This paper describes two experiments in which children in grades 1, 3, and 5 were given three kinds of spatial perspective-taking problems to solve as quickly as they could: (1) C problems, solvable only by computation (that is, noting which features of a particular object array were closest to another observer in order to estimate how the array…

Experiments are reported in which semantically interrelating sentences were presented to subjects as discrete items, and inference tests were given to measure the degree to which the similar information had been stored in the same memory system. Results suggest that verbal information is sometimes encoded into an episodic system. (Author/RM)

Distortions in judgments of relative geographical relations were observed, particularly when the locations were in different geographical or political units. Subjects distorted the judged relation to conform with the relation of the superordinate political unit. A model for the hierachical storage of spatial information is presented. (Author/RD)

Investigates whether the formal schemata and propositional logic are acquired gradually across age during adolescence, in agreement with Piaget's logical analysis of the structure of formal thought, or acquired in wholesale spurts, thus disagreeing with Piaget's theory. (GA)

The impact of language (especially written language) on the acquisition of knowledge and skills in children is discussed. (MJB)

Tests indicate that females have innately less ability to perceive spatial relationships than males, but that proper training can improve spatial performance and reduce this natural disparity. (JD)

Presentation of a "natural experiment" problem situation to fourth, sixth, and eighth graders and college students revealed that not until adolescence could subjects isolate alternative or additive causes in a multivariable situation. (JMB)

Holds that ethical inquiry, as a "craft," causes students in this area to be "apprentices," and the classroom a "community of inquiry" wherein the tools, methods, practices, and procedures of the craft are imparted. States that the generic procedures of reasoning, necessary for moral reasoning, should be taught within…

Addresses the question: If an intellectual change is truly fundamental, how can it be socially comprehensible? Claims that the question is particularly pressing in the case of Darwin's "Origin." Argues that the answer lies in an understanding of how scientific revolutions depend on continuity with an existent cultural grammar. (JD)

Shows that sixth-grade students did not use as much oral language for forecasting and reasoning as did third-grade students or students in kindergarten when their language was recorded under similar conditions. Suggests that perhaps the very process of schooling inhibits students' need to think creatively and to reason. (FL)

Two studies examined the relation between current developmental levels, as estimated by IQ, and proximal levels of development, as estimated by the efficiency of learning and transfer in assisted contexts. Subjects were 8- to ll-year-old children. Theoretical and clinical implications are discussed. (HOD)

The research and development of mental (standardized) testing and its relationship to educational practice is traced historically from its pre-World War I roots to its controversial national prominence in the 1970s. How standardized tests have been used in research and in schools is analyzed. (BS)

Four experiments are presented to support the theory that the rule system governing the law of large numbers is not tied to a content domain, and that it can be improved by formal teaching techniques. The experiments showed that statistical training enhanced everyday reasoning. Test problems and objective example problems are appended. (LMO)

Examines why analytical thinking should be a major focus of teaching in the reading and writing classroom. (HOD)

Provides guidelines for conducting and interpreting interviews aimed at assessing the cognitive concepts of young children. Discusses the content, task, questions, and format of the interview, listing 16 points of advice for interviewers. Also elaborates on the value and use of structured interviews. (JM)
