A content-generation system that offers adaptive contents for each learner has been developed. In particular, it consists of an assessment function that utilizes a learner?s process of answering a question. The function can extract event data generated by each learner during an answering process to a question of a test given by PC via a digital pen, and it analyzes the event data in order to extract a learner?s answering process and pattern. Using this system, each learner can look back at their answering process in addition to look over the final answer. As a result, study efficiency is expected to be improved. Furthermore, the teacher or tutor can create custom-made content for each learner according to the answering process of each learner.
