approaches used to teach the TTSS, the knowledge students are demonstrating
through the use of their TTSS, and the context in which the TTSS was being
implemented. Data for the project was collected through observations that
embedded the use of a TTSS, interviews with the developer of the TTSS, and a
collection of artifacts that included pictures of the system and I.E.P. information
that was relevant to the TTSS. Additionally, teachers completed a student
description survey to provide demographic and historical information about their
target students.
Data analysis was conducted on each case individually. Following a detailed
procedure, each case was coded independently by two researchers who then met to
engage in consensus coding to discuss any differences in codes, agree on code
names, and to identify final themes. At the completion of the study there will be 12
student participants; however, this article will present the findings from just one
case.
The student participant "S" was a five-year-old Caucasian-Hispanic female.
She was diagnosed with CHARGE syndrome in addition to severe developmental
delays. Her bilateral sensorineural hearing loss was in the moderate-severe range,
but within normal limits when using her hearing aids. She experienced bilateral
retinal colobomas that resulted in 20/260 uncorrected vision in addition to a field
loss. She expressed through emerging speech and single manual signs. She was
