Abstract

Mathematics is often considered an abstract subject and difficult for elementary school students to understand, especially flat material. The lack of interesting and contextual learning media makes students less motivated to learn. In fact, mathematics learning can be connected to local culture through an ethnomathematics approach, which can make abstract concepts more meaningful. This research aims to describe the design of digital comic media based on Jejaitan Bali ethnomathematics, determine the feasibility of digital comic media based on Jejaitan Bali ethnomathematics, and determine the effectiveness of digital comic media based on Jejaitan Bali ethnomathematics on flat material. This development research uses the ADDIE development model. The subjects of this research were fourth grade elementary school students with a total of 31 students. The data collection methods used are interviews, observations, questionnaires and tests. The data analysis used is quantitative and qualitative descriptive analysis, as well as inferential statistical analysis. The main results of this research show that digital comic media based on Balinese jejaitan ethnomathematics is effective in increasing understanding of the concept of flat shapes in fourth grade students. The media developed successfully links mathematical concepts with local culture, so that students understand the material more easily through examples that are familiar in their daily lives.  The implications of this research indicate that the integration of local culture into learning media, such as digital comics based on Balinese jejaitan ethnomathematics, can be an effective strategy for increasing understanding of basic mathematics concepts in elementary schools. By utilizing cultural elements that are close to students' lives, learning becomes more contextual, meaningful and interesting, thereby increasing students' motivation and active involvement in the learning process.

Abstract

Although mathematics learning at the Elementary School level has undergone various innovations, many students still have difficulty understanding mathematical concepts. To overcome this problem, a learning media is needed to stimulate students' cognitive activities, such as E-LKPD (Electronic Student Worksheet) based on APOS Theory (Action, Process, Object, Schema), which emphasizes the stages of students' mathematical thinking development. This study aimed to analyze the effectiveness of E-LKPD based on APOS theory (Action, Process, Object, Schema), which is valid, practical, and effective in improving students' adaptive reasoning. The development model used is the ADDIE model. The subjects of this study were 30 fourth-grade students. The trial subjects included lecturers, teachers and students. The data collection methods and instruments used were interviews, observations, questionnaires and tests. Data analysis techniques included quantitative, qualitative and inferential descriptive analysis. The results of this study indicate that E-LKPD media based on APOS theory effectively improves students' adaptive reasoning on mathematical material, picture patterns, and number patterns in fourth-grade students. Based on APOS theory, this study implies that E-LKPD can be an alternative digital learning media that supports meaningful learning and the development of high-level thinking skills from an early age.

Abstract

Student learning outcomes in mathematics, particularly in data presentation, are still relatively low. This is due to the use of conventional teaching methods that are uninteresting and unsuited to students' learning styles, resulting in poor conceptual understanding and low motivation to learn. This study aims to create an ICARE-based animated video medium. This is a research and development (R&D) study using the ADDIE model (Analyze, Design, Develop, Implement, Evaluate). The research subjects include subject matter experts, instructional designers, learning media specialists, and 32 fourth-grade students. Data were collected using Likert scale questionnaires and multiple-choice tests, while the instruments used were questionnaire sheets and test sheets. Data were analyzed using quantitative descriptive statistics and a one-sample t-test. The results of the study indicate that the developed animated video media have excellent quality based on expert evaluations and student trials. In conclusion, the use of animated video media based on the ICARE model in data presentation materials can enhance students' conceptual understanding and learning motivation in fourth-grade elementary school. Implications suggest that the application of this media can serve as an innovative alternative to improve the quality of mathematics education and support more interactive and engaging learning methods for students.
