Two responses to a prior report on significant figures and a discussion on outlining conventions for the accuracy of answers are included in this document. A clarification of the supposed error in the original report is noted at the beginning. (MP)

Highlighted are characteristics of programs written for a pocket-sized programmable calculator to analyze mass spectra data (such as displaying high resolution masses for formulas, predicting whether formulas are stable molecules or molecular ions, determining formulas by isotopic abundance measurement) in a laboratory or classroom. (CS)

Directions for making a device that parents can use to help children practice basic skills are given. (MK)

Changes in the elementary and junior high school mathematics curriculum that have occurred in the last 20 years and that may occur in the future are discussed. (MK)

This essay discusses the possible types of uses of calculators in the elementary school, citing several publications, articles, and research studies. (MP)

This calculator experiment for seventh-grade students on prime factorization contains objectives, difficulties, a discussion, several examples, and a worksheet. (MP)

Two units of study are given here for teaching elementary school students the use of the programable calculator. Storage registers and the program memory are considered. (MP)

Describes a classroom activity designed to give students hands-on experience using technology and geometric visualization, as well as to explore fractal geometry in a cooperative classroom environment. Natural phenomena is the context of these activities. Enriches understanding of Euclidean geometry and infinite sequences. Lists materials,…

Describes the study of a physics teacher whose teaching changed as his beliefs about mathematics changed. Following a week-long institute on using graphing calculators, the teacher became an advocate of calculator use and his algebraic thinking progressed as he realized the importance of functions. (DDR)

Presents a workshop on graphing technology that targeted a diverse group of students from elementary and secondary grades. Includes an activity on exploring the relative rates of heating and sections on reading the graphs, practicing with sensors, and plotting 3-D graphs. (YDS)

Describes the successful use of a computer algebra system (CAS) with a student as he worked on a problem involving functions far more difficult than he had previously encountered. (Author/NB)

Guides students through the process of designing a window. Allows them to use technology and a variety of representations while maximizing and minimizing the dimensions based on cost and light. Includes activity sheets. (Author/NB)

Investigates gender-related effects on the Western Australian Calculus Tertiary Entrance Examinations for the period 1995-2000, three years before and three years after graphics calculators were introduced. Considers students' total examination scores, scores on questions grouped by curriculum components, and students' use of graphics calculators…

A 2-year project helped Supai Middle Schools (grades 7-8; enrollment 600) in Scottsdale, Arizona, explore ways to use calculators as tools for learning and teaching mathematics. This project and other research indicate that students at every grade level can use calculators in classes to understand mathematical concepts. (MLF)

This paper discusses the "Curriculum and Evaluation Standards" (produced by the National Council of Teachers of Mathematics) that are of particular relevance to mildly handicapped children. Concepts discussed include curriculum and instruction, need for a broad spectrum of mathematics, problem solving, vocabulary, emphasis on understanding, and…
