物理是以实验为主的学科,但实验不仅仅是向学生展现一些物理现象和实验结果。一些有经验的教师往往善于挖掘和利用物理实验的价值作用,并运用到教学实践中去,既达到传授知识的目的,又可以激发学生的学习兴趣、培养学生的学习意识和学习能力。笔者结合教学实践经验,对物理实验的作用提出以下几点认识,以便得到更多的交流。一、通过物理实验教学激发学生的学习兴趣初中学生的年龄特点告诉我们,他们对新鲜事物表现得非常好奇,容易接受新事物,他们的学习动机或兴趣在很大程度上是依靠满足自己的好奇心和自我爱好来实现的,而初中物理是他们学习生活中第一次真正接触的专业学科,对物理学习内容及其现象都充满好奇,此时,对于他们而言,物理实验中那些千变万化的现象正是物理学科的魅 Physics is an experiment-based discipline, but experiments are not just about presenting students with some physical phenomena and experimental results. Some experienced teachers are often good at digging and exploiting the value of physics experiments and applying them to teaching practice, which can not only achieve the purpose of imparting knowledge, but also stimulate the students’ interest in learning and cultivate their learning awareness and learning ability. The author combines the teaching of practical experience, the role of physical experiments put forward the following understanding, in order to get more exchanges. First, through the physics experiment teaching to stimulate students’ interest in learning Age characteristics of junior high school students tell us that they are very curious about new things, easy to accept new things, their motivation or interest to learn largely to meet their own curiosity Heart and self-love to achieve, and junior high school physics is the first real contact in their learning life discipline, the content of the physical learning and its phenomena are curious, at this time, for them, the ever-changing physical experiments Phenomenon is the charm of physics
