The Adaptation of Materials for Students with Visual Disabilities

10 August, 2020
Students with visual disabilities have difficulties when it comes to accessing academic content. Therefore, it's important to adapt materials to their needs.

Schools have the obligation of adapting materials for students with visual disabilities. That way, these children can access the academic curriculum and learning content.

This is a basic measure for meeting the specific educational support needs of students that experience significant visual difficulties.

“Just because a man lacks the use of his eyes doesn’t mean he lacks vision.”

– Stevie Wonder –

What is a visual disability?

Visual disabilities refer to the presence of significant functional deficiencies when it comes to sight. In other words, this concept includes different types of serious vision problems. So, according to Natalie Barraga, we can distinguish between:

  • Total blindness: This type of vision only allows individuals to perceive light.
  • Partial blindness: What little vision a person has only allows him or her to perceive blurry shapes or blobs.
  • Low vision: Individuals experience important deficiencies when it comes to visual acuteness. However, they can see objects that are a few inches away. Therefore, they require adaptations to carry out a variety of day-to-day activities.
  • Limited vision: The visual deficit isn’t excessively serious, meaning individuals aren’t unable to perform day-to-day activities. However, they do require certain simple adaptations in order to do so.

The adaptation of materials for children with visual disabilities

Children with visual disabilities need adapted materials to their special educational needsThis guarantees them proper access and reproduction of the information they must learn. These adaptations can take place using a variety of resources, including the following:

Materials for students with visual disabilities: Enlargement

Enlargement consists of increasing the size of a document in order to facilitate access to specific material. The presentation should be clear and have good contrast with a letter-size that’s not too big.

This technique is useful only in specific cases, given that it’s best to use the adaptation possibilities that computers offer. That way, we can choose the most legible fonts for students with visual disabilities. And, at the same time, erase backgrounds and minimize poor contrasts.

Materials for students with visual disabilities: Recordings

Recordings are an excellent way to adapt academic materials for students with visual disabilities. This involves the oral transcription of materials so that children can access them by audio.

However, the main problem with this method is that it’s not possible to record everything. For example, content having to do with math, physics, chemistry, etc.

Materials for students with visual disabilities: The braille system

The braille system is a writing system that consists of raised points. Each letter or number is represented by a different combination of 6 points within a cell. Adapting materials for children with visual disabilities involves transcribing them to braille so that children can read them by touch

Materials for students with visual disabilities: Tactile images

Another way to adapt materials for children with disabilities that affect their vision is through the use of tactile images. These tools allow students to use their sense of touch in order to have an overall image of information.

The Adaptation of Materials for Students with Visual Disabilities

  • Size: Children should be able to access all of the information with their two hands and be able to discern it easily.
  • Simplicity: It should be monothematic and include different textures and heights.

Other necessary adaptations

Besides the adaptation of visual materials, it’s also important to adapt a child’s environment. That means implementing a series of measures in regard to physical changes in the classroom and academic institution. For example:

  • Providing students with visual disabilities with a desk that’s large enough for them to use their adapted materials.
  • Organizing elements in a fixed and stable way, and always letting students know of any changes.
  • Eliminating architectural obstacles and barriers that impede accessibility.
  • Having proper lighting
