Especially in the education of students who are deaf or hard of hearing, teachers' practical knowledge storage is almost never measured. The Survey of Practical Knowledge was used to compare the practical knowledge storage of deaf and hearing teachers of these students. Surveyed were 48 deaf and 115 hearing individuals at the preservice and in-service experience levels. Practical knowledge storage was defined as images, rules of practice, and practical principles. Results indicate that deaf teachers tend to view students as equals but are more likely to emphasize control over classroom behavior than hearing teachers. Hearing teachers tend to stress efforts to engage students in subject matter by providing variety and relating it to life experiences. Given the trend toward high-stakes testing of teachers, further research is encouraged on role differences between deaf and hearing teachers working with students who are deaf or hard of hearing.
