Fractures between theory and practice are no rarity, particularly in the teaching of mathematics. The aim of the project is to overcome these fractures through real application situations, for example in crowd management, i.e. the movement of masses of people, with the help of computer simulations. The Lake Constance region, with its many innovative companies has to face worldwide competition – and the best minds too. The fast pace of change requires a high level of adaptability, with the corresponding requirement for lifelong learning. Seamless learning starts with fragmented learning experiences: What is learned in school is not used in later studying; studies or further training do not provide the elements relevant to practice. The aim of seamless learning is to overcome fractures – between individual learning stages, between the school and occupational areas, and from analogue to digital. New technologies are also deployed. Fractures arise, among other things, because the teaching of mathematics has unfortunately had little to do with real applications up to now. Mathematical models should demonstrate how crowds of people, for example at major events, can be moved safely. Existing software can simulate this and serves event management students as well as engineers or software developers in terms of basic teaching. The research project therefore aims to develop a teaching prototype on the topic of crowd management, to test this in teaching, and to make it available in corresponding networks in the Lake Constance region. The aim is also to bridge the “generation gap” between teachers and students in technological matters: On the one hand independent learning and development without use of the Internet will be encouraged. On the other hand e-learning technology will be used. The project will also decrease learning fractures between theory and practice as well as between the individual stages of school. Mathematics – often a major hurdle – can thereby be put across in an appealing way, using a specific example that is relevant to practice.
