Background: Continued professional development (CPD) is required for updated skills and knowledge. This study evaluates the efficacy of a CPD programme for mainstream school teachers. Aims: In an 11-week intervention programme, speech-language therapists (SLTs) presented the participating teachers with whole-class teaching techniques aimed at…

A substantial number of randomized trials of educational interventions that have been conducted over the past two decades have produced null results, with either no impact or an unreliable estimate of impact on student achievement or other outcomes of interest. The investment of time and money spent implementing such trials warrants more useful…

Research in the UK suggests that multi-componential interventions focusing on language and pre-literacy skills can improve children's reading and language skills. However, simple translations of such programmes may not produce equivalent effects in diverse communities. The reasons for this are multi-faceted and include factors beyond the rationale…

Purpose: The purpose of this randomized controlled trial was to examine the effects of a multitiered system of language support (MTSLS) on kindergarteners' narrative retelling, personal stories, writing, and expository language. Method: Participants were 686 kindergarten students from four school districts in the United States. Twenty-eight…

The gold-standard for evaluating the effect of an educational intervention on student outcomes is running a randomized controlled trial (RCT). However, RCTs may often be small due to logistical considerations, and resulting treatment effect estimates may lack precision. Recent methods improve experimental precision by incorporating information…

Many public and private initiatives have focused on improving prekindergarten (PK) through Grade 12 mathematics education, given that the mathematics content learned before college is foundational for later learning and college success across STEM subjects. Although decades of educational research have studied PK-12 mathematics interventions, the…

Empirical evidence exists that enhancing students' language can promote the mathematics learning of multilingual students at risk, whereas other target groups (e.g., monolingual students, successful students, both with diverse academic language proficiency) have hardly been considered. This cluster-randomized controlled trial (N = 589)…

Understanding the factors that mediate the effect of educational or behavioral intervention is critical to advancing both research and practice. When properly implemented, mediators add depth to the results of intervention research, indicating why a program works, highlighting ways to enhance its effectiveness, and revealing the elements that are…

Student-teacher relationships are important to student outcomes and may be especially pivotal at the high school transition and for minoritized racial/ethnic groups. Although interventions exist to improve student-teacher relationships, none have been shown to be effective among high school students or in narrowing racial/ethnic disparities in…

In a randomized controlled trial of a teacher data-use intervention, the Linking Study tested the impacts of a cyclical and collaborative process that linked teachers' data on instructional practice with data on their students' learning. This article describes the theory of the intervention and its roots in the literature as a backdrop for an…

Pretense is a naturally occurring, apparently universal activity for typically developing children. Yet its function and effects remain unclear. One theorized possibility is that pretense activities, such as dramatic pretend play games, are a possible causal path to improve children's emotional development. Social and emotional skills,…

A habitually active environment is a feature of past times, and in stark contrast with that experienced by our children today. Consequently, twenty-first century physical education (PE) assumes a position of great responsibility. This is especially true in primary schools; a premise recently strongly supported by published evidence from the…

Community colleges are a large sector of postsecondary education. In 2016-2017, the United States had nearly 1,000 public 2-year postsecondary institutions (community colleges), serving almost nine million students, representing 39% of all undergraduates. The majority of entering community college students require developmental (or remedial) math.…

A growing body of research exists on the effectiveness of classroom-based intervention programs to prevent and ameliorate social, emotional, and learning difficulties demonstrated by young children at risk for emotional and behavioral disorders (EBD). Yet, little research has examined the influence of these targeted intervention programs on the…

We assessed the efficacy of an individual-based behavioral intervention on sexually transmitted infections' (STI) risk-reduction behaviors in Singapore. A randomized controlled trial of a behavioral intervention compared to usual care was conducted on sexually active heterosexual adolescents aged 16-19 years attending the only public STI clinic.…
