远程教育网上教学反馈信息的分析与应用

Analysis and application for on-line learning feedback information in distance education

本文应用控制论、信息科学、应用数学与教学系统设计等方法,探讨了信息化环境下的远程教育网上教学信息的分析与应用问题。首先,设立了网上教学反馈信息的定量描述函数,应用这些函数可以从多个维度去描述典型的网上学习行为。其次,基于动力系统稳定性理论建立了判断教学目标发生偏差的定量比较方法。第三,应用数据挖掘的方法,构建了学习行为规律的两个模型。第四,提出了一个把反馈信息应用到教学过程的调节与优化之中的应用模型,分析比较了该模型与一般传统的教学设计模型的特征差异。最后,以典型的实际案例说明了如何应用反馈信息来进行补偿教学。

This article has applied such methods as control theory, information science, applied mathematics and teaching system design, etc. to explore analysis and application issues of on-line teaching information of distance education under information context. The article first established quantitative descriptive function for feedback information of online teaching and used these functions to describe on-line learning behaviors from different angles. Based on the stable theory of dynamic system, they have developed quantitative comparison method to judge the differences occurred in teaching objective. Thirdly, by using data digging methods, they constructed two models of learning behavior law. Fourthly, they proposed an applied model to apply feedback information to regulating and optimizing process of teaching and made analysis and comparison of the distinctive features of this mode with a general traditional teaching design model. In the end, the authors explained how to use feedback information to supplement teaching through some practically typical case studies.
