| Outline of Final Research Achievements |
Recently, ITS(Intelligent Tutoring Systems) has been widely used, these systems has allowed the collection of huge amounts of educational data, such as examination results or studying behavior of students. In this study, we extract latent skills to master programming technique from the point of view of EDM (Educational Data Mining).
Our studies applied NMF(non-negative matrix factorization) method to decompose the results of an examination into a Q-matrix and another matrix. The Q-matrix is the relationship between
items and skills. Our proposed method could extract and visualize latent skills of students.
