Abstract Universities are looking for solutions to engage more students in STEM domains and enhance their learning performance (LP). In this context, gamification is put forward as a solution achieve aim. The present study examined the effect of – building on leaderboards ‐ LP. Furthermore, mediating variables, such intrinsic motivation, self‐efficacy, engagement, background sex, previous gaming experience, undergraduate major, were considered. A pretest‐posttest quasi‐experimental design...

The demand for professionals with expertise in Science, Technology, Engineering, and Mathematics (STEM) continues to grow. To meet this demand, universities are actively seeking strategies engage more students STEM disciplines improve their learning outcomes. One promising approach is gamification, specifically using leaderboards. This study investigates the impact of leaderboard-based gamification on performance 175 a calculus course, focus mediating roles autonomous motivation...

Abstract Despite the success of academic advising dashboards in several higher educational institutions (HEI), these are still under‐explored Latin American HEI's. To close this gap, three different universities adapted an existing dashboard, originally deployed at KU Leuven to their own context. In all cases, context was main ruling factor adaptations. paper, we describe adaptions using a framework that focuses on four elements context: Objectives, Stakeholders, Key moment and Interactions....

Abstract In Latin American universities, Learning Analytics (LA) has been perceived as a promising opportunity to leverage data meet the needs of diverse student cohort. Although universities have collecting educational for years, adoption LA in this region is still limited due lack expertise and policies processing using data. order get better picture how existing data‐related practices might affect incorporation institutions, we conducted mixed methods study four (two Chilean two...

One main objective for software developers is to find the right approach design and develop a tool faster effectively. In context of Learning Analytics (LA) in Latin America, this becomes more complicated due lack clear guidelines that could guide Higher Education institutions (HEI) LA tools. Thus, study describes step by methodology tool. The combines phases Design Thinking testing components Human-Computer Interaction theory. It starts from LALA framework, set methodologies guides HEI...
