Deaf events are primarily times of social relaxation for members of the Deaf community, and the intrusion of students into particular events may be unwelcome. The involvement of teachers in the activities of local Deaf clubs would help teachers to maintain these contacts, and promote awareness of events appropriate for students to attend. Focus on the signer's face, not the hands. Don't break eye contact while in a signed conversation. Your teacher may stop to repeat information because you do not nod to indicate you are following along.
Listeners have very active roles in signed conversations.
Participate as much as possible by adding comments, agreeing or disagreeing, etc. The more you participate, the more you will retain what you learn. Don't worry about mistakes. They are part of the learning process. Try not to worry about a sign you missed.
