This conversation between Dr. Robert Gagné, and Dr. M. David Merrill, took place July 10, 1989 before an audience of about 200 at Utah State University.  A series of papers based on this discussion later appeared in Educational Technology Magazine. The conversation highlights the main points of Gagne and Merrill’s respective learning theories, and a comparison of the events of instruction, and Component Display Theory.
