This is a detailed review of studies of extinction of Piagetian concepts, stressing that interpretation of such research is complicated by methodological problems, some avoidable, some intrinsic to the extinction paradigm; and that this paradigm retains the potential for contributing important information about the nature of concrete-operational…

This paper reports on a portion of a 14-year study of the mathematical thinking of a cohort group of students that was based on an identifiable perspective on how mathematical ideas are built. Three videotape episodes are presented so that groups of students working together can be viewed at three points in time: as fourth graders (ages 9-10) and…

Sixty Japanese children ranging in age from 3 years 4 months to 7 years 5 months were individually interviewed with three Piagetian tasks. Children's levels of representation were assessed by asking for a graphic representation of 4 dishes, 6 pencils, 8 small blocks etc. A conservation-of-number task was then given to assess children's level of…

This study observed and documented the changes of college students' notion of mathematics functions in a virtual environment that integrated a synchronous and asynchronous Computer Mediated Communication system. Four Arizona State University undergraduates were teamed into pairs and solved function problems in the virtual classroom over a one…

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

Study lends support to the view that the problem with left-right stems from the imperfect mastery of the basic discrimination, not from an inability to deal with the logic of relational concepts. (Author/CB)

An analysis of critical thinking is discussed in terms of conceptual interpretations and through determining the logic of linguistic expressions. (Author/RK)

Results of these experiments indicate that the ability to deal with positive and negative instances is not only contingent upon developmental level, but also upon the dimensional characteristics of the stimuli. (Author)

Emphasizes the importance of spontaneous play for growth in cognition and social values. The author specifically discusses finger painting, water, blocks and dramatic play. (AJ)

Paper based on an MS degree submitted by Raymond R. Baird to the University of Washington.

Some of the findings of a longitudinal study of three infants between their 11th and 22nd months to document development of linguistic expression of the agent concept indicated that first vocalizations were inconsistently associated with nonverbal agentive behaviors and later mature utterances coded agent-action-recipient events. (MC)

Discusses the RADAR technique--Read, Analogize, Discuss, Apply, Review/Research--and how it can be used in content area classrooms to teach concepts. (FL)

Examines the development of infants' ability to begin recognizing novel referents of common object names. In particular, the present experiment investigated the development of 12- to 20-month-old infants' ability to infer that an unfamiliar but categorically related object can be designated by a newly learned name for the object class. (Author/RH)

Data on the conservation of discontinuous quantity are analyzed according to two different criteria: judgment only and judgment plus explanation. The results are discussed in terms of Piagetian theory and particularly of the assumption that language development is a consequence, and not a cause, of cognitive development. (Author/KC)

Examines language effects in class-inclusion performance with 224 children ages 3 through 12 by comparing the standard Piagetian question with two alternate question forms. Overall, the findings were inconsistent with the Piagetian assertion that logical inability produces errors in comparing subclasses; inclusion performance was a function of…
