当前课程改革的一个方向是倡导“以学生为主体,教师为主导”的探究式教学方式,主张学生积极、主动求知。演示实验是驱动学生积极思维、达成有效教学的一种重要手段,在日常教学中,借助演示实验构建高效课堂是一线教师面对的既现实又迫切的一个课题。基于以学定教的理念,结合平时的教学实践,笔者对初中物理演示实验的有效设计从组织形式角度进行了分类。
At present, one direction of curriculum reform is to advocate inquiry-based teaching mode of “taking students as the mainstay and teachers as the mainstay”, and advocating students to actively and initiatively seek knowledge. Demonstration experiment is an important means to drive students’ positive thinking and reach an effective teaching. In daily teaching, building an effective classroom with demonstration experiments is a realistic and urgent subject faced by front-line teachers. Based on the idea of learning to teach, combined with the usual teaching practice, the author classifies the effective design of junior high school physics demonstration experiment from the perspective of organization.
