一位老教师对备课打了一个十分贴切的比喻:如果教师想给学生一杯水,那他至少要准备好一桶水。这个比喻说明,教学效果的优劣与教师备课是否认真、充分有极大的关系。备课是一项复杂的教学准备活动,这其中需要教师认真细致地考虑各种有关教育因素,付出辛勤的劳动,才能在课堂上获得预期的、满意的效果。 An old teacher played a very apt analogy with lesson preparation: if a teacher wants to give a glass of water to a student, he should at least get a bucket of water ready. This metaphor shows that the pros and cons of teaching effectiveness and teacher preparation is serious, fully have a great relationship. Preparation is a complex preparation for teaching activities, which requires teachers to carefully consider all kinds of relevant educational factors, hard work, in order to get the desired effect in the classroom.
