Research on the Network Teaching Mode of PBL Project Teaching Method

The construction of learning team facilitates the development of cooperation learning and interaction learning. Construction of appropriate learning team has an important significance for improving learning effect. This article introduces social network analysis method to establish the learner characteristic model with multi-dimensional indexes of comprehensive learning capacity, learning status and cooperation ability; use excellence, activeness and influence to conduct quantitative analysis; apply fuzzy similarity relation and fuzzy equivalence calculation to conduct the multi-layered fuzzy dynamic clustering to the learner, so as to identify the candidate learning; and based on it, achieve the division of learning team in iteration mode through mixing multi-type learners. The experimental analysis shows that the method in this article can significantly improve the accuracy of team division and the self-adaptability in virtual learning community, and facilitate the overall improvement of knowledge level, learning initiative and cooperation ability of all learners.
