Effects of animation's speed of presentation on perceptual processing and learning     

Katja Meyer  Thorsten Rasch  Wolfgang Schnotz 《Learning and Instruction》2010,20(2):136-145

Animations presented at different speed are assumed to differentially interact with learners’ perception and cognition due to the constraints imposed by learners’ limited sensitivity to incoming dynamic information. To investigate the effects of high and low presentation speed of animation, two studies were conducted. In Study 1, participants were 55 students who learned about the functioning of a four-stroke engine from an animation with user-controlled presentation speed. In Study 2, eye movements of 19 students were analysed for different system-controlled presentation speeds of animation. Results indicated that high presentation speeds accentuated global events (i.e., macro-events), whereas low speeds accentuated local events (i.e., micro-events). However, eye movements were primarily affected by the content rather than the presentation speed of animation.  相似文献

A Criterion-Referenced Approach to Student Ratings of Instruction     

J. Patrick Meyer  Justin B. Doromal  Xiaoxin Wei  Shi Zhu 《Research in higher education》2017,58(5):545-567

We developed a criterion-referenced student rating of instruction (SRI) to facilitate formative assessment of teaching. It involves four dimensions of teaching quality that are grounded in current instructional design principles: Organization and structure, Assessment and feedback, Personal interactions, and Academic rigor. Using item response theory and Wright mapping methods, we describe teaching characteristics at various points along the latent continuum for each scale. These maps enable criterion-referenced score interpretation by making an explicit connection between test performance and the theoretical framework. We explain the way our Wright maps can be used to enhance an instructor’s ability to interpret scores and identify ways to refine teaching. Although our work is aimed at improving score interpretation, a criterion-referenced test is not immune to factors that may bias test scores. The literature on SRIs is filled with research on factors unrelated to teaching that may bias scores. Therefore, we also used multilevel models to evaluate the extent to which student and course characteristic may affect scores and compromise score interpretation. Results indicated that student anger and the interaction between student gender and instructor gender are significant effects that account for a small amount of variance in SRI scores. All things considered, our criterion-referenced approach to SRIs is a viable way to describe teaching quality and help instructors refine pedagogy and facilitate course development.  相似文献

Nutrition for winter sports     

Meyer NL  Manore MM  Helle C 《Journal of sports sciences》2011,29(Z1):S127-S136

Winter sports are played in cold conditions on ice or snow and often at moderate to high altitude. The most important nutritional challenges for winter sport athletes exposed to environmental extremes include increased energy expenditure, accelerated muscle and liver glycogen utilization, exacerbated fluid loss, and increased iron turnover. Winter sports, however, vary greatly regarding their nutritional requirements due to variable physiological and physique characteristics, energy and substrate demands, and environmental training and competition conditions. What most winter sport athletes have in common is a relatively lean physique and high-intensity training periods, thus they require greater energy and nutrient intakes, along with adequate food and fluid before, during, and after training. Event fuelling is most challenging for cross-country skiers competing in long events, ski jumpers aiming to reduce their body weight, and those winter sport athletes incurring repeated qualification rounds and heats. These athletes need to ensure carbohydrate availability throughout competition. Finally, winter sport athletes may benefit from dietary and sport supplements; however, attention should be paid to safety and efficacy if supplementation is considered.  相似文献   

德语国家普通教学论的核心命题与时代课题     

希尔伯特·迈尔  任平  卡罗拉·尤汉娜斯 《教育研究》2022,43(1):100-114

德语国家(德国、奥地利以及瑞士)普通教学论历史悠久,对整个教育学科的建立与发展意义重大。普通教学论作为系统性、普遍性的教学理论,强调自身理论的主体性、师生对话的意义建构、教师清晰的指导与管理、教学的反思性实践。新的时代背景下,德语国家普通教学论的发展既坚守传统,又积极转向,系统分析其优劣特质可以发现:相关理论一方面具有整体性、独特性、指导性、反思性、规范性等特征;另一方面也面临着诸如学科地位下滑、缺乏实证研究支撑、自身理论发展缓慢、缺乏课程研究支持等问题。为应对信息技术时代学校教育的异质性、融合教育、移民教育、健康教育、数字化教育等新兴教学情境,相关研究呈现出新的发展趋势,转向"技术支持下团队合作"、"多主体协同建构"、"制定数字化教学新标准"。  相似文献   

Retention of EBM competencies     

Dorsch J  Aiyer MK  Gumidyala K  Meyer LE 《Medical reference services quarterly》2006,25(3):45-57

This longitudinal follow-up study surveyed the attitudes toward, and skills in, evidence-based medicine (EBM) of medical school graduates who had participated in a formal EBM curriculum during their third-year Internal Medicine (IM) clerkship. The objective was to measure whether competencies were retained over time and to identify the long- term impact on the graduates' attitudes toward, and proficiency in, EBM after graduation. Questionnaire results showed that a group of medical school graduates retained EBM skills and a positive attitude about the importance of applying EBM principles in patient care one to three years after completing an EBM course.  相似文献

Teaching the partial products algorithm with the concrete representational abstract sequence and the strategic instruction model     

Margaret M. Flores  Alexcia J. Moore  Jill M. Meyer 《Psychology in the schools》2020,57(6):946-958

Elementary standards include multiplication of single-digit numbers and students advance to solve complex problems and demonstrate procedural fluency in algorithms. The ability to illustrate procedural fluency in algorithms is dependent on the development of understanding and reasoning in multiplication. Development of multiplicative reasoning provides the foundation for advanced mathematics and algebraic reasoning. For students who struggle in mathematics, instruction in multiplication algorithms should ensure conceptual understanding so that students have a foundation for success in advanced mathematics. The concrete representational abstract (CRA) sequence addresses conceptual understanding and the strategic instruction model (SIM) supports procedural knowledge. The current pilot study combined these methods to teach elementary students the partial products algorithm. Twelve students in grades four and five participated in the study, receiving instruction from teachers in their school during an intervention period. Within a pre-experimental design, using pre- and postintervention data, students showed a significant change in performance. The article will describe and show how teachers implemented the CRA-SIM interventions and discuss implications for practice.  相似文献   

Impressions of disadvantage: II-Monitoring and assisting the student at risk     

J. H. F. Meyer  A. F. Cliff  T. T. Dunne 《Higher Education》1994,27(1):95-117

Two studies on monitoring and assisting students at risk are presented against a contemporary perspective in higher education: that of monitoring and developing the quality of student learning. A basis for risk categorisation at an individual level is outlined, and the effects of an intervention aimed at students at risk are evaluated in two contrasting settings. At risk in the present study represents, in conceptual terms, a relatively extreme set of learning behaviours.The first study approximates an ideal set of circumstances in which an individual-level intervention for students conceptually at risk is described. The second study reflects the uncompromising reality of a large first-year service course, in which a reduced form of the same intervention was pragmatically attempted. In both interventions the emphasis was on assisting students to engage manifestations of their own self-reported, contextualised study behaviour. This was the starting point of a developmental and reflective programme in which students were not taught study skills, but were rather assisted to develop deeper contextual perceptions, metalearning awareness, and internal locus.The targeted students in these studies, and the basic nature of the intervention employed, differ considerably from those used in other intervention studies. The first study produced positive results, while the second study did not. An overall conclusion is that, while interventions of the type described can assist students to develop their learning potential, they can only do so in carefully managed circumstances that are sensitive to individual students' learning problems and the discipline-specific context in which these occur.  相似文献
