Development of Android-Based Mathematics E-Module

Abstract

This study is research and development that aims to describe the process of developing an Android-based mathematics E-Module, to discover the results of developing an Android-based mathematics E-Module that is valid, practical, and effective, and show the specifications of an Android-based mathematics E-Module. The study subjects were students of grade XI TIPH at SMKKN Makassar, with 34 students. This study employed a 4D development model: define, design, develop, and disseminate. Expert validation data was obtained from filling out the questionnaire by the expert, the practicality data was obtained from observation of learning implementation and teacher's response questionnaires, and the effectiveness data were obtained from the student's response questionnaire and learning outcomes test. The data obtained were analyzed and interpreted in terms of validity, practicality, and effectiveness. The expert validators were used to examine whether or not the Android-based mathematics E-Module is feasible. The practicality questionnaire was used to discover the teacher's opinions about the ease of students in using the E-Module. The effectiveness questionnaire is used to determine students' opinions after using the E-Module, and the test learning outcomes to determine the student's ability after learning to use the E-Module. The study results indicate that the mathematics E-Module development process starts from the initial to final analysis stage until the E-Module prototype is produced in the form of an apk file format. The results of the development show that the average Expert Validation Value (NVA) of the E-Module and lesson plans are valid, the results of the implementation of learning and the teacher's response are in the very good category, so the E-Module is stated as practical, the results of students' responses are in positive category, and the average value of the learning outcomes are above the KKM, so the E-Module is stated as effective. The specifications of the E-Module contain Three-Dimensional Mathematics material.
