The quadratic function can be modeled in real life by a suspension bridge that supports a uniform weight. This activity uses concrete models and computer generated graphs to discover the mathematical model of the shape of the main cable of a suspension bridge. (MDH)

Discusses the rationale and use of problem fields which are sets of related and/or connected open-ended problem-solving tasks within mathematics instruction. Polygons with matchsticks and the number triangle are two examples of problem fields presented along with variations in conditions that promote other matchstick puzzles. (11 references) (JJK)

Indicates that utilizing calculators to introduce algebraic concepts in a prealgebra course provides students with a solid foundation for the study of college mathematics. Pedagogical criteria emphasized the difference between exact and approximate results, appropriate use of the calculator in problem solving, the role of estimation in…

Concrete experience should be a first step in the development of new abstract concepts and their symbolization. Presents concrete activities based on Hyde and Nelson's work with egg cartons and Steiner's work with money to develop students' understanding of partitive division when using fractions. (MDH)

Presents three stories from mathematics history that can be integrated into classroom teaching: (1) the account of how Eratosthenes measured the circumference of the earth to discuss the concept of units in measurement, (2) ideas from Archimedes, Vite, and Descartes to introduce pi, and (3) the discovery of the Cardanic formula as an example of…

Describes a qualitative study that explores students' perceptions of their own learning. Document review, participant observation, and open-ended interviews were used to gather and triangulate data. Factors that were perceived as helpful were woven into a theoretical model. The uses of the model are discussed. (Author/KR)

Discusses historian Henry Adams' disillusionment with the educational system and with his own teaching. Suggests improving history instruction by involving students more actively in learning. Proposes incorporating interactive learning strategies including (1) interactive lectures; (2) questioning; (3) small groups; (4) critical thinking and…

Discussion of technological innovations in education focuses on the potentials of the microcomputer as a classroom instructional method. Programing, computer literacy, software applications, and problem solving are suggested as ways to incorporate computers into the curriculum, and examples of applications of computers in elementary and secondary…

The "Thinking Actively in a Social Context" (TASC) project, currently underway with African-American high school pupils and teachers in KwaZulu/Natal schools (South Africa), stresses the systematic development of thinking and problem-solving skills. The program has been very successful with relatively high achieving students but requires…

Many early childhood teachers report an increase in children's use of aggressive means to work out disputes, often as a result of such influences as the Teenage Mutant Ninja Turtles fad. This article offers suggestions for helping children learn ways to resolve conflicts and for creating a conflict resolution curriculum. (LB)

Discusses instructional uses for the "Carmen Sandiego" software series to encourage interest in geography. Suggests "Carmen" be incorporated into the curriculum by teacher-directed grouping that adds teacher instruction into cooperative and competitive arenas, curriculum integration linking diverse specialties, and isolated…

Identifies areas of knowledge that differ between successful and at-risk students: sense of self-as-learner, level of understanding of problems in subjects, and ability to interact in relationships. Suggests a hands-on project to develop problem-solving abilities and self-confidence. Discusses objectives for a restructured curriculum. (DK)

Articles in this collection clearly illustrate that the debate over indigenous and Western knowledge confronts the Pacific microstates with polarities that are difficult to resolve. Among them is the colonial heritage of an educational system designed to promote docility. National leaders face hard choices in addressing national goals. (SLD)

This study of third graders examined whether qualitatively distinct cooperative computer environments (using LOGO and curriculum-based instruction in writing) engender social experiences that enhance motivation and self-concepts as learners; and the extent to which differences in motivation and self-perception accounted for differences in…

Discussion of graphing software for educational purposes focuses on a study in which three versions of an original computer graphing program were used by inner-city high school students to solve scientific data analysis problems. Variations in degrees of flexibility and feedback in the software are explored. (Contains 37 references.) (LRW)
