 2 was typically the least preferred. Implications for the design of early educational environments based on evidence-based values are discussed.

The aim of this study is to examine the relationship among pre-service science teachers' personality traits, academic self-regulation and teaching self-efficacy by proposing and testing a conceptual model. For the specified purpose, 1794 pre-service science teachers participated in the study. The Teachers' Sense of Efficacy Scale, the NEO Five-Factor Inventory, and the Motivated Strategies for Learning Questionnaire were administered to assess pre-service science teachers' teaching self-efficacy, personality, and academic self-regulation respectively. Results showed that agreeableness, neuroticism, performance approach goals, and use of metacognitive strategies are positively linked to different dimensions of teaching self-efficacy, namely self-efficacy for student engagement, instructional strategies, and classroom management. In general, while agreeableness and neuroticism were found to be positively associated with different facets of self-regulation and teaching self-efficacy, openness was found to be negatively linked to these adaptive outcomes.

General Relativity and Spacetime Relationism.

NASA Astrophysics Data System (ADS)

Hoefer, Carl

1992-01-01

This dissertation takes up the project of showing that, in the context of the general theory of relativity (GTR), spacetime relationism is not a refuted or hopeless view, as many in the recent literature have maintained (John Earman, Michael Friedman, and others). Most of the challenges to the relationist view in General Relativity can be satisfactorily answered; in addition, the opposing absolutist and substantivalist views of spacetime can be shown to be problematic. The crucial burden for relationists concerned with GTR is to show that the realistic cosmological models, i.e. those that may be roughly accurate representations of our universe, satisfy Mach's ideas about the origin of inertia. This dissertation clears the way for and begins such a demonstration. After a brief discussion of the problem of the nature of spacetime and its history in the Introduction, chapters 2 and 3 provide conceptual analysis and criticism of contemporary philosophical arguments about relationism, absolutism, and particularly substantivalism. The current best arguments in favor of substantivalism are shown to be flawed, with the exception of the argument from inertial and metrical structure; and on this issue, it is shown that both relationism and substantivalism need to argue for modifications of GTR (restriction of its models to those with certain features) in order to have a non-trivial explanation of inertial and metrical structure. For relationists, a Machian account of the origin of inertia in some models of GTR is required. Chapter 4 demonstrates that such a Machian account is equivalent to the demand for a truly general relativity of motion. Chapter 5 explores the history of Einstein's commitment to Mach's ideas in his work on GTR. Through an examination of the history of Einstein's attempts to impose Machian constraints on the models of General Relativity, further insight into the nature of this problem is obtained, as are reasons to believe that the project is by no means

(4) How can complexity thinking be utilized to shape day-to-day physical education (PE) and coaching practices? (5) How can game making/designing be helpfully utilized for emergent learning? (6) How could purposeful game design create constraints that enable tactical understanding and skill development through adaptive learning and distributed cognition? (7) How can teacher/coach development programs benefit from game-centered approaches? (8) How can TGfU-related approaches be implemented in teacher or coach education with the goal of facilitating preservice and in-service teachers/coaches’ learning to teach and thereby foster their professional development from novices to experienced practitioners? (9) Can the TGfU approach be considered a helpful model across different cultures? (10) Can physical/psychomotor, cognitive, affective/social, and cultural development be fostered via TGfU approaches? The answers to these questions are critical not only for the advancement of teaching and coaching in PE and sport-based clubs, but also for an in-depth discussion on new scientific avenues and technological tools.

Einstein's equivalence principle (EEP) is well supported by experiments such as the Eötvös experiment, tests of local Lorentz invariance and clock experiments. Ongoing tests of EEP and of the inverse square law are searching for new interactions arising from unification or quantum gravity. Tests of general relativity at the post-Newtonian level have reached high precision, including the light deflection, the Shapiro time delay, the perihelion advance of Mercury, the Nordtvedt effect in lunar motion, and frame-dragging. Gravitational wave damping has been detected in an amount that agrees with general relativity to better than half a percent using the Hulse-Taylor binary pulsar, and a growing family of other binary pulsar systems is yielding new tests, especially of strong-field effects. Current and future tests of relativity will center on strong gravity and gravitational waves.

Structures in general relativity

NASA Astrophysics Data System (ADS)

Tieu, Steven

Structures within general relativity are examined. The differences between man-made structures and those predicted by the Einstein differential equations are very subtle. Exotic structures such as the Godel Universe and the Gott cosmic string are examined with emphasis on closed time-like curves. Newtonian models are seen to also have an exotic aspect in that a vast halo consisting of unknown matter dominates the galaxy. We introduce a model for galaxies based on a general relativity framework with the goal of excluding such artifacts from the system while describing the flat-rotation curves. Structures within this model were speculated to be exotic but after close scrutiny, their nature is shown to be benign. Numerical approaches are applied to model four galaxies: The Milky Way, NGC 3031, NGC 3198 and NGC 7331. Density and mass are deduced from these models and compared to the Newtonian models. Within the visible/HI region, there is 30% reduction in total mass. Extending the model to 10 times beyond the HI region using various fall-off scenerios, it is shown that there is only modest increase of the accumulated mass. In comparison to the Newtonian approach to galactic dynamics, the massive halos are not required to account for the flat velocity profiles.

To understand how implementing a daily team huddle affected the function of a complex interprofessional team including learners. A qualitative descriptive study using semi-structured interviews in focus groups. An academic general practice teaching practice. All members of one interprofessional team, including nurses, general practitioners, junior doctors, and support staff. Focus group interviews using semi-structured guidance were transcribed and the results analysed using qualitative content analysis. Four interrelated themes were identified: communication and knowledge sharing; efficiency of care; relationship and team building; and shared responsibility for team function. The implementation of the daily team huddle was seen by participants to enhance the collaboration within the team and to contribute to work life enjoyment. Participants perceived that problems were anticipated and solved quickly. Clinical updates and information about patients benefited the team including learners. Junior doctors quickly understood the scope of practice of other team members, but some felt reluctant to offer clinical opinions. The implementation of a daily team huddle was viewed as worthwhile by this large interprofessional general practice team. The delivery of patient care was more efficient, knowledge was readily distributed, and problem solving was shared across the team, including junior doctors.

General very special relativity in Finsler cosmology

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kouretsis, A. P.; Stathakopoulos, M.; Stavrinos, P. C.

2009-05-15

General very special relativity (GVSR) is the curved space-time of very special relativity (VSR) proposed by Cohen and Glashow. The geometry of general very special relativity possesses a line element of Finsler geometry introduced by Bogoslovsky. We calculate the Einstein field equations and derive a modified Friedmann-Robertson-Walker cosmology for an osculating Riemannian space. The Friedmann equation of motion leads to an explanation of the cosmological acceleration in terms of an alternative non-Lorentz invariant theory. A first order approach for a primordial-spurionic vector field introduced into the metric gives back an estimation of the energy evolution and inflation.

Teaching undergraduate biomechanics with Just-in-Time Teaching.

PubMed

Riskowski, Jody L

2015-06-01

Biomechanics education is a vital component of kinesiology, sports medicine, and physical education, as well as for many biomedical engineering and bioengineering undergraduate programmes. Little research exists regarding effective teaching strategies for biomechanics. However, prior work suggests that student learning in undergraduate physics courses has been aided by using the Just-in-Time Teaching (JiTT). As physics understanding plays a role in biomechanics understanding, the purpose of study was to evaluate the use of a JiTT framework in an undergraduate biomechanics course. This two-year action-based research study evaluated three JiTT frameworks: (1) no JiTT; (2) mathematics-based JiTT; and (3) concept-based JiTT. A pre- and post-course assessment of student learning used the biomechanics concept inventory and a biomechanics concept map. A general linear model assessed differences between the course assessments by JiTT framework in order to evaluate learning and teaching effectiveness. The results indicated significantly higher learning gains and better conceptual understanding in a concept-based JiTT course, relative to a mathematics-based JiTT or no JiTT course structure. These results suggest that a course structure involving concept-based questions using a JiTT strategy may be an effective method for engaging undergraduate students and promoting learning in biomechanics courses.

Fienup, Daniel M; Covey, Daniel P; Critchfield, Thomas S

2010-03-01

Instructional interventions based on stimulus equivalence provide learners with the opportunity to acquire skills that are not directly taught, thereby improving the efficiency of instructional efforts. The present report describes a study in which equivalence-based instruction was used to teach college students facts regarding brain anatomy and function. The instruction involved creating two classes of stimuli that students understood as being related. Because the two classes shared a common member, they spontaneously merged, thereby increasing the yield of emergent relations. Overall, students mastered more than twice as many facts as were explicitly taught, thus demonstrating the potential of equivalence-based instruction to reduce the amount of student investment that is required to master advanced academic topics.

The LIGO detection of GW150914 provides an unprecedented opportunity to study the two-body motion of a compact-object binary in the large-velocity, highly nonlinear regime, and to witness the final merger of the binary and the excitation of uniquely relativistic modes of the gravitational field. We carry out several investigations to determine whether GW150914 is consistent with a binary black-hole merger in general relativity. We find that the final remnant's mass and spin, as determined from the low-frequency (inspiral) and high-frequency (postinspiral) phases of the signal, are mutually consistent with the binary black-hole solution in general relativity. Furthermore, the data following the peak of GW150914 are consistent with the least-damped quasinormal mode inferred from the mass and spin of the remnant black hole. By using waveform models that allow for parametrized general-relativity violations during the inspiral and merger phases, we perform quantitative tests on the gravitational-wave phase in the dynamical regime and we determine the first empirical bounds on several high-order post-Newtonian coefficients. We constrain the graviton Compton wavelength, assuming that gravitons are dispersed in vacuum in the same way as particles with mass, obtaining a 90%-confidence lower bound of 1013 km . In conclusion, within our statistical uncertainties, we find no evidence for violations of general relativity in the genuinely strong-field regime of gravity.

The purpose of this study was to determine if parents and teachers differed in their views of adolescent storm and stress, and to examine the relations of these reported perceptions with parenting and teaching behaviors. Subjects were parents and teachers of middle and high school students in three school districts in the Midwest. Storm and stress beliefs were identified as parents' and teachers' perceptions of conflict, moodiness, and risk-taking behavior. Scales assessing classic/conforming and positive adolescent behaviors also were included. Self-report assessments of parenting and teaching were administered as well. Results indicated that whereas both parents and teachers held storm and stress beliefs, teachers maintained stronger perceptions than parents. Teachers also endorsed higher classic/conforming and lower positive behaviors than did parents. The results further indicated that parents' perceptions of storm and stress were related to their degree of parental responsiveness; but teachers' perceptions were not related to their teaching style. These results suggest that stereotypic beliefs of the adolescent period continue to be maintained, and that these may influence how adults interact with adolescents.

The uncertainty principle in quantum mechanics is a fundamental relation with different forms, including Heisenberg's uncertainty relation and Schrödinger's uncertainty relation. We introduce the generalized Wigner-Yanase-Dyson correlation and the related quantities. Various properties of them are discussed. Finally, we establish several generalizations of uncertainty relation expressed in terms of the generalized Wigner-Yanase-Dyson skew information.

The aim of this cross-sectional study was to investigate the influence of job-related autonomy and social support provided by consultants and colleagues on the stress-related health complaints of surgical residents in the Netherlands. All (n = 400) Dutch residents in training in general surgery were sent validated self-report questionnaires. Odds ratios were calculated predicting health and exposure to long-term stress for gender, number of working hours, type of hospital, level of social support, job-related autonomy and training phase. The interactions between job-related autonomy and level of social support provided by consultants and colleagues, and all variables, were analysed. A total of 254 of 400 (64%) residents returned questionnaires that were eligible for analysis. Residents experienced more health complaints than the average member of the Dutch working population (4.0 versus 2.5; p = 0.000). Male and senior residents were significantly 'healthier' than female and junior residents, respectively. Social support by consultants was a strong predictor of health and social support by colleagues showed a significant interaction with gender. Women and residents in university hospitals experienced less social support by consultants than men and residents in general teaching hospitals. Residents working in university hospitals experienced lower levels of job-related autonomy and less support from colleagues in comparison with those working in general teaching hospitals. A working week of > 60 hours adversely affected health and job-related autonomy. Social support provided by consultants and colleagues, and job control, are important factors that interact with the work-associated, stress-related health of residents in training in general surgery. Residents report a greater number of health complaints than the average member of the working population, especially female and junior residents. General teaching hospitals seem to provide better support at work than

For several years numerical simulations have been revealing the details of general relativity's predictions for the dynamical interactions of merging black holes. I will review what has been learned of the rich phenomenology of these mergers and the resulting gravitational wave signatures. These wave forms provide a potentially observable record of the powerful astronomical events, a central target of gravitational wave astronomy. Asymmetric radiation can produce a thrust on the system which may accelerate the single black hole resulting from the merger to high relative velocity.

Academic work at different career stages has changed and a broadened portfolio of expertise enables academics to adapt, maintain and advance their career. Development related to research activity is naturally driven by methodology and technology. Institutions and peers largely support development in the contexts of dissemination, measuring impact and obtaining funding. A European Commission High Level Group recommended pedagogic training for everyone teaching in Higher Education by 2020 with mandatory continuing professional development and with academic staff recruitment and promotion being linked to teaching performance. Early career teaching experience is already an expectation, and advantage is gained by developing recognized teaching expertise. More senior academics gain an advantage through recognition of higher levels of expertise, also covering elements of leadership and innovation in teaching. This review aims to raise awareness particularly of teaching-related skills within the dimensions of academic professional development in Higher Education, outlining some general directions for development and recognition in context of current challenges to support planning and identifying training needs and opportunities at different career stages. © FEMS 2015.

Graduate teaching assistants (GTAs) are used extensively as undergraduate science lab instructors at universities, yet they often have having minimal instructional training and little is known about effective training methods. This blind randomized control trial study assessed the impact of two training regimens on GTA teaching effectiveness. GTAs teaching undergraduate biology labs (n = 52) completed five hours of training in either inquiry-based learning pedagogy or general instructional “best practices”. GTA teaching effectiveness was evaluated using: (1) a nine-factor student evaluation of educational quality; (2) a six-factor questionnaire for student learning; and (3) course grades. Ratings from both GTAs and undergraduates indicated that indicated that the inquiry-based learning pedagogy training has a positive effect on GTA teaching effectiveness. PMID:24147138

BOOK REVIEW: Partial Differential Equations in General Relativity

NASA Astrophysics Data System (ADS)

Halburd, Rodney G.

