随着科技的飞速进步，我们进入了人工智能时代，这对中小学阶段的人工智能教育提出了新要求，而机器学习是人工智能的关键技术之一，如何在中小学学段教授机器学习是一个非常值得探讨的问题。本论文的研究目标为构建一套适用于我国的以机器学习为内容的中小学人工智能课程体系，主要通过研究国内外中小学人工智能教育的发展状况和课程标准，确定各学段的教学目标、课程内容、教学方法、教学工具、课程评价方式，并设计课程案例，从而实现中小学机器学习课程体系的构建。本论文对我国中小学人工智能教育的研究具有积极意义，通过设计出科学完善的课程体系，给出各学段典型的教学案例，希望能够对中小学人工智能教育的研究者提供一定的参考。

With the rapid progress of science and technology, we have entered the era of artificial intelligence, which puts forward new requirements for artificial intelligence education in primary and secondary schools. Moreover, machine learning is one of the key technologies of artificial intelligence, so how to teach machine learning in primary and secondary schools is very worth exploring. The research target of this paper is to build a set of machine learning curriculum system for primary and secondary schools, which suitable for our country. By researching the development of artificial intelligence education worldwide and the curriculum standards, the paper determines the teaching goal, curriculum content, teaching methods, teaching tools, evaluation methods, and then designs curriculum cases. Thus, the construction of machine learning curriculum system for primary and secondary schools is achieved. This paper is of positive significance to the study of artificial intelligence education in primary and secondary schools in China. By designing a scientific and complete curriculum system and giving typical teaching cases of each learning section, it is hoped to provide some reference for researchers of artificial intelligence education in primary and secondary schools.
