Even though engineering outreach to K-12 schools initially seemed to be a simple undertaking, it proved to require complex design solutions related to a variety of issues. The purpose of this design case is to tell the story of our National Science Foundation (NSF) supported engineering outreach project, that took place between the years of…

Although most calculus students are comfortable with the Cartesian equations of curves and surfaces, they struggle with the concept of parameters. A multivariable calculus course is really the time to nail this concept down, once and for all, since it provides an easy way to represent many beautiful and useful surfaces, and graph them using a…

This article describes a cooperative project between eighth graders and first graders called "Going Green in the Neighborhood." The project entailed the first grade students sketching home designs on paper to make a model community, and the eighth grade students taking those drawings and making them into 3D computer models and then…

This study examines how students in the early stages of learning about the concept of functions, describe a curve and, in particular, evaluate the appropriateness of their argument about the representation of a function. Students are offered a message game which is related to a curve drawn on a coordinate system, representing an "imaginary…

Using Excel, an interactive program is designed to simulate the Solow and endogenous growth models to facilitate the understanding of these models for students of growth theory and macroeconomics.

Discusses educational programs carried out by a minimum system which consists of a PDP-8/L computer with 4K memory and an ASR-33 teletype. Indicates that an entire curriculum with 450 students can be handled by simply adding some components. (CC)

It is felt that all the basic programing concepts can be taught by giving students experience with graphics. Students are viewed to be working on problems that truly interest them, rather than on the standard fare presented in most courses. A description of a class and a graphing program are included. (MP)

This document consists of nine issues of the National LOGO Exchange Newsletter (NLX). Each issue contains several articles as well as regular features and departments. The lead articles in this volume are entitled: (1) "Twenty Powerful Ideas" (Molly Watt); (2) "Multiple Turtles without Sprites" (James Hurley); (3)…

Engineering design graphics education has come a long way in the past two decades. The emergence of solid geometric modeling technology has become the focal point for the graphical development of engineering design ideas. The main attraction of this 3-D modeling approach is the downstream application of the data base to analysis and…

This document consists of 27 issues of the National LOGO Exchange Newsletter (NLX) together with cumulative indexes which provide five access points to information in the newsletters: (1) an author index; (2) a book review index; (3) a product and information index; (4) a column index; and (5) a subject index. The alphabetical author index lists…

This document contains 25 presentations on five broad topics: the interface of computers with instruction; computer applications; computer graphics; computer programming; and general interest sessions. A foreword by Dr. Valeria Amburgey of Sam Houston State University precedes the following papers: (1) "Fourth and Fifth Grade Computer Centers…

This paper describes GUIDON-WATCH, a graphic interface that uses multiple windows and a mouse to allow a student to browse a knowledge base and view reasoning processes during diagnostic problem solving. The GUIDON project at Stanford University is investigating how knowledge-based systems can provide the basis for teaching programs, and this…

Trends in the use of visualization (computer graphics) for instructional purposes are analyzed in three segments: (1) current classroom activities; (2) technically possible but not prevalent classroom activities; and (3) the future classroom. The discussion draws on University of Iowa efforts, national curricular innovations, and presentations and…

Many organizations and experts in the field of mathematics education have recommended the inclusion of technology and, more specifically, computer programing within the course of study for the teaching of school mathematics. The incorporation of these recommendations with respect to the teaching of remedial mathematics poses a problem, since…
