This paper examines how teachers develop and modify professional knowledge in response to experience and to new research knowledge. A discussion is presented on the interaction of propositional knowledge (the basic medium of classroom and research knowledge) and practical knowledge (the observable competence apparent in successful professional…

Secondary school geometry students have been found to have misconceptions concerning parallel lines. Correctional teaching programs did not seem effective in changing these misconceptions. This research describes an attempt to use teaching strategies which take into account current learning theory and which encourages students to be actively…

This paper describes further research on a learning procedure for layered networks of deterministic, neuron-like units, described by Rumelhart et al. The units, the way they are connected, the learning procedure, and the extension to iterative networks are presented. In one experiment, a network learns a set of filters, enabling it to discriminate…

The technical reports summarized in this paper were prepared as part of a project designed to determine what is known about the teaching of cognitive skills and to formulate questions relating to such teaching for further research. Topics discussed in the 22 reports include the following: (1) teaching thinking; (2) Aristotle's logic; (3) a…

To discover the relationship between cognitive development and writing, a means of assessing writing is needed that reflects accurately changes in the way children write as they grow older.

Focuses on the language used by elementary mathematics teachers and its relationship to students' understanding of mathematical concepts, as well as their misconceptions. Describes eight situations in which the use of precise, formal mathematical terms could be replaced by informal language, particularly when introducing new concepts. (TW)

Calls for differentiating between three kinds of studies of students' conceptions in science, namely descriptive studies, explanatory studies, and studies attempting to foster conceptual change. Cites the literature about student perceptions and science instruction. (TW)
