Purpose: The researchers discuss the debate of ideas (DoI) and student understanding conducted on questioning and student answers or discussions in game-based approaches and on DoI as used in the tactical-decision learning model. Literature Review: Literature regarding types of questions and expected student answers and questioning for learning in game-based approaches is reviewed. In addition, a brief overview of the context in which DoI was originally developed is presented. Findings and Discussion: Studies that used DoI are discussed with regard to the management of game play and observation, DoI content and the dynamics of student discussions, and impact on game play statistics and on students' tactical knowledge. Challenges for teachers and students are discussed, as a student-centered approach encourages changes in traditional teacher and student roles. Finally, the importance of understanding the internal logic of team sports for solving tactical problems and learning is discussed.
