A recent study investigated whether robot programming offers added benefits over unplugged programming for developing preschoolers’ computational thinking (CT) and executive functions (EFs), given limited comparative evidence in early childhood contexts.
The authors conducted a randomized controlled trial with 198 children aged 5 to 6 from one public kindergarten in China. Children were randomly assigned to a robot programming group using the Matatalab kit (n = 66), an unplugged programming group using paper and pencil based activities (n = 66), or a business as usual control group engaging in conventional kindergarten activities (n = 66). The intervention lasted 12 weeks, with one 60 minute session per week. CT was assessed with TechCheck K (15 items; Cronbach’s alpha = 0.79 in this study), and EFs were measured with the Early Year Toolbox tasks assessing inhibition (Go/No-Go), working memory (Mr. Ant), and cognitive flexibility (Card Sorting). Measures were administered at baseline, week 6, and week 12, and effects were analysed using linear mixed effects models; implementation fidelity was reported as 97 percent adherence.
Results showed that both robot programming and unplugged programming groups outperformed the control group on CT over time, and the robot programming group showed stronger CT gains than the unplugged group by week 12. For EFs, the robot programming group outperformed both the unplugged programming and control groups over time on inhibition, working memory, and cognitive flexibility; within group analyses indicated significant improvements after 12 weeks only in the robot programming group for these EF outcomes. Most children in the robot programming group reported positive perceptions of programmable robots, including ease of use (79%), perceived usefulness (91%), technology anxiety (91%), satisfaction (94%), attitude (82%), and intention to continue use (85%).
The study suggests that while both modalities can support preschoolers’ CT, robot programming may produce more substantial and sustained benefits, particularly for EFs. The authors recommend further research with more diverse samples, longer follow up, mixed quantitative and qualitative evidence, and continued validation of EF measures and programming tools.
