叶圣陶先生在谈到教师的主导作用时,曾这样说过:"我意如能令学生于上课之时主动求知、主动练习,不徒坐听教师之讲说,即为改进教学之一道。教师不宜以教课本为专务,教师指示必须注意之点,令自为理解,彼求之弗得或得之谬误,然后为之讲说。 When Mr. Ye Shengtao talked about the leading role of teachers, he once said: “I mean that if students can take the initiative to seek knowledge and actively practice when they are in class, they do not listen to the teachers and they are one of the ways to improve teaching. Teachers should not use textbooks as their own task. Teachers should point out that they must pay attention. They must be self-understanders, and they must be guilty of misunderstandings, and then talk about them.
