On the basis of these findings, both the measurement techniques of previous studies and Piaget's analysis of seriation are challenged. (Author)

Kindergarten and first-grade children participated in a study of the role of reciprocal and inversion reversibility in language acquisition and cognitive development. Subjects completed cognitive tasks assessing conservation, seriation, and class inclusion, and language tasks assessing the active-passive transformation and the negative…

Seriation refers to the process of ordering objects along single or multiple magnitude dimensions such as length, weight, and color. The ability to order objects in terms of some attribute is essential for the child's understanding of the properties of numbers. This study investigated the effect on seriation performance of increasing both the…

This study investigated: (1) the level of thinking of the Iteso Primary School children in Uganda; and (2) whether abilities involved in the Piagetian tasks of conservation, classification, and seriation develop at the same rate. The subjects, ages 6 to 13 (the period of the 7-year African primary school) were interviewed in their own language and…

To investigate reasoning capacities involved in learning to read, a Test of Multiple Seriation (from Piaget) was developed. Problems of a test used by Lunzer and Dolan are discussed. Results showed that word recognition and reading comprehension at age nine correlate significantly with multiple seriation, independent of IQ. (Editor/SJL)

Studied effectiveness of instruction in seriation and classification for kindergartners cognitively lagging behind their peers. Found that extensive classification and seriation instruction in a variety of formats was particularly helpful in facilitating cognitive gains for struggling kindergartners. Individualized instruction provided children…

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…

Kindergartners who had been taught to classify serials and conserve numbers through learning set procedures were retested one year later and compared with control children. Significant cognitive gains initially resulting from special intervention increased. (Author/BB)

Key elements in the construction of an operation were an integral part of an empirical study designed to test practical, pedagogical implications of the Piagetian model of cognitive growth. A total of 49 kindergarten children were pretested to determine their levels of seriation and classification operations. Pretests were conducted with a battery…

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)

Whether physical activity and verbal communication would affect kindergarten students' scores on the Metropolitan Readiness Tests (MRT) was investigated. Twenty subjects were administered Level I of the MRT when they entered kindergarten. For 5 days per week for 4 weeks, the 10 subjects in the experimental group worked at constructive play tasks…

To address the notion that the cognitive level of young children influences their ability to recall the logical sequence found in stories, four modes of language--story generation, retelling, dictation, and writing--were collected for three weeks from 35 second grade children. Through prior testing with the Goldschmid-Bentler Concept Assessment…
