NCSER 2015002 The Role of Effect Size in Conducting, Interpreting, and Summarizing Single-Case Research
The field of education is increasingly committed to adopting evidence-based practices. Although randomized experimental designs provide strong evidence of the causal effects of interventions, they are not always feasible. For example, depending upon the research question, it may be difficult for researchers to find the number of children necessary for such research designs (e.g., to answer questions about impacts for children with low-incidence disabilities). A type of experimental design that is well suited for such low-incidence populations is the single-case design (SCD). These designs involve observations of a single case (e.g., a child or a classroom) over time in the absence and presence of an experimenter-controlled treatment manipulation to determine whether the outcome is systematically related to the treatment.

Research using SCD is often omitted from reviews of whether evidence-based practices work because there has not been a common metric to gauge effects as there is in group design research. To address this issue, the National Center for Education Research (NCER) and National Center for Special Education Research (NCSER) commissioned a paper by leading experts in methodology and SCD. Authors William Shadish, Larry Hedges, Robert Horner, and Samuel Odom contend that the best way to ensure that SCD research is accessible and informs policy decisions is to use good standardized effect size measures—indices that put results on a scale with the same meaning across studies—for statistical analyses. Included in this paper are the authors' recommendations for how SCD researchers can calculate and report on standardized between-case effect sizes, the way in these effect sizes can be used for various audiences (including policymakers) to interpret findings, and how they can be used across studies to summarize the evidence base for education practices.

NCER 20162000 A Compendium of Math and Science Research Funded by NCER and NCSER: 2002–2013
Between 2002 and 2013, the Institute of Education Sciences (Institute) funded over 300 projects focused on math and science through the National Center for Education Research (NCER) and the National Center for Special Education Research (NCSER). Together, researchers funded by NCER and NCSER have developed or tested more than 215 instructional interventions (e.g., packaged curricula, intervention frameworks, and instructional approaches), 75 professional development programs, 165 educational technologies, and 65 assessments in math and science. NCER commissioned the development of this compendium with the intent to present information in a structured, accessible, and usable manner. This compendium organizes information on the NCER and NCSER projects into two main sections: Mathematics and Science. Within each section, projects are sorted into chapters based on content area, grade level, and intended outcome. The compendium also includes multiple appendices and an index to help readers locate specific types of information (e.g., projects that focus on English language learners, specific interventions).

NCSER 20133001 Synthesis of IES Research on Early Intervention and Early Childhood Education
The report describes what has been learned from research grants on early intervention and early childhood education funded by the Institute's National Center for Education Research and National Center for Special Education Research, and published in peer-reviewed outlets through June 2010. This synthesis describes contributions to the knowledge base produced by IES-funded research across four focal areas:
* Early childhood classroom environments and general instructional practices;
* Educational practices designed to impact children's academic and social outcomes;
* Measuring young children's skills and learning; and
* Professional development for early educators.
Research supported by IES has made significant contributions to the evidence base in these areas. The authors also raise important questions for education research in the future, including:
* What are the crucial features of high-quality early childhood education?
* Which instruction is most effective for which children and under what circumstances?
* How do we effectively and efficiently support teachers in improving their instruction?

NCSER 20133000 Translating the Statistical Representation of the Effects of Education Interventions Into More Readily Interpretable Forms
This new Institute of Education Sciences (IES) report assists with the translation of effect size statistics into more readily interpretable forms for practitioners, policymakers, and researchers. This paper is directed to researchers who conduct and report education intervention studies. Its purpose is to stimulate and guide researchers to go a step beyond reporting the statistics that represent group differences. With what is often very minimal additional effort, those statistical representations can be translated into forms that allow their magnitude and practical significance to be more readily understood by those who are interested in the intervention that was evaluated.

NCSER 20103006 Statistical Power Analysis in Education Research
This paper provides a guide to calculating statistical power for the complex multilevel designs that are used in most field studies in education research. For multilevel evaluation studies in the field of education, it is important to account for the impact of clustering on the standard errors of estimates of treatment effects. Using ideas from survey research, the paper explains how sample design induces random variation in the quantities observed in a randomized experiment, and how this random variation relates to statistical power. The manner in which statistical power depends upon the values of intraclass correlations, sample sizes at the various levels, the standardized average treatment effect (effect size), the multiple correlation between covariates and the outcome at different levels, and the heterogeneity of treatment effects across sampling units is illustrated. Both hierarchical and randomized block designs are considered. The paper demonstrates that statistical power in complex designs involving clustered sampling can be computed simply from standard power tables using the idea of operational effect sizes: effect sizes multiplied by a design effect that depends on features of the complex experimental design. These concepts are applied to provide methods for computing power for each of the research designs most frequently used in education research.
