物理是一门以实验为基础的的学科,实验在物理教学中有十分重要的作用。因此,我认为初中物理教学应十分注重实验教学,切实加强实验教学。一、引导学生观察物理现象,激发学生的学习兴趣,培养他们的观察能力在观察这些物理现象时,教师要引导学生注意整个现象发生的过程、产生的条件和特征等。如在观察“摩擦起电”现象时,要提示注意:1、手帕摩擦过的塑料膜对碎纸屑有什么作用?2、手帕摩擦过的两块塑料膜,在相互接近时,
Physics is an experiment-based discipline, and experiments play a very important role in physics teaching. Therefore, I think that junior high school physics teaching should pay great attention to experiment teaching and practically strengthen experiment teaching. First, to guide students to observe the physical phenomena, to stimulate student interest in learning and develop their observation ability In observing these physical phenomena, teachers should guide students to pay attention to the phenomenon of the whole phenomenon, the conditions and characteristics produced. As in the observation “friction electrification ” phenomenon, to be prompted to note: 1, handkerchief friction plastic film on the role of shredded paper 2, handkerchief friction two plastic films, in close proximity to each other,
