教案作为教师教学工作的组成部分，在现代教师的专业发展中起着重要的作用。首先，现代教学是一个复杂的过程，教案能帮助教师最大程度地把握教学的确定性；其次，教案不同于课堂临场发挥行为，它更便于教师进行教学反思。但是，通过文献调研，笔者发现现有教案评估方面的研究并没有切中教案的本质，也没有给出高质量的教案应该具备的客观特征及其数据依据。教案的实质是设计态的教学系统，本文从系统论出发，对比现有教学系统分析方法的优缺点，说明对教案进行IIS图分析的必要性；通过前期关于教学系统IIS图分析法的一系列实证研究，说明对教案进行IIS图分析的可行性与有效性，从而提出基于教学系统IIS图分析法分析教案、构建教案质量评估指标体系的新思路。1)制定详尽、准确的教案IIS图切分的操作规范本研究首要解决的问题是如何基于教学系统IIS图分析法分析教案，即制定教案IIS图分析的操作规范，这是一个从具体到抽象的过程，笔者经过长时间、反复的研究，不仅从激活量属性上，更从表征形态、信息类型上进行了更详尽、更准确的界定，这是本研究的一个重要成果。2)构建教案评估的特征指标这更是一个反复迭代的过程。首先，在前期研究的基础上，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。3)验证本研究的有效性有效性的验证包含两个方面：一个是教案IIS图切分操作规范的一致性研究；一个是教案特征指标量化方式的有效性研究。通过一系列的实证分析，我们确定教案IIS图切分规范是有效的，且教案评估的9个指标在统计意义上是显著的。4)构建教案质量评估的指标体系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①整图知识点总激活量、②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)、③学生参与度(目标知识点激活量)、④媒体多元性(目标知识点表征形态数均值)、⑤信息流类型完整性(信息类型数)、⑥目标手段一致性。

As a part of the teaching work, teaching plan plays an important role in the modern teachers' professional development. Firstly, modern teaching is a complex process and teaching plan can help teachers maximize the certainty of teaching; Secondly, unlike real-time teaching, it is more convenient for teachers to reflect on teaching with the help of teaching plan. However, through literature research, I found the existing studies are untenable. They didn’t seize the essence of teaching plan and didn’t get the objective characteristics and data basis of teaching plan. In essence, teaching plan is the designed instructional system. By comparing advantages and disadvantages of the existing instructional system analysis, the paper points out the necessity of analyzing the teaching plan based on IIS Map. And, by integrating the previous empirical research on IIS Map, the paper points out the feasibility and validity of analyzing the teaching plan based on IIS Map. Then, the paper puts forward a new idea of building teaching plan’s characteristic indicator system based on IIS map.1)Develop detailed and accurate operating specifications of analyzing teaching plan based on IIS mapIn this study, the primary problem is how to analyze teaching plan based on IIS map, which is a process from concrete to abstract. Considering the features of IIS Map and teaching plan, I develop detailed and accurate operating specifications of analyzing teaching plan based on IIS map, especially about the definition of information representation type and information flow type. This is an important outcome of the study. 2)Construct teaching plan’s characteristic indicators This is an iterative process. Firstly, based on the previous studies, considering the elements and functional characteristics of the teaching system, I propose five teaching plan’s characteristic indicators conceptually; secondly, based on the structured design of teaching plan and the tag information of IIS map, I construct teaching plan’s characteristic indicators quantitatively. 3)Verify the study’s validityValidity of the study contains two aspects: the consistency of teaching plan’s analysis based on IIS map and the validity of teaching plan’s characteristic indicators. By empirical research, we verify the effectiveness of teaching plan’s analysis based on IIS map and get 9 significant indicators. 4)Build teaching plan’s characteristic indicator systemBy principal component analysis for the 9 significant indicators, considering the specific meaning of the characteristic indicators and following the simple principle, we build a both simple and effective teaching plan’s characteristic indicator system, that is,①the Total Quantity of Activation(all points),②Target Points’ Degree of Activation,③the Degree of Student Engagement(target points’ Quantity of Activation),④the Diversity of the Media (the average of target points’ representation types),⑤the Integrity of the Information Flow Type (the number of information flow types),⑥Target-Means Consistency.
