We explore the use of instrumental variables (IV) analysis with a multisite randomized trial to estimate the effect of a mediating variable on an outcome in cases where it can be assumed that the observed mediator is the only mechanism linking treatment assignment to outcomes, an assumption known in the IV literature as the exclusion restriction.…

Although a growing body of research points to the critical need to foster reading, writing, speaking, and critical thinking skills for students in order to ensure their success in college, careers, and life, these efforts have tended to focus more on developing literacy skills in the early years, often ignoring secondary students.

In order to systemically improve student achievement in elementary literacy, a large urban school district partnered with a local university to develop a model for high-quality professional development that hopefully would result in long-term changes in teachers' literacy instructional/practices. Schools were selected based on their Adequate…

Rigorous research provides information that will allow other schools and districts to select interventions that have a scientifically based track record of effectiveness. All Striving Reader grants include the mandate to evaluate literacy intervention(s) targeted to adolescents who are reading significantly below grade level. Although all studies…

This report presents case studies of the three exemplary projects within the Special Emphasis Project, a federally funded national study of how intensive reading programs might change the patterns of elementary school students who read one or more grades below grade level. An introductory section provides information on the history, organization,…
