How can I help a student who is blind or has low vision make measurements in a science lab?

DO-IT Factsheet #39

Students who are blind can participate in lab-based or other hands-on activities side by side with sighted students if simple accommodations are in place. Often they will need accommodations to make measurements in a lab activity, since standard rulers, dials on stoves or hot plates, syringes, balances, and many other measuring devices require vision to read. Two simple strategies that can be used for students who are blind are teaming and making equipment tactile.

First, team students who are blind with students or groups with complementary capabilities. Be sure that all students in a group have opportunities to make contributions to projects. Help maximize individual participation by allowing students to decide roles within their group and assessing them, in part, on how well they fulfill those roles. Determine the role for a student who is blind first, since the possibilities may be more limited for him/her than for others, and make sure this student is actively involved in the choice to promote self-advocacy and social skills.

Second, make or adapt items used for measurement and display so they are tactile. If looking at a line on a ruler or graduated cylinder will allow a student to make accurate measurements, then raised lines and raised or Braille numbers can make that equipment accessible to the student who is blind.

Below are specific strategies that a teacher has used to accommodate students who are blind in his science classroom:

These examples demonstrate that creative use of inexpensive supplies and a commitment to the full participation of all students can make the experiences of a student who is blind in your class a positive one. Regarding all accommodations, ask students to provide insights on strategies that have worked in the past. Remember that students with disabilities are or should be becoming experts on their disabilities and accommodation needs.
