The survey from the H college shows that learning power of college students is decreasing with the increase of grade, and the level of interactive learning is the lowest; there are four types of learning powers,excellence,standard,tradition and passivity and the learning outcomes with different learning types are significantly different; learning motivation has less direct influence on the learning of college students while attitude,interactive learning and learning strategies have a significant positive impact on learning a- chievements. Colleges and universities should strengthen the guidance for college students'learning power according to their types and grades,promote the interactive learning of college students in and out of class and improve teachers' incentive evaluation for college students in order to enhance college students'perception of learning outcomes.
