Good mathematics teaching requires elementary school teachers to recognize students' difficulties and problems in understanding mathematical content early on and to address them successfully. This is especially important in the case of common and systematic misconceptions, which have been extensively studied in mathematics education research. The DigiProMIN project aims to support teachers in addressing these misconceptions in the context of addition and subtraction in elementary school.

An essential component of the DigiProMIN project (digitization-related and digitally supported professionalization of MIN teachers) is the use of digital tools. The DiMa2 project has already developed a simulation that can be used to prepare student teachers at elementary schools for the later challenges of identifying misconceptions. This simulation is now being prepared and adapted for use in teacher training courses. This will give elementary school teachers the opportunity to train the recognition of misconceptions in the context of addition and subtraction in a simulated learning situation. In addition, possibilities to counteract such misconceptions and to use them productively are discussed in the context of teacher training.

The mathematical focus of the simulation and training modules is on the content areas of primary school teaching (grades 3/4). For quality reasons, the development of the training will be accompanied by experienced training experts and will also be empirically tested. The results will allow for a well-founded further development of the simulation and the teacher training during the funding period until 2025.
