In this article, a group of inservice providers and beginning researchers describe their experiences in learning to conduct evaluation research on a long-term school-university partnership program. We offer the practical lessons we learned in how to undertake such a study, and we share the immediate and powerful effects that the process of…

This study uses Monte Carlo simulations to demonstrate that regression-discontinuity designs arrive at biased estimates when attributes related to outcomes predict heaping in the running variable. After showing that our usual diagnostics are poorly suited to identifying this type of problem, we provide alternatives. We also demonstrate how the…

This paper illustrates how information collected through interviews can develop a richer understanding of the assignment mechanism, which can result in more plausible causal effect estimates from observational studies and provides a roadmap for sensitivity analysis. Focusing on the issue of assignment to algebra in 8th grade, the author shows how…
