Children with mental retardation have pronounced difficulties in using cognitive strategies and comprehending abstract concepts--among them, the concept of sequential time (Van-Handel, Swaab, De-Vries, & Jongmans, 2007). The perception of sequential time is generally tested by using scenarios presenting a continuum of actions. The goal of this…

This study examines the effectiveness exercises based on the cognitive conflict, existing within the child, between two representational systems related to temperature: the qualitative-verbal one and the quantitative-numerical one as these relate to the advancement of children's understanding of the concept of temperature.

Three experiments using university students explored what constitutes an event and what determines its boundaries. Results supported the hypothesis that sequences of stimuli repeating in different contexts are cut out to become cognitive entities ("things" with a beginning and an end) in their own right. Results suggest that the…

Academic achievement of pupils working in small cooperation groups was compared to that of students taught in the traditional whole-class approach. Pupils in grades 2, 4 and 6 from small-group classrooms excelled on high level items; the groups did not differ on items measuring low level cognitive functioning. (Author/GSK)

The five chapters of this book discuss children's development and learning. Chapter 1, by Barbara Z. Presseisen, raises fundamental questions about schooling and learning. Chapter 2, by Robert J.

Variability stands in the heart of statistics theory and practice. Concepts and judgments involved in comparing groups have been found to be a productive vehicle for motivating learners to reason statistically and are critical for building the intuitive foundation for inferential reasoning. The focus in this paper is on the emergence of beginners'…
