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   

高校大学生MOOC持续使用行为研究——基于ECM-ISC和承诺信任理论          下载免费PDF全文

乐承毅路亭李佩佩 《宁波大学学报(教育科学版)》2022,(1):92-099

新型冠状病毒疫情为MOOC平台带来的机遇,但也面临如何继续留住用户的挑战。厘清高校大学生用户MOOC持续使用行为的影响因素,对MOOC平台优化服务、提升用户体验具有重要意义。本文基于ECM-ISC模型,结合考虑交互关系的承诺信任理论模型,对高校大学生MOOC持续学习行为的因素及各因素之间的关系进行了实证分析。研究结果表明:内在动机是学习者满意度的主要影响因素;信任是用户持续使用MOOC平台的重要影响因素;引入信任和承诺后的用户持续使用行为模型具有更强的解释力;信任与承诺在满意度对用户持续使用的正向影响中起到部分中介和链式中介作用。  相似文献   

基于校企合作的高职学生职业发展研究     

张定华  乐虞莹 《宁波职业技术学院学报》2014,(2):28-30

高职学生职业发展存在的问题主要有：高职院校对学生职业发展认识不足;企业对人才培养的前瞻性不够;学校与企业合作培养制度不完善。校企合作是培养现代化新型人才的必经之路,是职业教育与市场对接的迫切要求,是增强学生职业能力的重要举措,因此,校企合作是解决当前高职学生职业发展问题的关键。以促进高职学生职业发展为目标的校企合作,首先要改变观念,重视校企合作;其次要定位双赢,实现优势互补;第三是完善制度,提升人文关怀。  相似文献
