Conservation ability, spatial motor ability, age, and gender were used as predictive variables in a study of 26 kindergarten children's computer programming ability. A preliminary pilot study with first graders had suggested that programming success was related to the ability to reverse thought processes. In both studies, children were taught to…

Investigated was the learning of the mathematical uses of "more,""fewer," and "less" at a very early stage in the development of ideas. (CW)

Describes study that investigated whether the use of LOGO accelerates cognitive development of five- and seven-year-old kindergarten students as measured by Piagetian-based tests of conservation of length, number, and ability to identify geometric shapes. Pretests and posttests are described and directions for future research are given.…

Appraises the respective contribution of initial competence and of imitation of modeled response in the observational learning of conservation among first grade children. (HOD)

A study was conducted to investigate the respective contributions of personal and social factors (initial competence and imitation of modeled responses) in children's observational learning of conservation. Subjects included 180 first-grade nonconservers from six schools attended by French-speaking middle class pupils. All subjects failed…

A longitudinal investigation was conducted on the development of conservation skills in learning disabled (LD) children. During each of 3 years, six measures of conservation from the Concept Assessment Kit (space, number, substance, weight, continuous quantity, and discontinuous quantity) were administered to 31 newly identified LD students and 33…

This study investigated: (1) the relationship between the development of information processing capacity and certain Piagetian logical reasoning abilities; and (2) how the development of these cognitive abilities related to acquisition of certain measurement concepts. Forty first-grade children were individually administered tests of conservation…

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)
