The Simulated Instruction in Mathematics Professional Development (SIM PD) program is an innovative professional development (PD) program that offers (1) a focus on research-based math instructional strategies and (2) the unique opportunity to practice implementing these strategies in a mixed-reality environment with support of a coach and teacher colleagues. The program responds to the critical need in the field for ways to develop math teachers' ability to use the focal strategies, which h...

The proposed study will address a gap in the literature on whether attending an Early College High School (EC) results in significant gains in longer-term outcomes including college degree completion, workforce outcomes, college debt, and other life outcomes compared with not attending an EC. ECs are a type of dual enrollment program in which (1) it is expected that all students take college-level courses and (2) the prescribed curriculum facilitates the accrual of 2 years of college credits...

The Research and Development Center on Standards, Alignment, Instruction, and Learning (C-SAIL) will examine the implementation of college- and career-ready standards in 5 states, assess how they are related to student outcomes in 50 states, and test an intervention that supports standards-aligned instruction in 5 states. C-SAIL's launch occurs at a time when states and districts across the country are engaged in a variety of initiatives aimed at implementing college- and career-ready standa...
