Two computer-intensive procedures are presented for dealing with non-random selection in the development of samples for experimental, quasi-experimental, and survey designs associated with educational research. The procedures are randomization tests to clarify treatment effects and bootstrap techniques to estimate the uncertainty of…

Describes the development and implementation of software that provides a global change capability by allowing correction of a single heading in a large file of bibliographic records through programatic identification and replacement. Specific change processes are described, including name headings, geographic headings, and topical subject…

This article describes a system based on the Epson HX-20 used for real time (rather than time-sample) recording of behavior observation data, which allows the researcher additional options in analysis. Examples of the programs developed, types of research questions asked, and data analyses conducted are provided. (Author/PB)

An instructional model is described for integrating the microcomputer into the mathematics curriculum. Development, understanding, higher order thinking, and applications are elements of the model. Software is identified for each element. The roles of telecommunications, spreadsheets, databases, graphics, and graphing in mathematics curricula are…

Muppet Slate, a writing program used on Apple computers, is described, along with its successful integration into a kindergarten language arts program. Students can write original stories illustrated with a choice of 126 pictures. Utilities enable teachers to customize the program to meet student needs. (IAH)

The article describes 14 recent devices and software programs which can be used to improve access by special needs populations to the Macintosh computer. (Author/DB)

Describes and evaluates three software programs for elementary level language arts: (1) "The Princess and the Pea," which connects the fairy tale with the modern world; (2) "PreWrite, Level 1," which helps students identify and develop writing topics; and (3) "Dinosaur Days," a creative graphics and publishing program with speech capabilities. (MM)

Presents a system of software and analysis for the development of mathematical models designed to explain the structure in large bibliographic data sets. The discussion covers the goodness of fit obtained in testing and replications, and the implications for the control of large information systems. (six references) (CLB)

Discusses wire capture programs (computer programs which gather and process wire services such as the Associated Press or United Press) for computer labs in journalism departments. Describes details of such programs for Macintosh, IBM, and IBM clones. (SR)

Describes implementation, support, and evaluation of computer assisted learning (CAL) projects at three universities: Project Athena at Massachusetts Institute of Technology; the Andrew network at Carnegie Mellon University; and a project at Stanford University. Topics discussed include work stations, microcomputers, computer networks, graphics,…

Although many of the criteria used to evaluate traditional instructional materials can be applied to the instructional aspects of computer-assisted instruction, additional criteria must be considered. These include interactivity, individualized feedback, rapid calculation, graphics, and cost-effectiveness. (JOW)

Discusses the World Wide Web (W3) and its relevance to a philosophy of science. Topics include PORIDGE, an electronically mediated encyclopedia of postmodern knowledge; hypertext mark-up language; W3 as a medium for information ecologies; the relationship between W3 and the user; social manufacture of knowledge; and W3 as a model. (29 references)…

A qualitative, holistic framework is presented for the process of evaluating foreign language software. Eleven specific steps are outlined, and a list of educational software evaluation agencies is appended. (Contains 21 references.) (LB)

Discusses the types of overlapping speech, a common characteristic of speech that any annotation system must deal with. Critiques two types of current systems for marking overlaps. Describes software developed by the authors that not only accurately marks the boundaries of overlaps but presents them to the user in a readable format. (SR)

Discusses limitations in the development of health care information systems; explains component methodology for complex software development, including component interface semantics; and describes Arachne, a development environment available via the Internet consisting of a set of tools that enables applications to be constructed through…
