The purpose of this study was to compare the results of a regression discontinuity design (RDD) with those of an experimental design of a tiered vocabulary intervention for children at risk for reading disability to determine RDD's feasibility as a research methodology for this type of study. Researchers reanalyzed an archival dataset of a…

Poor mathematics performance in schools is both a national and an international concern. Teachers ought to be equipped with relevant subject matter knowledge and pedagogical content knowledge as one way to address this problem. However, no mathematics knowledge and practice standards have as yet been defined for the preparation of Foundation Phase…

This issue brief focuses on one particular report, released in September 2009, that has been widely cited by charter school advocates because it appears to show remarkable results. In the report, "How New York City's Charter Schools Affect Achievement," Stanford University professor Caroline Hoxby and her colleagues Sonali Murarka and…

The purposes of this study were to determine the effectiveness of a vocabulary intervention for first-grade students at risk for reading and language difficulties and to compare the results of a regression discontinuity design to those of an experimental design. The specific research questions were: (1) Do first-graders who are at risk of reading…

This study compared a multiple exemplar approach involving the training of key words and sentence structures to a typical repeated readings procedure for their effects on students' generalized oral reading fluency. The two training approaches were also compared in terms of their relative learning rates (i.e., fluency gain per minute of instruction…

Despite impressive advances in the science of reading intervention, how to best help at-risk readers remains a point of contention. Because reading represents the synthesis of background factors and language and reading skills--all of which develop with age and experience--this meta-analysis investigated whether development (as approximated by…

The problem investigated in this research study relates to the referral rate for special education evaluations between students of teachers who were exposed to the professional development and resources associated with the federally funded Reading First program and students of teachers who were not exposed to the program. The purpose of this study…
