基于规则空间模型的高中生电化学概念理解的认知诊断

Cognitive Diagnosis on Electrochemical Conceptual Understanding of Senior High School Students

以规则空间模型为指导，以电化学基础内容为载体，从知识内容属性和过程属性2个维度构建电化学基础认知属性模型，开展化学学科的认知诊断研究。研究发现电化学基础认知属性模型合理；规则空间模型在电化学基础概念理解中得到了成功的应用；81％的被试群体可归入18种理想反应模型，可有效指导个体和班级开展补救性教学。

Under the guidance of the Rule Space Model, this paper tried to build an electro- chemical cognitive diagnosis model and carry out the research on cognitive diagnosis of chemistry from two dimensions of knowledge content attributes and process attributes. The paper found that the electrochemical cognitive diagnosis model was reasonable; the Rule Space Model had been successfully applied in the basic concept understanding of electrochemistry; 81% subjects groups could be classified as 18 kinds of ideal reaction model, which could effectively guide the in- dividual and class to carry out remedial teaching.
