Running Head: Meta-Analysis on Math Interventions2research that shows that cognitive strategies and direct instruction models were the most effective interventions. Gersten et al (2009) states that “they examined interventions in the areas of preparatory mathematics, basic skills, and problem-solving strategies. They found interventions in the area of basic skills to be most effective” (p. 1204). Gersten et al also found that “direct instruction and self- instruction were found to be more effective than mediated instruction” (p. 1204, 2009). When using math interventions as an instructional aid it allows the students to have a higher chance of comprehending the math concepts and lessons. These interventions are able to help students understand and comprehend what the lesson needs them to. They help the students learn through instructional practices and activities that have the ability to enhance math, which will allow students to achieve their math goals.
