Abstract
The purpose of this study is to evaluate the efficacy, validity, and practicality of instructional materials designed with the Contextual Teaching and Learning (CTL) approach to improve students' ability to solve mathematical problems. The results of a study done at SMP IT Bina Insan Batang Kuis with eighth-grade students in the 2023–2024 school year show that: 1) The materials are valid; the average validation scores for lesson plans, teaching materials, and student worksheets are 4.59, 4.71, and 4.74. 2) In trial II, practicality scores increased to 4.24 (high) from 3.03 (medium) in trial I. 3) 88.5% of students finished assignments, while success rates for learning objectives ranged from 76.22% to 92.15%, demonstrating effectiveness. Student opinion was positive, averaging 90.2%. 4) There was a noticeable improvement in reasoning abilities; trial II showed an average normalized gain of 0.471, suggesting medium progress.
