Abstract In the teaching design stage, firstly, the understanding research of atomic structure discipline is carried out. By explaining the two original problems of how to understand the composition of atoms based on the atomic nucleus and how to understand the structure of atoms based on the movement of electrons outside the nucleus, the atomic structure model of large concepts of the subject discipline is understood in an original and structured way. Then, from the aspects of teaching objectives and teaching ideas design, teaching implementation process, students' harvest, teachers' reflection and expert evaluation, this paper systematically presents the research process of “competence-oriented” and “exploring atomic structure based on scale” classroom teaching based on discipline understanding.
