过去我钻研教材,对习题部分是忽视了的。因此在课堂教学中对布置作业这一环节,有时流于形式,每每一堂课因时间不够,就随便把布置作业的几分钟挤掉了;或者时间够,因为备课时没有很好的钻研习题,也不明白应该如何指导学生做作业,就设法等到下课时间,随便交待一声:“做哪一面哪一个习题。”就草率收场。由于忽视习题的钻研与布置,学生反应做化学练习枯燥呆板,不感兴趣,造成学生做习题不认真的态度。另一方面,由于教师缺乏指导,学生不了解题目的要求,做成了似对非对的答案送上来,造成学生不能通过习题来巩固和复习新旧知识的重大缺陷。
In the past I studied textbooks, the part of the exercises is ignored. Therefore, in the classroom teaching arrangement of this part of the job, sometimes in the mere formality, often a lesson due to lack of time, just a few minutes to lay out the homework squeeze out; or time enough, because preparation is not a good study of exercises, Do not understand how to guide students in homework, try to wait until get out of class time, casually put it: “Which one to do exercises.” Due to ignoring the study and placement of exercises, students respond to chemical drills dull, not interested, resulting in students do not exercise serious attitude. On the other hand, due to lack of guidance from teachers, students do not understand the requirements of the subject and make right-to-wrong answers. As a result, students can not consolidate and review major defects in new and old knowledge through exercises.
