对于初中物理这样具有实践性的课程,没有演示实验的课堂是不可想象的。演示实验在初中物理课堂教学中的地位和作用是毋庸置疑的,但在教学实践中,因学校条件和学生素质的限制,很多实验无法按照“预期计划”进行,这就需要教师在教学中从学校实际出发,从学生实际出发,对演示实验进行改进,从而达到以实验促知识构建、以实验促能力形成的目的。
For such practical courses as junior high school physics, it is inconceivable that no experimental classroom should be demonstrated. Demonstration experiment in junior high school physics classroom teaching position and role is beyond doubt, but in teaching practice, due to school conditions and student quality limitations, many experiments can not be in accordance with “expected plan ”, which requires teachers in teaching Starting from the actual school, starting from the students, the demonstration experiment to improve, so as to promote the construction of knowledge to promote the formation of experiments to promote the purpose.
