Munson, S. M. (1987). Regular education teacher modifications for mainstreamed mildly handicapped students . The Journal of Special Education , 20 (4), 489–502. https://doi.org/10.1177/002246698602000409

Twenty-six regular education teachers were interviewed about their perceptions of modifications for students with mild handicaps. Results indicated that teachers made more typical modifications (format of directions, test administration procedures, etc.) than substantial modifications (altering difficulty) for these students. A negative relationship was found between teaching experience, teacher age, and class size and the number of modifications reported.
