This study, conducted in one high-achieving secondary school in a disadvantaged area in the Western Cape province of South Africa, asks whether mathematics teachers alter their "talk" across the face-to-face and computer-based lessons. Data were gathered through video recordings of teacher/student interactions across ten face-to-face and…

The purpose of this research study was to understand how mathematics majors make sense of similar matrices, a linear algebra topic that is rich in internal and external connections, in a series of in-depth qualitative interviews in a technology-assisted (MATLAB) learning environment. The study was also an attempt to develop a cognitive theory in…

This article is written to share teaching ideas about using commonly available computer applications--a spreadsheet, "The Geometer's Sketchpad", and "Wolfram Alpha"--to explore three classic and historically significant problems from the probability theory. These ideas stem from the authors' work with prospective economists,…

This article was motivated by the authors' work on a project with a group of 2nd-grade students in a computer lab of a rural school in upstate New York. From this project, one goal of which was to provide a capstone experience for a teacher candidate in teaching application-oriented mathematics with technology, the ideas about parallel structures…

The overarching goal of this four-phase, in-service project--Girls Engaged in Mathematics and Science--was to change attitudes, behavior, pedagogy, and curriculum for girls through the provision of a vibrant, engaging, digital portal program with media that extends learning beyond the traditional classroom. Described here, Phases I and II were…

Technology-enhanced mathematics tasks were introduced to elementary pre-service candidates (n = 84) and in-service teachers (n = 38), who then, either in partners or small groups, created and taught inquiry-based lessons incorporating technology, with individual reflections. The lessons were coded using the following criteria: (a) The students…

Discusses the connection between mathematics and the computer; mathematics curriculum; mathematics instruction, including teachers learning to use computers; and the impact of the computer on learning mathematics. (LRW)

Discusses ways in which technology is changing mathematics education. Highlights include guidelines for appropriate technology use in the mathematics classroom; the impact of computers on mathematics learning; common uses of computers in mathematics education, including software, the Internet, and programming; and issues and concerns related to…

Briefly examines the components of mathematical problem solving instruction, suggests seven guidelines for computer assisted instruction software in mathematical problem solving, and examines three commercially available examples of such software. (MBR)

Illustrates the diverse ways in which the computer spreadsheet can be used by both teachers and students as a problem-solving tool in high school mathematics, and provides detailed examples of spreadsheet use in word problems. Discusses the functions of spreadsheet tables, columns, and graphs. (AEF)

Five articles describe improvements in instructional software designed to enhance problem solving skills. Issues addressed include problem solving software to implement curriculum goals; problem solving theory and writing theory; software for elementary and secondary school science instruction; software for mathematics instruction; and cognitive…

Describes three integrated development cycles for a series of software packages for teaching mathematics: (1) development of a software package, including rationale and didactics; (2) cognitive studies leading to a more effective interaction between student, software, and teacher; and (3) organization of pedagogical knowledge for software…

Illustrates the importance of helping students explore and discover topics in geometry and shows how students who use Geometer's Sketchpad, a powerful computer drawing program, develop a better understanding of geometry. Describes several activities that use the technology to help students discover a wide range of geometric relationships. (AEF)

Discussion of Logo use to teach children computer programing covers the educational theory behind Logo, how it differs from other programing languages, its educational promise, its graphics capabilities, Logo research, and different versions available. It is argued that educational computing will succeed only if it provides new ways of teaching.…

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…
