What type of educational aid is best described as visual tools like videos and charts?

The best choice is visual aids, as they specifically refer to resources that enhance learning through sight. Visual aids include tools like videos, charts, graphs, diagrams, and images, which help to illustrate concepts and make the information more accessible and engaging for students. These tools can simplify complex ideas and aid retention by providing a clear and memorable association with the material being taught.

While physical aids refer to tangible objects used in the teaching process, they may not strictly be visual and could include items like mannequins or hair products. Auditory aids focus on sound and include tools such as lectures or audio recordings, which do not leverage visual elements. Digital aids pertain to online resources or software but do not exclusively encompass visual elements, as they can also include audio and text formats. Therefore, visual aids are the most accurate description of tools that primarily use sight to support education.
