This study examined the effects of STEAM-based activities on preschoolers' problem-solving skills using an explanatory sequential mixed-methods design. In the quantitative phase, a pretest-posttest control-group quasi-experimental design was implemented with 97 children attending a public preschool. The experimental group participated in 32 STEAM activities over eight weeks, while the control group continued the standard curriculum. Quantitative data were collected using the Problem-Solving Skills Scale, and in the qualitative phase, semi-structured interviews were conducted with children, parents, and teachers. Findings revealed that children in the experimental group demonstrated significantly greater improvements in problem-solving skills compared to the control group. STEAM activities were found to support cognitive flexibility, creativity, social interaction, emotion regulation, and autonomy. Overall, the study suggests that STEAM provides a functional pedagogical framework for fostering problem-solving and 21st-century skills in early childhood and recommends its systematic integration into preschool programs.
