Exploring Heterogeneity in Mathematics Intervention Effects Using Meta-Analysis

AIR conducted a systematic review and meta-analysis to examine the heterogeneity in mathematics intervention effects by synthesizing 25 years of randomized experiments of interventions designed to improve mathematics achievement in Grades K-12. The goal of this project was to better understand the conditions and contexts for why one study may find that a mathematics intervention works while another study on the same intervention may not find that it works.

What Works Clearinghouse Statistics, Website, and Training (SWAT)

The What Works Clearinghouse (WWC), the standard bearer for effectiveness research in education, conducts its work through multiple contracts. AIR holds the SWAT contract, which provides coordination vitally important to the success of the WWC by centrally updating WWC policies and procedures, providing training and technical assistance, conducting quality checks of WWC products, supporting users through a website and Help Desk, and communicating with one voice to WWC contributors, users, and stakeholders.

The Development of Gender Stereotypes About STEM Abilities: A Meta-Analysis

AIR is conducting two meta-analyses by synthesizing more than 25 years of empirical research across the world to study the origins of beliefs and motivational processes that could potentially limit the full participation of girls and women in science, technology, engineering, and mathematics (STEM) fields.

A Systematic Review and Meta-Analysis of Interventions to Decrease Cyberbullying Perpetration and Victimization

The goal of this project was to synthesize the literature on the effects of prevention programming on reducing cyberbullying perpetration and victimization. The search yielded over 50 studies and 100 effect sizes. The results of the meta-analysis revealed that programming is moderately effective in reducing cyberbullying.
