The results show that: teaching quality can be evaluated by several important indices, namely, teaching attitude, teaching content, teaching method, and teaching effect; the most important indices are teaching attitude and teaching content, followed by teaching effect and teaching method. The index scores of professional education mode were much higher than those of general education mode. Teaching effect is the highest rated index among students of accounting, and teaching attitude is the highest rated index among students of business administration.
