Meta-analysis of targeted small-group reading interventions

Area of Science:

• Educational Psychology
• Literacy Studies

Background:

• Small-group reading interventions are widely implemented in educational settings.
• Key components contributing to their effectiveness remain underexplored.

Purpose of the Study:

• To meta-analyze existing research on small-group reading interventions.
• To identify factors influencing the efficacy of these interventions.

Main Methods:

• A meta-analysis was conducted on 26 studies yielding 27 effect sizes.
• Intervention characteristics, student age, group size, and duration were analyzed.

Main Results:

• A moderate overall effect size (weighted g=0.54) was found for small-group reading interventions.
• Targeted interventions showed higher efficacy (g=0.65) compared to comprehensive programs (g=0.35).
• Interventions were more effective for elementary students (g=0.64) than older students (g=0.20).

Conclusions:

• Small-group reading interventions are effective, particularly when skills are targeted.
• Intervention design and student age are important considerations for maximizing impact.
• Further research should refine understanding of optimal intervention components.
