Abstract

In the field of outdoor education, learning evaluation is a challenge, as the conventional method, which is subjective evaluation, can be inaccurate. This study attempts to overcome this challenge by evaluating learning using motion sensors. Considering that the moment when a learner moves his or her head during a lecture encompasses important information related to concentration, we measure the concentration of the learner using the angular velocity information of his or her head. However, it is not clear based on the information obtained from only one learner whether the cause of the movement is actually a change in his or her concentration level. Therefore, we propose a method for distinguishing the concentration of learners by comparing head movements in the entire learning group. To confirm the effectiveness of the proposed method, we measured the angular velocity of the learners’ heads in outdoor education by attaching an angular velocity sensor to them. In the lecture-induced gaze direction, the head movement timing of many learners coincided after gaze induction timing. In addition, we found that the learners with higher levels of concentration did not move their heads, except at the time of gaze induction.
