Examines the mathematical process used by students when solving physics tasks that require proportional reasoning. Investigates students' understandings and explanations of their mathematical processes. (Author/CCM)

Investigates whether high school Algebra I students' (n=29) writing about their mathematical problem solving processes showed evidence of a metacognitive framework. Indicates that various metacognitive behaviors were present in students' writings. Describes the more predominant metacognitive behaviors. (Contains 36 references.) (Author/ASK)

termined that students who completed writing assignments on mathematics problems were better problem solvers than students in control groups, supporting the contention that expository writing is an effective, practical, and innovative tool for problem solving. (Sample problems and writing assignments are included.) (DH)

Algebraic and computer solutions are offered for a problem on time payment scheduling. The problem, falling within the scope of high school algebra, could focus only on the algebraic methods, but including the computer brings out the relationship between the power of algebra and the power of modern technology.

Use of calculators for teaching percent to first-year general mathematics students is explained by addressing such areas as sequence of lessons, teaching/learning problems, calculator errors, and recommended instructional strategies. Teaching concepts independent of calculator usage, not using special percentage keys, and initiating estimation as…

This paper reports on the experiences of a small collaborative inquiry group consisting of a high school science teacher, Deidre, and two university researchers, the authors of this paper, as they explored an active, inquiry-based approach to teaching and learning referred to as Problem-Based Learning or PBL (Barrows, 1994; Barrows & Tamblyn,…

Describes the Secant Method, a numerical method to approximate solutions to equations for which symbolic solution methods do not apply. Illustrates the method using the EXCEL spreadsheet program. Discusses instructional implications of utilizing this method. (MDH)

Discusses how nonparametric statistical procedures can be applied to the scoring of cross-country running races. Asserts that this type of example in statistics is appropriate for the upper-secondary school and lower-division college levels. (MDH)
