基于IIS图分析的教案质量评估指标体系的构建

A Research on Building Teaching Plan’ Characteristic Indicator System Based on IIS Map

教案的实质是设计态的教学系统，该文尝试采用教学系统IIS图分析法分析教案，在前期研究的基础上，笔者结合教学系统的要素与功能特征，从概念层面提出教案的特征指标；其次，通过对教案的IIS图分析，从教案的结构化设计及IIS图的标记信息入手，构建教案特征指标的具体量化方式，对统计意义上显著的9个子指标进行主成分分析，结合教案特征指标的具体含义，遵循简洁的原则，构建一套既简洁又有效的教案质量评估的指标体系，即整图知识点总激活量、目标知识点激活度(目标知识点平均激活量与IIS整图知识点平均激活量的比值)、学生参与度(目标知识点激活量)、媒体多元性(目标知识点表征形态数均值)、信息流类型完整性(信息类型数)、目标手段一致性。

In essence， teaching plan is the designed instructional system， the paper tries to analyze the teaching plan based on IIS Map. Firstly， based on the previous studies， considering the elements and functional characteristics of the teaching system， the paper proposes teaching plan’s characteristic indicators conceptually; secondly， based on the structured design of teaching plan and the tag information of IIS map， the paper constructs teaching plan’s characteristic indicators quantitatively; then， by principal component analysis for the 9 significant indicators， considering the specific meaning of the characteristic indicators and following the simple principle， the paper builds a both simple and effective teaching plan’s characteristic indicator system， that is， the total quantity of activation(all points)， target points’degree of activation， the degree of student engagement(target points’ quantity of activation)， the diversity of the media (the average of target points’ representation types)， the integrity of the information flow type (the number of information flow types) ， target-means consistency.
