Abstract

This study aims to determine the development process, practicality, validity level, and media effectiveness digital book with CTL (learning model Contextual Teaching and Learning) to improve students’ mathematical economic problem skills. The research method used is R & D research using the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). Research Subjects are seventh grade students of SMP Negeri 4 Semarang in 2019/2020 academic year. By choosing two classes namely class VII E as experimental class and VII G as a control class Before being tested in teaching materials validation tests were conducted by media experts, material experts and media design experts. Results of media, material, design expert validation. media, student responses and teacher responses have good criteria, namely for media experts, 93.33% were obtained, instructional media design experts 80.88%, material experts obtained 87.3%, the media was feasible to use, and teacher responses 87.5%, and student responses 87.05%.The media is practical to use.
