2006-05-01

Powerful political forces have been at play in building a mandate to change the schools. The latest, on-going manifestation is in the No Child Left Behind Act, but the mandate for change was being formulated in the early 1980s in the A Nation at Risk report. As physicists we may feel somewhat removed from such goings on, but our children attend school and their teachers come through our classrooms. Physics education research offers extensive, carefully collected data on the consequences of standard physics teaching. The data challenges conventional beliefs about physics learning. It is said that times of crisis represent both opportunity and danger. Because the mandates to change are up to the individual states, each of us in our own state has the opportunity to shift the focus in physics/science teaching toward something better. We also face the danger that existing physics/science teaching will be even more deeply entrenched than it already is.

Full Text Available Introduction: Self-directed learning is originated from adult education which has currently gained a special place in educational systems and is influenced by many variables such as teaching self-efficacy and self-directed learning. This research investigated the relationship of teachers’ teaching with academic self-efficacy and self-directed learning from English language students' perspectives. Methods: The study population comprised of all bachelor, master and Ph.D. English language students of Allameh Tabataba’i University (2014-2015 who had passed at least one semester. A total of 159 students were selected as study sample using Cochran formula and proportional stratified sampling. The data were collected through three standard questionnaires with confirmed validity and reliability. Data were analyzed by one-sample t-test, Pearson correlation and multiple regression. Results: With regard to teaching efficiency, content presentation, learning evaluation and class management skills were higher than average and lesson planning and control over content skills were at an average level. Also, all dimensions of academic self-efficacy and self-directed learning were significantly higher than average. The correlation between teaching efficiency and self-efficacy (r=0.367 and self-directed learning (r=0.571, and between self-efficacy and self-directed learning (r=0.523 was statistically significant (P<0.01. Moreover, a combination of teaching efficiency dimensions could predict different dimensions of self-efficacy and all components of self-directed learning. Furthermore, self-efficacy dimensions were good predictors of self-directed learning. Conclusion: Success in the realm of academia and organizational learning depends on the learners’ updated knowledge and skills and self-directed learning. Also, it seems teachers’ efficient teaching affects students’ academic self-efficacy, orienting them toward self-directed learning.

Sagendorf, Kenneth S.

The purposes of this research were to create an inventory of the research, teaching and service background experiences of and to document the time allocation and time spent on teaching by early-career college science faculty members. This project is presented as three distinct papers. Thirty early-career faculty in the science disciplines from sixteen different institutions in their first year of employment participated in this study. For the first two papers, a new survey was developed asking participants to choose which experiences they had acquired prior to taking their current faculty position and asking them to document their time allocation and time spent on teaching activities in an average work week. In addition, a third component documents the support early-career college faculty in the sciences are receiving from the perspective of faculty members and their respective department chairpersons and identifies areas of disagreement between these two different groups. Twenty early-career college science faculty and their respective department chairpersons completed a newly-designed survey regarding the support offered to new faculty. The survey addressed the areas of feedback on performance, clarity of tenure requirements, mentoring, support for teaching and scholarship and balancing faculty life. This dissertation presents the results from these surveys, accounting for different demographic variables such as science discipline, gender and institutional category.

2013-01-01

This study aimed to assess the effectiveness of a blended-teaching intervention using Internet-based tutorials coupled with traditional lectures in an introduction to research undergraduate nursing course. Effects of the intervention were compared with conventional, face-to-face classroom teaching on three outcomes: knowledge, satisfaction, and self-learning readiness. A two-group, randomized, controlled design was used, involving 112 participants. Descriptive statistics and analysis of covariance (ANCOVA) were performed. The teaching method was found to have no direct impact on knowledge acquisition, satisfaction, and self-learning readiness. However, motivation and teaching method had an interaction effect on knowledge acquisition by students. Among less motivated students, those in the intervention group performed better than those who received traditional training. These findings suggest that this blended-teaching method could better suit some students, depending on their degree of motivation and level of self-directed learning readiness.

Flexible Learning and Teaching: Looking Beyond the Binary of Full-time/Part-time Provision in South African Higher Education

Directory of Open Access Journals (Sweden)

Barbara M Jones

2015-06-01

Full Text Available This paper engages with literature on flexible learning and teaching in order to explore whether it may be possible, within the South African context, to have flexible learning and teaching provide a third way which goes beyond the current practice of full-time/part-time provision. This binary classification of students is a proxy for day-time/after-hours delivery.  The argument is made that effective, flexible learning and teaching requires a fundamental shift in thinking about learning and teaching in higher education that moves us beyond such binaries. The paper proposes that in order to ensure access and success for students, ‘common knowledge’ (Edwards, 2010 will need to be co-constructed which understands flexible learning and teaching in ways which will meet needs of a diversity of students, including working students. It will require ‘resourceful leadership’ (Edwards, 2014 within the university that recognises, enhances and gives purpose to the capability of colleagues at every level of the systems they lead. Also, it will require the building of ‘common knowledge’ between certain sectors of universities and particular workplaces.

Teaching and new technologies: change of time and teaching experience by the use of computer and internet

2017-05-01

Full Text Available This article aimed to answer how the use of computers and the Internet, directly and indirectly, has affected the time of teaching work and how these tool have determined the experience of teachers. Sources of research consisted of doctoral and master theses, as well as official documents that referring to these concepts and instruments. The survey instrument was developed as a form, using a software for the collection and analysis of data; for the assessment of the results we used the content analysis technique. The results show the relationship between time and experience under different cultural conventions that permeate the school, consolidating awareness under contradictions supported by the potential of new technologies in a condition of atrophying the experience to which the training process and the work of the teacher would tend to be reduced. The method is achieved from critical theory, especially the concepts of experience indicated by Adorno and Benjamin, ideology of technological rationality and industrial society, by Marcuse, and key concepts of dialectical materialism, such as alienated labor, commodity and machinery, from Marx.

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.

Strongly and weakly directed approaches to teaching multiple representation use in physics

Directory of Open Access Journals (Sweden)

Patrick B. Kohl

2007-06-01

Full Text Available Good use of multiple representations is considered key to learning physics, and so there is considerable motivation both to learn how students use multiple representations when solving problems and to learn how best to teach problem solving using multiple representations. In this study of two large-lecture algebra-based physics courses at the University of Colorado (CU and Rutgers, the State University of New Jersey, we address both issues. Students in each of the two courses solved five common electrostatics problems of varying difficulty, and we examine their solutions to clarify the relationship between multiple representation use and performance on problems involving free-body diagrams. We also compare our data across the courses, since the two physics-education-research-based courses take substantially different approaches to teaching the use of multiple representations. The course at Rutgers takes a strongly directed approach, emphasizing specific heuristics and problem-solving strategies. The course at CU takes a weakly directed approach, modeling good problem solving without teaching a specific strategy. We find that, in both courses, students make extensive use of multiple representations, and that this use (when both complete and correct is associated with significantly increased performance. Some minor differences in representation use exist, and are consistent with the types of instruction given. Most significant are the strong and broad similarities in the results, suggesting that either instructional approach or a combination thereof can be useful for helping students learn to use multiple representations for problem solving and concept development.

Cheng, Yu-Tsun; Liu, Deborah R; Wang, Vincent J

2017-03-01

Splinting is a multistep procedure that is seldom performed by primary care physicians. Just-in-time training (JITT) is an emerging teaching modality and can be an invaluable asset for infrequently performed procedures or in locations where teaching resources and trained professionals are limited. Our objective was to determine the utility of JITT for teaching medical students the short-arm (SA) volar splinting technique. This was a prospective randomized controlled pilot study. An instructional video on SA volar splinting was produced. Students viewed the video or had access to standard medical textbooks (control group) immediately before applying an SA volar splint. The students were assessed for the quality of the splint via a standard 6-point skills checklist. The times required for presplinting preparation and for completion of the splint were also measured. Just-in-time training group students scored higher on the splint checklist (mean [SD], 5.45 [1.06]; 95% confidence interval [CI], 4.99-5.92 vs mean [SD], 1.58 [1.12]; 95% CI, 1.04-2.12; P < 0.0001), had higher pass rates (73%; 95% CI, 53%-93% vs 0%; P < 0.0001), and required less time (minutes) for presplinting preparation (mean [SD], 7.86 [2.45]; 95% CI, 6.78-8.94 vs mean [SD], 9.89 [0.46]; 95% CI, 9.67-10.12; P < 0.0001) compared with the control group. No difference was seen in the time required to complete a splint, successful or not. In comparison with reading standard textbooks, watching a brief JITT instructional video before splinting yielded faster learning times combined with more successful procedural skills. The use of a JITT instructional video may have potential applications, including globally, as an alternative resource for teaching and disseminating procedural skills, such as SA volar splinting.

Conklin, M T; Simko, M D

1994-02-01

We explored the direct economic benefits of hospital dietetics departments sponsoring an internship for dietetics studies. Forty-five dietetics departments in US hospitals participated in a mail survey that involved comprehensive data collection procedures using three instruments, including activity logs recorded by 298 dietitians and interns. Direct benefits were defined as the net student labor provided to the department during routine and staff relief experiences that released professional labor for other work. Net student productivity during routine assignments was calculated by subtracting the time dietitians spent teaching during a typical work week from the amount of time dietetic interns spent performing professional services without direct supervision. Student productivity during staff relief rotations was calculated by multiplying the number of students assigned to this type of experience by the length of the rotation. While involved in routine learning experiences, dietetic interns provided a direct benefit. The difference between the time interns spent in independent, professional service in the departments and the time dietitians spent in activities designed specifically for teaching was a mean of 29 hours in favor of the students. All departments received a direct benefit from assigning dietetic interns to a staff relief rotation. The median number of weeks of student labor gained by the departments per year was 24. A paired t test was used to analyze the difference between the time dietitians devoted to teaching interns and the time students spent in independent, professional service in the departments. The difference was very highly significant (P impact of their supervised practice program on the sponsoring organization.

Background It is generally accepted that surgical training is associated with increased surgical duration. The purpose of this study was to determine the magnitude of this increase for common surgical procedures by comparing surgery duration in teaching and nonteaching hospitals. Methods This retrospective population-based cohort study included all adult residents of Ontario, Canada, who underwent 1 of 14 surgical procedures between 2002 and 2012. We used several linked administrative databases to identify the study cohort in addition to patient-, surgeon- and procedure-related variables. We determined surgery duration using anesthesiology billing records. Negative binomial regression was used to model the association between teaching versus nonteaching hospital status and surgery duration. Results Of the 713 573 surgical cases included in this study, 20.8% were performed in a teaching hospital. For each procedure, the mean surgery duration was significantly longer for teaching hospitals, with differences ranging from 5 to 62 minutes across individual procedures in unadjusted analyses (all p surgery duration, adjusting for patient-, surgeon- and procedure-related variables as well as the clustering of patients within surgeons and hospitals. Conclusion Our results show that a wide range of surgical procedures require significantly more time to perform in teaching than nonteaching hospitals. Given the magnitude of this difference, the impact of surgical training on health care costs and clinical outcomes should be a priority for future studies. PMID:27007088

Optimal teaching methods for disease recognition using probe-based confocal laser endomicroscopy (pCLE) have not been developed. Our aim was to compare in-class didactic teaching vs. self-directed teaching of Barrett's neoplasia diagnosis using pCLE. This randomized controlled trial was conducted at a tertiary academic center. Study participants with no prior pCLE experience were randomized to in-class didactic (group 1) or self-directed teaching groups (group 2). For group 1, an expert conducted a classroom teaching session using standardized educational material. Participants in group 2 were provided with the same material on an audio PowerPoint. After initial training, all participants graded an initial set of 20 pCLE videos and reviewed correct responses with the expert (group 1) or on audio PowerPoint (group 2). Finally, all participants completed interpretations of a further 40 videos. Eighteen trainees (8 medical students, 10 gastroenterology trainees) participated in the study. Overall diagnostic accuracy for neoplasia prediction by pCLE was 77 % (95 % confidence interval [CI] 74.0 % - 79.2 %); of predictions made with high confidence (53 %), the accuracy was 85 % (95 %CI 81.8 % - 87.8 %). The overall accuracy and interobserver agreement was significantly higher in group 1 than in group 2 for all predictions (80.4 % vs. 73 %; P = 0.005) and for high confidence predictions (90 % vs. 80 %; P didactic teaching enables significantly better recognition of the pCLE features of Barrett's esophagus than self-directed teaching. The in-class didactic group had a shorter learning curve and were able to achieve 90 % accuracy for their high confidence predictions. © Georg Thieme Verlag KG Stuttgart · New York.

Methods: This needs assessment was an observational study with a cross-sectional design. Online or printed questionnaires were used to assess the preferred format and content for this curriculum among MS, residents from most postgraduate medical training programs, and PD from Faculté de médecine de l’Université Laval. Results: The questionnaires were completed by 26 PD (response rate 72.2%, 146 residents (response rate 21.9% and 154 MS (response rate 15.7%. Among the list of potential subjects that could be included in the curriculum, Learning styles, Working with students in difficulty and Self-directed learning were scored high by both residents and PD. MS favored Learning styles, Teaching in the ambulatory care setting, Teaching health promotion and prevention, Teaching with time constraints and Direct supervision strategies. PD also favored Teaching conflict management and Teaching professionalism, however these were both among the residents’ lower scores. The preferred formats were One half-day, One day and Online learning for PD and One day, Two consecutive days and A few one-day sessions over several months for residents. Conclusion: The PD and MS perception of the optimal format and content for residents’ teaching-skills training showed some discrepancies when compared with residents’ preferences. Since PD are largely involved in curriculum development for their respective specialties and since MS are also well positioned to assess residents’ teaching performance, we suggest that PD, residents and MS should all be consulted locally before organizing any intervention for teaching curricula.

2016-07-01

Graduate medical trainees have a critical role in the teaching of other trainees. Improving their teaching requires an understanding of their attitudes towards teaching and their motivation to teach. Both have been incompletely explored in this population. We aimed to better understand graduate medical trainees' attitudes towards teaching and motivation to teach in the clinical setting in order to inform modifications to resident-as-teacher (RAT) programmes and enhance teaching practices. We applied Q methodology, an established sorting method, to identify and quantify the factors that have an impact on trainees' engagement in teaching. We invited house officers at our institution to rank-order 47 statements regarding their attitudes to and motivation for teaching. Respondents explained their Q-sort rankings in writing and completed a demographic questionnaire. By-person factor analysis yielded groups of individuals with similar attitudes. One hundred and seven trainees completed the Q-sort. We found three primary groups of attitudes towards teaching in the clinical setting: enthusiasm, reluctance and rewarded. Enthusiastic teachers are committed and make time to teach. Teaching increases their job satisfaction. Reluctant teachers have enthusiasm but are earlier in training and feel limited by clinical workload and unprepared. Rewarded teachers feel teaching is worthwhile and derive satisfaction from the rewards and recognition they receive for teaching. This improved understanding of common attitudes shared by groups of residents will help curriculum designers create RAT programmes to further reinforce and encourage attitudes that promote teaching as well as improve trainees' motivation to teach. Designing RAT programmes that acknowledge the attitudes to and motivations for teaching should help develop effective teachers to improve educational outcomes. Directed efforts to enhance motivation for reluctant teachers and encourage more positive attitudes in rewarded

Full Text Available Learning quality constitutes one of the main challenges faced by Higher Education, thus a student centered teaching and the development of educational innovations that use active methodologies have been promoted. This article aims to evaluate the impact of using Just-in-Time Teaching and Peer Instruction on the results of teaching a subject, of disciplinary character, in 17 students of a career on an initial teacher training belonging to Chile’s Council of Rectors. A pre and postest model was applied between August and December 2012. The analysis used descriptive techniques that allowed the characterization of the admission profile and inferentials to explain, statistically, the observed differences in the performance of the subjects. In terms of perception, a positive assessment of the relationship between students and the teacher in the classroom was observed, this stood out above the improvement in the handling of disciplinary content.

Full Text Available The study of fixed expressions contributes to a significant demand of L2/SL teaching, the lexicon acquisition. The binomial language/culture gained a clear shape in the context of L2/SL teaching, so as to require the teacher to reflect constantly on the topics that outline the linguistic and cultural identity of the target language. Based on the assumption that time and culture are inseparable, the PFL/PL2 (Portuguese as a Foreign/ Second Language teacher has to be prepared to address the Brazilian concept of time. Relying on the notion of time language (HALL, 1996, this study seeks to identify aspects of the Brazilian temporal language. As fixed expressions have different types, it is often difficult to maintain theoretical boundaries among them. Considering Silva's definition of proverb (1999:14-15, some Brazilian popular sayings concerning time were selected. It was found that popular wisdom has at least two types of expressions that refer to time: those related to the concepts of clock time and the ones linked to the concepts of event time (LEVINE, 1997. It is intended therefore that this study may assist the PFL/PL2 teacher in addressing this issue.

Full Text Available This study aims to discuss how teaching and learning activities were carried out by using Genre based Approach in teaching writing descriptive text at junior high school. This study was conducted in the classroom of VII-1. Therefore, the appropriate design was qualitative research design. The subject of the study was the English teacher. To collect data, the researcher used observation and interview. The finding of the study described that the teaching and learning activities that were carried out by the teacher fulfilled the basic competencies. The teacher carried out the opening teaching activities by greeting, asking the students’ preparation during the lesson, checking the student’s attendance list, and informing the learning objective. The teacher carried out the main teaching activities by informing about how to write a descriptive text, giving, and asking opinions, eliciting the students’ understanding, prompting and directing to do exercises. The teacher carried out the closing teaching activities by directing the student to continue at home and eliciting the students’ reflection of what they could learn at that time.

2015-01-01

The American Board of Internal Medicine (ABIM) exam's pass rate is considered a quality measure of a residency program, yet few interventions have shown benefit in reducing the failure rate. We developed a web-based Directed Reading (DR) program with an aim to increase medical knowledge and reduce ABIM exam failure rate. Internal medicine residents at our academic medical center with In-Training Examination (ITE) scores ≤ 35 th percentile from 2007 to 2013 were enrolled in DR. The program matches residents to reading assignments based on their own ITE-failed educational objectives and provides direct electronic feedback from their teaching physicians. ABIM exam pass rates were analyzed across various groups between 2002 and 2013 to examine the effect of the DR program on residents with ITE scores ≤ 35 percentile pre- (2002-2006) and post-intervention (2007-2013). A time commitment survey was also given to physicians and DR residents at the end of the study. Residents who never scored ≤ 35 percentile on ITE were the most likely to pass the ABIM exam on first attempt regardless of time period. For those who ever scored ≤ 35 percentile on ITE, 91.9% of residents who participated in DR passed the ABIM exam on first attempt vs 85.2% of their counterparts pre-intervention (p ITE were more likely to fail ABIM exam on first attempt, those who participated in the DR program were less likely to fail than the historical control counterparts. The web-based teaching method required little time commitment by faculty.

Radiology seminars using teaching kits

International Nuclear Information System (INIS)

Munro, T.G.

1989-01-01

Clinco-radiological seminars are an effective method of teaching medical students. However, in busy departments it is often difficult to provide enough radiologists for small group instruction. This can be facilitated by the use of prepared teaching kits. Each kit contains a set of duplicated films and a syllabus which gives a short clinical history for each patient and a series of questions to be used to direct the discussion. Each diagnostic problem is chosen to demonstrate core material. We have been using these teaching kits for organ system teaching in the preclerkship year. Teaching kits offer several advantages. They make it easier to recruit seminar leaders through efficient use of their time. The use of duplicated films and a syllabus ensures that all students cover the same material. The syllabus can be used to generate examination questions for reinforcement of important concepts. The kits are also available to students to review alone and can be readily updated as required

Teachers' approaches to teaching physics

Benjamin Franklin said, "Tell me, and I forget. Teach me, and I remember. Involve me, and I learn." He would not be surprised to learn that research in physics pedagogy has consistently shown that the traditional lecture is the least effective teaching method for teaching physics. We asked high school physics teachers which teaching activities they used in their classrooms. While almost all teachers still lecture sometimes, two-thirds use something other than lecture most of the time. The five most often-used activities are shown in the table below. In the January issue, we will look at the 2013 Nationwide Survey of High School Physics teachers. Susan White is Research Manager in the Statistical Research Center at the American Institute of Physics; she directs the Nationwide Survey of High School Physics Teachers.

A critical aspect of teacher education is gaining pedagogical content knowledge of how to teach science for conceptual understanding. Given the time limitations of college methods courses, it is difficult to touch on more than a fraction of the science topics potentially taught across grades K-8, particularly in the context of relevant pedagogies. This research and development work centers on constructing a formative assessment resource to help expose pre-service teachers to a greater number of science topics within teaching episodes using various modes of instruction. To this end, 100 problem-based, science pedagogy assessment items were developed via expert group discussions and pilot testing. Each item contains a classroom vignette followed by response choices carefully crafted to include four basic pedagogies (didactic direct, active direct, guided inquiry, and open inquiry). The brief but numerous items allow a substantial increase in the number of science topics that pre-service students may consider. The intention is that students and teachers will be able to share and discuss particular responses to individual items, or else record their responses to collections of items and thereby create a snapshot profile of their teaching orientations. Subsets of items were piloted with students in pre-service science methods courses, and the quantitative results of student responses were spread sufficiently to suggest that the items can be effective for their intended purpose.

Is direct measurement of time possible?

Science.gov (United States)

Reynolds, Thomas

2017-08-01

Is direct measurement of time possible? The answer to this question may depend upon how one understands time. Is time an essential constituent of physical reality? Or is what scientists are talking about when they use the symbol ‘t’ or the word ‘time’ an human cultural construct, as the Chief of the USA NIST Divisions of Time and Frequency and of Quantum Physics has suggested. Few aspects of physics do not reference activity to time, but many discussions within either view of time seem to use one same, largely traditional, language of time. Briefly considering the question of measurement, including from a formal measure-theoretic point of view, clarifies the situation.

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.

Surgical expertise demands technical and nontechnical skills. Traditionally, surgical trainees acquired these skills in the operating room; however, operative time for residents has decreased with duty hour restrictions. As in other professions, video analysis may help maximize the learning experience. To develop and evaluate a postoperative video-based coaching intervention for residents. In this mixed methods analysis, 10 senior (postgraduate year 4 and 5) residents were videorecorded operating with an attending surgeon at an academic tertiary care hospital. Each video formed the basis of a 1-hour one-on-one coaching session conducted by the operative attending; although a coaching framework was provided, participants determined the specific content collaboratively. Teaching points were identified in the operating room and the video-based coaching sessions; iterative inductive coding, followed by thematic analysis, was performed. Teaching points made in the operating room were compared with those in the video-based coaching sessions with respect to initiator, content, and teaching technique, adjusting for time. Among 10 cases, surgeons made more teaching points per unit time (63.0 vs 102.7 per hour) while coaching. Teaching in the video-based coaching sessions was more resident centered; attendings were more inquisitive about residents' learning needs (3.30 vs 0.28, P = .04), and residents took more initiative to direct their education (27% [198 of 729 teaching points] vs 17% [331 of 1977 teaching points], P based coaching is a novel and feasible modality for supplementing intraoperative learning. Objective evaluation demonstrates that video-based coaching may be particularly useful for teaching higher-level concepts, such as decision making, and for individualizing instruction and feedback to each resident.

In nursing education, the traditional lecture and direct demonstration teaching method cannot cultivate the various skills that nursing students need. How to choose a more scientific and rational teaching method is a common concern for nursing educators worldwide. To investigate the basis for selecting teaching methods among nursing teachers in mainland China, the factors affecting the selection of different teaching methods, and the application of different teaching methods in theoretical and skill-based nursing courses. Questionnaire survey. Seventy one nursing colleges from 28 provincial-level administrative regions in mainland China. Following the principle of voluntary informed consent, 262 nursing teachers were randomly selected through a nursing education network platform and a conference platform. The questionnaire contents included the basis for and the factors influencing the selection of nursing teaching methods, the participants' common teaching methods, and the teaching experience of the surveyed nursing teachers. The questionnaires were distributed through the network or conference platform, and the data were analyzed by SPSS 17.0 software. The surveyed nursing teachers selected teaching methods mainly based on the characteristics of the teaching content, the characteristics of the students, and their previous teaching experiences. The factors affecting the selection of teaching methods mainly included large class sizes, limited class time, and limited examination formats. The surveyed nursing teachers primarily used lectures to teach theory courses and the direct demonstration method to teach skills courses, and the application frequencies of these two teaching methods were significantly higher than those of other teaching methods (P=0.000). More attention should be paid to the selection of nursing teaching methods. Every teacher should strategically choose teaching methods before each lesson, and nursing education training focused on selecting

CLEAR PM: Teaching, Outreach, and Research Through Real-Time Particulate Measurements

Science.gov (United States)

DeCarlo, P. F.

