Research designed to determine whether the phenomena observed by Piaget were task specific was performed. The results did not confirm Piaget's notion that topological concepts develop prior to the concepts of Euclidean geometry. (SD)

Presents a series of activities intended to enable teachers to determine if children are ready to be introduced to the concept of speed. Reviews Piaget's theories and the empirical evidence on which the sequence is based. (Author/CP)

A link between the acquisition of native-like second language pronunciation ability and certain personality constructs, such as empathy, is asserted. The influence of language on person and person on language is investigated. (Author/RM)

A longitudinal study of the acquisition and use of the English sound system by Japanese learners of English is reported. The variability model of sociolinguistics is used. (Author/RM)

A study is reported investigating whether reported sequence of acquisition of grammatical morphemes for second language learners would be found to exist in tasks other than that requiring speech production. (Author/RM)

Hypothesizing that subtraction of (negative) integers requires formal operations, the author describes a study of children's understanding of related concepts. The study involves the use of apparatus embodying properties of the number line. (SD)

Introduces biology teachers to the central ideas of Piaget's theory of intellectual development. Also presents a scheme of biology instruction and classroom procedures based on a Piaget-related theory of learning. (PEB)

Continuing an article begun in SE 514 442, the author discusses managerial aspects of implementing the integrated scheme proposed. (SD)

Presents a progress report on some methodological advances made on certain facets of the problem of the learning of a structure of a subject matter. (PEB)

Introduction: The aim of the paper is to propose new models of information behaviour that extend the concept beyond simply information seeking to consider other modes of behaviour. The models chiefly explored are those of Wilson and Dervin. Argument: A shortcoming of some models of information behaviour is that they present a sequence of stages…

Tests to discover the nature of the second language learner's language are discussed. Such tests are based on the assumptions that the development of the system of the foreign language in the learner follows certain regular patterns, and that the learner's grammar is essentially systematic at any stage of his learning. (RM)

This is the final report of a series of 19 experiments designed to study impasses in the learning of skills with a strong perceptual component. Several series of experiments were designed with the purpose of producing experimentally manipulable impasses or plateaus in the course of learning. Over 200 subjects (humans and animals) in learning…

A response to Richard E. Clark's conclusion that media research needs to stop emphasizing descriptive research and focus on prescriptive research designs and questions, this paper reiterates the distinctions between disciplines and applied fields of study, and suggests that these distinctions should be evident in the descriptive/prescriptive…

This review of the role of the metaphor in instruction begins with a brief description of historical thinking on the subject. Modern views of the metaphor as a psychological mechanism rather than just a figure of speech are then presented, with emphasis on reasons why metaphors should be helpful in education. It is noted that the hypothesis that…
