The purpose of this study was to use multiple data sources, both objective and subjective, to capture students' thinking processes as they were engaged in problem solving, examine the cognitive tool use patterns, and understand what tools were used and why they were used. The findings of this study confirmed previous research and provided clear…

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…

Some studies of hypertext/hypermedia systems have concluded that there is little evidence supporting its educational efficacy. After examining conceptual and methodological shortcomings of research, this article suggests that the educational potential of hypertext/hypermedia has been underestimated and argues that overcoming these shortcomings…

Discusses how to design courseware programs that integrate benefits of instructionism (linear instruction) and constructionism in a hypermedia structure. A model of feedback that fades in and out is suggested, four examples are explained, and suggestions for redesigning programs are given. (LRW)

Discussion of information exploration and software design in computer-based educational systems focuses on the integration of hypermedia and natural language dialog. AlFRESCO is described, an interactive natural language-centered multimodal system that was developed for users interested in frescoes and paintings. (LRW)

Findings from a study investigating students' reactions to a hypermedia program used to analyze real-life interactions indicated that pragmatic awareness can be developed in virtual culture contact situations. Similar interactive software in combination with ethnographic activities may be more effective in culture teaching and learning.…

University students (n=15) were asked how a hypermedia program's features reflected 4 theoretical constructs, 2 linear models (semantic networks, frames/scripts), and 2 nonlinear models (concept maps and schemata). Regardless of hypermedia experience, students cited more linear than nonlinear models, suggesting that more experience in programming,…

This investigation was designed to determine the influence of metaphorical priming on students' comprehension of issues and concepts pertaining to the U.S. Constitution when students studied the subject matter in a problem-based hypermedia instructional system. Sixty-five high school seniors studied the system for 5 days after receiving relevant,…

Presents methods and outcomes of a semester-long course involving cooperative hypermedia authoring and instructional strategies for preservice teachers. Posttest findings revealed that participants showed a decrease in computer anxiety through their involvement in the course, and the lowest levels of anxiety were associated with graduate rank and…

Describes the design of a hypermedia tool for helping preservice teachers learn about the growth and development of children's mathematical reasoning based on research in cognitive science, and discusses results of an experiment that used single-subject methodology to compare preservice teachers' learning with the hypermedia tool versus learning…
