      Projected and non-projected aids have their own advantages and disadvantages. Here is a comparison of different kinds of projected and non-projected aids:

      Non-projected aids:

      • Advantages: abundant and easily obtainable, very useful in places where there is no electricity, and in low-budget situations, not much artistic ability on part of extension workers is required, useful in small group situations, and many non-projected aids can be converted into projected aids.
      • Disadvantages: limited visibility, not suitable for large groups, and not suitable for use in dark or semi-dark conditions.

      Projected aids:

      • Advantages: suitable for use in dark or semi-dark conditions, suitable for large groups, and can be used to magnify images for better visibility.
      • Disadvantages: require electricity, can be expensive, and may require technical expertise to operate.

      Overall, the choice of whether to use projected or non-projected aids depends on the specific teaching situation and the resources available. Non-projected aids are more suitable for small groups and low-budget situations, while projected aids are more suitable for large groups and situations where visibility is a concern.
