Abstract

This research aims to develop an augmented reality-based teaching material, namely the AR-Geo module on 3D Geometry material at SMA Negeri 3 Medan. These teaching materials are able to determine the level of validity, practicality, and effectiveness of the AR-Geo module and student responses to learning. This research method used research and development (RD) through the ADDIE model. The subjects of the study involved students of class XII IPS 1 SMAN 3 Medan in the academic year 2023/2024 totaling 36 students. The research instruments employed AR-Geo module assessment sheets by media and material expert lecturers, mathematics teachers, peers, student ability tests and student response questionnaires, as well as student spatial ability tests. The results indicate that the material expert score is 91,53% and the design expert score is 90,53%, classified as very valid. The practicality of the module can be identified from the teacher response questionnaire score of 80,00% classified as practical, and the questionnaire score in the small group trial of 84,26%, field test 84,38% classified as very practical. The effectiveness is shown by 83,33% of students completing the learning outcomes test, and the results of the N-Gain calculation are 17 students experiencing an increase in medium spatial ability and 19 students experiencing an increase in high spatial ability. As a result, the development of augmented reality-based modules for 3D geometry material that has been developed is feasible to use.

Abstract

The unity of teachers with the organization where they work, where the teacher feels that he has an organization and enjoys the conditions of the organization and his work, not only physically but also rationally, emotionally and normatively, so that the teacher feels satisfied and loyal to work in his organization is called teacher engagement. Optimal teacher engagement behavior will have a positive impact on the performance of their work and the madrasah institution. With a sense of love for their work and institution, teachers in carrying out their work work without knowing the time and fully invest themselves and their energy because they are no longer carrying out obligations, but the teaching profession has become a service. in his life. The aim of this research is to find strategies and ways to increase teacher engagement by conducting research on the influence of the variables of self-efficacy, interpersonal communication, organizational support and job satisfaction. This research uses the path analysis method to determine the influence between the variables studied and the SITOREM method for indicator analysis to obtain optimal solutions to increase teacher engagement.

Abstract

Law No. 20 of 2003 on the National Education System mandates inclusive education for children with special needs (ABK) in order to optimize their potential. However, the learning process for kids with mental retardation is hampered by the lack of new learning resources. Thus, a solution is provided by the MathAlfa program with Integrated Video Augmented Reality (AR). In addition to promoting the use of technology in inclusive education, MathAlfa is intended to improve the learning achievement, comprehension, and engagement of children with mental retardation. It is anticipated that features like materials, AR films, and quizzes that rely on visual recognition and direct interaction will be able to give students with mental retardation a more engaging, inclusive, and adaptive learning environment. One technology that has great potential in supporting learning for students with intellectual disabilities is Augmented Reality (AR). AR is a technology that combines virtual objects with real environments in real-time, providing a more immersive interactive experience. By using AR, students can interact directly with learning materials that are visualized in the form of 3D objects, videos, or animations, which can help them understand abstract concepts more concretely and visually.

Abstract

Elementary school children are those who are in their growth period. During their growth period, it is not uncommon for them to be very active and explore new things. While exploring, some of them may fall, slip, get scratched and get wounds on their hands, foreheads or feet. The wounds they get are certainly a valuable experience for them, but do children know how to handle them properly when a child gets injured? Education needs to be given to children so that children at least know what steps or methods to take when they get injured. Based on the results of observations made by the author at SD Negeri 013, Suko Mulyo Village, Sepaku. Education regarding handling open wounds has not been provided optimally. Therefore, the author conducted outreach at the elementary school regarding handling open wounds in children so that children and teachers at the school would pay more attention to how to handle open wounds when children experience falls or other things that cause injuries. The method used is observation and an approach through Role Playing Models. Respondents consisted of 18 grade 4 children at SD Negeri 013. The results achieved showed that children knew what tools were and how to handle open wounds as evidenced by recalling that children were able to mention first aid steps for open wounds in the correct order.

Abstract

This study stems from the low understanding of mathematical concepts among students and aims to examine whether there is a difference in understanding mathematical concepts between students who learn using the cooperative learning model of the articulation type and those who learn using the conventional learning model. The study employs a Quasi-Experimental design with a Pre-test Post-test Control Group Design, involving class VII.1 (experimental class) and VII.2 (control class) at SMP Babussalam Pekanbaru. The results of data analysis using a t-test showed that  (2.98)  (2.01) at a 5% significance level, leading to the acceptance of Hₐ. This demonstrates that the cooperative learning model of the articulation type significantly improves students' understanding of mathematical concepts compared to the conventional learning model, with the average score of the experimental class being higher than that of the control class.

Abstract

The pond-based scientific approach is a scientific approach for students in the aquaculture area, which requires the support of local wisdom-based learning media. With the many scientific approaches that exist, it does not make it difficult for students to raise local wisdom, namely aquaculture, to be used as research in obtaining student learning outcomes. The scientific approach can also provide learning motivation to students so that students are motivated to study harder in lifting student learning outcomes. This study aims to determine the literature review related to the pond-based scientific approach and learning motivation in improving student learning outcomes. The research method chosen is descriptive quantitative by first testing validity, reliability, classical assumptions, partial (t) and simultaneous (f) testing using the help of SPSS Ver,- 2023 software for windows. Data collection was carried out by interview, documentation and questionnaires distributed to respondents who had a population of 200 respondents of SDN 37 Bulu-Bulu, Pangkajene District and the sample was taken by random sampling using 15% of the population totaling 30 respondents of SDN Bulu-bulu students, Pangkajene District, Pangkep Regency. The results of the study partially test or test (t) and simultaneous test (f) pond-based scientific approach has a significant effect on student learning outcomes SDN 37 Bulu-bulu Pangkajene District Pangkep Regency. Then the partial test or test (t) or simultaneous test (f) student learning motivation has a significant effect on the learning outcomes of students of SDN 37 Bulu-bulu, Pangkajene District, Pangkep Regency.
