Hi I'm Jax, hearing, and a college student. I asked myself this question, and ended up making a list.
1. Watch Movies in ASL.
2. Watch Vlogs in ASL on youtube.
3. Start a video diary where you only use ASL.
4. Practice ASL conversation in online chatrooms.
5. Join a social ASL learning group online. For example, you could join a discord server or a fb group.
6. If you have a friend who knows ASL talk with them often.
7. Join an online ASL immersion event.
8. Hire a virtual tutor to practice ASL conversation.
9. Find a friend to plan and schedule a day together, where you will use 'no voice' and only ASL.
10. Attend a free virtual meeting/seminar that relates to ASL or Deaf Culture.
If you have additional suggestions please feel free to leave them in the comments below. I look forward to your response.
