It is widely agreed that linguistic aptitude and motivation are key factors in the language learning process. However, there is a tendency to neglect a “dark” side of one of them: demotivation. It is important, for example, to reflect on the cause of high dropout rates worldwide, not only at a organizative level but also in the classroom. This workshop will familiarize participants with theory and practice related to demotivation and provide concrete recommendations on how to avoid demotivation in language instruction.
