Abstract: With the deepening of educational digitalization, the "Three-Teacher Classroom", which consistsof full-time teachers, student junior teachers and intelligent auxiliary platforms, provides a localized practicalpath for the reform of high school chemistry teaching. Taking Properties of Chlorine from Compulsory Volume 1of the PEP high school chemistry textbook as the research carrier, this paper constructs a three-phase teachingmodel of "situation perception-cooperative inquiry-transfer and innovation". Integrating the practical educationconcept and human-machine collaborative teaching strategy, it systematically sorts out the theoretical basis, roledivision, collaborative operation mechanism and classroom implementation process of the model. Teachingpractice shows that the model can effectively solve practical problems such as difficulties in carrying outhigh-risk experiments and superficial inquiry leaning in traditional chemistry classrooms. It facilitates thedevelopment of students' disciplinary core competencies in chemistry and offers referential practical samplesfor the intelligent transformation of high-school chemistry experiment courses.
