e. Follow Up. Follow up the film. Allow the students to ask questions about
what they have just seen. Lead an oral discussion of the main points and discuss errors
or possible points of confusion in the film. If the film involves a procedure the students
will do, the instructor should demonstrate this procedure. Students should have a
practical exercise period where they can practice the procedure themselves. Next,
there should be a critique of the students performance. Often a second showing of the
film will help the students to understand how they can improve their performance.
3-27. FILM STRIPS
A filmstrip consists of a length of standard motion picture film containing still
pictures of a specific subject. There is usually a script describing each frame for the
instructor to read. If not, the instructor should explain each frame. Sometimes there is
an audiotape to use. Use your pointer as you find necessary. The picture sequence
can be stopped at any time for discussion on points of confusion. It is best to have an
assistant operate the projector to allow the instructor freedom of movement.
3-28. OVERHEAD PROJECTOR
The overhead projector (see figure 3-2) projects large transparencies onto a
screen or flat wall surface and is widely used by the Army instructor. Overhead
projectors are available through audiovisual communication centers.
