The third issue of the Bauhaus Journal is titled Experiment: Learning Communities and features a diverse set of contributions that look at learning communities from a contemporary and historical perspective. In one way or another, these communities have contributed on an ongoing basis to the creation of alternative learning environments in art, architecture, and design. Katja Klaus at the Bauhaus Dessau Foundation invited the authors of this new issue to explore the question of how pedagogical reform attempts shaped past ideas of education and community. Some of these attempts continue to develop today in various pedagogical approaches and schools. In their essays, the authors analyse how teachers and learners come together to shape their en- vironment, share knowledge in neighbourhoods, and try out new, experimental ways of shaping society and learning and living together.
