在数学教学过程中,教师要关注学生原有知识水平。原有知识水平可以是知识的,也可以是有关技能的或活动经验的,还可以是数学思想与方法,下面笔者就学生的起点问题在教学中做一些尝试与思考。一、了解学情,便于教学摸清学生知识储备,真正让教学工作更具实效性,做到有的放矢。实施前测,便于老师了解学生的知识储备情况,了解学生在新知学习中可能遇到的困难,并据此设计出适合学生的课堂教学方案,真正让教学工作落到实效。
In the process of mathematics teaching, teachers should pay attention to the students’ original knowledge level. The original level of knowledge can be knowledge, can also be related to skills or activity experience, but also can be mathematical ideas and methods, the author below the students starting point in the teaching to do some try and thinking. First, to understand the learning situation, easy to find out students knowledge of teaching reserves, the real teaching work more effective, to be targeted. The implementation of the pre-test facilitates teachers to understand the knowledge reserve of students, understand the difficulties that students may encounter in learning new knowledge, and design a classroom teaching program suitable for students accordingly, so as to truly enable teaching work to be effective.
