近年来,随着单板滑雪U型场地技巧项目的快速发展及国际运动成绩的快速提升,我国运动员在训练方面遇到了很多问题,如运动员在完成高难度的空中技术动作后,在落地时总是出现失误,直接影响运动员在比赛中的成绩.本文采用文献资料、专家访谈、录像分析等研究方法,对黑龙江省单板滑雪U型场地技巧优秀运动员的落地稳定性进行了分析,具体涉及运动员成套动作落点分析、滑行路线分析和运动员平衡能力,研究结果认为,运动员的平衡能力差和落点区域的不同选择是导致落地稳定性差的主要原因.为帮助单板滑雪U型场地技巧项目备战2018年平昌冬奥会提供了一定的理论依据.  相似文献

Blended learning in higher education: professional development in a Hong Kong university     

Jennifer Catharine Evans  Hennie Yip  Kannass Chan  Christine Armatas  Ada Tse 《高等教育研究与发展》2020,39(4):643-656

ABSTRACT

Online learning has become a ubiquitous part of the educational landscape and how teachers are supported in developing approaches to teaching online is a fundamental aspect of the students’ learning experience. Based on the implementation of a professional development course on becoming an online teacher offered in a blended learning mode at one university in Hong Kong, this article proposes that offering this type of professional development in a blended mode is very effective in facilitating enhanced usage of the university’s learning management system. In a blended mode, teachers are actively engaged with blended learning and were found to make more extensive use of features/tools in Blackboard after they attended the professional development course. Results support that offering professional development in a blended mode provides teachers with an authentic student perspective, at the same time as they take guided steps in the teacher’s role in blended learning.  相似文献   

A new footwear technology to promote non-heelstrike landing and enhance running performance: Fact or fad?

This study sought to compare the kinetics and kinematics data in a group of habitual shod runners when running in traditional running shoes and newly designed minimalist shoes with lug platform. This novel footwear design claims to simulate barefoot running and reduce energy loss during impact. We compared footstrike angle (FSA), vertical average (VALR) and instantaneous (VILR) loading rates, energy loss and initial vertical stiffness between two shoe conditions. Runners demonstrated a decreased FSA while running in minimalist shoes with lug platform than traditional shoes (P = 0.003; Cohen’s d = 0.918). However, we did not observe a landing pattern transition. VALR and VILR between two footwear conditions showed no significant difference (P = 0.191–0.258; Cohen’s d = 0.304–0.460). Initial vertical stiffness (P = 0.032; Cohen’s d = 0.671) and energy loss (P = 0.044; Cohen’s d = 0.578) were greater when running in minimalist shoes with lug platform. The results show that minimalist shoes with lug platform reduce the FSA but may not lead to a landing pattern switch or lower vertical loading rates. Interestingly, the new shoe design leads to a greater energy loss than traditional running shoes, which could be explained by a higher initial vertical stiffness.  相似文献

在大学生体质健康现状的视野下,响应国家“阳光长跑”活动的政策,借鉴成功的实践经验,采用实验法,制定“阳光长跑”干预实施方案,开展研究工作.结果显示:1)大学生在4个月的“阳光长跑”活动干预下,有氧耐力、柔韧素质有显著性的变化,而速度素质、平衡能力变化不明显;2)“阳光长跑”活动干预对提高机体有氧代谢酶活性、呼吸机能、刺激腰背部、腿部肌群柔韧性有重要帮助,而对大学生腿部力量、脚踝力量、机体平衡能力的刺激较小,没有显著影响.  相似文献   

Tracking Pre-service Teachers’ Changing Conceptions of Good Science Teaching: The Role of Progressive Reflection with the Same Video     

Benny Hin Wai Yung  Siu Ling Wong  Man Wai Cheng  Ching Sum Hui  Derek Hodson 《Research in Science Education》2007,37(3):239-259

A CD-ROM consisting of videos of two lessons by different teachers demonstrating exemplary science teaching was used to elicit, develop and track the changing conceptions of good science teaching of student teachers enrolled for the one-year Postgraduate Diploma in Education (PGDE) at several stages during the programme. It was found that the videos acted as an effective probe to elicit student teachers’ conceptions and had significant impact on those conceptions at different stages of the programme through the provision of teacher models demonstrating exemplary teaching. The experience has extended novice teachers’ awareness of alternative teaching methods and approaches not experienced in their own schooling, broadened their awareness of different classroom situations, provided proof of existence of good practices and prompted them to reflect on their current conceptions of good science teaching. Most importantly, the strategy of asking student teachers to watch the same videos on three separate occasions at different times of the course was recognized by them as a crucial element in facilitating their reflection on their changing conceptions of good science teaching. PGDE is the standard form of pre-service teacher education in Hong Kong. It provides qualified teacher status within Hong Kong. Student teachers enrolled for the PGDE have completed a relevant undergraduate degree.  相似文献

Exploring inclusive pedagogical practices in Hong Kong primary EFL classrooms     

Cheri Chan  Margaret Lo 《International Journal of Inclusive Education》2017,21(7):714-729

Social diversity is now commonplace in many communities in today’s globalised world. This diversity can be seen in any classroom of learners, and international studies have shown the complex ways in which disabilities, race, ethnicity, gender and social class can determine a child’s opportunity to succeed or fail in the education system. In Hong Kong, like in many educational contexts around the world, teachers are grappling with increasing diversity amongst their students, including teaching students with special educational needs (SEN) and non-Chinese speaking students (NCS) living in Hong Kong. This paper examines how three primary TEFL (Teaching English as a Foreign Language) teachers are constructing identities as inclusive practitioners as they grapple with enacting the inclusive education policy recently introduced into Hong Kong schools. The data are drawn from a small-scale collaborative reflective inquiry for teacher professional development. Drawing upon a sociocultural and critical framing of identity theory, we trace the three teachers’ identity construction as EFL teachers and inclusive education practitioners. We view the role of discourse, self-positioning and social context as key processes in teacher identity formation. Implications for furthering the development of inclusive education in EFL classrooms are offered.  相似文献   

Experiential learning in doctoral training programmes: fostering personal epistemology through collaboration

There has been increasing recognition for the need to reform doctoral training practices to foster students’ personal epistemology. This study describes the design and evaluation of a learning experience designed to help students understand the scholarly publication process. Firstly, this study discusses the design of the learning experience, describing the collaborative process of writing an interdisciplinary publication using both online and face-to-face learning. Secondly, this study evaluates the effectiveness of the learning experience by examining students’ reflections. We show that participation in the learning experience helped students to develop their academic writing proficiency, collaboration and teamwork, intercultural competence, and ability to engage in reflective practice. Importantly, we show that each student also created more individualised knowledge, gaining insight into how they and others think. This study, therefore, demonstrates that personal epistemology can be fostered through collaboration in a doctoral writing group context.  相似文献
