Assuming that dynamic features of Dynamic Geometry Software may provide a basic representation of both variation and functional dependency, and taking Vygotskian perspective of semiotic mediation, a teaching experiment has been designed with the aim of introducing pupils to the idea of function. First data coming from the observations in Italian…

Nathan entered third grade having already constructed a Generalized Number Sequence (GNS) for whole numbers that enabled him to coordinate sequences of multiples to find a common multiple of two whole numbers. Nathan was able to apply the operations of his GNS to his understanding of part-whole relations and his emerging use of fractional…

This paper illustrates the themes of reflection and connection in teacher education by discussing the experiences and conceptions of one preservice teacher who was enrolled in a secondary mathematics methods course. Small groups of preservice teachers created hypermedia stacks to demonstrate their views on important issues in mathematics…

Research on the use of computers and other educational technology with young children has become increasingly sophisticated as their use has increased in early childhood educational settings. This paper reviews the research on computers and social interaction, teaching with computers, and curriculum and computers. The review finds that computers…

Examined effects of self-regulatory teaching approach in a computer context on mathematics learning of at-risk preschoolers. Found that computer-based contexts provided at-risk children with an effective context for learning mathematics and that enhancing that context with a self-regulatory teaching emphasis resulted in significantly increased…

This article describes teaching mathematics to students with disabilities using "My Math," a three-component software program consisting of "shells" into which students or teachers insert content. The three components include computation problems, arithmetic word problems, and arithmetic story problems. The content of the program is discussed,…

Discusses uses of the microcomputer in elementary mathematics education. Included are: (1) drill; (2) practice; (3) problem solving; and (4) games. (YP)

Notes muMATH is a powerful computer algebra systems assistant for performing symbol manipulation in algebra and calculus. Provides several examples and program listings for calculus tutoring, differentiation drill problems, and integration drill problems. (MVL)

Discusses four activities focusing on communication about shapes and spatial relationships. The activities include requiring students to sketch patterns, and two-dimensional and three-dimensional visualizations. Provides several figures showing the geometric shapes. (YP)

Provides a short BASIC program, RANVAR, which generates random variates for various theoretical probability distributions. The seven variates include: uniform, exponential, normal, binomial, Poisson, Pascal, and triangular. (MVL)

Two incidents involving novice teachers with classes in grades 7 and 10 are presented. Then considered are the nature of intuitive mathematics and contributions computers can make to such intuitive mathematics, particularly in Algebra. (MNS)

Describes the Interactive Mathematics Program (IMP), a four-year program of problem-based mathematics that integrates algebra, geometry, and trigonometry with additional topics, such as probability and statistics, and uses calculator and computer technology to enhance student understanding. (MKR)

Describes and analyzes attitudes of two Portuguese elementary teachers toward mathematics, mathematics teaching, and use of computers in instruction. Semistructured interviews and questionnaires, before and after an inservice LOGO computer course, showed that both teachers changed their attitude, but only one implemented her ideas in teaching. (20…

Examines the use of spreadsheets for solving equations by the method of iterations. The combination of the spreadsheets and graphical representation is shown to be appropriate both for teaching and learning the method of iterations and for investigating properties of equations. (Author)

Examines the use of the computer to approximate the value of the definite integral normally calculated by mathematical means. Presents four examples using BASIC programs to approximate single and double integrals by numerical integration and the Monte Carlo method. Programs are provided. (MDH)
