Many teacher education researchers have expressed concerns with the lack of rigorous impact evaluations of teacher preparation practices. I summarize these various concerns as they relate to issues of internal validity, external validity, and measurement. I then assess the prevalence of these issues by reviewing 166 impact evaluations of teacher…

Presenting major advances in understanding learning disabilities (LDs) and describing effective educational practices, this authoritative volume has been significantly revised and expanded with more than 70% new material. Foremost LD experts identify effective principles of assessment and instruction within the framework of multi-tiered systems of…

Education systems are increasingly creating rich, longitudinal data sets with frequent, and even real-time, data updates of many student measures, including daily attendance, homework submissions, and exam scores. These data sets provide an opportunity for district and school staff members to move beyond an indicators-based approach and instead…

The vital role of principalship in improving schools in general and enhancing student achievement in particular has been well documented. Given its importance, there is a need for tools to improve principalship, particularly ones emphasizing those dimensions associated with student achievement. Given the accountability movement, with its…

This report summarizes the complex research literature on quantitative methods for assessing how impacts of educational interventions on instructional practices and student learning differ across students, educators, and schools. It also provides technical guidance about the use and interpretation of these methods. The research topics addressed…

Research has consistently shown that principal leadership matters for successful schools. Evaluating principals on the behaviors shown to improve student learning should be an important leverage point for raising leadership quality. Yet principals are often evaluated with the use of instruments with no theoretical background and little, if any,…

Instruments for evaluating the implementation of inquiry science in K-12 classrooms are necessary if evaluators and researchers are to know the extent to which programs are implemented as intended and the extent to which inquiry science teaching accounts for student learning. For evaluators and researchers to be confident about the quality of…

With many children and adults affected by Attention Deficit Hyperactivity Disorder, researchers strive to understand the underpinnings of ADHD and associated factors on both a basic and applied level. The goal of this volume is to explore some of the broad array of research in the field of ADHD. The 12 chapters cover a variety of topics as varied…

What really works in alternate assessment based on alternate achievement standards? Every state is working to know the answer--both to comply with federal requirements for evaluating students with severe cognitive disabilities, and to ensure that all students reach their full potential. This comprehensive book is the first to gather today's best…

This study examined the measurement of depressive symptoms among American Indian adolescents as assessed by the Center for Epidemiologic Studies Depression Scale (CES-D), Youth Self Report (YSR), and the Tri-Ethnic Center's for Prevention Research Depression Scale (TEDS). This analysis demonstrated that the TEDS had good internal consistency,…

Background/Context: For over two decades, the boundaries between the social sciences and the humanities have become blurred, and numerous articles and books have been written about the infusion of the arts in qualitative research as a means to collect and analyze data and to represent findings. Yet these arts-based research processes, although…

Value-added models help to evaluate the knowledge that school districts, schools, and teachers add to student learning as students progress through school. In this article, the well-known Education Value-Added Assessment System (EVAAS) is examined. The author presents a practical investigation of the methodological issues associated with the…

One of the best methods of formative assessment in academic areas and a method that exemplifies the characteristics of good measures is Curriculum-Based Measurement (CBM; Deno, 1985). Developed at the University of Minnesota in the early 1970's, CBM has been researched in academic areas including mathematics computation, concepts, and…

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…

There is a growing effort to make "proof" central to all students' mathematical experiences across all grades. Success in this goal depends highly on teachers' knowledge of proof, but limited research has examined this knowledge. This paper contributes to this domain of research by investigating preservice elementary and secondary school…
