Differences in Educational Effects of Instructional Materials for Traffic Safety Hazard Prediction Training by Media Type

Abstract

KYT (hazard prediction training, K: kiken (hazard), Y: yochi (prediction), T: (training)) has been promoted in Japan as a part of traffic safety education. Most of the conventional KYT instructional materials are in third person perspective and mainly use illustrative images. On the other hand, recent developments in VR-related technologies have made it possible to create a first-person perspective, 360-degree, all-round video VR instructional material. However, VR instructional material’s effectiveness for traffic safety education has not yet been fully investigated. In this study, we first created VR and photographic instructional materials, then randomly assigned 10 students to VR instructional material, photographic instructional material and a control group, and evaluated the educational effects of the instructional materials in an experiment. The results of the pre- and post-survey questionnaires revealed that 1) the most appropriate teaching materials differed depending on the learning items, and 2) photographic materials were the most effective overall.
