Abstract

<p>Body movement frequency seems to be one of better indicators to capture pupils’ engagement or on-task behavior for all of them in surveyed classrooms. This study investigated corresponding relationships between on-task behavior related body motions and body movement frequencies to be able to record pupils’ engagement or on-task behavior with using triaxial accelerometers. We conducted activities imitated classroom lessons for elementary school third and fifth graders, actuated pupils to make body motions in a manner 510 日本教育工学会論文誌（Jpn．J．Educ．Technol.） similar to general classroom lessons, measured triaxial acceleration due to pupils’ behavior promptly over time, and obtained body movement frequencies. We conducted the analysis of the range of the maximum value of body movement frequency with fitting the generalized extreme value distribution according to the category of on-task behavior body motion. The result showed the criteria for judging whether the behavior is taken for each category of pupils' body movements reflect engagement or on-task behavior engagement or on-task behavior. The result also indicated that the most of the body movement frequencies corresponding to off-task behavior are either close to 0Hz or over around 2.5Hz.</p>
