Comparing the Effects of Plugged-In and Unplugged Activities on Computational Thinking Development in Young Children

Children's preschool years are crucial for the development of computational thinking (CT) skills. However, debate continues regarding whether CT should be developed through plugged-in or unplugged activities. This study investigated the similarities and differences between plugged-in and unplugged activities with similar learning content and assessment methods for cultivating computational thinking (CT) in young children. Twenty-four young children (aged 5-6 years) from a kindergarten in Foshan, China, were randomly assigned to either the plugged-in or unplugged group to participate in a five-week study. In the plugged-in group, Dodobot was used in the classroom, while in the unplugged group, unplugged materials such as paper, pencil and tangram puzzles were used. Research results indicate that 1) both plugged-in and unplugged activities significantly improved the young children's CT skills after a short-term educational intervention, but there were no significant differences between the two groups; 2) the extent to which the plugged-in and unplugged activities promoted subdimensions of CT was different, with the plugged-in group demonstrating significant improvements in hardware, algorithm, and modularity and the unplugged group demonstrating significant improvements in terms of representation; 3) the children from both the plugged-in and unplugged groups showed high motivation; And 4) the children in both the plugged-in and unplugged groups showed cooperative behaviors. The frequency of cooperative behavior was more related to materials, and cooperation quality was more related to teacher guidance.
