The only mistake would be to apply such technology just because it's available or interesting. The weather web sites provide displays which are produced from constantly changing data. Data base entry. Student responses to open or closed questions can be recorded in a data base. The data collected can be reviewed by the instructor, automatically processed for review by the instructor or display to students, or even used as a basis for selecting or creating other pages presented to the student.
Web pages can include sound sequences and video clips.
Animated visuals can be produced either by the server or client computers with ramifications affecting the access and display times. Frequently updated clips, for example a small picture of the instructor explaining the homework, can actually become a form of broadcast supplementing message directed CMC interactions . Scrollable pop-up windows can be invoked by buttons, sliders and dials can provide input and output, instructions and explanations can be displayed as the student moves the mouse around in the material. Being standardized these affects require a relatively modest investment in production. Technology for web production is available at UVI, and more is being acquired.
