演示实验是初中物理教学最基本的形式。欲使实验卓有成效.必须重视指导学生对实验过程在认知上自觉“内化”。引导学生自觉“内化”就是在演示之后.要求学生描述实验过程.画出示意图形.并让其相互订正补充.直到对过程的描述完全正确为止。以阿基米德定律实验自觉“内化”过程为例.起初两个同学的描述.仅仅停留在表面现象上.画出的示意图也不尽完整.
Demonstration experiment is the most basic form of junior high school physics teaching. In order for the experiment to be effective, it is necessary to pay attention to instructing students to be consciously “internalized” in the cognitive process. Guiding students to consciously “internalize” is after the demonstration. Students are required to describe the experimental process. Draw the schematic shapes and make them complementary to each other until the description of the process is completely correct. Take the Archimedes’s conscious experiment of “internalization” as an example. At the beginning, the description of the two classmates only stayed on the surface phenomenon. The sketches drawn were not complete.