2013-12-01

An understanding of particulate matter (also called aerosols) can be made through measurement. This measurement does not change in value if it is made in a teaching, research, or outreach environment. A grant from the Camille and Henry Dreyfus Foundation provided funding to construct an instrument suite composed of 1-4 second measurements that are displayed in real-time through a software interface. This display module is called CLEAR PM (Chemistry Lessons Enabling Aerosol Realizations through Particulate Measurement), and was conceived to apply across outreach activities, teaching activities, and research activities. The construction and software design of CLEAR PM was done as part of a special topics course for chemistry and engineering graduate students at Drexel University. Measurement principles of the different (research grade) instruments were taught as part of the course, with emphasis put on the fundamental measurements and their limitations, and an introduction to data acquisition software was also integral to the teaching component. As a final project of the course graduate students were required to create a 'teaching' module that illustrates a chemistry or physics concept and utilizes the measurements of CLEAR PM. These modules ranged from gas-phase ozone chemistry creating secondary organic aerosols, to the wavelength dependent absorption profiles of wood smoke versus propane soot. The teaching modules developed by the graduate students have been used in outreach activities sponsored by The Franklin Institute and the Clean Air Council in Philadelphia, where underrepresented groups often make up a large fraction of the audience. CLEAR PM is designed to give students and citizens a hands-on opportunity to see how we measure and understand the world around us. As mentioned previously, the instruments that are part of CLEAR PM are research grade instruments, and are actively being used in research projects in the DeCarlo lab at Drexel to study particulate

Direct output feedback control of discrete-time systems

International Nuclear Information System (INIS)

Lin, C.C.; Chung, L.L.; Lu, K.H.

1993-01-01

An optimal direct output feedback control algorithm is developed for discrete-time systems with the consideration of time delay in control force action. Optimal constant output feedback gains are obtained through variational process such that certain prescribed quadratic performance index is minimized. Discrete-time control forces are then calculated from the multiplication of output measurements by these pre-calculated feedback gains. According to the proposed algorithm, structural system is assured to remain stable even in the presence of time delay. The number of sensors and controllers may be very small as compared with the dimension of states. Numerical results show that direct velocity feedback control is more sensitive to time delay than state feedback but, is still quite effective in reducing the dynamic responses under earthquake excitation.

　　Language is not only part of culture, but also the carrier. The relationship between them decides the important role of culture teaching in language teaching. However, some problems still exist in college English teaching. For example, classroom English teaching time is not enough for culture teaching; English learners’native language thinking has negative transfer in the target language learning, etc.. In order to solve these problems, this paper tends to discuss whether English teaching should put an emphasis on Big-C Culture or Little-c Culture.

Palocaren, Jeeji; Pillai, Lekha S; Celine, T M

2016-01-01

The Medical Council of India (MCI) recommendations on medical education suggest a shift from didactic lectures to more interactive lectures. This study assessed the effectiveness of different pedagogical methods in biochemistry and the perceptions of students and teachers about the shift from didactic to interactive lectures. An interventional crossover study was done with the topic divided into three biochemical modules and one clinical module. The students were divided into two batches, one of which was given didactic and the other, interactive lectures. They were assessed immediately after the lecture and four months later. Anonymous feedback was obtained to gauge the students' perceptions regarding the mode of teaching. The teachers' feedback on the use of both pedagogical styles was also obtained. There was no significant difference between the performance of the two groups in either examination in three of the modules. However, there was a statistically significant difference between the two groups' performance in the module that had clinical applications, with students from the interactive lecture group performing better. All students preferred interactive classes, irrespective of the topic taught. The teachers indicated that, although at the outset the interactive lectures were difficult to manage, both in terms of content and time, these drawbacks could be overcome with time and practice. Interactive lectures are an effective teaching method in biochemistry, especially in topics involving clinical application.

Full Text Available A not entirely unusual position among teachers is that they believe that they must first establish a peaceful classroom before they can begin to teach the subject. This research, shows how a proficient mathematics teacher teaches his subject and thereby creates a quiet and focused classroom and exerts effective leadership, just by teaching mathematics. The researchers observed a male mathematics teacher for almost half a year, i.e. one semester. The results of research present several patterns that the researchers saw during the observations of his teaching. The teacher showed an interest in each student’s mathematical thinking and expressed explicitly how students were expected to learn mathematics. He also directed students’ attention to mathematics and established a culture where all solutions were important in the teaching process. In the teaching process, he used multiple representations to motivate students and a lot of supportive expressions that made them feel that they were able to learn mathematics. He worked patiently to establish structures, and there was almost no disruptive behaviour. Students simply did not have time to interfere because they were so engaged in learning mathematics.

Extensive field tests of four new introductory physics courses, in which the new models were compared with more traditional courses, have yielded many results. The most interesting of these are not directly related to how the new models fared, but instead to general features shared in common by many physics courses. The theme is simply that it is important to set concrete and well-defined goals, and to design every in- and out-of-class activity so that the students' time is devoted to achieving those goals.

Regan-Smith, Martha; Young, William W; Keller, Adam M

2002-07-01

Teaching and learning in the ambulatory setting have been described as inefficient, variable, and unpredictable. A model of ambulatory teaching that was piloted in three settings (1973-1981 in a university-affiliated outpatient clinic in Portland, Oregon, 1996-2000 in a community outpatient clinic, and 2000-2001 in an outpatient clinic serving Dartmouth Medical School's teaching hospital) that combines a system of education and a system of patient care is presented. Fully integrating learners into the office practice using creative scheduling, pre-rotation learning, and learner competence certification enabled the learners to provide care in roles traditionally fulfilled by physicians and nurses. Practice redesign made learners active members of the patient care team by involving them in such tasks as patient intake, histories and physicals, patient education, and monitoring of patient progress between visits. So that learners can be active members of the patient care team on the first day of clinic, pre-training is provided by the clerkship or residency so that they are able to competently provide care in the time available. To assure effective education, teaching and learning times are explicitly scheduled by parallel booking of patients for the learner and the preceptor at the same time. In the pilot settings this teaching model maintained or improved preceptor productivity and on-time efficiency compared with these outcomes of traditional scheduling. The time spent alone with patients, in direct observation by preceptors, and for scheduled case discussion was appreciated by learners. Increased satisfaction was enjoyed by learners, teachers, clinic staff, and patients. Barriers to implementation include too few examining rooms, inability to manipulate patient appointment schedules, and learners' not being present in a teaching clinic all the time.

One of the important objectives in teaching numerical methods for undergraduates’ students is to bring into the comprehension of numerical methods algorithms. Although, manual calculation is important in understanding the procedure, it is time consuming and prone to error. This is specifically the case when considering the iteration procedure used in many numerical methods. Currently, many commercial programs are useful in teaching numerical methods such as Matlab, Maple, and Mathematica. These are usually not user-friendly by the uninitiated. Excel spreadsheet offers an initial level of programming, which it can be used either in or off campus. The students will not be distracted with writing codes. It must be emphasized that general commercial software is required to be introduced later to more elaborated questions. This article aims to report on a teaching numerical methods strategy for undergraduates engineering programs. It is directed to students, lecturers and researchers in engineering field.

Faculty in the Division of Hospital Medicine provide most of the clinical teaching for learners at our institution. The majority of these faculty are Assistant Professors with limited formal instruction in clinical teaching. Previous Divisional strategies to improve clinical teaching ability included discussion of effective teaching behaviors, developing written expectations for teaching faculty, and instituting seminars on effective clinical teaching. Heretofore, the Division had not utilized a direct observation exercise. We developed a direct observation exercise to encourage discussion of teaching techniques and contemplation of change. Using a social learning model, we developed a peer-to-peer observation followed by a nonevaluative discussion. We created a tool for describing teaching behaviors in 5 domains that were similar to or different from the usual behavior of the observing peer: learner presentations, team leadership, bedside teaching, professionalism, and other. After the observation, the observing and observed faculty met to discuss observed teaching behaviors. Both faculty members discussed and then recorded any teaching behaviors that they planned to adopt or change. We implemented this intervention in a 22-member Academic Division of Hospital Medicine at a tertiary care medical center in the United States. A high proportion were junior faculty and graduates of our residency program. We reviewed records of 28 of 31 observations that were completed during the initial 9-month period of implementation and later surveyed faculty. The exercise resulted in planned changes in teaching behaviors that included instituting new methods to improve teaching team leadership, triaging of patients seen on rounds, faculty behaviors during oral presentations, giving real-time feedback, use of technology and humor, demonstrating physical examination findings, and modeling professional behaviors. Faculty later reported adoption of new teaching behaviors that were

Challenge: Clinical and research responsibilities often leave little or no time to plan thoughtful teaching encounters with trainees. This "Teaching & Learning Tips" series is designed to be an accessible guide for dermatologists who want to improve their teaching skills. It is comprised of 12 articles about how to enhance teaching in various settings informed by research about how people learn and expert-derived or data-driven best practices for teaching. The series begins with a review of principles to optimize learning in any setting, including cognitive load theory, active learning strategies, and the impact of motivation and emotion on learning. It transitions into a practical "how to" guide format for common teaching scenarios in dermatology, such as lecturing, case-based teaching, and teaching procedures, among others. Herein, we kickoff the series by unpacking assumptions about teaching and learning. What does it mean to teach and learn? © 2017 The International Society of Dermatology.

A tutorial introduction to transient electromagnetics, focusing on direct time-domain techniques, is presented. Physical, mathematical, numerical, and experimental aspects of time-domain methods, with emphasis on wire objects excited as antennas or scatters are examined. Numerous computed examples illustrate the characteristics of direct time-domain procedures, especially where they may offer advantages over procedures in the more familiar frequency domain. These advantages include greater solution efficiency for many types of problems, the ability to handle nonlinearities, improved physical insight and interpretability, availability of wide-band information from a single calculation, and the possibility of isolating interactions among various parts of an object using time-range gating

Full Text Available Universities are at a time of change. Their social, political and economic conditions are under challenge, while technological change challenges curriculum design and implementation, requiring reconsiderations of teaching and learning practices. In this context, and as part of the conference session on Higher education in 2014: threshold, watershed or business as usual?, I reviewed an approach I have been trialing to supporting early- and mid-career academics to navigate through this changing environment. This paper presents an illustrated essay on a human-scale approach to early- and mid-career mentoring through the establishment of small team-based research and writing projects. The essay provides examples of activities that, on the one hand, assist academics to develop the tools they need to navigate the new and evolving environment of higher education, while on the other hand directly addresses key pedagogical issues and provides new insight into teaching and learning in higher education.

Direct Characterization of Ultrafast Energy-Time Entangled Photon Pairs.

Science.gov (United States)

MacLean, Jean-Philippe W; Donohue, John M; Resch, Kevin J

2018-02-02

Energy-time entangled photons are critical in many quantum optical phenomena and have emerged as important elements in quantum information protocols. Entanglement in this degree of freedom often manifests itself on ultrafast time scales, making it very difficult to detect, whether one employs direct or interferometric techniques, as photon-counting detectors have insufficient time resolution. Here, we implement ultrafast photon counters based on nonlinear interactions and strong femtosecond laser pulses to probe energy-time entanglement in this important regime. Using this technique and single-photon spectrometers, we characterize all the spectral and temporal correlations of two entangled photons with femtosecond resolution. This enables the witnessing of energy-time entanglement using uncertainty relations and the direct observation of nonlocal dispersion cancellation on ultrafast time scales. These techniques are essential to understand and control the energy-time degree of freedom of light for ultrafast quantum optics.

Highlights: • Hilbert–Huang Transform are applied to modify real earthquake records. • Generate tri-directional time histories compatible with target spectra. • Both GRS and FRS are considered as target spectra. • Target spectra with multiple damping ratios are considered. - Abstract: This paper proposes two algorithms to generate spectrum-compatible time histories based on two approaches recommended by USNRC Standard Review Plan 3.7.1. Hilbert–Huang Transform technique is used to analyze frequency contents and amplitudes of seed motions. Through adjusting the frequency contents and amplitudes of seed motions, spectrum-compatible time histories are obtained. The first algorithm is to generate tri-directional time histories compatible with multi-damping target design spectra (ground response spectra or floor response spectra). The second algorithm is to generate tri-directional time histories compatible with single-damping target design spectra. Examples are presented to demonstrate versatility of these two proposed algorithms to generate spectra-compatible time histories.

Ready, set, teach! How to transform the clinical nurse expert into the part-time clinical nurse instructor.

Science.gov (United States)

Hewitt, Peggy; Lewallen, Lynne Porter

2010-09-01

Many schools of nursing are hiring part-time clinical instructors with little or no teaching experience. Although they contribute greatly to student nurses' clinical experience, many do not realize the commitment they are making when they accept such a position. If key issues are addressed before new part-time clinical instructors begin teaching, the transition could be made more smoothly. An in-depth orientation, awareness of the need for preparation for clinical rotations, and strategies to assist students in achieving course objectives can guide new instructors as they begin this venture. Preparing new part-time clinical instructors from the beginning will give them a more accurate picture of clinical education, increasing their recruitment and retention and providing students with quality learning experiences.

As distributed undergraduate and postgraduate medical education becomes more common, the challenges with the teaching and learning process also increase. To collaboratively engage front line teachers in improving teaching in a distributed medical program. We recently conducted a contest on teaching tips in a provincially distributed medical education program and received entries from faculty and resident teachers. Tips that are helpful for teaching around clinical cases at distributed teaching sites include: ask "what if" questions to maximize clinical teaching opportunities, try the 5-min short snapper, multitask to allow direct observation, create dedicated time for feedback, there are really no stupid questions, and work with heterogeneous group of learners. Tips that are helpful for multi-site classroom teaching include: promote teacher-learner connectivity, optimize the long distance working relationship, use the reality television show model to maximize retention and captivate learners, include less teaching content if possible, tell learners what you are teaching and make it relevant and turn on the technology tap to fill the knowledge gap. Overall, the above-mentioned tips offered by front line teachers can be helpful in distributed medical education.

de Blacam, Catherine; Tierney, Sean; Shelley, Odhran

2017-08-01

Surgical training requires exposure to clinical decision-making and operative experience in a supervised environment. It is recognised that learning ability is compromised when fatigued. The European Working Time Directive requires a decrease in working hours, but compliance reduces trainees' clinical exposure, which has profound implications for plastic surgery training. The aim of this study was to evaluate plastic surgery registrars' experience of an EWTD-compliant rota, and to examine its impact on patient care, education, and logbook activity. An electronic survey was distributed to plastic surgery registrars in a university teaching hospital. Registrars were asked to rate 31 items on a five-point Likert scale, including statements on patient care, clinical and operative duties, training, and quality-of-life. Interquartile deviations explored consensus among responses. Operative caseload was objectively evaluated using eLogbook data to compare activity at equal time points before and after implementation of the EWTD rota. Highest levels of consensus among respondents were found in positive statements addressing alertness and preparation for theatre, as well as time to read and study for exams. Registrars agreed that EWTD compliance improved their quality-of-life. However, it was felt that continuity of patient care was compromised by work hours restriction. Registrars were concerned about their operative experience. eLogbook data confirmed a fall-off in mean caseload of 31.8% compared to activity prior to EWTD rota implementation. While EWTD compliant rotas promote trainee quality-of-life and satisfaction with training, attention needs to be paid to optimising operative opportunities.

The use of real time ultrasound scanning as a teaching method of anatomy in an undergraduate sonography and medical imaging degree in an Australian university

International Nuclear Information System (INIS)

Bowman, A.; Lawson, C.; McKillup, S.

2016-01-01

Background: Real-time ultrasound scanning is increasing in popularity as a teaching tool for human anatomy because it is non-invasive, offers real-time 3-D anatomy and is cheaper than dissections. Aim: To assess real-time ultrasound scanning as a teaching method of human anatomy, and to determine what teaching methods medical imaging and sonography students consider effective for understanding human anatomy. Method: Surveys were distributed to two consecutive cohorts of first year medical imaging and medical sonography students at CQUniversity. Participation was voluntary. Comparisons among teaching methods were made using repeated measures ANOVA. Results: Real-time ultrasound scanning was the most preferred method of delivery for anatomy classes overall especially compared to computer programs, videos, 3-D radiological images and dissection. Specifically, students indicated that ultrasound scanning was the preferred method to encourage learning from experience (F 7,231  = 2.942, p = 0.006), to develop team skills (F 7,231  = 4.550, p < 0.006), to follow complex instructions (F 7,231  = 4.656 p < 0.001) and to appreciate anatomical variation (F 7,231  = 2.067, p = 0.048). Dissection was the least favoured teaching method. Conclusion: Real-time ultrasound scanning is a useful tool for teaching anatomy, and animal dissections are a poor substitute for the use of human cadavers. - Highlights: • Real-time ultrasound scanning is a valid teaching tool for human anatomy. • Real-time ultrasound is preferred by students compared to other teaching methods. • Dissection is the least favoured method to learn anatomy. • Ultrasound encourages learning from experience and develops team skills.

New ideas for teaching electrocardiogram interpretation and improving classroom teaching content.

Interpreting an electrocardiogram (ECG) is not only one of the most important parts of diagnostics but also one of the most difficult areas to teach. Owing to the abstract nature of the basic theoretical knowledge of the ECG, its scattered characteristics, and tedious and difficult-to-remember subject matter, teaching how to interpret ECGs is as difficult for teachers to teach as it is for students to learn. In order to enable medical students to master basic knowledge of ECG interpretation skills in a limited teaching time, we modified the content used for traditional ECG teaching and now propose a new ECG teaching method called the "graphics-sequence memory method." A prospective randomized controlled study was designed to measure the actual effectiveness of ECG learning by students. Two hundred students were randomly placed under a traditional teaching group and an innovative teaching group, with 100 participants in each group. The teachers in the traditional teaching group utilized the traditional teaching outline, whereas the teachers in the innovative teaching group received training in line with the proposed teaching method and syllabus. All the students took an examination in the final semester by analyzing 20 ECGs from real clinical cases and submitted their ECG reports. The average ECG reading time was 32 minutes for the traditional teaching group and 18 minutes for the innovative teaching group. The average ECG accuracy results were 43% for the traditional teaching group and 77% for the innovative teaching group. Learning to accurately interpret ECGs is an important skill in the cardiac discipline, but the ECG's mechanisms are intricate and the content is scattered. Textbooks tend to make the students feel confused owing to the restrictions of the length and the format of the syllabi, apart from many other limitations. The graphics-sequence memory method was found to be a useful method for ECG teaching.

Full Text Available Currently, the ‘time’ variable has taken on the function of instructional and pedagogical innovation catalyst, after representing-over the years-a symbol of democratisation, learning opportunity and instruction quality, able to incorporate themes such as school dropout, personalisation and vocation into learning. Spaced Learning is a teaching methodology useful to quickly seize information in long-term memory based on a particular arrangement of the lesson time that comprises three input sessions and two intervals. Herein we refer to a teachers’ training initiative on Spaced Learning within the programme ‘DocentiInFormAzione’ in the EDOC@WORK3.0 Project in Apulia region in 2015. The training experience aimed at increasing teachers’ competencies in the Spaced Learning method implemented in a context of collaborative reflection and reciprocal enrichment. The intent of the article is to show how a process of rooting of the same culture of innovation, which opens to the discovery (or rediscovery of effective teaching practices sustained by scientific evidences, can be successfully implemented and to understand how or whether this innovation- based on the particular organisation of instructional time-links learning awareness to learning outcomes.

HAS THE TIME COME TO CHANGE THE WAY WE TEACH COMMUNITY MEDICINE TO UNDERGRADUATE STUDENTS?

Full Text Available Why the need to change ? Substantial increase in the content of subject : The content of the subject has grown by at least 30 % from the time when I was an undergraduate student and we used to read the 7th edition of Preventive and Social Medicine by Park. At that time this book had only 686 pages (size of pages was at least 30 % less than now had only 16 chapters .The 21st edition of the same book has 868 pages and 23 chapters. This goes on to show that the content of subject has increased substantially. 12 weeks of clinical posting added : Medical Council of India has added 12 weeks of clinical posting to the teaching of Community Medicine similar to the postings in major clinical subjects, where in the students are available to us in small groups for approximately 3 hours everyday. In spite of the increase in subject content and the opportunity for small group teaching during postings, I personally feel that we have not been able to inspire students to learn Community Medicine with enthusiasm. Why the subject has not become much popular among under graduate students? Before going into the further details let us look at the following observations made by the WHO -SEARO expert group on “Improving the teaching of Public Health at undergraduate level in medical schools – suggested guidelines.” – Today most of the teaching in public health is carried out using didactic lectures within the ivory tower of an institution with limited exposure to the community .Public health education has to be an active process ,student centered , inquiry driven , evidence based and problem solving as well addressing the needs of the community .The role of the teacher should be to facilitate the student to acquire the competencies through field based experiential learning of public health competencies involving dedicated time for practice , receiving feedback and reflecting on its application in their future role as primary care doctors1.

2013-07-01

Despite limited preparation and knowledge base, surgical interns have important teaching responsibilities. Nevertheless, few faculty development programs are aimed at interns. Succinct teaching skill content was electronically distributed over time (spaced education) to interns in academic year 2010/2011. The interns in the previous year served as historic controls. Electronic surveys were distributed for program evaluation. Fifteen of 24 (62.5%) interns and 35 of 49 (71.4%) students responded to the surveys in academic year 2009/2010 and 16 of 27 (59.3%) interns and 38 of 52 (73%) students responded in academic year 2010/2011. Surveys showed improved attitudes toward teaching by interns as well as a higher estimation of interns' teaching skills as rated by students for those interns who received the spaced education program. Using spaced education to improve interns' teaching skills is a potentially powerful intervention that improves interns' enthusiasm for teaching and teaching effectiveness. The changes are mirrored in students' ratings of interns' teaching skills and interns' attitudes toward teaching. Copyright © 2013 Elsevier Inc. All rights reserved.

