Design of a Digital Ethnomathematics Module Based on Augmented Reality: A Study on Geometric Concepts Through the Exploration of the Mande Karesemen for Elementary Schools
No full textThis study presents the design of a digital ethnomathematics module using augmented reality (AR) to enhance the learning of geometric concepts for elementary school students, integrating local cultural elements from the Mande Karesemen at Keraton Kesepuhan, Cirebon. Employing the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model, the research focuses on developing an interactive module that aligns with students’ cognitive development and curriculum standards, specifically targeting 4th and 5th-grade students. The module incorporates threedimensional (3D) models of cultural artifacts, enabling students to explore and visualize shapes, symmetry, area, and perimeter in a culturally contextualized manner. The AR feature allows students to engage with the historical and cultural aspects of the Keraton Kesepuhan, experiencing architectural designs that embody geometric concepts. Additional features include AR-based virtual tours, narrated instructions, gamified quizzes, and offline accessibility, fostering a deeper connection between mathematical concepts and cultural heritage. By facilitating active exploration, the module helps bridge the gap between abstract mathematical principles and tangible, real-world examples. This innovative approach addresses challenges in elementary mathematics education by improving student engagement, understanding, and cultural awareness through an immersive and meaningful learning experience, making mathematics more relevant and accessible to students by incorporating their local culture and heritage into the learning process
Elementary Teachers’ Perception of Language Skills: Student Skills and Learning Strategy
No full textLanguage skills are an important aspect in the development of education in elementary schools because this ability influences students’ academic achievement and social abilities. Language skills that elementary school students must master include listening, speaking, reading, and writing skills.Therefore, teachers must understand the extent of language skills each elementary school student possesses. This research aims to explore teachers’ perceptions of the language skills possessed by students in elementary schools, as well as the challenges faced in the teaching process. The research method used is descriptive qualitative, with data collection through interviews. Participants in this research were 15 elementary school teachers in West Bandung. The research results show that the majority of teachers have a positive perception of the importance of language skills in students. However, teachers also expressed challenges in implementing effective learning strategies, such as limited time, lack of appropriate teaching materials, and differences in language abilities among students. This study suggests the need for ongoing training for teachers and the development of teaching materials that better suit students’ needs. In conclusion, teachers’ perceptions of language skills are very important in determining learning success, but further support is still needed in terms of resources and learning methods

No full textBackground: Non-proliferative diabetic retinopathy (NPDR) is a significant complication of long-term diabetes in Sudan. This study aimed to determine the prevalence and risk factors of diabetic retinopathy among Sudanese individuals with type 2 diabetes mellitus who are taking oral antidiabetic medication.
Methods: This cross-sectional, facility-based study recruited 196 individuals with type 2 diabetes at the Jabir Abu Eliz Diabetes Health Center in Khartoum State. Data were collected through a structured questionnaire, which patients filled out after providing informed consent. The data were analyzed using the Statistical Package for the Social Sciences (SPSS). Logistic regression was performed to predict factors associated with diabetic retinopathy.
Results: The mean age of the patients was 50.1 ± 10.7 years. The prevalence of NPDR was 78 (39.8%). Bivariate analysis revealed that age, education level, and residence (Pvalue < 0.05) were significantly associated with diabetic retinopathy. Additional factors that were significantly associated with diabetic retinopathy included the duration of diabetes, the presence of other comorbidities, HbA1c, and fasting blood glucose in 68 (87.2%) individuals (P-value < 0.05).
Conclusion: The study revealed a prevalence of 39.8% for NPDR in this cohort. A longer duration of diabetes and poor control are the primary risk factors for diabetic retinopathy in Sudan. Further research is necessary to determine whether intensifying therapy or administering insulin may reduce the prevalence of retinopathy
