Expectations

I had to go over to the public library this afternoon to pick up our books for the Bread All Around Us project. I had worked with my school librarian to find the books, then to make my life easier, just did a reserve request at the library near where I live. I made it to the check-out desk with one minute to spare. The librarian found the books, and as she brought them over, she commented on the quantity. I explained that my class was studying different kinds of bread as part of our History/Geography unit this year, and that they were going to produce a podcast. Then, I shared I taught high school students with significant special needs, and so that was why the books were of a much lower reading level. In fact, many of the books were picture books. The librarian wondered if, maybe, I was expecting too much from my students. I told her that I didn't think so, and explained about the digital camera project (This Is My Life) from last year, and that the project was incredibly successful. More so than any of the staff that helped with the grant and project would have thought. I also told her about going to Microsoft.
So, are my expectations for my students too high? Maybe. But, they are living up to my expectations with the material they are producing. I see so much growth, and more independence in some of the students, particularly in using technology. I don't think my expectations are too high; what do others think?
