GRADES OR AGES: Four-, five-, and six-year olds. SUBJECT MATTER: Cognitive areas of symbolism, classification, conservation, seriation, spatial relationship, and temporal relationships. ORGANIZATION AND PHYSICAL APPEARANCE: The guide is divided into six sections, one for each of the above cognitive areas. Each section lists materials and describes…

Examines the issue of object sorting in early infancy. Forty-eight infants at 6, 9, and 12 months were presented with eight sets of small, manipulable objects. At six months, selective manipulation was absent; at nine months, 94 percent of the infants sequentially touched similar objects and at 12 months 100 percent did so. (Author/DB)

Matrix tasks to assess multiple classifications and multiple seriation skills were administered to 160 children (40 Ss each from preschool, kindergarten, first and second grade levels). Each child received six matrix subtasks (reproduction and transportation of cross classification I, double seriation, and cross classification II) in one of six…

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

Children aged 2-1/2 to 3-1/2 years in three preschool programs were given a test battery consisting of classification, relations, and conservation tasks. One program (Ausubelian) was formal and two programs (Piagetian and Tradition) were informal. Posttest data for the first year of a three-year longitudinal study indicated significantly superior…

Six mildly and moderately retarded children (ages 6-8) were instructed in the Piagetian constructs of unidimensional classification and/or seriation using the "Piacelleration" learning set technique. After one semester, subjects made significant gains on: classification and seriation tasks, the Peabody Picture Vocabulary Test, and the…

Describes longitudinal study of the development of understanding of two logical properties of number by 36 children during the first three years of primary school in Glasgow. Piagetian tests and number skills tests were administered to explore the acquisition of number as class and number as order concepts. (Author/LRW)

This study examined the effect of an innovative teaching activity to improve concrete operational thinking skills with preschoolers in Head Start programs. A "learning set" of classification games and seriation games was used to teach the oddity principle and insertion into a series. These games were played with the children using toy ponies and…
