In China, the main goal of basic education curriculum reform is to develop students' key competencies. The physics teaching directed by key competencies would not only aim at the memory and reappearance of physics knowledge but also the application of physics knowledge and methods. As teachers who guide students' learning and implement teaching activities, the improvement and development of their key competencies plays an important role in the development of students. The key competencies of physics teachers consist of physics literacy, education and teaching literacy, scientific literacy, humanistic literacy, information literacy, and life-long learning ability.
