Research across multiple fields finds that adult-youth relationships are key influencers of development; however, professional learning about relational practice is limited. This suggests the need for targeted, efficient ways to help adults improve relational practice. We present a randomized controlled trial of Simple Interactions, a…

Objective: Our study aimed to compare the efficacy of artificial intelligence (AI)-based immersive training with human-led workshops to improve the English language skills of non-English early career researchers (NEECRs) in a Nigerian public university. Methods: Our study employed a randomized pretest/posttest control group design. A total of 124…

Community college students often lack an academic plan to guide their choices of coursework to achieve their educational goals, in part because counseling departments typically lack the capacity to advise students at scale. This randomized controlled trial tests the impact of guaranteed access to one of two alternative counseling sessions (group…

Background. Despite the emergence of new hepatitis C virus (HCV) antiviral medications, many people with chronic HCV know little about their disease, are at risk for transmitting HCV to others, and/or are not considered good treatment candidates. Self-management interventions can educate HCV-infected persons, improve their quality of life, and…

Many college students never take, or do not pass, required remedial mathematics courses theorized to increase college-level performance. Some colleges and states are therefore instituting policies allowing students to take college-level courses without first taking remedial courses. However, no experiments have compared the effectiveness of these…

Across the United States, more than half of entering freshmen discover they are ineligible for college-level coursework each year, most commonly in math. The readiness gap is widest when considering students at nonselective two-year colleges, and students who are black, Hispanic, or from low-income families. It often spells disaster for students…

Arachnids are predatory arthropods that are beneficial to humans in many ways, with common examples including spiders and scorpions. Despite the importance of arachnids to global ecosystems, the fear of spiders in specific human groups is well documented. Arachnids are a very diverse class (i.e., Arachnida) encompassing eleven extant orders with…

We conducted a randomized controlled potential efficacy trial to examine effects of two variants of the Tools for Teachers (TfT) professional development (PD) intervention on preschool teachers' implementation of embedded instruction practices and children's developmental and learning outcomes. Thirty-six preschool teachers recruited from three…

The aim of this study was to evaluate the impact of a social contact and education intervention to improve attitudes to mental illness in first-year social work students. This was a 3-month cluster randomized controlled trial with two parallel arms: intervention (87) and control group (79). The intervention was a workshop led by an OBERTAMENT…

Data-based problem solving is a hallmark of research-supported practices such as positive behavioral interventions and supports. In this study, we provided members of positive behavioral interventions and supports (PBIS) teams from 38 elementary schools with professional development focused on a research-supported problem-solving model…

Research Learning Communities (RLC) was an intervention that aimed to improve teaching quality and learning outcomes by raising teachers' awareness, understanding, and use of educational research in their teaching practice. Two Evidence Champion teachers from each school attended four RLC workshops with peers from up to four other schools.…

Background: We assessed the effectiveness of a simple intervention for increasing children's physical activity, play, perceived competence/social acceptance, and social skills. Methods: A cluster-randomized controlled trial was conducted, in which schools were the clusters. Twelve Sydney (Australia) primary schools were randomly allocated to…

We present main effects of treatment and moderating effects of student background on science and engineering outcomes for grades 3-5 children participating in an engineering intervention. Data is from a large-scale randomized-controlled trial of two matched pairs (intervention and comparison) of engineering units. The intervention curriculum…

Background: Methods need to be further developed to include non-randomised studies (NRS) in systematic reviews of the effects of health care interventions. NRS are often required to answer questions about harms and interventions for which evidence from randomised controlled trials (RCTs) is not available. Methods used to review randomised…
