Instructional leadership has become the dominant paradigm in principal preparation and professional learning. In parallel, teacher evaluation has risen in prominence. Using interviews from 84 principals in 23 districts and three states, we asked how teacher evaluation influenced principals' reported priorities and conceptions of instructional…

There is a defined need to provide accessible and effective professional development for 4-H educators. Lesson study is a Community of Practice-based approach to educator professional development. Prior research has shown lesson study to be effective with 4-H staff, adult volunteers, and teen volunteers. This inquiry, a multisite case study, was…

Under the Every Student Succeeds Act, whole-school reforms will continue to be a prominent strategy for improving student outcomes in low-performing schools. As reform models have proliferated, so has research evaluating the impact in reform schools. However, previous evaluations have rarely examined unintended spillover effects in nonreform…

Background: Many studies have shown that ambitious, "student centered" approaches to STEM instruction benefit K-12 student learning. However, relatively little research has systematically investigated the learning processes that support teachers to skillfully enact these challenging pedagogies. In this study, we used a mixed-methods,…

Background: Collaboration among teachers is now considered a marker of effective schools and key to creating successful professional learning opportunities. However, the nature and efficacy of collaboration vary widely, and research suggests that collaborative efforts often fail to promote teacher development. Purpose: This study draws on…

Rigorous college-and-career readiness standards require significant shifts in typical mathematics instruction. Many schools and districts employ coaches to support instructional changes. Although there is evidence that coaching programs can support teaching improvement, research has yet to identify high-leverage coaching practices. In…

Many prior studies have explored average differences in initial levels of teaching effectiveness among graduates from different teacher preparation programs (TPPs) and the features of preparation that predict these differences. We focus on another important dimension of effectiveness--how graduates from different TPPs improve over time. Examining…

Like other public workers, teachers typically receive high and compressed ratings that do little to differentiate them based on performance. Motivated by empirical evidence of substantial variation in effectiveness among teachers, there has been a recent push to develop more informative evaluation systems with greater ratings dispersion. We study…

Attempts to scale up instructional interventions confront implementation challenges that mitigate their ultimate impact on teaching and learning. In this article, we argue that learning about adaptation during the design and implementation phases of reform is critical to the development of interventions that can be implemented with integrity at…

Previous reports suggest that administrators rarely dismiss low-performing teachers despite the changing policy landscape allowing them to do so. This brief uses survey data from Tennessee to investigate the underlying reasons explaining administrators' decisions to retain low-performing teachers. The presented analysis suggests that…

Children with or at risk of disabilities engage in fewer and less complex social interactions (SIs) than their typically developing peers. The playground is an ideal setting for teachers to promote SIs among children. However, few studies have examined practical and meaningful strategies for supporting teachers in effectively facilitating SIs.…

Just a few years ago, tenure appeared low on the reform list for state policy makers and district administrators, viewed as too hot an issue politically to challenge. But it was front and center in the 2014 landmark "Vergara v. California" lawsuit, which challenged teacher tenure and related policies. Yet whether to grant tenure or not…

The answer to the question, Can evaluation improve teaching? is a qualified yes. Teacher evaluation has changed and the role of the principal has changed as well; the focus now is on evidence, not merely good judgment. With the right tools, systems, and support, it should be possible to help improve teaching performance and student learning…

In a private room at the back of a busy restaurant just outside of Tampa, Florida, drinks and appetizers went unnoticed as 12 diners sat around one large table and engaged in multiple rapid-fire conversations about professional learning. On one side of each conversation were representatives of Memphis (Tennessee) City Schools. The district was in…

This paper describes how a Tennessee school district is lessening the differences in achievement between inner-city schools and their suburban counterparts by bettering the teaching staffs in the inner-city schools. The story highlights two pillars of the almost-stunning progress achieved by what were once bottom-of-the-barrel schools. One, the…
