Microsoft's Mouse Mischief seems like it would be a perfect tool in Deaf and Hard of Hearing Classrooms. Because it's a collaborative tool that is visual in nature, a teacher can give the entire lesson via a Mouse Mischief exercise.
Please take a lot at the video below and do not hesitate to contact me with any questions.
I had a chance to view the website recently. Unfortunately I could not download this application to try with my students yet because I don't have administrative privilages on my laptop...duh. I think technology is moving much quicker than my district would like to accommodate for at times. Thank you for sharing the info. It does look like something I would use upon occasion with students in a classroom and accessible for DHH.
The video below is great...this wasn't displaying on my computer at work, another kink I face. But, I couldn't get the caption to work (I appreciate you making the option available though).
