This study was conducted in response to low student learning outcomes on the topic of the Social Impact of Informatics, which was attributed to the dominance of lecture-based teaching methods that limited student independence and engagement. The research aimed to evaluate the effectiveness of the Self-Directed Learning (SDL) model in enhancing the learning outcomes of seventh-grade students at SMP Negeri 5 Samarinda. Using a pre-experimental one-group pretest-posttest design, the study involved 24 students. Data were collected through pretest and posttest assessments, observation sheets, and student response questionnaires. The results showed a notable improvement in learning outcomes, with the average pretest score of 70 increasing to 89.17 in the posttest. N-Gain analysis produced a score of 0.63, indicating a moderately effective learning gain. In addition, student responses to the SDL model were highly positive, with an average questionnaire score of 81.29%, demonstrating strong acceptance and enthusiasm for independent learning approaches.
