A multiple baseline design investigated the effects of computer graphic organizers on the persuasive composition writing skills of four Hispanic students with specific learning disabilities. Participants reviewed the elements of persuasive writing and then developed compositions using a word processing program. Baseline planning was done with a…

Computer Algebra Systems (CAS) are equipped with rich facilities to show graphics, so the use of CAS to show 3D-graphics on screen is a popular tool for mathematics education. However, showing 3D-graphics in mass printed materials is a different story, since the clarity and preciseness of figures tend to be lost. To fill this gap, we developed…

Describes a rapid computer technique for plotting Eh-pH diagrams using a line printer. (MLH)

Described is an inexpensive apparatus, consisting of a microcomputer, a magnetostrictive digitizing tablet, and a teletype terminal, that accurately and quickly measures positions, lengths, and areas. Particular emphasis is given to interfacing, software, and to some applications in education and research of this minimum configuration system.…

The third in a series of reports on the educational applications of computers. Focuses on ERIC materials that can help educators learn more about the graphic capabilities of CRTs. (FL)

A technique is described for the generation of perspective views of three-dimensional models using computer graphics. The technique is applied to models of familiar thermodynamic phase diagrams and the results are presented for the ideal gas and van der Waals equations of state as well as the properties of liquid water and steam from the Steam…

Discusses computer graphics and computer-aided design in the freshman engineering program at the University of Texas at Austin. Procedure uses interactive modules that do not require any programing skills. An annotated test of modules used and suggested approaches that might be useful at other schools are included. (BC)

A total of 59 papers are compiled into these proceedings. The papers are organized alphabetically by each author's last name. A directory of speakers' names and addresses is included. In the index of this publication, papers are listed by session. General sessions are listed first, followed by 21 regular sessions: (1) "Logo and Music";…

Describes mathematical problems which occur when using the computer as a calculator. Considers errors in BASIC calculation and the order of mathematical operations. Identifies errors in spreadsheet and calculator programs. Comments on sorting programs and provides a source for Mathemagical Black Holes. (MVL)

This catalog was prepared for the Department of Vocational Career Development of Georgia State University as a supplementary manual to its recently developed catalog of courses. It is a survey of available literature on a wide variety of technical subjects formerly not included in traditional vocational or technical education in Georgia. Included…

Considers activities that use LOGO to slide, turn, and flip the "turtle." Uses non-LOGO tools such as cutouts, pattern blocks, and tangrams to enhance the motion work. Provides examples and programs with explanations. (MVL)

Notes two uses of computer spreadsheets in the chemistry classroom. Discusses the general use of the spreadsheet to easily provide changing parameters of equations and then replotting the results on the screen. Presents a molecular orbital spreadsheet calculation of the LCAO-MO approach. Supplies representative printouts and graphs. (MVL)

Provides a method to use superscripts and subscripts on the screen by using graphics screen modes. Gives two methods and provides a listing of a sample BASIC program. (MVL)

This report reviews four different computer systems that are available for educational use. Presented is a system overview, and the strengths and weaknesses of each of the following systems: PLATO, TERAK, Compucolor II, and PET. Each of these machines is included as a representative of a "class" of machines available to the educator.…

Builds on a National Science Foundation (NSF) microcomputer based laboratory project to introduce system dynamics into the precollege setting. Focuses on providing students with powerful and investigatory theory building tools. Discusses developed hardware, software, and curriculum materials used to introduce model building and simulations into…