2008-11-01

Although many books on general relativity contain an overview of the relevant background material from differential geometry, very little attention is usually paid to background material from the theory of differential equations. This is understandable in a first course on relativity but it often limits the kinds of problems that can be studied rigorously. Einstein's field equations lie at the heart of general relativity. They are a system of partial differential equations (PDEs) relating the curvature of spacetime to properties of matter. A central part of most problems in general relativity is to extract information about solutions of these equations. Most standard texts achieve this by studying exact solutions or numerical and analytical approximations. In the book under review, Alan Rendall emphasises the role of rigorous qualitative methods in general relativity. There has long been a need for such a book, giving a broad overview of the relevant background from the theory of partial differential equations, and not just from differential geometry. It should be noted that the book also covers the basic theory of ordinary differential equations. Although there are many good books on the rigorous theory of PDEs, methods related to the Einstein equations deserve special attention, not only because of the complexity and importance of these equations, but because these equations do not fit into any of the standard classes of equations (elliptic, parabolic, hyperbolic) that one typically encounters in a course on PDEs. Even specifying exactly what ones means by a Cauchy problem in general relativity requires considerable care. The main problem here is that the manifold on which the solution is defined is determined by the solution itself. This means that one does not simply define data on a submanifold. Rendall's book gives a good overview of applications and results from the qualitative theory of PDEs to general relativity. It would be impossible to give detailed

The LIGO detection of GW150914 provides an unprecedented opportunity to study the two-body motion of a compact-object binary in the large-velocity, highly nonlinear regime, and to witness the final merger of the binary and the excitation of uniquely relativistic modes of the gravitational field. We carry out several investigations to determine whether GW150914 is consistent with a binary black-hole merger in general relativity. We find that the final remnant's mass and spin, as determined from the low-frequency (inspiral) and high-frequency (postinspiral) phases of the signal, are mutually consistent with the binary black-hole solution in general relativity. Furthermore, the data following the peak of GW150914 are consistent with the least-damped quasinormal mode inferred from the mass and spin of the remnant black hole. By using waveform models that allow for parametrized general-relativity violations during the inspiral and merger phases, we perform quantitative tests on the gravitational-wave phase in the dynamical regime and we determine the first empirical bounds on several high-order post-Newtonian coefficients. We constrain the graviton Compton wavelength, assuming that gravitons are dispersed in vacuum in the same way as particles with mass, obtaining a 90%-confidence lower bound of 10^{13}  km. In conclusion, within our statistical uncertainties, we find no evidence for violations of general relativity in the genuinely strong-field regime of gravity.

What is general relativity?

NASA Astrophysics Data System (ADS)

Coley, Alan A.; Wiltshire, David L.

2017-05-01

General relativity is a set of physical and geometric principles, which lead to a set of (Einstein) field equations that determine the gravitational field and to the geodesic equations that describe light propagation and the motion of particles on the background. But open questions remain, including: what is the scale on which matter and geometry are dynamically coupled in the Einstein equations? Are the field equations valid on small and large scales? What is the largest scale on which matter can be coarse grained while following a geodesic of a solution to Einstein’s equations? We address these questions. If the field equations are causal evolution equations, whose average on cosmological scales is not an exact solution of the Einstein equations, then some simplifying physical principle is required to explain the statistical homogeneity of the late epoch Universe. Such a principle may have its origin in the dynamical coupling between matter and geometry at the quantum level in the early Universe. This possibility is hinted at by diverse approaches to quantum gravity which find a dynamical reduction to two effective dimensions at high energies on one hand, and by cosmological observations which are beginning to strongly restrict the class of viable inflationary phenomenologies on the other. We suggest that the foundational principles of general relativity will play a central role in reformulating the theory of spacetime structure to meet the challenges of cosmology in the 21st century.

Derivation of Einstein-Cartan theory from general relativity

NASA Astrophysics Data System (ADS)

Petti, Richard

2015-04-01

General relativity cannot describe exchange of classical intrinsic angular momentum and orbital angular momentum. Einstein-Cartan theory fixes this problem in the least invasive way. In the late 20th century, the consensus view was that Einstein-Cartan theory requires inclusion of torsion without adequate justification, it has no empirical support (though it doesn't conflict with any known evidence), it solves no important problem, and it complicates gravitational theory with no compensating benefit. In 1986 the author published a derivation of Einstein-Cartan theory from general relativity, with no additional assumptions or parameters. Starting without torsion, Poincaré symmetry, classical or quantum spin, or spinors, it derives torsion and its relation to spin from a continuum limit of general relativistic solutions. The present work makes the case that this computation, combined with supporting arguments, constitutes a derivation of Einstein-Cartan theory from general relativity, not just a plausibility argument. This paper adds more and simpler explanations, more computational details, correction of a factor of 2, discussion of limitations of the derivation, and discussion of some areas of gravitational research where Einstein-Cartan theory is relevant.

Provision of undergraduate otorhinolaryngology teaching within General Medical Council approved UK medical schools: what is current practice?

PubMed

Khan, M M; Saeed, S R

2012-04-01

Despite longstanding concern, provision of undergraduate ENT teaching has not improved in response to the aims of the UK General Medical Council's initiative Tomorrow's Doctors. Previous studies have demonstrated poor representation of ENT within the undergraduate curriculum. We aimed to identify current practice in order to establish undergraduate ENT experience across UK medical schools, a timely endeavour in light of the General Medical Council's new 2011-2013 education strategy. Questionnaires were sent to ENT consultants, medical school deans and students. All schools with a clinical curriculum were anonymously represented. Our outcome measures were the provision of mandatory or optional ENT placements, and their duration and content. A compulsory ENT placement was available to over half (53 per cent) of the students. Ten of the 26 participating schools did not offer an ENT attachment. The mean mandatory placement was 8 days. Overall, 38 per cent of students reported a satisfactory compulsory ENT placement. Most ENT consultants questioned considered that newly qualified doctors were not proficient in managing common ENT problems that did not require specialist referral. Little improvement in the provision of undergraduate ENT teaching was demonstrated. An increase in the proportion of students undertaking ENT training is necessary. Time and curriculum constraints on medical schools mean that optimisation of available resources is required.

Generalization of Pain-Related Fear Based on Conceptual Knowledge.

PubMed

Meulders, Ann; Vandael, Kristof; Vlaeyen, Johan W S

2017-05-01

Increasing evidence suggests that pain-related fear is key to the transition from acute to chronic pain. Previous research has shown that perceptual similarity with a pain-associated movement fosters the generalization of fear to novel movements. Perceptual generalization of pain-related fear is adaptive as it enables individuals to extrapolate the threat value of one movement to another without the necessity to learn anew. However, excessive spreading of fear to safe movements may become maladaptive and may lead to sustained anxiety, dysfunctional avoidance behaviors, and severe disability. A hallmark of human cognition is the ability to extract conceptual knowledge from a learning episode as well. Although this conceptual pathway may be important to understand fear generalization in chronic pain, research on this topic is lacking. We investigated acquisition and generalization of concept-based pain-related fear. During acquisition, unique exemplars of one action category (CS+; e.g., opening boxes) were followed by pain, whereas exemplars of another action category (CS-; e.g., closing boxes) were not. Subsequently, spreading of pain-related fear to novel exemplars of both action categories was tested. Participants learned to expect the pain to occur and reported more pain-related fear to the exemplars of the CS+ category compared with those of the CS- category. During generalization, fear and expectancy generalized to novel exemplars of the CS+ category, but not to the CS- category. This pattern was not corroborated in the eyeblink startle measures. This is the first study that demonstrates that pain-related fear can be acquired and generalized based on conceptual knowledge. Copyright © 2016. Published by Elsevier Ltd.

Giant pulsar glitches in full general relativity

NASA Astrophysics Data System (ADS)

Sourie, A.; Chamel, N.; Novak, J.; Oertel, M.

2017-12-01

We present recent numerical simulations of giant pulsar glitches, as observed in the emblematic Vela pulsar, based on a two-fluid model, including for the first time all general-relativistic effects and realistic equations of state. In particular, we focus on modelling the vortex-mediated transfer of angular momentum that takes place during the spin-up stage from the neutron superfluid to the charged particles through dissipative mutual friction forces. Taking general relativity into account does not only modify the structure of the star but also leads to a new coupling between the fluids arising from frame-dragging effects. As a consequence, general relativity can strongly affect the global dynamics of pulsar glitches : the errors on the value of the characteristic rise time incurred by using Newtonian gravity are thus found to be as large as ˜ 40 % for the models considered.

Research on teaching methods.

PubMed

Oermann, M H

1990-01-01

Research on teaching methods in nursing education was categorized into studies on media, CAI, and other nontraditional instructional strategies. While the research differed, some generalizations may be made from the findings. Multimedia, whether it is used for individual or group instruction, is at least as effective as traditional instruction (lecture and lecture-discussion) in promoting cognitive learning, retention of knowledge, and performance. Further study is needed to identify variables that may influence learning and retention. While learner attitudes toward mediated instruction tended to be positive, investigators failed to control for the effect of novelty. Control over intervening variables was lacking in the majority of studies as well. Research indicated that CAI is as effective as other teaching methods in terms of knowledge gain and retention. Attitudes toward CAI tended to be favorable, with similar problems in measurement as those evidenced in studies of media. Chang (1986) also recommends that future research examine the impact of computer-video interactive instruction on students, faculty, and settings. Research is needed on experimental teaching methods, strategies for teaching problem solving and clinical judgment, and ways of improving the traditional lecture and discussion. Limited research in these areas makes generalizations impossible. There is a particular need for research on how to teach students the diagnostic reasoning process and encourage critical thinking, both in terms of appropriate teaching methods and the way in which those strategies should be used. It is interesting that few researchers studied lecture and lecture-discussion except as comparable teaching methods for research on other strategies. Additional research questions may be generated on lecture and discussion in relation to promoting concept learning, an understanding of nursing and other theories, transfer of knowledge, and development of cognitive skills.

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

NASA Astrophysics Data System (ADS)

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.

2011-06-06

This article explores various models and ideas for future sustainable general practice vocational training supervision in Australia. The general practitioner supervisor in the clinical practice setting is currently central to training the future general practice workforce. Finding ways to recruit, retain and motivate both new and experienced GP teachers is discussed, as is the creation of career paths for such teachers. Some of the newer methods of practice-based teaching are considered for further development, including vertically integrated teaching, e-learning, wave consulting and teaching on the run, teaching teams and remote teaching. Approaches to supporting and resourcing teaching and the required infrastructure are also considered. Further research into sustaining the practice-based general practice supervision model will be required.

Clinical teaching: widening the definition.

PubMed

Thampy, Harish; Agius, Steven; Allery, Lynne

2014-06-01

In all medical specialities, trainees are increasingly encouraged to develop teaching skills alongside their clinical professional development. However, there have been few empirical UK-based studies that have examined trainees' attitudes and understanding of their own engagement with educational activities. This study therefore aimed to explore this in the context of general practitioner (GP) training using a qualitative approach. Twenty GP registrars from the North Western Deanery were recruited to four focus groups. The data obtained using a semi-structured topic guide were analysed for thematic content, and the rigour of this methodology was increased by peer checking of the coding. Participation was voluntary and ethical approval was obtained. The majority of registrars interviewed initially presumed that teaching role development was only in relation to educating those junior to them, and thus followed a vertical hierarchical structure; however, during focus group discussions, the registrars started to recognise a range of other teaching modalities that they had not previously noted. These included peer-to-peer teaching sessions, examination preparation groups and, indeed, the everyday education of patients during consultations. Although this study has been conducted in the context of GP training, it is plausible to suggest that skewed perceptions from trainees as to what constitutes teaching may indeed exist in other speciality training schemes. There is therefore a need to shift current thinking around teaching engagement away from the traditional senior-junior relationship, and instead widen the definition of what it means to be involved in teaching activities. © 2014 John Wiley & Sons Ltd.

The current challenges of teaching ESP

NASA Astrophysics Data System (ADS)

Fălăuş, A.

2017-05-01

Although the status of lingua franca can easily be claimed by English nowadays, there are always plenty of challenges involved in the process of teaching a foreign language. The simple mastering of the four skills (reading, writing, listening and speaking) and the acquisition of general grammar and vocabulary may not be enough in some circumstances. ESP focuses on the specific needs of the learners, concentrating more on language in context and on the students’ need to acquire a set of professional skills and particular job-related functions. This paper, consequently, focuses on identifying the current challenges that teachers and students may encounter in the process of teaching and learning English for Specific Purposes.

Leadership skills teaching in Yorkshire & the Humber - a survey: uncovering, sharing, developing, embedding.

PubMed

Fowler, Iolanthe; Gill, Andy

2015-09-01

Medical leadership is a hot topic, but it is not known yet how to teach this most effectively. A working party of educators in Yorkshire and the Humber (Y&H) studied the leadership domains, as set out in the Medical Leadership Competency Framework and from this distilled a set of 'trainable' leadership skills, which were felt to be important to teach during general practitioner (GP) training. A questionnaire was sent out to a large GP educational community (educators and trainees) within Y&H to establish the following: (i) whether the distilled skills were thought to have face validity when applied to the concept of leadership, (ii) what was the relative importance of these skills in relation to each other and (iii) the degree to which these skills were already being taught in practice placements and at General Practice Specialty Training Programme (GPSTP) teaching sessions.Educators reported more teaching and training occurring than trainees reported receiving, and the relative importance of the skills sets were different between educators and trainees. It was evident that leadership skills are currently being taught, but that making training explicitly 'leadership', and raising the importance of leadership skills in GP, may address some of these imbalances. Educators requested guidance on how to teach these skills effectively and commented that many existing opportunities for leadership teaching and training are not well recognised or used. Routinely and regularly offering the chance for trainees at all levels to be exposed to leadership skills by role modelling, making use of everyday opportunities in practice to teach and encouraging trainee involvement in projects and opportunities to practice new skills can facilitate the acquisition and celebration of mastery of generic leadership skills.

To determine the characteristics of curricula for teaching the content of clinical practice guidelines (CPGs) in psychiatric residency and child and adolescent fellowship programs as well as to determine if and how the learning of CPG content is applied in clinical care settings. We conducted a national online survey of directors of general psychiatry residency and child and adolescent fellowship programs in the USA. The survey questionnaire included 13 brief questions about the characteristics used to teach CPGs in the programs, as well as two demographic questions about each program and director. Descriptive statistics were reported for each questionnaire item by program classification (i.e., child and adolescent vs. general psychiatry). The survey response rate was 49.8% (146 out of 293). Just 23% of programs reported having written goals and objectives related to teaching CPGs. The most frequently taught aspect of CPGs was their content (72% of programs). Didactic sessions were the most frequently employed teaching strategy (79% of programs). Regarding the application of CPG learning in treatment care settings, just 16% of programs applied algorithms in care settings, and 15% performed evaluations to determine consistency between CPG recommendations and care delivery. Only 8% of programs utilized audit and feedback to residents about their adherence to CPGs. Faculty time constraints and insufficient interest were the leading barriers (39% and 33% of programs, respectively) to CPG teaching, although 38% reported no barriers. However, child and adolescent programs less commonly identified insufficient interest among faculty as a barrier to teaching CPGs compared to general programs (20% vs. 43%). Moreover, compared to general programs, child and adolescent fellowship programs taught more aspects of CPGs, used more educational activities to teach the content of specific CPGs, and used more methods to evaluate the teaching of CPGs. Although the majority of programs

Galileons as the scalar analogue of general relativity

NASA Astrophysics Data System (ADS)

Klein, Remko; Ozkan, Mehmet; Roest, Diederik

2016-02-01

We establish a correspondence between general relativity with diffeomorphism invariance and scalar field theories with Galilean invariance: notions such as the Levi-Civita connection and the Riemann tensor have a Galilean counterpart. This suggests Galilean theories as the unique nontrivial alternative to gauge theories (including general relativity). Moreover, it is shown that the requirement of first-order Palatini formalism uniquely determines the Galileon models with second-order field equations, similar to the Lovelock gravity theories. Possible extensions are discussed.

