Economic models are developed by consciously reducing the complexity of what is viewed with the aim of gaining knowledge. With the help of mathematical modelling, economic models are formulated more precisely. This result is an important tool for the determination and representation of system relationships. By visualizing the mathematical modelling with axis diagrams, abstract relationships can be identified and discussed. Economic axis diagrams are used in schools, among other things, as an aid for the systematic consideration of individual influencing factors of a complex interaction system, the formation of prices in markets.



The aim of this doctoral project is to answer the research question of the extent to which axis diagrams are tools and hurdles in economic education. Subject-specific barriers to understanding are identified and implications for economic lessons are deduced. While there is a wide range of research work on the diagram competence of students in the field of natural sciences, the domain-specific examination of the axis diagram competence in the context of economic education is still in its infancy.



In the interactive presentation, the described research project is briefly presented and the current state of research on learning barriers in pricing and the price-quantity diagram is shown. In a subsequent exchange of experiences, opportunities and limits of verbal explanation of the price formation, as well as graphic explanation of the price formation with the aid of the price-quantity diagram, are worked out on the basis of the audience's individual experiences.
