The Effects of Fourier Series Game-Based Learning Activities on Industrial Education and Technology Students’ Mathematical Self-Efficacy

Self-efficacy is vital for the development of oneself since it is the belief that one could conduct the required actions to achieve the tasks given to them. At a particular University in Bangkok, Thailand, the students from the faculty of industrial education and technology attained the lowest score in almost every learning module among others, especially the module of Fourier Series, due to the lack of mathematical self-efficacy, which is important for the careers that involve scientific and innovative subject. Game-based learning is proven to be an effective pedagogy for improving self-efficacy since it provides the engagement, motivation, competition, and progression needed to foster self-efficacy. This study aims to improve students' mathematical self-efficacy through game-based learning pedagogy. The classes are on-site with online interactive broadcasting where the students could choose to participate in either manner. The participants were 33 out of 115 students who were willing to commit to the study chosen by volunteered sampling from our learning section. The data was collected through the mathematical self-efficacy questionnaire and semi-structured interview and analyzed using the Wilcoxon Signed-Ranked test and content analysis. The results indicated that the students’ mathematical self-efficacy was not improved due to students lacking the needed self-discipline toward learning. From the obtained result, we recommend the implementation of well-constructed classes that promote the students’ selfdiscipline for more precise observations of mathematical self-efficacy development
