高中物理教学中“情”“景”“型”解决问题的教学策略探索——“情景、模型、迁移”的建构

Research on teaching strategies of scenario and model in Physics teaching——Building“Scenario, Model and Migration”

在"等效电源"模型的教学中,学生只会利用最简单的模型分析解题,而不能将模型进行知识迁移。在具体的教学和习题讲解中,教师可以通过营造简单的"情"与"景",构建最简单的"雏型",再通过引导分析后发展定"型"。从而使学生建构起"等效电源"的情、景和型,对等效电源模型的运用形成正迁移。

When teachers tried to use ＂Equivalent source＂ mode in teaching, they always found students can only do simple analyses rather than migrate the models. Therefore, teachers should build simple models by using scenarios, and lead students to develop models in order to help them to understand positive migration of ＂Equivalent source＂ model.
