Abstract

Information Technology really supports the teaching and learning process in mathematics learning, but in reality there are still very few teachers who use ICT in learning activities, even though if teachers use ICT in the learning process it can help students and teachers in learning mathematics. This research aims to determine the effect of multimedia mathematics learning assisted by the Geogebra application on students' conceptual understanding of exponential and logarithmic function material. The research method used is Research and Development (R&D), referring to the ADDIE development model. The subject of this research was carried out at SMA Negeri 1 SILIMAKUTA class X-3. The instruments used are student online response questionnaires, teacher online response questionnaires. Based on the results of testing the development of teaching materials assisted by Geogebra in learning exponential and logarithmic functions, from all aspects of statements from student response questionnaires and teacher responses, the average response percentage was 89.7%. Thus, the high percentage of student responses proves that the development of mathematics learning media assisted by Geogebra can increase students' understanding of concepts and can be used effectively and practically as an additional reference for mathematics learning media, especially material on exponential and logarithmic functions. The implication is that if every lesson uses the right media, it will increase students' learning motivation and improve their learning achievement.

Abstract

This study aims to develop interactive learning media based on PowerPoint and Desmos applications for studying curved surface solid geometry. The approach used is Research and Development (R&D), focusing on data collection through questionnaires to measure the effectiveness of the developed media. Three validators were involved in the validation process to ensure the accuracy and validity of the content and instructional media structure. Subsequently, the media was piloted with 10 tenth-grade students from SMA Negeri 1 as part of evaluating its practicality and ease of understanding. The research findings indicate that the interactive PowerPoint-based learning media and Desmos application developed by the researcher meet highly valid criteria. Validation by three independent validators confirms that the content and presentation of the media align with expected standards. Furthermore, student feedback during the pilot study indicates that the media is perceived as practical and easy to comprehend, facilitating the teaching and learning process more effectively. Thus, this development of learning media contributes positively to enhancing the quality of learning curved surface solid geometry through the integration of relevant and innovative technologies.

Abstract

This study aims to develop an Augmented Reality (AR)-based learning media utilizing GeoGebra 3D to teach the Ceva's Theorem in a triangular prism, with the goal of enhancing students' conceptual understanding and interest in learning mathematics. The research employs a Research and Development (R&D) approach using the ADDIE development model, which includes five stages: Analysis, Design, Development, Implementation, and Evaluation. Data collection techniques involved media validation sheets, content validation sheets, practicality questionnaires, concept understanding tests, and student interest questionnaires. The validation results indicated that the developed media was highly valid, with an average score of 4.62 for technological design and 4.54 for content. The practicality of the media was also rated very practical by both teachers (4.7) and students (4.58). The effectiveness test revealed a significant improvement in concept understanding, with a gain value of 0.59 (moderate category), as well as an increase in student interest, reflected by an average score of 4.32 (high category). These findings indicate that the AR-based learning media using GeoGebra 3D is not only valid and practical but also effective in improving students' understanding and interest in complex spatial geometry topics. This study contributes to the development of interactive, contextual, and digital learning innovations that align with the demands of 21st-century education.
