In this essay, Susan Engel argues that curiosity is both intrinsic to children's development and unfolds through social interactions. Thus, it should be cultivated in schools, even though it is often almost completely absent from classrooms. Calling on well-established research and more recent studies, Engel argues that interactions between teachers and students can foster or inhibit children's curiosity. She offers an explanation for why curiosity is not a priority in our educational system and calls for greater attention to children's interests and explorations, which, she argues, are the mechanisms that underlie authentic learning.
