Pengembangan Media Pembelajaran Matematika Powerpoint Interaktif Berbasis Masalah Kontekstual Pada Barisan Aritmetika

Abstract

The background of this research is that students feel bored with learning mathematics and students do not yet know the benefits of learning mathematics itself. This is one of the problems that exist in the world of education. This research aims to develop valid and interesting interactive learning media for students. In the development of this media, it contains material for arithmetic sequences related to contextual problems. The type of research used in this research is Research and Development (R&D) with the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). The stage of testing the validity of the media was tested in 6 validators. The results of the validation got a percentage of 88%, 86%, 88%, 83%, 96%, and 95.5% with very valid categories. The next stage was implemented for students, this stage was tested on 30 high school class X students. Students are required to fill out a student response questionnaire to the media, obtaining an average percentage of 92% in a very interesting category. So that contextual problem-based interactive PowerPoint learning media is very valid and can attract the attention of students in learning mathematics.
