The purpose of this study was to examine the effectiveness of a Karate trial teaching class in an initialteacher training course, through the student's formative assessment. It involved two case studies of trial teaching classes of Karate and that of two other activities, taught by the students of an initial teacher training course. The results were assessed using the Student's Formative Assessment of Physical Education Classes scale developed by Takahashi et.al(1994). Results of the study indicate that the students' formative assessment shows were significantly different (“new discovery”: p＜.05) and show a trend toward statistical significance (‘Skill growth': p＜.10, ‘Fun Exercise': p＜.10, ‘Learning friendly': p＜.10) based on the classes provided by Karate and other teaching materials. This implies that Karate might have different effects on the learning of students compared to other activities as teaching materials in school-level physical education
