Describes software tools designed to help students investigate relationships among representations of rational numbers that emphasize the part-whole model of a rational number. (KHR)

Provides an annotated bibliography of nine current articles from the ERIC database on using computers as instructional tools. Includes articles related to computer uses in reading and writing classes; for spelling improvement; to accommodate learning disabled students; and for speech, sign, or foreign-language courses. (AJL)

Presents an interdisciplinary project for precalculus classes that allows students to increase their understanding of the mathematics of transformations of periodic functions and helps them see mathematics in art. Uses an applet that produces high-quality graphs and real works of art by using combinations of transformations of the sine and cosine…

Provides practical ideas for "raising the bar" on student, technology-rich projects as teachers and learners work together to transform the learning environment. Explores levels of complexity in student products and determines what is realistic in terms of matching standards and activities with time and resources. (Author/AEF)

Discusses the development, implementation, and evaluation of a unit designed to assist preservice teachers of quantitative literacy called numeracy. Investigates the relevance of quantitative literacy to daily life, aspects of quantitative literacy, and lessons in schooling using an internet site as a teaching resource. (Author/KHR)

An instructional package, LD.Trainer, was developed from a computer-based expert system (CLASS.LD2) combined with strategies of effective concept instruction. Evaluation with 97 preservice and in-service educators found users of LD.Trainer scored significantly higher on a posttest of ability to accurately identify learning-disabled students. (DB)

This article proposes a model for a supported, managed effort to create an environment in which faculty can successfully integrate technology into the teaching process. The model is based on needs identified by the information services organization at West Chester University. An alternative financial model is offered. (Author/MLW)

Uses an asynchronous computer network to conduct an experimental college writing class. Examines how paperless technology alters student-mentor relationships and encourages coaching and practice more than conventional classrooms. Analyzes how on-screen equality influences teacher and peer evaluations of student writing. Includes breakdown of time…

Discussed is four years of intensive experiences of working with preservice secondary mathematics teachers in helping them to integrate computers into their mathematics instruction. Student experiences in the classroom and in field experiences, and changes in student attitudes and beliefs toward computers and mathematics are described. (CW)

Described is a series of computer tutorials developed to teach students a logical method of problem solving for chemistry. The structure, pedagogy, and problem-solving strategies of the computer software program are described. (CW)

Presented is a simple laboratory set-up for teaching microprocessor-controlled data acquisition as a part of an instrumental analysis course. Discussed are the experimental set-up, experimental procedures, and technical considerations for this technique. (CW)

Illustrates how muMATH can be used for manipulating abstract differentiation rules, optimization, implicit differentiation, related rules, and verifying the chain rule. (MVL)

Lists a BASIC program which computes the equilibrium constant as a function of temperature. Suggests use by undergraduates taking a one-year calculus-based physical chemistry course. Notes the program provides for up to four species, typically two reactants and two products. (MVL)

A Kentucky kindergarten teacher describes the conceptualization, planning, and implementation of a writing program she designed for her students. She discusses the impact of writing activities on reading, phonics, and spelling development. Included are samples of pupil writing and an explanatory letter to parents explaining the program. (IAH)

Stresses that not enough attention has been given to the need to teach computer skills to school administrators. Lists five basic competencies for a computer literate school administrator. Suggests 12 topics to be taught in the administrator course. (MVL)
