First and second graders (n=81) were randomly partitioned into experimental and control groups. The experimentals were given experiences in sorting and seriating objects. Significant treatment and grade effects (p.01) were found on a seriation test, but no significant relationships between classification and transitivity nor seriation and…

This study compared the effects of a formal, an open-framework, and a control preschool program on children's intellectual development. The formal program, based on Ausubel's and Piaget's theories, had a daily schedule of short prescriptive teaching sessions followed by related learning activities. The informal program, based on Piaget's theory,…

This study examines the development of children's understanding of temporal cycles and the relationship between cyclic concepts and cognitive development. A sample of 62 children, ranging in age from 4 to 10 years, were administered Piagetian tests of classification and seriation and a variety of specially designed cyclic tasks. (Author/JMB)

This study attempted to determine whether a combination of seriation and classification training would produce more general intellectual gains. (Author/SB)
