Demonstrates that conservation of amount does not always precede conservation of weight. Subjects were 60 six-year-old children. (BD)

Evaluates some possible reasons for the occurrence and eventual correction of children's naming errors in an experiment in which two-, four-, and six-year-olds learned two artificial object names in succession. (HOD)

This paper demonstrates a method for constructing long variables using items that elicit partically correct responses across ages. Long variables may be defined by students at different ages (year levels) attempting common items within a test containing other items considered to be appropriate for each age or year level. A developmental model of…

Working on the hypothesis that if readers had several alternative correct meanings of a given text set before them they would select the one in accordance with their abstract abilities and intellectual maturity, a study investigated the measurement of levels of meaning as illustrated in taxonomies and focused on the applicability of the taxonomies…

This research attempted to expand Piaget's study of children's thinking to include the content and the development of their concepts of death and the impact of experience on those concepts. One hundred twenty-two, middle-class, native-born boys and girls, aged three through twelve years were interviewed. Concepts were found to be composed of nine…

The term, "schema," used largely as a descriptive convenience rather than a theoretical guidepost in social psychology is examined through an analysis of its development, function, and structure. This paper articulates a model of schema development in adults by defining a schema as a representation of some stimulus domain and a set of…

Two studies explored the possibility of inducing conservation understanding in intellectually normal preschoolers and mildly mentally retarded children of comparable mental age. Retarded children, MA 3-10 to 5-0, received Verbal Rule instruction. Three- and 4-year-old children were given Verbal Rule training in a 2 x 2 x 2 factorial design…

Defines a generalization as "a descriptive statement of broad application indicating a relationship between two or more concepts." Argues that successful teaching about generalizations can only occur when students understand the relationship between concepts and facts. Discusses four issues and four approaches related to teaching…

Piaget's model of children's conceptual learning and development was compared with Klausmeier's Conceptual Learning and Development (CLD) model in a longitudinal study. The CLD model suggests four successive levels of concept learning: (1) concrete--recognizing an object which has been encountered previously; (2) identity--recognizing a known…
