|NCSER 2020001||An Introduction to Adaptive Interventions and SMART Designs in Education
Educators must often adapt interventions over time because what works for one student may not work for another and what works now for one student may not work in the future for the same student. Adaptive interventions provide education practitioners with a prespecified, systematic, and replicable way of doing this through a sequence of decision rules for whether, how, and when to modify interventions. The sequential, multiple assignment, randomized trial (SMART) is one type of multistage, experimental design that can help education researchers build high-quality adaptive interventions.
Despite the critical role adaptive interventions can play in various domains of education, research about adaptive interventions and the use of SMART designs to develop effective adaptive interventions in education is in its infancy. To help the field move forward in this area, the National Center for Special Education Research (NCSER) and the National Center for Education Evaluation and Regional Assistance (NCEE) commissioned a paper by leading experts in adaptive interventions and SMART designs. This paper aims to provide information on building and evaluating high-quality adaptive interventions and review the components of SMART designs, discuss the key features of the SMART, and introduce common research questions for which SMARTs may be appropriate.

|NCEE 20184002||Asymdystopia: The threat of small biases in evaluations of education interventions that need to be powered to detect small impacts
Evaluators of education interventions are increasingly designing studies to detect impacts much smaller than the 0.20 standard deviations that Cohen (1988) characterized as "small." While the need to detect smaller impacts is based on compelling arguments that such impacts are substantively meaningful, the drive to detect smaller impacts may create a new challenge for researchers: the need to guard against smaller inaccuracies (or "biases"). The purpose of this report is twofold. First, the report examines the potential for small biases to increase the risk of making false inferences as studies are powered to detect smaller impacts, a phenomenon the report calls asymdystopia. The report examines this potential for both randomized controlled trials (RCTs) and studies using regression discontinuity designs (RDDs). Second, the report recommends strategies researchers can use to avoid or mitigate these biases. For RCTs, the report recommends that evaluators either substantially limit attrition rates or offer a strong justification for why attrition is unlikely to be related to study outcomes. For RDDs, new statistical methods can protect against bias from incorrect regression models, but these methods often require larger sample sizes in order to detect small effects.
|NCEE 20174026||Comparing Impact Findings from Design-Based and Model-Based Methods: An Empirical Investigation
This report compares empirical results from different approaches to analyzing data from randomized controlled trials (RCTs). It focuses on how impact estimates compare between recently-developed design-based methods and traditional model-based methods. Design-based methods use the potential outcomes framework and known features of study designs to connect statistical methods to the building blocks of causal inference. They differ from model-based methods that have commonly been used in education research, including hierarchical linear model (HLM) methods and robust cluster standard error (RCSE) methods for clustered designs. This study re-analyzes nine past RCTs in the education area using both design- and model-based methods. The study finds that model-based and design-based methods yield very similar impact estimates and levels of statistical significance, especially when the underlying analytic assumptions (e.g., weights used to aggregate clusters and blocks) are aligned.
|NCES 2017092||A Quarter Century of Changes in the Elementary and Secondary Teaching Force: From 1987 to 2012
This report looks at changes in several key characteristics of the teaching force between the 1987-88 and 2011-12 school years, including the number of teachers, the level of teaching experience, and the racial/ethnic diversity of the teaching force. The report focuses on how these demographic changes varied across different types of teachers and schools.
Among the findings about changes in the teacher workforce over this 25 year period:
This report utilizes data from the Schools and Staffing Survey (SASS), a large-scale sample survey of elementary and secondary teachers and schools in the United States. SASS has been conducted seven times—in school years 1987-88, 1990-91, 1993-94, 1999-2000, 2003-04, 2007-08, and 2011-12.

|NCER 20142000||Partially Nested Randomized Controlled Trials in Education Research: A Guide to Design and Analysis
In some tests of educational interventions, individual students are randomized directly to the treatment or control group, and both intervention and control protocols are administered in an individual setting. Such an experiment is an Individual-Level Randomized Controlled Trial (I-RCT). In other tests, clusters of students (e.g., classrooms) are randomized. This sort of experiment is called a Cluster Randomized Controlled Trial (C-RCT). However, in some designs, students in the treatment group are clustered like those in a C-RCT, but students in the control group are unclustered, like students in an I-RCT. This design is called a Partially Nested Randomized Controlled Trial (PN-RCT). It is partially nested because students in the treatment group are nested in some higher level unit, such as a tutoring group or class, but students in the control group are not nested as part of the experimental design.
This paper, commissioned by the National Center for Education Research, provides readers with an introduction to PN-RCTs and ways to design and analyze the results from them. This paper was written primarily for applied education researchers with introductory knowledge of quantitative impact evaluation methods. However, those with more advanced knowledge will also benefit from some of the technical examples and appendices.

* 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?
|NPEC 2012835||Defining and Reporting Subbaccalaureate Certificates in IPEDS
Subbaccalaureate certificates, postsecondary awards conferred as the result of successful completion of a formal program of study below the baccalaureate level, have become more prominent in higher education over the last decade. Institutions of all sectors offer subbaccalaureate certificates, which can range in length from a few months to more than 2 years. Subbaccalaureate certificates provide individuals with a means for gaining specific skills and knowledge that can be readily transferred to the workforce. As part of its mission to promote the quality, comparability, and utility of postsecondary data, the National Postsecondary Education Cooperative (NPEC) convened a working group to examine subbaccalaureate certificates and how they are reported in the U.S. Department of Education's Integrated Postsecondary Education Data System (IPEDS).
