Validation of a Flow Scale for Online Physical Education Lectures Using Rasch Analysis

초록

The rapid expansion of online physical education (PE) has made it difficult to assess students' engagement in psychomotor activities. The flow scale used in this study was originally developed for face-to-face PE classes; its suitability for online instruction has not yet been tested. This study evaluated the scale's psychometric properties for online PE lectures using Rasch analysis of survey data from 416 South Korean university students enrolled in psychomotor PE lectures. Analyses of item fit, rating-scale functioning, item difficulty, person separation reliability, and differential item functioning supported a 27-item version with clear unidimensional structure and appropriate category use. The validated scale enables instructors and researchers to monitor students' engagement in online PE lectures, compare engagement across lectures or groups, and evaluate the impact of instructional strategies and technologies. These findings provide a measurement foundation for designing, refining, and researching online PE curricula.
