This app ($1.99) will pronounce any word that is typed in on a qwerty keyboard (color coded qwerty available for younger children). Assuming kids can type in a word accurately, this could be very helpful. For iPhone, iPod touch or iPad. Think of it as an e-reader for unknown words...would be very helpful to ELLs and students with word recognition difficulties because it pronounces the word.
iPad/iPhone--App for recording student behavior. Free verson allows you to follow 5 students on 3 behaviors.
Pro-version is customizable and probably worth the money--good reviews on Teacher's Assistant Pro.
I might try the free version first and then upgrade.
