This diploma thesis presents a combination of the Schulatlas Steiermark and the use of smartphones in the subject of Geography and Economics in secondary education. The paper does not only highlight the advantages and disadvantages of the connection of an established tool with new technology, but also integrates the methodology into the context of the subjects didactics. The main focus of the study is concerned with the extent to which technology, especially smartphones, is facilitating or interfering competence-based working with the Schulatlas Steiermark in school. In order to investigate the qualitative circumstances of working with smartphones and the Schulatlas Steiermark, and to ensure a competency- and action oriented working of the learners, a case study was conducted, in which two lessons were held in one class. The results of the study show that the Schulatlas Steiermark as well as smartphones, are suitable for geographical and economic teaching contents; however, it is advisable not to combine the two. Because of the screen size of smartphones, the work material and maps of the Schulatlas Steiermark are not presented in an ideal way and are difficult to comprehend. In summary, both teaching tools used separately can facilitate future-oriented Geography and Economics lessons, which are close to the environment of the students.
