Teachers' perceptions of student behaviors were examined to explain teachers' attitudes toward their students with and without learning handicaps. The study involved 44 intermediate-grade teachers who had students with learning handicaps and nonhandicapped students in their classrooms. Teachers' attitudes were measured with a four-question survey, and their perceptions of students' behavior, achievement, and personality were obtained through use of the Teachable Pupil Survey. Results indicated that students whom teachers perceived as exhibiting less ideal student behaviors were more likely to be rejected by teachers, without regard to disabilities. Findings imply that the handicapped label does not influence teachers' attitudes as much as the teachers' perceptions of the students' behaviors do. (Contains 28 references.) (JDD)
