This toolbox on intercultural communication, developed for the 4TU.Centre for Engineering Education (CEE), addresses several questions teachers have on the topic. Here you can find good practices and materials, to find inspiration and ideas when teaching in an international classroom. The idea for the toolbox is for it to be a living document, by and for teachers, where teachers can share their practices. So, if you have a practice (good or bad!), website, course, article or something else that can inspire your colleagues, please send it to us. We will make sure the toolbox stays accessible, by placing everything in the right place.
