Creativity and collaboration are fundamental 21st-century skills; however, their attainment in elementary schools remains low due to the dominance of lecture-based teaching methods. This study aimed to improve the creativity and collaboration of fourth-grade students at SDN 1 Kauman through the application of Project Based Learning (PjBL) assisted by Canva on the topic of environmental conservation. This Classroom Action Research (CAR) spiral model, implemented in three cycles,The research subjects comprised 28 fourth-grade students (18 boys, 10 girls) aged 9–10 years in the 2025/2026 academic year, selected through purposive sampling. Data collection instruments included a creativity observation rubric with three indicators (new ideas, flexible thinking, and tangible work) and a collaboration observation rubric with three indicators (care, sharing, and teamwork), complemented by semi-structured interviews, field notes, and documentation. Data were analyzed both quantitatively and qualitatively with source and method triangulation to ensure data trustworthiness. The results demonstrated consistent improvement across cycles: creativity rose from 39.7% (cycle I, Low) to 61.1% (cycle II, Fair) and 81.7% (cycle III, Very Good), while collaboration rose from 44.4% to 68.7% and 90.1% (cycle III, Very Good), both surpassing the success criterion of ≥80% by cycle III. The most substantial gains occurred in flexible thinking (41.7%→94.0%) and teamwork (51.2%→98.8%), whereas the tangible-work and care indicators improved more slowly. These findings confirm that PjBL assisted by Canva, implemented through a graduated sequence of activities, consistently and effectively enhances creativity and collaboration among elementary school students.