Perspectives on learning, learning to teach and teaching elementary science

Science.gov (United States)

Avraamidou, Lucy

The framework that characterizes this work is that of elementary teachers' learning and development. Specifically, the ways in which prospective and beginning teachers' develop pedagogical content knowledge for teaching science in light of current recommendations for reform emphasizing teaching and learning science as inquiry are explored. Within this theme, the focus is on three core areas: (a) the use of technology tools (i.e., web-based portfolios) in support of learning to teach science at the elementary level; (b) beginning teachers' specialized knowledge for giving priority to evidence in science teaching; and (c) the applications of perspectives associated with elementary teachers' learning to teach science in Cyprus, where I was born and raised. The first manuscript describes a study aimed at exploring the influence of web-based portfolios and a specific task in support of learning to teach science within the context of a Professional Development School program. The task required prospective teachers to articulate their personal philosophies about teaching and learning science in the form of claims, evidence and justifications in a web-based forum. The findings of this qualitative case study revealed the participants' developing understandings about learning and teaching science, which included emphasizing a student-centered approach, connecting physical engagement of children with conceptual aspects of learning, becoming attentive to what teachers can do to support children's learning, and focusing on teaching science as inquiry. The way the task was organized and the fact that the web-based forum provided the ability to keep multiple versions of their philosophies gave prospective teachers the advantage of examining how their philosophies were changing over time, which supported a continuous engagement in metacognition, self-reflection and self-evaluation. The purpose of the study reported in the second manuscript was to examine the nature of a first

Direct time delay feedback can make non-chaotic Chen circuit chaotic. The chaotic Chen circuit with direct time delay feedback possesses rich and complex dynamical behaviours. To reach a deep and clear understanding of the dynamics of such circuits described by delay differential equations, Hopf bifurcation in the circuit is analysed using the Hopf bifurcation theory and the central manifold theorem in this paper. Bifurcation points and bifurcation directions are derived in detail, which prove to be consistent with the previous bifurcation diagram. Numerical simulations and experimental results are given to verify the theoretical analysis. Hopf bifurcation analysis can explain and predict the periodical orbit (oscillation) in Chen circuit with direct time delay feedback. Bifurcation boundaries are derived using the Hopf bifurcation analysis, which will be helpful for determining the parameters in the stabilisation of the originally chaotic circuit

To review the compliance of the European Working Time Directive (EWTD) in different teaching hospitals across Europe and its consequences upon training. It is an observational, descriptive, cross-sectional study. The sample is constituted by the answers from trainees selected by the representatives of 29 European Network of Trainees in Ob/Gyn (ENTOG) member countries to a survey designed by ENTOG Executive. The survey content was based on a joint survey by the Royal College of Obstetricians and Gynaecologists (RCOG) and the Royal College for Paediatrics (RCP), carried out in 2008, but adapted for use on a European level. An answer rate of 75% was obtained. Only 5 countries out of 29 were compliant with EWTD two months before the compulsory adherence. Countries needed to introduce 1 to 4 changes to the system to make the rotas -compliant. Positive effect on work and private life balance was noticed in 87% from all responses. Trainees notice the need to further improve training programmes in order to have the same quality of training and continuous care of patients. Steps forward to implement EWTD are being made. Trainees should be involved with the introduction to optimize training conditions under the EWTD. Countries that still struggle to introduce the directive may learn from countries that already are compliant. It is suggested to organize a survey on senior society level to gain additional information to further investigate the effects on training quality and patient care.

The influence of structural and institutional change on teaching and culture in clinical settings: an exploratory study.

Science.gov (United States)

Goldie, J; Dowie, A; Goldie, Anne; Cotton, Phil; Morrison, Jill

2015-02-01

Learning in clinical settings is a function of activity, context and culture. Glasgow University's Medical School has undergone significant curricular change in recent years. This has coincided with change to National Health Service consultants' contracts, the introduction of the European Working Time Directive and the Modernising Medical Careers training initiative. We wished to explore teachers' and students' perspectives on the effects of change on our clinical teachers' capacity for teaching and on medical culture. A qualitative approach using individual interviews with educational supervisors and focus groups with senior clinical students was used. Data were analysed using a "framework" technique. Curricular change has led to shorter clinical attachments in the senior clinical rotation, which combined with more centralised teaching have had adverse effects on both formal and informal teaching during attachments. Consultants' NHS contract changes the implementation of the European Working Time Directive and changes to postgraduate training have adversely affected consultants' teaching capacity, which has had a detrimental effect on their relationships with students. Medical culture has also changed as a result of these and other societal influences. The apprenticeship model was still felt to be relevant in clinical settings. This has to be balanced against the need for systematic teaching. Structural and institutional change affects learning. Faculty needs to be aware of the socio-historical context of their institutions.

A method for creating teaching movie clips using screen recording software: usefulness of teaching movies as self-learning tools for medical students

I wanted to describe a method to create teaching movies with using screen recordings, and I wanted to see if self-learning movies are useful for medical students. Teaching movies were created by direct recording of the screen activity and voice narration during the interpretation of educational cases; we used a PACS system and screen recording software for the recording (CamStudio, Rendersoft, U.S.A.). The usefulness of teaching movies for seft-learning of abdominal CT anatomy was evacuated by the medical students. Creating teaching movie clips with using screen recording software was simple and easy. Survey responses were collected from 43 medical students. The contents of teaching movie was adequately understandable (52%) and useful for learning (47%). Only 23% students agreed the these movies helped motivated them to learn. Teaching movies were more useful than still photographs of the teaching image files. The students wanted teaching movies on the cross-sectional CT anatomy of different body regions (82%) and for understanding the radiological interpretation of various diseases (42%). Creating teaching movie by direct screen recording of a radiologist's interpretation process is easy and simple. The teaching video clips reveal a radiologist's interpretation process or the explanation of teaching cases with his/her own voice narration, and it is an effective self-learning tool for medical students and residents.

Owing to the abstract nature of the basic theoretical knowledge of the ECG, its scattered characteristics, and tedious and difficult-to-remember subject matter, teaching how to interpret ECGs is as difficult for teachers to teach as it is for students to learn. In order to enable medical students to master basic knowledge of ECG interpretation skills in a limited teaching time, we modified the content used for traditional ECG teaching and now propose a new ECG teaching method called the “graphics-sequence memory method.” Methods: A prospective randomized controlled study was designed to measure the actual effectiveness of ECG learning by students. Two hundred students were randomly placed under a traditional teaching group and an innovative teaching group, with 100 participants in each group. The teachers in the traditional teaching group utilized the traditional teaching outline, whereas the teachers in the innovative teaching group received training in line with the proposed teaching method and syllabus. All the students took an examination in the final semester by analyzing 20 ECGs from real clinical cases and submitted their ECG reports. Results: The average ECG reading time was 32 minutes for the traditional teaching group and 18 minutes for the innovative teaching group. The average ECG accuracy results were 43% for the traditional teaching group and 77% for the innovative teaching

The introduction of direct electron detectors enabled the structural biology revolution of cryogenic electron microscopy. Direct electron detectors are now expected to have a similarly dramatic impact on time-resolved MeV electron microscopy, particularly by enabling both spatial and temporal jitter correction. Here we report on the commissioning of a direct electron detector for time-resolved MeV electron microscopy. The direct electron detector demonstrated MeV single electron sensitivity and is capable of recording megapixel images at 180 Hz. The detector has a 15-bit dynamic range, better than 30-μmμm spatial resolution and less than 20 analogue-to-digital converter count RMS pixel noise. The unique capabilities of the direct electron detector and the data analysis required to take advantage of these capabilities are presented. The technical challenges associated with generating and processing large amounts of data are also discussed.

Circadian-Time Sickness: Time-of-Day Cue-Conflicts Directly Affect Health.

Science.gov (United States)

van Ee, Raymond; Van de Cruys, Sander; Schlangen, Luc J M; Vlaskamp, Björn N S

2016-11-01

A daily rhythm that is not in synchrony with the environmental light-dark cycle (as in jetlag and shift work) is known to affect mood and health through an as yet unresolved neural mechanism. Here, we combine Bayesian probabilistic 'cue-conflict' theory with known physiology of the biological clock of the brain, entailing the insight that, for a functional pacemaker, it is sufficient to have two interacting units (reflecting environmental and internal time-of-day cues), without the need for an extra homuncular directing unit. Unnatural light-dark cycles cause a time-of-day cue-conflict that is reflected by a desynchronization between the ventral (environmental) and dorsal (internal) pacemaking signals of the pacemaker. We argue that this desynchronization, in-and-of-itself, produces health issues that we designate as 'circadian-time sickness', analogous to 'motion sickness'. Copyright © 2016 Elsevier Ltd.

Teaching with Moodle in Soil Science

Science.gov (United States)

Roca, Núria

2014-05-01

Soil is a 3-dimensional body with properties that reflect the impact of climate, vegetation, fauna, man and topography on the soil's parent material over a variable time span. Therefore, soil is integral to many ecological and social systems and it holds potential solutions for many of the world's economic and scientific problems as climate change or scarcity of food and water. The teaching of Soil Science, as a natural science in its own right, requires principles that reflect the unique features and behaviour of soil and the practices of soil scientists. It could be argued that a unique set of teaching practices applies to Soil Science; however specific teaching practices are scarce in literature. The present work was triggered by the need to develop new techniques of teaching to speed up the learning process and to experiment with new methods of teaching. For such, it is necessary to adopt virtual learning environment to new learning requirements regarding Soil Science. This paper proposes a set of e-teaching techniques (as questionnaires, chats as well as forums) introduced in Moodle virtual learning Environment in order to increase student motivation and interest in Soil Science. Such technologies can be used to: a)Increase the amount of time a teacher allots for student reflection after asking a question and before a student responds (wait-time). This practice increases the quantity and quality of students' answers. The students give longer responses, students give more evidence for their ideas and conclusions, students speculate and hypothesize more and more students participated in responding. Furthermore, students ask more questions and talk more to other students. b)Improve active learning, an essential paradigm in education. In contrast to learning-before-doing, we propose to focus on learning-in-doing, a model where learners are increasingly involved in the authentic practices of communities through learning conversations and activities involving expert

Best teaching practices in anatomy education: A critical review.

Science.gov (United States)

Estai, Mohamed; Bunt, Stuart

2016-11-01

In this report we review the range of teaching resources and strategies used in anatomy education with the aim of coming up with suggestions about the best teaching practices in this area. There is much debate about suitable methods of delivering anatomical knowledge. Competent clinicians, particularly surgeons, need a deep understanding of anatomy for safe clinical procedures. However, because students have had very limited exposure to anatomy during clinical training, there is a concern that medical students are ill-prepared in anatomy when entering clerkships and residency programs. Therefore, developing effective modalities for teaching anatomy is essential to safe medical practice. Cadaver-based instruction has survived as the main instructional tool for hundreds of years, however, there are differing views on whether full cadaver dissection is still appropriate for a modern undergraduate training. The limitations on curricular time, trained anatomy faculty and resources for gross anatomy courses in integrated or/and system-based curricula, have led many medical schools to abandon costly and time-consuming dissection-based instruction in favour of alternative methods of instruction including prosection, medical imaging, living anatomy and multimedia resources. To date, no single teaching tool has been found to meet curriculum requirements. The best way to teach modern anatomy is by combining multiple pedagogical resources to complement one another, students appear to learn more effectively when multimodal and system-based approaches are integrated. Our review suggests that certain professions would have more benefit from certain educational methods or strategies than others. Full body dissection would be best reserved for medical students, especially those with surgical career intentions, while teaching based on prosections and plastination is more suitable for dental, pharmacy and allied health science students. There is a need to direct future research

Less-structured time in children's daily lives predicts self-directed executive functioning.

Barker, Jane E; Semenov, Andrei D; Michaelson, Laura; Provan, Lindsay S; Snyder, Hannah R; Munakata, Yuko

2014-01-01

Executive functions (EFs) in childhood predict important life outcomes. Thus, there is great interest in attempts to improve EFs early in life. Many interventions are led by trained adults, including structured training activities in the lab, and less-structured activities implemented in schools. Such programs have yielded gains in children's externally-driven executive functioning, where they are instructed on what goal-directed actions to carry out and when. However, it is less clear how children's experiences relate to their development of self-directed executive functioning, where they must determine on their own what goal-directed actions to carry out and when. We hypothesized that time spent in less-structured activities would give children opportunities to practice self-directed executive functioning, and lead to benefits. To investigate this possibility, we collected information from parents about their 6-7 year-old children's daily, annual, and typical schedules. We categorized children's activities as "structured" or "less-structured" based on categorization schemes from prior studies on child leisure time use. We assessed children's self-directed executive functioning using a well-established verbal fluency task, in which children generate members of a category and can decide on their own when to switch from one subcategory to another. The more time that children spent in less-structured activities, the better their self-directed executive functioning. The opposite was true of structured activities, which predicted poorer self-directed executive functioning. These relationships were robust (holding across increasingly strict classifications of structured and less-structured time) and specific (time use did not predict externally-driven executive functioning). We discuss implications, caveats, and ways in which potential interpretations can be distinguished in future work, to advance an understanding of this fundamental aspect of growing up.

Teaching science in museums

Science.gov (United States)

Tran, Lynn Uyen

Museums are free-choice, non-threatening, non-evaluative learning and teaching environments. They enable learners to revisit contents, authentic objects, and experiences at their own leisure as they continually build an understanding and appreciation of the concepts. Schools in America have used museums as resources to supplement their curriculum since the 19 th century. Field trip research is predominantly from the teachers' and students' perspectives, and draws attention to the importance for classroom teachers and students to prepare prior to field trips, have tasks, goals, and objectives during their time at the museum, and follow up afterwards. Meanwhile, museum educators' contributions to field trip experiences have been scantily addressed. These educators develop and implement programs intended to help students' explore science concepts and make sense of their experiences, and despite their limited time with students, studies show they can be memorable. First, field trips are a break in the usual routine, and thus have curiosity and attention attracting power. Second, classroom science teaching literature suggests teachers' teaching knowledge and goals can affect their behaviors, and in turn influence student learning. Third, classroom teachers are novices at planning and implementing field trip planners, and museum educators can share this responsibility. But little is reported on how the educators teach, what guides their instruction, how classroom teachers use these lessons, and what is gained from these lessons. This study investigates two of these inquiries. The following research questions guided this investigation. (1) How do educators teaching one-hour, one-time lessons in museums adapt their instruction to the students that they teach? (2) How do time limitations affect instruction? (3) How does perceived variability in entering student knowledge affect instruction? Four educators from two museums took part in this participant observation study to

Teaching methotrexate self-injection with a web-based video maintains patient care while reducing healthcare resources: a pilot study.

The aim of the study was to compare standard nurse-led methotrexate self-injection patient education to a web-based methotrexate self-injection education video in conjunction with standard teaching on patient self-confidence for self-injection, as well as patient satisfaction, patient knowledge and teaching time. Consecutive rheumatology patients seen for methotrexate self-injection education were enrolled. Prior to education, patient self-confidence for self-injection, age, gender and education were recorded. Patients were randomized 1:1 to standard teaching or the intervention: a 12-min methotrexate self-injection education video followed by further in-person nurse education. Patients recorded their post-education confidence for self-injection, satisfaction with the teaching process and answered four specific questions testing knowledge on methotrexate self-injection. The time spent providing direct education to the patient was recorded. Twenty-nine patients participated in this study: 15 had standard (C) teaching and 14 were in the intervention group (I). Average age, gender and education level were similar in both groups. Both groups were satisfied with the quality of teaching. There was no difference in pre-confidence (C = 5.5/10 vs. I = 4.7/10, p = 0.44) or post-confidence (C = 8.8, I = 8.8, p = 0.93) between the groups. There was a trend toward improved patient knowledge in the video group versus the standard group (C = 4.7/6, I = 5.5/6, p = 0.15). Nurse teaching time was less in the video group (C = 60 min, I = 44 min, p = 0.012), with men requiring longer education time than women across all groups. An education video may be a good supplement to standard in-person nurse teaching for methotrexate self-injection. It equals the standard teaching practise with regard to patient satisfaction, confidence and knowledge while decreasing teaching time by 25 %.

Background In an integrated method of education, medical students are introduced to radiology in their preclinical years. However, no study has been conducted in Pakistan to demonstrate an academic framework of medical radiology education at an undergraduate level. Therefore, we aimed to document and compare the current level of teaching duties, teaching methodologies, and teaching rewards among radiologists and residents in private and public teaching hospitals in Karachi, Pakistan. Methods A survey was conducted among 121 radiologists and residents in two private and two public teaching hospitals in Karachi, Pakistan. Radiologists who were nationally registered with the Pakistan Medical and Dental Council either part-time or full-time were included. Radiology residents and fellows who were nationally registered with the Pakistan Medical and Dental Council were also included. Self-administered questionnaires addressing teaching duties, methods, and rewards were collected from 95 participants. Results The overall response rate was 78.51% (95/121). All of the radiologists were involved in teaching residents and medical students, but only 36% reported formal training in teaching skills. Although most of the respondents (76%) agreed that medical students appeared enthusiastic about learning radiology, the time spent on teaching medical students was less than five hours per week annually (82%). Only 37% of the respondents preferred dedicated clerkships over distributed clerkships (41%). The most common preferred teaching methodology overall was one-on-one interaction. Tutorials, teaching rounds, and problem-based learning sessions were less favored by radiologists than by residents. Teaching via radiology films (86%) was the most frequent mode of instruction. Salary (59%) was the most commonly cited teaching reward. The majority of respondents (88%) were not satisfied with their current level of teaching rewards. Conclusion All radiologists and residents working in an

Full Text Available Investigative microbiology on protists in a basic teaching laboratory environment is limited by student skill level, ease of microbial culture and manipulation, instrumentation, and time. The flow cytometer is gaining use as a mainstream instrument in research and clinical laboratories, but has had minimal application in teaching laboratories. Although the cost of a flow cytometer is currently prohibitive for many microbiology teaching environments and the number of trained instructors and teaching materials is limited, in many ways the flow cytometer is an ideal instrument for teaching basic microbiology. We report here on a laboratory module to study phagocytosis in Tetrahymena sp. using flow cytometry in a basic microbiology teaching laboratory. Students and instructors found the flow cytometry data analysis program, Paint-A-GatePRO-TM, to be very intuitive and easy to learn within a short period of time. Assessment of student learning about Tetrahymena sp., phagocytosis, flow cytometry, and investigative microbiology using an inquiry-based format demonstrated an overall positive response from students.

Samsonov, A. A.; Sibeck, D. G.; Dmitrieva, N. P.; Semenov, V. S.; Slivka, K. Yu.; Å afránkova, J.; Němeček, Z.

2018-05-01

Observed delays in the ground response to solar wind directional discontinuities have been explained as the result of larger than expected magnetosheath propagation times. Recently, Samsonov et al. (2017, https://doi.org/10.1002/2017GL075020) showed that the typical time for a southward interplanetary magnetic field (IMF) turning to propagate across the magnetosheath is 14 min. Here by using a combination of magnetohydrodynamic simulations, spacecraft observations, and analytic calculations, we study the dependence of the propagation time on solar wind parameters and near-magnetopause cutoff speed. Increases in the solar wind speed result in greater magnetosheath plasma flow velocities, decreases in the magnetosheath thickness and, as a result, decreases in the propagation time. Increases in the IMF strength result in increases in the magnetosheath thickness and increases in the propagation time. Both magnetohydrodynamic simulations and observations suggest that propagation times are slightly smaller for northward IMF turnings. Magnetosheath flow deceleration must be taken into account when predicting the arrival times of solar wind structures at the dayside magnetopause.

European Working Time Directive: implications for surgical training.

LENUS (Irish Health Repository)

Donohoe, C L

2010-02-01

The forthcoming implementation of the European Working Time Directive (EWTD) for non-consultant hospital doctors (NCHDs) poses a number of challenges in the areas of patient care, training, service provision and quality of life for workers. Surgery, as a craft-based speciality, will face a greater impact on training of future surgeons as operating time could be lost to service provision. The EWTD acts a stimulus for reform of current working practices and re-configuration of services. It will necessitate transformation of the way in which surgeons are trained, if current standards are to be maintained.

2018-01-01

The increasing prevalence of mobile devices in clinical settings has the potential to improve both patient care and education. The benefits are particularly promising in the context of family-centered rounds in inpatient pediatric settings. We aimed to increase mobile device usage by inpatient rounding teams by 50% in 6 months. We hoped to demonstrate that use of mobile devices would improve access to patient care and educational information and to determine if use would improve efficiency and perceptions of clinical teaching. We designed a mixed-methods study involving pre- and post-implementation surveys to residents, families, and faculty as well as direct observations of family-centered rounds. We conducted rapid cycles of continual quality improvement by using the Plan-Do-Study-Act framework involving 3 interventions. Pre-intervention, the mobile computing cart was used for resident education on average 3.3 times per rounding session. After cycle 3, teaching through the use of mobile devices increased by ∼79% to 5.9 times per rounding session. On the basis of survey data, we determined there was a statistically significant increase in residents' perception of feeling prepared for rounds, receiving teaching on clinical care, and ability to teach families. Additionally, average time spent per patient on rounds decreased after implementation of mobile devices. Integration of mobile devices into a pediatric hospital medicine teaching service can facilitate patient care and perception of resident teaching by extending the utility of electronic medical records in care decisions and by improving access to knowledge resources.

Dettmer, S; Weidemann, J; Fischer, V; Wacker, F K

2015-04-01

To survey integrative teaching in radiology at German universities. A questionnaire about radiological education was sent electronically to all 37 chairpersons of university radiology departments in Germany. The questions included the course type, teaching methods, concept, perception, and advantages and disadvantages of integrative teaching. Statistical analysis was performed with nonparametric statistics and chi-square test. The survey was considered representative with a return rate of 68 %. Integrative teaching is established at 4/5 of all departments. Integrative teaching is well accepted with an acceptance rate that is significantly higher in so-called "Modellstudiengängen" [model courses of study] (100 %) compared to conventional courses of study (72 %). The advantages of integrative teaching include linking of content (92 %) and preparation for interdisciplinary work (76 %). The disadvantages include high effort (75 %) and time (67 %) for organization. Furthermore, there is a risk that basic radiological facts and knowledge cannot be conveyed and that the visibility of radiology as an independent discipline is lost. Conventional radiological teaching has a similarly high acceptance (84 %) compared to integrative courses (76 %). Integrative teaching has a high acceptance among chairpersons in radiology in Germany despite the greater effort. A good interdisciplinary collaboration is essential for integrative teaching and at the same time this can be conveyed to the students. However, the visibility of radiology as a discipline and the possibility to cover basic radiological content must be ensured. Therefore, both conventional courses and integrative teaching seems reasonable, especially in cross-disciplinary subjects such as radiology. Both integrative teaching and conventional radiological teaching are highly accepted. The advantages include the linking of multidisciplinary content and the preparation for interdisciplinary cooperation

In this study, we developed a centrifugal direct recombinase polymerase amplification (direct-RPA) microdevice for multiplex and real-time identification of food poisoning bacteria contaminated milk samples. The microdevice was designed to contain identical triplicate functional units and each unit has four reaction chambers, thereby making it possible to perform twelve direct-RPA reactions simultaneously. The integrated microdevice consisted of two layers: RPA reagents were injected in the top layer, while spiked milk samples with food poisoning bacteria were loaded into sample reservoirs in the bottom layer. For multiplex bacterial detection, the target gene-specific primers and probes were dried in each reaction chamber. The introduced samples and reagents could be equally aliquoted and dispensed into each reaction chamber by centrifugal force, and then the multiplex direct-RPA reaction was executed. The target genes of bacteria spiked in milk could be amplified at 39 °C without a DNA extraction step by using the direct-RPA cocktails, which were a combination of a direct PCR buffer and RPA enzymes. As the target gene amplification proceeded, the increased fluorescence signals coming from the reaction chambers were recorded in real-time at an interval of 2 min. The entire process, including the sample distribution, the direct-RPA reaction, and the real-time analysis, was accomplished with a custom-made portable genetic analyzer and a miniaturized optical detector. Monoplex, duplex, and triplex food poisoning bacteria (Salmonella enterica, Escherichia coli O157:H7, and Vibrio parahaemolyticus) detection was successfully performed with a detection sensitivity of 4 cells per 3.2 μL of milk samples within 30 min. By implementing the direct-PRA on the miniaturized centrifugal microsystem, the on-site food poisoning bacteria analysis would be feasible with high speed, sensitivity, and multiplicity.

How medical students learn and develop the characteristics associated with good teaching in medicine is not well known. Information about this process can improve the academic preparation of medical students for teaching responsibilities. The purpose of this study was to determine how different experiences contributed to the knowledge, skills, and attitudes of medical school graduates and students regarding medical teaching. A questionnaire was developed, addressing reliability and validity considerations, and given to first year residents and third year medical students (taught by those residents). Completed questionnaires were collected from 76 residents and 110 students (81% of the sample group). Item responses were analysed using descriptive and inferential statistics. Most residents (n = 54; 71%) positively viewed opportunities they had to practice teaching when they were seniors. Residents rated three activities for learning to teach highest: (1) observing teachers as they teach; (2) reviewing the material to be taught; and (3) directly teaching students; representing both individual and participatory ways of learning. Residents' self ratings of teaching behaviours improved over time and this self assessment by the residents was validated by the students' responses. Comparison between residents' self ratings and students' views of typical resident teaching behaviours showed agreement on levels of competence, confidence, and motivation. The students rated characteristics of enthusiasm, organisation, and fulfilment lower (pteaching responsibilities positively and showed agreement on characteristics of good teaching that may be helpful indicators in the process of developing medical teachers.

