Objective: To outline a methodical approach to describing the visual world to blind children
Both the teacher and the blind child suffer from limited time; you cannot describe everything in detail to the child. It is therefore important to view description as an absolutely vital but limited resource.
First, ask why a child needs to know about what you can see. The purpose of knowing will help you to edit your description: Any description of a physical environment or picture is capable of being utilized for a wide variety of purposes. If you look outside your window you will see a panorama, which might be described in terms of its architecture, biology, history, or social purpose. So your first question is “Why am I describing this?”
We need to decide “what” to describe, limiting ourselves to those features relevant to enhancing the child’s experience or enabling her to complete a given task.
Description should be concrete, and as numeric as possible; that is, dimensions in numeric value and proportionality compared to tactile experience (few children will have climbed from the foot to the roof of a building). For example, “What I am seeing is much wider than it is long, like your sleeping room.” Description should pay attention to chronology (what happened first, second, third) and ranking (e.g., biggest to smallest).
Congenitally totally blind children will only understand color as a socially acceptable concept (e.g., the sky is blue, the grass is green), such that she might question the statement, “The sky is yellow, the grass is red.”
It is extremely important in dynamic social situations to describe carefully the facial expressions of peers reacting to a conversation, not jumping to crude assessments such as “angry” when what you might mean is “puzzled;” tell the truth, but be accurate, as this is part of a child’s learning what reaction her behavior and speech provoke.
Models are better than tactile drawings.
Use class time to encourage different children to describe the same thing; this will help the children and their blind peer to learn that, in spite of numerical values, different people see the same thing in different ways.
Guidelines for writing descriptions for STEM graphics (diagrams, charts, graphs, etc.) and for the images and graphics associated with assessments are available from the National Center on Accessible Media.
