A meta-analysis was conducted to investigate phonology's role in d/Deaf and hard of hearing (d/Dhh) children's development of reading, and their ability to access spoken-language phonology. A systematic search of databases and journals identified 27 studies, 7 of which met the inclusion criteria. The included studies, experimental or…

In this article, we consider the relationships between schools and their local religious contexts and develop a new empirically-informed middle-level theory for analysing these relationships as a complex framework of negotiations. This framework is based on a meta-synthesis of qualitative data from forty-five case-studies of schools in Great…

Intelligence tests and adaptive behavior scales measure vital aspects of human functioning. Assessment of each is a required component in the diagnosis or identification of intellectual disability. The present study investigated the population correlation between intelligence and adaptive behavior using psychometric meta-analysis. The main…

The current study examined the effects of higher order thinking skills (HOTS) interventions with gifted students in Taiwan. A total of 25 studies published between 1997 and 2017 were included. Twenty-nine effect sizes were extracted for the 25 studies. The small number of existing studies indicates a lack of scholarly attention to HOTS in gifted…

Tutoring--defined here as one-on-one or small-group instructional programming by teachers, paraprofessionals, volunteers, or parents--is one of the most versatile and potentially transformative educational tools in use today. Within the past decade, dozens of preK-12 tutoring experiments have been conducted, varying widely in their approach,…

In response to the increasing emphasis on 'evidence-based teaching', this article examines the privileging of randomised controlled trials and their statistical synthesis (meta-analysis). It also pays particular attention to two third-level statistical syntheses: John Hattie's "Visible learning" project and the EEF's "Teaching and…

In studies with time-to-event data, outcomes may be reported as hazard ratios (HR) or binomial counts/proportions at a specific time point. If the intent is to synthesise evidence by performing a meta-analysis or network meta-analysis (NMA) using the HR as the measure of treatment effect, studies that only report binomial data cannot be included…

Text-to-speech and related read-aloud tools are being widely implemented in an attempt to assist students' reading comprehension skills. Read-aloud software, including text-to-speech, is used to translate written text into spoken text, enabling one to listen to written text while reading along. It is not clear how effective text-to-speech is at…

This study presents the results of a meta-analytic study about the effects of digital game-based learning (DGBL) on vocabulary. The results of the study showed that the effects of DGBL on vocabulary learning may vary with game design features (Q = 5.857, df = 1, p = 0.016), but not with learners' age (Q = 0.906, df = 1, p = 0.341) or linguistic…

Objectives: This review evaluates the evidence on the effects of cognitive-behavioral therapy (CBT) on drug use reduction for young people in treatment for nonopioid drug use. Method: We followed Campbell Collaboration guidelines to conduct a systematic review of randomized and nonrandomized trials. Meta-analytic methods were used to…

Meta-analytic evidence suggests that children have higher cortisol levels in childcare than at home. In the present study change of morning to mid-afternoon levels of cortisol was explored at home and in childcare in a Norwegian sample of toddlers. Further, analyses of associations between change of cortisol levels in childcare and child-,…

Experimental work has shown that spatial experiences influence spatiotemporal metaphor use. In these studies, participants are asked a question that yields different responses depending on the metaphor participants use. It has been claimed that English speakers are equally likely to respond with either variant in the absence of priming. Related…

A wide variety of effect size indices have been proposed for quantifying the magnitude of treatment effects in single-case designs. Commonly used measures include parametric indices such as the standardized mean difference, as well as non-overlap measures such as the percentage of non-overlapping data, improvement rate difference, and non-overlap…

Creativity is a vital topic of various educational discourses, yet the support it receives within the school system is insufficient. This chapter focuses on four particular ways of making creativity more democratized, salient, and accessible in school settings. We start by exploring the educational benefits of egalitarian theoretical approaches to…

The present study addresses the question of whether school leadership matters. It employs second-order meta-analysis to synthesize results from 12 first-order meta-analyses examining school leadership effects published 2003-2019. These meta-analyses collectively examined 512 primary studies published across four decades (1978-2019). Results showed…
