Our project is planned to apply the "Flipped Classroom" method at school when the schools are open and online when they are closed due to covid-19 to increase the success in lessons. In the "Flipped Classrom" method, unlike the traditional teaching method, the subject to be taught to the student is sent as Excel files, PDFs, visuals, pictures, videos beforehand. The student prepares for the subject in advance. The teacher's task is to guide.
