The document discusses time perspective and its relationship to learning in serious games and game-based learning environments. It defines time perspective as how individuals view the past, present and future. Previous research found that a balanced time perspective and stronger future time perspective can lead to higher academic achievement and motivation. The document aims to study how students' time perspectives influence collaborative learning processes and performance in serious games. It hypothesizes that students with similar time perspectives may perform better and learn more, and that games including time-related challenges could help students train their time competence.
