Reports a study to investigate the extent to which research experience of designing and conducting their own study could enhance five preservice teachers' understanding of children's knowledge of the mathematical concept of fractions. Results indicated that research experience is fruitful in developing an inquisitive disposition in preservice…

Describes activities and resources for elementary and junior high school students that highlight the contributions of African-Americans in the United States. Materials reviewed include games, workbooks, teacher's guides, and books for students. A list of distributors who can provide additional print and nonprint materials is included. (two…

Described is a course designed to teach students about fractals using various teaching methods including the computer. Discussed are why the course drew students, prerequisites, clientele, textbook, grading, computer usage, and the syllabus. (KR)

Presented are exercises that demonstrate the application of standard concepts in the design of algorithms for plotting certain fractals. The exercises can be used in any course that explains the concepts of bounded or unbounded planar sets and may serve as an application in a course on complex analysis. (KR)

Provided are student activities to introduce the geometric concepts of line symmetry and rotational symmetry as related to Hawaiian quilting patterns. Paper squares, scissors, and folding techniques afford the teacher the chance to stimulate class discussion about pattern recognition and to integrate mathematics with the cultural world outside the…

Explains 2 decision-making problems presented to 188 undergraduates enrolled in introductory psychology classes to teach the principles governing individual and collective decisions. Shows individual interest outweighed mutual benefit. Promotes active learning about psychology and scientific skills while stimulating personal development (CH)

Presents the template method developed by Galileo for calculating areas of geometric shapes constructed of uniform density and thickness. The method compares the weight of a shape of known area to the weight of a shape of unknown area. Applies this hands-on method to problems involving calculus, Pythagorean's theorem, and cycloids. (MDH)

Describes and evaluates the format and grading procedure of an Environmental Agronomy course offered at Colorado State University. Teaching methods include videotape use, field trips, and lectures addressing topics such as integrated pest management, land application of sewage sludge, pesticide degradation, and organic farming. Standard course…

Discusses books and films that have themes relating to water that are suitable for elementary school children and suggests activities that can be used to complement them, including writing and designing exhibits. Materials from various cultural backgrounds are suggested, and a list of 62 books and 5 films is provided. (LRW)

Interprets and contrasts children's mathematical interaction from the points of view of radical constructivism and of Soviet activity theory. Proposes a superseding model based on the interrelations between the basic sequence of actions and perturbation and the interaction of constructs. Supports the model by describing how children used…

Proposes a new model of children's mathematics by composing aspects of the Fraction Project and critiques presented in the same issue. Argues that computer microworlds provide children with dynamic learning environments in which they are the primary actors and teachers with a medium for interact with children's mathematics while trying to maintain…

Describes a project for first and second graders involving gathering and interpreting survey data from another student they have never met to identify the student at the end of the project. Includes sample curricular goals and instructional strategies. (MKR)

Describes a preschool curriculum unit that includes activities designed to help prepare young children for medical treatment, visits to hospitals, and health care. (BB)

Presented are four activities which allow students to work with rhombus patterns. These activities encourage students to search for, test, and verify patterns and to also practice computation and work with ratios. Diagrams needed for each activity are included. (KR)

This paper offers a longitudinal perspective on early intervention for children with disabilities. The quality of life which results from intervention is discussed, and features of intervention programs, such as early screening, a focus on the family, and classroom processes, are described. (BC)