BOOK REVIEW: A First Course in General Relativity (Second Edition) A First Course in General Relativity (Second Edition)

Poisson, Eric

2010-05-01

A few years ago, in my review of Sean Carroll's book in Classical and Quantum Gravity [1], I wrote that while the 1970s was the decade of Weinberg [2] and Misner, Thorne and Wheeler [3], and while the eighties was the decade of Schutz [4] and Wald [5], the 2000s was clearly the decade of Hartle [6] and Carroll [7]. In my opinion, these books continue to stand out in the surprisingly dense crowd of introductory textbooks on general relativity. At the dawn of this new decade I look forward to see what fresh pedagogical insights will be produced next, and who will be revealed as the winners of the 2010s. It is, of course, much too early to tell, but Schutz is back, and he will set the standard just as he did back in 1985. This is the long-awaited second edition of his `First Course', a short, accessible, and very successful introduction to general relativity. The changes from the first edition are modest: Schutz wisely refrained from bloating the text with new topics, and limited himself to updating his discussion of gravitational-wave sources and detectors, neutron-star and black-hole astrophysics, and suggestions for further reading. Most importantly, he completely rewrote the chapter on cosmology, a topic that has evolved enormously since the first edition. The book begins in chapter 1 with a beautiful review of special relativity that emphasizes spacetime geometry and stays away from an algebraic approach based on the Lorentz transformation, which appears only later in the chapter. This is followed up in chapters 2 and 3 with an introduction to vector and tensor analysis in flat spacetime. The point of view is modern (tensors are defined as linear mapping of vectors and one-forms into real numbers) but the presentation is very accessible and avoids an overload of mathematical fine print. In chapter 4 the book introduces the spacetime description of fluids; it is here that the energy-momentum tensor makes its first appearance. The move to curved spacetime is

Evaluation of a modified team based learning method for teaching general embryology to 1st year medical graduate students.

Shankar, Nachiket; Roopa, R

2009-01-01

To encourage student participation in the learning process, the authors introduced a modified team based learning (TBL) method to cover two general embryology topics in the 1st year MBBS curriculum. The aim of this study was to evaluate students' perception of this method vis-à-vis the lecture method of teaching. A questionnaire was used to survey and evaluate the perceptions of 1st year MBBS students at the Department of Anatomy at our medical college in India. A total of eight classes were allotted to cover General Embryology. Six of these classes were conducted using the traditional didactic lecture method. Two topics were covered using the modified TBL method. Five teams of students were constituted, and each team was given handouts which contained basic factual material, four clinical case histories, and previous university exam questions from the topic. On the day of the session, these were discussed in the presence of the faculty facilitator. Students evaluated these sessions through a questionnaire. A majority of students felt that the modified TBL sessions were better at fulfilling learning objectives (46 students, 85%), enabled better understanding (43 students, 79%), were more interesting (43 students, 81%), ensured greater student participation (51 students, 94%) and involved greater effort on the part of students (53 students, 98%), as compared to traditional teaching methods. Most of the students (43 students, 79%) opined that more such sessions should be organized in the future. Responses from students show that the modified TBL classes could be utilized judiciously along with the traditional didactic lectures for teaching embryology.

Different habitus: different strategies in teaching physics? Relationships between teachers' social, economic and cultural capital and strategies in teaching physics in upper secondary school

NASA Astrophysics Data System (ADS)

Engström, Susanne; Carlhed, Carina

2014-09-01

With environmental awareness in the societies of today, political steering documents emphasize that all education should include sustainable development. But it seems to be others competing ideals for teaching physics, or why do the physics teachers teach as they do? Physics teachers in secondary school in Sweden have generally, been focused on facts and a strong link with scientific theories and concepts. In general, the curriculum sway the teaching, a standard text book in physics is used, the teaching is organized according to the book and the teacher deals with and demonstrates typical tasks on the whiteboard and group work is common for special issues related to tasks from the textbook or elaborating. The aim with this study is to analyze why physics teachers in upper secondary school choose to teach energy as they do. Data emerging from a questionnaire focused on indicators of the teachers' cultural and economic assets, or capital, according to the work of Pierre Bourdieu's sociology. Especially his concept on life styles and habitus provide a tool for analysis. We focus on physics teachers' positions in the social space, dispositions and standpoints towards the ideal way to teach physics in upper secondary school (n = 268). Our response rate is 29 % and due to the low response rate a non response bias analysis was made. In our analysis we primarily sought for groups, with a cluster analysis based on the teaching practice, revealed common features for both what and how they teach and three different teaching types emerged. Then we reconstructed the group habitus of the teachers by analyzing dispositions and standpoints and related those to the specific polarization of sacred values, that is struggles about the natural order (doxa) in the social space of science education, which is a part of and has boundaries to dominating fields like the natural sciences and the political fields (curriculum etc.). Three teacher-groups' habituses are described and analyzed

Teaching group theory using Rubik's cubes

NASA Astrophysics Data System (ADS)

Cornock, Claire

2015-10-01

Being situated within a course at the applied end of the spectrum of maths degrees, the pure mathematics modules at Sheffield Hallam University have an applied spin. Pure topics are taught through consideration of practical examples such as knots, cryptography and automata. Rubik's cubes are used to teach group theory within a final year pure elective based on physical examples. Abstract concepts, such as subgroups, homomorphisms and equivalence relations are explored with the cubes first. In addition to this, conclusions about the cubes can be made through the consideration of algebraic approaches through a process of discovery. The teaching, learning and assessment methods are explored in this paper, along with the challenges and limitations of the methods. The physical use of Rubik's cubes within the classroom and examination will be presented, along with the use of peer support groups in this process. The students generally respond positively to the teaching methods and the use of the cubes.

The effects of a summer science camp teaching experience on preservice elementary teachers' science teaching efficacy, science content knowledge, and understanding of the nature of science

NASA Astrophysics Data System (ADS)

Logerwell, Mollianne G.

The purpose of this study was to investigate the impact of a summer science camp teaching experience on preservice elementary teachers' science teaching efficacy, science content knowledge, and understanding of the nature of science. Master's degree students enrolled in the elementary Fairfax Partnership Schools (FPS, n = 21) cohort served as the treatment group, while those enrolled in the Loudoun Partnership Schools (LPS, n = 15) and Professional Development Schools (PDS, n = 24) cohorts at George Mason University served as the control groups. The treatment group planned for and taught a two-week inquiry- and problem-based summer science camp as part of their science methods course, while the control groups did not. The Science Teaching Efficacy Belief Instrument (STEBI), a science content assessment, a personal data questionnaire, and a modified version of the Views of Nature of Science Questionnaire (VNOS-C) were administered to the participants at the beginning and end of their science methods course. Analyses revealed significant increases for the FPS group in general science teaching efficacy, personal science teaching efficacy, science teaching outcome expectancy, general science knowledge, biology content knowledge, chemistry content knowledge, and understanding of NOS; the LPS group in general science teaching efficacy, personal science teaching efficacy, chemistry content knowledge, and understanding of NOS; and, the PDS group in general science teaching efficacy, personal science teaching efficacy, and chemistry content knowledge. Additionally, the FPS group had significantly higher general science teaching efficacy than both control groups, personal science teaching efficacy than the PDS group, and understanding of NOS than the LPS group. Overall, the findings indicate that course length is not as important for developing preservice teachers' teaching efficacy and understanding of content as having connected, authentic field-based teaching experiences

The arrival times of the pulses from each pulsar are measured by a cesium clock. The observations are all made at a frequency of 2388 MHz (12.5 cm wavelength) on a 26 m dish antenna. The effect of interstellar charged particles is a random one that increases the noise level on the arrival time measurements. The variation in clock rate is shown consisting of two effects: the time dilation effect of special relativity and the red shift effect of general relativity.

Gravitation experiments at Stanford. [using general relativity theory

NASA Technical Reports Server (NTRS)

Lipa, J. A.

1980-01-01

The experimental situation in post-Newtonian gravitation is briefly reviewed in order to reexamine the extent to which experiment supports or refutes general relativity. A description is given of the equivalence principle project, the gyroscope experiment, and the search for gravity waves. It is noted that even though some doubt has been cast on the value of the perihelion advance and the gravitational redshift as precise tests of general relativity in the past few years, many competing theories have been ruled out; in particular, the results from the Viking mission significantly reduce the credibility of the Brans-Dicke theory (Brans and Dicke, 1961). The dimensionless constant omega in this theory is now forced to exceed 50, while the value originally proposed was 6 (omega being infinity in general relativity). It is noted that the gyro experiment described is capable of putting much tighter limits on this parameter, and together with the other experiments in progress will help place gravitational theory on a firmer experimental footing.

2008-01-01

This article presents the results obtained using a new tool for measuring psychosocial burdens in teaching profession--the Questionnaire of Occupational Burdens in Teaching (QOBT). In its first theoretical part, some typologies of stressors in teaching, developed in other countries, are presented and the need to construct a new tool in Poland is discussed. In this part, the construction process of the new tool and its three scales comprising: Conflict Situations, Organizational Burdens and Lack of Work Sense are described. The psychometric features of the new questionnaire (e.g., Cronbach a = 0.63-0.84) are also given. The results are based on a large random sample of teachers from the Łódz voivodeship. The results did not show significant differences in the level of occupational burdens between men and women. Generally, neither are seniority and age related to the level of burdens. One exception are Organizational burdens that slightly more affect older teachers. The study also showed the need to incorporate the activities at the organizational level into programs on occupational stress.

Effective and responsible teaching of climate change in Earth Science-related disciplines

NASA Astrophysics Data System (ADS)

Robinson, Z. P.; Greenhough, B. J.

2009-04-01

Climate change is a core topic within Earth Science-related courses. This vast topic covers a wide array of different aspects that could be covered, from past climatic change across a vast range of scales to environmental (and social and economic) impacts of future climatic change and strategies for reducing anthropogenic climate change. The Earth Science disciplines play a crucial role in our understanding of past, present and future climate change and the Earth system in addition to understanding leading to development of strategies and technological solutions to achieve sustainability. However, an increased knowledge of the occurrence and causes of past (natural) climate changes can lead to a lessened concern and sense of urgency and responsibility amongst students in relation to anthropogenic causes of climatic change. Two concepts integral to the teaching of climate change are those of scientific uncertainty and complexity, yet an emphasis on these concepts can lead to scepticism about future predictions and a further loss of sense of urgency. The requirement to understand the nature of scientific uncertainty and think and move between different scales in particular relating an increased knowledge of longer timescale climatic change to recent (industrialised) climate change, are clearly areas of troublesome knowledge that affect students' sense of responsibility towards their role in achieving a sustainable society. Study of the attitudes of university students in a UK HE institution on a range of Earth Science-related programmes highlights a range of different attitudes in the student body towards the subject of climate change. Students express varied amounts of ‘climate change saturation' resulting from both media and curriculum coverage, a range of views relating to the significance of humans to the global climate and a range of opinions about the relevance of environmental citizenship to their degree programme. Climate change is therefore a challenging

The Transformation of Teaching Habits in Relation to the Introduction of Grading and National Testing in Science Education in Sweden

NASA Astrophysics Data System (ADS)

Lidar, Malena; Lundqvist, Eva; Ryder, Jim; Östman, Leif

2017-12-01

In Sweden, a new curriculum and new methods of assessment (grading of students and national tests) in science education were introduced in grade 6 in 2012/2013. We have investigated what implications these reforms have for teachers' teaching and assessment practices in order to explore the question of how teachers transform their teaching habits in relation to policy reforms. Interviews with 16 teachers teaching science in grade 6 (Y6), over 3 years after the reforms were introduced, were analysed. Building on the ideas of John Dewey, we consider teachers' talk about their everyday practice as expressions of their habits of teaching. Habits of teaching are related both to individual experiences as well as institutional traditions in and about teaching. A categorisation of educational philosophies was used to teachers' habits of teaching to a collective level and to show how habits can be transformed and developed over time in specific sociocultural contexts. The teachers were categorised as using essentialist and/or progressivist educational philosophy. In the responses to the introduction of grading and national testing, the teachers took three approaches: Their habits being reinforced, revised or unchanged in relation to the reforms. Although the responses were different, a striking similarity was that all teachers justified their responses with wanting to do what is best for students. However, how to show care for students differed, from delivering scientific knowledge in alignment with an essentialist educational philosophy, to preparing students to do well on tests, to supporting their development as individuals, which is in alignment with a progressivist educational philosophy.

General relativity at 75: how right was einstein?

PubMed

Will, C M

1990-11-09

The status of experimental tests of general relativity is reviewed on the occasion of its 75th anniversary. Einstein's equivalence principle is well supported by experiments such as the Eötvös experiment, tests of special relativity, and the gravitational redshift experiment. Tests of general relativity have reached high precision, including the light deflection and the perihelion advance of Mercury, proposed by Einstein 75 years ago, and new tests such as the Shapiro time delay and the Nordtvedt effect in lunar motion. Gravitational wave damping has been detected to an accuracy of 1 percent on the basis of measurements of the binary pulsar. The status of the "fifth force" is discussed, along with the frontiers of experimental relativity, including proposals for testing relativistic gravity with advanced technology and spacecraft.

Recently a new quantum generalization of the Rényi divergence and the corresponding conditional Rényi entropies was proposed. Here, we report on a surprising relation between conditional Rényi entropies based on this new generalization and conditional Rényi entropies based on the quantum relative Rényi entropy that was used in previous literature. Our result generalizes the well-known duality relation H(A|B) + H(A|C) = 0 of the conditional von Neumann entropy for tripartite pure states to Rényi entropies of two different kinds. As a direct application, we prove a collection of inequalities that relate different conditional Rényi entropies and derive a new entropicmore » uncertainty relation.« less

This study investigated the longitudinal relation between general well-being and self-esteem of male adolescents with severe psychiatric disorders. Moreover, the transition out of secure residential care was studied. Adolescents ( N = 172) were assessed three times with 6 months between each assessment. The sample comprised adolescents who were admitted throughout the entire study ( n = 116) and who had been discharged at 6/12 months follow-up ( n = 56). General well-being and self-esteem were stable concepts over time. The relation between general well-being and self-esteem differed for both groups. Among the admitted group general well-being positively predicted self-esteem and self-esteem negatively predicted general well-being from Time 2 to Time 3. Among the discharged adolescents, self-esteem at Time 1 positively predicted general well-being at Time 2 and general well-being at Time 2 positively predicted self-esteem at Time 3. Changing social contexts, as well as problems experienced during the transition out of secure care, might affect this relationship.

Going interactive: six strategies to meet the challenge of teaching electrosurgery to general dental practitioners.

PubMed

Davies, B R; Millar, B J; Louca, C

2007-10-27

Mandatory continuing professional development has resulted in a recent expansion in postgraduate dental teaching. One popular type of teaching is the practical 'hands-on' course that combines the explanation of theory with the acquisition of practical skills in small groups. The challenge to dental teachers is to provide the best level of teaching on these courses where the course participants bring varied expectations and different levels of knowledge, skill or interest. This paper presents a new teaching model that has been developed for the postgraduate teaching of Electrosurgery. The key components of this course include an interactive theory lecture using multimedia, followed by hands-on practical teaching. The emphasis throughout is on the use of facilitation and group learning rather than traditional didactic teaching. A series of strategies for the effective delivery of such a hands-on course together with evaluation of findings from 31 courses are considered.

