作为高中化学教师,在课堂教学过程中会遇到各种各样的困难和问题,其中一个重要的问题是感觉化学教学任务重、课时紧,完不成教学计划。因此,如何在有限的时间内让每个学生轻松、愉快地取得学业和能力的双丰收呢?我认为,解决这一问题的关键就在于作业布置的有效性。 As a high school chemistry teacher, he encounters a variety of difficulties and problems during the classroom teaching. One of the most important problems is that he feels that chemistry teaching tasks are heavy, class time is tight, and his teaching plan can not be completed. Therefore, how to make every student enjoy the double harvest of academic ability and ability easily and happily within a limited time? I think the key to solving this problem lies in the effectiveness of the assignment.
