b. Summarize Material by Venetian Blind. Venetian blind strips should be
summarized in the order they were taught. Start from the top and then summarize from
the top. This provides mental drill for the student. Do not try to question from the
unexposed portion of the Venetian blind, since this would be asking the student to
guess what would be exposed next. If wipe-off lettering is used, you can reuse the
same strips for another lesson. See figure 3-1 for an example of a Venetian blind
device.

3-24. THE CHALKBOARD
The chalkboard is a flexible and useful training aid. It is often used incorrectly
because its potential for use and the techniques are misunderstood.
a. Multi-Use. A chalkboard can be used in many ways. You can place topics,
questions, sketches, diagrams, teaching points, or other written material on the
chalkboard. By using the overhead projector or the opaque projector, transparencies,
pictures, or graphs can be projected on the chalkboard and then traced in chalk for
greater visibility.
(1) Template. A template (pattern or gauge) can be a guide in making
drawings accurately or in reproducing a standard object when drawing on the
chalkboard.
(2) Trace drawing. If you use a pencil to trace a drawing in advance, you
can trace it later in chalk to show a clearer and more professional picture to the
students. This is very convenient for those items you want to show by sections during
class.
