In our project the students are working with information and communication technologies to teach a topic that is connected to science, technology, engineering and mathematics. The pupils themselves choose the topic. It has to be motivating and activating. The students are creating different kinds of products like videos and quizzes in order to teach the students of their partner school. So everybody will work with pleasure, is creative and gets more responsible. After testing the products of the partner school, they have to give feedback about every product and - if necessary - revise their own products.
