This book is the first that presents an overview of the main topics involved in the study and implementation of Computer-Supported Collaborative Learning (CSCL) from a learning viewpoint. It is also one of the few - or the only one - that does this from a research and practical instructional design perspective. Too many books begin with the medium and/or the environments used for CSCL, as if you would write a book on building a house by focusing almost primarily on hammers, saws and screwdrivers. The main topics are clustered in four sections that are derived from reverse ordering the CSCL acronym, because CSCL is all about learning through collaboration that is supported by computers. Although CSCL is increasingly advocated in higher education, specific CSCL implementations - i.e. something more than providing technology without a well developed educational rationale - are uncommon in higher education. The topics covered in this book, each including a review and several examples of current best practices in higher education, can stimulate 'informed' implementation of CSCL in higher education.
