Collaboration skills and learning outcomes are important aspects that support students’ success in science learning. However, these competencies are often not optimally developed through conventional learning approaches. This study aimed to examine the level, improvement, and significance of the increase in collaboration skills and learning outcomes of Grade VIII students at SMPN 27 Makassar through the implementation of the Student Teams Achievement Division (STAD) model assisted by Sketchfab. The study employed a pre-experimental method with a one-group pretest-posttest design. The sample consisted of 34 students from Class VIII.10 selected through purposive sampling. Data were collected using a collaboration skills questionnaire and a learning outcomes test and were analyzed using descriptive and inferential statistics. The results showed that the average collaboration skills score increased from 61.06 to 73.91, while the average learning outcomes score increased from 8.26 to 11.97. The N-Gain values indicated a moderate improvement in collaboration skills (0.32) and learning outcomes (0.55). In addition, the t-test results revealed a statistically significant increase in both variables (p < 0.05). Therefore, the STAD model assisted by Sketchfab can effectively enhance students’ collaboration skills and learning outcomes in science learning.
