According to the results of post-test scores, computer-based video games can clearly facilitate students’ learning performance. This finding indicated that computer-based video game playing not only can improve participants’ fact differentiation/recall processes, but also promotes problem-solving skills by recognizing multiple solutions for problems. Additionally, more precise effects were detected by breaking the post-test scores into three sub-categories. When the researchers developed the items in Part 1, the objectives were to make the participants recall key facts, definitions, and concepts. As the results of Part 1 indicate, the participants in the experimental group have a better understanding of factual materials and concepts. Consequently, for finishing their mission, the participants in the experimental group know they have to memorize the key facts or concepts even if they were just playing a game.
