Hardianto — 2024-12-11

This study aims to determine procedures for developing digital modules in Bugis cultural context to strengthen character education and improve numeracy literacy skills that are feasible to use. The type of research used is research and development (R&D). The population of this study were fifth-grade students of SD Negeri 296 Lapaukke. The results of this study indicate that the Digital module developed using the ADDIE model through 5 stages, namely, analysis, design, development, implementation, and evaluation. Based on the results of the study, it was found that: (1) The Bugis cultural context digital module is feasible to use in improving students' numeracy literacy. This is evidenced by the calculation results of media experts by 95% (very valid) and material experts by 100% (very valid) obtained a percentage of 97.5% (very valid). The recapitulation results of the student response questionnaire are 100% (very practical). From the recapitulation of student tests, the average score is 78.4% (effective). (2) The development of Bugis cultural context digital modules on strengthening character education and improving students' numeracy literacy skills is very effective. This is evident from the numeracy literacy test results of 21 students who completed or 95% of the total number of students and there was only one student who did not complete or 5% of the total number of students. The conclusion is that the Bugis cultural context digital module is effective in strengthening character education and improving students' numeracy literacy skills.

The INCREASING STUDENTS' CONCEPT UNDERSTANDING CAPABILITY IN STATISTICS MATERIAL THROUGH THE DISCOVERY LEARNING MODEL

Meitia Putri Pratiwi — 2024-12-11

This research aims to determine the effect of the discovery learning model on high school students' mathematical abilities. This type of research is classroom action research, which aims to increase educators' professionalism in improving student learning outcomes. This research was carried out at senior high school Yumik Banjaran. The subjects in this research involved students in class XII IPA 1 for the 2023/2024 academic year with 36 students. The research instrument used was a description test during the pre-test and post-test. The learning material provided is data-centering statistical material. The tests carried out are divided into two parts, namely test cycles I and II (after giving the action). The procedures in this research consist of: (1) planning, (2) implementation of actions, (3) observation, and evaluation, and (4) reflection. The results of this research show that in cycle I the researcher was not optimal in providing understanding to students so there were still many students who did not understand the statistical material of data concentration, however in cycle II the researcher improved the learning method by paying more attention to the systematics in the discovery learning model so that after cycle II is completed, students' mathematical understanding abilities can increase. Based on the performance indicators, it is concluded that students' mastery of mathematical understanding in the data-centering statistics material for class XII IPA 1 students at senior high school Yumik Banjaran can be improved through the discovery learning model.

DEVELOPMENT OF MATHEMATICS LEARNING MODULES BASED ON CREATIVE PROBLEM-SOLVING ON TRIGONOMETRY MATERIAL

Fitriani Nur — 2024-12-11

The development of effective and innovative mathematics learning modules is an important effort to improve the quality of the learning process, especially in materials that require concept understanding and creative thinking skills, such as trigonometry. One model that can be used to achieve this goal is creative problem solving (CPS), which invites students to find innovative and effective solutions to complex mathematical problems. This study aims to develop a math learning module based on creative problem-solving on trigonometry material that is valid, practical, and effective. The module development was conducted using the ADDIE model which consists of five stages, namely analysis, design, development, implementation, and evaluation. The test subjects involved students of SMAN 21 Gowa. The research instruments were module validation sheets, educator and learner response questionnaires, observation sheets, and learner learning outcomes tests. The research data analysis focused on analyzing the validity, practicality, and effectiveness of the creative problem-solving-based mathematics learning module on trigonometry material. The results showed that the creative problem-solving-based math learning module on trigonometry material had met the criteria of validity, practicality, and effectiveness. Thus, this learning module is suitable for use in the implementation of mathematics learning, especially in trigonometry material.

FUNETHNOMATH: DEVELOPMENT OF VIRTUAL REALITY TOUR WEB LEARNING MEDIA WITH AN ETHNOMATHEMATICS

Nur Hasanah — 2024-12-11

This research aims to develop a funethnomath learning media based on a virtual reality tour in the form of a website using a valid ethnomathematics approach. This research is a development type or RnD with the ADDIE model, consisting of the stages of analysis, design, development, implementation, and evaluation, which is limited to the development stage. Data collection techniques include interviews, observations, documentation, and questionnaires. The validation questionnaire is given to material and media experts. The research instrument uses a validation questionnaire for media and material experts. The media expert validation questionnaire has several assessment aspects, including appearance, software engineering, and visual communication. The material expert validation questionnaire has several assessment aspects, including material design and language. The data analysis of the questionnaire is determined according to the media validity assessment guidelines. The results of this study show that the developed media has valid criteria with a final score of 3.015 in the media expert validation with assessment aspects of appearance, software engineering, and visual communication, and a final score of 3.0625 in the material expert validation with assessment aspects of material design and final value.

EXPLORATION OF ETHNOMATHEMATICS IN THE ANRI (NATIONAL ARCHIVES OF THE REPUBLIC INDONESIA) BUILDING WEST JAKARTA

Muhammad adrian — 2024-12-12

Mathematics and culture have a strong relationship in life. In Indonesia, culture is different from local wisdom, and the culture of certain community groups or tribes that support mathematical activities is called ethnomathematics. One example is cultural heritage buildings, such as the ANRI (National Archives of the Republic of Indonesia) building which was founded in 1750 in DKI Jakarta Province, precisely on Jalan Gajah Mada, West Jakarta. The purpose of the research that we use, which is exploratory with this ethnographic method, is to find and categorize the mathematical concepts contained in the ANRI building which is one of the sources of learning mathematics and efforts to develop ethnomathematics as a basis for mathematics learning. This study focuses on understanding the informal mathematical knowledge acquired by local people from their environment and culture, especially those related to cultural heritage sites, which are referred to as ethnomathematics. The study findings show that the National Archives Building is a significant cultural heritage site with historical and architectural significance. The architectural features of the building, such as the rectangular and trapezoidal shapes of the main structure and roof, reflect various geometric concepts. Overall, this research emphasizes the importance of preserving cultural heritage and documents in the National Archives to retain the historical knowledge contained within. Ethnomathematics provides a valuable framework to explore and appreciate mathematical concepts embedded in cultural artifacts, promoting a deeper understanding of mathematics through real-world activities and cultural practices.
