Instructional Strategies

Students with low vision and blindness may lack in motivation, develop slowly academically and be less assertive. These characteristics can cause frustration and stress. To help the students get the most out of their education accommodations and modifications are put in place to meet their needs.


1. Assistive Technology: allows individuals with visual disabilities to access information using visual, audio, and tactile input. For visuals, students can use talking books/audio books. For audio output the students can use braille display. Lastly braille 'n' speak can be used as a tactile output accommodation.

2. Expanded Core Curriculum: This includes skills that students with low vision and blindness may need help learning, beyond the general curriculum. They will learn orientation and mobility, functional skills, social skills, independent living, recreation and leisure, and career preparation.

3. Enlarged text/Audio text: calculated by their rate or reading, this will help students with low vision to be better able to see the words on the board and on paper/ allowing an ebook to speak back to the student.

1. Lighting:

-Have lights facing what you want to see and away from your eyes

-Altering the brightness on your computer or phone screen

2. Texture and Touch

-Differences in the floor textures and other tactile clues will help the hild feel more comfortable walking around without assistance.

3. Organization and Safety

-Having an organized environment keeps the element of surprise out of the equation. If your using throw rugs tape them to the floor, avoid smooth floor coverings, remove electrical cords from areas where you would be walking, and arrange the furniture where nothing is sticking out and keeping the furniture in the same place so that the child will feel more confident and comfortable moving around the house.
