This paper proposes an education support system for one-to-one or face-to-face education environment. In this system, each of teacher and student has his/her own pen tablet PC and uses it as an electronic notebook. Writing and erasing actions of them on the notebook are recorded with timestamp and played back as they want. Furthermore, the proposed system showed the modified area and paused point by the student on the notebook. It should be useful for the teacher to know where his/her student made mistakes or felt difficult to solve a problem. This information might be able to get from erasing and pausing points but it is difficult to grasp all these points from normal paper notebooks. However, with our proposed system, the teacher can grasp easily his/her student's erasing and pausing point and know the reason of such action by using the playback function. The experimental result shows that the proposed method can allow participants to grasp easily and correctly where the student made mistakes and felt difficult.
