The Synergy Between 21st-Century Skills and Mathematical Proficiency

The integration of 21st-century skills into mathematics education remains a critical yet underaddressed challenge, particularly in fostering adaptive expertise and addressing persistent gaps in algebraic preparation. This study aimed to investigate the relationship between 21st-century skills (critical thinking, problem-solving, creativity, innovation, communication, cooperation, and digital literacy) and mathematical proficiency in rational exponents and variation, while identifying their interaction effects on student success. A descriptive-correlational method was employed, combining quantitative regression analysis and qualitative data from structured/unstructured assessments. The study involved 172 Grade 9 students across diverse curricular tracks (STE, SPA, SPS, K–12), with 21st-century skills assessed via rubric-based evaluations and mathematical proficiency measured through DepEd-aligned percentage scores. Results revealed a statistically significant positive correlation (β=0.601, p=0.000), rejecting the null hypothesis. The 21st-century skills affecting the mathematical proficiency in variation and rational exponents. The findings underscore the necessity of curriculum reforms prioritizing on enhancing the 21st-century skills instruction to bridge gaps in mathematical proficiency.
