Reading Interventions for Students in Grades 3-12 With Significant Word Reading Difficulties

Area of Science:

• Education
• Psychology
• Linguistics

Background:

• Students with reading difficulties often struggle with word recognition.
• Significant word reading difficulties (SWRD) affect students in Grades 3-12, encompassing individuals with or at risk for dyslexia.
• Effective interventions are crucial for improving reading outcomes in this population.

Purpose of the Study:

• To evaluate the effects of reading interventions on students in Grades 3-12 with SWRD.
• To identify intervention features, such as instructional components and dosage, associated with improved reading outcomes for students with SWRD.

Main Methods:

• A meta-analysis was conducted on 22 studies, incorporating 208 effect sizes.
• Intervention effects were analyzed for students with SWRD, defined as a standard score of 80 or below on word reading measures.
• Subset and moderator analyses examined effects on pseudoword reading, fluency, and the impact of intervention dosage.

Main Results:

• A statistically significant, positive overall effect (g = 0.14) of reading interventions was found for students with SWRD.
• Interventions demonstrated significant positive effects on pseudoword reading (g = 0.38) and pseudoword reading fluency (g = 0.29).
• Increased total intervention hours were positively associated with improved reading outcomes (β = 0.003).

Conclusions:

• Reading interventions yield a small but statistically significant positive impact on word reading for students with SWRD.
• While interventions improve specific skills like pseudoword reading, there is a need for approaches that enhance generalized real-world reading.
• Dosage, specifically total intervention hours, is a critical factor linked to intervention success for this population.
