Problem-based teaching mode is a teaching method that creates problems by taking problems as clues, emphasizing stimulating students' interest in autonomous learning, enabling students to master knowledge in problem-solving thinking activities, developing intellectual training skills, and cultivating students' ability to discover and solve problems independently.

For example, the geography teacher shows a picture and a statistical table of geographical data to stimulate students' interest and create a certain situation. Teachers ask questions and guide students to explore and solve problems. This way is the problem teaching mode.
