Suggests that problem-solving extensions are appropriate experiences for differentiating learning experiences for students with high abilities. The extensions fall into four major categories: pattern and generalization, new concepts and vocabulary, creativity, and making value judgments. (PK)

This annotated bibliography contains 12 references on computers in elementary school mathematics. Topics include developing mathematical concepts with microcomputer activities, teaching mathematics with computers in primary grades, microcomputers and problem solving, review for grade 1 software, early learning of logic and geometry using…

The undergraduate curriculum in differential equations has undergone important changes in favor of the visual and numerical aspects of the course primarily because of recent technological advances. Yet, research findings that have analyzed students' thinking and understanding in a reformed setting are still lacking. This paper discusses an ongoing…

This study examined the effectiveness of a conceptual change teaching strategy over the traditional method on high school students' (N=152) attitudes towards learning biology. The study employed a two-group experimental control design. The experimental group was taught using a conceptual change teaching strategy. A 21-item instrument that is…

This book contains questions for secondary school science students that require them to analyze data presented in various forms and apply knowledge and skills developed in novel situations. The content for the questions is derived from a science curriculum developed by a group of Caribbean nations. The material is organized into four sections: (1)…

This book explores concept-based learning across disciplines and grade levels. Teachers can use the specific strategies to create a seamless learning program that teaches students the skills they need to think conceptually and to solve problems in today's complex, changing world. Chapter 1 reviews national, state, and local standards through a set…

Examines five general issues related to research on children's use of hypotheses during problem solving: (1) types of hypotheses and how they are detected, (2) the acquisition of hypotheses through cognitive or conditioning mechanisms, (3) learning, sampling assumptions, and rule-guided behavior, (4) feedback variables, and (5) subject variables.…

It was concluded that repeated review is more beneficial to deaf than to hearing students, and that it selectively affects memory tasks (recall and recognition) more than tasks requiring higher level processing (concept acquisition and problem solving). (Author/DLS)

An attempt is made to establish a link between ordinary arithmetical situations and relevant mathematical concepts by the analyzing of complexity of concepts. (MP)

Children who come to school without numerical game-playing experience have trouble with math relationships in direct-instruction situations. This article explores the varied roles of active thinking, social interaction, previous knowledge, and child-initiated choice in children's development of math concepts. Self-esteem cannot be built by doing…

Describes an extended investigation of polygons and polyhedra which was conducted in response to a challenge posed in Focus, a newsletter from the Mathematical Association of America (MAA). Students were challenged to construct a polyhedron with faces that measure more than 13 inches to a side. Outlines the process, including the questions posed…

Identifies and describes the differences in the problem-solving methods used by faculty teaching introductory chemistry and students enrolled in an introductory chemistry course. Results indicate that students correctly solve algorithmic-mode problems more frequently. Contains 33 references. (DDR)

Examines the impact of one unit of a curriculum module for sixth grade from the Model-based Analysis and Reasoning in Science (MARS) project. Provides an overview of this unit on mass and discusses three aspects of the evaluation of the unit. Contains 22 references. (DDR)

Describes a study of third-grade students (N=38) that investigates the development of linear measurement concepts. Three levels of strategies were identified: visual guessing, hash marks, and no physical partitioning. Students who connected numeric and spatial representations proved to be the better problem solvers. Contains 22 reference. (DDR)
