Development of Digital Role-Playing Game on C Programming to Enhance the Academic Achievement and Skills of Grade 11 Students

Abstract

This study aims to 1) develop a digital role-playing game for C programming, 2) compare students’ academic achievement before and after learning through the digital role-playing game, and 3) compare students’ C programming skills after learning through the digital role-playing game with an 80% criterion. The sample consisted of 27 Grade 11 students at Ratchananthajarn Samsenwittayalai 2 School who were enrolled in the Computing Science 1 course during the first semester of the 2025 academic year. Cluster random sampling was employed. The research instruments included 1) an evaluation form to assess the appropriateness of the developed digital role-playing game, 2) an academic achievement test, and 3) a C programming skills assessment. The data were analyzed using appropriate statistical methods. The findings revealed that 1) expert evaluation indicated that the overall appropriateness of the developed game was at the highest level; 2) students’ academic achievement after learning through the digital role-playing game was significantly higher than their pre-learning achievement, with a very large effect size; and 3) students’ C programming skills after learning through the digital role-playing game were significantly higher than the 80% criterion at the .05 level of statistical significance.
