Interaction pattern
From Teflpedia
An interaction pattern (/ˌɪntəˈrækʃən ˈpætə(r)n/) is a pattern in how students interact [1]
See for example; individual work (S), pairwork (S-S), groupwork (Ss-Ss), teacher to whole class (T-Ss).
Varying interaction patterns is a good idea to keep them on their toes.
