In a seminal article published in 2006, Jeanette Wing described computational thinking (CT) as a way of "solving problems, designing systems, and understanding human behavior by drawing on the concepts fundamental to computer science." Wing's article gave rise to an often controversial discussion and debate among computer scientists,…

Describes a set of terms (viscosity, hidden dependencies, imposes guess-ahead, abstraction level, and secondary notation) intended as a set of discussion tools for nonspecialists to converse about the structural features of a range of information artifacts. Explains the terms using spreadsheets as an example. (SR)

Definitions of four rare words were read to 259 undergraduates who were asked to record letters and syllables of the words, at the tip of the tongue. Results corresponded to an earlier study, with morpheme-like clusters evident. Results indicate an organizing memory system for words used in speech. (CHK)

To determine the effects of the amount and type of information supplied by a concept definition, fourth and eighth graders were presented with one of two definitions: a "technical" definition which precisely specified all defining attributes of the concept, and a "common usage" definition from a children's dictionary which did not specify all…

Evidence for speaker knowledge of morphological patterns, both derivational and inflectional, is not limited to productive patterns. Nonproductive patterns appear to be accessible in such a way that accessibility (a term preferred to "psychological reality") may be viewed as a function of four somewhat interdependent factors: (1) productivity, (2)…

This article provides an overview of definitions and measures related to school engagement. The intent herein, is to explore the construct and measurement of school engagement and related terms and provide a summary of previous literature, in an effort to offer a foundation to advance related scholarship and practice. Previous articles exploring…

A set of procedures for coding internal state words (those words representing mental states and perceptual experiences), developed for application to data on the language of young children and those with whom they converse, is described in this report. The report first discusses the rationale for studying cultural variation in vocabulary use, the…

Reviews the current literature concerning prior knowledge in an attempt to clarify problems with the terminology. Identifies the three main problems: lack of definition or vagueness, nominal versus real definitions, and different names/same constructs or same name/different constructs. Includes a conceptual map of prior knowledge terminology. (MJP)

This study explored two aspects of language expression (defining words and repeating sentences) in samples of 26 Downs Syndrome (DS) and 26 mentally handicapped (MH) adolescents and young adults matched on intelligence and chronological age. Testing included language tests, a comprehensive audiological assessment, and computer-based memory…
