ABSTRACT This study investigated changes in attitudes toward persons with disabilities among students in an introductory special education class (experimental group) and students in a general foundations of education class (control group). A multifaceted intervention consisting of information, contact, and persuasive messages was provided to students in the experimental condition during a 1 0-week course. Results indicated that students in the experimental group had significantly greater improvement in attitudes than students in the control group, as measured by the Attitudes toward Disabled Persons scale. Students in the experimental group reported that contact was significantly more influential in changing their attitudes than either information or persuasive messages.Since 1977, PL 94-142 has guaranteed students with disabilities the right to a free and appropriate public education in the least restrictive environment. For many students, the least restrictive environment will be mainstreamed classes. Although many factors influence the assimilation of students with disabilities into mainstreamed classes, one key factor is likely to be the attitudes of educators toward teaching students with disabilities.
