This article presents a new method of inferring students' cognitive structures and their development. A modification of Reitman and Rueter's "ordered tree technique," the method generates a structure that displays important relationships assumed to be in a student's memory about concepts taken from a specific field of study.

The effect of educational television background music on selective exposure and information acquisition was studied. Background music of slow tempo, regardless of its appeal, had negligible effects on attention and information acquisition. Rhythmic, fast-tempo background music, especially when appealing, significantly reduced visual attention to…

Six-and eight-year olds were exposed to a modeling sequence for cluster rule learning under high, medium, and low degrees of structure. Age differences in vicarious learning emerged only in the medium structure condition, while immediately imitating a model failed to influence learning for either age group. (Author/CP)

This study showed that Oksapmin children not only spontaneously use the indigenous numerical system of their nontechnical culture but also have created new forms of numerical symbolization and calculation to deal with schooling arithmetic problems. Novel conceptual developments, factors mediating the schools effect, and the influence of prior…

Controversy, an aspect of small-group interactions, was investigated in 10 mixed-ability, mixed-sex, elementary math groups through analysis of dissension episodes. Results showed that boys and higher-ability students had significantly more prevailing answers and demonstrations. (Author/LMO)

A reading-specific multiple classification task was designed that required children to classify printed words along phonological and semantic dimensions simultaneously. Reading-specific multiple classification skill made a unique contribution to children's reading comprehension over contributions made by age, domain-general multiple classification…

Examined effects of conceptually based instruction on development of students' procedural flexibility. Students in primary schools in the Netherlands participated in one of two instruction programs: the Realistic Program Design (RPD) or the Gradual Program Design (GPD). In both programs, conceptual understanding preceded procedural skill. However,…
