目前由于升学考试的压力,不少教师在主观或客观广并不十分重视物理实验教学。因此,初中物理教学应十分注重实验教学,切实加强实验教学。通过观察物理现象,激发学生学习兴趣,培养他们的观察能力。兴趣是影响学习积极性的最直接的因素。那些新奇的、对生活有意义的知识和问题,能引起学生强烈的兴趣。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、产生条件和特征等。如在观察“摩擦起电”规象时,要提示注意:手帕摩擦过的塑料膜对碎纸屑有什么作用?手帕摩擦过的两块塑
Currently due to the pressure of entrance exams, many teachers in the subjective or objective wide emphasis on physics experiment teaching. Therefore, junior high school physics teaching should pay great attention to experimental teaching, and practically strengthen experimental teaching. By observing the physical phenomenon, to stimulate students interest in learning and develop their observation ability. Interest is the most direct factor affecting the enthusiasm of learning. Those novel, life-giving knowledge and questions can arouse students' intense interest. When observing these physical phenomena, teachers should guide students to pay attention to the whole process of phenomena, conditions and characteristics. As in the observation “friction electrification ” regulation, to be prompted to pay attention: handkerchief friction plastic film on the role of shredded paper? Handkerchief friction of the two plastic
