Unplugged Activity To Improve Students' Computational Thinking Skills Second Grade Elementary School

Abstract

This study aims to describe and analyze the application of unplugged activity to improve the computational thinking skills of second-grade elementary school students in a real-world setting with limited access. This is necessary because these skills will be needed in the future, and in Indonesia, many areas still do not fully support information and communication technology. The research design used was a pre-experimental one-group pretest-posttest. The research instrument was a computational thinking skills test covering indicators of decomposition, pattern recognition, abstraction, and algorithms. The results showed a significant difference between the pretest and posttest scores, indicating that unplugged activity was able to improve students' computational thinking skills. Although the gain score was moderate and interpreted as quite effective, this activity was able to motivate and engage students in their learning, making the class not only active but also interactive.
