Background: Stigmatizing attitudes toward mental illness and low mental health literacy have been identified as links to social adversity, and barriers to seeking and adhering to treatment among adolescents suffering from mental illness. Prior research has found that it is possible to improve these outcomes using school-based mental health…

Background: This study investigated whether a personalized life story book and rummage box enhanced well-being and led to changes in behaviour for people with Down syndrome (DS) who have dementia. Materials and Methods: A randomized single case series design was used with five participants who had DS and a diagnosis of dementia. Participants were…

Demands for scientific knowledge of what works in educational policy and practice has driven interest in quantitative investigations of educational outcomes, and randomized controlled trials (RCTs) have proliferated under these conditions. In educational settings, even when individuals are randomized, both experimental and control students are…

When randomized experiments are infeasible, quasi-experimental designs can be exploited to evaluate causal treatment effects. The strongest quasi-experimental designs for causal inference are regression discontinuity designs, instrumental variable designs, matching and propensity score designs, and comparative interrupted time series designs. This…

In this response to David Stoesz' critique, "The Child Welfare Cartel," the authors agree that child welfare research and training must be improved. The authors disagree, however, with Stoesz' critique of social work education, his assessment of the most-needed forms of child welfare research, and his depiction of the goals and…

In response to "The Child Welfare Cartel," defenders of the National Child Welfare Workforce Institute (NCWWI) make three errors: First, restricting federal funds to schools of social work is "not" authorized by the statute cited in the creation of NCWWI. Second, social work is "not" the only discipline engaged in…

Many school systems are adopting new curricula in response to more rigorous standards that require higher-order thinking skills. This chapter presents implementation findings from a randomized, controlled trial of the Cognitive Tutor Geometry curriculum. We found a significant negative effect on student achievement despite the curriculum's focus…

This article reports on a study that investigated the effects of two feedback exposure conditions on the acquisition of two Turkish morphemes. The study followed a randomized experimental design with an immediate and a delayed posttest. Forty-two Chinese-speaking learners of Turkish were randomly assigned to one of three groups: receivers,…

The objective of this meta-analysis is to rigorously assess the participant effects of private school vouchers, or in other words, to estimate the average academic impacts that the offer (or use) of a voucher has on a student. This review adds to the literature by being the first to systematically review all Randomized Control Trials (RCTs) in an…

Despite recent emphasis on the use of randomized control trials (RCTs) for evaluating education interventions, in most areas of education research, observational methods remain the dominant approach for assessing program effects. Over the last three decades, the within-study comparison (WSC) design has emerged as a method for evaluating the…

Purpose: This study compared the effectiveness of two grammar treatment procedures for children with specific language impairment. Method: A double-blind superiority trial with cluster randomization was used to compare a cueing procedure, designed to elicit a correct production following an initial error, to a recasting procedure, which required…

The goal of this study is to better understand how methods for estimating treatment effects of latent groups operate. In particular, the authors identify where violations of assumptions can lead to biased estimates, and explore how covariates can be critical in the estimation process. For each set of approaches, the authors first review the…

Across the disciplines of economics, political science, public policy, and now, education, the randomized controlled trial (RCT) is the preferred methodology for establishing causal inference about program impacts. But randomized experiments are not always feasible because of ethical, political, and/or practical considerations, so non-experimental…

Little research has been conducted on unconditional cash transfers (UCTs) despite their growing prevalence in Africa, including South Africa, Zambia, Zimbabwe, Kenya, Malawi, Lesotho, and Uganda. In this study, researchers implemented a randomized control trial with over 2,500 households to investigate the impact of Africa's child grant program on…

Consultation is essential to the daily practice of school psychologists (National Association of School Psychologist, 2010). Successful consultation requires fidelity at both the consultant (implementation) and consultee (intervention) levels. We applied a multidimensional, multilevel conception of fidelity (Dunst, Trivette, & Raab, 2013) to a…
