This study examines the extent to which deaf students' perceptions of their
teachers' effectiveness and ease of communication in the classroom are rel
ated to the teachers' sign skills. Thirty-three faculty, teaching a variety
of courses at the National Technical Institute for the Deaf(NTID), were ra
ted on "teaching effectiveness" and "communication ease" by their students
over a 2-year period. Faculty sign proficiency was evaluated independently
using the Sign Communication Proficiency Interview(SCPI). Results indicate
a moderate relation between students' perceptions of communication ease and
teaching effectiveness, and a weak relation of these two variables to the
teachers' assessed level of sign skill. The data also show that the student
s could clearly differentiate three levels of teacher sign skill in the cla
ssroom. Results are discussed in relation to the component parts of effecti
ve communication from the perspective of students in the classroom.
