ILAB: Independent Laboratory Access for the Blind
Purpose
•
•
•
•
The goal of this project is to raise the expectations of blind
and low vision students as well as educators, in order to
encourage them to consider pursuing careers in Science,
Technology, Engineering, and Mathematics (STEM)
professions.

Student Suggestions for Working in the Laboratory
•
•
•
Sit near front of the
laboratory
Orient self to lab before
term begins with teacher’s
assistance
Develop personal method
to take lab notes
ILAB: Independent Laboratory Access for the Blind

ILAB and Vernier Collaboration
• Visit to Vernier (March 2010)
• Worked with Vernier Software engineers to
incorporate JAWS accessibility into future
LoggerPro versions
• Received input from JAWS users to Vernier
Software engineers
• Discussed LabQuest and speech accessibility
ILAB: Independent Laboratory Access for the Blind
JAWS: Job Access With Speech
• Converts written text to speech via computer
• Navigates data tables
• Starts and ends experiments
• Reads labels of Cartesian graphs
• Accesses statistical info
• Customizable using special JAWS script files

JAWS with Vernier Probes
•
•
•
•
Every Vernier Software and Technology Company
probe, analog and digital, is now JAWS-compatible
All analog probes in the chemistry, physics, earth
science and biology allow BLV students to obtain realtime data readings.
All balances distributed by Vernier are JAWS-compatible
and provide real-time measurements
More JAWS-compatible digital probes are being
developed

Science Activities for the Visually Impaired/Science
Enrichment for Learners with Physical Handicaps
provides a multi-sensory approach to learning
Originally developed to meet the science learning needs
of students in grades 3-8, but has found significant
application in high-school classrooms as well
Tools include balances, graduated cylinders with floats,
thermometers, sorting trays, and syringes
•
Now part of the Full Option Science System
•
Detailed information easily found on the internet

Other ILAB Tool Mainstream
Applications
SALS can aid in lecture demonstration activities both for
blind and sighted students.
Talking Vernier probes can assist demonstrations in large
lecture hall settings.
ILAB tools and techniques can benefit other student groups:
• Students with learning disabilities may learn with less
difficulty when there are different approaches available to
gather and process data
• Students with Attention Deficit Disorder may enjoy a
novel approach to science experimentation
• Deaf and blind students can receive a more independent
learning experience when ILAB tools are coupled with
vibrational output
ILAB: Independent Laboratory Access for the Blind
Design of Experiment
•For internal control, the experiments are randomized as to
when the participants can and cannot use the ILAB tools
•All data will be used to construct a case study for each
participating school
•The teacher along with consultation from ILAB team
members will determine where ILAB tools are necessary
for the Physics, Chemistry and Biology curriculums
•Conduct SAI (Scientific Attitude Inventory) II surveys preand post- school year
•All experiments are video recorded
•The videotaped analysis will be conducted at the end of
the school year

Our vision is to promote a barrier-free learning
environment for BLV students interested in the science,
technology, engineering, mathematics (STEM) fields of
study. Our mission is to eliminate the barriers that hold
back BLV students from learning by providing them with
the latest technology that will give them a hands-on
learning experience in the STEM fields.