Doppler frequency in interplanetary radar and general relativity

NASA Technical Reports Server (NTRS)

Mcvittie, G. C.

1972-01-01

The change of frequency of an interplanetary radar signal sent from the earth to another planet or to a space probe is worked out according to general relativity. The Schwarzschild spacetime is employed and its null geodesics control the motion of the signals. Exact Doppler frequency formulas are derived for one-way and two-way radar in terms of an arbitrary Schwarzschild radial coordinate. A reduction to the special relativity case is used to interpret the formulas in terms of the relative radial velocity of emitter and target. The general relativity corrections are worked out approximately for each of three possible Schwarzschild radial coordinates, and a numerical example is given. The amount of the correction is different according as one or the other of the Schwarzschild coordinates is identified with the radius vector deduced from classical celestial mechanics. The identification problem is discussed.

Network technology has become a creative tool of changing human productivity, the rapid development of it has brought profound changes to our learning, working and life. Network technology has many advantages such as rich contents, various forms, convenient retrieval, timely communication and efficient combination of resources. Network information resources have become the new education resources, get more and more application in the education, has now become the teaching and learning tools. Network teaching enriches the teaching contents, changes teaching process from the traditional knowledge explanation into the new teaching process by establishing situation, independence and cooperation in the network technology platform. The teacher's role has shifted from teaching in classroom to how to guide students to learn better. Network environment only provides a good platform for the teaching, we can get a better teaching effect only by constantly improve the teaching content. Changchun university of science and technology introduced a BB teaching platform, on the platform, the whole optical classroom teaching and the classroom teaching can be improved. Teachers make assignments online, students learn independently offline or the group learned cooperatively, this expands the time and space of teaching. Teachers use hypertext form related knowledge of applied optics, rich cases and learning resources, set up the network interactive platform, homework submission system, message board, etc. The teaching platform simulated the learning interest of students and strengthens the interaction in the teaching.

The present paper shows that general relativity in the Arnowitt-Deser-Misner formalism admits a BV-BFV formulation. More precisely, for any d + 1 ≠ 2 (pseudo-) Riemannian manifold M with space-like or time-like boundary components, the BV data on the bulk induces compatible BFV data on the boundary. As a byproduct, the usual canonical formulation of general relativity is recovered in a straightforward way.

2014-03-19

Medical students, junior hospital doctors on rotation and general practice (GP) registrars are undertaking their training in clinical general practices in increasing numbers in Australia. Some practices have four levels of learner. This study aimed to explore how multi-level teaching (also called vertical integration of GP education and training) is occurring in clinical general practice and the impact of such teaching on the learner. A qualitative research methodology was used with face-to-face, semi-structured interviews of medical students, junior hospital doctors, GP registrars and GP teachers in eight training practices in the region that taught all levels of learners. Interviews were audio-recorded and transcribed. Qualitative analysis was conducted using thematic analysis techniques aided by the use of the software package N-Vivo 9. Primary themes were identified and categorised by the co-investigators. 52 interviews were completed and analysed. Themes were identified relating to both the practice learning environment and teaching methods used.A practice environment where there is a strong teaching culture, enjoyment of learning, and flexible learning methods, as well as learning spaces and organised teaching arrangements, all contribute to positive learning from a learners' perspective.Learners identified a number of innovative teaching methods and viewed them as positive. These included multi-level learner group tutorials in the practice, being taught by a team of teachers, including GP registrars and other health professionals, and access to a supernumerary GP supervisor (also termed "GP consultant teacher"). Other teaching methods that were viewed positively were parallel consulting, informal learning and rural hospital context integrated learning. Vertical integration of GP education and training generally impacted positively on all levels of learner. This research has provided further evidence about the learning culture, structures and teaching

Implications of a positive cosmological constant for general relativity.

PubMed

Ashtekar, Abhay

2017-10-01

Most of the literature on general relativity over the last century assumes that the cosmological constant [Formula: see text] is zero. However, by now independent observations have led to a consensus that the dynamics of the universe is best described by Einstein's equations with a small but positive [Formula: see text]. Interestingly, this requires a drastic revision of conceptual frameworks commonly used in general relativity, no matter how small [Formula: see text] is. We first explain why, and then summarize the current status of generalizations of these frameworks to include a positive [Formula: see text], focusing on gravitational waves.

The evolution of teaching.

Fogarty, L; Strimling, P; Laland, K N

2011-10-01

Teaching, alongside imitation, is widely thought to underlie the success of humanity by allowing high-fidelity transmission of information, skills, and technology between individuals, facilitating both cumulative knowledge gain and normative culture. Yet, it remains a mystery why teaching should be widespread in human societies but extremely rare in other animals. We explore the evolution of teaching using simple genetic models in which a single tutor transmits adaptive information to a related pupil at a cost. Teaching is expected to evolve where its costs are outweighed by the inclusive fitness benefits that result from the tutor's relatives being more likely to acquire the valuable information. We find that teaching is not favored where the pupil can easily acquire the information on its own, or through copying others, or for difficult to learn traits, where teachers typically do not possess the information to pass on to relatives. This leads to a narrow range of traits for which teaching would be efficacious, which helps to explain the rarity of teaching in nature, its unusual distribution, and its highly specific nature. Further models that allow for cumulative cultural knowledge gain suggest that teaching evolved in humans because cumulative culture renders otherwise difficult-to-acquire valuable information available to teach. © 2011 The Author(s).

Learning-Related Shifts in Generalization Gradients for Complex Sounds

PubMed Central

Wisniewski, Matthew G.; Church, Barbara A.; Mercado, Eduardo

2010-01-01

Learning to discriminate stimuli can alter how one distinguishes related stimuli. For instance, training an individual to differentiate between two stimuli along a single dimension can alter how that individual generalizes learned responses. In this study, we examined the persistence of shifts in generalization gradients after training with sounds. University students were trained to differentiate two sounds that varied along a complex acoustic dimension. Students subsequently were tested on their ability to recognize a sound they experienced during training when it was presented among several novel sounds varying along this same dimension. Peak shift was observed in Experiment 1 when generalization tests immediately followed training, and in Experiment 2 when tests were delayed by 24 hours. These findings further support the universality of generalization processes across species, modalities, and levels of stimulus complexity. They also raise new questions about the mechanisms underlying learning-related shifts in generalization gradients. PMID:19815929

Generalized transformations and coordinates for static spherically symmetric general relativity

NASA Astrophysics Data System (ADS)

Hill, James M.; O'Leary, Joseph

2018-04-01

We examine a static, spherically symmetric solution of the empty space field equations of general relativity with a non-orthogonal line element which gives rise to an opportunity that does not occur in the standard derivations of the Schwarzschild solution. In these derivations, convenient coordinate transformations and dynamical assumptions inevitably lead to the Schwarzschild solution. By relaxing these conditions, a new solution possibility arises and the resulting formalism embraces the Schwarzschild solution as a special case. The new solution avoids the coordinate singularity associated with the Schwarzschild solution and is achieved by obtaining a more suitable coordinate chart. The solution embodies two arbitrary constants, one of which can be identified as the Newtonian gravitational potential using the weak field limit. The additional arbitrary constant gives rise to a situation that allows for generalizations of the Eddington-Finkelstein transformation and the Kruskal-Szekeres coordinates.

Factors related to successful teaching by outstanding professors: an interpretive study.

PubMed

Rossetti, Jeanette; Fox, Patricia G

2009-01-01

The purpose of this study was to identify and describe factors associated with successful university teaching within the cultural norms of a public university in the midwestern United States. An interpretive analysis was conducted using the educational philosophy and goal statements of 35 university professors who received Presidential Teaching Awards from the university. The professors' diverse disciplines included nursing, curriculum and instruction, accountancy, music, and political science. The authors offer nursing educators the opportunity to increase their confidence and effectiveness by "learning" from faculty members who have been recognized as exceptionally successful in teaching. Four main relevant themes associated with successful university teaching were identified: Presence, Promotion of Learning, Teachers as Learners, and Enthusiasm. The narratives of the professors helped define the meaning of successful teaching across disciplines and offer nursing faculty additional perspectives and experiences.

Learning to teach effectively: Science, technology, engineering, and mathematics graduate teaching assistants' teaching self-efficacy

NASA Astrophysics Data System (ADS)

Dechenne, Sue Ellen

Graduate teaching assistants (GTAs) from science, technology, engineering, and mathematics (STEM) are important in the teaching of undergraduate students (Golde & Dore, 2001). However, they are often poorly prepared for teaching (Luft, Kurdziel, Roehrig, & Turner, 2004). This dissertation addresses teaching effectiveness in three related manuscripts: (1) A position paper that summarizes the current research on and develops a model of GTA teaching effectiveness. (2) An adaptation and validation of two instruments; GTA perception of teaching training and STEM GTA teaching self-efficacy. (3) A model test of factors that predict STEM GTA teaching self-efficacy. Together these three papers address key questions in the understanding of teaching effectiveness in STEM GTAs including: (a) What is our current knowledge of factors that affect the teaching effectiveness of GTAs? (b) Given that teaching self-efficacy is strongly linked to teaching performance, how can we measure STEM GTAs teaching self-efficacy? (c) Is there a better way to measure GTA teaching training than currently exists? (d) What factors predict STEM GTA teaching self-efficacy? An original model for GTA teaching effectiveness was developed from a thorough search of the GTA teaching literature. The two instruments---perception of training and teaching self-efficacy---were tested through self-report surveys using STEM GTAs from six different universities including Oregon State University (OSU). The data was analyzed using exploratory and confirmatory factor analysis. Using GTAs from the OSU colleges of science and engineering, the model of sources of STEM GTA teaching self-efficacy was tested by administering self-report surveys and analyzed by using OLS regression analysis. Language and cultural proficiency, departmental teaching climate, teaching self-efficacy, GTA training, and teaching experience affect GTA teaching effectiveness. GTA teaching self-efficacy is a second-order factor combined from self

Generating perfect fluid spheres in general relativity

NASA Astrophysics Data System (ADS)

Boonserm, Petarpa; Visser, Matt; Weinfurtner, Silke

2005-06-01

Ever since Karl Schwarzschild’s 1916 discovery of the spacetime geometry describing the interior of a particular idealized general relativistic star—a static spherically symmetric blob of fluid with position-independent density—the general relativity community has continued to devote considerable time and energy to understanding the general-relativistic static perfect fluid sphere. Over the last 90 years a tangle of specific perfect fluid spheres has been discovered, with most of these specific examples seemingly independent from each other. To bring some order to this collection, in this article we develop several new transformation theorems that map perfect fluid spheres into perfect fluid spheres. These transformation theorems sometimes lead to unexpected connections between previously known perfect fluid spheres, sometimes lead to new previously unknown perfect fluid spheres, and in general can be used to develop a systematic way of classifying the set of all perfect fluid spheres.

Is Prediction Possible in General Relativity?

NASA Astrophysics Data System (ADS)

Manchak, John Byron

2008-04-01

Here we briefly review the concept of “prediction” within the context of classical relativity theory. We prove a theorem asserting that one may predict one’s own future only in a closed universe. We then question whether prediction is possible at all (even in closed universes). We note that interest in prediction has stemmed from considering the epistemological predicament of the observer. We argue that the definitions of prediction found thus far in the literature do not fully appreciate this predicament. We propose a more adequate alternative and show that, under this definition, prediction is essentially impossible in general relativity.

Solving the Hamilton-Jacobi equation for general relativity

Parry, J.; Salopek, D. S.; Stewart, J. M.

1994-03-01

We demonstrate a systematic method for solving the Hamilton-Jacobi equation for general relativity with the inclusion of matter fields. The generating functional is expanded in a series of spatial gradients. Each term is manifestly invariant under reparametrizations of the spatial coordinates (``gauge invariant''). At each order we solve the Hamiltonian constraint using a conformal transformation of the three-metric as well as a line integral in superspace. This gives a recursion relation for the generating functional which then may be solved to arbitrary order simply by functionally differentiating previous orders. At fourth order in spatial gradients we demonstrate solutions for irrotational dust as well as for a scalar field. We explicitly evolve the three-metric to the same order. This method can be used to derive the Zel'dovich approximation for general relativity.

Einstein's theory of gravity, General Relativity, has been precisely tested on Solar System scales, but the long-range nature of gravity is still poorly constrained. The nearby strong gravitational lens ESO 325-G004 provides a laboratory to probe the weak-field regime of gravity and measure the spatial curvature generated per unit mass, γ. By reconstructing the observed light profile of the lensed arcs and the observed spatially resolved stellar kinematics with a single self-consistent model, we conclude that γ = 0.97 ± 0.09 at 68% confidence. Our result is consistent with the prediction of 1 from General Relativity and provides a strong extragalactic constraint on the weak-field metric of gravity.

An exploration of equitable science teaching practices for students with learning disabilities

NASA Astrophysics Data System (ADS)

Morales, Marlene

Teaching Science to Students with Learning Disabilities Inventory, the case study teachers demonstrated characteristics of successful teachers of diverse learners developed by Lynch (2000). Overall, the qualitative findings revealed that the case study teachers were unsure how to provide equitable science teaching practices to all students, particularly to students with learning disabilities. They provided students with a variety of learning experiences that entailed high expectations for all; however, these experiences were similar for all students. Had the teachers fully implemented equitable science teaching practices, students would have had multiple options for taking in the information and making sense of it in each lesson. Teaching that includes using a variety of validated practices that take into account students' individualized learning needs can promote aspects of equitable science teaching practices. Finally, this study provides implications for teacher education programs and professional development programs. As teachers implement science education reform efforts related to equitable science teaching practices, both teacher education programs and professional development programs should include opportunities for teachers to reflect on their beliefs about how students with learning disabilities learn and provide them with a variety of validated teaching practices that will assist them in teaching students with learning disabilities in the general education classroom while implementing science reform efforts.

Medical records in General Practice/Family Medicine are an essential information support on the health status of the patient and a communication document between health professionals. The development of competencies in General Practice/Family Medicine during pre-graduation must include the ability to make adequate medical records in practical context. As of 2012, medicine students at the University of Beira Interior have been performing visits using the Subjective, Objective, Assessment and Plan - SOAP methodology, with a performance evaluation of the visit, with the aim to check on which Subjective, Objective, Assessment and Plan - SOAP aspects students reveal the most difficulties in order to define improvement techniques and to correlate patient grade with tutor evaluation. Analysing the evaluation data for the 2015 - 2016 school year at the General Practice/Family Medicine visit carried out by fourth year students in medicine, comparing the averages of each item in the Subjective, Objective, Assessment and Plan - SOAP checklist and the patient evaluation. In the Subjective, Objective, Assessment and Plan - SOAP, 29.7% of students are on the best grade quartile, 37.1% are on the best competencies quartile and 27.2% on the best patient grade quartile. 'Evolution was verified/noted' received the worst grades in Subjective, 'Record of physical examination focused on the problem of the visit' received the worst grades in Objective, 'Notes of Diagnostic reasoning / differential diagnostic' received de worst grades in Assessment and 'Negotiation of aims to achieve' received the worst grades in Plan. The best tutor evaluation is found in 'communication'. Only one single study evaluated student´s performance under examination during a visit, with similar results to the present one and none addressed the patient's evaluation. Students revealed a good performance in using the Subjective, Objective, Assessment and Plan - SOAP. The findings represent the beginning of the

Affine generalization of the Komar complex of general relativity

NASA Astrophysics Data System (ADS)

Mielke, Eckehard W.

