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)

Describes four studies of high school students that examined the effectiveness of user-adaptive computer-aided instruction that explicitly models the cognitive processes of composing for developmental writers and is integrated with classroom composition instruction. Discusses the design and use of the writing software R-WISE (Reading and Writing…

Discusses the results of a survey in which 291 parents of an urban elementary school reported on their computer equipment at home, the type and frequency of their children's educational software and Internet use, and shared their ideas how better connections between computer use at home and school might be created. (Author/LRW)

Reviews research describing computer functions of construction-oriented computer environments and evaluates their contributions to students' learning of geometry. Topics discussed include constructing geometric concepts; the use of LOGO in elementary school mathematics; software that focuses on geometric construction; and implications for the…

A multi-stage study of the practices of expert courseware designers was conducted with the final goal of identifying methods for assisting non-experts with the design of effective instructional systems. A total of 25 expert designers were involved in all stages of the inquiry. A model of the expert courseware design process was created, tested,…

Discusses research evidence for not including microcomputers in preschool environments; develops a theoretical base favoring computer use in early childhood that includes views of Papert, Piaget, Erikson, and competence development; and offers directions for software development through a review and description of successful microworld programs.…

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 multimedia-based Russian language course developed at Colgate University (NY) and a multimedia authoring system that makes the creation of such courses technically feasible for language instructors. The use of movies, foreign language instruction, principles of design, development frameworks, and future plans are discussed. (Author/LRW)

Investigates the benefits of using culturally responsive reading material and a computer-based learning environment in literacy instruction. Describes a study of low socioeconomic status first through fourth grade African American children that tested two computer programs that use prior knowledge as scaffolds for early literacy instruction.…

Based on the decomposed theory of planned behavior, this study used path analysis to examine the relative strength of the factors that influence teachers' use of instructional technology. The study focused on teachers' use of word processors, spreadsheets, presentation software, e-mail, and Web browsers. A path analysis was performed on…

Describes the design principles behind a set of research-based software microworlds included in the "Building Blocks" program, a pre-kindergarten to grade 2 software-based mathematics curriculum. Discusses how to help children extend and mathematize their everyday activities and presents the nine-step design process model used.…

Explains TIMA (Tools for Interactive Mathematical Activity), that were designed to provide elementary schools children with contexts in which they could enact mathematical operations. Discusses differences from drill and practice software; provides examples of how the TIMA were used by children to engage in cognitive play; and emphasizes the…

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.…

Discusses computer-based learning environments and presents results of empirical research on ESL (English-as-a-Second-Language) college students' work within a learning environment designed to help with elements of grammar. Topics addressed include illocutionary versus nonillocutionary natural language learning environments and correlations…

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…
