I teach special education students. THey love Read 180 and are doing great. My one complaint is with the SRI testing set up. I know it is an intuitive test that adjusts based on student answers, however, for my special education students, especially the ADHD kids, not having any idea how many more questions they will have is a big issue and it causes them to get frustrated and give up.
I have found that unless my para sits down next to certain students to make sure they don't get frustrated, they will just answer anything to finish. They really need a count down of some kind, like the % done on a computer download.
At least I have figured out why some students SRI was going down even though their work in class was improving.
