Advocates for multi-age education believe children flourish in environments where youngsters of different ages learn together in settings that feature collaboration, leadership, empathy, and social awareness along with academic achievement.

A Catalyzing Conversation with Dr. Sandra J. Stone and Peter A. Barnard, educators who have profound knowledge and experience about multi-age learning. Hosted by Plexus Catalyst Prucia Buscell.
