We investigated methods of including covariates in two-level models for cluster randomized trials to increase power to detect the treatment effect. We compared multilevel models that included either an observed cluster mean or a latent cluster mean as a covariate, as well as the effect of including Level 1 deviation scores in the model. A Monte…

Objective: To examine the efficacy of different methods (ie, in-class policy reading; in-class policy reading and discussion; no reading or discussion) to deliver campus sexual misconduct policy information to students on 7 campuses. Participants: A total of 1,195 participants at 7 colleges and universities participated in the study from August to…

The current study examines classroom-level peer behavioral regulation skills and their implications for children's school readiness outcomes. Specifically, this study will answer the following research questions: (1) Is the average level of peers' behavioral regulation skills in a classroom in the fall associated with growth in children's school…

This dissertation contains chapters that explore higher education policy issues related to student outcomes. In the first chapter, I examine the results of a controlled randomized trial of a brief, inexpensive phone call outreach to a sample of Pell eligible students at the University of Missouri intended to increase FAFSA filing, on-time FAFSA…

WorkAdvance is a sectoral workforce development program designed to meet the needs of workers and employers alike. For unemployed and low-wage working adults, the program provides skills training in targeted sectors that have good-quality job openings with room for advancement within established career pathways. For employers in those sectors,…

Student evaluations of college teaching have been endorsed and criticized for as long as they have been used as part of important decision-making practices in higher education. With the growth of distance education, the need for alternative approaches for these assessments has increased. We were interested in the extent to which outcomes were…

The Drug Education in Victorian Schools program provided integrated education about licit and illicit drugs, employed a harm minimization approach that incorporated participatory, critical thinking and skill-based teaching methods, and engaged parental influence through home activities. A cluster-randomized, controlled trial of the program was…

Many students lose knowledge and skills over the long summer break, and research suggests that low-income students fall further behind over the summer than their higher-income peers. Voluntary summer learning programs may provide an opportunity to stem summer learning loss and give struggling students additional learning opportunities. The Wallace…

Prior research has determined that low-income students lose more ground over the summer than their higher-income peers. Prior research has also shown that some summer learning programs can stem this loss, but we do not know whether large, district-run, voluntary programs can improve students' outcomes. To fill this gap, The Wallace Foundation…

The best way to teach children how to read has been debated for more than a century. Accumulating research now shows that there is no one best way to teach reading. The effect of various types of instruction depends on the constellation of skills learners bring to the classroom. In this article, we discuss the idea of…

The adoption of the Common Core State Standards for Mathematics (CCSSM, 2010) in 46 states has raised the mathematical proficiency bar for U.S. students. The advent of these new standards is at a time when the body of empirical evidence on the negative consequences of early and persistent difficulties in mathematics is clear, compelling, and…

The current article presents additional analyses of a classwide mathematics intervention, from a previously reported randomized controlled trial, to offer new information about the treatment and to demonstrate the utility of different types of effect sizes. Multilevel modeling was used to examine treatment effects by race, sex, socioeconomic…

Most homework sets in statistics courses are constructed so that students concentrate or "mass" their practice on a certain topic in one problem set. Distributed practice homework sets include review problems in each set so that practice on a topic is distributed across problem sets. There is a body of research that points to the…

The purpose of this addendum is to include within our discussion the findings of Girolametto et al. (2007), a randomized controlled trial of Teacher Talk training, an adapted version of Learning Language and Loving It (LLLI) (Weitzman and Greenberg, 2002). Teacher Talk does not include the coaching and video feedback elements of LLLI. Girolametto…
