课改后用的新教材看起来课本薄薄的,似乎没多少内容,其实不然,现在的课本上的内容大多是旧教材的浓缩。都说浓缩的是精华,学生只掌握精华部分就可以了。但事实并非这样,精华部分学生应该掌握,可对教材不理解,光掌握那部分不起作用,到时做起 The new textbooks used after the curriculum reform seem to be thin, it seems that there is not much content, in fact, the current textbook content is mostly the concentration of old textbooks. It is said that the enrichment is the essence, and students can only grasp the best part. However, this is not the case. The elite students should master it. They may not understand the teaching materials. The light control will not work.
