Constructivism and teaching: A new paradigm in general didactics?

After a long period of paradigmatic stability in the field of general didactics ( Allgemeine Didaktik ) in Germany, the proponents of the 'constructivist didactics' claim to be formulating a new approach on the theoretical as well as practical levels. This claim is analysed and evaluated. Four background theories of constructivist didactics are sketched; the central arguments of these didactics are reconstructed; some examples of practical constructivist teaching recommendations presented; and, finally, constructivist didactics is critically analysed in the context of a theory of learning in schools. The conclusion is that constructivist didactics is not a new paradigm in the sense that its proponents claim it to be.
