Collaboration skills are one of the six life skills that are important to have in the 21st century,
enabling students to work together, exchange ideas, and respect other people's opinions. This research aims to
improve collaboration skills through Project-Based Learning (PjBL) on environmental change material. The
research method used was a quasi-experiment with a nonequivalent pretest-posttest control-group design. The
sample for this research is high school students who are studying Environmental Change material. Collaboration
skills questionnaires and observations of learning implementation were used as research instruments. The data
analysis used was the Independent Sample T-Test and the N-Gain test. The results of the Independent Sample TTest show that the average posttest score for the control and experimental classes is significantly different by
0.000. The collaboration skills of experimental class students obtained a mean of 86.39 in the very good
category, and the N-Gain test result was 0.465 in the moderate category. This increase is supported by the
results of learning implementation, with an average score of 89.89% in the very good category. This research
implies that it can provide practical guidance for teachers interested in integrating PjBL into learning.
