ANALYSIS OF THE EFFECTIVENESS OF INTRODUCTORY EDUCATION THROUGH HAMMERING SOUND INSPECTION PRACTICE USING A SMARTPHONE APPLICATION

Abstract

 In introductory infrastructure maintenance education, tacit inspection skills must be made learnable through experience. We implemented a four-session hammering sound inspection program for university students using a smartphone application and evaluated educational effects with a 19-item questionnaire. Results showed that many participants gained understanding and perceived sound differences, with visualization supporting comprehension; the combined on-site/classroom/video format produced the strongest outcomes, while classroom-centered sessions still yielded meaningful gains. These findings suggest that layered experiences are important for strengthening inspection awareness, and the program can be adapted to constraints in practice; future work should consider expansion to municipal training and supplementary theoretical materials with follow-up support.
