This study aims to determine the effect of the STEM-based learning model on collaboration skills and determine the effective contribution of the STEM-based learning model to collaboration skills in the chemistry subject of buffer solution material. This study uses a quantitative quasi-experimental study with a posttest only with control group design. The population used was all students of class XI IPA SMAN 2 Muara Beliti. The sample taken was done by random sampling with a total of 130 students. The study was conducted with 4 classes, namely 2 experimental classes and 2 control classes with different treatments. The treatment of the experimental class was the STEM-based learning model while the control class used the discovery learning model. The results of the study showed that there was a significant influence of the STEM-based learning model on collaboration skills and provided an effective contribution of 9%, including in the small category. © 2025, Ayse Sahin Ozturk.