The available methods to determine the response time of nuclear safety related pressure transducers are discussed, with emphasis to the direct method. In order to perform the experiments, a Hydraulic Ramp Generator was built. The equipment produces ramp pressure transients simultaneously to a reference transducer and to the transducer under test. The time lag between the output of the two transducers, when they reach a predetermined setpoint, is measured as the time delay of the transducer under test. Some results using the direct method to determine the time delay of pressure transducers (1 E Class Conventional) are presented. (author). 18 refs, 35 figs, 12 tabs

Full Text Available An advanced strategic behavior, which we term, “Trojan horse” teaching (ThT, is described. In this type of counteractive behavior, a “teacher”, ostensibly helping his or her rival to learn something, really teaches the rival useless or disadvantageous things. This interaction is an object of interdisciplinary research related to the theory of human capital, the theory of agency, knowledge management, the theory of conflict, and to social and educational psychology. Examples of ThT in real life, and results of experiential studies, including the administration of a survey concerning people’s beliefs about teaching “with evil intent”, and a set of experiments with participation of adults and children, have been described. Possible directions of artificial intelligence systems development related to ThT are described. General relations between: (a counteraction to learning, and (b development in spite of the counteraction are discussed.

Financial Time Series Forecasting Using Directed-Weighted Chunking SVMs

Full Text Available Support vector machines (SVMs are a promising alternative to traditional regression estimation approaches. But, when dealing with massive-scale data set, there exist many problems, such as the long training time and excessive demand of memory space. So, the SVMs algorithm is not suitable to deal with financial time series data. In order to solve these problems, directed-weighted chunking SVMs algorithm is proposed. In this algorithm, the whole training data set is split into several chunks, and then the support vectors are obtained on each subset. Furthermore, the weighted support vector regressions are calculated to obtain the forecast model on the new working data set. Our directed-weighted chunking algorithm provides a new method of support vectors decomposing and combining according to the importance of chunks, which can improve the operation speed without reducing prediction accuracy. Finally, IBM stock daily close prices data are used to verify the validity of the proposed algorithm.

Small-group teaching and learning has achieved an admirable position in medical education and has become more popular as a means of encouraging the students in their studies and enhance the process of deep learning. The main characteristics of small group teaching are active involvement of the learners in entire learning cycle and well defined task orientation with achievable specific aims and objectives in a given time period. The essential components in the development of an ideal small group teaching and learning sessions are preliminary considerations at departmental and institutional level including educational strategies, group composition, physical environment, existing resources, diagnosis of the needs, formulation of the objectives and suitable teaching outline. Small group teaching increases the student interest, teamwork ability, retention of knowledge and skills, enhance transfer of concepts to innovative issues, and improve the self-directed learning. It develops self-motivation, investigating the issues, allows the student to test their thinking and higher-order activities. It also facilitates an adult style of learning, acceptance of personal responsibility for own progress. Moreover, it enhances student-faculty and peer-peer interaction, improves communication skills and provides opportunity to share the responsibility and clarify the points of bafflement.

The significance of music in teaching Turkish

Directory of Open Access Journals (Sweden)

Feyzan Göher Vural

2018-03-01

Full Text Available The whole history of teaching foreign languages is, in a way, a search for the best methodologies of doing so. Methods of teaching can be seen as systems providing the optimal ways of getting basic knowledge of a foreign language for students. The existing wide variety of methods suggests the choice of those most efficient for particular individuals. Each of the methodologies used relies on a number of theoretical underpinnings. This article advances proposals on using music in teaching Turkish as a foreign language, based on the principles of suggestopedia — the psychology of positive teaching developed by G. Lozanov. It is claimed that suggestopedia helps students learn a foreign language 3 to 5 times faster than those who rely on traditional methods of study. Suggestopedia makes colloquial dialogues in a foreign language be pronounced and/or listened to in the same way as music, and music is used as a facilitating and motivating factor, without lyrics. However, teaching based on suggestopedia alone will not suffice, since in the classical form it is limited by adult audiences and small ones to boot. Other peculiarities of students and groups also have to be accounted for, such as their linguistic background: if their first language is a Turkic one, they can be expected to learn Turkish faster, since they are already familiar with the melodic mode of the language. It can nevertheless be postulated that the use of songs in language learning helps develop such skills as vocabulary, rules of grammar and correct pronunciation. Songs facilitate teaching new words, grammatical rules, learning direction, layout, numbers and demonstrative adjectives. This is both useful and interesting for all categories of learners, children as well as adults.

Learning in general practice is an essential component of undergraduate medical education; currently, on average, 13% of clinical placements in the UK are in general practice. However, whether general practice can sustainably deliver more undergraduate placements is uncertain. To identify the geographical distribution of undergraduate teaching practices and their distance from the host medical school. National survey of all medical schools in the UK. All 33 UK medical schools were invited to provide the postcodes of their undergraduate teaching practices. These were collated, de-duplicated, and mapped. The distance in kilometres and journey times by car and public transport between each medical school and its teaching practices was estimated using Transport Direct (www.transportdirect.info). The postcodes of every practice in the UK were obtained from the UK's health departments. All 33 UK medical schools responded; 4392 practices contributed to teaching, with a median (minimum-maximum) of 142 (17-385) practices per school. The median (minimum-maximum) distance between a school and a teaching practice was 28 km (0-1421 km), 41 (0:00-23:26) minutes' travel by car and 1 hour 12 (0:00-17:29) minutes' travel by public transport. All teaching practices were accessible by public transport in one school and 90-99% were in a further four schools; 24 schools had >20% of practices that were inaccessible by public transport. The 4392 undergraduate teaching general practices are widely distributed and potentially any practice, no matter how isolated, could contribute to undergraduate education. However, this is, at the price of a considerable travel burden. © British Journal of General Practice 2014.

By regularly monitoring the most stable millisecond pulsars over many years, pulsar timing arrays (PTAs) are positioned to detect and study correlations in the timing behaviour of those pulsars. Gravitational waves (GWs) from supermassive black hole binaries (SMBHBs) are an exciting potentially detectable source of such correlations. We describe a straightforward technique by which a PTA can be `phased-up' to form time series of the two polarization modes of GWs coming from a particular direction of the sky. Our technique requires no assumptions regarding the time-domain behaviour of a GW signal. This method has already been used to place stringent bounds on GWs from individual SMBHBs in circular orbits. Here, we describe the methodology and demonstrate the versatility of the technique in searches for a wide variety of GW signals including bursts with unmodelled waveforms. Using the first six years of data from the Parkes Pulsar Timing Array, we conduct an all-sky search for a detectable excess of GW power from any direction. For the lines of sight to several nearby massive galaxy clusters, we carry out a more detailed search for GW bursts with memory, which are distinct signatures of SMBHB mergers. In all cases, we find that the data are consistent with noise.

Time-resolved studies of direct effects of radiation on DNA

International Nuclear Information System (INIS)

Fielden, E.M.; O'Neill, P.; Al-Kazwini, A.

1987-01-01

The biological changes induced by ionising radiation are a consequence of radiation-induced chemical events taking place at times <1s. These events are strongly influenced by the presence of chemical modifiers. Since DNA is a principle target for radiation-induced cell killing, DNA-free radicals are generated by direct ionisation of DNA moieties (direct effect) and by reaction with hydroxyl radicals formed by radiolysis of the water which is in the vicinity of the DNA (indirect effect). In order to study the 'direct' effects of radiation on DNA the following model approaches are discussed:- 1) Use of the technique of pulse radiolysis to investigate in aqueous solution the interactions of deoxynucleosides with SO/sub 4//sup .-/ whereby one-electron oxidised species of the bases are generated; and 2) time resolved, radiation-induced changes to solid DNA and related macromolecules (e.g. radiation-induced luminescence) in order to obtain an understanding of charge/energy migration as a result of ionisation of DNA. The influence of chemical modifiers and of environment is discussed in terms of the properties of the radiation-induced species produced. Since the properties of base radicals produced by SO/sub 4//sup .-/ are similar to those of the base OH-adducts oxidising properties, potential similarities between the 'direct' and 'indirect' effects of radiation are presented

Time for Education: Ontology, Epistemology and Discursiveness in Teaching Fundamental Scientific Topics

Plakitsi, Katerina; Kokkotas, Vasilis

2010-01-01

Science has the character of construction of explicative normative models, whose semantic value is assessed instrumentally, through the quantified corroboration of predictions, or their compliance with the facts, constituting a separate world. But we oppose to its approach as a "logistic" activity, depraved of any ontological substantiation, since, this would ignore the meditative or interpretive features salient in it. The ontological appropriation of the world is a multidisciplinary task, which cannot be integrated without a form that combines argumentation with a meaningful discourse, open to culture.The view of learning science as culture acquisition affords an intuitive, holistic, and rich appreciation of students' experiences in a science classroom. Common cultural mediators in science education are narratives. McClosky and Bruner have been long-time advocates of the use of narrative in education. As a case study, we applied a both cultural and ontological approach to the teaching of time in primary education.

A significant benefit of virtual reality (VR) simulation is the ability to provide self-direct learning for trainees. This study aims to determine whether there are any differences in performance of cadaver temporal bone dissections between novices who received traditional teaching methods and those who received unsupervised self-directed learning in a VR temporal bone simulator. Randomized blinded control trial. Royal Victorian Eye and Ear Hospital. Twenty novice trainees. After receiving an hour lecture, participants were randomized into 2 groups to receive an additional 2 hours of training via traditional teaching methods or self-directed learning using a VR simulator with automated guidance. The simulation environment presented participants with structured training tasks, which were accompanied by real-time computer-generated feedback as well as real operative videos and photos. After the training, trainees were asked to perform a cortical mastoidectomy on a cadaveric temporal bone. The dissection was videotaped and assessed by 3 otologists blinded to participants' teaching group. The overall performance scores of the simulator-based training group were significantly higher than those of the traditional training group (67% vs 29%; P < .001), with an intraclass correlation coefficient of 0.93, indicating excellent interrater reliability. Using other assessments of performance, such as injury size, the VR simulator-based training group also performed better than the traditional group. This study indicates that self-directed learning on VR simulators can be used to improve performance on cadaver dissection in novice trainees compared with traditional teaching methods alone.

With the move toward training Medical Radiation Technologists in technical colleges and universities, qualified staff are being thrust into the position of becoming clinical supervisors. Many of us have no teaching training at all and are there styles in students and in oneself, and the use of different teaching methods/aids that are available. Evaluation of the training process and the progress of the student is important, as is feedback from both directions. There are basic guidelines of which supervisors should be aware. By understanding the different learning styles, clinical supervisors will be able to adapt their teaching to maximize the benefit to the student. 3 figs

Professional development in college science teaching

Science.gov (United States)

Thomas, Aimee Kathryn

Graduate students earning a doctorate in the sciences historically focus their work on research and not professional development in college science teaching. However, for those who go on to a career in academia, a majority of their time will be dedicated to teaching. During the past few years, graduate teaching assistants (GTAs) have been prepared to teach by attending a daylong workshop that included logistical information, but left pedagogy largely unexplored. Since that time, a seminar has been added to provide an introduction to pedagogical theory and practices and to provide practice teaching in the biological sciences laboratory course. Yet, more pedagogical preparation is needed. This study was conducted to determine if there was a need for a teaching certificate program for doctoral students in the College of Science and Technology (CoST) at The University of Southern Mississippi. The GTA respondents studied set teaching goals that were consistent with faculty members across the country; however, this research went further by finding out how competent the GTAs perceived they were and how much support they perceived they needed with respect to teaching and professional development. The GTAs did not differ in their perceived level of competence based on experience level; however, the less experienced GTAs did perceive they needed more support than the experienced GTAs. To help GTAs develop a skill set that many CoST graduates currently lack, it is recommended that the University provide ample training and supervision. Establishing a certificate program can potentially impact the community in the following ways: (1) the training of GTAs contributes to the academic preparation of future academic professionals who will be teaching in various institutions; (2) GTA training provides professional development and awareness that teaching requires life long professional development; (3) ensuring competent academicians, not only in content but also in pedagogy; (4

Full Text Available We present a tunable diode laser spectrometer with a novel, rapid time multiplexed direct absorption- and wavelength modulation-spectroscopy operation mode. The new technique allows enhancing the precision and dynamic range of a tunable diode laser absorption spectrometer without sacrificing accuracy. The spectroscopic technique combines the benefits of absolute concentration measurements using calibration-free direct tunable diode laser absorption spectroscopy (dTDLAS with the enhanced noise rejection of wavelength modulation spectroscopy (WMS. In this work we demonstrate for the first time a 125 Hz time division multiplexed (TDM-dTDLAS-WMS spectroscopic scheme by alternating the modulation of a DFB-laser between a triangle-ramp (dTDLAS and an additional 20 kHz sinusoidal modulation (WMS. The absolute concentration measurement via the dTDLAS-technique allows one to simultaneously calibrate the normalized 2f/1f-signal of the WMS-technique. A dTDLAS/WMS-spectrometer at 1.37 µm for H2O detection was built for experimental validation of the multiplexing scheme over a concentration range from 50 to 3000 ppmV (0.1 MPa, 293 K. A precision of 190 ppbV was achieved with an absorption length of 12.7 cm and an averaging time of two seconds. Our results show a five-fold improvement in precision over the entire concentration range and a significantly decreased averaging time of the spectrometer.

Integrative teaching in Radiology. A survey

International Nuclear Information System (INIS)

Dettmer, S.; Weidemann, J.; Wacker, F.; Fischer, V.

2015-01-01

To survey integrative teaching in radiology at German universities. A questionnaire about radiological education was sent electronically to all 37 chairpersons of university radiology departments in Germany. The questions included the course type, teaching methods, concept, perception, and advantages and disadvantages of integrative teaching. Statistical analysis was performed with nonparametric statistics and chi-square test. The survey was considered representative with a return rate of 68%. Integrative teaching is established at 4/5 of all departments. Integrative teaching is well accepted with an acceptance rate that is significantly higher in so-called 'Modellstudiengaengen' (model courses of study) (100%) compared to conventional courses of study (72%). The advantages of integrative teaching include linking of content (92%) and preparation for interdisciplinary work (76%). The disadvantages include high effort (75%) and time (67%) for organization. Furthermore, there is a risk that basic radiological facts and knowledge cannot be conveyed and that the visibility of radiology as an independent discipline is lost. Conventional radiological teaching has a similarly high acceptance (84%) compared to integrative courses (76%). Integrative teaching has a high acceptance among chairpersons in radiology in Germany despite the greater effort. A good interdisciplinary collaboration is essential for integrative teaching and at the same time this can be conveyed to the students. However, the visibility of radiology as a discipline and the possibility to cover basic radiological content must be ensured. Therefore, both conventional courses and integrative teaching seems reasonable, especially in cross-disciplinary subjects such as radiology.

What is the best way to teach evolution? As microevolution may be configured as a branch of genetics, it being a short conceptual leap from understanding the concepts of mutation and alleles (i.e., genetics) to allele frequency change (i.e., evolution), we hypothesised that learning genetics prior to evolution might improve student understanding of evolution. In the UK, genetics and evolution are typically taught to 14- to 16-y-old secondary school students as separate topics with few links, in no particular order and sometimes with a large time span between. Here, then, we report the results of a large trial into teaching order of evolution and genetics. We modified extant questionnaires to ascertain students’ understanding of evolution and genetics along with acceptance of evolution. Students were assessed prior to teaching, immediately post teaching and again after several months. Teachers were not instructed what to teach, just to teach in a given order. Regardless of order, teaching increased understanding and acceptance, with robust signs of longer-term retention. Importantly, teaching genetics before teaching evolution has a significant (p Teaching genetics first additionally had positive effects on genetics understanding, by increasing knowledge. These results suggest a simple, minimally disruptive, zero-cost intervention to improve evolution understanding: teach genetics first. This same alteration does not, however, result in a significantly increased acceptance of evolution, which reflects a weak correlation between knowledge and acceptance of evolution. Qualitative focus group data highlights the role of authority figures in determination of acceptance. PMID:28542179

The aims of this study were to determine self-directed learning and time management skills of undergraduate nursing students and to investigate the relationship between the concepts. The use of self-directed learning has increased as an educational strategy in recent years. This descriptive and correlational study was conducted with 383 undergraduate nursing students in Turkey. Data were collected using a sociodemographic questionnaire, the Self-Directed Learning Readiness Scale, and Time Management Questionnaire. Mean scores were as follows: self-directed learning readiness, 159.12 (SD = 20.8); time management, 87.75 (SD = 12.1). A moderate positive correlation was found between self-directed learning readiness and time management values. Time management scores were 78.42 when self-directed learning readiness was ≤149 and 90.82 when self-directed learning readiness was ≥ 150, with a statistically significant difference (p = .000). Level of self-directed learning and academic achievement were higher in students who managed their time well.

. Teaching Methods for clinical settings: a review. The teaching process during internship requires several methods to promote the acquisition of more complex technical skills such as relational, decisional and planning abilities. To describe effective teaching methods to promote the learning of relational, decisional and planning skills. A literature review of the teaching methods that have proven most effective, most appreciated by students, and most frequently used in Italian nursing schools. Clinical teaching is a central element to transform clinical experiences during internship in professional competences. The students are gradually brought to become more independent, because they are offered opportunities to practice in real contexts, to receive feedback, to have positive role models, to become more autonomous: all elements that facilitate and potentiate learning. Clinical teaching should be based on a variety of methods. The students value a gradual progression both in clinical experiences and teaching strategies from more supervised methods to methods more oriented towards reflecting on clinical practice and self-directed learning.

Direct ophthalmoscopy is an important clinical skill that is often poorly performed by medical professionals and students. This is attributable to a declining emphasis on ophthalmology in medical school. We present and evaluate a self-directed approach of teaching ophthalmoscopy to medical students that is suitable for the current medical curriculum. Prospective medical education trial. Ninety-five second-year medical students at Queen's University: 32 in the experimental group and 63 in the control group. The experimental group consisted of medical students who practised ophthalmoscopy with one another using an online peer fundus photograph matching exercise created by the Department of Ophthalmology at Queen's University. To use the program, students first examined a peer with an ophthalmoscope and then selected an online photograph of a fundus corresponding to that of the examinee. The program notifies students if a correct selection is made. To encourage use of the program, students participated in a 2-week ophthalmoscopy competition during their ophthalmology rotation. The control group consisted of students who did not participate in the learning exercise. On assessment at the end of the ophthalmology rotation, the experimental group (n = 32) was more accurate in matching fundus photographs compared with the control group (n = 63) (p = 0.02). Participants were faster at performing ophthalmoscopy at the end of the learning exercise (p peer fundus photographs in a self-directed manner appeared to increase the skill and confidence of medical students in ophthalmoscopy.

The emerging subspecialty of regional anesthesiology and acute pain medicine represents an opportunity to evaluate critically the current methods of teaching regional anesthesia techniques and the practice of acute pain medicine. To date, there have been a wide variety of simulation applications in this field, and efficacy has largely been assumed. However, a thorough review of the literature reveals that effective teaching strategies, including simulation, in regional anesthesiology and acute pain medicine are not established completely yet. Future research should be directed toward comparative-effectiveness of simulation versus other accepted teaching methods, exploring the combination of procedural training with realistic clinical scenarios, and the application of simulation-based teaching curricula to a wider range of learner, from the student to the practicing physician.

Geriatric education is a required component of internal medicine training. Work hour rules and hectic schedules have challenged residency training programs to develop and utilize innovative teaching methods. In this study, the authors examined the use of academic detailing as a teaching intervention in their residents' clinic and on the general medicine inpatient wards to improve clinical knowledge and skills in geriatric care. The authors found that this teaching method enables efficient, directed education without disrupting patient care. We were able to show improvements in medical knowledge as well as self-efficacy across multiple geriatric topics.

Se apoya en teorías sociológicas y educativas: Heller, Bourdieu, Freire, Gramsci; así como autores del ocio: Sue y Cuenca. Describe datos obtenidos de un estudio de caso sobre las vivencias de ocio, desde una narrativa fenomenológica, obtenidos de entrevistas. La etnografía en el aula se empleó para describir la práctica docente e identificar las estructuras de ésta. La hermenéutica auxilió en la interpretación de estos datos y en la construcción de los siguientes tipos ideales de ocio-práctica docente: un ocio aburrido se asocia a una maestra autoritaria, o, a un maestro que renuncia a educar; un ocio creativo a maestras y maestros emancipadores; un ocio híbrido a maestros y maestras en ciernes, que aún no definen un tipo de práctica docente. Se concluye que el ocio sí está presente en la práctica docente, que no hay fronteras per se entre lo público y privado. El maestro y maestra es más que un profesionista cuando está frente a grupo, es una persona que pone en juego lo que es y tiene. El ocio imprime una característica singular a la práctica docente como apropiación de conocimientos y cultura.Abstract: This article contains the results of a research study on the tie between leisure time activities and teaching methods among elementary school teachers in the City of Santiago de Querétaro, México.

Full Text Available Nowadays the training-educational process is a dynamic and complex process which uses both classical and modern teaching methods in order to obtain performance in education. Even though traditional teaching methods have a formal character interaction between teacher and students, this is face-to-face and therefore students can give an immediate feedback. From this point of view classical teaching methods are important from time to time. In Romania, in the European context the role of effective learning strategies represents the key point for the education process. The role of teachers in developing creativity to those students who want to learn in an interactive way is very important because they should imply that students directly in the training -educational process. In this context the educational process must be student centered because only in this way their critical thinking and creativity is developed. We can say that when non-formal and informal learning is combined with formal learning the scope of pedagogy is accomplish. In contemporary context education is regarded as an innovative concept which is used to produce performance at the individual level and also, at institutional level, education provides support in order to build strategies according to the challenges from the labour market. The paper is based on a qualitative research, conducted on a sample of 100 people aged between 19 and 23 years old (students at a Business School. The key question raised at this point is: What is the role of classical and modern teaching methods in training-educational process? The objectives of this study are the following: 1. highlighting the context of higher education in Romania; 2. presenting the role of university strategy in contemporary context; 3. highlighting the importance of using classical/modern teaching methods in business education; 4. presenting the role of innovation and creativity in business education; 5. presenting the analysis

Full Text Available The integumentary system (skin is the first line of defence in the body and part of the innate immune system. Within first year modules on Pharmaceutical Biology and Integrative Physiology in the Masters of Pharmacy degree at Robert Gordon University (RGU several software tools were used to support both lecture and coursework material for the immune and integumentary systems. However, students had difficulty visualizing the various layers of the skin and how they become affected by different skin lesions. As a response to these identified learning difficulties, a just-in-time teaching 3-Dimensional elearning object was developed using free-to-use 3D CAD packages alongside common elearning software. The outcome was a virtualised human arm equipped to illustrate and label primary or secondary skin lesions whilst allowing spatial manipulation of the arm. This allowed students to manipulate and identify the specific skin layers involved. Evaluation of student engagement and learning was favourable, with students reflecting that they had a better understanding of the topic. Initial findings from this study highlight the benefits of quick, low-cost 3D production processes as just-in-time teaching elearning tools that have a positive impact on students’ performance.

Automated and angular time-synchronized directional gamma-ray scintillation sensor

International Nuclear Information System (INIS)

Kronenberg, S.; Brucker, G.J.

