ACKNOWLEDGEMENTS

This text is an adaptation of materials forming part of a Ph.D. thesis, The Concept of Activity in Education, accepted by the University of London in 1966. In rewriting this material for a more general readership I have had the benefit of valuable critical comments from the following friends and colleagues who have read all or parts of the manuscript: Jeanette Coltham, Ken Dagnall, David Hargreaves, Eric Hoyle, Philip Jackson, John Naylor, Geof Roberts, Raymond Ryba, Phil Walking and Keith Whalley. My grateful thanks are due to these and to my wife, who has also assisted with the numerous secretarial chores inseparable from work of this kind.
