The new curriculum reform has put forward more new requirements for the teaching of junior high school mathematics in the classroom, and a variety of advanced teaching concepts, teaching modes and teaching methods have emerged in the field of secondary school teaching, aiming to achieve the classroom goals of paying attention to student development, emphasizing teacher growth, and teaching by learning. Among them, the 5E teaching model, as a new teaching model, can effectively promote the transformation of traditional classrooms into "student-centered" classrooms. Taking the quadratic function of Beijing Normal University as an example, this paper discusses how to design junior high school mathematics teaching based on deep learning theory and 5E teaching mode as the carrier, so as to help students improve their deep learning ability and improve their learning thinking ability.
