ABSTRACT
Observed from the classroom ecology perspective,the assessment index of classroom teaching quality in higher institutes examines only the teachers' teaching behavior, but the students' behavior,the classroom's ecological media and environment,which have great impact on the teaching quality,are excluded.Ecological analyses of typical cases indicate that the assessment index of classroom teaching quality in practice are not all-sided, and there are various factors affecting the justice of the assessment result, making it very difficult to obtain objective result. Therefore, two principles in applying the assessment result are to achieve ecological harmony by aiming at improving teaching through assessment and weakening its proving function, and to create an ecologically harmonious environment on campus that may promote teacher development and improve the teaching quality.
