Students are the main body of the classroom and the main body of learning.

With student activities as the main line, not only Inspiring students’ interest in participation can also activate students’ thinking and allow them to be effectively trained and promoted in their most recent development zone, so as to promote the consolidation of knowledge and skills, and the refinement of their abilities and ideas.
