Which of the following is an electronic instruction aid?

• A. Dry erase board
• B. PowerPoint Presentation
• C. Overhead Transparencies
• D. YouTube video

Answer: (B)

An electronic instruction aid is a tool that delivers instruction using electronic technology. A PowerPoint Presentation fits because it’s software used to build and display a sequence of slides on a computer, often projected to a group. It centralizes content, adds visuals, and can include embedded media and notes, making it a practical, repeatable way to guide a lesson electronically. A dry erase board is purely a physical surface for handwritten content, not electronic. Overhead transparencies are physical sheets used with a projector; the transparency itself isn’t electronic. A YouTube video is electronic media, but it’s a standalone resource rather than the structured instructional tool used to present a lesson in a controlled sequence. PowerPoint provides the organized, electronic format that fits the idea of an electronic instruction aid.
