Abstract: The assessment standard of the learner-centered teaching evaluation steers from knowledge to ability. Using virtual learning communities as a E-learning platform, a community learners' ability fuzzy assessment model was set up, based on the characteristics of virtual learning communities and E-learning, combining personal ability, online cooperation ability and the test results. The assessment agrees with the membership vector of the comments. To narrow the fuzzy disparity, this paper made use of the information from the comprehensive evaluation to build a classification quantitative model, thus further quantifying the assessment to classify the students' ability more accurately.

Key words: Ability assessment, Membership vector, Classification quantitative
