视频标注辅助的太极拳在线学习研究

A Research on Learning Tai-Chi Online With Video-aided Annotations

为解决传统的太极拳在线学习实施追加反馈时学生认知负担增加的问题,提出视频标注辅助的太极拳在线学习方法。借助所见即所得的矢量图、文本等格式的视频标注生成追加反馈,实施高效的太极拳在线学习定性绩效反馈,降低太极拳在线学习的认知负担,提高在线学习绩效。某高校普通大学生参与了验证实验。课程考核结果表明,视频标注辅助的太极拳在线学习可以显著提高太极拳在线学习的学习绩效。满意度问卷调查显示,视频标注辅助的太极拳在线学习显著提高了学生的太极拳动作技巧在线学习的自我能效,增加了有效在线学习的投入。研究结果为降低体育运动技能在线学习的信息传递损耗和增益学生行为控制提供了实施框架。

To solve the problem of cognitive load placed by follow-up feedbacks in traditional Tai-Chi e-learning,video-aided annotation is adopted to provide Tai-Chi e-learning with scaffolding.With the help of video-aided annotations in vector graphics,text and other formats,WYSIWYG follow-up feedback is formed,and efficient knowledge performance of Tai-Chi e-learning is implemented,and then the cognitive load is released and Tai-Chi e-learning performance is improved.63 students participated in the validation experiment.The course assessment results showed that learning Tai-Chi online with video-aided annotations got an increase of 11.0%and 11.7%respectively in the action skills learning performance and expressive learning performance compared to the traditional Tai-Chi e-learning.And the Tai-Chi e-learning performance has got significant improvement.The satisfaction questionnaire indicated that learning Tai-Chi online significantly improved the students′self-efficacy of movement skills and increased the effective Tai-Chi e-learning investment.The research provides an implementation framework for reducing the loss of information transfer and increasing learning behavioral control in e-learning of sports skills.
