Understanding Types of Teaching Learning Materials (TLM)

Teaching Learning Materials (TLM) are tools used by teachers to help students understand concepts more easily. These materials can be classified into different types based on how they are used or experienced.

Let's examine the pairs given in the question:

• Projected Aids: These are materials or equipment that project an image onto a screen or surface. Examples include overhead projectors, filmstrips, slides, and magic lanterns.
• Non-projected Aids: These are visual aids that do not require projection. They are directly viewed. Examples include charts, posters, pictures, maps, models, blackboards, and diagrams.
• Experimental Aids / Activity-Based Aids: These involve direct experience or participation by students. Examples include experiments, demonstrations, field trips, role-playing, and simulations.

Analyzing the Given Pairs

Let's look at each pair provided:

I. Projected aid – Magic Lantern

• A magic lantern is an early type of image projector. It uses a light source, lenses, and translucent images (slides) to project a magnified image onto a screen.
• Because it projects an image, it is classified as a projected aid.
• This pair is Correct.

II. Experimental aid – Photographs

• Experimental aids involve hands-on activities or direct experiences.
• Photographs are static images. While they can be used in an experiment or as part of a demonstration, they themselves are not experiments or activities. They are typically non-projected visual aids.
• This pair is Incorrect.

III. Non-projected aid – Field trip

• Non-projected aids are visual materials that don't require projection, like charts or models.
• A field trip is an educational excursion to a place away from the normal classroom environment. It provides students with direct, real-world experience.
• Field trips are classified as experimental aids or activity-based aids because they involve direct experience, not as non-projected visual aids like posters or charts.
• This pair is Incorrect.

Conclusion

Based on the analysis, only the first pair, "Projected aid – Magic Lantern," is correct.

Therefore, the correct statement is Only I.
