长久以来物理课给人的印象就是“难” ,教师觉得难教 ,学生感到难学。难字当头 ,影响师生情绪 ,以致教与学失去和谐 ,使得原本十分动人的教学过程变得古板 ,变得乏味。其原因就是 :教师把教材中与生活密切相关的内容 ,硬性地、机械地与生活割裂开来 ,使物理教学过程失去了生活 The impression given by the physics class has been “difficult” for a long time. Teachers find it difficult to teach and students find it difficult to learn. Difficulties in the word affect the emotions of teachers and students, resulting in a loss of harmony between teaching and learning. This makes the teaching process, which was originally very moving, old and boring. The reason for this is that teachers cut the contents of their teaching materials that are closely related to their lives, hardly and mechanically, and cut their lives, making the physics teaching process lose their lives.
