物理教学必须以实验为基础。初二的物理教学 ,更应该重视实验的作用。教学中 ,教师应尽量提供实验机会让学生在观察与实验的过程中积累物理表象 ,形成感性认识 ,并通过多种感觉器官的体验 ,加深对物理知识的理解 ,优化思维的品质。下面笔者就初二物理第八章的“重力”和“互成 Physics teaching must be based on experiments. The second physics teaching should pay more attention to the role of experimentation. In teaching, teachers should try to provide experimental opportunities to allow students to accumulate physical representations in the process of observation and experimentation to form perceptual knowledge, and to deepen understanding of physical knowledge and optimize the quality of thinking through the experience of various sensory organs.
