Focuses on students' ability to explain their ideas in writing who were able to demonstrate a high level of scientific concept understanding during discussion. Indicates that scaffolding the writing process both at the sentence level and the text level facilitates an improvement in the expression of scientific knowledge. (Contains 14 references.)…

Looks at patterns of conceptual encoding in American Sign Language (ASL), drawing from adults' retellings of a story. Results suggest that ASL encodes a great deal of conceptual information about motion events, significantly more than English and presumably more than most other spoken languages. (Author/VWL)

Presented successive auditory time gatings of unfamiliar words--familiar, phonologically-related words and familiar, phonologically-unrelated words--to school-age children with and without specific language impairments (SLI). The groups did not differ significantly in the point at which they recognized familiar words, but the subjects with SLI…

Uses a methodology for probing systems-thinking developed and used to investigate the way children (N=35) think about the natural environment. Findings suggest that eight-year-old children are capable of this type of thinking. (DDR)

This study examined effects of individual differences in speak-span scores and variations in memory demands on class-inclusion performance of 10-, 13-, and 15-year-olds. Results from regression analyses and the mathematical model indicated that differences in age, speak span, and memory load affected performance. Effects of speak span and memory…

Focuses on the quantum atomic model Electronium. Outlines the Bremen teaching approach in which this model is used, and analyzes the learning of two students as they progress through the teaching unit. (Author/MM)

Suggests an account of transitivity and transitive inferential reasoning differing from classic Piagetian and current information processing accounts. Postulates a three-component psychological system, with components relying on perceptual, linguistic, and conceptual subprocesses and sensitivity to simple cues. Maintains that the framework is…

Argues that the compartmentalism of structures observed in mixed languages is the result of the cumulative effect of different contact mechanisms. These mechanisms are defined in terms of the cognitive and communicative motivations that lead speakers to model certain functions of language on an alternative linguistic system: lexical…

Comments on an article that argues that the compartmentalism of structures observed in mixed languages is the result of the cumulative effect of different contact mechanisms. (Author/VWL)

Comments on an article that argues that the compartmentalism of structures observed in mixed languages is the result of the cumulative effect of different contact mechanisms. Argues that compartmentalization, as discussed in the article, does not offer any new explanations over earlier theories. (Author/VWL)

Offers both complementary and critical comments on an article that argues that the compartmentalism of structures observed in mixed languages is the result of the cumulative effect of different contact mechanisms. (Author/VWL)

Comments on an article that argues that the compartmentalism of structures observed in mixed languages is the result of the cumulative effect of different contact mechanisms. (Author/VWL)

Comments on an article that argues that the compartmentalism of structures observed in mixed languages is the result of the cumulative effect of different contact mechanisms. Discusses problems in three areas of the analyses. (Author/VWL)

Comments on an article that argues that the compartmentalism of structures observed in mixed languages is the result of the cumulative effect of different contact mechanisms. Takes issue with two points: the distinction made regarding various types of mixed languages and the characterization of secret languages as mere varieties of non-mixed…
