1. Stimulating students' learning motivation and curiosity, cultivating students' curiosity and mobilizing students' learning enthusiasm and initiative are important conditions to help students form and develop their creative thinking ability. Students' learning motivation and thirst for knowledge, learning enthusiasm and initiative will not naturally occur, but depend on the teaching situation created by teachers. Since ancient times, teachers have created two teaching situations: injection and heuristic. The former means that students' learning depends entirely on the teacher's explanation, while passive learning can't stimulate creative thinking at all. The latter is to create problem situations, arouse the enthusiasm and consciousness of students' thinking activities, and make students' learning process become a process of active exploration.
