This chapter begins with an outline of the European context within which the twenty six research papers presented in this book emerged. A particularly important aspect of this context is Network 27 on Didactics, Learning and Teaching of the European Educational Research Association (EERA) which formed the core of the research community in which this work was developed over a five year period (2006-11). The next part of the chapter provides an overview of the six sections which make up the structure of the book as a whole. A discussion then follows of the clear continental divide with respect to didactics, learning and teaching in the European landscape which is based on the references used by the contributors to this book. This leads to a consideration of the historical origin of present-day didactics which can be traced back to a common heritage in the work of Jan Amos Comenius (1592-1670) in order to provide a platform in the search for common ground. In the section which then follows there is a discussion of the didactic triad as a tool for holding the complexity of teaching-studying-learning situations and this is considered in an expanded context in which classroom interaction in the school is placed within a wider societal context. Based on a review of the contributions to this book, the final parts of this chapter consider existing knowledge gaps between different national traditions and also identify themes that form the basis for building and extending common ground. The themes that have been identified through this process of synthesis relate to pedagogical content knowledge, learner knowledge, joint didactical action, curriculum research, the so called shift from teaching to learning, the philosophy of Bildung and its practical implications, links between theory and practice and the significant role of experimental schools. Finally these themes are proposed for consideration within the wider research, policy and practice community as the basis for future international co-operation that offer the potential to advance mutual understanding and common insights in this fiel
