Goals for adding philosophy to the school curriculum centre on the perceived need to improve the general quality of critical thinking found in society. School philosophy also provides a means for asking questions of value and purpose about curriculum content across and between subjects, and, furthermore, it affirms the capability of children to think philosophically. Two main routes suggested are the introduction of philosophy as a subject, and processes of facilitating philosophical discussions as a way of establishing classroom "communities of inquiry". This article analyses the place of philosophy in the school curriculum, drawing on three relevant examples of school curriculum reform: social studies, philosophy of science and Kura Kaupapa Maori.
