Abstract

Mastery of Computational Thinking (CT) has become one of the core skill requirements for students in the digital era, thus demanding innovation in learning media. This study aims to analyze the effectiveness of using the interactive learning media Code.org on improving the CT skills within the STEM learning context of students at a high school in Bekasi City. The research method used is quasi-experimental with a non-equivalent control group design. The instruments used included pre-test and post-test questions based on the Bebras Challenge, as well as student worksheets (LKPD) and a CT assessment rubric. Data was collected through the Bebras Challenge-based test instrument, administered as a pre-test and post-test. Data analysis was performed using descriptive statistics, the non-parametric Mann-Whitney U test, and simple linear regression analysis. The results showed that there was a very significant difference in CT skills (p < 0,001) between the experimental group (mean post-test score of 94,00) and the control group (48,40)- students^ initial ability did not significantly contribute (R Square = 0,010) to their final ability in the experimental group- and there was a significant difference in improvement (N-Gain) (p < 0,001) favoring the experimental group. The implication of this research is that the interactive learning media Code.org is a highly effective media that functions as an ^equalizer^ in developing students^ CT skills, and it is highly recommended for broader integration into the STEM curriculum to prepare students for the challenges of the 21st century
