当代教育不仅要给学生传授知识,更要注重学生综合能力的培养。而实验教学是培养学生基本素质和科学创造能力的重要环节,教师巧妙地利用身边的物品自制教具或者直接应用到实验当中,可让学生更深刻地体验科学与生活的真实性,以及更好地培养学生的动手能力、创造能力等。在教学实践中,笔者经常应用到下面两个优化案例,现整理出来,与同行交流分享。一、利用火柴进行短路危害的演示实验初中物理教材介绍到了短路,并介绍到了短路
Contemporary education should not only impart knowledge to students, but also focus on the cultivation of students’ comprehensive abilities. Experimental teaching is an important part of cultivating the students’ basic qualities and their ability to create science. Teachers skillfully use self-made teaching aids around them or apply them directly to the experiment so that students can experience the authenticity of science and life more deeply and better Cultivate students’ ability to create, and so on. In teaching practice, I often apply to the following two optimization cases, now sorted out, and share with peers. First, the use of matches to short-circuit the demonstration of harm Junior high school physics textbooks introduced to the short circuit, and introduced to the short circuit
