While it is true
that a PowerPoint presentation is easy to read and the outline makes navigation easy, most
instructors use PowerPoint as a scaffold for in-class note taking. This may be an
excellent use of the web lecture. However, instructors rarely design their notes as
stand-alone products. They rationalize that they will be "filling in the blanks"
in class, or they use the notes as a reference for their own lecture material. Notes that
are prepared from this perspective can appear disjointed to a reader who is unfamiliar
with either the author or the topic. We also need to consider the availability of the
web to our potential audience. In the case of SHRS, web lectures are intended as public
offerings. We cannot assume that everyone enjoys convenient and inexpensive web access.
Therefore, in order to extend the advantage of online materials, information needs to be
available in forms easily downloaded. |
