Discusses briefly Piaget's views on intellectual development as related to science teaching. Describes intellectual activities observed in science classrooms and shows how specific science lessons can be designed to encourage cognitive development. (GA)

Investigated the relationship between syntactical complexity of high school students' written language and their ability to reason formally. Format reasoning ability of 50 high school students was measured by a 15-item group-administered demonstration test developed by Lawson. (HM)

Language disorders in mentally retarded children may be assessed by standardized tests, developmental scales, and informal procedures. The processes to be assessed include comprehension, production, and use in communication. In the assessment of a child, these processes should be related to chronological age and to cognitive development. (CTM)

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)

Presents a classroom activity which can be used both to assess student's modes of thought and to clarify the logic of hypothesis testing. The task is based on Piaget's theories of cognitive development. (HM)

The College for Living is an educational program for adults with developmental disabilities. It is based on the theory that everyone can learn something and has the right to an education in a positive setting. The program is characterized by high morale, nontraditional teaching methods emphasizing experiential learning, and individualization.…

Primary school children at different stages of acquisition of conservation pretended that their judgments on a series of conservation problems were the opposite of their actual beliefs. The nonconservers and transitional conservers made significant gains in conservation, while the conservers did not regress. Cognitive dissonance training is…

Fourth-grade control students were given a multiple-choice problem involving conservation of weight. Experimental group subjects were given a fictitious choice response distribution with conflicting reasons. Curiosity for confirmation, progress in generalizing the principle of conservation, and positive correlation between curiosity and progress…

Six-and eight-year olds were exposed to a modeling sequence for cluster rule learning under high, medium, and low degrees of structure. Age differences in vicarious learning emerged only in the medium structure condition, while immediately imitating a model failed to influence learning for either age group. (Author/CP)

This replication study negates Bruner's finding that older subjects (age 15 and adult) understand the mathematical concept of ratio as exemplified by comparing judgments of fullness in pairs of glasses differing in height, diameter, and water volume. Weaknesses in Bruner's design and procedure that explain the discrepancy between the two studies…

Describes procedures used to measure students' cognitive learning in an American government course. The procedures combined evaluation of instructor effectiveness, teaching efficiency, student learning, and student demographic characteristics. (AV)

This cardiovascular fitness program for grades 1-6 (with emphasis on grades 5 and 6) consists of (1) discussion classes and exercise experiments, (2) discussion of exercise effects during regular activity sessions, (3) required cardiovascular warmup exercises, and (4) evaluation of cardiovascular fitness. (Author/MJB)

Reports a study of 99 twelfth graders to determine the nature and extent of misconceptions in chemical equilibirum and its relationship to achievement on tasks involving concrete and formal thought. Results indicate assessment of the student's cognitive level of development should be attempted prior to introducing formal level chemical…

Proposes a model for cognitive development and the development of self efficacy in infancy. Examines the effects of two intervention programs in which caregiver responsiveness and amount of stimulation are varied. Subjects were 100 nine-month-old infants from working class families. (BD)

Here are some ideas that the nursery-school teacher might suggest to parents as ways to set the stage for learning in mathematics for their children. (MN)
