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.

Techniques

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

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.

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

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.
