Programming knowledge tracking method fusing code and score information

The invention discloses a programming knowledge tracking method fusing codes and score information. The method comprises the following steps that historical programming behaviors of college students are expressed as historical coding events in an online judgment system OJ; inputting each programming problem in the student programming behavior data set into a problem representation module, and uniformly generating a problem representation containing knowledge points and difficulty information for each programming problem; the code representation module uses a pre-training technology to construct a supervised pre-training task to train the code representation module, and in the training process, codes submitted by college students, programming problems and problem representations of the programming problems are fused to generate enhanced code representations; inputting the problem representation and the enhanced code representation of the programming problem into a double-sequence modeling module, and performin
