The question of how children represent and use comparative or partially ordered information is examined. Two experiments tested a conjecture that a common representation, a linear order, underlies the processing of all comparatives. (Author/MS)

Results confirmed that children differentially use knowledge of results and suggested that any description of motor skill acquisition must account for the complex interaction between developmental level and the difficulty of the task at hand. (Author/DB)

The main focus of this paper is research on the content dimension of feedback, although the scheduling of feedback in an instructional program is also briefly considered. The two major categories of the content of feedback discussed are motivational, reinforcing feedback and informative, corrective feedback. It is noted that researchers in the…

Examines the knowledge construction processes of novice programmers using parentheses and quotes in hypermedia; identifies characteristics of successful and unsuccessful students working off- and on-line. The strategies of perceptual matching and computer feedback were used in both settings to interpret of the information presented. (Author/AEF)

This study was designed to investigate the effects of modeling or training with and without rule provision on the employment of strategies in solving four-dimensional, discrimination-learning problems. Subjects were 144 second and sixth-grade children from the New York City Public Schools. The blank-trial hypothesis testing paradigm was used. The…

The effectiveness of the Delphi Technique is evaluated in terms of immediate and delayed controlled information feedback (feedback within 5 seconds as compared with a 24-hour delay); and the relationships that exist among measures of integrative complexity, estimations about the time of occurrence of future events, and time delay between task…

This document, containing 15 articles and 2 abstracts, is a report on the current status and progress of speech research. The following topics are investigated: phonological fusion, phonetic prerequisites for first-language learning, auditory and phonetic levels of processing, auditory short-term memory in vowel perception, hemispheric…

The work of a three-year series of experimental studies of human cognition is summarized in this report. Proglem solving and learning in man-machine interaction was investigated, as well as relevant variables and processes. The work included four separate projects: (1) computer-aided problem solving, (2) computer-aided instruction techniques, (3)…
