ust as play requires rules to keep a game going, inquiry needs structure and boundaries to be effective. As compared with more traditional delivery models of teaching and learning that focus only on pre-existing knowledge or skills, inquiry remains open to the unknown, to the ‘not yet.’ As teachers are considering inquiry in a particular topic it becomes helpful to consider how students might ‘play’ within in topic, that is, maintain an emphasis on what is already known (the foundational concepts or key-ideas) while allowing for space for the unknown where students can create, design, interpret or participate.
