Abstract: In order to solve the problem of discrete knowledge，poor systematization and poor applicability of knowledge model in online learning platform． We propose a knowledge model based on knowledge map，and then use the FP-Growth data mining algorithm to mining association rules to update knowledge model．Practice shows that the knowledge map can effectively improve the systematicness of the knowledge model． The FP-Growth algorithm fully considers the influence of student factors on the knowledge model and improves the applicability of the model．
