基于思维模型建构的“物质检验”初中复习教学研究

Review of “Substance Inspection” Based on Thinking Model in Junior High School

以让学生自主建构物质检验的思维模型为目标设计教学,通过完成物质检验的探究任务,学生自主建构思维模型,形成完整的思路,从而提高解决此类问题的能力。并在北京某中学初三年级进行教学实践,对教学实施效果进行了检验,根据教学实践总结出建构"物质检验"思维模型教学的有效教学策略:基于建模历程与生活情境选择素材;以学生为中心自主建构"物质检验"思维模型,引导学生经历多样化的思维发展过程;学生经历不同层级进阶的模型建构历程。

This paper designed teaching with the aim to help students to construct＂substance inspection＂thinking model autonomously.Through finishing the inquiry tasks of＂substance inspection＂,students could construct thinking model autonomously and form complete ideas,and could improve the ability to solve such problems.This paper carried on the teaching practice in the third grade in a junior high school in Beijing,and tested the effects of teaching practice.According to the teaching practice,this paper summed up the effective teaching strategies of constructing＂material testing＂thinking model：selecting materials based on modeling process and life situation;constructing the thinking model of ＂substance inspection＂independently with students as the center,and guiding students to experience a various of thinking development process;students experienced model construction at different levels.
