ECR Hub: Advancing the Long-Term Potential of Fundamental Research

Contacts: David MillerDanielle FergusonLarry V. Hedges
Population: Early childhood through Adults
Topics: Education; Synthesis MethodsKnowledge Translation; Alternative Review Types

This five-year resource center is a partnership with the National Science Foundation to extend the reach of its existing investments and build career opportunities related to fundamental STEM education research. The STEM Education Core Research (ECR) Hub will support NSF’s ECR program, which funds curiosity-driven and use-inspired fundamental STEM education research.

Consequences of Selective Reporting Bias in Education Research

In systematic reviews and meta-analyses, selective reporting can create at least two types of biases: publication bias and outcome reporting bias. AIR is developing two selection models that will simultaneously account for selective reporting and effect size dependencies when conducting a meta-analysis.

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

The What Works Clearinghouse (WWC) is a leading federal source of evidence-based information about education programs, policies, and interventions that show promise for improving student outcomes. AIR holds the WWC Statistics, Website, and Training (SWAT) contract whose focus is on updating WWC policies and providing training and support.

The Effects of 5E-Based Interventions: Systematic Review and Innovation Through New Meta-Analysis Methodology

Contacts: Joshua PolaninRyan Williams
Population: Early childhood/Pre-K
Topic: Education; Synthesis MethodsMeta-analysis; Systematic Literature Review

The Engagement, Exploration, Explanation, Elaboration, Evaluation (5E) instructional model was first introduced in 1990 and is ubiquitously used in STEM education. Using a rigorous systematic review methodology, AIR is identifying all published and unpublished studies that use a high-quality study design to evaluate the effects of the 5E instructional model and its derivatives.

Qualitative Development of Patient-Reported Outcome Measure for Temporomandibular Joint Disorders

Contact: San Keller
Population: Adults (ages 18+)
Topic: Health; Synthesis Methods

AIR conducted a literature review and focus groups to identify a reliable and valid Patient-Reported Outcome Measure to document health outcomes for patients with Temporomandibular Joint Disorders (TMD). This project is part of an outgrowth of efforts by the FDA to improve therapy for TMD through incorporating patient input into the design of measures of outcomes that are used to evaluate those therapies.

Promoting Knowledge Accumulation About Intervention Effects: Exploring Strategies for Standardizing Statistical Approaches and Effect Size Reporting

Toward the goal of more rapid knowledge accumulation via better meta-analyses, this article explores statistical approaches intended to increase the precision and comparability of effect sizes from education research. As computation of the total variance can be complex in multilevel studies, a shiny application is provided to assist with computation of the total variance and subsequent effect size.
