The document provides guidance on effectively using the chalkboard and overhead projector in a classroom setting. It offers tips for chalkboard techniques like writing clearly, using color chalk, and checking visibility from all angles. Advantages of the overhead projector include ease of use, ability to guide an audience, and allowing identical images for students and teachers. Suggested techniques involve using a pointer, felt pens on transparencies, controlling presentation pace, and avoiding too much text. Progressive disclosure and overlaying techniques help reveal information step-by-step. The document emphasizes facing students, simple graphics, and avoiding reading text verbatim.

Start writing from left to right for the sake of clarity and
order.
You can provide lines on your board if necessary.

8. Look at your board from all sides of the classroom to test if
your pupil can see your work.
You can use the window curtain to remove glare on your
board.
Suggest to the carpenter to make a concave chalkboard if you
need to replace the old one.
If you need to have board work in advance or that need to be

9. Sharpen your chalk to get good line quality.
Stand with your elbow high and move along as you right.
Use dots as “aiming points”.
Make all writing between 2 to 4 inches high.

12. Advantages
It is easy to operate.
The instructor can guide his audience, control the
sequence, timing and manipulation of his material.
The projected image can be as large as necessary
for all the audience to see.
The projected images are both seen exactly the same by the students and the
teacher.
The teacher can write information with ease or to show prepared
transparencies.
It is easy for the students and the teacher to create their own materials.

13. Overhead
Projection
Techniques
You can show pictures and diagrams using a
pointer on the transparency.
Use felt pen or wax-based pencil to make points
on the transparency.
You can control the presentation by covering the transparency using a sheet of
paper.
You can superimpose additional transparencies sheets as overlays on a base
transparency.
You can show three-dimensional object from the stage of the projector.
You can move overlays back and forth across the base in order to rearrange
elements of diagrams or problems.
You can simultaneously project on an adjacent screen other
visual materials like slides or motion pictures.
Effective Use of
the OHP

14. Effective
Use Of
OHP
Stand off to one side of the OHP and face your
students.
Place your OHP to your right if you are a right
handed.
Don’t talk to the screen. Face your students.
Avoid too large tables, come up with graphic presentation.
The presentation must be readable from afar.
Use simple colors to add effective emphasis.
Don’t read your text.
Progressive
Disclosure
Techniques
Avoid too much text.

15. Progressive
Disclosure
Techniques
Place a sheet of paper over the
transparency and move it down to
expose succeeding lines of type.
Attach strips of opaque paper to the sides of the mask in order to
cover portions of the transparency image, and then flip the strips to
expose image.
Place an opaque sheet over the transparency containing a cutout slit
which exposes lines or copy area in sequential order as it is moved
down or across the copy.
Overlaying
Techniques

16. Overlaying
Techniques
After making a sketch of the content for the
transparency, decide which part will be the base
and which will be used for each overlay.
Prepare a master drawing for each separate part.
Make register marks in two corners of each master that match marks previously
put on the sketch.
Prepare the transparency from each master.
Mount each transparent sheet: base under the frame, and overlays on the top
sides. Use the register marks for proper alignment.
