So that from the first school one class was taught for critical thinking skills and the other from the school one was assigned to the control group. The number of subjects was based on Cohen's table with effect size of 0.50 and test power of 0.97, sample size for experimental group 24 and control group of 24 persons. The instruments used in the study were Matson's Social Skills Questionnaire (1983) and Neural Cognitive Skills Questionnaire (2013).
