Abstract

This study aims to design and develop GeoGebra-assisted E-LKPD learning media for trigonometry topics —tangent, cotangent, and reciprocal identities —to foster 11th-grade students' conceptual understanding. This study employed a Research and Development (R&D) approach using the ADDIE model. The research subjects consisted of  11th-grade students at SMAN 1 Batu. The data analysis techniques used in this study include validity, practicality, and effectiveness analysis. The analysis results indicate that this media is valid, with an average validity score of 3.85 and a material validity score of 3. . The practicality of this media is considered practical based on the student response questionnaire, which yielded an average score of . The effectiveness analysis of this media was based on students' essays on trigonometry material. A total of  of students achieved scores above , thus meeting the effectiveness criteria. Therefore, it can be concluded that the GeoGebra-assisted E-LKPD developed is valid, practical, and effective, making it suitable as a mathematics learning medium to enhance students' conceptual understanding of trigonometry.Keywords: E-LKPD, GeoGebra, Trigonometry

Abstract

This study aims to describe the response of students in class XI to the application of innovative methods and media in learning mathematics in teaching assistance activities at SMA Negeri 1 Batu. The background of this study is the low motivation of students to learn caused by the lack of variety in learning methods and media. The approach used in this descriptive research is a qualitative, with a subject of 36 students (13 male students and 23 female students) in class XI. Data were collected through validated questionnaires and structured interviews. The results of the analysis showed that students gave a positive response, with a score of , to the application of the discovery learning model, independent learning, the use of student worksheets, and interactive media such as Quizizz and snakes and ladders games. These innovations encourage students to be more active, motivated, and assisted in understanding mathematical concepts. Overall, the findings of this study indicate that the application of method and media innovations in teaching assistance activities can increase student involvement and understanding in learning mathematics in a more meaningful and enjoyable way.
