RT Journal Article SR Electronic T1 The Educational Science and Scientifically Based Instruction We Need: Lessons from Reading Research and Policymaking JF Harvard Educational Review JO herp FD Harvard Educational Press SP 30 OP 61 DO 10.17763/haer.74.1.5445104446530382 VO 74 IS 1 A1 PRESSLEY, MICHAEL A1 DUKE, NELL A1 BOLING, ERICA YR 2004 UL http://harvardeducationalreview.org/content/74/1/30.abstract AB In this article, Michael Pressley, Nell Duke, and Erica Boling discuss the impact various scientific approaches have on early reading instruction research. The authors call for a second generation of scientifically based reading instruction that goes beyond the experimental, quasi-experimental, correlations, and qualitative designs currently informing public policy. The authors argue that the federal government's position on what constitutes "scientific research" embraces only a narrow range of potentially effective instruction. If this definition is expanded, educational policy, including for early reading instruction, can be much more successful.
