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,…

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],…

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)

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

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)

Some of the literature related to preschool mathematical experiences and their effect on the development of how the child perceives the relationships of mathematics is reviewed. (MP)

Presents an approach to quadratic functions that draws upon knowledge of linear functions by looking at the product of two linear functions. Then considers the quadratic function as the sum of three monomials. Potential advantages of each approach are discussed. (Contains 17 references.) (MDH)

Evaluates the CHEM study topics of kinetic theory of gases, phase changes, chemical bonds, and equilibrium as to the level of cognitive development required for an understanding of each subject. Advocates an assignment of topics within the range of a student's cognitive ability in an individual study format of instruction. (CP)

Advance organizers may fail to promote learning even though they are approximately related to the main learning experience and internally meaningful and logical. If they are to optimize the likelihood that new materials will be readily and properly subsumed, they must also be constructed to conform to the cognitive preparedness and scholastic…

A presentation of learning experiences involving materials is recommended which reflects the sequence of the developmental stages. This sequence is concrete, concrete-abstract, pictorial-abstract, and abstract. Instructional examples at each level are presented. (JP)
