Abstract

Learning media plays a very important role in teaching Mathematics at the elementary school level because it helps students transform abstract concepts into more concrete and understandable forms. However, the low understanding of Grade III students regarding long division material is caused by the limited availability of engaging and contextual learning media. This study aims to analyze the effectiveness of the interactive multimedia “Porogapit Math” based on bar diagrams, which is feasible and effective for use in Mathematics learning. The development model employed in this study was the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The research subjects consisted of 28 Grade III students. Data collection methods and instruments included questionnaires to test the validity and practicality of the multimedia, as well as essay tests to measure its effectiveness. Data analysis techniques were conducted using quantitative descriptive, qualitative, and inferential methods. Based on the results of the t-test, the obtained t-value was 2.287, while the t-table value with df = (n – 1) = 27 at a 5% significance level was 2.052, indicating that tvalue > ttable, meaning that H₀ was rejected. Therefore, it can be concluded that the interactive multimedia “Porogapit Math” based on bar diagrams is effective for teaching division material in Grade III. The implication of this study is that “Porogapit Math” can serve as an innovative learning alternative that facilitates students’ understanding of long division concepts in a visual, interactive, and enjoyable way.

Abstract

The problem addressed in this study is the lack of instructional media that can enhance students' interest and understanding of fraction operations through an approach that is relevant to everyday life. The aim of this study is to develop contextual-based animated video media for teaching mathematics, specifically the topic of fraction operations, in fifth-grade elementary school. This research employs the ADDIE development model, with data collected through questionnaires, objective tests (multiple-choice), and analyzed using descriptive quantitative and inferential statistical techniques. The research subjects included one media expert, one subject matter expert, one instructional design expert, and fifth-grade elementary school students consisting of three students for individual trials and nine students for small group trials. The results showed that the animated video media design in digital format covered competencies, content, example problems, and developer profiles, with an expert validation score of 92.5% (categorized as excellent). The product feasibility tests indicated that the animated video media is suitable for use, with validation results from subject matter experts (92%), instructional design experts (95%), media experts (94%), individual trials (92.5%), and small group trials (93.05%), all categorized as excellent. The effectiveness test using a t-test analysis showed that the students’ post-test average score (91.87) exceeded the BSKAP standard score (86), with the t-test result showing t-count = 3.73 > t-table = 1.75 at a 5% significance level (α = 0.05). Therefore, it can be concluded that the contextual-based animated video media is appropriate and effective for use in teaching fraction operations in fifth-grade elementary school.
