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.…

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…

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…

Implementation intentions are self-regulatory strategies that increase the probability that desired goals will be achieved. While their effectiveness in the short term is well established in the literature, the long-term effects are not. The present study, which was conducted in France during the COVID-19 lockdown, aimed to test whether reminders…

Retention of early career teachers is a critical issue in education, with burnout and self-efficacy serving as important precursors to teachers leaving the field. An integration of the PAX Good Behavior Game (GBG; Barrish et al., 1969) and MyTeachingPartner (MTP; Allen et al., 2015) was tested in a randomized controlled trial (RCT) to investigate…

Social-emotional competence is critical to children's social and school success, prompting interest in understanding factors that promote these skills prior to elementary-school. Cognitive stimulation (e.g., reading, playing) is related to preschool children's social outcomes; However, few studies have examined these associations earlier, or…

Objective: To determine if treatment of co-occurring adult ADHD and Cannabis Use Disorder (CUD) with extended-release mixed amphetamine salts (MAS-ER) would be effective at improving ADHD symptoms and promoting abstinence. Method: A 12-week randomized, double-blind, two-arm pilot feasibility trial of adults with comorbid ADHD and CUD (n = 28)…

Educational researchers advocate the use of an effect size and its confidence interval to assess the effectiveness of interventions instead of relying on a p-value, which has been blamed for lack of reproducibility of research findings and the misuse of statistics. The aim of this study is to provide a framework, which can provide direct evidence…

Within a parallel-group randomized control trial, pain training's impact on Respite Workers' (RW) care approaches and training evaluations was explored. RW (n = 158) from 14 organizations received pain or control training following randomization. Researchers were blind until randomization; allocations were not shared explicitly with…

Online citizen science allows us to bridge the gap between researchers and nonresearchers and to improve the scientific literacy of nonresearchers. The aims of the present study were: (1) to determine whether a 5-week randomized control trial conducted by teachers in their classroom could improve 7- to 12-year-old children's inhibitory control…

Background: Children's language abilities set the stage for their education, psychosocial development and life chances across the life course. Aims: To compare the efficacy of two preschool language interventions delivered with low dosages in early years settings (EYS): Building Early Sentences Therapy (BEST) and an Adapted Derbyshire Language…

Many randomized controlled trials have investigated the role of school-based prevention interventions to reduce symptoms of anxiety and depression in young people. Systematic reviews have subsequently demonstrated a small, beneficial effect of these interventions when compared to a combined control group including usual care, no intervention, or…

Neuroanatomy is a crucial component of the physiotherapy curriculum, but its complexity can lead to "neurophobia" among students. Immersive virtual reality (IVR) offers an innovative alternative to traditional methods by providing interactive and realistic three-dimensional images of neurological structures. We aim to evaluate the…

Robotic therapies are receiving growing interest in the autism field, especially for the improvement of social skills of children, enhancing traditional human interventions. In this work, we conduct a scoping review of the literature in robotics for autism, providing the largest review on this field from the last five years. Our work underlines…
