Make students think in the most active, most active and most active state, and fully mobilize the enthusiasm and initiative of student learning. In the study, we can use the exploratory experiment to stimulate the students ’interest in learning, demonstrate the experiment to stimulate students’ interest in learning, model construction to stimulate students ’interest in learning, investigate activities to stimulate students’ interest in learning.
