The average classification accuracy of ECOC is used as the fitness function of GA. The experimental results present that the multiclass classification method proposed on this paper can successfully predict the grade of efficiency, with a mean accuracy charge of over 75%. The analysis outcomes assist to implement personalised teaching for college students with completely different grades and studying patterns. Firstly, for accuracy, the common accuracy of faculty A is about 80%, while the common accuracy of college B is about 75% and the typical accuracy of faculty C is about 74%. Secondly, for the encoding methods utilized in three knowledge units, the SR encoding technique achieves the best accuracy, adopted by the DR encoding. So as to determine the learning habits patterns, the ok-means algorithm is adopted to cluster college students with different studying behavior patterns from school A; combining the expertise of years in blended teaching, 4 typical learning habits patterns had been discovered, as shown in Table 2. The similar studying conduct patterns can also be present in schools B and C, however the proportion of the 4 types of students is completely different from that of college A as a consequence of totally different information distribution.
