1. Learning Episode 14:
Maximizing the use of the
Overhead Projector and the
Chalkboard

2. Except extremely deprived
classrooms, every classroom has a
chalkboard. In fact, a school may
have no computer, radio , TV, etc.
but will always have a chalkboard.
The following practices of
dedicated personal teachers may
help us in the effective use of the
chalkboard:
• The Chalkboard

3.  Write clearly and legibly on the
board.
 It helps if you have a hard copy of
your chalkboard diagram of outline.
 Don’t crowd your notes on the board.
 Make use of the colored chalk to
highlight key points.
 Do not turn your back to your class
while you write the chalk board.

4.  For the sake of order and clarity,
start to write from left side on the
board going to the right.
 If you can teach the Grades and you
think the lines on the chalkboard are
needed for writing exercise , then
provide line for the board.
 Look at your board work from all the
corners of the room to the test if
the pupils from all sides of the room
can read your board work.

5.  If there is a glare on the
chalkboard at certain times of the
day, a curtain on the window may
solve the problem.
 If you need to replace your
chalkboard or if you are having a
new classroom with new chalkboard
suggest to the carpenter to mount
the chalkboard a little concave
from the left to right to avoid glare
for the pupils benefits.

6.  If you need to have a board work in
advance or that need to be saved
for tomorrow ‘s use write “please
save” and cover the same with
curtain.
 Make full use of the chalkboard.

7.  Sharpen your chalk to get good line
quality.
 Stand with your elbow high. Move
along as you write.
 Use dots as “aiming points”. This
keeps writing level.
 Make all the writing and printing
between 2 and 4 inches high for
legibility.
 Hen using colored chalk, use soft
chalk so that it can be erased easily.

8. • The Overhead Projector(OHP)
There are other kinds of projector like
opaque projector and slide projector. The
overhead projector seems more available in
schools.

9. Advantages of Overhead Projector
by Brown:
 Projector itself is simple to operate.
 The overhead projector is used in the
front of the room by the instructor, who
has complete control of the sequence,
timing and manipulation of his material.
 Facing his class and observing the
students reactions, the instructor can
guide his audience, control its attention
and regulate the flow of information in
the presentation.

10.  The projected image behind the
instructor can be as large as necessary
for all in the audience to see; it is clear
and bright, even in fairly well- lighted
room.
 Since the transparency, as it is place on
the projector, is seen by the instructor
exactly as students see it on the screen,
he may point, write, or otherwise make
indications upon it to facilitate
communication.

11.  The stage, of the projector is large, thus
allowing the teacher to write information
with ease or to show prepared
transparencies. His works appears
immediately on the screen.
 It is especially easy for teachers and
students to create their own materials
for use in the overhead projector.
 An increasing number of high- quality
commercial transparencies.

12.  You can show pictures and diagrams,
using a pointer on the transparency to
direct attention to a detail.
 You can use a felt pen or wax based
pencil to add details or to make points on
the transparency during projection.
 You can control the rate of presenting in
formation by covering a transparency
with a sheet of paper or card board and
then exposing data as you are ready to
discuss each point.
Overhead Projection techniques

13.  You can superimpose additional
transparency sheet as overlays on the
base transparency so as to separate
processes and complex ideas into
elements and present them in step by
step order.
 You can show three dimensional objects
from the stage of the projector – in
silhouette if the object is opaque, or in
color of an object is made of transparent
color plastic.

14.  You can move overlays back and forth
across the base in order to rearrange
elements of diagrams or problems.
 For special purposes you can simulate
motion on parts of a transparency by
using the effects of polarized light.
 You can simultaneously project on an
adjacent screen other visual materials ,
usually slides or motion pictures, which
illustrate or apply the generalization
shown on a transparency.
