Discusses methodological issues of mathematical microworld development integrated with generating innovation in school settings. Includes experiences in developing a component architecture for educational software based on Logo as a scripting language and discusses problems of collaboration between organizations and people of differing expertise…

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)

Introduces the Inventive Model, a constructivist approach to conceptual change, as a theoretical base for science instruction and for software development in science education. Highlights include the hesitancy of some school systems to implement computer-assisted science instruction, student misconceptions, and cognitive approaches to conceptual…

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 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.…

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)

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…

Discussion of the time needed to create computer-based instruction focuses on descriptive analyses of production data gathered from novice instructional designers and novice authors who used a commercial authoring system to produce computer-based lessons. Production ratios are explained, and future research plans are discussed. (Contains five…

Describes the design and evaluation of a desktop virtual reality program that was developed to teach children about the accessibility and attitudinal barriers encountered by their peers with mobility impairments. Investigated attitudes, grade levels, familiarity with individuals with a disability, and gender. (Author/LRW)

Describes the development of a computer-based learning courseware that presented associative learning between abstract and concrete domains and discusses results of a study of college students that determined whether various audio-visual combinations and differences in IQ levels influenced learning and long-term retention using the courseware.…

Discusses improving mathematical reasoning through the design of computer microworlds and evaluates a computer-based learning environment that uses multiple representations to improve undergraduate students' conception of average speed. Describes improvement of students' estimates of average speed by using visual feedback from a simulation.…

Describes design considerations that were made for a software prototype called the Virtual Library that were framed by cognitive research and learning theory. When completed, the software will assist preservice teachers in learning about educational psychology and instructional design. Topics include constructivism, exploratory learning, authentic…

Discussion of graphing software for educational purposes focuses on a study in which three versions of an original computer graphing program were used by inner-city high school students to solve scientific data analysis problems. Variations in degrees of flexibility and feedback in the software are explored. (Contains 37 references.) (LRW)
