To improve lessons in accordance with students’ comprehension levels, evaluation of teaching performance has been carried out by questionnaire and lesson study. However, lesson study in the context of faculty development is difficult for participants to spend long time for classroom observation and reflective discussion. Even if they have time for discussion, unfocused discussion often causes less fruitful and mutual understanding. We are developing an annotation tool not only to solve the above-mentioned time and space constraint but provide benefits owing to archiving lessons and their reviews. We design a pen-based annotation tool by which reviewers can write comments and draw marks onto on-line and off-line movie of class observation. The details of the annotation tool and user feedback from preliminary experiment in actual classrooms are described in this paper.
