A subcategory of computer-assisted instruction (CAI), games have additional attributes such as motivation, reward, interactivity, score, and challenge. This study used a quasi-experimental design to determine if previous findings generalize to non simulation-based game designs. Researchers observed significant improvement in the overall population for math skills in the non-game CAI control condition, but not in the game-based experimental condition. The study found no meaningful, significant differences in language arts skills in any of the conditions. This finding has implications for the design of future learning games, suggesting that a simulation-based approach should be integrated into the gaming technology.
