The Influence of The Discovery Learning Model With The Help of Powerpoint Learning Media on The Mathematical Comprehension Ability and Self-Efficacy of Junior High School Students

Abstract

This study aims to determine the influence  of discovery learning learning models with the help of powerpoint learning media on students' mathematical understanding ability and self-efficacy. The method carried out in this study is quantitative using the type of experimental research. The population in this study was all grade VII students of SMPN 1 Puloampel, samples were taken using purposive sampling techniques  so that the samples obtained were class VII-A students as a control class and class VII-B as an experimental class with 25 students in each class. The data collection technique uses 5 items of essay tests, students' mathematical comprehension abilities, and self-efficacy questionnaires. From the results of data analysis, it shows that the discovery learning learning model  with the help of powerpoint learning media on students' mathematical understanding ability and self-efficacy is  better than conventional learning.
