近几年在听课中发现,有的青年教师对于课本的教学不够深入,认为”课本知识简单,例题、习题无深度,讲起来没滋味”,因此便蜻蜓点水式地照本宣科,然后一味漫无边际地搞题海战术,结果事倍功半,师生情绪受挫,阻碍了教学效果的提高.事实上,课本如同一块压缩饼干,其中蕴藏着丰厚的知 In recent years, I discovered in class that some young teachers did not have enough depth in the teaching of textbooks. They thought that “the knowledge of textbooks is simple, the examples and exercises have no depth, and they don’t speak much about them”, so they take a few words and follow the script, and then they go blindly The tactics of the sea resulted in less effective results. The emotional frustration of teachers and students hindered the improvement of teaching effectiveness. In fact, the textbook is like a compressed cookie, which contains rich knowledge.
