<![CDATA[ABSTRACT The low level of communication skills among fourth-grade students in Science and Social Studies (IPAS) remains a significant challenge in the learning process. This condition is reflected in students' lack of confidence in expressing opinions, asking questions, and responding to their peers' ideas, which is influenced by the predominance of conventional teaching methods and the limited use of instructional media. This study focuses on developing Colored Paper as an instructional medium that is both feasible and effective in improving the communication skills of fourth-grade students in IPAS. The research employed the Research and Development (R&D) method using the ADDIE model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The feasibility of the product was assessed through validation by subject matter experts, language experts, and media experts, while its effectiveness was evaluated based on teacher and student responses, as well as comparisons of pre-test and post-test results using N-Gain analysis. The findings indicate that the Colored Paper instructional media achieved an overall feasibility score of 88.33%, categorized as highly feasible, based on evaluations from subject matter experts (90%), language experts (88%), and media experts (86%). Student responses reached 97.2%, while teacher responses were 88%, both of which were categorized as very good. The effectiveness of the instructional media was demonstrated by an increase in the students' average communication skills score from 12.64 on the pre-test to 23.72 on the post-test, with an N-Gain score of 0.902 (90.2%), which falls into the high category. Therefore, the Colored Paper instructional media is considered highly feasible and effective in improving the communication skills of fourth-grade students at SDN Lawanggintung 2 Bogor in the IPAS subject.
