THIS PAPER NOT SENT TO GMU NOR TO ARIZONA. Main Point: The "span of immediate recall" has been discussed by at least three authors. What these works show is that individual human beings lack the mental capacity to recall more than a small number of concepts at any one time. This limited capacity severely restricts the individual’s ability to construct mental models of more than a small degree of complexity Education Serial Email Posting, dated 19 Feb 1996. I don't know to whom this email was posted. Possibly to TIPP faculty, since the closing paragraph urges some action by TIPP as well as GMU. The article deals with the magical number three concept. Note: Warfield wrote a series of these "email postings" three or four, and I tried to put the words "email" in the title of each one, so they could be located as a group.
