据我观察 ,似乎很少有人会做数学课堂笔记 ,原因有二 :一是老师讲课速度快 ,来不及做记录 ;二是认为数学主要靠理解 ,不必记录 .然而好记性不如烂笔头 ,做一些精要的课堂笔记还是必要的 ,但我也不主张课堂记录类的笔记 .本人认为 ,数学课堂笔记 ,应当言简意赅 .一、对于纲领性? According to my observation, it seems that few people will take notes in mathematics classes for two reasons. One is that teachers are fast in class and have no time to make records; the other is that mathematics mainly depends on understanding and does not need to be recorded. However, good memory is not as good as writing and doing fine. The necessary class notes are still necessary, but I also do not advocate class notes. I believe that math class notes should be concise. First, for programmatic?
