Conclusions: The results allow us to conclude that gamification is an encouraging approach with which to teach C programming, a finding that is aligned with previous empirical studies concerning gamification on programming courses, carried out in academic contexts. Nonetheless, we are aware that further validation is also required to corroborate and strengthen the findings obtained and to investigate whether the kind of gamified elements (mechanics, dynamics, and aesthetics) used have any influence on students' performance, among other issues that deserve further investigation and that are explained throughout this article.
