This can be seen in the results of the paired sample t test, the results of the test conducted in the experimental group. The value obtained is, |-7,494| > 2.093 t table and significance value (2-tailed), in table. The significance value (2-tailed) was 0.001 (p <0.05). And the value obtained in the control group, namely |-7,159| > 21.19 t table, significance value (2 tailed) in table. As well as the acquisition of critical thinking ability questionnaires in the control and experimental groups, namely, |62,29| > 2.028 t table and significance value (2 tailed) in the table.
