Abstract

Designed to boost students' mathematical problem-solving capabilities, this Canva-assisted learning media incorporates the Problem-Based Learning model. Adopting a Research and Development (R&D) approach guided by the ADDIE framework, the study involved students from a junior high school in West Bandung Regency, comprising 10 participants in a limited trial, 39 in an expanded trial, and 28 divided across experimental and control groups. Data were gathered through validation sheets, interviews, observations, and response questionnaires, then processed using both descriptive and inferential statistics. This analytical process aimed to map out the levels of validity, practicality, and N-gain scores. Empirical findings confirmed that the product achieved a "Very Valid" rating, securing feasibility scores of 82% from subject matter experts and 86% from media experts. Regarding practicality, the media earned 90% ("Very Practical") during the limited trial and 78% ("Practical") in the field trial. Based on the N-gain improvement observed in the experimental class, the media proved both effective and dependable as a supporting tool for school mathematics.
