近年来,随着新课程标准改革的有效推进,初中数学教科书情境的设计逐渐成为数学教育工作者面临的重要课题。要设置好课堂的教学情境是很重要的数学教学手段。本文旨在以实际案例系统探究初中数学教科书情境设计的方法。一、设计知识迁移的数学情境,用旧知识解决新问题初中数学中有不少典型的知识迁移运用的知识点,即使并未学习过,但只需要用原有知识的积累,就可以运用已有的知识去解决新问题,教师要注意在课堂先让学生复习、练习以前相关知识的题目,再来引入新概念和知识点。例如在讲解初中数学教科书一元一次不等式的解法时,学生们以前并
In recent years, with the effective promotion of the reform of the new curriculum standards, the design of junior high school mathematics textbook context has gradually become an important issue for math education workers. To set the classroom teaching situation is very important mathematical teaching methods. The purpose of this paper is to explore the way of designing junior high school mathematics textbook context using the actual case system. First, the design of knowledge transfer mathematical situation, with the old knowledge to solve new problems There are many typical junior high school mathematics knowledge transfer knowledge points, even if not learned, but only need to use the accumulation of the original knowledge, you can use the Some knowledge to solve new problems, teachers should pay attention to students in the classroom first review, practice the previous knowledge of the topic, and then the introduction of new concepts and knowledge points. For example, in explaining junior high school mathematics textbooks once inequality solution, the students and