2001-02-01

On the basis of the ``on shell'' Noether identities of the metric-affine gauge approach of gravity, an affine superpotential is derived which comprises the energy- and angular-momentum content of exact solutions. In the special case of general relativity (GR) or its teleparallel equivalent, the Komar or Freud complex, respectively, are recovered. Applying this to the spontaneously broken anti-de Sitter gauge model of McDowell and Mansouri with an induced Euler term automatically yields the correct mass and spin of the Kerr-AdS solution of GR with a (induced) cosmological constant without the factor two discrepancy of the Komar formula.

The learner’s perspective in GP teaching practices with multi-level learners: a qualitative study

PubMed Central

2014-01-01

Background Medical students, junior hospital doctors on rotation and general practice (GP) registrars are undertaking their training in clinical general practices in increasing numbers in Australia. Some practices have four levels of learner. This study aimed to explore how multi-level teaching (also called vertical integration of GP education and training) is occurring in clinical general practice and the impact of such teaching on the learner. Methods A qualitative research methodology was used with face-to-face, semi-structured interviews of medical students, junior hospital doctors, GP registrars and GP teachers in eight training practices in the region that taught all levels of learners. Interviews were audio-recorded and transcribed. Qualitative analysis was conducted using thematic analysis techniques aided by the use of the software package N-Vivo 9. Primary themes were identified and categorised by the co-investigators. Results 52 interviews were completed and analysed. Themes were identified relating to both the practice learning environment and teaching methods used. A practice environment where there is a strong teaching culture, enjoyment of learning, and flexible learning methods, as well as learning spaces and organised teaching arrangements, all contribute to positive learning from a learners’ perspective. Learners identified a number of innovative teaching methods and viewed them as positive. These included multi-level learner group tutorials in the practice, being taught by a team of teachers, including GP registrars and other health professionals, and access to a supernumerary GP supervisor (also termed “GP consultant teacher”). Other teaching methods that were viewed positively were parallel consulting, informal learning and rural hospital context integrated learning. Conclusions Vertical integration of GP education and training generally impacted positively on all levels of learner. This research has provided further evidence about the

Optical drift effects in general relativity

NASA Astrophysics Data System (ADS)

Korzyński, Mikołaj; Kopiński, Jarosław

2018-03-01

We consider the question of determining the optical drift effects in general relativity, i.e. the rate of change of the apparent position, redshift, Jacobi matrix, angular distance and luminosity distance of a distant object as registered by an observer in an arbitrary spacetime. We present a fully relativistic and covariant approach, in which the problem is reduced to a hierarchy of ODE's solved along the line of sight. The 4-velocities and 4-accelerations of the observer and the emitter and the geometry of the spacetime along the line of sight constitute the input data. We build on the standard relativistic geometric optics formalism and extend it to include the time derivatives of the observables. In the process we obtain two general, non-perturbative relations: the first one between the gravitational lensing, represented by the Jacobi matrix, and the apparent position drift, also called the cosmic parallax, and the second one between the apparent position drift and the redshift drift. The applications of the results include the theoretical study of the drift effects of cosmological origin (so-called real-time cosmology) in numerical or exact Universe models.

2018-05-01

There are many reasons for evaluating our approach and improving our teaching of America's future doctors, whether they become anesthesiologists (recruitment) or participate in patient management in the perioperative period (general patient care). Teaching medical students the seminal aspects of any medical specialty is a continual challenge. Although no definitive curricula or single clinical approach has been defined, certain key features can be ascertained from clinical experience and the literature. A survey was conducted among US anesthesiology teaching programs regarding the teaching content and approaches currently used to teach US medical students clinical anesthesia. Using the Accreditation Council for Graduate Medical Education website that lists 133 accredited anesthesiology programs, residency directors were contacted via e-mail. Based on those responses and follow-up phone calls, teaching representatives from 125 anesthesiology departments were identified and asked via e-mail to complete a survey. The survey was returned by 85 programs, yielding a response rate of 68% of individuals contacted and 63% of all departments. Ninety-one percent of the responding departments teach medical students, most in the final 2 years of medical school. Medical student exposure to clinical anesthesia occurred as elective only at 42% of the institutions, was requirement only at 16% of responding institutions, and the remainder had both elective and required courses. Anesthesiology faculty at 43% of the responding institutions reported teaching in the preclinical years of medical school, primarily in the departments of pharmacology and physiology. Forty-five percent of programs reported interdisciplinary teaching with other departments teaching classes such as gross anatomy. There is little exposure of anesthesiology faculty to medical students in other general courses. Teaching in the operating room is the primary teaching method in the clinical years. Students are

The pragmatic mapping process and its variants have proven effective in second language learning and teaching. The goal of this paper is to show that the same process applies in teaching and intervention with disordered populations. A secondary goal, ultimately more important, is to give clinicians, teachers, and other educators a tool-kit, or a framework, from which they can evaluate and implement interventions. What is offered is an introduction to a general theory of signs and some examples of how it can be applied in treating communication disorders. (1) Readers will be able to relate the three theoretical consistency requirements to language teaching and intervention. (2) Readers will be introduced to a general theory of signs that provides a basis for evaluating and implementing interventions.

Undergraduate students majoring in forestry generally reflect that genetics is one of the most difficult compul-sory courses, because the traditional teaching method is difficult to satisfy their needs. According to the theoretical charac-teristics of forestry and actual demands of the students, in the light of teaching and research experience in recent years, we adopted a series of typical genetic cases such as 'opening coffin to identify relatives', stem-throne of Lycium ruthenicum Murr, and magic powers in Harry Potter. Our practices revealed that the case teaching in genetics could train good personality traits, learning abilities and creativity of the students, stimulate their interests and initiatives in learning, and increase systematic learning.

Simple recursion relations for general field theories

Cheung, Clifford; Shen, Chia -Hsien; Trnka, Jaroslav

2015-06-17

On-shell methods offer an alternative definition of quantum field theory at tree-level, replacing Feynman diagrams with recursion relations and interaction vertices with a handful of seed scattering amplitudes. In this paper we determine the simplest recursion relations needed to construct a general four-dimensional quantum field theory of massless particles. For this purpose we define a covering space of recursion relations which naturally generalizes all existing constructions, including those of BCFW and Risager. The validity of each recursion relation hinges on the large momentum behavior of an n-point scattering amplitude under an m-line momentum shift, which we determine solely from dimensionalmore » analysis, Lorentz invariance, and locality. We show that all amplitudes in a renormalizable theory are 5-line constructible. Amplitudes are 3-line constructible if an external particle carries spin or if the scalars in the theory carry equal charge under a global or gauge symmetry. Remarkably, this implies the 3-line constructibility of all gauge theories with fermions and complex scalars in arbitrary representations, all supersymmetric theories, and the standard model. Moreover, all amplitudes in non-renormalizable theories without derivative interactions are constructible; with derivative interactions, a subset of amplitudes is constructible. We illustrate our results with examples from both renormalizable and non-renormalizable theories. In conclusion, our study demonstrates both the power and limitations of recursion relations as a self-contained formulation of quantum field theory.« less

Training innovative talents, as one of the major aims for Chinese universities, needs to reform the traditional teaching methods. The research-oriented teaching method has been introduced and its connotation and significance for Chinese university teaching have been discussed for years. However, few practical teaching methods for routine class teaching were proposed. In this paper, a comprehensive and concrete research-oriented teaching model with contents of reference value and evaluation method for class teaching was proposed based on the current teacher-guiding teaching model in China. We proposed that the research-oriented teaching model should include at least seven aspects on: (1) telling the scientific history for the skills to find out scientific questions; (2) replaying the experiments for the skills to solve scientific problems; (3) analyzing experimental data for learning how to draw a conclusion; (4) designing virtual experiments for learning how to construct a proposal; (5) teaching the lesson as the detectives solve the crime for learning the logic in scientific exploration; (6) guiding students how to read and consult the relative references; (7) teaching students differently according to their aptitude and learning ability. In addition, we also discussed how to evaluate the effects of the research-oriented teaching model in examination.

This study aims to investigate how teachers' motivation to teach is related to different teaching styles. A hundred and seventy six physical education teachers from five European countries participated in the study. Teachers' motivation was measured using an instrument developed by Roth et al., 2007 based on the Self-Determination Theory (Deci and Ryan, 1985) which was tested for suitability for use with physical education teachers. The use of teaching styles was assessed through teachers' self-reported data according to the description of teaching styles presented by Curtner-Smith et al., 2001. The revised confirmatory factor model of the teachers' motivation instrument, with three factors, met the criteria for satisfactory fit indices. The results showed that teachers were more intrinsically motivated to teach than externally. Cross-cultural comparison indicated that the Spanish teachers were more intrinsically motivated whilst Lithuanian teachers were more externally motivated than teachers from the other four countries. Teachers from all five countries reported a more frequent use of reproductive styles than productive styles. The results of the present study confirmed the hypotheses that teachers' autonomous motivation is related to the student-centered or productive teaching styles whilst non-autonomously motivated teachers adopt more teacher-centered or reproductive teaching styles. Intrinsic and introjected motivation was significantly higher among teachers who more frequently employed productive teaching styles than teachers who used them less frequently. Intrinsically motivated teachers using more productive teaching styles can contribute more to the promotion physical activity among students.

Education in the field of natural disciplines - Mathematics, Physics, Chemistry, Ecology and Biology takes part in general education at all schools on the territory of Slovakia. Its aim is to reach the state of balanced development of all personal characteristics of pupils, to teach them correctly identify and analyse problems, propose solutions and above all how to solve the problem itself. High quality education can be reached only through the pedagogues who have a good expertise knowledge, practical experience and high level of pedagogical abilities. The teacher as a disseminator of natural-scientific knowledge should be not only well-informed about modern tendencies in the field, but he/she also should actively participate in project tasks This is the reason why students of 1st year of study (bachelor degree) at the Department of Physics of Constantine the Philosopher University in Nitra attend lectures in the frame of subject General Chemistry. In this paper we present and describe an e - learning course called General Chemistry that is freely accessible to students. One of the aims of this course is to attract attention towards the importance of cross-curricular approach which seems to be fundamental in contemporary natural-scientific education (e.g. between Physics and Chemistry). This is why it is so important to implement a set of new topics and tasks that support development of abilities to realise cross-curricular goals into the process of preparation of future teachers of Physics.

Applications of invariants in general relativity

NASA Astrophysics Data System (ADS)

Pelavas, Nicos

This thesis explores various kinds of invariants and their use in general relativity. To start, the simplest invariants, those polynomial in the Riemann tensor, are examined and the currently accepted Carminati-Zakhary set is compared to the Carminati-McLenaghan set. A number of algebraic relations linking the two sets are given. The concept of gravitational entropy, as proposed by Penrose, has some physically appealing properties which have motivated attempts to quantify this notion using various invariants. We study this in the context of self-similar spacetimes. A general result is obtained which gives the Lie derivative of any invariant or ratio of invariants along a homothetic trajectory. A direct application of this result shows that the currently used gravitational epoch function fails to satisfy certain criteria. Based on this work, candidates for a gravitational epoch function are proposed that behave accordingly in these models. The instantaneous ergo surface in the Kerr solution is studied and shown to possess conical points at the poles when embedded in three dimensional Euclidean space. These intrinsic singularities had remained undiscovered for a generation. We generalize the Gauss-Bonnet theorem to accommodate these points and use it to compute a topological invariant, the Euler characteristic, for this surface. Interest in solutions admitting a cosmological constant has prompted us to study ergo surfaces in stationary non-asymptotically flat spacetimes. In these cases we show that there is in fact a family of ergo surfaces. By using a kinematic invariant constructed from timelike Killing vectors we try to find a preferred ergo surface. We illustrate to what extent this invariant fails to provide such a measure.

This article describes the workshop "Teaching Child Psychiatric Assessment Skills: Using Mental Health Screening Instruments," presented at the 35th Forum for Behavioral Sciences in Family Medicine on 20 September 2014. The goals of the presentation were (1) to teach family medicine behavioral health educators to use both general and problem-specific mental health screening tools (MHSTs) in their work with trainees to help satisfy the Accreditation Council for Graduate Medical Education (ACGME) mandate for behavioral and mental health experience during family medicine residency, (2) to reflect on how MHSTs might be integrated into the flow of family medicine teaching practices, and (3) to exemplify how evidence-based methods of adult education might be used in teaching such content. One general MHST, the Pediatric Symptom Checklist-17 and one problem-specific MHST for each of the four commonest pediatric mental health issues: for attention-deficit hyperactivity disorder, the Vanderbilt; for Anxiety, the Screen for Childhood Anxiety-Related Emotional Disorders; for Depression, the Patient Health Questionnaire-9 for teens; and for Aggression, the Retrospective-Modified Overt Aggression Scale, were practiced at least twice in the context of a clinical vignette. All of the selected MHSTs are free in the public domain and available for download from the website: www.CAPPCNY.org. Participants were asked to reflect on their own office practice characteristics and consider how MHSTs might be integrated into their systems of care. This workshop could be replicated by others wishing to teach the use of MHSTs in primary care settings or teaching programs. © The Author(s) 2015.

2010-01-01

To explore the views and experiences of general practice (GP) vocational trainees regarding communication skills (CS) and the teaching and learning of these skills. A purposive sample of second and third (final) year GP trainees took part in six focus group (FG) discussions. Transcripts were coded and analysed in accordance with a grounded theory approach by two investigators using Alas-ti software. Finally results were triangulated by means of semi-structured telephone interviews. The analysis led to three thematic clusters: (1) trainees acknowledge the essential importance of communication skills and identified contextual factors influencing the learning and application of these skills; (2) trainees identified preferences for learning and receiving feedback on their communication skills; and (3) trainees perceived that the assessment of communication skills is subjective. These themes are organised into a framework for a better understanding of trainees' communication skills as part of their vocational training. The framework helps in leading to a better understanding of the way in which trainees learn and apply communication skills. The unique context of vocational training should be taken into account when trainees' communication skills are assessed. The teaching and learning should be guided by a learner-centred approach. The framework is valuable for informing curricular reform and future research.

2015-03-01

One hundred years after its birth, general relativity has become a highly successful physical theory in the sense that it has passed a large number of experimental and observational tests and finds extensive application to a wide variety of cosmic phenomena. It remains an active area of research as new tests are on the way, epitomized by the exciting prospect of detecting gravitational waves from merging black holes. General relativity is the essential foundation of the standard model of cosmology and underlies our description of the black holes and neutron stars that are ultimately responsible for the most powerful and dramatic cosmic sources. Its interface with physics on the smallest and largest scales will continue to provide fertile areas of investigation in its next century.

Gravitational redshift of galaxies in clusters as predicted by general relativity.

