Lifeprint has college-level ASL 1 and ASL 2 modules developed by Dr. Bill Vicars. This website is filled with information related to interpreting, Deaf culture, fingerspelling practice, etc.
Spread the Sign is a free video sign language dictionary for ASL and other signed languages. There is also a free app available in the Apple App Store and Google Play store. I highly recommend that all students and teaching assistants download this app.
DCMP is the Described and Captioned Media Program managed by the National Association of the Deaf. It is free to create an account but does take a few days to become active. Their YouTube channel has a variety of resources including vocabulary building videos (~30 minutes each) related to: English, Psychology, Math, Science, Government, and Computers. (Note: Some of these signs are old variations that were used and may have changed.)
The Daily Moth is a news source produced in ASL by a former graduate of the Florida School for the Deaf and Blind. This is excellent practice for students because (1) it is all current events, (2) the host provides exposure to fingerspelling, and (3) a transcript is provided for all videos which can be used to compare comprehension.
DVTV is a YouTube-like site for ASL users. Students can be exposed to different signing styles, regional sign variations, and current topics in ASL.
Video Library for ASL Students at the University of Florida
If you have a GatorLink username and password, you have access to a variety of videos filmed by former UF ASL instructor Dr. Mike Tuccelli. Videos include information related to Deaf culture, the psychology of deafness, storytelling, heavy fingerspelling practice, and signing styles ranging from Signed Exact English, ASL, and DeafBlind communication methods (Tracking). Special thanks to Dr. Judy Shoaf, the Director of the Language Learning Center at UF, and former Signing Gators President Devon (Mims) Otero for converting VHS to this electronic source.
