Effect of Using Scratch Website-Based Learning Media on Cognitive Science Learning Outcomes of Middle School Students

This research aims to examine the impact of using Scratch-based website learning tools on the cognitive performance of junior high school students. The study focused on ecology and biodiversity topics in the seventh grade at a junior high school in Sidoarjo district. Two classes were chosen using random sampling; the experimental group utilized the Scratch website, while the control group employed PowerPoint. Data was gathered through pre-test and post-test evaluations, consisting of 20 questions that assessed cognitive skills. The T-test (Independent sample T-Test) results, with a significance level of 0.039, revealed a significant effect on cognitive performance. Although both groups achieved medium-level N-Gain scores, the experimental group scored higher (0.56) than the control group (0.41). Thus, it can be inferred that incorporating the Scratch website into science lessons positively influences the cognitive outcomes of junior high school students.
