Educational robotics or unplugged coding activities in kindergartens?: Comparison of the effects on pre-school children's computational thinking and executive function skills

This study compares the effects of coding education with educational robot and unplugged coding activities on pre-school students' computational thinking and executive function skills. This study used a pre-test and post-test comparison group quasi-experimental design. The study was conducted in a public kindergarten with 48 pre-school students (24 educational robot- BeeBot® group and 24-unplugged coding group) aged 5-6. The TechCheck-K test was used to measure computational thinking skills, and Executive Functions Battery-Computerized Touch was used to measure executive function skills. The process started with pre-test applications and ended with post-tests after four weeks (16 different sessions) of the implementation in both groups. The study found a statistically significant difference between the computational thinking pre-test and post-test scores of pre-school students in both groups in favor of the post-test. It was determined that there was a statistically significant difference in favor of the educational robot group between the post-test scores of computational thinking skills. In addition, when the findings regarding executive functions were evaluated, there was a statistically significant difference between the pre-test and post-test scores of total executive function in favor of the post-test in both groups. However, it was observed that there was no statistically significant difference between the post-test scores of both groups in terms of total executive function skills scores. In addition, when the post-test scores of pre-school students in two groups were evaluated, it was determined that there was no significant difference in computational thinking and executive function skills according to gender. Consequently, it was determined that coding education with an educational robot was more effective for gaining computational thinking skills than unplugged coding activities for pre-school students. However, it was observed that there was no difference between the two groups in terms of the development of executive function skills in pre-school education.
