Since a discourse community may have its membership assigned both on the basis of speech or of writing, it follows that the concept of discourse community needs to be both medium-neutral and unconstrained by space and time. The defining characteristics of a discourse community might be (1) communality of interest, (2) mechanisms for…

Explored deductive inference processes in concept learning in four age groups. Results confirm findings of age differences in concept problem solving, with likelihood of solving the problem lower in older adults. However, solvers of all ages made the same correct inferences. (Author/JAC)

Three experiments using university students explored what constitutes an event and what determines its boundaries. Results supported the hypothesis that sequences of stimuli repeating in different contexts are cut out to become cognitive entities ("things" with a beginning and an end) in their own right. Results suggest that the…

A major goal of mathematics teaching is the involvement of students in the personal process of discovering mathematical ideas and formulating problems. The process of an inductive leap followed by a deductive argument is used in mathematics courses at Phillips Exeter Academy (New Hampshire). Mathematical problems are presented in which the givens…

The handbook, capsulizing much of the growing body of research and writing on conceptual approaches, is designed to provide assistance to elementary teachers in giving students a conceptual perspective for dealing with social studies content. The handbook is arranged in seven sections. After a brief discussion of the rationale for teaching…
