Discovery education method is a teaching method based on problem learning, which means that when students learn concepts and principles, teachers do not directly provide students with learning content, but provide them with a problem situation, just give them some facts and questions, so that students can actively think and explore independently.
Its guiding ideology is to take students as the main body and realize the cognitive process independently. That is, under the inspiration of teachers, students consciously and actively explore scientific knowledge and methods and steps to solve problems; Study the attributes of objective things; Find out the reasons for the development of things and the internal relations of things, find out the laws from them, and form your own concept. Teachers play the role of learning promoters, guide students to ask questions about this situation, collect evidence by themselves, and let students find something from it.
