The summary of research on learning through play provided in the CEECD articles and accompanying commentary by Howe comes at a time when many play advocates believe that play is “under siege.” It also comes at a time when many Canadian early childhood educators are striving to secure a pedagogical focus on play in the development and implementation of early learning curricula. These reviews provide a valuable foundation for interpreting the available evidence on learning through play, as well as raising more fundamental questions about the significance of play in early childhood.
