After the experiment, the students’ pre-test scores were regarded as the covariance of ANCOVA to exclude the effects of the pre-test on the students’ learning achievement. Table 8 shows the ANCOVA result. The adjusted means of experimental group A, experimental group B, and the control group were 92.88, 87.41, and 86.80, respectively. The variance F = 4.71 (p.05) indicated the existence of significant differences between the post-test scores of the three groups.
