4.4. Analysis strategy
In the present study, the Statistical Package for Social Science (SPSS 17.0) was used for data analysis, which included computation of
univariate and multivariate General Linear Model (GLM), paired-samples t-tests, and Pearson correlations. Multivariate GLM was employed
to analyze if groups’ problem-solving performance and cognitive load differed significantly from each other. Univariate GLM was used to
analyze if group learning performance differed significantly from each other due to the interaction effect of the diverse learning abilities of
the students. Paired-samples t-tests were applied to analyze if the learning attitudes of students toward social science differed significantly
before and after experiments. Pearson correlation was applied to investigate if the correlation between learning performance and learning
attitudes of the experimental group students showed a positive inclination. To evaluate the treatment effects, the effect size was calculated
for the instrument. The alpha was established a priori at the 0.05 level, as suggested in the literature.
