Abstract: According to the characteristics of the virtual learning community，this paper assesses its effectiveness combining the learners’ enthusiasm，knowledge and ability.Since current assessment models mainly deal with the results of online tests，a fuzzy integrative model is set up based on mutual，cooperative and independent learning.According to the index of online learning activities，an independent study evaluation submodel is established.In order to accurately distinguish students and narrow the fuzzy disparity and the distortion caused by the maximum member theory，a more appropriate submodel is here put forward on the basis of online learning activities.It suggests a member quantitative model to further quantify the member vector resulting from the knowledge level and ability assessment submodel，to update the former elementary model.Comparisons and analysis are also made.
