In this study it was hypothesized that those students classified as conservers would score significantly higher on cloze passages related to the concepts of number, quantity, and volume than would those students classified as non-conservers. The subjects consisted of a group of 42 sixth grade urban public school students judged to be of low socio…

Based upon the relationship of the child's ability to conserve, as measured by Piaget tasks, to his success in beginning reading, this study compared the reading readiness of two groups of first-grade students. One group used Material Objects (Science Curriculum Improvement Study (SCIS)) and the other, Harper and Row's Reading Readiness Program.…

This study investigated the linguistic components of Piaget's class-inclusion task. First, hierarchical classification is examined from both Piagetian and linguistic theory points of view. Then, two general characteristics of child thinking that relate to the different interpretations of the responses to classification questions are discussed: (1)…

The relative effects of chronological age, mental age, IQ or Piagetian task performance were investigated among 143 Ss of high, average, and low IQ. Two kinds of group comparisons were made on fifteen tasks: (1) groups of the same chronological age, but different mental age and IQ, and (2) groups of the same mental age, but different chronological…

Two groups of kindergarten children had activities involving the transitive property of matching relations and length relations, respectively. Both groups had activities involving transitivity of weight relations. A control group had instruction only on relations. Pretests of Matching Relations, Length Relations, Matching Relations Conservation,…

The project, consisting of five experiments, attempted to develop remedial procedures and materials for retarded children with learning deficits in the area of arithmetic. Standardized training procedures were devised to facilitate development of operations (conservation, ordination, cardination, and classification) which J. Piaget describes as…

This study investigates the relationship of socio-economic status to the acquisition of two basic ideas underlying the concept of number conservation, "conservation of identity" and "conservation of equivalence." Tests for conservation of identity and of equivalence, detailed in the paper, were given to kindergarten, first, and second grade…

This paper examines some of the manipulative aids used in elementary mathematics instruction from the point of view of the cognitive structures needed to understand them. The number line, measurement activities, models for place value, and models for fractions are discussed. (SD)

Presents a classroom demonstration that illustrates the Law of Conservation of Energy. The demonstration utilizes a coupled pendulum device that can easily be constructed from ordinary monofilament fishing line and two metal pendulum bobs. (HM)

The author demonstrates that many secondary school students have poor concepts of area and point of view; she argues for diagnostic teaching with respect to formal geometry. Examples of diagnostic activities for determining the development of concepts of space are given. (MN)

A series of learning activities used in grades one and two to teach number conservation and arithmetic are presented in detail. The activity sequence is based on working with one-to-one correspondences for a lengthy period before introducing arithmetic operation. The author claims the approach is very successful. (SD)

Studies five-year-olds' relative number judgements of small and large number displays with and without perceptual aids. Children were found to respond to local rather than global density differences and to benefit from the provision of perceptual aids on both small and large number displays. (Author/AS)
