The
teaching console in each studio has a "flexcam", which is a
small color video camera mounted on a jointed flexible arm.
These cameras have proven very versatile in their uses.
(Right) An instructor uses the flexcam to show to her class
an image from a textbook. Though the image is small in the textbook,
it is large on the TV screen so everyone can see it easily.

flexcam (below left) is used here in a chemistry demonstation
to provide a close-up view of a chemical reaction . The flexcam
provides the students with a large detailed image (below right).

Cameras
like these are also used in the classrooms that receive our
distance education courses. The students use them to show
their in-class projects, or for the instructor to check their
homework
assignments, or even to troubleshoot a math problem. The
instructor
can see what the students are doing wrong on their papers and
help them correct mistakes just as if they were physically
in
the same classroom. |
