Abstract

This research is motivated by the low ability of SMPN 1 IV Koto Aur Malintang students to understand mathematical concepts. These students struggle to solve practical exercises that deviate from the examples provided by the teacher and their low active engagement during learning. This affects the students' low learning performance and does not meet the KKTP defined by the school. This study aims to determine the effect of the Project-Based Learning (PjBL) model supported by the Geogebra class on the understanding of mathematical concepts of 8th grade students of SMPN 1 IV Koto Aur Malintang. This study uses a true post-test experimental design with a single control group. The research sample consists of Grade VIII.1 as the control group and Grade VIII.2 as the experimental class. The instrument used in this study is a post-test in the form of essay questions with a reliability of 0.895. The post-test data analysis shows that the data from the experimental class are not normally distributed. Therefore, the Mann-Whitney test was continued using Minitab version 19, with a p-value of 0.145 at a significance level of . Since the p-value > , is accepted and , is rejected. From the results of this study, it can be concluded that students’ understanding of mathematical concepts when applying the project-based learning model of Geogebra Classroom is not better than their understanding of mathematical concepts when applying the conventional learning model in class VIII SMPN 1 IV Koto Aur Malintang.

Abstract

The purpose of this research is to produce an Android-based e-Module using Sigil software that is valid and practical for Class VIIA Data Presentation at SMP N 24 Padang that is valid and practical so that it can be used as a source of learning mathematics, especially data presentation material. The type of research used is development research. This research uses the Plomp model. The stages used in this development model are only stages 1 to stage 2, namely the initial investigation stage, the prototyping phase which concurrently tests the validity and practicality. The research instrument used is a validation questionnaire, a one-on-one test questionnaire that is useful for seeing the practicality of e-Modules by teachers, small group test questionnaires that are useful for seeing the practicality of e-Modules by students and interview guidelines. Based on the validator's assessment, the results of the validity of the Android-based e-Modul using the Sigil software were 90.33% with a very valid category. The final value of practicality with the teacher obtained a final score of 80% in the practical category. The final value of practicality with students was obtained 88.61% with a very practical category. Based on the results of the study, it can be concluded that the Android-based e-Module using Sigil software in Data Presentation in class VIIA SMP N 24 Padang is valid and practical for use by teachers and students.
