The key to implementing the enlightening principle lies in mobilizing students' enthusiasm and initiative. Teachers should not only give full play to the leading role of teachers, but also reflect the subjectivity of students. We should encourage students to be curious and think positively, guide them to think positively and negatively, and let them learn to reason by themselves and get the correct answer. Teachers should not only teach students a certain knowledge point in class, but also use their own knowledge to explore new knowledge. That is, the heuristic teaching method of "drawing inferences from others" is often used. In a word, heuristic teaching requires teachers to let students learn consciously, not passively, and cultivate students' learning will. Teachers should not force them to study, but should give guidance in the process of thinking, but should not take the place of students to draw conclusions. They should cultivate students' ability and habit of independent thinking.
The heuristic principle reflects the objective law of the teaching process. The useful theory of students' learning is not a passive mechanical pile-up, but a complex process in which students think, speak and do things themselves, from perceptual to rational, from quantitative change to qualitative change. In other words, this process can only be realized when students think independently. Only when students can consciously study all subjects, have a proactive spirit and a strong interest in learning can they learn well. Putting forward the enlightening principle is the inevitable requirement of China's educational purpose. Therefore, teachers are required to be good at inspiring students in teaching, so that students can have the enthusiasm and initiative of autonomous learning and effectively complete teaching tasks.