PubMed

Wojtak, Radosław; Hansen, Steen H; Hjorth, Jens

2011-09-28

The theoretical framework of cosmology is mainly defined by gravity, of which general relativity is the current model. Recent tests of general relativity within the Lambda Cold Dark Matter (ΛCDM) model have found a concordance between predictions and the observations of the growth rate and clustering of the cosmic web. General relativity has not hitherto been tested on cosmological scales independently of the assumptions of the ΛCDM model. Here we report an observation of the gravitational redshift of light coming from galaxies in clusters at the 99 per cent confidence level, based on archival data. Our measurement agrees with the predictions of general relativity and its modification created to explain cosmic acceleration without the need for dark energy (the f(R) theory), but is inconsistent with alternative models designed to avoid the presence of dark matter. © 2011 Macmillan Publishers Limited.

Generalized Onsager's reciprocal relations for the master and Fokker-Planck equations

NASA Astrophysics Data System (ADS)

Peng, Liangrong; Zhu, Yi; Hong, Liu

2018-06-01

The Onsager's reciprocal relation plays a fundamental role in the nonequilibrium thermodynamics. However, unfortunately, its classical version is valid only within a narrow region near equilibrium due to the linear regression hypothesis, which largely restricts its usage. In this paper, based on the conservation-dissipation formalism, a generalized version of Onsager's relations for the master equations and Fokker-Planck equations was derived. Nonlinear constitutive relations with nonsymmetric and positively stable operators, which become symmetric under the detailed balance condition, constitute key features of this new generalization. Similar conclusions also hold for many other classical models in physics and chemistry, which in turn make the current study as a benchmark for the application of generalized Onsager's relations in nonequilibrium thermodynamics.

Stress in doctors and dentists who teach.

PubMed

Rutter, Harry; Herzberg, Joe; Paice, Elisabeth

2002-06-01

To explore the relationship between a teaching role and stress in doctors and dentists who teach. Medline, PubMed, BIDS database for social sciences literature, and the ERIC database for educational literature were searched using the key words 'stress' or 'burnout' with the terms doctor, physician, dentist, teacher, lecturer, academic staff, and university staff. Other books and journals known to the authors were also used. Many studies have shown high levels of stress in doctors, dentists, teachers, and lecturers. A large number of factors are implicated, including low autonomy, work overload, and lack of congruence between power and responsibility. Doctors and dentists who take on a teaching role in addition to their clinical role may increase their levels of stress, but there is also evidence that this dual role may reduce job-related stress. Working as a doctor or dentist may entail higher levels of stress than are experienced by the general population. In some situations adding in the role of teacher reduces this stress, but more research is needed to explain this finding.

Exposure of undergraduate medical students to general practice and community healthcare services is common practice in the international medical curricula. Nevertheless, proponents of the hospital and biotechnology based paradigm, which is still dominant within the medical academic environment, question both the scope and the setting of this training procedure. Regarding the latter, the quality of teaching is often questioned in settings such as rural primary health centers, where health professionals have neither incentives nor accredited training skills. Therefore, the success of community based medical education depends substantially on the procedures implemented to involve non-academic staff as clinical teachers. This report describes the steps taken by the Aristotle University of Thessaloniki (AUTH) Medical School to establish and maintain a Rural Primary Health Care (PHC) Teaching Network in order to implement community oriented PHC and GP undergraduate medical education. A multi-professional teachers' network of healthcare staff, working in Rural Primary Health Centers, has been chosen, in order to expose students to the holistic approach of PHC. The enrollment of teachers to the Teaching Network was solely on a voluntary basis. The novelty of this procedure is that each professional is approached personally, instead through the Health Center (HC) that usually offers this service as a package in similar activities. In an attempt to attract health professionals committed to medical education, a self-selection procedure was adopted. Collaboration with the medical school was established but it was characterized by the School's inability to compensate teachers. A series of 'Training the Trainers' seminars were completed during the first implementation period in order to enhance the awareness of health professionals regarding undergraduate teaching in PHC; to present the educational needs of medical students; to expose them to the principles of medical teaching

In vivo language intervention: unanticipated general effects.

After observing the lack of generalization of language trained in highly structured training sessions using established behavior modification techniques, "incidental teaching" procedures were developed to change the use of specified language behaviors in the natural environment. This paper reports an analysis of the general changes in the language, other than that specifically targeted by the incidental teaching procedures, used by disadvantaged preschool children. The daily language samples of disadvantaged children involved in a previously reported experiment to increase compound sentence usage were reexamined and compared to comparable records of other disadvantaged children and of middle-class children of college parents in order to assess possible general effects of the intervention program. Whereas the language that both groups of comparison children used changed little across the preschool year, the amount of talking by the children in the experimental program increased markedly. Their use of more elaborate vocabulary and more elaborate sentences also increased in direct proportion to the increases in overall language use, such that both language use and language elaboration in the experimental group of children changed from a pattern simlar to the comparison group of disadvantaged children to a pattern similar to the comparison group of middleclass children. It is argued that some general features of the incidental teaching procedure--differentially attending to child overtures and responding relative to the child's selected topic (reinforcer)--contributed to the increase in overall language use beyond the specific language behavior targeted, and that this increase in the probability of children's talking itself resulted in the substantial increases in elaboration seen in the children's spontaneous language. Because, at least in children with fairly well-developed language repertoires, language use is contextually controlled, talking more involves talking

The emergency regarding recent immigration waves into Italy makes continued healthcare monitoring of these populations necessary. Through a survey of hospital admissions carried out during the last five years at the S. Orsola-Malpighi General Hospital of Bologna (Italy), all causes of admission of these subjects were evaluated, together with their correlates. Subsequently, we focused on admissions due to infectious diseases. All available data regarding foreign citizens admitted as inpatients or in Day-Hospital settings of our teaching hospital from January 1, 1999, to March 31, 2004, were assessed. Diagnosis-related group (DRG) features, and single discharge diagnoses, were also evaluated, and a further assessment of infectious diseases was subsequently made. Within a comprehensive pool of 339,051 hospitalized patients, foreign citizen discharges numbered 7,312 (2.15%), including 2,542 males (34.8%) and 4,769 females (65.2%). Males had a mean age of 36.8+/-14.7 years, while females were aged 30.8+/-12.2 years. In the assessment of the areas of origin, 34.6% of hospitalizations were attributed to patients coming from Eastern Europe, 15.3% from Northern Africa, 7.3% (comprehensively) from Western Europe and United States, 6.9% from the Indian subcontinent, 5.9% from sub-Saharan Africa, 5.7% from Latin America, 4.1% from China, 2.5% from the Philippines, and 1.1% from the Middle East. Among women, most hospitalizations (58.8%) were due to obstetrical-gynecological procedures or diseases, including assistance with delivery (27.1%), and pregnancy complications (18.7%), followed by psycho-social disturbances (5.9%), malignancies (5.1%), gastrointestinal diseases (4.7%), and voluntary pregnancy interruption (4.4%). Among men, the most frequent causes of admissions were related to trauma (15.9%), followed by gastroenteric disorders (12%), heart-vascular diseases (8.9%), psycho-social disorders (8.4%), respiratory (7.1%), kidney (6.1%), liver (5.2%), and metabolic (4

Sedentary behaviour is widely associated with deleterious health outcomes that in modern medicine have similar connotations to smoking tobacco and alcohol misuse. The integration of e-portfolio, e-logbook, British National Formulary (BNF) and encrypted emails has made smartphones a necessity for trainees. Smartphones also have the ability to record the amount of exercise taken, which allows activity at work to be monitored. The aim of this study to compare the activity of the same group of dental core trainees when they worked within a large multisite teaching hospital and a smaller district general hospital, to find out if supplementary activity was needed outside work. Data were collected from smartphones. To ensure continuity, data were collected only from those who had calibrated iPhones (n=10). At the teaching hospital six of the trainees walked over 10 000 steps a day while working (mean (SD) 10 004 (639)). At the district hospital none of the trainees walked 10 000 steps. The mean (SD) number of steps completed by all trainees was 6265 (119). Walking at work provides the full quota of recommended daily exercise most of the time for those working in the teaching hospital, but additional exercise is occasionally required. While working at the district hospital they walk less, meaning that they should try to increase their activity outside work. Trainees working in the teaching hospital walk significantly more steps than in the district hospital. Copyright © 2016 The British Association of Oral and Maxillofacial Surgeons.

One hundred years after its birth, general relativity has become a highly successful physical theory in the sense that it has passed a large number of experimental and observational tests and finds extensive application to a wide variety of cosmic phenomena. It remains an active area of research as new tests are on the way, epitomized by the exciting prospect of detecting gravitational waves from merging black holes. General relativity is the essential foundation of the standard model of cosmology and underlies our description of the black holes and neutron stars that are ultimately responsible for the most powerful and dramatic cosmic sources. Its interface with physics on the smallest and largest scales will continue to provide fertile areas of investigation in its next century.

Reformulation of the symmetries of first-order general relativity

2017-10-01

We report a new internal gauge symmetry of the n-dimensional Palatini action with cosmological term (n>3 ) that is the generalization of three-dimensional local translations. This symmetry is obtained through the direct application of the converse of Noether’s second theorem on the theory under consideration. We show that diffeomorphisms can be expressed as linear combinations of it and local Lorentz transformations with field-dependent parameters up to terms involving the variational derivatives of the action. As a result, the new internal symmetry together with local Lorentz transformations can be adopted as the fundamental gauge symmetries of general relativity. Although their gauge algebra is open in general, it allows us to recover, without resorting to the equations of motion, the very well-known Lie algebra satisfied by translations and Lorentz transformations in three dimensions. We also report the analog of the new gauge symmetry for the Holst action with cosmological term, finding that it explicitly depends on the Immirzi parameter. The same result concerning its relation to diffeomorphisms and the open character of the gauge algebra also hold in this case. Finally, we consider the non-minimal coupling of a scalar field to gravity in n dimensions and establish that the new gauge symmetry is affected by this matter field. Our results indicate that general relativity in dimension greater than three can be thought of as a gauge theory.

Peer-supported review of teaching: an evaluation.

Thampy, Harish; Bourke, Michael; Naran, Prasheena

Peer-supported review (also called peer observation) of teaching is a commonly implemented method of ascertaining teaching quality that supplements student feedback. A large variety of scheme formats with rather differing purposes are described in the literature. They range from purely formative, developmental formats that facilitate a tutor's reflection of their own teaching to reaffirm strengths and identify potential areas for development through to faculty- or institution-driven summative quality assurance-based schemes. Much of the current literature in this field focuses within general higher education and on the development of rating scales, checklists or observation tools to help guide the process. This study reports findings from a qualitative evaluation of a purely formative peer-supported review of teaching scheme that was implemented for general practice clinical tutors at our medical school and describes tutors' attitudes and perceived benefits and challenges when undergoing observation.

Cultural diversity and patient teaching.

PubMed

Price, J L; Cordell, B

Cultural diversity challenges health care providers to facilitate bridging cross-cultural gaps with clients. It is through providing culturally relevant care that health care practitioners truly serve the needs of all clients in our diverse society. A theory of Cultural Care Diversity and Universality offers a framework for building linkages of clinical knowledge to cultural care. A four-step approach to providing culturally sensitive patient teaching is described: (1) health care providers should assess their own cultural beliefs and be aware of general ethnic, regional, and religious beliefs and practices in their area; (2) develop a teaching plan; (3) implement the plan; (4) evaluate the success of the teaching-learning process and make alterations based on evaluation. When providers assess clients' beliefs and practices and incorporate them into the teaching plan design, teaching becomes more relevant and clients become more successful at learning.

High levels of stigma towards patients with substance use disorder (SUD) have been found in health professionals and medical students. To assess the capability of residents in general practice to diagnose SUD correctly; to assess their stigmatization of patients with SUD and to assess the correlation between both variables. We hypothesized a negative correlation. In 2014, we conducted a cross-sectional survey among French residents in general practice, using a self-administered questionnaire. First, a clinical case of SUD (tramadol) was presented, to assess the diagnosis and retained diagnostic criteria. A second clinical vignette was presented (intravenous heroin user) to assess stigmatization with the Attitudes to Mental Illness Questionnaire (AMIQ). Its score ranges from -10 (negative attitude) to +10 (positive attitude). AMIQ scores of residents who diagnosed SUD correctly versus incorrectly, and who had received at least six hours versus less than six hours of teaching on this topic, were compared using Student's t-test. Of 1284 solicited residents, 303 participated (23.6%), 249 residents diagnosed SUD correctly (82.2%). The mean AMIQ score was -3.91 (SD 2.4) without significant difference regarding the correct diagnosis of SUD; but with a significant difference between residents who had received training in SUD for at least six hours versus residents less trained (AMIQ scores -3.76 (SD 2.46) versus -4.50 (SD 2.27), p = .0354). Residents in general practice had a good capacity to diagnose SUD correctly but on average expressed negative attitudes toward people with SUD. More SUD teaching seems to help in reducing stigmatizing attitudes.

Generalized Kramers-Kronig relations in nonlinear optical- and THz-spectroscopy

Peiponen, K.-E.; Saarinen, J. J.

2009-05-01

Kramers-Kronig (K-K) relations have constituted one of the principal tools in the optical spectroscopy for the assessment of the optical properties of media from measured spectra. The underlying principle for the existence of the K-K relations is causality. Thanks to the K-K relations we have achieved a better understanding of both macroscopic and microscopic properties of media. Recently, various kinds of modified K-K relations have been presented in the literature. Such relations have been applied, e.g. to the nonlinear optical properties of polymers. A typical advantage of these generalized K-K relations is that the measured data do not need to be manipulated as in the case of the traditional K-K relations. Hence, the accuracy of the inverted data on linear or nonlinear optical properties of media becomes higher. A novel way to utilize generalized K-K relations is related to the measurement and correction of terahertz spectra in the time-domain reflection spectroscopy. Terahertz spectroscopy is nowadays one of the most rapidly developing fields in modern physics with applications being related to, e.g. security at the airports or inspection of pharmaceutical tablets. While recording THz spectra it is also possible to perform a chemical mapping of species. Therefore, correctness of the spectrum is of crucial importance for the identification of different species. This is possible by the generalized K-K relations. In this review paper we consider advances of K-K relations both in nonlinear optical and THz spectroscopy.

The study aim was to explore the nature of intraoperative education and its interaction with the environment where surgical education occurs. Video and audio recording captured teaching interactions between colorectal surgeons and general surgery residents during laparoscopic segmental colectomies. Cases and collected data were analyzed for teaching behaviors and workflow disruptions. Flow disruptions (FDs) are considered deviations from natural case progression. Across 10 cases (20.4 operative hours), attendings spent 11.2 hours (54.7%) teaching, using directing (M = 250.1), and confirming (M = 236.1) most. FDs occurred 410 times, accounting for 4.4 hours of case time (21.57%). Teaching occurred with FD events for 2.4 hours (22.2%), whereas 77.8% of teaching happened outside FD occurrence. Teaching methods shifted from active to passive during FD events to compensate for patient safety. Understanding how FDs impact operative learning will inform faculty development in managing interruptions and improve its integration into resident education. Copyright © 2016.

