Digital learning platforms (DLPs) are beginning to become open to research. Specifically, in our work in SEERNet, developers are extending five platforms, each used in either K-12 or higher education by more than 100,000 users, to enable third-party researchers to explore, develop, and test improvements. SEERNet seeks to enable equity-relevant…

The Programme for International Student Assessment (PISA) assesses the knowledge and skills in mathematics, reading and science of 15-year-old pupils in countries around the world. PISA is run by the Organisation for Economic Co-operation and Development (OECD), and assessment is typically undertaken every 3 years, allowing us to chart how…

ABRACADABRA (ABRA) is an evidence-based suite of interactive multimedia that engages learners in the development of core reading skills. This meta-analysis presents an update of the research evidence about the effectiveness of ABRA for elementary students. It reports 91 effect sizes in six reading-related outcomes for a sample of 7,388 students.…

Seven empirical studies from this special issue and an overview chapter are reviewed to illustrate several points about studying the possible effects of treatment intensity manipulations on generalized skill or knowledge acquisition in students with disabilities. First, we make a case in favor of studying intensity as separate from complexity and…

This paper is based on a series of previous research studies looking at the impact and development of teachers in the UK and internationally. It suggests that there is no convincing evidence, in terms of test outcomes, that some teachers are more or less effective with equivalent pupils. This is not necessarily because teachers are not…

The Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011), is collecting information about the early educational experiences of a nationally representative sample of children who were in kindergarten or who were of kindergarten age in ungraded classrooms or schools in the 2010-11 school year. The data collection began in…

For more than four decades the National Assessment of Educational Progress (NAEP) has tracked the achievement of U.S. students in major academic subjects. This national resource is the only assessment that states and now many urban districts can look to as an objective yardstick of their performance over time, relative to national benchmarks, and…

This is the first of two reports that summarize the findings from an impact evaluation of a violence prevention intervention for middle schools. This report discusses findings after 1 year of implementation. A forthcoming report will discuss the findings after 2 years and 3 years of implementation. In 2004, the U.S. Department of Education (ED)…

Although recent evidence suggests that non-cognitive skills such as engagement matter for academic and economic success, there is little evidence on how key educational inputs affect the development of these skills. We present a re-analysis of follow-up data from the Project STAR class-size experiment and find evidence that early-grade class-size…

Increased focus on assessment of student learning in the accreditation of higher education institutions offers new, challenging opportunities for institutional researchers. This article explores how institutional researchers can maximize these opportunities by offering methodological guidance in the assessment process and by designing new studies…

To alter the predominance of secondary school enrollment in lower vocational education in the Rotterdam district, the Educational Social Environment Project has developed and introduced kindergarten and elementary school curriculum for socially deprived children. This article describes the project's summative evaluation design, variable…

Major factors beyond a teacher's control that can influence teacher effectiveness are identified as sources of invalidity related to the inference of teacher effectiveness from students' achievement gains. These factors include: (1) student characteristics; (2) school characteristics; (3) test validity; and (4) pretest-posttest design…

This manual familiarizes data users with the procedures followed for data collection and processing of the second follow-up student component of the National Education Longitudinal Study of 1988 (NELS:88), with the corollary objective of providing necessary documentation for use of the data file. Chapter 1 presents an overview and history of the…

This manual familiarizes data users with the procedures followed for data collection and processing of the second follow-up dropout component of the National Education Longitudinal Study of 1988 (NELS:88), a survey of the educational and personal characteristics of students. The dropout data file contains records for 2,028 sample members who…

A feasibility plan is presented for a California comprehensive student information study that would identify factors affecting students' progress through California's entire educational system. The feasibility plan identifies: (1) potential improvements, (2) the study design required to achieve them, (3) the cost of implementing the design,…
