The Impact of STEM Instruction on 21st-Century Skills among Elementary School Students: A Systematic Literature

Abstract

The rapid demands of a globalized, knowledge-based economy require elementary education to move beyond memorization and toward cultivating critical thinking, creativity, collaboration, and communication, collectively known as the 4Cs. Science, Technology, Engineering, and Mathematics (STEM) instruction has been proposed as a promising vehicle for developing these competencies, yet evidence on its specific effects for elementary students remains fragmented. This study employed a qualitative systematic literature review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol to map recent research patterns, identify underexplored gaps, and generate practical recommendations regarding STEM instruction's impact on elementary students' 21st-century skills. Following multistage screening across the Scopus and Google Scholar databases, 22 empirical articles published between 2021 and 2026 in indexed journals met the inclusion criteria and were analyzed using content analysis. Results show that STEM instruction was consistently associated with positive gains across all four skill dimensions, with critical thinking (18 articles) and creativity (11 articles) most frequently documented, while collaboration (5 articles) and communication (7 articles) remained comparatively underexamined; publication activity peaked in 2024 before declining thereafter. These findings confirm that STEM instruction offers elementary education a viable pathway for cultivating 21st-century competencies while revealing a persistent evidence gap in collaboration and communication outcomes. The study contributes a dimension-specific, elementary-focused synthesis and recommends that future research adopt longer-term, mixed-methods designs to address this imbalance.
