The design of Part 2 is to measure the participants’ ability to associate and analyze similarities and differences. Unfortunately, the results in this part are not as impressive as expected. According to the results, there is no statistically significant difference in Part 2, and the scores of the experimental group are only slightly better than the scores of the control group. Consequently, computer-based video game playing did not much improve participants’ judgment. Two explanations are possible for this result: (1) insufficient descriptions or explanations of each key concept in the computer game, thus the participants in the experimental group did not have enough information to analyze and compare the differences, (2) the depictions of each item in Part 2 was not simple and easy enough for third graders to understand. Therefore, they were confused in making the right choice.
