基于建模和论证教学的“减数分裂”教学设计

"Meiosis" Teaching Design Based on Modeling and Demonstration Teaching

本文基于整合建模和论证过程的渗透式教学模式(SNP模式),在组织学生小组合作构建"减数分裂"模型过程中,通过教师分阶段给予科学证据,引导学生在"解释证据—质疑、重建、完善模型—得出结论"的过程中自主构建概念.

This paper is based on combination of model and process of demonstration (SNP Model). During the process of constructing "meiosis" model by group cooperation, and the process of explaining evidence, questioning, reconstructing and perfecting the model, drawing a conclusion, students are guided to shape the concept by teacher who offers scientific evidences in various stages of the process.
