ABSTRACT
Researchers have been afforded the opportunity of hearing and discussing some important ideas about the kinds of knowledge to be learned in schools, and about the ways in which they are learned. Many of these ideas are quite novel, and are of the sort that open up new horizons of thought about human learning and human information processing. Several of the chapters, either explicitly or implicitly, have called into question some prototypes of human learning, or of school learning, which are "old" in the sense of being familiar. Knowledge acquisition, in the sense that most investigators have conceived of it in this conference, is a matter of learning by using language. This is quite appropriate, and indeed it is important to emphasize that human beings do learn by using language. It should be noted, however, that this conception implies the assumption that students know how to use language, to comprehend it, in other words.
