A Dutch policy scientist once said the information and knowledge in the twenty-first century has the shelf life of fresh fish, and learning in this age often means learning where and how to find something and how to relate it to a specific situation instead of knowing everything one needs to know. On top of this, the world has become so highly interconnected that we have come to realise that every decision that we make can have repercussions somewhere else. To touch as many bases as possible, we need to work with knowledgeable others from different fields (multiple agents) and take heed of their points of view (multiple representations). To do this, we make increasing use of computers and computer-mediated communication. If computer-supported collaborative learning (CSCL) is not simply a newly discovered hype in education, what is it and why are we writing a book about it? Dissecting the phrase into its constituent parts, we see that first of all CSCL is about learning, and in the twenty-first century this usually means constructivist learning. | What We Know About CSCL by Jan-willem Strijbos, Paperback | Indigo Chapters
