做好预习工作,对提高课堂教学的质和量,无疑是十分有益的。因此,大多数教师都很重视抓学生的课外预习,有的还布置了大量的预习作业。殊不知这样一来,大大加重了学生的课外负担。试想,一位中学生每天要预习五、六门课程,少算些,每门课花十五分钟,那么光花在预习新课上的时间就要一个半小时左右,还要复习旧课,完成课外作业等等,这样沉重的负担,哪个受得了!
To do a good job of preparatory work, to improve the quality and quantity of classroom teaching, is undoubtedly very useful. Therefore, most teachers pay great attention to grasping students' extracurricular excercises, and some also arrange a large amount of preview work. As everyone knows, this greatly increased the extracurricular burden on students. Imagine, a high school students to preview five or six courses a day, less, fifteen minutes for each class, then the light in the preview of the new class time will be an hour and a half, but also to review the old class, completed Homework, etc., so heavy burden, which can stand it!
