在线开放课程《复变函数与积分变换》混合式教学学习评价的量化研究

A Quantitative Study of Performance Assessment on Blending Teaching of Function of Complex Variable and Integral Transform-An Online Open Course

在线教学的交互行为对课程质量有重要影响,但是对学习效果的影响缺乏实证量化研究。本研究以工程数学《复变函数与积分变换》在线开放课程建设、教学活动和学习实践为研究对象,依据教学活动一周期后所统计的数据,利用统计学方法从教学实践开展、学习者学习体验、学习效果评价等方面进行量化研究,分析在线课程教学对学习者学习效果的影响。研究结果表明,参加混合式学习的学习者比传统课堂学习的学习者在成绩上有显著提高;参加混合式学习的学习者成绩与参与在线学习活动的程度具有显著的相关性。在线课程教学和混合式学习对提高学习者学习效果和成绩具有显著的作用。

Due to the shortage of empirical quantitative evidence for the effects of online interactive teaching upon learning results despite its significance for the quality of a course,a quantitative study was made of Function of Complex Variable and Integral Transform,an online open course for Engineering Mathematics,on the basis of an analysis of the data obtained from a cycle of teaching on teaching practice,learners'experience and learning result assessment to reveal the possible effects of online teaching upon learners'performance.The result indicates that participators in the blend learning show significant higher performance compared with those of conventional teaching and their performance is significantly correlated with their participation in online learning.In other words,online teaching and blended learning are able to improver learners'learning result and performance significantly.
