Outline of Final Research Achievements

In this study, we aim to clarify the relationship between writing behavior and learners' comprehension degree by using pen device. The pen device can sense writing behavior such as writing amount and writing speed. For 60 subjects, learners' comprehension degree estimation was performed by using an integrated evaluation method that evaluates accuracy by judging whether the answered question is correct or not and the confidence degree of learners' answer in combination. It is revealed that the average variation of the answer time and force of pen grip explains the learners' comprehension degree and learners' confidence affects on the force of pen grip. As a result of evaluating the accuracy of estimation of learners' comprehension degree, we obtained an estimation accuracy of 72.1% by combining the pen gripping force and correctness judgment from the answer sheet.
