New theories and theory-based methodological approaches have found their way into Comparative Education - just as into Comparative Social Science more generally - in increasing number in the recent past. The essays of this volume express and critically discuss quite a range of these positions such as, inter alia, the theory of self-organizing social systems and the morphogenetic approach; the theory of long waves in economic development and world-systems analysis; historical sociology and the sociology of knowledge; as well as critical hermeneutics and post-modernist theorizing. With reference to such theories and approaches, the chapters - written by scholars from Europe, the USA and Australia - outline alternative research agendas for the comparative study of the social and educational fabric of the modern world. In so doing, they also expound frames of reference for re-considering the intellectual shaping, or Discourse Formation, of Comparative Education as a field of study.
