Previous research indicates children reason in different ways about horizontal motion and motion in fall. At the same time, their understanding of motion down inclines appears to result from an interaction between horizontal and vertical motion understanding. However, this interaction is still poorly understood. Understanding of speed change may…

Science educators have long been concerned with how formal schooling contributes to learners' capacities to engage with science after school. This article frames productive engagement as fundamentally about the coordination of claims with evidence, but such coordination requires a number of reasoning capabilities to evaluate the strength of…

The impulse to investigate the natural world is deeply rooted in our earliest childhood experiences. This notion has long guided researchers to uncover the cognitive mechanisms underlying the development of scientific reasoning in children. Until recently, however, research in cognitive development and education followed largely independent…

We explore the immediate and longer term consequences of different types of instruction about a central topic in middle school science: the "Control of Variables Strategy" (CVS). CVS represents the procedural and conceptual basis for designing simple, unconfounded experiments, such that unambiguous causal inferences can be made. CVS…

This article examines cognitive models of peer learning in school and the implications that these models have for the teaching of science in primary schools. The article is a product of the European Commission, Socrates Comenius 2.1 funded project "The Implementation of Scientific Thinking in (Pre) Primary Schools Settings (STIPPS)" project…

Developmental assumptions that are frequently regarded as constraints on elementary school science curricula are analyzed. The argument that elementary school children cannot function as experimentalists because they have not yet attained formal operational thought is not supported by the Piagetian or non-Piagetian research reviewed.

"Let's Think!" is a cognitive acceleration programme aimed at developing thinking in children aged between 5 and 6. "Let's Think!" was described in "PSR" 69 (Robertson, 2001) using the acronym CASE @ KS1, as it was known before publication by NFER-Nelson. Since then, "Let's Think!" has spread beyond the…
