Teachers teaching teachers – By Geneal G Cantrell & Gregory L Cantrell

Abstract

the ISBN-13 has become "the ISBN"; publishers should no longer use ISBN-10. ISBN-13 starts with 978-, has the first nine digits of the old ISBN-10 next, and ends with a new check digit.You can not remove the 978-and obtain the ISBN-10, as the check digits differ. When 978-ISBNs start to run out, 979-ISBNs will appear.As far as we can, BJET will use the new form of ISBN from now onwards. van den Akker, J et al ed (2006) Education design research Routledge (Abingdon UK & New York) ISBN 0-415-39635-2 163 pp £24.99 www.routledge.com
