Secondary schools are often missing practical approaches to teaching GIS topics. Nowadays, teachers teach about GIS rather than with GIS. We show an educational pilot project „Prakticky s GISy“ as an example of possible „good practice“ of teaching with GIS at several south moravian grammar schools. The aim of our paper is to discuss if this approach is dynamized method of current teaching standards belongs to the geography in the 21st century or if it is new and innovative approach to deeply rooted curricular documents. Through our project we try to make GIS more active at geographical lessons at secondary schools with peer-to-peer students and teachers participation. The base of our methods lies in using open source technologies directly in educational process.
