The exploration, discovery, and generation of attractive two-dimensional designs as an approach to informal geometry and spatial learning is discussed. Six activities with brief instructions are presented. (CW)

Discussed is the case for problem solving in mathematics classrooms. The characteristics of "good" questions are identified. The assessment of questions and questioning techniques is considered. (CW)

Argues that the basis for communications between teachers and between teacher and student lies in the beliefs that teachers hold about mathematics and problem solving. Proposes a framework for teacher education curricula that describes seven dimensions on which primary mathematics education can be developed. (MDH)

Proposes the utilization of graph theory to solve optimization problems. Defines the notion of spanning trees and presents two algorithms to determine optimization of a spanning tree. Discusses an example to connect towns by power transmission lines at minimum cost. (MDH)

Presented are the results from a few of the writing prompts used in a study and some of the comments made by individual students in response to specific prompts. Background of the study, an intervention strategy, and categories used (prompts, responses, applications, and explanations to peers) are discussed. (CW)

Presented is a short mathematical appraisal of some liquid measurements that are encountered by students in everyday life. Discussed are volumes of containers, container construction, and container calibration. (CW)

Discussed are student mathematical background, computing skills, and case studies/field studies as they relate to business studies. A list of basic skills for tertiary business studies is provided including sigma notation, basic algebra, change, and solving equations. (CW)

The purpose of this article is to highlight and discuss the role of language as the link between experiences with number patterns and the emergence of algebraic notation. Discussed is a recommended approach. A sample of a written student response is provided. (CW)

Described is a study designed to extend a theoretical model of children's progression from a perceptual to an abstract concept of number. The implications of this research for the design of mathematics curricula are discussed. (CW)

The experience of several different female mathematicians in the male domain of mathematics is discussed. The implications of the barriers experienced by these mathematicians for girls in mathematics are discussed. (CW)

Presents an approach to teaching statistical ideas, including describing distributions of scores, location of the center, and the spread of a distribution (dispersion). (MKR)

Discusses a method of examining student expository writing that can be used by teachers to evaluate students qualitatively. (MKR)
