Delivering Math interventions to Maximize Student Outcomes: Meta-Analysis Findings

This session is from the NASP 2021 Annual Convention

  • PMD: 1,3
  • Skill Level: Intermediate
  • Session 4: Assessment and Intervention in an RTI Framework

Learner Objectives

This session will help participants…

  1. learn results examining the effectiveness of math interventions and moderating effects of treatment intensity.
  2. learn how intervention strength can relate to student math outcomes and recommendations for intensifying intervention components.
  3. learn recommendations for delivering more feasible and equitable math interventions.


When delivering supports within RTI, interventions must be intensified to meet student needs while ensuring they are feasible, equitable, and resource efficient. Treatment strength is an understudied, yet important intervention component. The purpose of this presentation is to provide updated findings and recommendations on math interventions targeting whole number computation and discuss moderating effects of treatment strength (e.g., duration, frequency), implementation components, and dependent variable aspects (e.g., criteria). Research and practice implications will be provided.
