This Paper aims at cognitive modeling of student learning using E-Portfolios created by learners after accessing learning content prepared based on the learning styles of the learners. As the E-Portfolio is the creation of one's own learning, it will be possible to judge the cognitive style of the learner. The E-portfolio created is analyzed based on the cognitive modeling principles like knowledge tracing, model tracing and prototyping. The result can be used for career counseling and talent scouting. This project can support on-line education systems in judging the learning patterns of the learners and offering a self-evaluation. © 2017 Elsevier B.V., All rights reserved.
