Monte Carlo methods are used to evaluate marginal maximum likelihood estimation of item parameters and maximum likelihood estimates of theta in the two-parameter logistic model for varying test lengths, sample sizes, and assumed theta distributions. Results with 100 datasets demonstrate the methods' general precision and stability. Exceptions are…

Provides information on software tools, technologies, strategies for evaluation, and factoring-in teaching considerations. Also included is an extensive review of computer-assisted language learning materials and a software evaluation questionnaire. (16 references) (GLR)

This second in a series of articles on a software evaluation project conducted by the Netherlands Association of Users of Online Information Systems (VOGIN) lists and compares specifications, properties, and test results for nine microcomputer-based software programs that fall into the category of classical information retrieval systems. (26…

Describes a study that analyzed the evolution of microcomputer-based instructional software for grades K-12 published from 1981-88. Four companies identified their most popular software and their most technically advanced software. Products in each category were analyzed to develop a chronology of the evolution of instructional software and to…

Presents specifications for software that is designed to support manual development and maintenance of information retrieval thesauri. Evaluation of existing software and design of custom software is discussed, requirements for integration with larger systems and for the user interface are described, and relationships among terms are discussed.…

Offers 10 guidelines for librarians responsible for making decisions on whether to upgrade application software. Examines the Internet, client/server LAN (local area network) architecture, developments in contemporary stand-alone systems, and graphic user interfaces to determine their impact on the upgrading process. (AEF)

Discusses the use of technology to individualize mathematics instruction for gifted students. The use of computers in a mathematics classroom allowed students to identify objectives, communicate results, and implement activities related to goals. Successful math software programs are highlighted. (CR)

Discusses the software review process recently completed at the University of Kansas that resulted in the adoption of an integrated Web course development package. Highlights include stakeholders represented on the evaluation team; establishing review criteria; identifying and evaluating software; demonstrations; and recommendations. (Author/LRW)

Evaluation of the impact of computer-related technologies on learning must take place within a theoretical framework consisting of theories, concepts, and principles to be meaningful. The framework provides the context of a research, its rationale, and its significance. The instructional theory and technology defined by Robert Gagne is selected as…

In today's growing technological age of educational software and interactive Internet teaching/learning websites, it is important to note that educators must take the time to see that the interactive electronic experiences their students are involved meet the appropriate standards, hence been evaluated. This article provides the readers with an…

A comparison was conducted of "Voxwire MeetingRoom" and "iVocalize" v4.1.0.3, both Web-conferencing products using voice-over-Internet protocol (VoIP) to provide unlimited, inexpensive, international audio communication, and high-quality Web-conferencing fostering collaborative learning. The study used the evaluation criteria used in earlier…

This article describes an integrated problem solving and program development environment, illustrating the application of the system with a detailed case study of a small-scale programming problem. The system, which is based on an explicit cognitive model, is intended to guide the novice programmer through the stages of problem solving and program…

This usability study evaluated users' perceptions of a multimedia prototype for a new e-learning tool: Anatomy of the Central Nervous System: A Multimedia Course. Usability testing is a collection of formative evaluation methods that inform the developmental design of e-learning tools to maximize user acceptance, satisfaction, and adoption.…

Recently, a lot of open source e-learning platforms have been offered for free in the Internet. We thus incorporate the intelligent diagnosis and assessment tool into an open software e-learning platform developed for programming language courses, wherein the proposed learning diagnosis assessment tools based on text mining and machine learning…

In Technology Enhanced Learning Environments, self-regulated learning (SRL) partly relies on the features of the technological tools. The authors present two environments they designed in order to facilitate SRL: the first one (e-Dalgo) is a website dedicated to the learning of algorithms and computer programming. It is structured as a classical…
