I am in my second ASL class, planning to enter the interpreter preparation program at my college in the fall. Last semester, I received an "A" in ASL and so far, I've only gotten A's on my quizzes. However, I have so much trouble communicating out of the class room. I don't know why. The teachers and lab assistants are all deaf and used to signing with baby signers (the students). They don't (unless talking to each other) go excessively fast. However, I feel like I'm constantly asking them to repeat themselves. What's so different between reading sign during a test and reading during a conversation?[/QUOTE
You are only in your second class! A beginning class is almost always purely vocabulary, maybe they are using ASL and it is the sentence structure and well as the pure vocabulary that you don't understand. Even if they are signing contact sign or English, they still are probably using vocabulary you don't have yet. Beyond that let's say they happen to be signing in a way you understand with vocabulary you understand, their speed may be a little much. If you need to ask them to slow down, that's okay, they are all willing to help or they wouldn't be there teaching in the first place. Also, I don't know how old you are, but age plays a factor too, the older you are, the harder it is to learn. Give yourself another semester or two, and then see how you are doing.
For now, to improve, sign with as many people as you can. Go to deaf events, get together with your classmates, and, maybe, teach one of your family members to sign (the younger the better, age 10-up better if you want more conversation.) I taught my sister a lot of sign language, and we communicate with it all the time. It has helped me improve as well. Although I don't learn a lot of new signs from her, she has become skilled enough I can really practice my receptive skills. She took an ASL one class last fall, after I had been teaching her a few months, but she was bored because I had taught her almost all the signs! She will probably still take the ASL 2 class, (classes start tomorrow) because I know I can never replace a teacher, especially the wonderful deaf teacher she is going to have.
I am an ASL student as well, who threw myself into deaf events last semester, and I improved so much! Most people, (deaf and terps) think I am toward the end of interpreter training when they see me sign, yay! (I am going to be taking my 4th semester)
Anyway, good luck, send me a message anytime, and keep on signing!
