What best describes the use of tactile modeling for students with severe visual impairments?

The correct choice captures the essence of tactile modeling, which is a hands-on approach that allows students with severe visual impairments to learn through touch. By having the student feel a demonstrator's actions or the relevant parts of the body or objects involved in an activity, they can better understand spatial relationships, movements, and actions that they might not be able to perceive visually. This method is effective because it provides a direct sensory experience that can help the student internalize and replicate those actions, fostering independence and skill development.

The other options, while each beneficial in their own contexts, do not specifically align with the tactile modeling approach. Audio cues and verbal instructions, although helpful for providing information and guiding students, lack the hands-on element crucial for tactile learning. Visual aids, typically designed for students with some level of sight, do not cater to the needs of those who are severely visually impaired or blind, as they rely on visual perception rather than tactile exploration. Therefore, tactile modeling stands out as a direct and relevant technique for facilitating learning through touch.
