Abstract. This article examines how interactive digital platforms influence student engagement and academic achievement in higher education. The paper argues that digital platforms are most effective when they are used not only as tools for content delivery, but also as environments for communication, collaboration, feedback, and active learning. Drawing on recent higher education studies, the article explains that interactive platforms can improve behavioral, cognitive, emotional, and social engagement when course design is clear and student-centered. It also discusses the connection between engagement and achievement, showing that timely feedback, peer interaction, flexible access, and meaningful tasks may support better academic results. At the same time, the article notes several limitations, including weak course design, low digital readiness, poor internet access, and the narrow use of analytics. The paper concludes that interactive digital platforms can strengthen learning quality in higher education if they are guided by pedagogy, teacher support, and balanced evaluation [1].
