Analyzing the Use of C-Print Mobile Technology in STEM Lab Settings across
Multiple Postsecondary Sites Michael Stinson & Lisa Elliot
National Technical Institute for the DeafRochester Institute of Technology
NSF JAM, June 7, 2011
Challenges
• Traditional classroom captioning services provided on a laptop in laboratory settings:– May result in deaf students missing essential
information– Are cumbersome because it is difficult to carry and
read an open laptop while moving around the laboratory
– Take up too much space in work area
Goals
• Expand the venues in which the classroom captioning service (with C-Print mobile) is used from RIT to several other postsecondary settings
• Evaluate the extent to which the service aids students’ access and learning in STEM labs

• Total n= 37
Benefits• Size
– It is small and does not take up space that is needed for lab work.– The best thing was the phone doesn't take up all of the work space which we need for our
labs. It is small and easy to carry and easy to read!
• Portability – I was able to carry it around the lab with me, to hold it in my hand while the instructor is
talking, and was able to scroll up and down to see what was previously said. – The best thing about using C-print on the mobile device is that I can carry the device with me
when my instructor is in the front of the classroom, not near my lab table, whenever I need a question.
• Usability– It was easy to carry around if I needed to, and easy to connect! I could connect it myself and
not have to wait for the captionist to stop typing and then connect—less missed information. – It was easy to read, especially white on black makes it easier. The print was big enough for me
to sit back and read.
