The concept responds to insufficient support for developing geoinformation skills in Czech lower and upper secondary schools. It aims to create an interconnected system for developing geoinformation skills in teaching at lower and upper secondary schools, emphasising the implementation of GIS tools and proposing principles for the development of geoinformation skills in teaching. For this purpose, a matrix of learning tasks is created, arranged according to individual geoinformation skills – reading, selection, use, creation and sharing. The concept is intended mainly for pre-service and in-service geography teachers at lower and upper secondary schools, authors of school educational programs or teachers in non-formal education. The concept, including learning tasks and other materials, is available online at https://gitdoskol.ped.muni.cz.