1998-01-01

The authors' previous research resulted in directional sensors for gamma rays and X rays that have a 4π solid angle of acceptance and, at the same time, a high angular resolution that is limited only by their ability to measure small angles. Angular resolution of ∼1 s of arc was achieved. These sensors are capable of operating and accurately detecting high and very low intensity radiation patterns. Such a system can also be used to image broad area sources and their scattering patterns. The principle of operation and design of directional sensors used in this study was described elsewhere; however, for convenience, a part of that text is repeated here. It was shown analytically that the angular distribution of radiation incident on the sensor is proportional to the first derivative of the scan data, that is, of the events' count rate versus orientation of the detector. The previously published results were obtained with a annual operating system. The detector assembly was set at a specific angle, and a pulse rate count was made. This was repeated at numerous other angles of orientation, a time-consuming and labor-intensive process. Recently, the authors automated this system, which is based on the detection of scintillations. The detector, which consists of a stack of plates of Lucite, plastic scintillator, and lead foils, rotates by means of a motor in front of a stationary photomultiplier tube (PMT). One revolution per second was chosen for the motor. At time zero, a trigger indicates that a revolution has started. The angle of orientation of the detector in the laboratory system is proportional to the time during one revolution. The process repeats itself a desired number of times. The trigger signal initiates a scan of a multichannel scalar (MCS). The detector assembly is allowed to rotate in the radiation field, and the MCS scans are repeated in an accumulated mode of operation until enough events are collected for the location of the radiation source to be

The entire healthcare workforce needs to be educated to better care for older adults. The purpose of this study was to determine whether fellows are being trained to teach, to assess the attitudes of fellowship directors toward training fellows to be teachers, and to understand how to facilitate this type of training for fellows. A nine-question survey adapted from a 2001 survey issued to residency program directors inquiring about residents-as-teachers curricula was developed and administered. The survey was issued electronically and sent out three times over a 6-week period. Of 144 ACGME-accredited geriatric fellowship directors from geriatric, internal medicine, and family medicine departments who were e-mailed the survey, 101 (70%) responded; 75% had an academic affiliation, 15% had a community affiliation, and 10% did not report. Academic and community programs required their fellows to teach, but just 55% of academic and 29% of community programs offered teaching skills instruction as part of their fellowship curriculum; 67% of academic programs and 79% of community programs felt that their fellows would benefit from more teaching skill instruction. Program directors listed fellow (39%) and faculty (46%) time constraints as obstacles to creation and implementation of a teaching curriculum. The majority of fellowship directors believe that it is important for geriatric fellows to become competent educators, but only approximately half of programs currently provide formal instruction in teaching skills. A reproducible, accessible curriculum on teaching to teach that includes a rigorous evaluation component should be created for geriatrics fellowship programs. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

Offset-Free Direct Power Control of DFIG Under Continuous-Time Model Predictive Control

DEFF Research Database (Denmark)

Errouissi, Rachid; Al-Durra, Ahmed; Muyeen, S.M.

2017-01-01

This paper presents a robust continuous-time model predictive direct power control for doubly fed induction generator (DFIG). The proposed approach uses Taylor series expansion to predict the stator current in the synchronous reference frame over a finite time horizon. The predicted stator current...... is directly used to compute the required rotor voltage in order to minimize the difference between the actual stator currents and their references over the predictive time. However, as the proposed strategy is sensitive to parameter variations and external disturbances, a disturbance observer is embedded...... into the control loop to remove the steady-state error of the stator current. It turns out that the steady-state and the transient performances can be identified by simple design parameters. In this paper, the reference of the stator current is directly calculated from the desired stator active and reactive powers...

[Meeting the needs of the European working time directive in german medical profession].

Science.gov (United States)

Friedrich, M; Popov, A F; Schmitto, J D; Bireta, C; Emmert, A; Tirilomis, T

2011-06-01

The legal obligation of the European Working Time Directive with its implementation into a German Working Hours Act requires German hospitals to give up old structures and requires the implementation of new working time models. The failure of the revision of the European Working Time Directive in April 2009 prevented that any changes of status quo might happen in the near future. Fundamental terms of the working law for the medical area have been elucidated and have been implemented into concrete calculation formulas. The planned working time has been clearly determined. Particularly, on-call duties and a signed "OptOut-declaration" have huge effects on the upper limit of the working time that is to be determined. Shift duty leads to the greatest limitations of the upper limit of the working time. The Working Hours Act defines the maximal, available, individual working time budget and thus the working time budget of a hospital and it limits the maximal availability of the service providers of a hospital as well as defining the maximal personnel costs. Transparency in this area lays the foundation for an effective time management and the creation of new working time models in accordance with the European Working Time Directive as well as the Working Hours Act and the "TVÄ" (labour contract for doctors at municipal hospitals). It is possible, with the knowledge of the maximal working time budget and the thereof resulting personnel costs, to calculate the economical revenues better. The reallocation of the working time of doctors enables efficiency enhancement. It is necessary to demand a clear definition of the tasks of doctors with the consequential discharge of tasks that should not/do not belong to the responsibilities of a doctor. This would lead to a more attractive working environment for doctors at hospitals and thus to an improvement of the care of the patients. The implementation of the European Time Directive is not to be seen as unrealizable, as has been

Dimension reduction of frequency-based direct Granger causality measures on short time series.

Science.gov (United States)

Siggiridou, Elsa; Kimiskidis, Vasilios K; Kugiumtzis, Dimitris

2017-09-01

The mainstream in the estimation of effective brain connectivity relies on Granger causality measures in the frequency domain. If the measure is meant to capture direct causal effects accounting for the presence of other observed variables, as in multi-channel electroencephalograms (EEG), typically the fit of a vector autoregressive (VAR) model on the multivariate time series is required. For short time series of many variables, the estimation of VAR may not be stable requiring dimension reduction resulting in restricted or sparse VAR models. The restricted VAR obtained by the modified backward-in-time selection method (mBTS) is adapted to the generalized partial directed coherence (GPDC), termed restricted GPDC (RGPDC). Dimension reduction on other frequency based measures, such the direct directed transfer function (dDTF), is straightforward. First, a simulation study using linear stochastic multivariate systems is conducted and RGPDC is favorably compared to GPDC on short time series in terms of sensitivity and specificity. Then the two measures are tested for their ability to detect changes in brain connectivity during an epileptiform discharge (ED) from multi-channel scalp EEG. It is shown that RGPDC identifies better than GPDC the connectivity structure of the simulated systems, as well as changes in the brain connectivity, and is less dependent on the free parameter of VAR order. The proposed dimension reduction in frequency measures based on VAR constitutes an appropriate strategy to estimate reliably brain networks within short-time windows. Copyright © 2017 Elsevier B.V.

Teaching medical anatomy: what is the role of imaging today?

Science.gov (United States)

Grignon, Bruno; Oldrini, Guillaume; Walter, Frédéric

2016-03-01

Medical anatomy instruction has been an important issue of debate for many years and imaging anatomy has become an increasingly important component in the field, the role of which has not yet been clearly defined. The aim of the paper was to assess the current deployment of medical imaging in the teaching of anatomy by means of a review of the literature. A systematic search was performed using the electronic database PubMed, ScienceDirect and various publisher databases, with combinations of the relevant MeSH terms. A manual research was added. In most academic curricula, imaging anatomy has been integrated as a part of anatomical education, taught using a very wide variety of strategies. Considerable variation in the time allocation, content and delivery of medical imaging in teaching human anatomy was identified. Given this considerable variation, an objective assessment remains quite difficult. In most publications, students' perceptions regarding anatomical courses including imaging anatomy were investigated by means of questionnaires and, regardless of the method of teaching, it was globally concluded that imaging anatomy enhanced the quality and efficiency of instruction in human anatomy. More objective evaluation based on an increase in students' performance on course examinations or on specific tests performed before and after teaching sessions showed positive results in numerous cases, while mixed results were also indicated by other studies. A relative standardization could be useful in improving the teaching of imaging anatomy, to facilitate its assessment and reinforce its effectiveness.

Full Text Available Modern learning foreign languages is based on a humanistic paradigm. The realization of the possibility of such activity researches consider in implementation of technological approach in educational process. The scientists connect the optimal and qualitative realization of this activity with the implementation of education technology into learning process. Modern studies are focused on questions of implementation of technological approach into teaching foreign languages. It is thought to allow to achieve guaranteed minimal level of learning results. At the same time there are some incompletely studied aspects such as content of pedagogical technologies, their conceptual and procedural characteristics, approaches to classification. In the article the essence of technological approach is revealed, the communicatively focused technologies of teaching foreign languages in non-linguistic universities are concretized. The interpretation of technological approach is given; characteristics and attributes in teaching foreign languages are selected. It is noticed that technological approach is social and engineering ideology in the sphere of didactics according to which teaching process is considered to be a completely designed process with strictly planned and fixed results (M. Klarin. In the article it is emphasized on feasibility and efficiency of technological approach while teaching foreign languages, the degree of its integration in educational process is defined. The communication-oriented technologies, based on a communicative method of E. Passov, are allocated as the most optimum. It is shown the communication-oriented technologies go beyond the conceptual idea of modelling in teaching process of real foreign-language communication, and their procedural component and contents are founded on certain principles. The most commonly used technologies of teaching foreign languages are classified as technologies of modernization and technologies of

Fink, D J

1980-07-01

University teaching hospitals face increasing competition from community hospitals, expanding regulation of health care, a rising tide of consumerism, and in many cases a declining urban population base. These problems, which may threaten the teaching hospital's ability to continue tertiary care, teaching, and research functions, may be solved with the aid of new marketing strategies. In developing its marketing strategy, a hospital must assess its strengths and weaknesses, specify its goals in measurable terms, implement tactics to achieve these goals, and evaluate its marketing program. The strategies should be directed toward achieving better relationships with institutions, practitioners, and surrounding communities and increasing patient, visitor, and employee satisfaction. A wide variety of programs can be used to reach these goals and to help teaching hospitals meet the competitive challenges of this decade.

Interarrival times of message propagation on directed networks

Mihaljev, Tamara; de Arcangelis, Lucilla; Herrmann, Hans J.

2011-08-01

One of the challenges in fighting cybercrime is to understand the dynamics of message propagation on botnets, networks of infected computers used to send viruses, unsolicited commercial emails (SPAM) or denial of service attacks. We map this problem to the propagation of multiple random walkers on directed networks and we evaluate the interarrival time distribution between successive walkers arriving at a target. We show that the temporal organization of this process, which models information propagation on unstructured peer to peer networks, has the same features as SPAM reaching a single user. We study the behavior of the message interarrival time distribution on three different network topologies using two different rules for sending messages. In all networks the propagation is not a pure Poisson process. It shows universal features on Poissonian networks and a more complex behavior on scale free networks. Results open the possibility to indirectly learn about the process of sending messages on networks with unknown topologies, by studying interarrival times at any node of the network.

This study examines the perceived impact of a novel clinical teaching method based on FAIR principles (feedback, activity, individuality and relevance) on students' learning on clinical placement. This was a qualitative research study. Participants were third year and final year medical students attached to one UK vascular firm over a four-year period (N=108). Students were asked to write a reflective essay on how FAIRness approach differs from previous clinical placement, and its advantages and disadvantages. Essays were thematically analysed and globally rated (positive, negative or neutral) by two independent researchers. Over 90% of essays reported positive experiences of feedback, activity, individuality and relevance model. The model provided multifaceted feedback; active participation; longitudinal improvement; relevance to stage of learning and future goals; structured teaching; professional development; safe learning environment; consultant involvement in teaching. Students perceived preparation for tutorials to be time intensive for tutors/students; a lack of teaching on medical sciences and direct observation of performance; more than once weekly sessions would be beneficial; some issues with peer and public feedback, relevance to upcoming exam and large group sizes. Students described negative experiences of "standard" clinical teaching. Progressive teaching programmes based on the FAIRness principles, feedback, activity, individuality and relevance, could be used as a model to improve current undergraduate clinical teaching.

The importance of understanding during the teaching process

Directory of Open Access Journals (Sweden)

Dubljanin Saša

2015-01-01

Full Text Available Learning in the teaching process often goes on without proper understanding which is one of important problems that modern didactics tries to solve. In order to direct the totality of teaching towards understanding it is necessary to answer the question what understanding is, which is why we analysed different philosophical views on the concept of understanding and stressed their semblance to pedagogic explanations. Different kinds of understanding were analyzed as well as their role and contribution in different teaching situations, especially in the context of problem solving. As an alternative to the teaching based on accumulation of knowledge the characteristics and some principles of teaching focused on understanding are described, and the need for stimulating and developing understanding as an important goal of education. The results of our research unequivocally show that learning with understanding enables students to memorize the teaching material better, as well as to understand the whole teaching subject and efficiently apply the acquired knowledge out of school, and leads to more flexible behaviour and better coping in everyday life.

Full Text Available Teaching is a mirror that reveals how a nation defines and limits its identity in history, taking its landmarks at cultural level. The situation of education in Bukovina during the Austrian occupation was precarious, especially in the presence of the Romanian language in schools. In that sense, the Romanians of Bukovina fought against the preponderance of German language, imposed by the Austrian occupation and against the pressure exerted by the Ukrainians to impose their mother tongue in educational institutions. If the quality of the teaching of the first schools remained at a fairly low level, the time has come when, following the Western model, Bukovina raised the level of its institutions. The Theological Institute which turns into the Faculty of Theology so that the University of Tchernivtsi allowed students to complete their studies in Bukovina, without having to study in the academic centers of Liov or Vienna.

2010-01-01

This research investigates the effectiveness of several commonly used methods for teaching the causes of moon phases to sixth grade students. Common teaching methods being investigated are the use of diagrams, animations, modeling/kinesthetics and direct observations of moon phases using a planetarium. Data for each method will be measured by a pre and post assessment of students understanding of moon phases taught using one of the methods. The data will then be used to evaluate the effectiveness of each teaching method individually and comparatively, as well as the method's ability to discourage common misconceptions about moon phases. Results from this research will provide foundational data for the development of educational planetarium shows for the deaf or other linguistically disadvantage children.

The identification of teaching interactions used in one-to-one teaching of number in the early years of schooling

Directory of Open Access Journals (Sweden)

Bronwyn Ewing

2016-12-01

Full Text Available This research paper reports on phase one of an investigation of video recorded intensive one-to-one teaching interactions with 6–7-year-old students who were in their second year of schooling in Australia and identified by the their teacher as low attaining in early number. The two-phased study from which this paper emerges was originally conducted in 1998 as part of my Bachelor of Teaching Honours (Research program at Southern Cross University Lismore, New South Wales. That study identified teaching interactions particularly suited to one-to-one teaching in the Maths Recovery Program, a program designed for these students who were at risk of failure in early number. Since that time a great deal has not changed with limited literature available that comprehensively reports on teaching interactions in intensive one-to-one settings. Revisiting the original study is considered timely given the increasing number of withdrawal and intensive programs now funded and adopted by schools and yet, rarely reported on in terms of the effectiveness of the teaching interactions that occur in such settings. This paper then presents a discussion of a preliminary series of teaching interactions that either positively and or negatively influence an intensive one-to-one teaching and learning setting.

Bringing Scholarship to the Classroom: Strategies for promoting research through teaching

Directory of Open Access Journals (Sweden)

Alisa Gaunder

2008-10-01

Full Text Available An issue all academics grapple with is how to strike the desired balance between research and teaching. This balance is heavily influenced by the type of institution where one seeks employment. At liberal arts colleges, excellence is expected in the classroom and a premium is put on faculty student interaction. The expectation, however, is to be teacher-scholar, not simply teacher. And indeed, the desire of most professors at liberal arts colleges is to remain active in their field. With limited time and large teaching demands, the challenge becomes one of continuously making progress on one’s research agenda. When asked to consider how to connect scholarship and teaching on the “Bringing Scholarship to the Classroom: Japan Studies” panel at the ASIANetwork conference in March 2008, I realized I had developed several strategies to link my research and teaching. What I also realized was that all these strategies were influenced by the fact that I was a junior professor vying for tenure. That is, my motivation for connecting scholarship and teaching was largely instrumental. In addition to being able to speak more passionately about topics we research and therefore engage students more fully, I would argue that finding ways to incorporate one’s research in as many classes as possible is a way to better tackle the dual role of teacher-scholar. Connecting research and teaching can accelerate one’s research agenda simply by preventing the liberal arts professor from being torn in too many different directions.

Salimi, S.; Jafarizadeh, M. A.

2009-01-01

In this paper we define direct product of graphs and give a recipe for obtaining probability of observing particle on vertices in the continuous-time classical and quantum random walk. In the recipe, the probability of observing particle on direct product of graph is obtained by multiplication of probability on the corresponding to sub-graphs, where this method is useful to determining probability of walk on complicated graphs. Using this method, we calculate the probability of continuous-time classical and quantum random walks on many of finite direct product Cayley graphs (complete cycle, complete K n , charter and n-cube). Also, we inquire that the classical state the stationary uniform distribution is reached as t → ∞ but for quantum state is not always satisfied. (general)

The European Working Time Directive: a practical review for surgical trainees.

Science.gov (United States)

Fitzgerald, J E F; Caesar, B C

2012-01-01

The European Working Time Directive (EWTD) 2003/88/EC is a Union Directive laying down minimum health and safety requirements for the organisation of working time. Originally primarily intended as labour law, its progressive introduction up to full implementation for doctors-in-training in August 2009 has substantially reduced duty-hours and caused widespread concern in surgery. Detrimental effects on the continuity of patient care, reduced availability of medical staff with associated rota difficulties, and the reduction in time for training junior doctors have been widely cited. Craft-specialities such as surgery and those providing an acute service have faced particular challenges. This review offers a practical guide for surgical trainees, explaining the European regulations in the context of current terms and conditions of doctor's employment in the UK. Information is provided on protecting training, opting-out, seeking remuneration for this, and ensuring doctors and patients are protected with appropriate medical indemnity cover in place.

EDUCATION IN TIMES NET GENERATION: HOW DIGITAL IMMIGRANTS CAN TEACH DIGITAL NATIVES

Directory of Open Access Journals (Sweden)

Hamilton Viana Chaves

2016-04-01

Full Text Available Members of the knowledge society, of the network society or of the informatics society are some names that seem to define the current generation. Net generation is a generic nomenclature which covers all the previous terms. Digital immigrants are the subjects whom were born before the advent of digital technologies and who joined to them. Digital natives are the subjects whom were born in the current generation and that would have special qualities, especially regarding the learning process. Considering all this context, a question arises: how the digital immigrants teach the digital natives? This item justifies itself because there is a meeting of generations, in theory, significantly differentiated. Due to this, it would be necessary to identify the appropriate educational forms according to the presented situation. Our teaching experience convinces us that, yes, we should valorize the information’s technologies and communication, understanding that these are means, not ends. It is important to highlight that any tool causes advances and regressions, a fact that serves to guide our teaching practice.

Direct determination of scattering time delays using the R-matrix propagation method

International Nuclear Information System (INIS)

Walker, R.B.; Hayes, E.F.

1989-01-01

A direct method for determining time delays for scattering processes is developed using the R-matrix propagation method. The procedure involves the simultaneous generation of the global R matrix and its energy derivative. The necessary expressions to obtain the energy derivative of the S matrix are relatively simple and involve many of the same matrix elements required for the R-matrix propagation method. This method is applied to a simple model for a chemical reaction that displays sharp resonance features. The test results of the direct method are shown to be in excellent agreement with the traditional numerical differentiation method for scattering energies near the resonance energy. However, for sharp resonances the numerical differentiation method requires calculation of the S-matrix elements at many closely spaced energies. Since the direct method presented here involves calculations at only a single energy, one is able to generate accurate energy derivatives and time delays much more efficiently and reliably

What does an intern doctor actually do? A quantification of time on work activities

Directory of Open Access Journals (Sweden)

James Jia Jun Chen

2017-12-01

Full Text Available Background Interns, or first year junior doctors, have traditionally been used as an adaptable frontline solution to many of the changes in healthcare, utilising their broad skill sets for both direct patient care and administrative burdens. While there are studies that focus on the total hours junior doctors work, there are few that analyse the specific tasks they do and how they dedicate their work time. Aims We aim to quantify the amount of time intern doctors spent on specific tasks during a shift. Methods This is a multi-centred, retrospective, self-reported study that was carried out in a public tertiary hospital network in Western Australia, comprising one tertiary, two metropolitan, and three regional hospitals. 68 individual shifts were reported, accounting for 605.72 hours. Participants reported time spent, in fifteen minute segments, on categories grossly defined as clerical tasks, clinical tasks, teaching, and personal time. Participants were also asked about their satisfaction with the amount of clinical exposure during the reported shift. Results Direct patient care accounted for 22 per cent of total shift time, indirect care 74 per cent, and personal time 4 per cent. Discharge summaries accounted for the most time-per-shift at 26 per cent, followed by medical note documentation at 14 per cent, with the least being teaching at 2 per cent. Direct patient contact by interns during a shift was on average 12 per cent (SD 14 per cent. 12 interns or 18 per cent of all responses reported no direct patient contact (0 per cent during a shift. Interns working in emergency medicine spent 44 per cent of their shift on direct patient contact, significantly more compared to their medicine and surgical colleagues. Conclusion Indirect care activities consume almost three times as much time as direct care activities. Interns are mostly unsatisfied with their amount of clinical exposure per shift. The results concur with the current literature of

Proposal for a collaborative approach to clinical teaching.

Science.gov (United States)

Beckman, Thomas J; Lee, Mark C

2009-04-01

Evidence suggests that inexperienced clinical teachers are often controlling and noninteractive. Adult learning theory states that mature students prefer shared and self-directed learning and that skillful teachers favor facilitating discussions over transmitting knowledge. Similarly, education research shows that effective clinical teachers invest in relationships with learners, ask questions to diagnose learners, communicate complex information clearly, and provide meaningful feedback. On the basis of these principles, we propose a collaborative approach to clinical teaching that has 4 essential components: (1) establish a relationship with the learner, (2) diagnose the learner, (3) use teaching frameworks that engage learners, and (4) develop teaching scripts and a personal philosophy. This article includes suggestions for creating a positive learning climate, asking higher-order questions, providing meaningful feedback, and developing teaching scripts. We believe that practicing this approach, which emphasizes respectful teacher-learner relationships, improves the quality of every clinical teaching encounter.

Future mission studies: Forecasting solar flux directly from its chaotic time series

Science.gov (United States)

Ashrafi, S.

1991-01-01

The mathematical structure of the programs written to construct a nonlinear predictive model to forecast solar flux directly from its time series without reference to any underlying solar physics is presented. This method and the programs are written so that one could apply the same technique to forecast other chaotic time series, such as geomagnetic data, attitude and orbit data, and even financial indexes and stock market data. Perhaps the most important application of this technique to flight dynamics is to model Goddard Trajectory Determination System (GTDS) output of residues between observed position of spacecraft and calculated position with no drag (drag flag = off). This would result in a new model of drag working directly from observed data.

Mandrikas, Achilleas; Stavrou, Dimitrios; Skordoulis, Constantine

2017-07-01

In this paper a teaching-learning sequence (TLS) introducing pre-service elementary teachers (PET) to weather map reading, with emphasis on wind assignment, is presented. The TLS includes activities about recognition of wind symbols, assignment of wind direction and wind speed on a weather map and identification of wind characteristics in a weather forecast. Sixty PET capabilities and difficulties in understanding weather maps were investigated, using inquiry-based learning activities. The results show that most PET became more capable of reading weather maps and assigning wind direction and speed on them. Our results also show that PET could be guided to understand meteorology concepts useful in everyday life and in teaching their future students.

Objectives This study examines the perceived impact of a novel clinical teaching method based on FAIR principles (feedback, activity, individuality and relevance) on students’ learning on clinical placement. Methods This was a qualitative research study. Participants were third year and final year medical students attached to one UK vascular firm over a four-year period (N=108). Students were asked to write a reflective essay on how FAIRness approach differs from previous clinical placement, and its advantages and disadvantages. Essays were thematically analysed and globally rated (positive, negative or neutral) by two independent researchers. Results Over 90% of essays reported positive experiences of feedback, activity, individuality and relevance model.  The model provided multifaceted feedback; active participation; longitudinal improvement; relevance to stage of learning and future goals; structured teaching; professional development; safe learning environment; consultant involvement in teaching. Students perceived preparation for tutorials to be time intensive for tutors/students; a lack of teaching on medical sciences and direct observation of performance; more than once weekly sessions would be beneficial; some issues with peer and public feedback, relevance to upcoming exam and large group sizes. Students described negative experiences of “standard” clinical teaching. Conclusions Progressive teaching programmes based on the FAIRness principles, feedback, activity, individuality and relevance, could be used as a model to improve current undergraduate clinical teaching.

