Traditional methods of teaching the laboratory course for Comparative Anatomy of the Vertebrates could be improved by applying current computer technology to construct an interactive, multimedial atlas of dissection. Five specimens used in comparative anatomy courses at most institutions were chosen as representative members of the Phylum Chordata: amphioxus, lamprey, dogfish shark, mud puppy, and cat. Specimens were dissected according to the modified method of Wischnitzer, 1993, and each stage was photographed with a Kodak DC120 digital zoom camera. These images were processed on a Power Macintosh 7600 computer with Adobe Photoshop v. 5.0. The atlas was constructed from these images using Macromedia Authorware v. 4.0.3. Each image contains a series of interactive objects that display a highlight and descriptive text as the cursor passes over each object.

In response to ideological issues that have emerged the last two decades from feminism, multiculturalism and postmodernism, the introductory art history survey is undergoing major revisions not only in structure and content, but also in instructional methodology. Art history professionals and art educators alike are questioning whether pedagogical methods traditionally employed in the survey are adequate for meeting the goals of visual literacy and development of critical and analytical skills. The purpose of this study was to investigate the effectiveness of supplemental study resources for art history survey students, specifically an interactive multimedia (IM) computer program designed to help students acquire and retain a deeper understanding of works of art. Two research questions were asked: Is IM a more effective instructional format than traditional slide study on achievement measures? Will use of IM impact students' levels of understanding and strengthen and direct their choice of search strategies?

The United States is in an emerging period of transition, shifting to online multimedia campaigns. This research attempts to explore general knowledge of multimedia expansion, and through qualitative research methods provide a successful model for the development of an effective promotion tool. Findings from the heuristic study showed users preferences for varying forms of media, thus demonstrating the need to provide content in many different forms. The findings from this study aide in the development of multimedia, and illustrate the need for further studies in the use of multimedia as a promotion tool. / Department of Telecommunications

Dinner For One, a hypermedia poetry thesis, explores the themes of aloneness, sexuality, independence, and journeys of discovery and distance. The Chinese zodiac stamps used as navigational elements in Dinner for One and the prose poems written as postcards to oneself an others reinforce the notion of travel. The fortunes from Chinese cookies give prophecies and horoscopes, reminding us of our fate, which is beyond our conrol. Dinner For One means to question, through poetry and interactive, hypertextual reading techniques, how much faith and trust we should hold in influences outside of our lives. The poems in this thesis are meant to be an examination of what we tell ourselves and, sometimes, make ourselves believe.This multimedia, interactive presentation is written with Macromedia 2000.

Multimedia technology enables direct manipulation of multiple media such as text, image, audio, and video, all integrated into one entity - the multimedia document. Interactive multimedia documents integrate text, images and continuous media such as audio and video, treat them as objects to be presented for a certain duration, and allow users to interact with the presentation. Authoring and presenting interactive multimedia documents imposes new requirements on document representation. We designed the interactive timeline model (ITM) for authoring and presenting interactive multimedia documents. We implemented the model and created a playback tool using the scripting language Tel. ITM uses an enhanced timeline model for representing interactive multimedia scenarios. ITM is a layered model that supports the creation of the logical, temporal, and presentation structures of a multimedia document and emphasizes the separation of content from its structure. The storage layer provides interfaces for creation and storage of media objects like text, images, scripts, choices, and audio. Choice is a media object that allows users to interact with the presentation. A script object causes Tel code to be executed. The composition layer specifies the logical structure and provides interfaces to compose a multimedia document. The presentation layer specifies the temporal and spatial structure of the document and describes the user interface for the playback tool. The run-time layer specifies the interfaces to start and control the flow of the presentation, describes the possible interactions between a user and the presentation at run-time, and specifies the actions to be taken when interaction takes place. ITM allows users to configure the playback tool according to their needs. It provides authors with a mechanism to create new interfaces and register them with the playback tool. To evaluate the design decisions of ITM and verify its usability, we conducted usability tests on the model. We asked a representative sample of end users ( both authors and viewers) to perform realistic tasks using the model. ITM is a powerful model to create and present interactive learning materials and dynamic presentations.

A key feature of recent agricultural extension programs has been the focus on increased participation for local, rural communities in the overall decision-making process. This move towards increasing community participation has raised expectations in terms of communication: communication between central research facilities and rural communities, between rural communities and central research facilities, and amongst the rural communities themselves. In order to provide effective communication along each of these channels, attention is turning to the extension trainers deployed in the field. For extension trainers this emerging communication role is distinct from, and supplementary to, the conventional technical training function. The thesis highlights the lack of effective training in communication skills in existing extension training programs. It identifies the flip chart as the most widely used visual aid for farmer training, and the overhead projector as the most widely used visual aid for in-service training. The thesis develops a comprehensive set of training competencies and content for teaching those two technologies, derived from individual task analyses and an extensive literature review. A range of strategic alternatives for the delivery of those competencies in a developing country are then formulated and examined. Central to the different strategies considered is the use of interactive multimedia as a key delivery technology. Two proprietary CDROMs have been designed and produced specifically to the support training in the design and production skills for overhead projector and flip chart technologies. The design, content and production of the CDROMs is described, and both technical and user evaluations are presented. The two CDROMs have been field-tested in Sri Lanka, across a broad range of strategic alternatives. The outcome is a set of guidelines and specific structures for training programs in overhead projector and flip chart technologies. The guidelines are generic and broadly applicable. The case studies also indicate a particular subset of preferred strategies for the future deployment of interactive multimedia-based training in developing countries. Most specifically, the thesis indicates a balance between and the need for mix of interactive multimedia modules along with face-to-face training support / Doctor of Philosophy (PhD)
