Transparency emerges as an important issue that aims to makestudents aware of educational processes and contents. This research purpose is to study pedagogical transparency in the context of the use of gamebased learning (GBL). Transparency in pedagogy aims to improve the quality of teaching, and the relationship between student, teacher and teaching methods. In the GBL context, transparency use appears through an experiment that allows a better comprehension of the results obtained, providing support on the educational effect of the use of games. Evaluations with different groups of students were carried out to determinate the effectiveness of the proposal and the results indicated the efficacy of this approach, where i concurred to pedagogical transparency.
