PENGEMBANGAN E-MODUL MATERI GEOMETRI MENGGUNAKAN FLIP PDF CORPORATE EDITION BERBANTU APLIKASI GEOGEBRA

Abstract

Good learning takes place when the teacher has media that is able to facilitate the learning process and with good learning media too, especially in mathematics. However, the application of learning using learning media has not been fully implemented by teachers, while students need the help of learning media to make the learning process more varied. Therefore, this development research has the intent and purpose of producing a product that can help teachers and students during the course of the learning process, especially in geometry transformation material. In this research, the development model used is the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). This research was conducted at SMP Negeri 14 Tambun Selatan with 31 class IX students as subjects. Data collection techniques were carried out by interviewing mathematics teachers and students, observing, and filling out questionnaires. The validation process to determine the validity of the module was carried out by 2 media experts and 2 material experts with an overall assessment result of 0.73 which was included in the feasible category. Meanwhile, according to student responses obtained through filling out the student response questionnaire, it is included in the good category with an overall rating of 0.76. According to the students, the developed e-module makes it easier for students to learn, especially in solving geometric transformation problems, both easy and difficult, using the help of the GeoGebra application program.