Computed tomography (CT), which uses penetrating radiation from many directions to reconstruct cross-sectional or 3D images of object, has widely applied in medical diagnosis and treatment, industrial NDT and NDE. So it is significant for college students to understand the fundamental of CT. The authors describe the CD-50BG CT instrument developed for experimental teaching at colleges. With 50 mm field-of-view and the translation-rotation scanning mode, the system makes use of a single plastic scintillator + photomultiplier detector and a 137 Cs radioactive source with 0.74 GBq activity, which is housed in a tungsten alloy shield. At the same time, an image processing software has been developed to process the acquired data, so that cross-sectional and 3D images can be reconstructed. High quality images with 1 lp·mm -1 spatial resolution and 1% contrast sensitivity are obtained. So far in China, more than ten institutions including Tsinghua University and Peking University have already applied the system to elementary teaching. (authors)

Sun, Xiaoran; Small, Michael; Zhao, Yi; Xue, Xiaoping

2014-01-01

In this work, we propose a novel method to transform a time series into a weighted and directed network. For a given time series, we first generate a set of segments via a sliding window, and then use a doubly symbolic scheme to characterize every windowed segment by combining absolute amplitude information with an ordinal pattern characterization. Based on this construction, a network can be directly constructed from the given time series: segments corresponding to different symbol-pairs are mapped to network nodes and the temporal succession between nodes is represented by directed links. With this conversion, dynamics underlying the time series has been encoded into the network structure. We illustrate the potential of our networks with a well-studied dynamical model as a benchmark example. Results show that network measures for characterizing global properties can detect the dynamical transitions in the underlying system. Moreover, we employ a random walk algorithm to sample loops in our networks, and find that time series with different dynamics exhibits distinct cycle structure. That is, the relative prevalence of loops with different lengths can be used to identify the underlying dynamics

Although postgraduate trainees play a well-accepted role in medical education, little consideration has traditionally been given to senior undergraduate trainees as teachers. Recently, research has shown senior medical students (SMS) can play an effective teaching role for junior medical students (JMS) in non-clinical medical settings. The purpose of our study was to understand the perceptions of SMSs as teachers in a clinical environment for JMS. All students who participated in our peer-led bedside teaching programme from September 2010 to May 2012 were invited to complete a questionnaire following their teaching session. Fifty-six of 70 JMS (80%) and 15 of 15 SMS (100%) participated. Survey questions addressed learning, bedside experiences, teacher effectiveness and the overall usefulness of these sessions. The data collected were analysed for significance of the perceptions reported. We found students reported positive and statistically significant results in all domains examined. JMS reported that sessions were highly valuable learning, improved confidence and comfort at the bedside, had excellent teaching and were a valuable addition to their clinical skills training. SMS reported getting highly valuable learning through preparation and developing improved comfort in a teaching role. Little consideration has traditionally been given to senior undergraduate trainees as teachers Our findings demonstrate that peer-directed learning in undergraduate medical education can be effectively implemented in the clinical arena. © 2015 John Wiley & Sons Ltd.

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

Science.gov (United States)

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

The impact of decreasing faculty numbers on the nursing shortage has been well documented. Mentoring is recognized as the most significant way to grow and nurture nurse educators. The purpose of this article was to describe the Teaching Mentorship Program within the College of Nursing Department of Biobehavioral Health Science at a Midwestern state university. The program activities are designed to facilitate new faculty members' transition from the role of nurse clinician to the role of nurse educator, to support the implementation of evidence-based teaching practices, and to encourage the development of teaching scholarship. Outcomes of the program include retention of new faculty, improved student satisfaction with the quality of instruction, and increased teaching scholarship activities. The program demonstrates the three hallmarks of an effective mentoring program. First, the program is supported by an institutional culture that values mentoring and provides it with an organizational home. Second, the Associate Department Head and primary mentor has been an educator for 37 years with expertise in curriculum development, program evaluation, and teaching methodologies. Third, because the associate department head's principle role is to implement the program and serve as the primary mentor, her commitment is to provide flexible, timely access to faculty.

Rees-Punia, Erika; Holloway, Alicia; Knauft, David; Schmidt, Michael D

2017-12-01

Recess and physical education time continue to diminish, creating a need for additional physical activity opportunities within the school environment. The use of school gardens as a teaching tool in elementary science and math classes has the potential to increase the proportion of time spent active throughout the school day. Teachers from 4 elementary schools agreed to teach 1 math or science lesson per week in the school garden. Student physical activity time was measured with ActiGraph GT3X accelerometers on 3 garden days and 3 no-garden days at each school. Direct observation was used to quantify the specific garden-related tasks during class. The proportion of time spent active and sedentary was compared on garden and no-garden days. Seventy-four children wore accelerometers, and 75 were observed (86% participation). Children spent a significantly larger proportion of time active on garden days than no-garden days at 3 of the 4 schools. The proportion of time spent sedentary and active differed significantly across the 4 schools. Teaching lessons in the school garden may increase children's physical activity and decrease sedentary time throughout the school day and may be a strategy to promote both health and learning.

Coevolution of teaching activity promotes cooperation

Szolnoki, Attila; Perc, Matjaz

Evolutionary games are studied where the teaching activity of players can evolve in time. Initially all players following either the cooperative or defecting strategy are distributed on a square lattice. The rate of strategy adoption is determined by the payoff difference and a teaching activity characterizing the donor's capability to enforce its strategy on the opponent. Each successful strategy adoption process is accompanied by an increase in the donor's teaching activity. By applying an optimum value of the increment, this simple mechanism spontaneously creates relevant inhomogeneities in the teaching activities that support the maintenance of cooperation for both the prisoner's dilemma and the snowdrift game

Creativity in Teaching

2016-12-01

Full Text Available Background: The research of effective teaching is an actual problem of modern linguistics because of active promotion of its unequal manifestations and amplification of the functional load in various sectors of society. Purpose: The purpose of the analysis is to determine the qualifying and classifying features of creative and effective teacher. Results: A foreign language teacher should develop an attractive manner of communication with students. His straightforward behaviour may be expressed in non-verbal communication, through using sympathetic gestures, voice variation, smile and verbal communication expressed through a good sense of humour, personal examples, using words “we” and “our”. This manner of communication provides for a favourable condition for an atmosphere of open-mindedness and mutual understanding. A creative attitude of a teacher towards the organization of a teaching process is related to the updating of the features like fluidity understood as a spontaneous reaction during classes. The teacher as a person who creates and organises a teaching unit should possess leader’s features. Gaining a position of a group leader provides for an opportunity to arrange undisturbed work without any communication misunderstandings. Learners are given precisely formulated instructions, do the tasks in an effective and efficient manner. Therefore, it should be emphasized that a creative teacher should enjoy the features of a reflective practitioner. Being which constantly learns and improves his qualifications, studies and examines his teaching techniques, introduces changes and some time or another revisits his “beaten tracks”, breaking down routine and habits. Getting rid of habits and routines, teaching in harmony with himself, as well as appropriate selection of methods do guarantee a high comfort of work in a well-motivated group, where due to teacher’s creativity a teaching success is achieved, as expressed in

Marcelos, Maria Fátima; Nagem, Ronaldo Luiz

2012-04-01

This work discusses the use of Darwin's `Tree of Life' as a didactic analogy and metaphor in teaching evolution. It investigates whether biology teachers of pupils from 17 to 18 years old know Darwin's text `Tree of Life'. In addition, it examines whether those teachers systematically employ either the analogies present in that text or other analogies between the tree and evolution, and whether they adopt a specific methodology for teaching with analogies and metaphors (A&M). The academic training of teachers regarding use of A&M is review briefly. A diagnostic study was carried out with biology teachers in a public school in the town of Contagem in the state of Minas Gerais in Brazil. The data were obtained through direct observation, questionnaires and a focus group. The teachers pointed out in the questionnaires that some details of Darwin's analogy are utilized as a resource. However, analysis of the data indicates that the `Tree of Life' text is not known or utilized in class. At the same time, the teachers state that they use aspects of the tree as a didactic resource to teach evolution and that its use facilitates the learning of content. The teachers have little knowledge of specific methodologies of teaching with analogies and metaphors, revealing that their training is incomplete in this area.

Full Text Available Abstract 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

Full Text Available Abstract Background Hospital physicians' time is a critical resource in medical care. Two aspects are of interest. First, the time spent in direct patient contact – a key principle of effective medical care. Second, simultaneous task performance ('multitasking' which may contribute to medical error, impaired safety behaviour, and stress. There is a call for instruments to assess these aspects. A preliminary study to gain insight into activity patterns, time allocation and simultaneous activities of hospital physicians was carried out. Therefore an observation instrument for time-motion-studies in hospital settings was developed and tested. Methods 35 participant observations of internists and surgeons of a German municipal 300-bed hospital were conducted. Complete day shifts of hospital physicians on wards, emergency ward, intensive care unit, and operating room were continuously observed. Assessed variables of interest were time allocation, share of direct patient contact, and simultaneous activities. Inter-rater agreement of Kappa = .71 points to good reliability of the instrument. Results Hospital physicians spent 25.5% of their time at work in direct contact with patients. Most time was allocated to documentation and conversation with colleagues and nursing staff. Physicians performed parallel simultaneous activities for 17–20% of their work time. Communication with patients, documentation, and conversation with colleagues and nursing staff were the most frequently observed simultaneous activities. Applying logit-linear analyses, specific primary activities increase the probability of particular simultaneous activities. Conclusion Patient-related working time in hospitals is limited. The potential detrimental effects of frequently observed simultaneous activities on performance outcomes need further consideration.

Full Text Available This study investigated effectivenes of a teaching practice course which realized using the microteaching methods. Theparticipants of the study were six student teachers who experienced teaching practices for two times in a real classroomenvironment. Each of the two teaching practices of the student teachers were videotaped. Having observed of the first videorecords the instructur gave the student teachers feedback about their effectiveness in teaching. Analysis of the video recordsrevealed that student teachers achieved a better performance in their second teachings in terms of explaining basic theoriesand principles, identifying and observing necessary teaching roles and behaviours, preparing lesson plans, and conducting moreeffective teaching practices. In light of the these findings, it is suggested that this method should be integrated into teachingpractice courses.

Full Text Available Introduction: The sources of racial disparity in duration of patients’ visits to emergency departments (EDs have not been documented well enough for policymakers to distinguish patient-related factors from hospital- or area-related factors. This study explores the racial disparity in duration of routine visits to EDs at teaching and non-teaching hospitals.Methods: We performed retrospective data analyses and multivariate regression analyses to investigate the racial disparity in duration of routine ED visits at teaching and non-teaching hospitals. The Healthcare Cost and Utilization Project (HCUP State Emergency Department Databases (SEDD were used in the analyses. The data include 4.3 million routine ED visits encountered in Arizona, Massachusetts, and Utah during 2008. We computed duration for each visit by taking the difference between admission and discharge times.Results: The mean duration for a routine ED visit was 238 minutes at teaching hospitals and 175 minutes at non-teaching hospitals. There were significant variations in duration of routine ED visits across race groups at teaching and non-teaching hospitals. The risk-adjusted results show that the mean duration of routine ED visits for Black/African American and Asian patients when compared to visits for white patients was shorter by 10.0 and 3.4%, respectively, at teaching hospitals; and longer by 3.6 and 13.8%, respectively, at non-teaching hospitals. Hispanic patients, on average, experienced 8.7% longer ED stays when compared to white patients at non-teaching hospitals.Conclusion: There is significant racial disparity in the duration of routine ED visits, especially in non-teaching hospitals where non-White patients experience longer ED stays compared to white patients. The variation in duration of routine ED visits at teaching hospitals when compared to non-teaching hospitals was smaller across race groups. [West J Emerg Med. 2013;14(5:529–541.

2017-07-01

Full Text Available Supervisors are expected to observe how student teachers prepare deliver the lesson and conduct themselves as members of teaching profession and are expected to advise the students on how to improve their teaching skills. The present study is a descriptive survey which sought to analyze student teachers perception towards teaching practice as an exercise for grading or improvement and examine student teachers perception towards student-supervisor comments during discussion after classroom assessment. The sample comprised of 50 second year Diploma in Education who had undergone teaching practice in 2016. The students were purposefully sampled. In purposeful sampling the researcher selects the participants because they possess particular characteristics or knowledge being sought. A questionnaire was used to collect data for this study. The findings indicated that majority of student teachers who participated in the teaching practice perceived that the supervisors gave grades which did not reflect the comments made about the teaching performance of the student teacher. Based on the findings recommendations were made among others that assessment should match the comments on areas needing improvement and meaningful accompanying comments should be made to guide student teachers in the desired directions during teaching practice encourage student teachers to try harder or to give credit for work done well.

The introduction of the European Working Time Directive (EWTD) has greatly reduced training hours of surgical residents, which translates into 30% less surgical and clinical experience. Such a dramatic drop in attendance has serious implications such compromised quality of medical care. As the surgical department of the University of Heidelberg, our goal was to establish a model that was compliant with the EWTD while avoiding reduction in quality of patient care and surgical training. We first performed workload analyses and performance statistics for all working areas of our department (operation theater, emergency room, specialized consultations, surgical wards and on-call duties) using personal interviews, time cards, medical documentation software as well as data of the financial- and personnel-controlling sector of our administration. Using that information, we specifically designed an EWTD-compatible work model and implemented it. Surgical wards and operating rooms (ORs) were not compliant with the EWTD. Between 5 pm and 8 pm, three ORs were still operating two-thirds of the time. By creating an extended work shift (7:30 am-7:30 pm), we effectively reduced the workload to less than 49% from 4 pm and 8 am, allowing the combination of an eight-hour working day with a 16-hour on call duty; thus, maximizing surgical resident training and ensuring patient continuity of care while maintaining EDTW guidelines. A precise workload analysis is the key to success. The Heidelberg New Working Time Model provides a legal model, which, by avoiding rotating work shifts, assures quality of patient care and surgical training.

Teaching with iPads

Maj, Hubert

2015-04-01

Bilingual students in high school with bilingual units in Boguchwała have received iPads for learning English and a few subjects using CLIL (biology, basics of entrepreneurship, geography, IT and mathematics). Lessons with iPads are interesting for students for several reasons. First of all, teenagers like new technologies and using iPads for teaching helps students to learn by fun. Secondly, iPads give new possibilities of looking for knowledge about each theme. Moreover, teaching with iPads develops students' engagement. They have a chance to choose a few among over 65 000 applications for gathering and then presenting information about the lesson topic. They can easily prepare presentations, movies, cartoons, mind maps or whatever they like. Teaching students, thanks to the iPads, makes it their initiative, and the teacher can inspire them to look for the knowledge rather than disciplining pupils. But teaching with iPads is connected with many problems. For instance, there are not any examples on how to teach using these tools. It is very up-to-date technology and teachers firstly must learn the possibilities of iPads and look for new applications. It takes much time, especially at the beginning, and is difficult especially for inexperienced teachers. In addition, it is almost impossible to maintain control of the iPads for all of the students during the lesson. They can use their iPads for something unconnected with the topic of the lesson. Thirdly is lack of time - active methods (with iPads as well) are more time-consuming and it could be that they do not finish the whole program. And of course the last, but not at least, is the problem of money. Some of the applications must be paid for, and it is usually obligatory to possess a credit card. Fortunately, it is not expensive - applications usually cost a few euros and many of them are free and really good.

Full Text Available This paper presents a chaotification method based on direct time-delay feedback control for a quasi-zero-stiffness isolation system. An analytical function of time-delay feedback control is derived based on differential-geometry control theory. Furthermore, the feasibility and effectiveness of this method was verified by numerical simulations. Numerical simulations show that this method holds the favorable aspects including the advantage of using tiny control gain, the capability of chaotifying across a large range of parametric domain and the high feasibility of the control implement.

Maggio, Lauren A; Daley, Barbara J; Pratt, Daniel D; Torre, Dario M

2018-05-08

Increasingly health professions education (HPE) faculty are choosing or being required to transition their face-to-face teaching to online teaching. For many faculty, the online learning environment may represent a new context with unfamiliar technology, changing expectations, and unknown challenges. In this context, faculty members may find themselves teaching in ways that are dissonant with the existing assumptions, beliefs, and views that are central to their pedagogical or teaching identity. This "identity dissonance" may lead to dissatisfaction and frustration for the faculty and potentially suboptimal learning experience for students. In this Perspective, the authors propose that faculty consider using Pratt's five teaching perspectives as a conceptual framework to recognize and mitigate potential identity dissonance as they transition to teaching online. Derived and refined through several years of research, these teaching perspectives are based upon interrelated sets of intentions and beliefs that give direction and justification to faculty members' actions. They have been used in higher education to improve faculty satisfaction, self-reflection capabilities, and faculty development. The authors, therefore, believe that these teaching perspectives hold the potential to assist HPE faculty enhance their teaching and retain their primary teaching identify, even as they shift to online teaching. Doing so may ensure that the components of teaching they enjoy and draw self-efficacy from are still central to their teaching experience. Pratt's teaching perspectives also provide a conceptual framework for creating future faculty development initiatives and conducting research to better understand and improve the experience of transitioning to online teaching.Written work prepared by employees of the Federal Government as part of their official duties is, under the U.S. Copyright Act, a "work of the United States Government" for which copyright protection under Title

Martins e Silva, J

1993-10-01

The circumstances preceding the future revision of the medical curriculum are analysed, main internal and external stimuli are described, and sources of resistance to changes in medical training require new educational philosophy, privileging oriented training during undergraduation, as a preliminary phase of medical education. The definition and accompaniment of the general and specific objectives, the strategy and programme used, the design and adequacy of the available support, and the related engagement of all political, academic and socially responsible persons and institutions, are fundamental factors for successful change. The education and training of polyvalent medical doctors requires methodological modifications, namely the definition of a core curriculum, made dynamic through the teaching of interdependent subjects and earlier contact with common clinical problems. Learning through interconnected basic and clinical matters will benefit the technical and psychosocial education of future doctors. The education resulting from a renewal in undergraduate medical education will be mostly determined by organizational and institutional frameworks, teaching methods and the evaluation process used, as well as by teacher commitment, pedagogic and scientific capacities. Professional competence should be the end product of efficient training. Otherwise, undergraduate medical education would not prepare the professional development of the young doctors, thus diminishing the quality of medical training in the future.

Full Text Available Internet teaching is a worthy topic today because changes in society demand "that learners change their knowledge and skill bases and change them faster than at any time in history" [1], and Internet teaching is proving to be one of the best ways to reach those learners. This paper explores ten of the most common difficulties of online courses. It explains how the proper use of readily available technology can be brought to bear on these difficulties in ways that will reduce worry and stress both for beginners faced with teaching a first course and for professors who already have taught online courses but may be seeking ways to improve upon the experience.

Why I teach the controversy: Using creationism to teach critical thinking

Directory of Open Access Journals (Sweden)

P. Lynne eHoney

2015-06-01

Full Text Available Creationism and intelligent design are terms used to describe supernatural explanations for the origin of life, and the diversity of species on this planet. Many scientists have argued that the science classroom is no place for discussion of creationism. When I began teaching I did not teach creationism, as I focused instead on my areas of expertise. Over time it became clear that students had questions about creationism, and did not understand the difference between a scientific approach to knowledge and non-scientific approaches. This led me to wonder whether ignoring supernatural views allowed them to remain as viable ‘alternatives’ to scientific hypotheses, in the minds of students. Also, a psychology class is an ideal place to discuss not only the scientific method but also the cognitive errors associated with non-science views. I began to explain creationism in my classes, and to model the scientific thought process that leads to a rejection of creationism. My approach is consistent with research that demonstrates that teaching content alone is insufficient for students to develop critical thinking and my admittedly anecdotal experience leads me to conclude that ‘teaching the controversy’ has benefits for science students.

2014-07-01

Full Text Available An effective teacher is defined as someone who achieves goals which either directly or indirectly focus on the learning of their students (Anderson, 1991. It goes without saying that, what can lead to a change in the behavior and learning  of the pupils is effective teaching, not a mere transmitting of knowledge. It is important to know how teachers define effective teaching and what factors they consider the most important in the course of being an efficient and successful teacher. Although many studies have investigated the issue of effective teaching in past, to the best of the researchers’ knowledge no study have investigated the factors affecting teachers’ willingness to teach effectively. This study focused on the Iranian EFL teachers’ attitude toward effectual teaching. Thirty five teachers participated in this study through filling a validated and piloted questionnaire. The results indicated that most of the teachers thought that an effective teacher tries to encourage pupil participation and gets all the students involved. The results further depicted, “Teachers’ beliefs and previous experience” was the top selected factor leading to (ineffective teaching among the subjects. The findings of this study can have important implications for teacher educators and also EFL teachers themselves.

2018-03-01

A variety of the available time to react (ATR) has been utilised to study knee biomechanics during reactive jump-landing tasks. The purpose was to quantify knee kinematics and kinetics during a jump-land-jump task of three possible directions as the ATR was reduced. Thirty-four recreational athletes performed 45 trials of a jump-land-jump task, during which the direction of the second jump (lateral, medial or vertical) was indicated before they initiated the first jump, the instant they initiated the first jump, 300 ms before landing, 150 ms before landing or at the instant of landing. Knee joint angles and moments close to the instant of landing were significantly different when the ATR was equal to or more than 300 ms before landing, but became similar when the ATR was 150 ms or 0 ms before landing. As the ATR was decreased, knee moments decreased for the medial jump direction, but increased for the lateral jump direction. When the ATR is shorter than an individual's reaction time, the movement pattern cannot be pre-planned before landing. Knee biomechanics are dependent on the timing of the signal and the subsequent jump direction. Precise control of timing and screening athletes with low ATR are suggested.

Eidenberger, Horst

2003-12-01

This paper describes how the web standards Synchronized Multimedia Integration Language (SMIL) and Scalable Vector Graphics (SVG) are used in teaching at the Vienna University of Technology. SMIL and SVG are used in courses on multimedia authoring. Didactically, the goal is to teach students how to use media objects and timing concepts to build interactive media applications. Additionally, SMIL is applied to generate multimedia content from a database using a content management system. The paper gives background information on the SMIL and SVG standards and sketches how teaching multimedia is organized at the Vienna University of Technology. Courses from the summer term 2003 are described and illustrated in two case studies. General design problems of SMIL-based presentations are modelled as patterns. Additionally, suggestions for improvement in the standards are given and shortcomings of existing user agents are summarized. Our conclusion is that SMIL and SVG are very well suited for teaching multimedia. Currently, the main problem is that all existing SMIL players lack some properties desired for teaching applications (stability, correctness, etc.).

Yao, Lei; Yung, Ka Yi; Cheung, Maurice C; Chodavarapu, Vamsy P; Bright, Frank V

2011-01-01

We describe a Complementary Metal-Oxide Semiconductor (CMOS) Direct Time Interval Measurement (DTIM) Integrated Circuit (IC) to detect the decay (fall) time of the luminescence emission when analyte-sensitive luminophores are excited with an optical pulse. The CMOS DTIM IC includes 14 × 14 phototransistor array, transimpedance amplifier, regulated gain amplifier, fall time detector, and time-to-digital convertor. We examined the DTIM system to measure the emission lifetime of oxygen-sensitive luminophores tris(4,7-diphenyl-1, 10-phenanthroline) ruthenium(II) ([Ru(dpp)(3)](2+)) encapsulated in sol-gel derived xerogel thin-films. The DTIM system fabricated using TSMC 0.35 μm process functions to detect lifetimes from 4 μs to 14.4 μs but can be tuned to detect longer lifetimes. The system provides 8-bit digital output proportional to lifetimes and consumes 4.5 mW of power with 3.3 V DC supply. The CMOS system provides a useful platform for the development of reliable, robust, and miniaturized optical chemical sensors.

