Frequently linked to sophisticated speech communication devices resembling laptop computers, augmentative and alternative communication (AAC) encompasses a spectrum of tools and strategies ranging from pointing, writing, gestures, and facial expressions to sign language, manual alphabet boards, picture symbols, and photographs used to convey…

In this article, the author asserts that technology is not the answer to digital piracy at colleges and universities. Citing the three most common explanations given for copyright infringement--that students cannot always get what they want, cannot always use what they can get, or think the price of what they can get is unfair--he asserts that the…

For those of you unfamiliar with clicker personal response systems, a clicker is a handheld remote that students use to enter their responses to multiple choice questions. The question is displayed on the classroom overhead screen, usually within a Power Point presentation, and a receiver connected to a computer at the front of the room collects…

The analysis of interaction among latent variables has received much attention. This article introduces a Bayesian approach to analyze a general structural equation model that accommodates the general nonlinear terms of latent variables and covariates. This approach produces a Bayesian estimate that has the same statistical optimal properties as a…

Knowing the meanings of common root words, prefixes, and suffixes may help students read and spell the longer words they begin to run into in the upper elementary grades. This article describes how students can use the Kidspiration computer program to quickly and easily create word webs that illustrate the meanings of common root words and…

Least-squares linear regression is the best of statistics and it is the worst of statistics. The reasons for this paradoxical claim, arising from possible inapplicability of the method and the excessive influence of "outliers", are discussed and substitute regression methods based on median selection, which is both robust and resistant, are…

This guide was developed as a "how to" training device for printing AppleWorks version 2.0 spreadsheet files using the Apple IIGS computer with two disk drives. Step-by-step instructions are provided for loading spreadsheet files; selecting the print option; printing entire files; and for printing specific rows, columns, or blocks of the…

This guide was developed as a "how to" training device for constructing spreadsheet files using AppleWorks version 2.0 and the Apple IIGS computer with two disk drives. Step-by-step instructions are provided for program loading, selecting the spreadsheet option, setting column widths, naming columns and fields, entering category…

A statement by Senator Orrin G. Hatch opened the hearing on The Computer Software Rental Amendments Act of 1988, a bill which would amend title 17, United States Code, the Copyright Act, to protect certain computer programs. The text of the bill is then presented, followed by the statements of four witnesses: (1) Dr. Alan C. Ashton, president,…

This guide was developed as a "how to" training device for printing spreadsheet files using AppleWorks on the Apple IIe computer with a Duodisk or two disk drives. Step-by-step instructions are provided for selecting the print option; printing entire files; and for printing specific rows, columns, or blocks of the file. For each step, a…

This guide was developed as a "how to" training device for constructing spreadsheet files using AppleWorks on the Apple IIe computer with a Duodisk or two disk drives. Step-by-step instructions are provided for program loading, selecting the spreadsheet option, setting column widths, naming columns and fields, justifying labels and…

Designed by the DEC Systems Research Center and the Olivetti Research Center, the programming language Modula-3 descends from Mesa, Modula-2, Cedar, and Module-2+, and resembles Object Pascal, Oberon, and Euclid. A notable feature of this language family is the use of modules to delineate the separation between the implementation and the use of…

In this brief guide, the use of microcomputer spreadsheet programs is discussed. Key characteristics are described, with examples of what these programs can do: calculations, recalculation, table lookup, data storage, logical decisions, and simple graphics. Advanced spreadsheet features are noted--consolidation, sort, and execute. Finally,…

A system to aid in the post-mortem debugging of assembler language programs written for the IBM System/360-370 series of computers is described in this master's thesis. A user's manual for the system, with descriptions of user requirements, Job Control Language (JCL) statements, and system output, comprises the first chapter. The program logic…

The National Assessment of Educational Progress Information Retrieval System is a single purpose database program. It is well constructed, runs without problems, and serves as a model for dissemination of research and evaluation study results. The program seems more useful as an index to documents than as an independent database. (Author/DWH)
