MOOC环境下高校公共体育课程远程教学效果评价方法研究

A Study of Evaluation Methods of Distance Teaching and Learning Effect of College Public PE Curriculum in MOOC Environment

针对高校公共体育课程远程教学效果评价中存在的评价指标权重计算误差大、效果评价精度不高等问题,本文设计了一种新的MOOC环境下高校公共体育课程远程教学效果评价方法。具体为:首先,将效果评价指标划分为远程在线课程层面、可用性层面以及远程学习管理层面等三个层面,通过克朗巴赫系数计算不同指标层面中指标的可信度,完成远程教学效果评价指标选择。然后,采用因子分析方法确定远程教师技能因子、远程课程内容因子以及远程学习者学习行为因子,并对指标进行一致性校验,实现了远程教学效果评价指标构建。最后,借助熵值法计算评价指标的综合权重,通过动态聚类算法设计不同处理层,构建现代远程教学效果评价函数,实现MOOC环境下高校公共体育课程远程教学效果评价。实验结果表明:采用上述方法有效提升了远程教学效果评价的精度。

This paper designs a new evaluation method of distance teaching and learning effect of public physical education(PE)curriculum in colleges and universities in a MOOC environment in view of the existing problems of large calculation error of evaluation indicator weights and inadequate accuracy of effect evaluation.Firstly,effect evaluation indicators are divided to three layers,viz.distance online course layer,applicability layer,and distance learning management layer.Distance teaching and learning effect evaluation indicators were selected according to the reliability of the indicators at different indicator layers,calculated by Cronbach coefficient.Then,the factor analysis method was used to determine the distance teacher’s skill factor,the distance course content factor and the distance learner’s learning behavior factor.A consistency check of the indicators was carried out,and distance teaching and learning effect evaluation indicators were set up.Finally,the comprehensive weight of the evaluation indicator was calculated by entropy method.Different processing layers were designed by dynamic clustering algorithm,and the evaluation functions of modern distance teaching and learning effect were built.The evaluation of distance teaching and learning effect of public PE curriculum in colleges and universities in the MOOC environment was thus completed.The experimental results showed that the proposed method has effectively increased the accuracy of distance teaching effect evaluation.
