PENGEMBANGAN MULTIMEDIA PEMBELAJARAN MATEMATIKA BERBASIS POWTOON PADA MATERI SEGIEMPAT KELAS VII SMP
The study aims to develop multimedia of Powtoon-based on valid rectangle materials in material and media. This type of research is Research and Development using the 4D research model Define (define), Design (design), Development (development) and Disseminate (disseminate). The research was conducted only until the validation stage by expert without direct field trials. The types of data obtained in the development process are qualitative data and quantitative data. The research tools used are the materials expert validation sheets and the media expert validation sheets. From the results of the validation obtained an average assessment score of 68,64% with calid criteria and the results of the media expert validation obtained an average assessment score of 80,59% with valid criteria. Thus it can be conclude that multimedia of Powtoon-based mathematics in rectangle material developed is declared valid and feasible to be tested in the field.
