Argues that the failure to identify concepts and definitions with their corresponding levels of discourse has resulted in the propagation of historically outdated definitions and vocabulary in chemistry textbooks. Provides several examples of the problem from textbooks. Contains 36 references. (DDR)

Fifteen children (grades 3-5) with specific language impairment (SLI) were asked to define 10 common nouns. Children with SLI scored significantly lower than children with typically developing language for both content and form. Results suggest that lexical access and/or lack of metalinguistic knowledge were potential causes for the lower scores…

A survey of 218 learning disabilities experts found only 30 percent believed IQ-reading achievement discrepancy should be a marker of reading disability. Over two thirds selected three markers: reading achievement, phonemic awareness, and treatment validity. Over 75 percent believed exclusion criteria should remain part of the definition with…

Confronts 3 large lacunae in research on reading fluency: definition, component structure, and theory-based intervention. Presents a developmental- and component-based definition of reading fluency. Discusses how different types of current fluency interventions correspond to particular components in fluency's structure and to particular phases of…

Four issues facing the field of learning disabilities are discussed: (1) defining learning disabilities in terms of discrepancy scores; (2) delineating the boundaries of how specific a learning disability must be; (3) identifying treatments with scientific credibility; and (4) implementing instructional policy that is in the best interest of the…

Discussion of J. Renzulli's Schoolwide Enrichment Model (SEM) finds that the model's focus on talent development allows increased access to opportunity, excellence, and equity for minority students who have been shut out of gifted education. (Contains references.) (Author/DB)

Simulated data were used to demonstrate that groups formed by imposing cut-points based on either discrepancy or low-achievement definitions of learning disabilities (LD) are unstable over time. Similar problems were demonstrated in longitudinal data from the Connecticut Longitudinal Study, where 39% of the children designated as having LD in…

Significant limitations in research on learning disability (LD) have included failure to incorporate well-validated guiding theories, use of vague or nonspecific operational definitions, and lack of a systematic framework and common terminology for LD identification. Difficulties in communication among researchers continue to limit theoretical…

The definition is an important language form in the register of mathematics. Students need to understand the structure of a definition so that they can make sense of the definitions they encounter and so that they can construct their own definitions as part of organising their thoughts about the concepts they have explored. This article suggests…

This commentary on the article by B. Gawronski and G. V. Bodenhausen (see record 2006-10465-003) highlights the strengths of the associative-propositional evaluation model. It then describes problems in proposing a qualitative separation between propositional and associative processes. Propositional processes are instead described as associative.…

The concept of imminent suicide is examined. A search of National Electronic Library for Mental Health, the Cochrane Library, PubMed, OVID and MD Consult databases was conducted using the terms "suicide, imminent." The term "imminent" frequently appears in the mental health literature, finding common usage among clinicians. It is also a legal term…

This article offers an explanation of standardized tests so that parents may understand the significance of their children's tests scores. Definitions of terms such as "percentile ranking," "norming group" and "criterion-referenced" are given. The author also questions the validity of high-stakes tests as a true…

The term autonomy has multiple meanings based on diversity in theoretical views in current educational literature. Examples are given of multiple meanings of autonomy, and comparisons are made to the Piagetian view of autonomy as self-regulation implying separateness within community. A case is made for the relevance of autonomy as an educational…

Studies in a variety of countries have shown increases in the prevalence of overweight among children in recent years. These increases have given rise to concern about children's health and well-being. The terminology used in these studies varies considerably. However, whatever the terminology used, such studies are generally based on weight…

This study primarily aimed to suggest a theoretically and empirically valid definition for the construct of teachers' competence in environmental education. The study was designed and developed in two phases. We first attempted to formulate a hypothetical model of teachers' competence in environmental education, based on a specification of the…
