初高中数学在难度、知识量和学习方式上都有很大差别。初中数学内容较通俗易懂,直观形象,对抽象思维能力要求不高。而高中数学教材较多的研究的是变量,需要学生具有较强的抽象思维能力。因此学生进入高中后,存在一定的学习困难。作为教师,有必要对初高中数学衔接教学进行研究。本文着重探讨一元二次函数的初高中衔接教学。1加强二次函数初高中衔接教学的必要性1.1二次函数在高中数学具有举足轻重的地位。二次函 Early high school mathematics in the difficulty, knowledge and learning methods are very different. Junior high school mathematics content more accessible, intuitive image, the ability of abstract thinking is not high. The high school mathematics textbooks are more variables of study, students need to have a strong ability of abstract thinking. Therefore, students enter high school, there is a certain degree of learning difficulties. As a teacher, it is necessary to study the teaching of math convergence in junior high school. This article focuses on the primary high school cohesion teaching of one dollar quadratic function. 1 to strengthen the secondary function of the need for cohesion teaching in high school 1.1 quadratic function in high school mathematics plays a decisive role.
