This document summarizes three dissertations on the topic of game-based learning. Dissertation 1 explored how task framing (learning only, play only, educational game) impacted student expectations, performance and enjoyment. It found that an educational game frame led to higher post-assessment scores without reducing enjoyment. Dissertation 2 investigated how students learned concepts like economics through playing simulation games. It found students valued and individualized their learning through game play. Dissertation 3 examined relationships between technology usage, video games and preferences for virtual learning environments. It suggested digital natives prefer more technology-infused learning over traditional lectures.
