IRIS Spotlight


The IRIS Center was invited to be included in a new initiative sponsored by the European Agency for Special Needs and Inclusive Education and UNESCO: Inclusive Education in Action: Empowering Teachers: Empowering Learners ( UNESCO is developing a knowledge-base about inclusive teaching and learning as the agency seeks to create a better worldwide understanding of inclusive education and to put an end to any child being denied an educational opportunity. Its stated purpose is “to provide on-line materials for the target groups of policy makers and other key stakeholders working to develop equity and equal opportunities for all within education systems—with a particular focus on teacher education policy and practice.” In this regard, descriptions and illustrations of IRIS resources can now be accessed at the initiative’s Website: The IRIS Center is one of only two U.S.- based centers featured in this collection.

New Research

  • The Efficacy of IRIS STAR Legacy Modules Under Different Instructional Conditions

    Among their findings on the effectiveness of IRIS Modules, Kristin L. Sayeski, Bethany Hamilton-Jones, and Susan Oh reported that “Strong effect sizes from pretest to posttest were found across all three [of the included] modules across all conditions.” Other significant findings support the use of IRIS Modules in flipped classroom conditions, particularly for content on procedural knowledge of the implementation of evidence-based practices, as well as the maintenance of that knowledge over time.

Test, Amy Kemp-Inman, Karen Diegelmann, Sara Beth Hitt, and Lauren Bethune conducted an analysis of the trustworthiness of Websites that claimed to provide information on evidence-based practices in special education.
