This study focuses on understanding the influence of gamification factors on the level of engagement in the learning process of students at higher education institutions in Da Nang city. The quantitative study was conducted with a sample size of 237. SmartPLS software was used to evaluate the measurement model and structural model. The results show that Gamification elements, especially competition and challenge, have a positive influence on student attitudes toward using gamification in the classroom. This positive attitude also promoted student emotional and behavioral engagement, but had no significant impact on cognitive engagement. Theoretically, the research results contribute to expanding and enriching the content of the theory of planned behavior (TPB), a fundamental theory in explaining the relationship between attitudes and behavior. In addition, the study also brings important practical implications for the design and implementation of gamification applications in the context of higher education to promote engagement and improve student learning quality.
