In his last book, "Toward a Logic of Meanings" (Piaget & Garcia, 1991), Jean Piaget describes how thought can be categorized into a form of propositional logic, a logic of meanings. The intent of this article is to offer this analysis by Piaget as a means to understand the language and teaching of science. Using binary propositions, conjunctions,…

The performance of elementary school children on tasks requiring right and left hemisphere function was investigated and asymmetries in hemisphere function were discovered. (MP)

Described are ways in which curriculum in science and mathematics may be shaped to the adolescent. Several examples relate to cognitive development, neurological functioning, physical changes, social evolution, and moral growth of the adolescent. (DS)

Mathematics and science are important for success in school, but learning mathematics and science can be a difficult task to some students. Efforts to improve students' learning of school mathematics and science have led to reform efforts in curriculum and instruction over the past decades (e.g., National Council of Teachers of Mathematics [NCTM],…

Investigated was whether reading achievement could be increased by exposure to logical and perceptual tasks as found in science process activities. (MP)

Reported is a study involving six group administered tasks concerning proportional, probablistic, and correlational reasoning with 505 students aged 11.5 to 20.0 years. Investigated were the effectiveness of the tasks for assessing formal reasoning; categories of classification for students' responses and implications for teaching are suggested by…

This article supports the learning theory and intellectual development model of Jean Piaget as a theory base for science education. (Author/MK)

Describes three perspectives from which middle school teachers can plan laboratory activities for the purpose of improving students' scientific literacy. Perspectives are the learning cycle approach categorizing activities by stages of development; problem-solving skills approach categorizing activities according to the amount of teacher control;…

Examines the feasibility of including instruction in common schemes of inference in the elementary grades. (CP)

The relationship between a student's stated preference for solving a problem and his/her actual problem methodology, concrete or abstract, was studied. Comparisons were made between formal and nonformal students. (MP)

Examples from some area tasks indicate that misconceptions about linear measurement can be carried over to area measurement; children will occasionally count points rather than length units or area units. (MP)

Discusses the nature of technological literacy, considering its relationship to science education, mathematics education, and computer science education. Indicates that technological literacy is a skill and an attitude which is basic to contemporary society. Problems related to cognitive development are noted. (JN)

First and second graders' understanding of transitivity for each of the relations "larger than,""smaller than,""longer than," and "shorter than" was investigated. Results showed that on only two of the eight comparisons did the order of presentation of the premises make a significant difference in students'…

Investigates the effectiveness of utilizing analogies to effect conceptual change in students' alternative-probability concepts. Results indicate that analogies can be effective in producing desired conceptual change in high school students' probability concepts. (Author/CCM)
