Can children really learn independently? Falko Peschel led a class through elementary school for four years without teaching. During this time, the high achievements of the children not only amazed him but also many visitors repeatedly. Why is an open teaching approach that relies on children's self-regulation so effective – and what does it look like in practice? In Part I, Falko Peschel develops current teaching methods such as free work, weekly planning, station work, workshop, and project-based learning into a radical understanding of open teaching. He reviews his experiences and organizes them into overarching concepts before the subsequent volume presents daily teaching practices in language, mathematics, science, etc., in a concrete manner with many practical examples and teaching aids. In Part II, Falko Peschel now specifies this on a subject-didactic level.
