在备课时,教师往往在新授课方面下足功夫,认为新授课是教学新知识,马虎不得。而说起练习课,许多老师认为,就是让学生完成题目,不用备课,一节课讲到哪里算哪里。长期的教学习惯及对练习课价值的认识不足,导致学生对习题敷衍了事。近年,我在习题的内涵和外延方面做了一些实践,收获颇多,用学生的话说那就是:做习题,我在行! In preparing lessons, teachers tend to devote much effort to new lectures, believing that the new lectures are new knowledge in teaching and sloppy. Speaking exercises, many teachers think that is to allow students to complete the subject, do not prepare lessons, where a class talk about where to count. Long-term teaching habits and lack of understanding of the value of the practice class, leading students to perfunctory exercises. In recent years, I have done some exercises on the connotation and extension exercises, a lot of gains, in the words of the students that is: exercise, I am OK!
