This study of one part of the cognitive system of an illiterate Indian (his method of enumeration, computation, and evaluation) demonstrates the sophisticated conceptualization of which he is capable, independent of a writing system. (Author/CMG)

Comments on four articles in a special issue of the Journal of the Learning Sciences on methodology in learning sciences. Analyzes the articles within a general model seeking to analyze human activity across multiple time scales. (Author/MM)

Memory-based and constructionist processes have both been proposed as essential components of the activation of concepts (e.g., propositions) and the establishment of meaningful connections between concepts during reading. In this article, we argue that a comprehensive theory of reading comprehension should include both sets of processes. In…

Addresses the mind/brain relationship in terms of scientific theory based on philosophical inquiry. Examines each of the proposed theories about mind/brain relationship--such as identity, dualism, interactionism, materialism, physicalism, and mentalism--not only in terms of logic, but also in terms of the database to which the theories refer. (PS)

Introduces a systematic methodology for the analysis of covert or latent group talk, along with a set of operational procedures of validation. The methodology is related to analogical reasoning. (RC)

Describes the provenance of the data used in this issue. Includes design of the instructional sequence, instructional activities, classroom structure, and classroom episodes. (Author/MM)

The term, "schema," used largely as a descriptive convenience rather than a theoretical guidepost in social psychology is examined through an analysis of its development, function, and structure. This paper articulates a model of schema development in adults by defining a schema as a representation of some stimulus domain and a set of…

The difficulties and misconceptions that many students experience when learning to visualize graphs of functions are discussed. Specifically, the inability to make accurate connections between symbolic and graphical representations, the lack of understanding about scale and scaling, and the confusion caused by transformations are examined with…

A general model of conceptual change which is largely derived from current philosophy of science, but which can illuminate learning as well, is described. Some features of this model are illustrated by interviews with students studying special relativity in physics. Finally, some pedagogical implications are presented. (Author/PB)

Presents a view of the interplay among the various factors of personal experience, language, and socialization in the process of learning science in classrooms. Discusses the problematic relations among scientific knowledge, the learning of science, and pedagogy. (GLR)

Although teachers may sequence instructions carefully, they are unable to respond to the complex unique experience of each individual learner. Divergent production should be an instructional choice that enables individuals to learn through their own recall and idea construction. Learning is problem solving; when individuals do not know how to deal…
