This study asked 527 students enrolled in a basic communication course to evaluate the efficacy of a speech lab in relation to speech requirements stipulated by their instructors. In addition, the researchers examined the scores of 435 student speeches to determine if students who visited the lab earned higher grades compared to students that did not visit the lab. Results showed that (a) most instructors require their students to visit the lab before at least one speech, (b) the vast majority of students perceive the help they receive in the lab to be very useful, and (c) students who visit the lab prior to their speeches earn significantly higher grades on speeches than those who do not visit the lab.
