Structured Reading-Supported Activity Sheets: A Strategy for Improving Grade 11 Learners' Performance in Business Mathematics

Abstract

This study examined the effectiveness of activity sheets in Business Mathematics that integrate structured reading support and 21st-century skills to improve learners’ performance and problem-solving abilities. Designed to enhance knowledge construction, collaboration, and real-life problem-solving, the activity sheets were validated using the 21st Century Learning Design (21CLD) rubric, with feedback from evaluators for refinement. A total of 20 Grade 11 learners served as respondents, utilizing a 40-item achievement test and a problem-solving skills scale for pre- and post-intervention data collection. The subsequent statistical analysis revealed that the paired difference scores were non-normally distributed. Consequently, the non-parametric Wilcoxon Signed-Rank Test was employed to maintain analytical rigor and assess improvements in performance. This test showed significant improvements in learners’ achievement (Z = ?2.657, p =.008) and problem-solving skills (Z = ?3.888, p =.001), with a notable shift in performance levels, reducing the number of beginning learners and increasing proficient and basic learners. Evaluators praised the activity sheets’ relevance to real-world business contexts and their promotion of collaboration and creativity, suggesting improvements such as alternative strategy prompts and enhanced data presentation. The findings support the integration of reading strategies into mathematics instruction to foster 21st-century competencies and deeper learning experiences, encouraging teachers to adopt similar approaches.
