Waiting is a tiring game!!

Right now, nothing much is happening. I am playing the waiting game. My next step in my project is to video tape students using the assistive technology in the classroom and taping myself, programming the different devices. Right now, I am waiting for permission for parents/guardians to tape. I have gained permission from one parent already, so I am trying to schedule a time to go over to tape. The student is at the high school next door so it shouldn't be too hard to get away to tape a bit. The parent has also given me permission to borrow his device (it is the student's personal device, not the school district's) so I can tape the programming. I should be able to tape him by the end of this week then take his device home this weekend and tape. The other student I would like to use is a little harder to get in touch with. She lives in a group home here in Cola, but mom lives in Greenville. I am debating on whether to just tape the programming of her device and not worry about having her on tape. A teacher here at my school has a student who has special needs and has offered to let me use him anytime I need to. This would help because I wouldn't have to worry about getting everything done during school hours. The only problem is he doesn't actually use the devices in the classroom, so it wouldn't be very authentic. I'm trying to weigh my options: is it better to go with convenience or authenticity?? If I went with the convenience I would of course make a note on my final project (the website) that the student used in the taping does not use the device on a daily basis. What do you all think?
