Most secondary schools try to use digital technologies in the process of education (they own PCs, notebook, projectors), and some own electronic teaching materials which are also available for their students. However, when it comes to use those technologies which students are a part of (smartphones, tablet, apps, etc.), schools are still behindhand. The aim of the project is focus on usage of smartphones/tablet computer in the lessons of natural scientific subjects (Biology, Chemistry, Physics, Geography). We are going to create mobile applications and teaching materials, which are going to be free and accessible to everyone (e.g. in Google Play).
