The common classification accuracy of ECOC is used because the fitness operate of GA. The experimental results show that the multiclass classification methodology proposed on this paper can effectively predict the grade of efficiency, with an average accuracy rate of over 75%. The analysis results help to implement customized teaching for college students with completely different grades and learning patterns. Firstly, for accuracy, the average accuracy of college A is about 80%, whereas the common accuracy of college B is about 75% and the average accuracy of faculty C is about 74%. Secondly, for the encoding methods used in three information sets, the SR encoding method achieves the best accuracy, adopted by the DR encoding. With a view to identify the educational habits patterns, the k-means algorithm is adopted to cluster students with totally different studying behavior patterns from college A; combining the expertise of years in blended instructing, 4 typical studying habits patterns were discovered, as shown in Table 2. The same learning habits patterns can be found in colleges B and C, however the proportion of the 4 sorts of students is completely different from that of school A resulting from completely different information distribution.
