Product Description

Philosophical Enquiry in the Classroom

Each session in this practical book offers an imaginary situation, followed by a series of questions to encourage children to challenge key philosophical ideas such as values and ethics, gender and identity, and existence and beauty.

All the enquiries have been tried and tested, and a handy star system is included to indicate the difficulty level of each one.

With a comprehensive introduction and key sections on the philosophy behind the experiments, this book also includes an online teacher's resource to guide practitioners through using the sessions to best effect in the classroom.

 “'This is a timely and valuable contribution: a capacity to think critically is the key component of any education, and Worley is an inventive enhancer of children's ability to think for themselves.'” –  A.C.Grayling, Professor of Philosophy, Birkbeck College, University of London, UK,
