On the Spanish channel there is a Spanish version of Dora that tries to teach English.
As for visual cues, I loved it when the teacher would use these. Downside is, it would be limited given that hearing schools are also generally mainstream public education schools.
I have one question though - are there private deaf schools around? I am sure there are, just curious as I am already aware of the state run public deaf schools such as ASD in Little Rock.
