5 Foreword From October 3 to 7, 1993 the NATO Advanced Research Workshop on "The Design of Computational Media to Support Exploratory Learning" was convened at the exquisite Asilomar Conference Center in Pacific Grove, California, U.S.A. The attending participants were as follows: Mariola Alberti, Dipartimento di Scienze dell'informazione, Universita di Milano, Italy Augusto Chioccariello, Instituto per la Technologie Didattiche, C.N.R., Genova, Italy Kathryn Crawford, Department of Education, University of Sydney, New South Wales, Australia Al Cuoco, Education Development Center, Newton, MA, U.S.A. Andrea A. disessa, Graduate School of Education, University of California, Berkeley, CA, U.S.A. Laurie Edwards, Crown College, University of California, Santa Cruz, CA, U.S.A. Michael Eisenberg, Department of Computer Science, University of Colorado, Boulder, CO, U.S.A. Gerhard Fischer, Department of Computer Science, University of Colorado, Boulder, CO, U.S.A. Chris Hancock, TERC, Cambridge, MA, U.S.A. William Higginson, Queen's University, Kingston, Ontario, Canada Celia Hoyles, Department of Mathematics, Statistics and Computing, Institute of Education, University of London, U.K. Chronis Kynigos, Faculty of Education, University of Athens, Greece Colette Laborde, DidaTech, LSD2, IMAG, Grenoble Cedex, France Jean-Marie Laborde, DidaTech, LSD2, IMAG, Grenoble Cedex, France John Mason, The Open University, Milton Keynes, U.K. Erich Neuwirth, Institute of Statistics and Computer Science, University of Vienna, Austria Liddy Nevile, Sunrise Research Laboratory, Royal Melbourne Institute of Technology, Melbourne, Victoria, Australia

Uri Wilensky, Media Laboratory, Massachusetts Institute of Technology, Cambridge, MA, U.S.A. This book comprises an outcome of this workshop augmented by several chapters from those invited to the workshop but unable to attend. The financial support of the NAill Scientific Affairs Division-both for organizing and conducting the workshop and for preparation of this volume-was indispensable. Celia Hoyles was principal investigator (co-principal investigator, Andy disessa) and administrator of the grant from NATO. Laurie Edwards handled the local organization for the workshop. Bruce Sherin and Elizabeth McCullough acted as local support staff, including transport and setup of demonstration equipment on loan from the University of California, Berkeley and Santa Cruz. Finally, Academic Arts of Berkeley, CA provided technical editorial assistance, formatted and prepared camera-ready copy for the book. To all of these, and especially to authors of chapters for their contributions and patience during the extended editorial process, our sincerest thanks.