Asymptotic analysis of blood flow in stented arteries: time dependency and direct simulations***

Directory of Open Access Journals (Sweden)

Pichon Gostaf Kirill

2010-12-01

Full Text Available This work aims to extend in two distinct directions results recently obtained in [10]. In a first step we focus on the possible extension of our results to the time dependent case. Whereas in the second part some preliminary numerical simulations aim to give orders of magnitudes in terms of numerical costs of direct 3D simulations. We consider, in the first part, the time dependent rough problem for a simplified heat equation in a straight channel that mimics the axial velocity under an oscillating pressure gradient. We derive first order approximations with respect to ϵ, the size of the roughness. In order to understand the problem and set up correct boundary layer approximations, we perform a time periodic fourier analysis and check that no frequency can interact with the roughness. We show rigorously on this toy problem that the boundary layers remain stationary in time (independent on the frequency number. Finally we perform numerical tests validating our theoretical approach. In the second part, we determine actual limits, when running three-dimensional blood flow simulations of the non-homogenized stented arteries. We solve the stationary Stokes equations for an artery containing a saccular aneurysm. Consecutive levels of uniform mesh refinement, serve to relate spatial resolution, problem scale, and required computation time. Test computations are presented for femoral side aneurysm, where a simplified ten-wire stent model was placed across the aneurysm throat. We advocate the proposed stent homogenization model, by concluding that an actual computation power is not sufficient to run accurate, direct simulations of a pulsatile flow in stented vessels.

Discourses and Practices in Teaching Methods and Assessment

Full Text Available Translating the purposes of education into practice is particularly challenging for those who are new or have recently entered academia. By reflecting on my first years of teaching in higher education, I discuss two key aspects of my teaching practice: shifts in choice of teaching methods and a critique of different forms of assessment. Through the discussion, I argue that a teacher needs to be reflective on both these aspects and that such reflection needs to be carried out so that the student develops into a “self-directing,” “self-monitoring,” and “self-correcting” individual. At the end of the discussion, the relevance of a “project-based learning” approach starts to become significant in taking my pedagogical practice forward.

The status of bedside teaching in the United Kingdom: the student perspective

Directory of Open Access Journals (Sweden)

Jones P

2015-06-01

Full Text Available Patrick Jones, Bhavan Prasad Rai Department of Surgery, Ninewells Hospital, Dundee, UK Purpose: Bedside teaching holds a strong tradition as a key-learning platform for clinical examination in the basic medical clerkship. There is a growing body of literature expressing concern for its witnessed decline in medical school curricula. However, the views of students toward this patient-centered cornerstone in surgical education remain under-reported. The purpose of this study was to gain a nationwide perspective on bedside teaching according to medical students in the United Kingdom. Materials and methods: An adapted Delphi method was employed to formulate the question series as part of a multi-step process including a pilot study, which was used to construct this survey. The target population was medical undergraduates in the United Kingdom and participants were recruited via social media. Outcomes assessed included exposure to bedside teaching, perceived benefits of clinical simulation, and junior doctors as clinical teachers. Barriers to clinical examination were also evaluated. Results: Overall, 368 completed surveys were received (completion rate 98.9%. Final year students were significantly more likely to report receiving insufficient bedside teaching (P<0.01. Seventy-eight percent of the study group agreed that clinical simulation is a good learning tool for clinical examination. Seventy percent of students felt junior doctors were as able as senior doctors to teach. Lack of confidence was identified as the commonest barrier to overcome when examining patients and two-thirds of students felt they burdened patients during bedside teaching. Conclusion: This prospective study confirms the exposure deficit, which medical students experience in bedside teaching. The junior doctor represents a dynamic clinical teacher in the face of working time directives. Peer learning is a novel solution to such pressures. Work is needed to re-establish the

Dental schools in the United Kingdom are becoming increasingly reliant on the services of part-time teachers to deliver the clinical educational component of the dental course. Their background is predominantly from general dental practice but the opportunities to progress in the system are limited. The aim of this study was to ascertain the views and perceptions of such teachers at a dental school. An anonymous, non-incentivised online survey was used to obtain both qualitative and quantitative views of the part timers. The department has n = 40 part-time teachers and there was a response rate of 78%. Overall 73% were satisfied with their current teaching position, whereas the remaining 27% of teachers were seeking higher rewards both in terms of recognition and status. This study demonstrated the need for formal teaching skills and training to be made available to part-time clinical teachers. Allied to this is the requirement for a clearly defined and achievable career pathway.

Teaching meta-analysis using MetaLight

Directory of Open Access Journals (Sweden)

Thomas James

2012-10-01

Full Text Available Abstract Background Meta-analysis is a statistical method for combining the results of primary studies. It is often used in systematic reviews and is increasingly a method and topic that appears in student dissertations. MetaLight is a freely available software application that runs simple meta-analyses and contains specific functionality to facilitate the teaching and learning of meta-analysis. While there are many courses and resources for meta-analysis available and numerous software applications to run meta-analyses, there are few pieces of software which are aimed specifically at helping those teaching and learning meta-analysis. Valuable teaching time can be spent learning the mechanics of a new software application, rather than on the principles and practices of meta-analysis. Findings We discuss ways in which the MetaLight tool can be used to present some of the main issues involved in undertaking and interpreting a meta-analysis. Conclusions While there are many software tools available for conducting meta-analysis, in the context of a teaching programme such software can require expenditure both in terms of money and in terms of the time it takes to learn how to use it. MetaLight was developed specifically as a tool to facilitate the teaching and learning of meta-analysis and we have presented here some of the ways it might be used in a training situation.

The Pedagogical Orientations of South African Physical Sciences Teachers Towards Inquiry or Direct Instructional Approaches

Ramnarain, Umesh; Schuster, David

2014-08-01

In recent years, inquiry-based science instruction has become widely advocated in science education standards in many countries and, hence, in teacher preparation programmes. Nevertheless, in practice, one finds a wide variety of science instructional approaches. In South Africa, as in many countries, there is also a great disparity in school demographic situations, which can also affect teaching practices. This study investigated the pedagogical orientations of in-service physical sciences teachers at a diversity of schools in South Africa. Assessment items in a Pedagogy of Science Teaching Test (POSTT) were used to identify teachers' science teaching orientations, and reasons for pedagogical choices were probed in interviews. The findings reveal remarkable differences between the orientations of teachers at disadvantaged township schools and teachers at more privileged suburban schools. We found that teachers at township schools have a strong `active direct' teaching orientation overall, involving direct exposition of the science followed by confirmatory practical work, while teachers at suburban schools exhibit a guided inquiry orientation, with concepts being developed via a guided exploration phase. The study identified contextual factors such as class size, availability of resources, teacher competence and confidence, time constraints, student ability, school culture and parents' expectations as influencing the methods adopted by teachers. In view of the recent imperative for inquiry-based learning in the new South African curriculum, this study affirms the context specificity of curriculum implementation (Bybee 1993) and suggests situational factors beyond the curriculum mandate that need to be addressed to achieve successful inquiry-based classroom instruction in science.

Using Office Simulation Software in Teaching Computer Literacy Using Three Sets of Teaching/Learning Activities

Directory of Open Access Journals (Sweden)

Azad Ali

2016-05-01

Full Text Available The most common course delivery model is based on teacher (knowledge provider - student (knowledge receiver relationship. The most visible symptom of this situation is over-reliance on textbook’s tutorials. This traditional model of delivery reduces teacher flexibility, causes lack of interest among students, and often makes classes boring. Especially this is visible when teaching Computer Literacy courses. Instead, authors of this paper suggest a new active model which is based on MS Office simulation. The proposed model was discussed within the framework of three activities: guided software simulation, instructor-led activities, and self-directed learning activities. The model proposed in the paper of active teaching based on software simulation was proven as more effective than traditional.

Full Text Available Teaching overseas has always been a great opprotunity for academic and social development. Teachers who have international experiences stand a better chance of not only developing their teaching skills, communication skills and classroom management but also learning new languages and about other cultures. Teaching abroad can help teachers promote their skills for efficiency and effectiveness. It is important to stress that teachers with international experience can teach effectively and can contribute to the achievement of their students more. This paper focuses on five reasons why teachers prefer teaching overseas.

The existence of abnormal connectivity patterns between resting state networks in neuropsychiatric disorders, including Autism Spectrum Disorder (ASD), has been well established. Traditional treatment methods in ASD are limited, and do not address the aberrant network structure. Using real-time fMRI neurofeedback, we directly trained three brain nodes in participants with ASD, in which the aberrant connectivity has been shown to correlate with symptom severity. Desired network connectivity patterns were reinforced in real-time, without participants' awareness of the training taking place. This training regimen produced large, significant long-term changes in correlations at the network level, and whole brain analysis revealed that the greatest changes were focused on the areas being trained. These changes were not found in the control group. Moreover, changes in ASD resting state connectivity following the training were correlated to changes in behavior, suggesting that neurofeedback can be used to directly alter complex, clinically relevant network connectivity patterns.

Johansson, Ellen; Holmin, Tobias E; Johansson, Bengt R; Braide, Magnus

2018-02-14

Peer-assisted learning has gained momentum in a variety of disciplines, including medical education. In Gothenburg, Sweden, medical students who have finished their compulsory anatomy courses have the option of working as teaching assistants (TAs). Teaching assistants provide small group teaching sessions as a complement to lectures given by faculty. Previously, TAs were left to handle the role as junior teachers by themselves, but since 2011, a continuation course in anatomy has been developed with the aim of providing the TAs better anatomy knowledge and guidance for teaching. The course was designed to comprise 7.5 ECTS credits (equivalent to 5 weeks of full-time studies), and today all TAs are required to take this course before undertaking their own teaching responsibilities. This study aims to compare course evaluations of TA teaching before and after the introduction of the anatomy continuation course, in order to understand how students perceived teaching performed by self-learned versus trained TAs. The results of this study demonstrate that there was a trend towards better teaching performed by trained TAs. The variability in rankings decreased significantly after the introduction of the continuation course. This was mainly due to an improvement among the TAs with the lowest levels of performance. In addition to comparing student rankings, TAs were interviewed regarding their experiences and perceptions within the continuation course. The course was generally positively regarded. The TAs described a sense of cohesion and appreciation since the institute invested in a course dedicated specifically for them.

Performing T-tests to Compare Autocorrelated Time Series Data Collected from Direct-Reading Instruments.

Science.gov (United States)

O'Shaughnessy, Patrick; Cavanaugh, Joseph E

2015-01-01

Industrial hygienists now commonly use direct-reading instruments to evaluate hazards in the workplace. The stored values over time from these instruments constitute a time series of measurements that are often autocorrelated. Given the need to statistically compare two occupational scenarios using values from a direct-reading instrument, a t-test must consider measurement autocorrelation or the resulting test will have a largely inflated type-1 error probability (false rejection of the null hypothesis). A method is described for both the one-sample and two-sample cases which properly adjusts for autocorrelation. This method involves the computation of an "equivalent sample size" that effectively decreases the actual sample size when determining the standard error of the mean for the time series. An example is provided for the one-sample case, and an example is given where a two-sample t-test is conducted for two autocorrelated time series comprised of lognormally distributed measurements.

Silverman, M. P.

1995-06-01

An account is given of the instruction of university-level introductory physics courses according to an educational framework in which (1) curiosity-driven inquiry is recognized as an essential activity of both science and science teaching; (2) the principal role of the instructor is to provide students the incentive to learn science through their pursuit of personally meaningful questions; (3) the commission of errors is regarded as a natural concomitant to learning and is not penalized; (4) emphasis is placed on laboratory investigations that foster minimally restrictive free exploration rather than prescriptive adherence to formal procedure; (5) research skills are developed through out-of-class projects that involve literature search, experiment, and the modeling of real-world physical phenomena: (6) the precise and articulate use of language is regarded as seminal to communication in science (as it is in the humanities) and is promoted through activities that help develop written and oral language skills; (7) the evaluation of student performance is based on a portfolio of accomplished work rather than on the outcome of formal testing.

See, Do, Teach? A Review of Contemporary Literature and Call to Action for Communication Skills Teaching in Urology.

To assess the current state of published literature on communication skills teaching in urology to inform future directions for research and teaching. Excellent patient-physician communication skills increase understanding of medical conditions, facilitate shared decision-making regarding treatment planning, improve clinical outcomes, and decrease lawsuits. Surgical and procedure-based subspecialties, including urology, have generally been slow to incorporate formal communication skills teaching into curricula for postgraduate trainees. We performed a PubMed literature search using multiple keywords, selecting and reviewing articles published in English, and addressing 1 of 3 domains (curriculum development, teaching methods, and assessment methods) of communication skills teaching. The distribution of articles within the urology-specific literature was compared with that of procedure-based specialties as a whole. Eight articles were found in the urology literature, and 24 articles were found in other procedure-based specialties. Within the urology-specific literature, all 8 articles (100%) acknowledged the need for communication curriculum development, 1 article (12.5%) described how communication skills were taught, and 1 article (12.5%) discussed how communication skills were assessed. Fewer articles in other procedure-based specialties acknowledged the need to develop curricula (29.2%, P = .0007) but were equally likely to discuss communication skills teaching (37.5%, P = .63) and assessment (33.3%, P = .73). Orthopedic surgery is the only surgical subspecialty with ongoing, adaptable, formal training for physicians. Most current publications addressing communication skills in procedure-based specialties are specialty specific and focus on only 1 of the 3 communication domains. Opportunities exist to share information and to create more integrated models to teach communication skills in urology. Copyright © 2018 Elsevier Inc. All rights reserved.

To survey practice and opinion regarding school-based teaching of communication skills, to summarise relevant research evidence from physiotherapy and beyond, to reflect on practice in light of evidence, and to propose associated recommendations. Survey using customised questionnaires. Basic descriptive statistical analysis and thematic content analysis were used. The results were compared with evidence from systematic reviews to derive recommendations. SURVEY PARTICIPANTS AND SETTING: Educators in all UK centres delivering physiotherapy qualifying programmes in 2006. A response rate of 69% was achieved. The majority of respondents reported delivering communication-specific modules. Lecturing was common, and more experiential methods were also used. Assessment was mainly by written work. Educators commented on challenges and strategies involved in student engagement, provision of authentic experiences, availability of teaching time and expertise, and physiotherapy-specific teaching resources. Evidence from allied health profession, medical and nursing education research emphasises the importance of experiential teaching, formative feedback, observational assessment and a substantial evidence base on which to ground course content. In physiotherapy, the latter is emerging but incomplete. There are also gaps in direct evidence about advantages or otherwise of stand-alone modules and benefits of pre-qualification communication training. Evidence suggests that effective training requires substantial teaching time, expertise and a body of empirical research on specific communication practices and their effects. Curriculum designers and educators should endeavour to maximise the degree to which training in this area is experiential, provide training when students have already had some contact with patients, and assess students by observation if at all possible. Due to gaps in the evidence, some important questions about optimal practice remain unanswered.

Online education has become a key instructional delivery method in nursing education; however, limited understanding exists about what it is like to teach online. The aim of this study was to uncover the experience of teaching online in nursing education. The sample for this phenomenological study included 14 nursing faculty who completed at least 50% of their teaching workload assignment in fully online courses in baccalaureate, master's, or doctoral nursing programs. Data were collected through the use of a demographic questionnaire and personal interviews. Four themes emerged from the data: (a) Looking at a Lot of Moving Parts, (b) Always Learning New Things, (c) Going Back and Forth, and (d) Time Is a Blessing and a Curse. Online teaching in nursing education differs from traditional classroom teaching in a variety of ways. Policies and guidelines that govern faculty teaching should encompass the identified intricacies of online teaching. [J Nurs Educ. 2017;56(6):343-349.]. Copyright 2017, SLACK Incorporated.

The 2015 American College of Clinical Pharmacy (ACCP) Educational Affairs Committee was charged with developing a self-assessment guide for residency programs to quantitatively and qualitatively evaluate the outcomes of resident teaching curricula. After extensively reviewing the literature, the committee developed assessment rubrics modeled after the 2013 ACCP white paper titled "Guidelines for Resident Teaching Experiences" and the revised American Society of Health-System Pharmacists (ASHP) 2014 accreditation standards for PGY1 residencies, which place greater emphasis on the teaching and learning curriculum (TLC) than the previous accreditation standards. The self-assessment guide developed by the present committee can serve as an assessment tool for both basic and expanded TLCs. It provides the criteria for program goals, mentoring, directed readings with topic discussions, teaching experiences, and assessment methodology. For an expanded TLC, the committee has provided additional guidance on developing a teaching philosophy, becoming involved in interactive seminars, expanding teaching experiences, developing courses, and serving on academic committees. All the guidelines listed in the present paper use the measures "not present," "developing," and "well developed" so that residency program directors can self-assess along the continuum and identify areas of excellence and areas for improvement. Residency program directors should consider using this new assessment tool to measure program quality and outcomes of residency teaching experiences. Results of the assessment will help residency programs focus on areas within the TLC that will potentially benefit from additional attention and possible modification. © 2016 Pharmacotherapy Publications, Inc.

Teaching communication skills: beyond wishful thinking.

Junod Perron, Noelle; Sommer, Johanna; Louis-Simonet, Martine; Nendaz, Mathieu

2015-01-01

Communication skills tend to decline with time unless they are regularly recalled and practiced. However, most medical schools still deliver clinical communication training only during pre-clinical years although the clinical environment is considered to be ideal for acquiring and teaching clinical communication. The aim of this article is to review the barriers that prevent communication skills teaching and training from occurring in clinical practice and describe strategies that may help enhance such activities. Barriers occur at several levels: students, junior doctors and clinical supervisors sometimes have negative attitudes towards communication training; structured training in communication skills is often insufficient; clinical supervisors behave as poor role models and lack effective communication and teaching skills; finally, there are organisational constraints such as lack of time, competing priorities, weak hierarchy support and lack of positive incentives for using, training or teaching good communication skills in clinical practice. Given the difficulty of assessing transfer of communication skills in practice, only few studies describe successful educational interventions. In order to optimise communication skills learning in practice, there is need to: (1.) modify the climate and structure of the working environment so that that use, training and teaching of good communication skills in clinical practice becomes valued, supported and rewarded; (2.) extend communication skills training to any field of medicine; (3.) provide regular structured trainings and tailor them to trainees' needs. Practical implications of such findings are discussed at the end of this review.

In the time of advancing quality education, emotion education has been paid more and more attention. English teaching is both language teaching progress and emotional communication progress. Therefore, emotional education is extremely important and indispensable in vocational school classroom teaching. However, the current application of vocational school emotional education in English classroom teaching is still relatively weak. Based on the theory of emotional education, this paper attempts to explore the methods and strategies of applying emotional education in vocational school English classroom teaching. It has important theoretical significance on promoting the comprehensive development of the vocational school students, improving English teaching effect, promoting the healthy and sustainable development of the vocational school education, and enriching and developing the emotional teaching psychology and cognitive psychology theory.

2018-05-01

This research aims to investigate the enhancement of students’ mathematical self- efficacy through teaching with metacognitive scaffolding approach. This research used a quasi- experimental design with pre-post respon control. The subjects were pre-service elementary school teachers in a state university in Bandung. In this study, there were two groups: experimental and control groups. The experimental group consists of 60 students who acquire teaching mathematics under metacognitive approach, while the control group consists of 58 students who acquire teaching mathematics under direct approach. Students were classified into three categories based on the mathematical prior ability, namely high, middle, and low. Data collection instruments consist of mathematical self-efficacy instruments. By using mean difference test, two conclusions of the research: (1) there is a significant difference in the enhancement of mathematical self-efficacy between the students who attended the course under metacognitive scaffolding approach and students who attended the course under direct approach, and (2) there is no significant interaction effect of teaching approaches and ability level based on the mathematical prior ability toward enhancement of students’ mathematical self-efficacy.

Summer is almost here (at least for those of us who teach semesters). Many of us are taking a well-deserved break to spend time with our families, conduct research, travel, and myriad other activities. Some of us, however, will be teaching summer school. For those of us lucky enough to be teaching this summer, we have one suggestion: Be bold! Summer is the ideal time to try something new with your teaching. We have known for some time that alternative pedagogies and engaging teaching strategies can be more effective than traditional lectures as student learning environments. However, even with headlines in The Washington Post proclaiming that the lecture is dead,2 inroads of physics education research-based curricula have been slow to diffuse into the classrooms for the greater population of college physics instructors.3 Many instructors of traditional physics courses see the use of research-based instructional strategies (RBIS) as desirable but risky and time consuming.3 Assuming a traditional physics course structure, both the where and the when each component takes place can also limit the types of engaging pedagogies used.4

2015-01-01

The purpose of this study was to examine current approaches and challenges to teaching ethics in entry-level Canadian physiotherapy (PT) and occupational therapy (OT) programs. Educators responsible for teaching ethics in the 28 Canadian PT and OT programs (n = 55) completed an online survey. The quantity of ethics teaching is highly variable, ranging from 5 to 65 h. Diverse obstacles to ethics teaching were reported, relating to the organization and structure of academic programs, student issues and the topic of ethics itself. Specific challenges included time constraints, large class sizes, a lack of pedagogical tools adapted to teaching this complex subject, a perceived lack of student interest for the subject and a preference for topics related to clinical skills. Of note, 65% of ethics educators who participated in the survey did not have any specialized training in ethics. Significant cross-program variation in the number of hours dedicated to ethics and the diversity of pedagogical methods used suggests that there is little consensus about how best to teach ethics. Further research on ethics pedagogy in PT and OT programs (i.e. teaching and evaluation approaches and effectiveness of current ethics teaching) would support the implementation of more evidence-based ethics education. Implications for Rehabilitation Ethics educators in Canadian PT and OT programs are experimenting with diverse educational approaches to teach ethical reasoning and decision-making to students, including lectures, problem-based learning, directed readings, videos, conceptual maps and clinical elective debriefing, but no particular method has been shown to be more effective for developing ethical decision-making/reasoning. Thus, research on the effectiveness of current methods is needed to support ethics educators and programs to implement evidence-based ethics education training. In our survey, 65% of ethics educators did not have any specialized training in ethics. Ensuring

Pre-Service Teachers Methods of Teaching Science

Full Text Available The study described the teaching methods used by pre-service teachers in Science. It focused on the strategies, techniques, materials, innovative methods and pattern of teaching science used by the pre-service teachers as described in their lesson plans. The qualitative and quantitative design was used in the study. The books, teacher hand-outs from classroom lectures were the sources of methods, strategies and techniques. The chalkboard and self-made drawings and charts were the materials often used. Conventional methods like lecture, open class discussion and demonstration were commonly employed. The strategies included group discussion, use of motivating questions and stories to arouse the interest of students. The direct eye contact, body expressions, jokes and news/trivia were frequent techniques. Integration of values in the lesson became less as the year level increases. The pattern of teaching drawn followed the formal style: I Objectives, II Subject matter, III Learning Tasks, IV Synthesis of the lesson, V Assessment and VI Enrichment. The conventional method and pattern of teaching by the pre-service teachers of PSU suggest that students in the College of Teacher Education should be trained to be more innovative and open in trying out more advanced teaching methods. Furthermore, PSU science pre-service teachers should use methods which can develop higher order thinking skills among high school students.

Many schools rely upon community preceptors for office-based education of medical students. These preceptors struggle to balance clinical care with the learning needs of students. We aim to gain a deeper understanding of the teaching rewards and challenges of current community preceptors. Five schools' family medicine clerkship directors conducted in-depth interviews of two exemplary preceptors at each of their programs. Following qualitative analysis of the interviews, three directors conducted one focus group at their school. The individual and group interviews were recorded, transcribed, and analyzed using grounded theory. Exemplary community preceptors described strategies to improve the learning environment and specific teaching approaches. Well-known teaching strategies such as role modeling, adjusting instruction to the learner's needs, and selecting patients appropriate for a specific student were used. They also described newer techniques such as co-learning and integrating technology, for example, accessing online, current practice guidelines together with the student. They detailed challenges to teaching, including time constraints and too much content to cover and provided advice about teaching tools. While challenged by clinical demands, preceptors enjoyed teaching and found it rewarding. They used time-proven teaching strategies as well as technology and online resources to facilitate ambulatory teaching. Community preceptors continue to struggle to integrate learners and the priorities of the medical school curriculum into the clinical environment. Further development of electronic tools and other resources to support the teaching needs of preceptors may contribute to learning and help minimize preceptor burden.

The student experience of applied equivalence-based instruction for neuroanatomy teaching.

