Short, visual illustrations can enhance a student's
understanding of many biological concepts or processes. Also,
the interest generated by presenting the right illustration at
the right time can be highly motivational for students. Laserdiscs
are excellent visual data banks. However, finding the ideal illustration
for biotechnology topics takes significant time, particularly
since many of the existing laserdiscs were not developed with
biotechnology as the main focus.
Two distinct advantages of using laserdisc images
are the ease and quickness for display, thus encouraging frequent
and varied use. Note that any specific image can be used to illustrate
a number of different biological ideas as the following question
How could a thirty-second video clip on white blood cells be used?
Possible examples include:
Creative teachers could certainly add to these examples.
Once identified, specific frame numbers can be stored in several ways as follows:
The accompanying three-page list includes all of
the information necessary to locate both still frame and video
clips useful for biotechnology related topics. The recommended
illustrations could be used directly from the table. However,
using a computer application would facilitate future retrieval.
This list references laserdiscs from two publishers,
Optical Data (one disc: Life Science) and Videodiscovery
(four discs: Anatomy & Physiology, Atoms to Anatomy;
BioSci II, and Cell Biology). The list is not comprehensive;
many more appropriate images can be identified by searching the
catalogs accompanying the laserdiscs.
Identify the biotechnology topic of interest
in the alphabetical list in the first column. Read across
the table for information on the image type, image description,
videodisc name, disc side and frame location numbers, and
run time for video clips.
