物理是一门实验学科,实验当然是极其重要的,但是在课堂教学中如果因此而搞“大套魔术”哗众取宠就走向了反面。实验,特别是演示实验,必须从“突出重点、点拨思维”的需要出发,精心设计使实验显示的物理现象紧紧围绕教学的重点创设物理情境、提供强刺激,充分发挥点拨作用。这就需要我们精心设计实验、精心制作相应的教具。 Physics is an experimental discipline, and experimentation is of course extremely important. However, if you engage in “big sets of magic” in the classroom teaching, then it will be the opposite. Experiments, especially demonstration experiments, must proceed from the requirement of “focusing on and focusing on thinking.” Carefully designed so that the physical phenomena demonstrated by the experiment will focus on the focus of teaching to create physical situations, provide strong stimulation, and give full play to the dialing role. This requires us to meticulously design experiments and elaborate the corresponding teaching aids.
