高效课堂是广大教师共同追求的目标,物理学这门以观察和实验为基础的学科,要想达到高效课堂的标准,实验教学就显得尤为重要。人教版九年义务教育初中物理教材中有大量实验,有的看似简单,但由于可视度低、现象不明显、安全性差、操作复杂等因素,在实际操作中却并不容易成功,这就会直接影响教师的教学效果。在实验教学实践中,笔者从身边寻找实验物品,创新改进了几个实验,明显提高了课堂教学效果,现浅谈如下几例。 Efficient classroom is the common pursuit of the majority of teachers, physics, observation and experiment based on this subject, in order to achieve efficient classroom standards, experimental teaching is particularly important. There are a lot of experiments in the nine-year compulsory education junior high school physics textbook of the PEP, and some of them may seem simple. However, due to the low visibility, the phenomenon is not obvious, the safety is poor, the operation is complicated and other factors, it is not easy to be successful in practice. This will directly affect the teaching of teachers. In the experiment teaching practice, the author looks for the experiment article from the side, innovates and improves several experiments, obviously enhances the classroom teaching effect, now as follows several examples.
