Four Bachelor’s programmes at the Lucerne School of Art and Design – Interior Architecture, Object Design, Textile Design and Material Design – joined forces in a joint project during the autumn semester of 2010. The joint module has been this term for the seventh time with the same participating programmes, but with different interpretations of interdisciplinary. We want to take this as an opportunity to look back and compare our approaches of interdisciplinary, multidisciplinary and transdisciplinarity.
