Research on Efficacy
Recent research continues to document the effectiveness of Direct Instruction. These studies confirm the accumulated findings of decades of research showing that students taught with DI have higher achievement scores and stronger growth rates than students studying with other curricula.
Positive findings regarding DI appear with students with different learning histories: with middle class high achieving students, with high risk students, with general education students, and with special education students.
Positive findings are documented for students with different racial-ethnic backgrounds: in schools that are predominantly African American, those with substantial numbers of Hispanic students and those with large numbers of non-Hispanic whites.
