Pengembangan Media Komik Digital Webtoon Berbantuan Procreate untuk Pembelajaran Barisan dan Deret Aritmatika

Abstract

This research addresses the persistent challenges in mathematics education, particularly the low learning interest and conceptual difficulties experienced by high school students in understanding arithmetic sequences and series. Conventional textbooks, dominated by text and lacking visual appeal, often lead students to memorize formulas without grasping underlying concepts. To overcome these obstacles, this study aims to develop and evaluate the effectiveness of a digital comic-based learning medium utilizing the Webtoon platform, designed with the Procreate application, as an alternative for teaching arithmetic sequences and series to tenth-grade vocational students. Employing the Research and Development approach with the ADDIE model, the research involved needs analysis, instructional material design, comic production, expert validation, and product implementation. The developed digital comic was validated by subject matter experts and media experts, and its effectiveness was tested through pretest and posttest assessments as well as student response questionnaires. The results indicate that the digital comic is highly valid, with expert validation scores exceeding 85% and student responses averaging above 82% in two trial phases. The use of the comic significantly improved students’ understanding, as reflected by a notable increase in posttest scores and a large effect size. These findings demonstrate that integrating digital comics via the Webtoon platform, supported by professional design tools, can enhance conceptual comprehension, motivation, and engagement in mathematics learning. The study recommends broader application of this innovative medium to other mathematical topics and educational contexts to support meaningful learning in the digital era.
