Background: Power analysis and sample size planning are key components in designing cluster randomized trials (CRTs), a common study design to test treatment effect by randomizing clusters or groups of individuals. Sample size determination in two-level CRTs requires knowledge of more than one design parameter, such as the effect size and the…

Brad Jones; Narelle Eather; Andrew Miller; Philip J. Morgan – Physical Education and Sport Pedagogy, 2024
Background: There is a growing body of evidence showing the benefits to coaches and players in adopting a game-based pedagogical approach. Whilst the evidence in support of a game-based pedagogy continues to rise it is acknowledged that the complex art form of coaching is a uniquely personal one, where the coach may draw on previous first-hand…

Identifying effective methods that can counteract seasonal trends in learning loss is essential to ensure continuous literacy growth of young learners. Computer-assisted instruction (CAI) is a solution for providing an effective summer literacy program that could help offset summer learning loss. In this study, four-year-old students from South…

Juan David Parra; D. Brent Edwards Jr. – Critical Studies in Education, 2024
This paper seeks to raise awareness among educational researchers and practitioners of some significant weaknesses and internal contradictions of randomised control trials (RCTs). Although critiques throughout the years from education scholars have pointed to the detrimental effects of this experimental approach on education practice and values,…

Andrew P. Jaciw – American Journal of Evaluation, 2025
By design, randomized experiments (XPs) rule out bias from confounded selection of participants into conditions. Quasi-experiments (QEs) are often considered second-best because they do not share this benefit. However, when results from XPs are used to generalize causal impacts, the benefit from unconfounded selection into conditions may be offset…

Brown, John F. – Educational Research and Evaluation, 2022
This paper discusses adapting Churches' approach to large-scale teacher/researcher conceptual replications of major "science of learning" findings, to increase teachers' engagement with empirical research on, and building research networks for, gathering data on the science of learning. The project here demonstrated the feasibility of…

Yang, Yoon Jung; Chung, Kyong-Mee – Journal of Autism and Developmental Disorders, 2023
This study developed and tested the effectiveness of an app-based cognitive behavioral therapy (CBT) program in alleviating anxiety among adolescents and adults with autism without co-occurring intellectual disability. Thirty participants from 15 to 35 years old were randomly assigned to either the intervention or waitlist control group, and self-…

Windsor, Catriona; Zhang, Tingwei; Wilson, Nathan J.; Blyth, Katrina; Ballentine, Natalie; Speyer, Renée – Journal of Applied Research in Intellectual Disabilities, 2023
Background: Evidence-based interventions are essential for school-aged children with intellectual disabilities to facilitate development and promote future independence. Methods: Using a PRISMA approach, systematic screening of five databases was undertaken. Original randomised controlled studies with psychosocial-behavioural interventions were…

Max; Dodge, Kenneth A.; Greenberg, Mark T.; Lochman, John E.; McMahon, Robert J.; Pinderhughes, Ellen E.; Wilcox, Holly C. – Prevention Science, 2023
Psychotic-like experiences (PLEs) are common throughout childhood, and the presence of these experiences is a significant risk factor for poor mental health later in development. Given the association of PLEs with a broad number of mental health diagnoses, these experiences serve as an important malleable target for early preventive interventions.…

Ben Smith; Stephen P. Morris; Harry Armitage – Research Papers in Education, 2023
It is not uncommon for randomised trials in education to have the performance of sample members in national examinations as their primary outcome. In many cases, examination results are available as summary measures only. Taking the example of GCSE examination results in England, this paper shows that using summary measures of an underlying score…

Background: Physical activity (PA) may benefit academic performance, but it is unclear what kind of classroom-based PA is optimal for learning. Aim: We studied the effects of physically active maths lessons on children's maths performance and maths-related effects, and whether gender and previous mathematical or motor skills modify these effects.…

Steven Glazerman; Larissa Campuzano; Nancy Murray – Evaluation Review, 2025
Randomized experiments involving education interventions are typically implemented as cluster randomized trials, with schools serving as clusters. To design such a study, it is critical to understand the degree to which learning outcomes vary between versus within clusters (schools), specifically the intraclass correlation coefficient. It is also…

Bulus, Metin; Dong, Nianbo – Journal of Experimental Education, 2021
Sample size determination in multilevel randomized trials (MRTs) and multilevel regression discontinuity designs (MRDDs) can be complicated due to multilevel structure, monetary restrictions, differing marginal costs per treatment and control units, and range restrictions in sample size at one or more levels. These issues have sparked a set of…

Adam Sales; Ethan Prhiar; Thanaporn March Patikorn – Society for Research on Educational Effectiveness, 2021
In a randomized controlled trial (RCT), some subjects assigned to the treatment condition may not fully comply. Often there is interest in the effect of the treatment within the "principal stratum" of subjects who would comply if assigned to treatment. However, it is unknown which control subjects would have complied if treated and which…

Background/Context: Online training has become an increasingly attractive alternative to traditional training (Laurillard 2016; Castaño-Muñoz et al. 2018). The online delivery of training allows overcoming geographical barriers and reaching higher numbers of participants in a flexible way and at reduced cost. Online training also offers higher…
