The purpose of this research is to improve collaboration skills in the topic of measurement through the PBL model. Indicators of collaboration skills include active participation, productive engagement, adaptability, willingness to compromise, responsibility, and mutual respect. This research took place with Grade X learners at Public High School 61 in Jakarta, Indonesia, involving 36 learners. The data were obtained using assessments, conversations, and monitoring. This research utilized the mixed method: the method of classroom action research, following the model proposed by Kemmis and McTaggart, the process involved two cycles, with each cycle including four phases: planning, implementation, observation, and reflection and quantitative research method following hypothesis test. The research was carried out in two cycles. In Cycle I, 3 learners were unable to collaborate, 5 were quite capable, 16 were capable, and 12 showed great capability. In Cycle II, 2 learners were incapable, 4 were quite capable, 14 were capable, and 16 were very capable of collaborating. The hypothesis was accepted as the z-count exceeded the z-table, indicating that the PBL model significantly improved learners' collaboration skills in the measurement topic. The N-gain value was classified as average. © Published under licence by IOP Publishing Ltd.
