Evaluation of Learning Kit an Intervention Learning material to Enhance Students' Mastery in Mathematics in the Modern World

Abstract

Mathematics continues to be a challenging subject for many first-year college students, often affecting their academic performance, engagement, and overall learning outcomes. The development of high-quality instructional materials is therefore essential in facilitating meaningful learning experiences and improving students’ mathematical competence. This study aimed to develop and evaluate a learning kit for the course Mathematics in the Modern World and determine its acceptability and effectiveness in enhancing students’ mathematical performance. The study employed a purely quantitative research design using a developmental-evaluative approach. The learning kit was developed based on the course learning competencies and was subjected to expert validation to assess its format, content, clarity, and usefulness. Subsequently, field testing was conducted among 39 first-year college students using a one-group pretest–posttest design. Data were analyzed using weighted mean, analysis of variance, and paired-samples t-test.
The findings revealed that the developed learning kit obtained a grand mean rating of 3.87, interpreted as Highly Acceptable, indicating that the material met established standards for instructional quality and usability. Results further showed a statistically significant difference in the ratings provided by experts across the validation components, suggesting varying levels of evaluation regarding the format, content, clarity, and usefulness of the learning kit. Moreover, the effectiveness assessment demonstrated a statistically significant improvement in students’ mathematical performance following exposure to the intervention with a computed t of 11.92 and a p < .001, indicating that the learning kit contributed positively to student learning outcomes. These findings affirm the instructional value and effectiveness of the developed material as a supplementary learning resource. The study concludes that the learning kit can serve as a viable instructional tool for enhancing mathematics instruction and improving student achievement in higher education.
