美国为了培养科技人才提出了STEM教育，而后发展为STEAM教育，我国教育学者在引入STEAM教育概念时，根据我国基本国情与教育理念，提出了A-STEM教育。A-STEM教育理念提出不到四年，有关A-STEM教育理念的研究和案例还寥寥无几。本文基于A-STEM教育理念，对人教版初中物理《质量与密度》单元进行教学设计，并以福建省厦门市初二学生为教学对象进行了教学实验，研究初中生对于A-STEM课程的学习兴趣以及A-STEM课程对初中生的学习效果影响。

In order to cultivate scientific and technological talents, STEM education was put forward in the United States. And then STEM education developed into STEAM education. When Chinese educator generalized the concept of STEAM education, they proposed A-STEM education according to fundamental realities of the country and educational concepts of China. A-STEM education put forward less than four years of time. There is little research and case study about A-STEM education. In this article, the teaching design of Quality and Density is carried out. The teaching experiment was carried out with the second grade students in Xiamen, Fujian province as the teaching objects. To study junior high school students' interest in A-STEM courses and the influence of A-STEM courses on the learning effect of junior high school students.
