What is the best use of in class support?

This year I have a student who did not hear until she was 3 years old and therefore is still learning to communicate. I meet with her SLT to create specific goals and discuss her learning. This time is so beneficial for me because I have some time to sit with and specifically reflect on this specific student. This student receives some support with a Teacher aide either an hour or half hour a day. Recently I have been thinking about the best use of this time. Some days the student and TA work in class and other days they work in a separate room. I was thinking about whether it would be more beneficial for me to spend that time working 1:1 with this student. Throughout the rest of the day majority of the work is very hard for her and even though her activity is differentiated I still feel she doesn't have the time to work at her own pace or level. Next week I might alternate days where I work with the one student and the TA works with the class. I feel that because I only have 10 students in my class this might be possible and I believe that this will really accelerate this students learning and confidence in the class.
