STEM education is a general term for science, technology, engineering and mathematics education, but it is definitely not a general term for individual disciplines, but an interactive integration. In other words, it should be a bridge that can provide students with the opportunity to know the world as a whole, so that students can turn the scattered knowledge they have learned into an interconnected and unified whole, thus eliminating the obstacles that the knowledge of various disciplines is separated in traditional teaching and is not conducive to students' comprehensive solution to practical problems. It is an interdisciplinary learning method.

What does STEM education mainly educate children? There are mainly the following four points:

One is scientific literacy, that is, using scientific knowledge (such as physics, chemistry, biological science and geospace science) to understand nature and participate in the process of influencing nature;

The second is technical literacy, that is, the ability to use, manage, understand and evaluate technology;

The third is engineering literacy, that is, understanding the design and development process of technical engineering;

Fourthly, mathematical literacy, that is, students' ability to find, express, explain and solve mathematical problems in various situations.

Specifically, STEM education advocates a new teaching method: let students complete their own interesting and life-related projects, and learn various disciplines and interdisciplinary knowledge from the process. STEM is actually a change of traditional educational concept based on standardized examination, which pays more attention to the learning process rather than the results. In essence, we should dare to make students make mistakes, let them try different ideas and let them hear different views. Contrary to exams, children are expected to create knowledge that can be applied to real life.
