Background: Visual arts education has been suggested to influence cognitive and behavioral outcomes, yet its specific effects on critical thinking and behavior regulation remain underexplored. The effect of visual arts education on these domains forms the topic of the present study, which employs a mixed approach research design. Aim: To assess the impact of visual arts education on the improvement of critical thinking and self-regulation in students. Methodology: A quasi-experimental approach was employed with 80 individuals, with 40 in the experimental group Report Phrase receiving education in visual arts and 40 in the control group receiving non-visual arts education. CTST and BRI assessment tools were used to acquire quantitative data about the participants, utilizing the independent and paired sample T-tests. Data collected from participants include interviews, focus group discussions, self-administered, and thematic analysis. A repeated measures ANOVA was used to analyse the data. Result: Statistical findings depicted improvements in the quantitative aspect; critical thinking skills improved from 70.0 to 75.3 with p<0.001 and behavior regulation improved from 65.0 to 69.2 with p<0.001 in the experimental-group in contrast to the control-group. The thematic analysis found striking increases in attention, impulse control, task completion, creativity, collaboration, affect expression, and self-esteem of experimental-group participants. Based on the findings of the Repeated Measures ANOVA, significant enhancements were observed in both domains for critical thinking and behavior regulation with effect size estimates of 0.40 and 0.30, respectively. Conclusion: The development of critical thinking and behavior control in students is greatly impacted by art instruction. Quantitative and qualitative data both support the utility of using visual arts interventions for cognitive and behavioral development and inform practice in art education.
