基于模型建构的初中生物学概念教学

Teaching of biological concepts in junior high school based on model construction

在“神经调节的基本方式”的教学中,引导学生运用数学模型,使“反射”的概念简单化、外显化。通过自制物理模型及探究实验,使“反射弧”这一抽象的概念直观化、形象化;引导学生构建和修正概念模型,使知识系统化、结构化;通过应用模型,使概念整合化、可视化。

concept of“reflex arc”is made intuitive and vivid with self-made physical models and exploratory experiments.Students are guided to develop and revise conceptual models to systematize and structure knowledge as well as integrate and visualize concepts through the application of models.