Greville, W James; Dymond, Simon; Newton, Philip M

2016-01-01

Esoteric jargon and technical language are potential barriers to the teaching of science and medicine. Effective teaching strategies which address these barriers are desirable. Here, we created and evaluated the effectiveness of stand-alone 'equivalence-based instruction' (EBI) learning resources wherein the teaching of a small number of direct relationships between stimuli (e.g., anatomical regions, their function, and pathology) results in the learning of higher numbers of untaught relationships. We used a pre and post test design to assess students' learning of the relations. Resources were evaluated by students for perceived usefulness and confidence in the topic. Three versions of the resources were designed, to explore learning parameters such as the number of stimulus classes and the number of relationships within these classes. We show that use of EBI resulted in demonstrable learning of material that had not been directly taught. The resources were well received by students, even when the quantity of material to be learned was high. There was a strong desire for more EBI-based teaching. The findings are discussed in the context of an ongoing debate surrounding 'rote' vs. 'deep' learning, and the need to balance this debate with considerations of cognitive load and esoteric jargon routinely encountered during the study of medicine. These standalone EBI resources were an effective, efficient and well-received method for teaching neuroanatomy to medical students. The approach may be of benefit to other subjects with abundant technical jargon, science and other areas of medicine.

To analyze the fair market value impact of GME payment on resident teaching efforts in our pediatric intensive care unit (PICU). Cost-accounting model, developed from a 1-year retrospective, descriptive, single-institution, longitudinal study, applied to physician teachers, residents, and CMS. Sixteen-bed PICU in a freestanding, university-affiliated children's teaching hospital. Pediatric critical care physicians, second-year residents. Cost of physician opportunity time; CMS investment return; the teaching physicians' investment return; residents' investment return; service balance between CMS and teaching service investment margins; economic balance points; fair market value. GME payments to our hospital increased 4.8-fold from 577 886 dollars to 2 772 606 dollars during a 1-year period. Critical care physicians' teaching opportunity cost rose from 250 097 dollars to 262 215 dollars to provide 1523 educational hours (6853 relative value units). Residents' net financial value for service provided to the PICU rose from 245 964 dollars to 317 299 dollars. There is an uneven return on investment in resident education for CMS, critical care physicians, and residents. Economic balance points are achievable for the present educational efforts of the CMS, critical care physicians, and residents if the present direct medical education payment increases from 29.38% to 36%. The current CMS Health Resources and Services Administration Children's Hospitals GME Payment Program produces uneven investment returns for CMS, critical care physicians, and residents. We propose a cost-accounting model, based on perceived production capability measured in relative value units and available GME funds, that would allow a clinical service to balance and obtain a fair

A computerized three-dimensional (3D) neuroanatomy teaching tool was developed for training medical students to identify subcortical structures on a magnetic resonance imaging (MRI) series of the human brain. This program allows the user to transition rapidly between two-dimensional (2D) MRI slices, 3D object composites, and a combined model in which 3D objects are overlaid onto the 2D MRI slices, all while rotating the brain in any direction and advancing through coronal, sagittal, or axial planes. The efficacy of this tool was assessed by comparing scores from an MRI identification quiz and survey in two groups of first-year medical students. The first group was taught using this new 3D teaching tool, and the second group was taught the same content for the same amount of time but with traditional methods, including 2D images of brain MRI slices and 3D models from widely used textbooks and online sources. Students from the experimental group performed marginally better than the control group on overall test score (P = 0.07) and significantly better on test scores extracted from questions involving C-shaped internal brain structures (P teaching tool is an effective way to train medical students to read an MRI of the brain and is particularly effective for teaching C-shaped internal brain structures. © 2015 American Association of Anatomists.

Bedside teaching is defined as any teaching in the presence of patient and is the core teaching strategy during the clinical years of a medical student. Although it is considered the most effective method to teach clinical and communication skills but its quality is deteriorating with the passage of time. The objective of this study is to explore faculty's perceptions about bedside teaching. This study was conducted in clinical disciplines of Ayub Medical College and hospital Abbottabad, Pakistan from January 2012 to July 2012. Pragmatic paradigm was selected to gather both quantitative and qualitative information. Data was collected sequentially to validate findings. Perceptions of all professors of clinical subjects about bed side teaching were recorded on a close-ended structured questionnaire. Then in-depth interviews were taken from 5 professors using an open ended questionnaire. Quantitative data was analysed using, SPSS-16. Qualitative research data was analysed through content analysis. Out of 20 professors of clinical departments 18 agreed to respond to the questionnaire assessing their perceptions about bed side teaching. Non-existence of bedside teaching curriculum, lack of discipline in students and faculty, lack of accountability, poor job satisfaction and low salary were identified as major factors responsible for decline in quality of bedside teaching. Most of them advocated that curriculum development, planning bedside teaching, implementation of discipline and accountability, improved job satisfaction and performance based promotions will improve quality of clinical teaching. Curriculum development for bedside teaching, institutional discipline, application of best planning strategies, performance based appraisal of faculty and good job satisfaction can make bedside teaching an effective instructional tool.

Influence of Short-time Oxidation on Corrosion Properties of Directionally Solidified Superalloys with Different Orientations

2016-07-01

Full Text Available In order to investigate the corrosion performance on intersecting and longitudinal surfaces of unoxidized and oxidized directionally solidified superalloys, Ni-base directionally solidified superalloy DZ125 and Co-base directionally solidified superalloy DZ40M were selected. Oxidation behavior on both alloys with different orientations was investigated at 1050℃ at different times, simulating the oxidation process of vanes or blades in service; subsequent electrochemical performance in 3.5%NaCl aqueous solution was studied on two orientations of unoxidized and oxidized alloys, simulating the corrosion process of superalloy during downtime. The results show that grain boundaries and sub-boundaries of directionally solidified superalloys are susceptible to corrosion and thus longitudinal surface with lower area fraction of grain boundaries has higher corrosion resistance. Compared to intersecting surface of alloys, the structure of grain boundaries of longitudinal surface is less conducive to diffusion and thus the oxidation rate on longitudinal surface is lower. Formation of oxide layers on alloys after short-time oxidation provides protective effect and enhances the corrosion resistance.

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.

On-line radiation teaching materials using IT technology

International Nuclear Information System (INIS)

Inoue, Hiroyoshi

2005-01-01

We developed the on-line radiation teaching materials using the Internet, in order to provide the teaching support materials of atomic power and radiation educations in on-school study, as well as to create the complementary study system in off-school study. The themes of teaching materials were selected from requests by teachers. In the case of an elementary school, the teaching material 'an environmental problem and atomic power' was created as the aggregate of each content for study without boundary between subjects. The teaching material 'medical treatment and radiation' was created for junior high school students to raise the individual knowledge. In the case of a high school, the teaching material nucleus and radiation' was prepared to supplement the physical study of students. The on-line teaching materials were tried to 300 junior high school and high school students, 68% of students answered that the teaching material is effective to understand atomic power and radiation, though 17% answered they were not effective. Although there are problems to prepare IT learning equipments and learning follow-up system in the material, it is suggested that the on-line teaching materials will provide the novel learning system including debates for the study. This method has no limitation of time and place. (author)

2012-01-01

Audiovisual learning resources have become valuable adjuncts to formal teaching in surgical training. This report discusses the process and challenges of preparing an audiovisual teaching tool for laparoscopic cholecystectomy. The relative value in surgical education and training, for both the creator and viewer are addressed. This audiovisual teaching resource was prepared as part of the Master of Surgery program at the University of Sydney, Australia. The different methods of video production used to create operative teaching tools are discussed. Collating and editing material for an audiovisual teaching resource can be a time-consuming and technically challenging process. However, quality learning resources can now be produced even with limited prior video editing experience. With minimal cost and suitable guidance to ensure clinically relevant content, most surgeons should be able to produce short, high-quality education videos of both open and minimally invasive surgery. Despite the challenges faced during production of audiovisual teaching tools, these resources are now relatively easy to produce using readily available software. These resources are particularly attractive to surgical trainees when real time operative footage is used. They serve as valuable adjuncts to formal teaching, particularly in the setting of minimally invasive surgery. Copyright © 2012 Association of Program Directors in Surgery. Published by Elsevier Inc.

Full Text Available Developing learners’ writing skills has been of concern for a long time in education. Students studying English in our educational institutions have been found to face problems mainly in writing, making them unable to cope with the institution’s literacy expectations. However, these students may be able to develop writing skills significantly with positive instructional attitudes towards the errors they make and awareness on the teachers’ part of learner problems. That is why they should improve classroom writing instruction to address the serious problem of students writing difficult. Teaching strategies has shown a dramatic effect on the quality of students’ writing. Strategy instruction involves explicitly and systematically teaching steps necessary to use strategies independently. The following table will explain the above ideas.

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.

The Effect of the Rolling Direction, Temperature, and Etching Time on the Photochemical Machining of Monel 400 Microchannels

Full Text Available The present paper describes the effect of the rolling direction on the quality of microchannels manufactured using photochemical machining (PCM of Monel 400. Experiments were carried out to fabricate microchannels along and across the rolling direction to investigate the effect of the grain orientation on microchannel etching. The input parameters considered were channel width and rolling direction, whereas the depth of etch was the response parameters. Different channels of widths of 60, 100, 150, 200, and 250 μm were etched. The effects of the etching time and temperature of the etchant solution on the undercut and depth of the microchannels were studied. For good quality microchannels, the effects of spinning time, spinning speed, exposure time, and photoresist film strength were also taken into consideration. Optimized values of the above were used for the experimentation. The results show that the depth of etch of the microchannel increases more along the rolling direction than across the rolling direction. The channel width and depth are significantly affected by the etching time and temperature. The proposed study reports an improvement in the quality of microchannels produced using PCM.

Cross-Curricular Teaching: The Case of Mark Haddon’s The Curious Incident of the Dog in the Night-Time

Directory of Open Access Journals (Sweden)

2014-05-01

Full Text Available The knowledge learners acquire at school has to be applicable in practice to ensure their motivation for learning. Both cross-curricular and interdisciplinary teaching provide a meaningful way in which students can use the knowledge acquired in one context as the basis for learning in other contexts in and out of school. By using interdisciplinary teaching, the instructor can present the topics in a holistic manner: this approach therefore allows us to activate more of the learners’ senses and intelligences. Since Mathematics is one of the least liked subjects by our students, and English one of the favorite ones, the article will demonstrate how we can integrate activities addressing all types of intelligences in a language learning class to achieve the whole range of Bloom’s levels of educational objectives on the basis of a novel which includes a wealth of references to mathematics: The Curious Incident of the Dog in the Night-Time by Mark Haddon, which has recently been compulsory reading in all Slovene grammar school programs.

Delivering effective clinical pediatric communication skills training to undergraduate medical students is a distinct and important challenge. Pediatric-specific communication skills teaching is complex and under-researched. We report on the development of a scenario-based pediatric clinical communication skills program as well as students' assessment of this module. We designed a pediatric clinical communication skills program and delivered it five times during one academic year via small-group teaching. Students were asked to score the workshop in eight domains (learning objectives, complexity, interest, competencies, confidence, tutors, feedback, and discussion) using 5-point Likert scales, along with free text comments that were grouped and analyzed thematically, identifying both the strengths of the workshop and changes suggested to improve future delivery. Two hundred and twenty-one of 275 (80%) student feedback forms were returned. Ninety-six percent of students' comments were positive or very positive, highlighting themes such as the timing of teaching, relevance, group sizes, and the use of actors, tutors, and clinical scenarios. Scenario-based teaching of clinical communication skills is positively received by students. Studies need to demonstrate an impact on practice, performance, development, and sustainability of communications training.

Koka, Andre; Hagger, Martin S

2010-03-01

In the present study, we tested the effects of specific dimensions of perceived teaching behaviors on students' self-determined motivation in physical education. In accordance with the tenets of self-determination theory (Deci & Ryan, 1985, 2000), we expected the psychological needs for competence, autonomy, and relatedness would mediate these effects. Secondary school students (N=498) ages 12-17 years completed measures of perceived teaching behaviors for seven dimensions: (a) democratic behavior, (b) autocratic behavior (c) teaching and instruction, (d) situation consideration, (e) positive general feedback, (f) positive nonverbal feedback, and (h) negative nonverbal feedback. They also completed measures of perceived satisfaction for competence, autonomy, relatedness, and self-determined motivation. A path-analytic model revealed a positive, indirect effect of perceived positive general feedback on self-determined motivation. The effects of perceived autocratic behavior and negative nonverbal feedback were direct and negative, whereas the effects of teaching and instruction and situation consideration were direct and positive. Results suggest that feedback, situation consideration, and teaching and instruction are essential antecedents to self-determined motivation.

To study surgical teaching captured on film and analyze it at a fine level of detail to categorize physical teaching behaviors. We describe live, filmed, intraoperative nonverbal exchanges between surgical attending physicians and their trainees (residents and fellows). From the films, we chose key teaching moments and transcribed participants' utterances, actions, and gestures. In follow-up interviews, attending physicians and trainees watched videos of their teaching case and answered open-ended questions about their teaching methods. Using a grounded theory approach, we examined the videos and interviews for what might be construed as a teaching behavior and refined the physical teaching categories through constant comparison. We filmed 5 cases in the operating suite of a university teaching hospital that provides gynecologic surgical care. We included 5 attending gynecologic surgeons, 3 fellows, and 5 residents for this study. More than 6 hours of film and 3 hours of interviews were transcribed, and more than 250 physical teaching motions were captured. Attending surgeons relied on actions and gestures, sometimes wordlessly, to achieve pedagogical and surgical goals simultaneously. Physical teaching included attending physician-initiated actions that required immediate corollary actions from the trainee, gestures to illustrate a step or indicate which instrument to be used next, supporting or retracting tissues, repositioning the trainee's instruments, and placement of the attending physicians' hands on the trainees' hands to guide them. Attending physicians often voiced surprise at the range of their own teaching behaviors captured on film. Interrater reliability was high using the Cohen κ, which was 0.76 for the physical categories. Physical guidance is essential in educating a surgical trainee, may be tacit, and is not always accompanied by speech. Awareness of teaching behaviors may encourage deliberate teaching and reflection on how to innovate pedagogy

In this work, the effect of oversubscription is evaluated, via calling 2n, 3n, or 4n processes for n physical cores, on semi-direct MP2 energy and gradient calculations and RI-MP2 energy calculations with the cc-pVTZ basis using NWChem. Results indicate that on both Intel and AMD platforms, oversubscription reduces total time to solution on average for semi-direct MP2 energy calculations by 25-45% and reduces total energy consumed by the CPU and DRAM on average by 10-15% on the Intel platform. Semi-direct gradient time to solution is shortened on average by 8-15% and energy consumption is decreased by 5-10%. Linear regression analysis shows a strong correlation between time to solution and total energy consumed. Oversubscribing during RI-MP2 calculations results in performance degradations of 30-50% at the 4n level. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

Use of an orton-gillingham approach to teach a foreign language to dyslexic/learning-disabled students: Explicit teaching of phonology in a second language.

Science.gov (United States)

Sparks, R L; Ganschow, L; Kenneweg, S; Miller, K

1991-01-01

Recent research findings suggest that students who have difficulty learning a second language have weaknesses in oral and written native-language skills which affect their performance in the foreign-language classroom. These weaknesses involve understanding the phonological, syntactic, and semantic codes of language. Evidence suggests that dyslexic/learning-disabled and other "at risk" students who struggle in the second language classroom exhibit particular difficulty with the phonological and syntactic codes of the language. The Orton-Gillingham method, a multisensory, structured language approach which adheres to the direct and explicit teaching of phonology, is presented as an alternative to the "natural" communication approaches recently developed by foreign-language educators to teach a second language. A method for adapting this approach for teaching Spanish is described.

Teaching Using Immersion - Explaining Magnetism and Eclipses in a Planetarium Dome

Science.gov (United States)

Reiff, P. H.; Sumners, C.

2017-12-01

Previously we have shown that three-dimensional concepts are more readily learned in a three-dimensional context. Although VR headsets are growing in popularity, they only provide a quite limited field of view, and each person in a group may be viewing a different direction or a different time in the visualization. By using instead a fullsphere movie (VR360) in a planetarium dome instead of a headset, you can share the VR and specify which half of the sphere your audience is looking at. You can pause the movie, ask questions using a clicker system, display the results, and move on if the subject is mastered or explain if items are not understood. In this paper we have used a planetarium dome in its more traditional "hemisphere" mode to teach about magnetism (using our new show "Magnetism - Defending Our Planet, Defining the Cosmos" ) and pre/post testing to show how many concepts can be understood in a relatively short experience. We have identified 35 concepts that most high school students do NOT know about magnetism, and have done pre/post testing on students and teachers. Most students more than doubled the number of concepts that they were able to explain after watching the show just one time. We have also created a series of eclipse animations to teach about solar and lunar eclipses. These animations have been used in more than 500 planetarium theaters and used as part of several TV specials on the August 2017 eclipse. By teaching eclipses in a dome, the students correctly understand the three-dimensional geometry of the Earth and Moon orbits and the causes of eclipses.

Direct and inverse problems in dispersive time-of-flight photocurrent revisited

2017-10-01

Using the fact that the continuous time random walk (CTRW) scheme is a random process subordinated to a simple random walk under the operational time given by the number of steps taken by the walker up to a given time, we revisit the problem of strongly dispersive transport in disordered media, which first lead Scher and Montroll to introducing the power law waiting time distributions. Using a subordination approach permits to disentangle the complexity of the problem, separating the solution of the boundary value problem (which is solved on the level of normal diffusive transport) from the influence of the waiting times, which allows for the solution of the direct problem in the whole time domain (including short times, out of reach of the initial approach), and simplifying strongly the analysis of the inverse problem. This analysis shows that the current traces do not contain information sufficient for unique restoration of the waiting time probability densities, but define a single-parametric family of functions that can be restored, all leading to the same photocurrent forms. The members of the family have the power-law tails which differ only by a prefactor, but may look astonishingly different at their body. The same applies to the multiple trapping model, mathematically equivalent to a special limiting case of CTRW.

The Office of Instruction and Assessment at the University of Arizona currently offers a Certificate in College Teaching Program. The objective of this program is to develop the competencies necessary to teach effectively in higher education today, with an emphasis on learner-centered teaching. This type of teaching methodology has repeatedly shown to have superior effects compared to traditional teacher-centered approaches. The success of this approach has been proven in both short term and long term teaching scenarios. Students must actively participate in class, which allows for the development of depth of understanding, acquisition of critical thinking, and problem-solving skills. As optical science graduate students completing the teaching program certificate, we taught a recitation class for OPTI 370: Photonics and Lasers for two consecutive years. The recitation was an optional 1-hour long session to supplement the course lectures. This recitation received positive feedback and learner-centered teaching was shown to be a successful method for engaging students in science, specifically in optical sciences following an inquiry driven format. This paper is intended as a guide for interactive, multifaceted teaching, due to the fact that there are a variety of learning styles found in every classroom. The techniques outlined can be implemented in many formats: a full course, recitation session, office hours and tutoring. This guide is practical and includes only the most effective and efficient strategies learned while also addressing the challenges faced, such as formulating engaging questions, using wait time and encouraging shy students.

To measure the time needed to teach a series of martial arts techniques to proficiency. Fifteen volunteer subjects without any prior martial arts or self-defense experience were recruited. A panel of martial arts experts selected 21 different techniques including defensive stances, arm blocks, elbow strikes, palm strikes, thumbs to eyes, instep kicks and a carotid neck restraint. The critical elements of each technique were identified by the panel and incorporated into a teaching protocol, and then into a scoring system. Two black belt martial arts instructors directed a total of forty-five 45-minute training sessions. Videotaped proficiency testing was performed weekly. The videotapes were reviewed by the investigators to determine the proficiency levels of each subject for each technique. The techniques were rated by the average number of training sessions needed for an individual to develop proficiency in that technique. The mean number of sessions necessary to train individuals to proficiency ranged from 27 to 38.3. Using this system, the most difficult techniques seemed to be elbow strikes to the rear, striking with thumbs to the eyes and arm blocking. In this study 29 hours of training was necessary to train novice students to be proficient in 21 offensive and defensive martial arts techniques. To our knowledge, this is the first study that attempts to measure the learning curves involved when teaching martial arts techniques.

Medical malpractice is prominently positioned in the consciousness of American physicians, and the perceived threat of malpractice litigation may push physicians to practice defensively and alter their teaching behaviors. The purposes of this study were to characterize the attitudes of academic medical faculty toward malpractice litigation and to identify teaching behaviors associated with fear of malpractice litigation. We surveyed 270 full-time clinically active physicians in the Department of Medicine at a large academic medical center. The survey assessed physicians' attitudes toward malpractice issues, fear of malpractice litigation, and self-reported teaching behaviors associated with concerns about litigation. Two hundred and fifteen physicians responded (80%). Faculty scored an average of 25.5 +/- 6.9 (range = 6-42, higher scores indicate greater fear) on a reliable malpractice fear scale. Younger age (Spearman's rho = 0.19, p = .02) and greater time spent in clinical activities (rho = 0.26, p Fear Scale. Faculty reported that because of the perceived prevalence of lawsuits and claims made against physicians, they spend more time writing clinical notes for patients seen by learners (74%), give learners less autonomy in patient care (44%), and limit opportunities for learners to perform clinical procedures (32%) and deliver bad news to patients (33%). Faculty with higher levels of fear on the Malpractice Fear Scale were more likely to report changing their teaching behaviors because of this perceived threat (rho = 0.38, p < .001). Physicians report changes in teaching behaviors because of concerns about malpractice litigation. Although concerns about malpractice may promote increased supervision and positive role modeling, they may also limit important educational opportunities for learners. These results may serve to heighten awareness to the fact that teaching behaviors and decisions may be influenced by the malpractice climate.

A multisensory, multicognitive approach to teaching pronunciation

Directory of Open Access Journals (Sweden)

Edward Y. Odisho

2007-01-01

Full Text Available The Multisensory, Multicognitive Approach (MMA introduced in this paper is premised on the belief that the seat of language is in the brain prior to its physical manifestation in the form of speech being in the mouth. Hence, in teaching pronunciation, the identity of speech as a cognitive entity prior to being a physical one should be seriously considered in relevant language learning and teaching situations – more so in L2 situations than in L1. The traditional assumption that the ideal and the exclusive sensory modality of teaching pronunciation is the auditory modality is no longer acceptable because a holistic view of speech – in production, transmission and perception – manifests itself not only via the auditory sensory modality, but also equally significantly via the visual and tactile-kinesthetic sensory modalities. It is due to this fact that MMA is described as multisensory, a fact that determines the diversified auditory, visual and tactile-kinesthetic implementational techniques needed for effective and efficient teaching of pronunciation especially to adults. Equally importantly, the multicognitive nature of MMA requires the manipulation of diversified cognitive processes in the form of thinking, associating, analyzing, synthesizing, comparing, contrasting etc… for implementation. According to MMA, the teaching of pronunciation becomes more of a multifaceted educational process than a mere repeat-after-me mechanical parroting of speech sounds. Such an approach requires more effort on the part of the instructor and learner and a stronger collaboration between them through the diversification of teaching and learning styles, respectively. Certainly, MMA requires more time to implement in classroom situations, but the time spent is worth it. MMA is no longer a single technique or drill that tackles one sound at a time; instead, it is a joint selection of cognitive and sensory techniques that are applied concurrently to

This research aims to investigate the enhancement of students' mathematical problem solving through teaching with metacognitive scaffolding approach. This research used a quasi-experimental design with pretest-posttest control. The subjects were pre-service elementary school teachers in a state university in Bandung. In this study, there were two groups: experimental and control groups. The experimental group consists of 60 studentswho acquire teaching mathematicsunder metacognitive scaffolding approach, while the control group consists of 58 studentswho acquire teaching mathematicsunder direct approach. Students were classified into three categories based on the mathematical prior ability, namely high, middle, and low. Data collection instruments consist of mathematical problem solving test instruments. By usingmean difference test, two conclusions of the research:(1) there is a significant difference in the enhancement of mathematical problem solving between the students who attended the course under metacognitive scaffolding approach and students who attended the course under direct approach, and(2) thereis no significant interaction effect of teaching approaches and ability level based on the mathematical prior ability toward enhancement of students' mathematical problem solving.
