Using the Delphi Technique, a total of 33 expert panelists representing
universities, K-12 educators, informal science education organizations, national and
federal organizations such as NSF, NASA, and the Department of Education, and parents
grappled with policy imperatives needed for effective science teaching. Through a series
of three iterative questionnaires, panelists had the opportunity to build consensus, pool
judgments, and forecast themes that could potentially influence policymakers in science
education for the "Three R's" of professional development—renewal, retention, and recruitment.
