Describes how using spreadsheets helped seventh grade algebra students develop problem-solving skills. Topics include the functional dualism of the spreadsheet as a text, uniting enactive and numeric modeling of word problems, new meanings and reciprocal learning, learning through problem "posing," higher levels of thinking, and decreasing…

Investigated the ways teachers' content knowledge affected implementation of mathematics education reform by observing teachers during a reform-based algebra lesson. Found that teachers learned during this process by modifying existing content knowledge and developing new content knowledge and appropriate strategies, and that teachers negotiated…

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)

Reviewed are two computer software packages for Macintosh microcomputers including "Phase Portraits," an exploratory graphics tool for studying first-order planar systems; and "MacMath," a set of programs for exploring differential equations, linear algebra, and other mathematical topics. Features, ease of use, cost, availability, and hardware…

Describes the results of three years of field-work and the prospects for change in algebra teaching as a consequence of using computers and calculators. Summarizes the structure of text materials, classroom organization, and students' responsibilities. (YP)

Describes PRECEPTOR, an intelligent tutoring system that provides multiple explanations for algebraic word problems involving two variables. Modeling the cognitive processes of an effective teacher is discussed, the capacity for individualized tutoring is examined, and differential tutoring based on varying difficulty levels is explained. (17…

Reviews six research articles involving the use of computers for mathematics instruction: (1) geometry skills; (2) calculus; (3) interactive videodisc in pre-calculus; (4) model for integrating computers in classroom; (5) computerized tutoring in applied algebra; and (6) software for enhancing problem-solving skills. (YP)

Discussed are assumptions about technology and classroom equipment, teaching methods, getting started, pitfalls, and the role of algebra and calculus. Suggestions are given for implementing the spirit and vision of the standards. (YP)

Illustrated is the problem of solving equations and some different strategies students might employ when using available technology. Gives illustrations for: exact solutions, approximate solutions, and approximate solutions which are graphically generated. (RT)

Presented are problem-solving experiences with area, volume, and algebraic expresssions resulting from data collection. Three worksheets are included for students in grades 7-12. (MNS)

Presents a selection of solutions of the "Three Hungry Men" problem from grade three to college students with three different strategies used: backward, forward, and forward/backward strategies. Provides error patterns in each strategy. Discusses some implications for teaching of problem solving. (YP)

Middle-school students were asked to determine the dimensions of a hotel atrium so that guests could enjoy the maximum area of scenic view, given that 650 feet of brass railing could be used around each floor. Several solution approaches are described. (MKR)

Tests of (n=105) ninth-grade algebra students involving the addition and multiplication of monomials found that common, systematic errors made when multiplying monomials were related logically to the symbolism used and the algebraic convention of using an implicit 1 as an exponent. (16 references) (MKR)

Surveys of mathematics department chairpersons about changes in algebra instructional practices in response to the National Council of Teachers of Mathematics' Curriculum and Evaluation Standards showed wide variation across schools. Contains survey questions on practices in algebra and a bibliography of first-year algebra textbooks. (12…

Presents suggestions for developing algebraic concepts beginning in the early grades to develop a gradual building from informal to formal algebraic concepts that progresses over the K-12 curriculum. Includes suggestions for representing relationships, solving equations, employing meaningful applications of algebra, and using of technology. (MDH)
