These two related papers provide information on teacher attitudes toward black dialect use in the classroom and the measurement of such attitudes. The first paper reports on data from 176 administrators, counselors, teachers, and student teachers, revealing significant relationships between a teacher's definition of black dialect, attitudes toward black dialect, and race of teacher. The second paper describes the steps taken to refine and improve a language attitude inventory (LAI) so that it could be used to describe and to make inferences about teachers' attitudes toward the use of black dialect in the classroom. The two versions of the LAI and a bibliography on teacher attitudes and dialects are provided. (RL)
