I recently read about Chat Stations on the Cult of Pedagogy website and immediately saw how this could be very beneficial in the world language classroom. This classroom procedure gives students an opportunity to work cooperatively in the target language while moving around the room and working with different prompts.
The types of prompts can be as simple as makings lists for novice learners (fruit, vegetable, clothing, city locations), describing a photo for intermediate learners, or stating and supporting opinions for more advanced language learners. It is a fairly easy set-up and follow-up as a large group will be much richer once students have worked on the prompts in small groups. This type of activity is also an effective opportunity for formative assessment and feedback from the teacher as the teacher circulates among the groups and interacts as necessary to clear up any language issues that groups may struggle with. Here is a video from Cult of Pedagogy explaining how to use and set-up Chat Stations.
