Looked for evidence of an intermediate stage between the second and third stages in multiple seriation during which subjects seriate the material on one dimension and classify it on the other. Fine grained analysis of stages is considered useful in elucidating the mechanisms of progression through a stage sequence. (GO)

Investigates the role of operative schemes in explaining older children's superior memory on past Piagetian memory tasks. Contrasts were made between the performance of normal v learning disabled grade school children, and between preschool children who either possessed or lacked seriation schemes. (Author/SS)

New conceptions of learning, analogy, and capacity have fundamentally changed scientists' view of cognitive development. New conceptions of learning help to explain how representations of the world are acquired. New models of analogical reasoning have suggested that logical inferences are often made by mapping a problem into a mental model, or…

This article discusses the challenge mathematics educators face in deciding what and how mathematics is to be taught, and offers some suggestions for teachers of young children based on Piaget's developmental theory of mathematics. Piaget's cognitive stages are briefly described and the concrete stage, which spans the age range included in early…

This unit of the Flexible Learning System (FLS), the second of a 3-volume series on children's thinking, focuses on the development of order relations (seriation) in children between 3 and 8 years of age. The series is based on the application of Jean Piaget's work to early childhood education. Seriation concerns the way children reason about…
