Teachers should interact actively with students in the course of teaching for the purpose of mutual development, deal with properly the relationship between knowledge impartation and ability cultivation, attach importance to students' independence and self-confidence, guide students to put forward questions, make investigation, search and study in practice and promote them to study in an active and individual way under the guidance of teachers. Study shows that there was a significant difference between student discipline scores of those who hold a bachelor degree and those who hold a under degree, which may imply that teachers holding advanced academic degrees tend to have a more open view of student discipline. Linear regression analyse was also used to infer the predictive power of demographic variables for teachers' beliefs, and the result showed that the number of years teaching and highest educational attainment both have predictive power in teachers' beliefs. There is a need of further study of teachers in colleges and Universities, administrative staff of educational departments, and administrators of schools
