The pedagogy of Social Studies in primary education remains largely traditional, limiting opportunities to develop the creative thinking and collaborative skills required in the twenty-first century. This study aims to examine the effectiveness of the Read, Answer, Discuss, Explain, and Create (RADEC) model integrated with a Mini Gallery project and supported by Canva and CapCut in enhancing students’ creative thinking and collaboration skills in primary Social Studies. This study employed a quasi-experimental method using a nonequivalent control group pretest-posttest design involving 54 fifth-grade students from an elementary school in Purwakarta, Indonesia. Data were collected through creative thinking tests and observations of collaboration skills, and analyzed using descriptive statistics, prerequisite tests, hypothesis testing, N-Gain, and effect size. The results showed that the experimental group achieved greater improvements than the control group in creative thinking (N-Gain = 0.64) and collaboration skills (N-Gain = 0.96). Significant differences were found in creative thinking (p = 0.015) and collaboration skills (p < 0.001). The effect sizes were moderate for creative thinking (Cohen’s d = 0.686) and large for collaboration skills (Glass’s ? = 2.173). The uniqueness of this study lies in integrating the RADEC model, Mini Gallery project, and Canva and CapCut as digital creation and presentation media within primary Social Studies learning. This integrated approach provides a contextual and collaborative learning experience for developing students’ twenty-first-century skills.
