The results are presented based on the research hypotheses. The first sub-section provides the results related to the two primary hypotheses on participants' mathematics achievement and motivation together because one MANCOVA test was run to test both hypotheses. In addition, further analysis of the achievement and motivation data is provided as post hoc analysis. The second sub-section presents the results of the third hypothesis on effects of individual differences (i.e., prior mathematics knowledge, English language skill, and computer skill) on achievement and motivation of the participants when they played the games.
