细节决定成败,初中物理实验很多细节性问题可能直接影响教学效果,因此教师在实验教学中既要能从宏观角度把握实验与教学目标的一致性,更要处理好微观操作层面的问题,以提升教学效果.对此,笔者认为教学中需要重点关注下面四点.一、实验器材的选择精细化进行实验,这也体现在选择实验器材方面.上课之前,教师精心对实验器材进行选择,并反复检查实验效果,进而选出最为适合的实验器材在课堂上进行操作.比如,证实惯性存在的典型实验“打鸡蛋”的器材选择,就 Details determine the success or failure of junior high school physics experiments many details of the problem may have a direct impact on teaching effectiveness, so teachers in the experimental teaching both from a macro perspective to grasp the consistency of the experiment and teaching objectives, but also to deal with micro-level operational issues to enhance Teaching effect.In this regard, I believe that the teaching needs to focus on the following four points.First, the selection of experimental equipment to refine the experiment, which is also reflected in the choice of experimental equipment.Pre-class, the teacher carefully selected experimental equipment, and repeatedly Check the experimental results, and then select the most suitable experimental equipment in the classroom to operate.For example, confirm the inertia of the typical experiment “egg” equipment selection
