Abstract:
The World Wide Web has made a spectrum of image types from stills to digitized video available at students' fingertips. Hence, medical education could greatly benefit from web-based applications that utilize images or video. There are two limiting factors, however, that have hampered the pedagogical efficacy of web-based images and video. First, students typically do not have the adequate bandwidth to view high-resolution images or video over the web. Secondly, images or video in and by themselves do not create effective learning environments necessarily.
To address these limitations, we created a multimedia application
that lent itself for distribution over the Internet as well as via a
CD-ROM. To enhance the pedagogical
efficacy of this application, we added interactivity to the images, and
combined video with images and sound.
The application consisted of four sections:
·
Interactive Brain Atlas.
Over a hundred photographs of the central nervous system, including
overlays outlining major anatomical structures.
·
Interactive MRI Atlas: A
series of MRI images displayed in axial, sagittal and coronal planes, with or
without outlines.
·
Dissection Videos in Real and MPEG formats
·
Multimedia Tutorials, combining dissection videos, images, sound
and text, programmed in Synchronized Multimedia Integration Language (SMIL).
In addition, interactive quizzes were included with which students
could self-test their knowledge.
The CD-ROM will be demonstrated.
Development issues, such as instructional design, programming, costs,
and implementation, will be addressed.
Benefit in Attending
Session:
The demonstration would highlight the issues involved in creating an application that include video, interactive images and quizzes, and that can be delivered through the web or CD-ROM. The application uses a wide variety of technologies: MPEG and REAL video format, SMIL, HTML and JavaScript. Browser and platform compatibility issues will be explained.
