This article introduces the teaching strategy of the section “Discovery of auxin”: teaching is based on the “problem experiential” design. The teacher plays the role of director and allows students to participate in classroom learning as “scientists”. Learning and learning; teaching and learning by creating problem situations that stimulate students to actively participate in inquiry, setting questionable strings of questions, and instructing students to design inquiry experiments, allowing students to understand experimental design ideas in the process of auxin discovery Deeply, students’ ability to analyze and solve problems and experimental design capabilities are improved.
