Teachers undertake much of their work alone in lecture halls, seminar rooms, or online. However, they are far from alone when it comes to developing the right teaching and learning formats and practical considerations about how to implement their ideas in their courses. The experience and ideas of Technische Universität Berlin’s 3,000 teaching staff represent a huge source of knowledge. A number of formats aimed at promoting a culture of exchange are open to all teachers, support staff and students. Teaching can only improve if seen as a joint project with everyone contributing to its success!
