我国高尔夫球奥运选手与世界优秀选手一号木数据对比分析     

赵紫龙 《河北体育学院学报》2020,34(6):85-90

采用文献资料法、实地考察法、数理统计法和对比分析法，对我国奥运选手和世界优秀选手的一号木数据进行分析。发现，在实地考察的球洞中，世界优秀选手全四轮均使用一号木开球，而我国男子选手则是一号木、三号木交替开球，可能是由于对自身一号木开球技术不够自信；我国男子选手的一号木平均开球距离、上球道率较世界优秀选手均差距较大；我国女子选手的一号木平均开球距离与世界优秀选手较为接近，但上球道率有待提高。建议，男子选手加强开球距离和上球道率的训练，女子选手加强上球道率的训练；冯珊珊进一步提升开球距离；在比赛前要对场地进行多次熟悉，找到合适的开球策略。  相似文献

Strength,Weakness, Opportunity,Threat (SWOT) Analysis of the Adaptations to Anatomical Education in the United Kingdom and Republic of Ireland in Response to the Covid-19 Pandemic

The Covid-19 pandemic has driven the fastest changes to higher education across the globe, necessitated by social distancing measures preventing face-to-face teaching. This has led to an almost immediate switch to distance learning by higher education institutions. Anatomy faces some unique challenges. Intrinsically, anatomy is a three-dimensional subject that requires a sound understanding of the relationships between structures, often achieved by the study of human cadaveric material, models, and virtual resources. This study sought to identify the approaches taken in the United Kingdom and Republic of Ireland to deliver anatomical education through online means. Data were collected from 14 different universities in the United Kingdom and Republic of Ireland and compared adopting a thematic analysis approach. Once themes were generated, they were collectively brought together using a strength, weakness, opportunity, threat (SWOT) analysis. Key themes included the opportunity to develop new online resources and the chance to engage in new academic collaborations. Academics frequently mentioned the challenge that time constrains could place on the quality and effectiveness of these resources; especially as in many cases the aim of these resources was to compensate for a lack of exposure to cadaveric exposure. Comparisons of the actions taken by multiple higher education institutions reveal the ways that academics have tried to balance this demand. Discussions will facilitate decisions being made by higher education institutions regarding adapting the curriculum and assessment methods in anatomy.  相似文献   

Social influence on endorsement in social Q&A community: Moderating effects of temporal and spatial factors     

《International Journal of Information Management》2021

This study examines the impacts of social influence, which are manifested by popularity and source credibility, on social endorsement in social Q&A community; and how the relationship is impacted by temporal-spatial factors. By collecting panel data from a large platform, the results of an econometric model demonstrate that popularity and source credibility are positively associated with social endorsement. With respect to the moderation effects, the results further show that time distance strengthens the effect of popularity on the social endorsement, but undermines the effect of source credibility; while crowdedness plays the role that strengthens the impact of popularity on the social endorsement, it has no significant moderating effect on the relationship between source credibility and social endorsement. Both theoretical and practical implications are discussed.  相似文献   

Effects of pairs of problems and examples on task performance and different types of cognitive load     

《Learning and Instruction》2014

In two studies, we investigated whether a recently developed psychometric instrument can differentiate intrinsic, extraneous, and germane cognitive load. Study I revealed a similar three-factor solution for language learning (n = 108) and a statistics lecture (n = 174), and statistics exam scores correlated negatively with the factors assumed to represent intrinsic and extraneous cognitive load during the lecture. In Study II, university freshmen who studied applications of Bayes' theorem in example–example (n = 18) or example–problem (n = 18) condition demonstrated better posttest performance than their peers who studied the applications in problem–example (n = 18) or problem–problem (n = 20) condition, and a slightly modified version of the aforementioned psychometric instrument could help researchers to differentiate intrinsic and extraneous cognitive load. The findings provide support for a recent reconceptualization of germane cognitive load as referring to the actual working memory resources devoted to dealing with intrinsic cognitive load.  相似文献   

Is there a role for direct instruction in problem-based learning? Comparing student-constructed versus integrated model answers     

《Learning and Instruction》2014

Problem-based learning (PBL) requires students to formulate learning issues that need to be answered by studying multiple literature resources. Advocates of high instructional guidance argue that this is too cognitively demanding for students and ineffective for learning. Therefore, we examined the effects of studying an integrated model answer in the self-study phase in PBL. Participants (N = 62) engaged in a simulated group discussion, ending with the establishment of learning issues. Then they either studied integrated model answers to the learning issues, or undertook a standard PBL self-study phase in which students needed to construct their own answers based on multiple literature resources. Higher learning outcomes were obtained for the participants who studied integrated model answers when compared to the participants who constructed their own answers. These higher learning outcomes were obtained with lower investment of self-study and equal investment of mental effort during learning.  相似文献   

基于远程条件培养农民大学生的实践探索——以湖南广播电视大学为例     

彭瑛 《邵阳学院学报(社会科学版)》2011,10(3):118-121

实践表明,基于远程条件培养农民大学生必须加强内外联合,实现资源的优势互补与共享;强化基本条件,满足农民大学生培养的教学需求;坚持系统办学,形成教学与管理合力;打造教学团队,远近结合创新教学。随着"一村一名大学生计划"持续深入而全面的开展,基于远程条件的农民大学生培养项目在稳步推进中,也凸现出诸如农民大学生培养项目发展后劲不足、培养经费有限、专业设置相对滞后等问题。为解决这些问题,需要争取政策,加强合作,持续推进;城乡统筹,适时转型,协调发展;开放理念,创新模式,打造品牌。  相似文献   

远程学习服务质量影响路径的实证研究     

黄复生 《远程教育杂志》2011,29(6):44-50

学习者是远程教育的中心。市场营销中的相关理论能对研究远程学习服务质量具有借鉴作用。3789份的大样本调查数据的结构方程模型的路径分析,首次在远程教育领域验证了"服务质量→服务价值→服务满意感→行为意向"的主要影响路径。远程学习者选择远程学习服务的心理机制和行为路径是:远程学习服务质量是通过服务价值、服务满意感来对学习者行为意向产生作用。这一发现为更好地服务远程学习者提供了理论基础,也为远程学习者自身教育服务消费能力建设提供借鉴作用。  相似文献

控制论视野中的远程教育管理服务支持系统     

张亚斌 《现代远程教育研究》2003,(3):38-43

远程教育管理服务支持系统的运行状态直接关系到远程教育事业的发展,借助控制论的有关观点考察分析其一般运行原理,我们发现,面对这样一种为远程教育事业提供经营、控制、协调等强大支援的“社会化职能结构系统“、远离平衡的“开放系统“、不断耗散物质能量才能维持有序状态的“稳定系统“、通过非平衡突变而不断走向新的有序稳定状态的“自组织系统“,管理者只有学会运用“协同理论“,将其“内耗量“降到最低点,才能将更多的能量耗散在管理服务支持的“自组织“过程当中.  相似文献