Teaching is an important skill. Academic physicians teach on a daily basis, and nearly all physicians occasionally teach colleagues and patients. There are generally few opportunities for medical students to learn teaching skills. We developed a novel "near-peer" teaching program in which fourth-year students cotaught first-year students. Eighteen fourth-year students enrolled in our institution's primary senior radiology elective learned the basics of ultrasound through a series of lectures and hands-on scanning sessions. Each fourth-year student, paired with a radiology resident or attending, then cotaught a first-year anatomy small group session. After instruction, voluntary surveys were administered to assess the perceived value of the "near-peer" teaching experience. Seventeen of 18 (94%) and 104 of 120 (87%) administered surveys were returned by fourth- and first-year students, respectively. Sixteen (94%) and 99 (95%) of the fourth- and first-year students reported they "enjoyed" or "really enjoyed" the near-peer teaching experience. Fourteen (82%) of the fourth years perceived improvement in their teaching skills and an increase in their knowledge. Only 8 (47%) of the fourth years thought they were "helpful" or "very helpful," though 92 (88%) of the first years identified their fourth-year co-instructors as "helpful" or "very helpful." We piloted a novel "near-peer" program. Both senior and freshman students enjoyed the experience, and fourth years thought the session was educational for them as well. Although most fourth years did not judge themselves as helpful, first-year students overwhelmingly considered them a useful addition to the session. Copyright © 2013 AUR. Published by Elsevier Inc.

This descriptive study was undertaken as part of a clinical improvement effort by the ASPAN Research and Education Committees to evaluate adult patients' perception of and satisfaction with the ASPAN Preoperative Patient Teaching videotape on general, regional, and minimum alveolar concentration (MAC)/conscious sedation anesthesia. Research findings on the use of videotapes for preoperative education are mixed. Some studies have reported that the use of videotapes increases knowledge and decreases anxiety, whereas other studies have shown a minimal effect on knowledge and anxiety. A convenience sample of 96 adult patients was chosen from those who were scheduled for surgeries with the above anesthesia techniques in 11 US hospitals and/or surgical centers within 4 ASPAN regional boundaries. Patients viewed the videotape the day(s) before surgery and then completed ASPAN's Preoperative Anesthesia Patient Teaching Questionnaire to measure patient perception and satisfaction. Sixty percent of the patients were women, and 50% had a college degree or higher. The average age of the patients was 51 (+/-17.2). Overall satisfaction scores had a potential range of 10 to 40, with higher scores indicating greater satisfaction. The mean satisfaction score for this study was 35 (+/-6.6). No significant relationships were found between satisfaction with the videotape and age, gender, or educational level. Patients were asked to rank each of 4 teaching methods. Among the choices of individualized instruction, written materials, Internet-based instruction, and videotape, the videotape method was ranked as most preferred. The information obtained from this study will be used to modify and improve the content of the patient education videotape produced by ASPAN.

Nutrition education: a questionnaire for assessment and teaching

PubMed Central

Makowske, Mary; Feinman, Richard D

2005-01-01

It is generally recognized that there is a need for improved teaching of nutrition in medical schools and for increased education of the general population. A questionnaire, derived in part from a study of physician knowledge, was administered to first year medical students in order to assess their knowledge of various aspects of nutrition and metabolism, and as a teaching tool to transmit information about the subject. The performance of first year students was consistent with a generally educated population but there were surprising deficits in some fundamental areas of nutrition. Results of the questionnaire are informative about student knowledge, and immediate reinforcement from a questionnaire may provide a useful teaching tool. In addition, some of the subject matter can serve as a springboard for discussion of critical issues in nutrition such as obesity and markers for cardiovascular disease. A major barrier to improved teaching of nutrition is the lack of agreement on some of these critical issues and there are apparent inconsistencies in recommendations of government and health agencies. It seems reasonable that improved teaching should address the lack of knowledge of nutrition, rather than knowledge of official guidelines. Student awareness of factual information should be the primary goal. PMID:15649324

This research examines the relative importance that cancer-related and non-cancer illness factors play in generating general health worries and/or cancer-related worries. The analysis also examines how these in turn impact anxiety and depression among older adult, long-term cancer survivors. Data from a longitudinal study of 245 older-adult (age 60+ years), long-term survivors (5 or more years after diagnosis) of breast, prostate, and colorectal cancer are examined to identify the measurement properties and structure of general health and cancer-related health worries. Based on that measurement analysis, structural equation models (SEM) are used to estimate the relative importance of cancer-related and other illness predictors on cancer-related worry and general health worry and how these two forms of worry affect both anxiety (POMS) and depression (CES-D). The results from the exploratory and confirmatory factor analysis of health worries identify two relatively independent measures of health worry, one of general health worry and a second of cancer-related worries that includes fears of recurrence, new cancers, and follow-up testing. SEM analyses identified the importance of current cancer-related symptoms and comorbidities on cancer-related worry. It also documents the primacy of non-cancer symptoms and general health worry as predictors of anxiety and depression among older survivors. The fact that cancer-related symptoms continue to be associated with cancer-related worries years after diagnosis speaks to the significance of these continuing sequelae. While the findings suggest the relative independence of cancer-related worries and general health worries, both are correlated with anxiety and depression. This may be particularly problematic as survivors age and symptoms related to new health problems increase, while cancer-related symptoms persist. Copyright © 2015 John Wiley & Sons, Ltd.

What Is Feminist Pedagogy? Useful Ideas for Teaching Chemistry

NASA Astrophysics Data System (ADS)

Hurt Middlecamp, Catherine; Subramaniam, Banu

1999-04-01

In our experience, scientists are likely to be newcomers to the scholarship that has arisen from the field of women's studies. This paper will examine one such area of scholarship, feminist pedagogy, and relate it to the teaching and learning of chemistry. More correctly, one should refer to feminist pedagogies, as this scholarship is evolving and is a topic for continual debate. Generally speaking, feminist pedagogies share a number of themes: a focus on women/gender, authority, position, empowerment, voice, and non-neutrality. Each of these themes is described and then applied to the chemistry classroom. Examples include using technology to give students a voice, using same-sex groupings, instituting a class board of directors, examining textbook questions, and asking new or different questions as you teach. Although feminist pedagogy aims to make science classrooms and laboratories more hospitable to women, it can inform our teaching practices and benefit all our students.

Conditions for excellence in teaching in medical education: The Frankfurt Model to ensure quality in teaching and learning.

Giesler, Marianne; Karsten, Gudrun; Ochsendorf, Falk; Breckwoldt, Jan

2017-01-01

Background: There is general consensus that the organizational and administrative aspects of academic study programs exert an important influence on teaching and learning. Despite this, no comprehensive framework currently exists to describe the conditions that affect the quality of teaching and learning in medical education. The aim of this paper is to systematically and comprehensively identify these factors to offer academic administrators and decision makers interested in improving teaching a theory-based and, to an extent, empirically founded framework on the basis of which improvements in teaching quality can be identified and implemented. Method: Primarily, the issue was addressed by combining a theory-driven deductive approach with an experience based, "best evidence" one during the course of two workshops held by the GMA Committee on Personnel and Organizational Development in Academic Teaching (POiL) in Munich (2013) and Frankfurt (2014). Two models describing the conditions relevant to teaching and learning (Euler/Hahn and Rindermann) were critically appraised and synthesized into a new third model. Practical examples of teaching strategies that promote or hinder learning were compiled and added to the categories of this model and, to the extent possible, supported with empirical evidence. Based on this, a checklist with recommendations for optimizing general academic conditions was formulated. Results: The Frankfurt Model of conditions to ensure Quality in Teaching and Learning covers six categories: organizational structure/medical school culture, regulatory frameworks, curricular requirements, time constraints, material and personnel resources, and qualification of teaching staff. These categories have been supplemented by the interests, motives and abilities of the actual teachers and students in this particular setting. The categories of this model provide the structure for a checklist in which recommendations for optimizing teaching are given

Canonical quantization of general relativity in discrete space-times.

PubMed

Gambini, Rodolfo; Pullin, Jorge

2003-01-17

It has long been recognized that lattice gauge theory formulations, when applied to general relativity, conflict with the invariance of the theory under diffeomorphisms. We analyze discrete lattice general relativity and develop a canonical formalism that allows one to treat constrained theories in Lorentzian signature space-times. The presence of the lattice introduces a "dynamical gauge" fixing that makes the quantization of the theories conceptually clear, albeit computationally involved. The problem of a consistent algebra of constraints is automatically solved in our approach. The approach works successfully in other field theories as well, including topological theories. A simple cosmological application exhibits quantum elimination of the singularity at the big bang.

Retention and recruitment of part time clinical adjunct faculty members in dental education is becoming increasingly difficult as dental schools come to rely on this workforce for their increased involvement in clinical education. Contributing factors include full time faculty shortage, aging workforce, practice and student debt, practice and family commitments, and financial compensation. This study attempts to ascertain barriers to teaching so appropriate strategies can be formulated to address this issue. In the spring of 2016 an email survey was sent to current and former adjunct faculty members to ascertain demographics and retention and recruitment strategies. Descriptive analyses were completed for all variables in the sample. Twenty nine of forty six subjects responded to the survey with a response rate of 63%. Subjects over the age of sixty comprised 55% with only 17% being under the age of forty five. Overall family and practice commitments along with compensation were the primary barriers to teaching part time. For new dentists, student loan debt was the primary barrier to teaching. Travel to teach was also a barrier as 70% of respondents drove 200 miles or less to the dental school. The study demonstrated that the aging part time work force is a great concern and new part time clinical adjunct faculty members must be recruited. Barriers to recruitment and retention of faculty must be considered and addressed to sustain this teaching model.

The double pulsar system PSR J0737-3039A/B is unique in that both neutron stars are detectable as radio pulsars. They are also known to have much higher mean orbital velocities and accelerations than those of other binary pulsars. The system is therefore a good candidate for testing Einstein's theory of general relativity and alternative theories of gravity in the strong-field regime. We report on precision timing observations taken over the 2.5 years since its discovery and present four independent strong-field tests of general relativity. These tests use the theory-independent mass ratio of the two stars. By measuring relativistic corrections to the Keplerian description of the orbital motion, we find that the "post-Keplerian" parameter s agrees with the value predicted by general relativity within an uncertainty of 0.05%, the most precise test yet obtained. We also show that the transverse velocity of the system's center of mass is extremely small. Combined with the system's location near the Sun, this result suggests that future tests of gravitational theories with the double pulsar will supersede the best current solar system tests. It also implies that the second-born pulsar may not have formed through the core collapse of a helium star, as is usually assumed.

OBJECTIVE To develop a system for measuring the teaching effort of medical school faculty and to implement a payment system that is based on it. DESIGN An interventional study with outcomes measured before and after the intervention. SETTING A department of internal medicine with a university hospital and an affiliated Veterans Administration hospital. INTERVENTION We assigned a value in teaching units to each teaching activity in proportion to the time expended by the faculty and the intensity of their effort. We then calculated total teaching units for each faculty member in the Division of General Internal Medicine and for combined faculty effort in each subspecialty division in the Department of Medicine. After determining the dollar value for a teaching unit, we distributed discretionary teaching dollars to each faculty member in the Division of General Internal Medicine and to each subspecialty division according to total teaching units. MEASUREMENTS AND MAIN RESULTS The distribution of discretionary teaching dollars was determined. In the year after the intervention, there was a substantial redistribution of discretionary teaching dollars among divisions. Compared with an increase in total discretionary dollars of 11.4%, the change in allocation for individual divisions ranged from an increase of 78.2% to a decrease of −28.5%. Further changes in the second year after the intervention were modest. The distribution of teaching units among divisions was similar to the distribution of questions across subspecialties on the American College of Physicians In-Training Examination (r = .67) and the American Board of Internal Medicine Certifying Examination (r = .88). CONCLUSIONS It is possible to measure the value of teaching effort by medical school faculty and to distribute discretionary teaching funds among divisions according to the value of teaching effort. When this intervention was used at our institution, there were substantial changes in the amounts

Numerical Hydrodynamics and Magnetohydrodynamics in General Relativity.

PubMed

Font, José A

2008-01-01

This article presents a comprehensive overview of numerical hydrodynamics and magneto-hydrodynamics (MHD) in general relativity. Some significant additions have been incorporated with respect to the previous two versions of this review (2000, 2003), most notably the coverage of general-relativistic MHD, a field in which remarkable activity and progress has occurred in the last few years. Correspondingly, the discussion of astrophysical simulations in general-relativistic hydrodynamics is enlarged to account for recent relevant advances, while those dealing with general-relativistic MHD are amply covered in this review for the first time. The basic outline of this article is nevertheless similar to its earlier versions, save for the addition of MHD-related issues throughout. Hence, different formulations of both the hydrodynamics and MHD equations are presented, with special mention of conservative and hyperbolic formulations well adapted to advanced numerical methods. A large sample of numerical approaches for solving such hyperbolic systems of equations is discussed, paying particular attention to solution procedures based on schemes exploiting the characteristic structure of the equations through linearized Riemann solvers. As previously stated, a comprehensive summary of astrophysical simulations in strong gravitational fields is also presented. These are detailed in three basic sections, namely gravitational collapse, black-hole accretion, and neutron-star evolutions; despite the boundaries, these sections may (and in fact do) overlap throughout the discussion. The material contained in these sections highlights the numerical challenges of various representative simulations. It also follows, to some extent, the chronological development of the field, concerning advances in the formulation of the gravitational field, hydrodynamics and MHD equations and the numerical methodology designed to solve them. To keep the length of this article reasonable, an effort has

Liu, Jun-Tong; Wang, Qing-Wen; Li, Lei

2017-08-01

In this paper, we first define a generalized ( f, g)-skew information |I_{ ρ }^{(f, g)} |(A) and two related quantity |J_{ ρ }^{(f, g)} |(A) and |U_{ ρ }^{(f, g)} |(A) for any non-Hermitian Hilbert-Schmidt operator A and a density operator ρ on a Hilbert space H and discuss some properties of them. And then, we obtain the following uncertainty relation in terms of |U_{ ρ }^{(f, g)} |(A): |U_{ ρ}^{(f, g)}|(A)|U_{ ρ}^{(f, g)}|(B)≥ β_{(f, g)}|Tr( f(ρ)g(ρ)[A, B]0)|2, which is a generalization of a known uncertainty relation in Ko and Yoo (J.

Nonmetricity formulation of general relativity and its scalar-tensor extension

NASA Astrophysics Data System (ADS)

Järv, Laur; Rünkla, Mihkel; Saal, Margus; Vilson, Ott

2018-06-01

Einstein's celebrated theory of gravitation can be presented in three forms: general relativity, teleparallel gravity, and the rarely considered before symmetric teleparallel gravity. Extending the latter, we introduce a new class of theories where a scalar field is coupled nonminimally to nonmetricity Q , which here encodes the gravitational effects like curvature R in general relativity or torsion T in teleparallel gravity. We point out the similarities and differences with analogous scalar-curvature and scalar-torsion theories by discussing the field equations, role of connection, conformal transformations, relation to f (Q ) theory, and cosmology. The equations for a spatially flat universe coincide with those of teleparallel dark energy, thus allowing us to explain accelerating expansion.

