Constructivism has been traded as a new paradigm by its advocates, and criticised by its opponents as legitimating deceit and lies, as justifying a trendy post-modern "e;Anything goes"e;.In this book, Bernhard Poerksen draws up a new rationale for constructivist thinking and charts out directions for the imaginative examination of personal certainties and the certainties of others, of ideologies great and small. The focus of the debate is on the author's thesis that our understanding of journalism and, in particular, the education and training of journalists, would profit substantially from constructivist insights. These insights instigate, the claim is, an original kind of scepticism; they provide the underpinnings of a modern type of didactics oriented by the autonomy of learners; and they supply the sustaining arguments for a radical ethic of responsibility in journalism.
