摘要
根据代数的一般化,变换和元水平活动三种核心活动,结合教师本质性知识的正确,意义和联系三个认知水平,构建出初中二次函数的领域模型的框架,分别呈现了二次函数的三种核心活动的行为指标,并将对应的评测案例进行分析.
Based on the three core activities of algebra:generalization,transformation and meta-level activities,in combination with the three cognitive levels(correctness,significance and connection)concerning the essential knowledge of the teacher nature,a framework of the quadratic function domain model of junior high school is constructed and its behavior indicators of the three core activities are presented respectively.And the corresponding evaluation cases are analyzed.
