Scaling up educational interventions in the STEM (Science, Technology, Engineering, and Mathematics) field is critical but under-researched. We review and draw implications from a series of studies investigating the long-range impact of an implementation of an early mathematics scale-up model based on learning trajectories. Lasting effectiveness…

At the intersection of biology and computer science is the growing field of bioinformatics--the analysis of complex datasets of biological relevance. Despite the increasing importance of bioinformatics and associated practical applications, these are not standard topics in elementary and middle school classrooms. We report on a pilot project and…

The purpose of this article is to highlight and discuss the strategies used to diffuse and manage a primary ELT innovation in Greece, strategies that proved essential for developing stakeholders' acceptance and ownership of the innovation, thereby facilitating its further development and sustainability.

This is the second of three reports from MDRC's evaluation of the Success for All (SFA) scale-up demonstration, funded under the U.S. Department of Education's Investing in Innovation (i3) competition. The report presents updated findings on SFA's implementation and impacts in the scale-up sites participating in the evaluation. The i3 evaluation…

"Success for All" (SFA) is one of the best known and thoroughly evaluated school reform models. Further evaluation of the initiative is especially important for two reasons. First, the program model has continued to evolve over time, with a greater emphasis placed on the use of engaging technology in the classroom and on the deployment…

While researchers continue to debate teacher qualifications, explore how to get more qualified teachers into urban schools serving low-income students, or try to determine whether teachers who are successful with middle-class students would also be successful with pupils in low-income urban schools, one practicable idea can easily be overlooked.…
