在新课标中,对数学进行了大范围的改革,不仅包括数学课程目标与结构的改革,还进行了教学方法与教材开发的改革,可谓是一次规模庞大、涉及面较广的改革。由于高中数学中的函数部分是数学中的纽带,这也是高中学生最难理解的部分。出于函数的重要性和复杂性考虑,本文将对新课改后的高中函数教学改革进行个案研究,以便及时发现其中存在的问题,并将问题进行及时改革。 In the new curriculum standard, a large-scale reform of mathematics has not only included the reform of the goal and structure of mathematics curriculum, but also the reform of teaching methods and textbook development, which can be described as a large-scale and extensive reform. Since the part of the function in high school math is a link in mathematics, it is also the hardest part of high school students to understand. Considering the importance and complexity of the function, this article will carry out a case study on the teaching reform of high school function after the new curriculum reform in order to find out the existing problems in time and reform the problems in time.
