“This video provides an overview of the background and rationale for high-leverage practice (HLP) 17 and demonstrates three key components of this HLP through video exemplars from real classrooms. The first key component is that groups should be highly structured and include clear directives. The second is that some groups should be homogeneous and others should be heterogeneous to provide an appropriate setting for the goals of the lesson. The third key component is that the use of flexible groups does not occur in a vacuum” (Kennedy et al., 2019).
