Research has demonstrated the crucial role of creative metacognition and risk-taking in creativity. However, little empirical research has examined how creative metacognition and risk-taking work on creative performance in educational practice. This paper explored the moderating effects of creative metacognition on the relationships between different types of risk-taking (i.e., propensity for taking a risk, willingness to take a risk) and creative performance (i.e., general creativity, originality, usefulness) in a middle school context. The sample consisted of 350 7th- and 8th-grade students from three middle schools. They completed a survey and a creative performance task. Hierarchical regression analysis revealed that creative metacognition moderated the relationships between willingness to take a risk and both originality and usefulness. The results indicated that creative metacognition reinforces the positive effect of risk-taking on originality and mitigates the negative effect of risk-taking on usefulness. Our findings suggest a potential role for creative metacognition in enhancing curriculum-based creative performance in middle schools. In the end, practical implications, limitations, and future directions are discussed.
