Non-projected teaching aids are instructional materials that do not require any electronic devices or projection equipment to be used in the classroom. Examples include printed materials like charts, posters, handouts, and models, as well as real objects or physical demonstrations. These aids facilitate learning by providing visual, tactile, or auditory experiences that enhance understanding and retention of the subject matter. They are often used to support various teaching methods and engage students in a more interactive way.
projected aids
A non projected aid used in teaching would be a chalkboard, textbook, or audio with no video capabilities. A projected aid is a visual aid such as a computer with graphics and television.
All audio aids are non projected e.g white board soms visual are included, those in which we do not reflection. projected aids are sophisticated in nature and complex as well.
Projected media requires electricity in order to function. On the other hand, non projected media does not require electricity in order to work.
Difference between projected and non- projected instructional aids
Projected media is media that is projected onto the wall or a screen. Schools use projected media as a teaching tool.
projected visuals need electricity while non-projected visuals do not require electricity to project images on a screen

Projected resources refer to the estimated quantities of natural resources that can be economically extracted in the future based on current technology and market conditions. These estimates are often based on geological surveys and modeling. Non-projected resources, on the other hand, include those that are known to exist but cannot be quantified or economically extracted at present, often due to technological, economic, or regulatory constraints. Essentially, projected resources are viable for extraction, while non-projected resources remain uncertain or uneconomical.
