Having an ability to appreciate, understand, and generate proofs is crucial in being able to evaluate students' mathematical arguments and reasoning. As such, the development of this ability in perspective teachers is imperative. This study examines the work of a group of preservice elementary school teachers in their efforts to generate one-line…

Accelerated Math (AM) math management software is a task level learning information system placed in 4th-11th grade classrooms around the country. AM provides teachers with an information system that assures that students can master all math objectives and state standards from grade 3 through calculus. It eliminates teacher paperwork, improves…

This paper investigates the effects of a computer algebra system (DERIVE) on students' comprehension and computational skills in Brief Calculus, a first course for non-mathematics majors. Research results indicate better conceptual understanding by the group using DERIVE without the loss of pen-and-paper computational ability. (KHR)

Computer-aided software has been used intensively in many mathematics courses, especially in computational subjects, to solve initial value and boundary value problems in Partial Differential Equations (PDE). Many software packages were used in student lab assignments such as FORTRAN, PASCAL, MATLAB, MATHEMATICA, and MAPLE in order to accelerate…

The purpose of the study was to compare two methods of learning multiplication facts in order to develop speed and accuracy. The researcher conducted the action research project with a seventh grade enrichment class, which met for seven weeks during the school year. As part of the curriculum students were provided with activities to refine their…

Focuses on the development of a middle school's meaningful problem-based computer and technology education program. Discusses constructing the bridge between in-school and out-of-school learning by preparing real-life situations in the classroom. Highlights the use of technology, especially computers, by focusing on problem posing and problem…

Discusses several dynamic geometry constructions with rectangles. Advocates use of software like Geometer's Sketchpad and Cabri Geometry for fostering fresh insight into traditional geometric theorems. Illustrates problem-solving methods not possible with pencil and paper. (MTE)

Describes a simple experiment that uses a CCD video camera, a display monitor, and a laser-printed bar pattern to illustrate signal sampling problems that produce aliasing or moiri fringes in images. Uses the Fourier transform to provide an appropriate and elegant means to explain the sampling theorem and the aliasing phenomenon in CCD-based…

Overviews a model built to identify and organize successful use of information and communication technology (ICT) in secondary classrooms to support teaching and learning. Teachers found ICT most effective in facilitating routine components of classroom activity; increasing pupil productivity, confidence, and independence; supporting various…

Investigates the effects of inquiry activities on a dynamic geometry environment designed to confront students with contradictions and uncertainties. Characterizes epistemological, didactic, and cognitive aspects of the activities. Analyzes the interplay among these three aspects, students' investigations, and their explanations. (Author/KHR)

Reports on a study designed to build instructional software to improve estimation, reasoning, and problem solving skills using an animation-based tutor for algebra word problems. Concludes that estimation and the solution of simpler problems (i.e., decomposition) are effective strategies. (Author/MM)

Recounts the experiences of faculty members as they addressed some of the challenges presented in choosing and integrating a new technology, the TI-89 hand-held computer algebra system (CAS), into the core mathematics curriculum. Relates in detail deciding which instrument to choose, instructing students to use the technology, affecting the…

Investigates ways to analyze change in various contexts. Focuses on computer technology providing contexts for children's investigations of patterns of change and helping to develop foundational ideas of algebra and calculus. Discusses relationships between patterns of change, fundamental algebraic notions as linear and nonlinear functions, and…

Reviews research on the appropriateness of computer use with young children. Discusses the effects computer use on children's lives, interaction, social and emotional development, learning and thinking in mathematics, and the implications for teachers. (KHR)

Presents ideas for using a spreadsheet to reinforce teaching of enumerative combinatories in the secondary mathematics classroom. (PR)
