Background/Context: Billions of dollars are spent annually on professional development (PD) for educators, yet few randomized controlled trials (RCT) have demonstrated the ultimate impact PD has on student learning. Further, while policymakers and others speak to the role schools should play in developing students' civic awareness, RCTs of PD…

Background: Educational outcomes for language minority (LM) children are of great concern across the nation because these students have lower grades, are rated by their teachers as having lower skills, perform worse on standardized tests, and are more likely to drop out than are non-LM students. Given this context of underperformance, there is a…

Background/Context: Schools have differential effects on student learning and development, but research has not generated much explanatory evidence of the social-psychological pathway to better achievement outcomes. Explanatory evidence of how normative conditions enable students to thrive is particularly relevant in the urban context where…

Background: Within the last few years, the focus on educational accountability has shifted from holding students responsible for their own performance to holding those shown to impact student performance responsible--students' teachers. Encouraged and financially incentivized by federal programs, states are becoming ever more reliant on…

Background: Despite polling data that suggests that teachers are well respected by the general public, criticism of teacher preparation by various organizations and interest groups is common, often highlighting the perceived need for increasing their rigor and performance. A number of studies and reports have critiqued teacher preparation, and…

Background: In the last decade, the effects of teachers on student performance (typically manifested as state-wide standardized tests) have been re-examined using statistical models that are known as value-added models. These statistical models aim to compute the unique contribution of the teachers in promoting student achievement gains from grade…

Background/Context: Since the 1970s, researchers have attempted to link observational measures of instructional process to student achievement (and occasionally to other outcomes of schooling). This paper reviews extensively both historical and contemporary research to identify what is known about effective teaching. Purpose/Objective: Good, after…

Background: There has been rapid growth in value-added assessment of teachers to meet the widely supported policy goal of identifying the most effective and the most ineffective teachers in a school system. The former group is to be rewarded while the latter group is to be helped or fired for their poor performance. But, value-added approaches to…

Background/Context: The stakes are getting higher for teachers daily as more and more states adopt hiring, firing, and tenure-granting policies based on teacher evaluations. Even more concerning is the limited discussion about whether or not high-stakes teacher evaluation can meet the intended outcome of improved student achievement, and at what…

Background/Context: Under supplemental educational services ("supplemental services"), a parental choice provision of the No Child Left Behind Act (NCLB), schools that have not made adequate yearly progress in increasing student achievement are required to offer low-income families free, afterschool tutoring. Existing research shows low…

Background/Context: Little research has directly examined whether principal leadership can increase the degree to which teachers work together regularly in focused ways around content. Prior research has shown that reform efforts seeking to alter the process of teaching can be successful if teachers collaborate to build capacity and improve…

Background: The field of higher education abounds with qualitative research aimed at highlighting the needs, struggles, strengths, and motivations of academically struggling students. However, because of the small-scale nature of these studies, they rarely enter the public debate or impact institutional policy concerning access, remediation,…

Background: Low community college completion rates are an area of concern for policymakers and practitioners. Although many students require developmental education upon entry, research suggests that even students who are deemed "college-ready" by virtue of their placement test scores or completion of developmental coursework may not…

Background: In schools accredited as "IB World Schools" by the International Baccalaureate Organization (IBO), teachers use IB curriculum and pedagogy to teach a range of courses that are intended to prepare IB-enrolled students for college. Over the past 18 years, the number of U.S. schools that implement IB programs has increased…

Background/Context: PISA has come up with an ingenious solution to the problem of how to measure student achievement across national school systems with different curricula. Instead of measuring how well students learn what they are taught in each system, it measures a set of economically useful skills that no one teaches. Purpose: The aim is to…
