| Summary: | 碩士 === 國立臺灣科技大學 === 數位學習與教育研究所 === 107 === Researchers have pointed out the potential of educational computer games in improving students’ learning performances and learning perceptions. In this study, a collaborative game-based learning approach with a grid-based Mindtool is developed. To evaluate the effectiveness of this approach, an experiment has been conducted in a junior high school science course. The participants were two classes of eighth graders. One class with 29 students was assigned to be the experimental group, while another class with 25 students was the control group. The learning content is “knowing the elements” unit of the natural science course. The experimental results revealed that this approach increased the students’ cognitive load and decreased their group efficacy; moreover, the learning achievements of the two groups were not significantly different. Based on these findings, in-depth discussion was conducted.
