Examines the effects of type of instructional control (learner control versus program control) and program mode (full versus lean) on the achievement, option use, time in the program, and attitudes of higher-ability and lower-ability university students using a computer-delivered instructional program. Discusses implications for instructional…

Describes a co-evolutionary model for supporting the emergence of authenticity through a partnership between preservice teachers and practicing teachers who collaborated in real-world tasks. Discusses authenticity and participatory learning; simulation models; participation models; uses of technology; communities of practice; power and control;…

Investigated the use of rapid prototyping methodologies in two projects conducted in a natural work setting to determine the nature of its use by designers and customers and the extent to which its use enhances traditional instructional design. Discusses design and development cycle-time reduction, product quality, and customer and designer…

This theory-based article describes how data analysis tools, simulations, and modeling software, when used in the proper instructional contexts, provide young learners with rich intellectual environments for inquiry in science learning. Highlights include inquiry learning; abilities of learners; and the integration of technology within classroom…

Discusses latent semantic analysis (LSA), a statistical model for representing word usage in written language, and describes two experiments that were conducted with undergraduates to determine what aspect of knowledge, conceptual or factual, is being reflected in an LSA output from student essays. (Contains 21 references.)u (Author/LRW)

Discussion of computer literacy and the rapidly changing face of technology focuses on a study that redefined computer literacy to include competencies for using graphical user interfaces for operating systems, hypermedia applications, and the Internet. Describes the development and testing of the Computer Interface Literacy Measure with…

Examines the extent and characteristics of Internet use among junior- and senior high school students in Israel. Discusses the link between Internet use and school activities, age and sex differences, and findings that indicate primary use is for communication with search for information as a secondary reason for Internet use. (Contains 16…

Considers the role of cognition in language learning and explores constructivism and Bloom's taxonomy of higher-order thinking skills. Topics include four basic types of computer assisted language learning, cognitive development, and the Internet. Lists pertinent resources, including printed materials, journals, and Web sites. (Contains 90…

Describes a study that investigated whether second grade students internalized content and concepts embedded in a science computer simulation as opposed to treating it as a game to be played. Discusses cognitive outcomes and processes, thinking skills, use of scientific language, transfer to other contexts, and partner and gender considerations.…

Examines the optimal scope for the navigation map in hypermedia courseware. Compares the influence of the scope of the navigation map on disorientation of participants, 146 fifth-grade students. Results show: the navigation map scope impacted pupils' performance in terms of searching steps; a larger field is better, although it does not…

Examines how technology was utilized within a student-centered project-based class, as well as students' beliefs about their technology use. Findings indicated teachers and students held differing conceptions on what was valued in class. Students spent much more time on technology-related skills than on exploring content. Content learning occurred…

Outlines conditions that should be present in an electronic tutoring system, and describes the Electronic Homework system.

Gives an example of the tutoring process, and examines the overall effects of using Electronic Homework. (AEF)

Describes "Glass-box Interpreter" a low-level program visualization tool called Bradman designed to provide a conceptual model of C program execution for novice programmers and makes visible aspects of the programming process normally hidden from the user. Presents an experiment that tests the efficacy of Bradman, and provides experimental…

Investigates the effects of audio and text density on the achievement, time-in-program, and attitudes of 134 undergraduate students. Data concerning pre-existing computer skills/experience and demographic information were also collected. Findings have implications for the use of audio, text and graphics in the design of computer-based instruction.…

Considers the effects of feedback on memory with an emphasis on retention of initial error responses. Applies a connectionist approach to explain feedback effects. High school students completed a computer-based lesson with either delayed feedback, single-try immediate feedback, or multiple-try immediate feedback. Findings indicate a connectionist…
