Researchers, theorists, and practitioners have expressed a renewed interest in the longitudinal dynamics of personality characteristics in adulthood, including organic life span trajectories and their amenability to volitional change. However, this research has apparently not yet expanded to include the Dark Triad (psychopathy, narcissism,…

Nonresponse bias is a widely prevalent problem for data on education. We develop a ten-step exemplar to guide nonresponse bias analysis (NRBA) in cross-sectional studies and apply these steps to the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011. A key step is the construction of indices of nonresponse bias based on proxy…

Longitudinal panel studies are widely used in developmental science to address important research questions on human development across the lifespan. These studies, however, are often challenging to implement. They can be costly, time-consuming, and vulnerable to test--retest effects or high attrition over time. Planned missingness designs (PMDs),…

Social science can be instrumental in illuminating responses to persistent social problems like racial or economic inequality. And a powerful starting point for studies that pursue this goal is a nuanced understanding of the problem at hand. That is, with a well-developed conceptualization of the contours, causes, and consequences of a given…

This strategic plan outlines the vision for IOE's research over the next five years, which can inspire and sustain the aspirations of researchers, share the vision with partners, and fulfil the responsibilities to the wider community. As well as the vision and mission, this plan also highlights IOE's research achievements, distinctive profile and…

In this retrospective commentary on "Acceptability of Behavioral Interventions Used in Classrooms: The Influence of Amount of Teacher Time, Severity of Behavior Problem, and Type of Intervention," I first examine the concept of social validity and related measurement challenges per Wolf's concerns about consumers' subjective reactions to…

This paper explores the process of going back in qualitative longitudinal research (QLR) to gather later accounts of unfolding personal experiences. The design of interview-based QLR is usually premised on collecting data, over-time, around an unfolding experience or event. This design facilitates the establishment of an on-going research…

The flipped classroom model of teaching can be an ideal venue for turning a traditional classroom into an engaging, inquiry-based learning (IBL) environment. In this paper, we discuss how two instructors at different universities made their classrooms come to life by moving the acquisition of basic course concepts outside the classroom and using…

The primary purpose of the 2017-2018 NC Pre-Kindergarten (NC Pre-K) Evaluation was to examine the effectiveness of the NC Pre-K Program using a randomized controlled trial (RCT) design. Because children are randomly assigned to either receive NC Pre-K (treatment) or not (control) in an RCT, differences in outcomes can be causally attributed to…

Multiple imputation (MI), a two-stage process whereby missing data are imputed multiple times and the resulting estimates of the parameter(s) of interest are combined across the completed datasets, is becoming increasingly popular for handling missing data. However, MI can result in biased inference if not carried out appropriately or if the…

This article describes issues in measuring school contexts with an eye toward understanding students' experiences and outcomes. I begin with an overview of the conceptual underpinnings related to measuring contexts, briefly describe the initiatives at the National Center for Education Statistics to measure school contexts, and identify possible…

Beginning with the 2015-2016 school year, the West Virginia Department of Education (WVDE) partnered with the National Institute for Early Education Research (NIEER) and Marshall University to conduct a five-year study of the quality of the West Virginia Universal Pre-K (WV Pre-K) program. The study was designed to examine the effectiveness of the…

The purpose of this article is to inform researchers about and encourage the use of longitudinal designs to further understanding of human resource development and organizational theory. This article presents information about a variety of longitudinal research designs, related statistical procedures, and an overview of general data collecting…

The purpose of this article is to describe the practice-based coaching model used in BEST in CLASS, a Tier-2 classroom-based intervention comprised of evidence-based instructional practices designed to prevent and ameliorate the chronic problem behaviors of young children at risk for the development of emotional/behavioral disorders. Following a…

Each year, the Interagency Autism Coordinating Committee (IACC) releases its annual list of scientific advances that represent significant progress in the field. The 20 studies selected have given new insight into the underlying biology of autism spectrum disorder (ASD) and potential risk factors, tested approaches for improving early screening…
