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)

Investigates the effect of activity content, its presentation, and the interactions between the two on flow experience (intrinsic motivation) in instructional activity. Results suggest that activity content has major influences on motivation; hypermedia presentations can add to motivation if used appropriately, or they can be distracting if too…

Describes a study of fifth graders that examined the effects of learner control and navigational aids on performance in a hypermedia instructional program. Results indicated that students who moved freely within the program and had access to navigational aids, interacted more with the program and achieved higher performance on posttests.…

This study proposes a hierarchical hyper concept map (HHCM) course system which consists of a navigation map, concept maps, and hypermedia documents. Results of testing the HHCM as a course representation showed achievement was greater for students learning from the course represented by HHCM compared with those learning from a linearly…

Describes a study that examined the potential of a hypermedia-based expert tool to scaffold regular education sixth graders engaged in a problem-based learning program. Topics include cognitive apprenticeship support for problem-based learning; using hypermedia to offer expert modeling; attitudes toward the learning environment; and self-directed…

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…

Describes a study of Australian secondary school students that identified the conditions and individual characteristics that would best support learners' acceptance of control within hypermedia, based on evidence from the learner control literature. Investigated effects of prior domain knowledge, learning activity structure, ability, and attitudes…

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…

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…
