The third factor is teachers’acceptance of the practice. Successful adoption of innovative practices occurred when it was consistent with teachers’ beliefs or teaching style (Klingner et al., 2001; Vaughn et al., 2000), when the practice helped the most difficult-to-teach students, and when teachers received supportive training (Gersten et al., 2000). Because learning novel teaching practices places new demands on teachers, they will not sustain their use of innovative practices unless they see benefits for students (Gersten et al.; Klingner et al., 2001).
