Tips for teaching ICT to vision impaired students
Teaching strategies in the classroom
Many vision impaired people depend on ICT as a tool for daily living. Teachers should be aware of what ICT can do to help overcome sight loss but also how to make use of ICT in their teaching to best suit the VI student's needs.
The following points can help make the classroom more user-friendly for vision impaired students.
- Avoid screen glare. Turn brightness down, but not so far that the student can't see the information. Check with them what is the most comfortable level of light.
- Have individual profiles when using computers or tablets so a VI student's accessibility settings are saved each time they log in.
- Use mobile devices which include a zoom feature so information can be displayed at the best size for the vision impaired student.
- Create a bank of MP3 files using texthelp Read&Write to give spoken instructions on how to build pages or write code. Small chunks of information are best – around three minutes each.
- Use software such as Evernote to capture audio recordings and play them back later.
Assistive technology (AT) can allow a vision impaired student to increase their access to information. Making small changes could make a huge difference to a VI student. The following items are for use by individuals, or in the wider classroom.
