PENGRUH MODEL APTITUDE TREATMENT INTERACTION (ATI) BERBANTUAN KINEMASTER TERHADAP KEMAMPUAN KOMUNIKASI MATEMATIS SISWA T.A 2022/2023

Abstract

The aim of this study is to find out whether there is an influence of the Aptitude Treatment Interaction (ATI) learning model on mathematical communication skills in the material Lines and Series Arithmetic at XIth Class of SMA NEGERI 1 AIR JOMAN in 2022/2023 Academic Year, which is taught using the Kinemaster assisted application. It is an application that can be used by a smartphone which is useful for editing various interesting videos by presenting a fairly simple display. This study uses a learning model (ATI) which contains a number of methods/ways in teaching students to improve students' mathematical communication skills. From the results of research conducted on 30 students at the experimental class and control class by giving questions in essay form, the learning results were even better. From this, it can be concluded that the ATI learning model has an effect on improving students' mathematical communication skills. Where the average student score increases from the previous score. .
