Only recently, with the vigorous dialogue on constructivism and situated learning, have psychologists and designers resumed a substantive conversation (Duffy & Jonassen, 1992; Educational Technology, April 1993 special issue on situated learning; Wilson, in press). Psychologists such as Bransford, Perkins, Scardamalia, and Lesgold, who have taken on the challenge of design, have run up against many of the same problems addressed by traditional ID theories. At the same time, the perspectives of psychologists have stimulated reflection and renewal within the ID community. The net result of this interplay is a renewed recognition of the importance of design, as well as an array of new designs that take into account new technologies and theories of learning.
