The role of the teacher is to encourage all attempts at reading, writing, and speaking, allowing students of varying ability to experience the different function and use of literacy activities. Teacher interactions with students with disabilities build on students' knowledge as they develop literacy skills. Teachers use a variety of methods of communicating with students by asking questions, labeling objects and experiences with new vocabulary, and offering practice to help students remember and generalize new concepts and skills (Whitehurst, 2003). Teaching staff plan activities so that students "have opportunities to integrate and extend their literacy knowledge by reading aloud, listening to other students read aloud, and listening to tape recordings and videotapes in reading corners" (Gunn, Simmons, & Kameenui, 1995, 5). Also, staff teaches students how to use the materials in their environment to promote interest and use of literacy materials throughout the classroom (Gunn, Simmons, & Kameenui, 1995). Another strategy involves staff members intentionally making mistakes to demonstrate editing and revising (Goodman, Bird, & Goodman, 1991), modeling for children the importance of making mistakes while demonstrating the writing process.
