学生由小学升入初中,进入了新的学习环境,会遇到许多不适应的问题,诸如课程设置、知识衔接、教师讲课方法等。同时,学生又处于由形象思维向抽象加强思维的过渡阶段,这就需要有一个正确的、有效的引导过程。因此,优化初中起始阶段的数学教学,打好初中数学基础,是每位数学教师应该引起重视的课题。 Students from junior high school into junior high school, entered a new learning environment, will encounter many problems not suited to, such as curriculum, knowledge convergence, teacher lectures and so on. At the same time, students are in the transitional phase of strengthening their thinking from the image thinking to the abstract, which requires a correct and effective guiding process. Therefore, optimizing the mathematics teaching in the initial stage of junior middle school and laying the mathematical foundation of junior high school are the topics that every mathematics teacher should pay attention to.
