Examined Project Essay Grade (PEG) software for evaluating Web-based student essays that serve as placement tests. In the first experiment, a sample of student essays was used to create a statistical model for the PEG software; the second experiment compared computer and human ratings of essays. Found that the software is an efficient means for…

Describes a study that used a Web-based survey and a modified Delphi technique to identify criteria important to multimedia instructional courseware evaluation, validate them with a panel of instructional technology experts, and examine the effect of conducting panel discussions online. Shows information accuracy and reliability as the most…

This paper describes the creation and evaluation of a World Wide Web-based courseware module, using conceptual models based on constructivism, that teaches novices how to use the Internet for searching. Questionnaires and interviews were used to understand the difficulties of a group of novices. The conceptual model of the experts for the task was…

Character strings were planted in a World Wide Web site (Project Whistlestop) to test indexing and retrieval rates of five Web search tools (Lycos, infoseek, AltaVista, Yahoo, Excite). It was found that search tools indexed few of the planted character strings, none indexed the META descriptor tag, and only Excite indexed into the 3rd-4th site…

Describes a study of the retrieval results of World Wide Web search engines. Research quantified accurate matches versus matches of arguable quality for 200 subjects relevant to undergraduate curricula. Both "evaluative" engines (Magellan, Point Communications) and "nonevaluative" engines (Lycos, InfoSeek, AltaVista) were…

This study tested two Web personal spiders (i.e., agents that take users' requests and perform real-time customized searches) based on best first-search and genetic-algorithm techniques. Both results were comparable and complementary, although the genetic algorithm obtained higher recall value. The Java-based interface was found to be necessary…

This first phase of a content analysis of online, asynchronous, educational discussions is designed to generate a method for automatically categorizing messages into cognitive categories using neural network software. This phase of research answers two questions regarding the method of automatically analyzing discussion messages: Can a neural…

A science classroom was used to study the effects of a shared intranet environment on students' problem-solving ability and metacognitive reflection skills through shared contextualization. Subjects were first-time 9th- and 10th-grade biology students from three public high schools. An evaluative analysis of the CourseInfo software (Blackboard,…

This paper reports the results of a study of the development of an innovative learning element designed to be implemented in a computer-facilitated learning (CFL) module. The learning element is an open-ended, short answer, text question tool (TQT) designed to be used in World Wide Web-based courses or incorporated into hybrid Web/CD-ROM systems.…

This paper presents the outcome of research that deals with the development and use of World Wide Web hypermedia courseware in student teachers' education in the Department of Information Science at the Faculty of Philosophy, University of Rijeka (Croatia). The purpose of this research is to explore how the use of Web courseware improves the…

This paper presents the results of three years of development and evaluation of a CD-ROM/Web hybrid simulation known as Brownfield Action for an introductory environmental science course at an independent college for women in the northeastern United States. Brownfield Action is a simulation that provides a learning environment for developing the…

This paper describes a study that attempted to ascertain the degree of success that undergraduates and graduate students, with varying levels of experience using the World Wide Web and Web search engines, and without librarian instruction or intervention, had in locating relevant material on specific topics furnished by the investigators. Because…

Evaluation of data from assessments of full bibliographic displays in academic library OPACs (online public access catalogs) and World Wide Web catalogs against a checklist of desirable features found that OPAC displays scored 58% and Web displays scored 60%. Discusses weaknesses, focusing on those found in the majority of the displays…

For more than 5 years, Mexico's El Instituto Tecnologico y de Estudios Superiores de Monterey (ITESM) has offered distance education programs in addition to traditional face-to-face programs. ITESM has recently begun migrating to new e-learning platforms (Blackboard and Web Tec) that are more user-friendly and flexible than its previous e-platform…
