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

Popularization and Teaching of the Relationship Between Visual Arts and Natural Sciences: Historical, Philosophical and Didactical Dimensions of the Problem     

Xenia Arapaki  Dimitris Koliopoulos 《Science & Education》2011,20(7-8):797-803

The need for a convergence of the visual arts and the natural sciences within the framework of both formal (schools, universities) and non -formal education (museum) at the level of dissemination and popularization of this knowledge is something that has preoccupied the communities of artists, scientists and educators. In the present work we aim to present in a concise way certain positions with regard to the historical, philosophical and didactical dimensions of the problem of popularizing and teaching the relation between the visual arts and the natural sciences. More precisely, we intent to show the existence of this relation throughout history and within the society by reference to certain typical examples of how scientific ideas about nature and the propagation of light influenced the practices of the neo-impressionists or the early abstract painters in relation to the use of colour or the way the visual arts aid in the representation of scientific objects and/or ideas. At the epistemological level, we are going to put forth Levy-Leblond??s idea that the relation between the visual arts and the natural sciences is a relation of meeting, controversy or even conflict but definitely not a relation of confusion or fusion. Furthermore, at the didactical level we aim to present the popularization and the teaching of the relation between the visual arts and the natural sciences as a problem of the didactic transformation of knowledge and reference practices and not as a clearly pedagogical construct.  相似文献   

Field dependence/independence cognitive style and problem posing: an investigation with sixth grade students     

Aristoklis Andreas Nicolaou  Xenia Xistouri 《教育心理学》2011,31(5):611-627

Field dependence/independence cognitive style was found to relate to general academic achievement and specific areas of mathematics; in the majority of studies, field-independent students were found to be superior to field-dependent students. The present study investigated the relationship between field dependence/independence cognitive style and problem-posing ability among sixth grade students. The 94 students’ sample was clustered into three groups, according to the cognitive-style field dependence/independence (field dependents, field mixed and field independents). The results suggest that field-independent participants outperformed field-mixed and field-dependent ones in both problem-posing ability and the complexity of the problems posed. It was also found that the content of the task influenced the differences between the three groups of students as regards the ability in problem posing and the complexity of the problems posed; while in the first (informal context), second and fourth task differences were found between the groups, in the third task (formal context), no differences were evident. The results are interpreted in consideration to the relevant literature findings. Some educational implications are discussed and directions for future research are drawn.  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
