教学分析方法的对比研究

Comparison of Instruction Analytical Methods

定量的教学分析是指把教学过程切分为更细的片段，并对片段进行编码，进而从片段的编码数据出发推断教学某 种整体特征的过程。这种教学分析目前有行为系统和信息系统两种视角的分析方法。文章从编码对象和编码体系、操作逻辑、 预期结论、研究的科学性水平和实践指导意义等四个方面对S-T、FIAS、CSCL、IIS 图等典型的教学分析方法做了对比研究， 发现行为系统视角下的分析方法在编码体系和科学性水平方面具有明显缺陷，而IIS 图方法具有更好的客观性和实用性，是教 学分析实践的更合理地选择。

Quantitative instruction analysis refers to the process of dividing the teaching process into finer fragments， encoding the fragments， and inferring some kind of overall characteristics depending on the fragments’ encoded data. Quantitative instruction analysis can be divided into two perspectives: the behavioral systems analysis and the information systems analysis. In this paper， detailed comparison among typical instruction analytical methods of S-T， FIAS， CSCL and IIS chart is made in four aspects， including encoding objects and coding system， the operating logic， the desired conclusion， the scientific level and practical guidance significance. The conclusion is that the behavioral systems analysis has obvious disadvantages in coding system and scientific level， yet the method of IIS chart which has better objectivity and practicality is the more reasonable choice to practice teaching analysis.
