在数学教学中,我们经常会遇到不同的课型。例如:新授课、复习课、习题课、研究性学习课、讲评课(讲述并评议学生的作业或考卷上的试题的课型)等等。由于各个课型有各自的特点和方法,因此针对不同的课型,我们的目标、教学方法和侧重点也有所不同。然而在长期的教学中,我们发现,有许多教师只对某些课型十分重视,如:新授课、复习课、习题课,但是对讲评课却不够重视,甚至认为讲评课只需将作业或试卷上的题目讲完即可,不必备课。 In mathematics teaching, we often encounter different types of classes. For example: new classes, review classes, exercises, research studies, lectures (talking about and commenting on students’ assignments or exam questions on the exam) and so on. Because each class has its own characteristics and methods, our goals, teaching methods, and focus are different for different classes. However, in the long-term teaching, we have found that many teachers only pay attention to certain types of classes, such as new classes, review classes, and exercises, but they do not pay enough attention to lecture evaluation. They even think that the assessment class only needs to The questions on the test paper can be finished. It is not necessary to have a lesson.
