随着教育体制改革和课程改革的不断深入，中国初高中数学教育面临
着新的挑战和机遇。其中，函数作为初高中数学教育的重要内容之一，对学生的数学素养和学习能力有着重要的影响。然而，初高中数学函数部分的教学中存在一定的衔接问题，学生在学习过程中存在着相应的困难和挑战。

本文通过对国内外相关文献和国内人教版初高中数学教材内容的分析，并通过发布问卷调查高一学生函数学习现状，深入研究了国内初高中学生面临的数学函数部分学习的衔接问题。首先，本文基于教材介绍了初中数学函数和高中数学函数的主要内容和重难点，分析了两者之间的联系和差异。其次，依据相关心理学理论分析了研究初高中函数衔接现状的意义。进而借助问卷调研的方式对学生进行调查，具体了解高一学生数学衔接现状与函数学习情况。最后，本文提出了一些解决初高中数学函数部分衔接现状的建议和措施，包括教师的教学策略、学生自主学习等方面。

With the deepening of education system reform and curriculum reform, mathematics education in middle and high schools in China is facing new challenges and opportunities.Among them, function, as one of the important contents of mathematics education in middle and high school, has an important influence on students' mathematical literacy and learning ability. However, there are some cohesion problems in the teaching of mathematics function part in middle and high school, and students have corresponding difficulties and challenges in the learning process.

Through the analysis of the relevant literature at home and abroad and the content of middle and high school mathematics textbooks, and by issuing a questionnaire to investigate the function learning status of senior one students, the connection problem of the mathematics function learning faced by middle and high school students in China. First of all, this paper introduces the main content and difficulties of junior middle school mathematics function and senior high school mathematics function based on the textbook, and analyzes the connection and difference between the two. Secondly, according to the relevant psychological theory, the significance of studying the current situation of middle and high school functions is analyzed. Then, with the help of questionnaire survey, students are investigated to understand the current situation of mathematics cohesion and function learning. Finally, this paper puts forward some suggestions and measures to solve the current situation of middle and high school mathematics functions, including teachers 'teaching strategies, students' independent learning and so on.