Sustaining High Quality Teaching and Evidence-based Curricula: Follow-up Assessment of Teachers in the REDI Project

PubMed Central

Bierman, Karen L; DeRousie, Rebecca M. Sanford; Heinrichs, Brenda; Domitrovich, Celene E.; Greenberg, Mark T.; Gill, Sukhdeep

2013-01-01

Recent research has validated the power of evidence-based preschool interventions to improve teaching quality and promote child school readiness when implemented in the context of research trials. However, very rarely are follow-up assessments conducted with teachers in order to evaluate the maintenance of improved teaching quality or sustained use of evidence-based curriculum components after the intervention trial. In the current study, we collected follow-up assessments of teachers one year after their involvement in the REDI research trial to evaluate the extent to which intervention teachers continued to implement the REDI curriculum components with high-quality, and to explore possible pre-intervention predictors of sustained implementation. In addition, we conducted classroom observations to determine whether general improvements in the teaching quality of intervention teachers (relative to control group teachers) were sustained. Results indicated sustained high-quality implementation of some curriculum components (the PATHS curriculum), but decreased implementation of other components (the language-literacy components). Sustained intervention effects were evident on most aspects of general teaching quality targeted by the intervention. Implications for practice and policy are discussed. PMID:24204101

Tests of general relativity from gravitational wave observations of binary black holes

NASA Astrophysics Data System (ADS)

Del Pozzo, Walter

2017-01-01

Gravitational waves emitted during the coalescence of compact binary systems carry a wealth of information about the merging objects, the remnant object as well as their interaction with space-time. The description of the dynamics of such systems is based on solutions of the theory of general relativity. For any given physical configuration of masses, spins and orbital motion, general relativity predicts the dynamical evolution of the binary system as well as the corresponding gravitational wave signal. During the coalescence of extremely compact objects such as binary black holes, the typical curvature and velocity at play are such that, from the observation of the gravitational wave signal, we can access the most extreme dynamical regimes of gravity. In such conditions, we can test our understanding of gravity by looking for potential departures between the solutions of general relativity and the actual dynamics of space-time. The LIGO observations GW150914 and GW151226 provided wonderful testing grounds for general relativity in the, up to now unaccessible, strong-field dynamical regime of gravity. During my talk, I will review and discuss several of the tests that have been devised to detect violations of the predictions of general relativity from the observation of gravitational waves from coalescing binary systems. The discussion will be based on the results of the analysis of GW150914 and GW151226. Finally, I will conclude by discussing some of the future prospects of extending the current state-of-the-art methodologies to further aspects of general relativity.

Spacecraft Tests of General Relativity

NASA Technical Reports Server (NTRS)

Anderson, John D.

1997-01-01

Current spacecraft tests of general relativity depend on coherent radio tracking referred to atomic frequency standards at the ground stations. This paper addresses the possibility of improved tests using essentially the current system, but with the added possibility of a space-borne atomic clock. Outside of the obvious measurement of the gravitational frequency shift of the spacecraft clock, a successor to the suborbital flight of a Scout D rocket in 1976 (GP-A Project), other metric tests would benefit most directly by a possible improved sensitivity for the reduced coherent data. For purposes of illustration, two possible missions are discussed. The first is a highly eccentric Earth orbiter, and the second a solar-conjunction experiment to measure the Shapiro time delay using coherent Doppler data instead of the conventional ranging modulation.

The distinctiveness and effectiveness of science teaching in the Malaysian `Smart school'

NASA Astrophysics Data System (ADS)

Tek Ong, Eng; Ruthven, Kenneth

2010-04-01

A recent reform initiative in the Malaysian educational system has sought to develop 'Smart schools', intended to better prepare students for adult life in a developing economy and to increase the flow of young people prepared for scientific and technological careers. The study reported in this paper examined lower-secondary science teaching, comparing two Smart schools officially judged to be successfully implementing the reform, with two neighbouring mainstream schools. Through analysis of classroom observation, supported by teacher interview and student report, the distinctive features of science teaching in the Smart schools were found to be use of ICT-based resources and of student-centred approaches, often intertwined to provide extended support for learning; accompanied by a near absence of the note giving and copying prevalent in the mainstream schools. Through analysis of measures of student attitude to science, science process skills and general science attainment, science teaching in Smart schools was found to be relatively effective overall. However, while the positive attitude effect was general, both academic effects were much weaker amongst students who had been of lower attainment on entry to secondary school.

Dimensions and profiles of the generalized health-related self-concept.

PubMed

Wiesmann, Ulrich; Niehörster, Gabriele; Hannich, Hans-Joachim; Hartmann, Ute

2008-11-01

We explore the significance of health as a potentially self-relevant category from the perspective of dynamic self-concept theory. Our intention was to describe the dimensional structure of the generalized health-related self-concept, to identify particular prototypes of health-related self-definition, and to see if these prototypes would differ with respect to appraisals of health behaviour and subjective health. We conducted a cross-sectional questionnaire study involving 545 college students (23.3% male) at the mean age of 22 years. The self-administered questionnaire assessed a relevant spectrum of health-related cognitions denoting their generalized declarative knowledge about their health (the generalized health-related self-concept). Additionally, participants rated their multiple health behaviour, their perceived health, and their anticipated vulnerability. A principal components analysis of the health-related cognitions revealed the following five dimensions: health-protective dispositions, health-protective motivation, vulnerability, health-risky habits, and external, avoidant motivation. A two-step cluster analysis of the five components identified six profiles of health-related self-concept: careless/carefree, omnipotents, risk-takers, mentally affected, reluctant-avoidant, and medically fragile. These prototypes could be successfully reclassified (97.6%). The six profiles differed with respect to their health behaviour and subjective health appraisals. The dimensional structure represents both resources and deficits with respect to an individual's health-related self-concept. An individual's profile of these dimensions might correspond to a characteristic set of particular health needs and motivations. Successful health communications should follow a complementary strategy of affirming the self-concept.

New Area Law in General Relativity.

PubMed

Bousso, Raphael; Engelhardt, Netta

2015-08-21

We report a new area law in general relativity. A future holographic screen is a hypersurface foliated by marginally trapped surfaces. We show that their area increases monotonically along the foliation. Future holographic screens can easily be found in collapsing stars and near a big crunch. Past holographic screens exist in any expanding universe and obey a similar theorem, yielding the first rigorous area law in big bang cosmology. Unlike event horizons, these objects can be identified at finite time and without reference to an asymptotic boundary. The Bousso bound is not used, but it naturally suggests a thermodynamic interpretation of our result.

Trials of large group teaching in Malaysian private universities: a cross sectional study of teaching medicine and other disciplines

2011-01-01

Background This is a pilot cross sectional study using both quantitative and qualitative approach towards tutors teaching large classes in private universities in the Klang Valley (comprising Kuala Lumpur, its suburbs, adjoining towns in the State of Selangor) and the State of Negeri Sembilan, Malaysia. The general aim of this study is to determine the difficulties faced by tutors when teaching large group of students and to outline appropriate recommendations in overcoming them. Findings Thirty-two academics from six private universities from different faculties such as Medical Sciences, Business, Information Technology, and Engineering disciplines participated in this study. SPSS software was used to analyse the data. The results in general indicate that the conventional instructor-student approach has its shortcoming and requires changes. Interestingly, tutors from Medicine and IT less often faced difficulties and had positive experience in teaching large group of students. Conclusion However several suggestions were proposed to overcome these difficulties ranging from breaking into smaller classes, adopting innovative teaching, use of interactive learning methods incorporating interactive assessment and creative technology which enhanced students learning. Furthermore the study provides insights on the trials of large group teaching which are clearly identified to help tutors realise its impact on teaching. The suggestions to overcome these difficulties and to maximize student learning can serve as a guideline for tutors who face these challenges. PMID:21902839

2015-01-01

The purpose of this study was to examine the associations of two types of parenting practices -- general adaptive parenting and technology-related strategies – with youth screen time. It was hypothesized that technology-related parenting focused on behavioral control would relate directly to screen time and serve to link general parenting to screen time. Participants were 615 parents drawn from three community samples of families with children across three development stages: young childhood (3 – 7 yrs.; n = 210), middle childhood (8 – 12 yrs.; n = 200), and adolescents (13 – 17 yrs.; n = 205). Using structural equation modeling, general adaptive parenting was not related to child screen time but was positively related to technology-related parenting strategies for all three samples. For the young and, to some extent middle, childhood samples, but not for the adolescent sample, general adaptive parenting was positively linked to youth screen time through technology-related parenting strategies.

Generalized Dynamic Equations Related to Condensation and Freezing Processes

NASA Astrophysics Data System (ADS)

Wang, Xingrong; Huang, Yong

2018-01-01

The generalized thermodynamic equation related to condensation and freezing processes was derived by introducing the condensation and freezing probability function into the dynamic framework based on the statistical thermodynamic fluctuation theory. As a result, the physical mechanism of some weather phenomena covered by using δ(0,1) can in turn be studied and uncovered. From the generalized dynamic equations, the tendency equation of the generalized potential vorticity (GPV) is derived. From the discussion of tendency equation of GPV, in some very thin transitional areas, GPV is found nonconserved because of the introduction of the condensation and freezing probability function, even in frictionless and moist adiabatic air motion.

The purpose of this study was to compare morality judgments of American Catholics and the general public about lesbians and gay men adopting and teaching children. The general sample endorsed higher agreement that lesbians and gay men should be allowed to adopt and to teach children compared to the Catholic only sample. Older participants were less accepting than all other age groups, and there was an interaction effect between education and political ideology such that those with less education and with more politically conservative beliefs were generally less accepting of lesbians and gay men adopting and teaching children.

The facilitative effects of incidental teaching on preposition use by autistic children.

1985-01-01

In a comparison of incidental teaching and traditional training procedures, three language-delayed autistic children were taught expressive use of prepositions to describe the location of preferred edibles and toys. Traditional highly structured training and incidental teaching procedures were used in a classroom setting, and generalization was assessed during free-play sessions. Results clearly indicate that incidental teaching promoted greater generalization and more spontaneous use of prepositions. These findings have important implications for language programming and teacher training, suggesting that incidental teaching should be included as a standard component of language development curricula for autistic and other developmentally delayed children.

This pilot study explored the effectiveness of an online workshop provided to faculty teaching one course in a large online RN-to-baccalaureate nursing (BSN) program. This exploration helped to fill a gap in knowledge related to implementing best classroom teaching practices into distance education for online nursing students. Focus groups with purposeful sampling (three focus groups: two faculty focus groups with a total of 11 faculty and one student focus group with a total of six students) were used to assess the effectiveness of the workshop and faculty and student perceptions of the seven best classroom teaching practices. Themes derived from the faculty focus groups included reaffirmation, commitments from students, and opportunities for instructor improvement. Themes derived from the student focus group included engagement, availability, encouragement, and diverse learning. Online teaching recommendations, created from the emerged themes of the study, could be considered to improve teaching practices of online nurse educators. J Contin Educ Nurs. 2016;47(5):222-227.

Reddy, Linda A; Fabiano, Gregory A; Dudek, Christopher M; Hsu, Louis

2013-12-01

This investigation examined 317 general education kindergarten through fifth-grade teachers' use of instructional and behavioral management strategies as measured by the Classroom Strategy Scale (CSS)-Observer Form, a multidimensional tool for assessing classroom practices. The CSS generates frequency of strategy use and discrepancy scores reflecting the difference between recommended and actual frequencies of strategy use. Hierarchical linear models (HLMs) suggested that teachers' grade-level assignment was related to their frequency of using instructional and behavioral management strategies: Lower grade teachers utilized more clear 1 to 2 step commands, praise statements, and behavioral corrective feedback strategies than upper grade teachers, whereas upper grade teachers utilized more academic monitoring and feedback strategies, content/concept summaries, student focused learning and engagement, and student thinking strategies than lower grade teachers. Except for the use of praise statements, teachers' usage of instructional and behavioral management strategies was not found to be related to years of teaching experience or to the interaction of years of teaching experience and grade-level assignment. HLMs suggested that teachers' grade level was related to their discrepancy scores of some instructional and behavioral management strategies: Upper grade teachers had higher discrepancy scores in academic performance feedback, behavioral feedback, and praise than lower grade teachers. Teachers' discrepancy scores of instructional and behavioral management strategies were not found to be related to years of teaching experience or to the interaction of years of teaching experience and grade-level assignment. Implications of results for school psychology practice are outlined. © 2013.

General Relativity solutions in modified gravity

NASA Astrophysics Data System (ADS)

Motohashi, Hayato; Minamitsuji, Masato

2018-06-01

Recent gravitational wave observations of binary black hole mergers and a binary neutron star merger by LIGO and Virgo Collaborations associated with its optical counterpart constrain deviation from General Relativity (GR) both on strong-field regime and cosmological scales with high accuracy, and further strong constraints are expected by near-future observations. Thus, it is important to identify theories of modified gravity that intrinsically possess the same solutions as in GR among a huge number of theories. We clarify the three conditions for theories of modified gravity to allow GR solutions, i.e., solutions with the metric satisfying the Einstein equations in GR and the constant profile of the scalar fields. Our analysis is quite general, as it applies a wide class of single-/multi-field scalar-tensor theories of modified gravity in the presence of matter component, and any spacetime geometry including cosmological background as well as spacetime around black hole and neutron star, for the latter of which these conditions provide a necessary condition for no-hair theorem. The three conditions will be useful for further constraints on modified gravity theories as they classify general theories of modified gravity into three classes, each of which possesses i) unique GR solutions (i.e., no-hair cases), ii) only hairy solutions (except the cases that GR solutions are realized by cancellation between singular coupling functions in the Euler-Lagrange equations), and iii) both GR and hairy solutions, for the last of which one of the two solutions may be selected dynamically.

2015-02-01

Novel approaches for faculty development and assessment of procedural teaching skills are needed to improve the procedural education of trainees. The Objective Structured Teaching Exercise (OSTE) entails a simulated encounter in which faculty are observed teaching a standardized student and has been used to evaluate teaching skills. Use of an OSTE to assess the teaching of central venous catheterization has not been reported. The purpose of this study was to develop a procedural OSTE for subclavian central venous catheter (CVC) insertion and to determine specific aspects of procedural teaching associated with improved skills in novices. Critical care faculty/fellows taught a standardized student to insert a CVC in a simulator. We assessed the instructor's teaching skills using rating scales to generate a procedural teaching score. After this encounter, the instructor taught novice medical students to place CVCs in simulators. Novices then independently placed catheters in simulators and were evaluated by trained observers using a checklist. Generalized estimating equations were used to examine the correlation between specific teaching behaviors and the novices' skills in CVC placement. We recruited 10 participants to serve as teachers and 30 preclinical medical students to serve as novice learners. The overall mean procedural teaching score was 85.5 (±15.4). Improved student performance was directly related to the degree to which the teacher "provided positive feedback" (β = 1.53, SE = 0.44, P = 0.001), "offered learner suggestions for improvement" (β = 1.40, SE = 0.35, P < 0.001), and "demonstrated the procedure in a step-by-step manner" (β = 2.50, SE = 0.45, P < 0.001). There was no significant correlation between total scores and student skills (β = 0.06, SE = 0.46, P = 0.18). The OSTE is a standardized method to assess procedural teaching skills. Our findings suggest that specific aspects of procedural
