Experimenter's sex appears to be an important factor in conservation assessment at the first-grade level. (RL)

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…

This activity explains fisheries resource management to seven-year olds. First-grade students learn concepts such as offspring viability, life expectancy, and distribution of species, which help to determine when, where, and how people fish and the importance of fishing responsibly. Lists materials, procedures, and extensions. (SJR)

This study investigated the relationships among mathematics achievement scores of first graders, the order of presentation of difficult topics, the use of readiness activities, and scores on a conservation test. The study was developed and conducted in four phases. Phase 1 included analysis of 70 randomly selected first-graders' work on the…

A former editor of this journal, 1967-69, selects an outstanding article from her tenure for its significance as the beginning of important studies in mathematics learning in young children. The article selected presents a modified technique for assessing a young child's acquisition of length conservation while eliminating or reducing the…

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…

A Piagetian framework is provided for understanding patterns of cognitive growth and their relation to early reading achievement among kindergarten children. Reference is made to relevant research, including recent Piagetian interpretations of prereading, language, and logical thinking. Instructional strategies are offered to guide kindergarten…

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)

Children completed three types of equivalent cardination tasks which assessed the influence of different stimulus configurations (linear, linear-nonlinear, and nonlinear), and density of object spacing. Prior results reported by Siegel, Brainerd, and Gelman and Gallistel were not replicated. Implications for understanding cardination concept…

Assessed the authenticity of conservation attainment through an observational learning paradigm. First grade children (N=60) were exposed to either a peer or adult model who was either present or absent during a series of tasks. No correlation was found between social influence and observational acquisition of conservation. (Author/JAC)

Programed instruction accelerated the ability of 62 children, ages four to six, in acquiring the concept of number conservation. (CP)

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