From the experimental results, it was found that, before the learning activity, the mean values and standard deviations of the students’ ratings of the learning attitude questionnaire were 3.48 and 0.48 for the control group, and 3.63 and 0.47 for the experimental group, respectively. The t-test result (t ¼ 1.02, p > 0.05) shows that there was no significant difference between the two groups before participating in the web-based problem-solving activity.
After the learning activity, the t-test result (t ¼ 3.77, p < 0.05) showed that the learning attitudes of the students in the experimental group significantly improved after the learning activity in comparison with the control group, as shown in Table 3. Consequently, it can be seen that the online game approach improved not only the students’ learning achievements, but also their attitudes toward the natural science course. Such findings conform to what has been reported by previous studies that situating students in collaborative educational computer games can improve their attitudes toward learning (Chang et al., 2010; Wang & Chen, 2010).
