Abstract
This chapter presents some of the most important developments in contemporary constructivism and demonstrates their connections to Pragmatism. It first offers a survey of basic constructivist assumptions and different constructivist approaches, then briefly elaborates on some connections between social constructivist approaches, especially the Cologne program of interactive constructivism and John Dewey's Pragmatism. To provide a more detailed survey, it outlines some basic features and perspectives found in those versions of constructivism that are most important in current discussions. The chapter distinguishes among at least five influential constructivist movements: German methodical constructivism and culturalism, social constructionism, pragmatist constructivism, situated cognitive constructivism, and interactive constructivism. Contemporary constructivist approaches waver between these poles of strength and weakness. However, discussions show that it is possible to further develop the strength of constructivist arguments if constructivism endeavors to discursively elaborate and justify its own claims to validity and truth.
