Purposeful Grouping
Also, as this video explains, ELLs learn best when they are in heterogeneous classrooms. ELLs need to be given ample opportunities to have extended interaction (such as doing ‘jigsaw’-type activities) with peers of varying English proficiency levels, who can provide ELLs with a range of models for how to use English words or structures appropriately, as well as abundant, personalized feedback on ELLs’ own developing English use. It is best for ELLs if, within their classrooms, teachers sometimes group students heterogeneously according to English proficiency, and sometimes homogeneously, depending on the purpose of the task at hand.
