MEDIA PEMBELAJARAN POWERPOINT SLIDE SHOW DENGAN KARAKTERISTIK REALISTIC MATHEMATICS EDUCATION

Abstract

The purpose of this research is to produce learning media with realistic mathematics education characteristics in Pythagoras class VIII theorem material. The reason for taking the title is because there is still a lack of learning media that is integrated into the technology developed by educators in the era of industrial revolution 4.0 now. This type of research is Research and Development concerning the first three stages of the 4D research model (Define, Design, Develop, Disseminate). This research is only done until the validation stage by experts without direct trials to the field. The data in the study was collected with questionnaires. The instrument used is a validation sheet by an expert. Data is analyzed with descriptive analysis. The data obtained is qualitative and then the data is converted into quantitative data using MSR. From the validation of material experts obtained an average assessment of 63.92% with valid criteria, media expert validation obtained an average assessment of 82.01% with very valid criteria and for validation, linguists obtained an assessment of 82.52% with very valid criteria. Validation results show that the teaching materials developed are declared very valid and worthy to be tested in the field.
