Webinar 2: An Introduction to Meta-Analytic Techniques

Event Date: 
Mon, 09/28/2020 - 2:30pm to 4:00pm


This webinar is part of a 2-part series.

In recent years, science, technology, engineering, and mathematics (STEM) education researchers have used systematic review and meta-analysis methods to synthesize research evidence, identify gaps in the literature, develop instructional design guidelines, and inform teaching practice. Systematic literature reviews, however, are often confused with standard literature reviews. To reduce bias and increase transparency, a systematic literature review includes a precise research question with well-defined inclusion and exclusion criteria, formal literature search methods, and detailed study screening and coding protocols. In contrast, a standard literature review usually lacks formal review protocols and presents the author’s subjective interpretation of research on a given topic. After a systematic review, researchers often use formal statistical techniques known as meta-analysis to rigorously identify overall conclusions and variations in effect.

Join experts from the University of Oregon and the University of Louisville for a two-part webinar series designed to help researchers become better consumers of systematic reviews and meta-analyses. The series will provide an introduction to systematic reviews, highlight standards for top-quality reviews, and provide resources for learning about more advanced meta-analytic methods. Practical resources and applied STEM education examples will be emphasized. 

Webinar 1: An Introduction to Systematic Literature Reviews (held September 3, 2020)
Dr. Emily Tanner-Smith from the University of Oregon and Dr. Jeff Valentine from the University of Louisville will introduce the logic underlying systematic reviews. They will then share common challenges and provide practical advice for identifying the kinds of research questions that are suitable for systematic review, developing and assessing literature search strategies, and evaluating the credibility of the studies included in a review. Tools and resources will be shared to help the DRK-12 community apply those approaches.

Webinar 2: An Introduction to Meta-Analytic Techniques (held September 28, 2020) 
In the second part of this series, Drs. Tanner-Smith and Valentine will discuss how researchers can use meta-analytic procedures to combine quantitative data from multiple studies, statistically synthesize findings, and interpret meta-analytic results. They will discuss model choice in meta-analysis, describe the basics of computing and meta-analyzing study effects, illustrate how dependencies in effect sizes can be addressed, and discuss how publication bias tests are used (and misused).

Objectives of the Webinars:

Following participation, audience members will:

  • Understand systematic review and meta-analysis terminology
  • Identify the importance and benefits of systematic reviews
  • Understand key considerations for the literature search, screening, and coding in systematic reviews
  • Understand key considerations when synthesizing evidence using meta-analysis
  • Consider ways systematic reviews and meta-analytic techniques could further new learning in STEM education
