我们在听课中发现,有经验的教师总是抓住例题来传授基础知识和巩固基础知识,把例题教学作为培养学生能力、发展学生智力的重要途径。但有的教师在教学中,认为例题简单,让学生看一看了事;也有的教师因对例题缺乏钻研,在讲授例题时,只是把例题和解答机械地抄写到黑板上,不作讲解,甚至有的教师干脆删掉一些基本例题,这样就违反了由易到难、由浅入深的教学原则。总之,轻率地处理教材中的例题,必将会给学生的学习带来很多困难,以致造成学生基础知识不牢固、数学概念模糊不清的后果。我们在一所乡村小学听课,教师新授课后,我们出当 During the lectures, we found that experienced teachers always grasp examples to teach basic knowledge and consolidate their basic knowledge, and take the example teaching as an important way to develop students 'abilities and develop students' intelligence. However, in teaching, some teachers think that the examples are simple and allow the students to take a look at the situation. Some teachers, for lack of study on the examples, are only mechanically copying the examples and answers to the blackboard for explanation. Some teachers simply delete some basic examples, thus violating the teaching principle from easy to difficult and from shallow to deep. In short, the dishonest treatment of the examples in the textbooks will surely bring many difficulties to the students 'learning, resulting in the underdeveloped students' basic knowledge and the unclear mathematical concepts. We attended classes in a rural primary school, and after the teacher gave the new class, we went out of business
