The modernization of education requires secondary school teachers to improve their information-based teaching ability, and applying MOOCs to secondary school geography classroom teaching is also a new attempt. Applying MOOCs to secondary school geography classrooms can change the traditional teaching mode and cultivate students' independent learning ability. This paper mainly explores the feasibility of applying MOOC to secondary school geography teachers in the classroom and proposes strategies for teachers to effectively improve their informational teaching ability and level in applying MOOC to teaching. At the same time, the teaching method of combining MOOC with the flipped classroom is proposed for the inherent shortcomings of MOOC itself. The article also discusses practical ways to improve secondary school geography teachers' information ability, including changing teachers' teaching concepts, strengthening teachers' training, increasing hardware investment, and building digital campuses. The study can provide a reference for current secondary school geography teachers to improve their ability and use of information technology and innovate classroom teaching modes and methods.
