Question

Which one of the following is a non-projected visual aid?

• A. Diorama
• B. Slides
• C. Puppet show
• D. Video

Hint:

To distinguish between projected and non-projected aids, ask yourself:
"Do I need a projector, screen, or electronic monitor to view this?"
- Yes $\implies$ Projected Aid (Slides, Videos).
- No $\implies$ Non-Projected Aid (Dioramas, Models, Posters).

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Extension teaching aids are classified by how learners perceive them (audio, visual, or audiovisual) and how they are displayed (projected vs. non-projected).
- Projected aids: Require light, projection screens, or electronic devices to display the image or message (e.g., overhead projectors, slides, film strips).
- Non-projected aids: Do not require projection equipment and can be viewed directly under normal ambient light (e.g., posters, charts, models, specimens, dioramas).

Step 2: Detailed Explanation:
Let us analyze the options:
- (A) Diorama: A diorama is a three-dimensional, miniature model representing a real-life scene (such as a model village, crop rotation layout, or soil conservation farm).
It is viewed directly by learners without any projection equipment.
Therefore, a diorama is a classic non-projected visual aid.
- (B) Slides: Slides require a slide projector or digital projector to display the image on a screen.
Therefore, they are projected visual aids.
- (C) Puppet show: A puppet show is primarily categorized as an activity or dramatic aid. It involves motion and sound, making it an audio-visual drama method.
- (D) Video: Video involves both moving images and sound displayed through electronic screens.
Therefore, it is classified as a projected audio-visual aid.
Thus, "Diorama" is the correct non-projected visual aid.

Step 3: Final Answer:
The correct option is (A).
