运用物理模型构建生物课堂的教学是一种基于经验为基础的教学和学习方式。教师可通过现有的模型,或是自己制作的实物图片,或是学生自主构建的模型,来为课堂增加可视性强的学习资源,以方便学生的观摩和学习,提高课堂效率。实践证明,合理进行物理模型的构建和运用,极易在学生头脑中建立起立体的生物模型,不但为理解知识点奠定了结构性基础,而且随着学习的深入,学生可以借助物理模型的直观性、可视性,进行知识点的回 The use of physical models to build biology classroom teaching is based on experience-based teaching and learning. Teachers can increase the visibility of learning resources in the classroom through existing models, pictures produced by themselves or models independently developed by the students so as to facilitate students' observation and study and improve classroom efficiency. Practice has proved that a reasonable physical model of the construction and use of students in the brain can easily create a three-dimensional biological model, not only to understand the knowledge base has laid the structural foundation, and with the deepening of learning, students can use the intuitive physical model Sexuality, visibility, knowledge point back
