Abstract

Mathematical literacy skills are an essential competency of the 21st century that demands innovation in digital teaching materials. Based on the needs analysis in the field, the use of interactive, self-contained web-based learning media still requires variations and has not explicitly integrated local cultural elements in the Data Centrality Measurement material. This study aims to produce a digital learning media prototype in the form of a flipbook e-module based on Deli Malay ethnomathematics assisted by the Heyzine platform integrated with the Discovery Learning flow, and to test the theoretical feasibility of the product. This type of research is a research and development (R&D) using the 4D model. In accordance with the limitations of the initial feasibility objectives, the development procedure is limited to the Develop stage in the theoretical validity testing phase by experts. Data collection techniques are carried out through documentation studies, structured interviews with teachers, and distribution of Likert scale assessment questionnaire instruments to experts. The assessment data are then analyzed quantitatively using the Aiken's V agreement index formula. The results of the development stage research indicate that the accumulated average content validity index of all learning device instruments is 0.92 with the criteria of Very Valid. In detail, the validity values were obtained from the Teaching Module instrument (0.88), LKPD (0.90), material aspects (0.91), flipbook media (0.94), cultural context (0.92), and the mathematical literacy ability test instrument which achieved the highest coefficient of 0.96. The conclusion of the study confirms that this ethnomathematics-based flipbook e-module product is declared valid, theoretically feasible, and recommended as a variation of independent teaching materials to support the achievement of 21st-century competency mathematics learning.

Abstract

This research aims to develop a mathematics learning medium in the form of an Indonesian culture-based e-comic integrated with the educational values ​​of Imam Syafi'i on the topic of Two-Variable Linear Equation Systems (SPLDV) to improve the mathematical problem-solving skills of students at SMP IT Al Maidani. The urgency of this research is based on the low mathematical problem-solving abilities of junior high school students, as well as the lack of contextual, engaging, and Islamic character-infused learning media. The development model used was the 4D model (Define, Design, Develop, Disseminate). The research subjects consisted of 30 students in the first trial and 32 students in the second trial. Validation was conducted by media experts, material experts, religious experts, and cultural experts. The validation results indicated that the developed learning medium was valid with an average score of 4.3 (media experts), 4.2 (material experts), 4.4 (religious experts), and 4.5 (cultural experts). The first trial resulted in an increase in the average score from 76.9 (pretest) to 83.73 (posttest), with an N-Gain of 0.32 (moderate category). Based on the reflection results of the first trial, revisions were made, including improvements to the interface, the addition of sample verification questions, and additional contextual exercises. After revisions, the second trial showed a significant increase, with an average score from 77.4 to 94.25 and an N-Gain of 0.78 (high category). A total of 87.5% of students achieved classical learning completion. The results of the study demonstrate that the developed e-comic media is valid, practical, and effective in improving students' mathematical problem-solving skills and instilling Islamic character values ​​aligned with the educational values ​​of Imam Syafi'i.
