Early education programs are increasingly being promoted by states and the federal government as an integral part of their efforts to ensure that all children enter school ready to learn. As these programs and their enrollments have grown in recent years, so too have efforts to monitor their quality and performance. A common focus is on…

The What Works Clearinghouse (WWC) Standards Briefs explain the rules the WWC uses to evaluate the quality of studies for practitioners, researchers, and policymakers. This brief explains what baseline equivalence is and why it matters. As part of the WWC review process for certain types of studies, reviewers assess whether the intervention group…

In education, there is ample evidence that some schools far outperform others at raising student achievement even when accounting for differences in the students they serve and the resources at their disposal. Differences in the human capital stock of teachers across schools cannot fully account for the differential productivity across schools. In…

This guide is addressed to policy officials, program providers, and researchers who are seeking to: (1) identify and implement social programs backed by valid evidence of effectiveness; or (2) sponsor or conduct an evaluation to determine whether a program is effective. The guide provides a brief overview of which studies can produce valid…

Purpose: This policy brief, the second AERI-NEPC eBrief in the series "Understanding validity issues around the world", focuses on validity as it applies to test-based models of evaluation employed for schools, instructional programs, and teachers around the world. It discusses validity issues that could arise when data from student…

Background: Chronotype refers to individuals' preference for morning or evening activities. Its two dimensions (morningness and eveningness) are related to a number of academic outcomes. Aims: The main goal of the study was to investigate the incremental validity of chronotype as a predictor of academic achievement after controlling for a number…

This paper reviews current proposals concerning the definition of dyslexia and contrasts it with reading comprehension impairment. We then discuss methods for early identification and review evidence that teacher assessments and ratings may be valid screening tools. Finally, we argue that interventions should be theoretically motivated and…

States and districts have launched unprecedented efforts in recent years to build new feedback and evaluation systems that support teacher growth and development. These systems depend on trustworthy information about teaching effectiveness--information that recognizes the complexity of teaching and is trusted by both teachers and administrators.…

There is a growing consensus that teacher evaluation in the United States is fundamentally broken. Few would argue that a system that tells 98 percent of teachers they are "satisfactory" benefits anyone--including teachers. The nation's collective failure to invest in high-quality professional feedback to teachers is inconsistent with…

Research has long been clear that teachers matter more to student learning than any other in-school factor. Improving the quality of teaching is critical to student success. Yet only recently have many states and districts begun to take seriously the importance of evaluating teacher performance and providing teachers with the feedback they need to…

No one has a bigger stake in teaching effectiveness than students. Nor are there any better experts on how teaching is experienced by its intended beneficiaries. Only recently have many policymakers and practitioners come to recognize that--when asked the right questions, in the right ways--students can be an important source of information on the…

Quality measures were originally developed for research aimed at describing the settings that children spend time in and identifying the characteristics of these environments that contribute to children's development. They were also developed to guide improvements in practice. Increasingly, however, measures of quality are being used for further…

The Parent Education Profile (PEP) is an instrument used by family literacy programs to rate parents' support for children's literacy development. This article uses Critical Discourse Analysis to examine how the PEP constructs the ideal parent, the text's underlying assumptions about parenting and education, and its ideological effects. The…

This study elaborates the "what works?" question by exploring the effects of variability in program implementation quality on achievement. Particularly, the effects on achievement of computerized assessment of reading were investigated, analyzing data on 51,000 students in Grades 1-12 who read over 3 million books. When minimum implementation…

Higher elementary student scores on standardized tests do not mean educational improvement. Scores can be affected by teaching "to" the test, coaching on test taking, and skewed norms. Test scores have been declining at the secondary level. Included is a discussion of secondary tests. (MD)
