Describes EntryWay, a hypertext authoring extension for HyperCard, and presents eight case studies that examined hypertext navigation patterns created by seven users of EntryWay. Five patterns of navigation are identified and explained, comparisons of navigation patterns are discussed, and implications for hypertext use are suggested. (17…

Reports on a survey which assessed automated authority control capabilities of 18 vendors' automated library systems, software, or services. Graphs rank vendors according to overall score, authority record source, format/storage of authority records, database dynamics, matching/linking authority and bibliographic records, syndetic structure,…

Describes GeoWorks, a new graphical user interface (GUI) that works on older, less powerful IBM PCs and compatibles. The PC/GEOS (PC/Graphical Environment Operating System) is explained, user friendliness is emphasized, comparisons are made to Microsoft Windows, and GeoWorks applications software is described.

Analyzing the motion of the human tongue surface provides valuable information about speech and swallowing. One method to analyse this motion is to acquire two-dimensional ultrasound images and extract the tongue surface contours from them. Quantitative and statistical analysis of these extracted contours is made difficult because of the absence…

The paper presents a theoretical framework addressing three aspects of embodied pedagogical agents: visual static appearance, pedagogical role, and communicative style. The framework is then applied to a user study where 90 school children (aged 12-15) in a dummy multimedia program were presented with either an instructor or a learning companion…

The purpose of the present research study was to examine effects of the use of SmartMusic practice software on the intonation and rhythmic accuracy of brass players' musical performances. Twenty college brass players who served as participants in the four-week study were randomly assigned to one of two practice conditions. The WSM (With…

The No Child Left Behind Act of 2001 (NCLB) effectively shifted the K-12 educational paradigm to a system that places a high premium on performance and accountability. The impact of the NCLB legislation and the adoption of the Nevada High School Mathematics Proficiency Examination (NHSPEM) have created the need for instructional materials that…

Discusses formative evaluation of courseware and describes a study of undergraduates that compared the effects of two methods of formative evaluation on the revision of a computer-assisted instruction (CAI) program written in HyperCard. Use of the one-to-one method and the small group method of evaluation are explained, and posttest scores are…

Examines and compares five available computer programs intended for self-instruction in Italian, focusing on their attention to learning strategies and personalized learning pace. Content, format, and other features of each are noted. General issues discussed include overall organization, cultural content, sequencing, exercise types, and ancillary…

Variable selection techniques in stepwise regression analysis are discussed. In stepwise regression, variables are added or deleted from a model in sequence to produce a final "good" or "best" predictive model. Stepwise computer programs are discussed and four different variable selection strategies are described. These…

The Johnson-Neyman (JN) technique is a parametric alternative to analysis of covariance that permits nonparallel regression lines. This article presents computer programs for J-N using the transformational languages of SPSS-X and SAS. The programs are designed for two groups and one covariate. (Author/JAZ)

This bibliography, prepared with the information specialist, end-user, and administrator in mind, presents citations to 167 journal articles that provide concrete comparisons of commercially-available microcomputer software packages and hardware equipment. An index divided into software and hardware sections with references to type of comparison…

Compares three letter libraries designed for IBM-style personal computers. Finds the quality of the three approximately equal, but rates sample letters as generally poor. (MS)

Identifies essential database management terminology and groups the various types of database management programs into three basic categories for discussion of basic features, typical applications, and costs. A table of the leading programs available in each category includes the manufacturer's name and address, hardware requirements, and price…

A computer program is described which provides comprehensive information on test profile differences among independent groups based upon profile centroid separation, shape, elevation, and scatter. Descriptive statistics, univariate and multivariate measures of strength of association, test of homogeneity of covariance matrices, and comparative…
