What type of teaching aids are electronically displayed on a screen?

Projected teaching aids are designed to be displayed electronically on a screen, enhancing visibility and engagement during instruction. They often include slides, videos, and digital presentations that can all be shown to larger groups easily. This method allows instructors to present detailed information in a visually appealing way while accommodating various learning styles. Projected aids are especially effective in enhancing comprehension and retention, as they provide a dynamic visual experience that complements spoken information.

Simulated aids, while valuable for practical demonstration, typically do not involve displaying information through projection but rather through controlled scenarios or environments. Training props are physical items used to demonstrate a concept or skill but do not involve electronic display. Nonprojected aids refer to materials that do not require any electronic devices to present information, such as printed handouts or posters, moving away from the focus on electronic screens. Hence, the definition and purpose of projected aids make them the correct choice for this question.
