Development of reasoning is often depicted as involving increasing use of relational similarities and decreasing use of perceptual similarities ("the perceptual-to-relational shift"). We argue that this shift is a special case of a broader developmental trend: increasing sensitivity to the predictive accuracy of different similarity types. To test…

Proposes a variant of mental model theory which suggests that the development of conditional reasoning (if--then) can be explained by such factors as the capacity of working memory, range of knowledge available to a reasoner, and his/her ability to access this knowledge "on-line." Finds much empirical data explained by this model.…

Studied high school and university students' use of mental representations in reasoning, and the developmental progression of their reasoning with concrete and abstract content. Reasoning was more difficult with abstract content. Abstract problems followed by concrete ones led to reduced concrete problem performance for high schoolers but not for…

Accent on Developing Abstract Processes of Thought (ADAPT) is a program designed to promote critical thinking among college students. Based on the theoretical work of Jean Piaget, it attempts to help University of Nebraska freshmen confront problems and follow them through to logical solutions. In its first year, the program's goals were to…

The educational implications of Piaget's concept of intelligence provide a framework for the application of theory to educational practice. The uniqueness of individual learning is compared to stage-based teaching. Social interaction is viewed as one of the major forces in cognitive development. (JN)

This booklet introduces elementary school teachers to the methodology, climate, aims, and objectives necessary for the teaching of philosophical thinking to grade schoolers. The methodology casts the teacher as a facilitator whose primary task is stimulating children to reason about their own problems. The discussion process with hints and guides…

"Harry Stottlemeier's Discovery" is the student book for the project in philosophical thinking described in SO 008 123-126. It offers a model of dialogue -- both of children with one another and of children with adults. The story is set among a classroom of children who begin to understand the basics of logical reasoning when Harry, who…
