<![CDATA[This study is motivated by the low critical thinking skills of students in science learning, as well as the less than optimal utilization of learning media. This study aims to develop interactive multimedia based on coding which is valid, practical, and effective in improving the critical thinking skills of fifth-grade elementary school students. This type of research is Research and Development (R&D) using the ADDIE model (Analyze, Design, Development, Implementation, Evaluation). The subjects of this study were 4 experts, 3 teachers, and 9 students, as well as all students in grade V totaling 35 students. This study used a pre-experimental design, one-group pretest-posttest. The data collection methods were questionnaires and tests using instruments in the form of questionnaires with rating scales and essay tests. Data were analyzed using quantitative descriptive analysis techniques. The results of the study showed that interactive multimedia based on coding obtained a material expert validity index of 0.97 and a media expert validity index of 0.98 (very high), practicality based on teacher responses reached 98.89% and student responses reached 98.33% (very good), and the correlated t-test showed a significance value (2-tailed) of 0.00 (p < 0.05), confirming the effectiveness of the media in improving students' critical thinking skills. In conclusion, the developed interactive multimedia based on coding was declared valid, practical, and effective in improving the critical thinking skills of fifth grade elementary school students. The implications of this study indicate that learning media based on coding can be an innovative and effective strategy in improving the critical thinking skills of elementary school students.]]>
