A variety of measures have been developed to quantify intervention effects for single-case experimental design studies. Within the family of non-overlap indices, the Tau-U measure is one of the most popular indices. There are several Tau-U variants, each one calculated differently. The appropriateness of each Tau-U variant depends upon the data…

Hierarchical linear modeling (HLM) has been recommended as a meta-analytic technique for the quantitative synthesis of single-case experimental design (SCED) studies. The HLM approach is flexible and can model a variety of different SCED data complexities, such as intervention heterogeneity. A major advantage of using HLM is that participant…

This dissertation is a three-piece dissertation, including two empirical research (Chapter 1 and Chapter 2) and a methodological improvement of prior work (Chapter 3), to address issues of the effects of approaches to learning on academic achievement in childhood and power analysis for a three-level model in meta-analysis. Approaches to learning…

Background: Rigorous meta-analysis holds promise to answer the ultimate important question in education: which interventions work and for whom? Evidence-based reform in education has contributed to a proliferation of well-designed experiments in recent years, which calls for updated systematic reviews. However, this proliferation is a double-edged…

Network meta-analysis compares multiple treatments from studies that form a connected network of evidence. However, for complex networks, it is not easy to see if the network is connected. We use simple techniques from graph theory to test the connectedness of evidence networks in network meta-analysis. The method is to build the adjacency matrix…

Higher education research, while a specialist and late developing field, has reached a level of maturity such that researchers have recently been endeavouring to summarize and synthesize what has been learnt. This article identifies and analyses many of the systematic reviews and meta-analyses of areas or aspects of higher education research that…

This meta-analysis evaluated the effectiveness of data-driven learning (DDL) among low-proficiency L2 English learners, addressing the mixed results found in previous meta-analyses. The study incorporated 38 studies involving 2085 participants, yielding 37 effect sizes from control-experimental (C/E) studies and 42 from pre- and post-test (P/P)…

This report provides a comprehensive review of the research on the effect of K-12 school funding on student outcomes. In other words, does money matter in education? This is the third edition of this review, with the first two editions having been published in 2012 and 2016. In the previous edition of this report, the authors reviewed the evidence…

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…

This article presents a meta-analysis of the existing literature using Stata 18.0, focusing on the effects of ITSs on learning attitudes, knowledge acquisition, learner motivation, performance, problem-solving skills, test scores, and educational outcomes across different countries and educational levels (k = 30, g = 0.86). The findings suggest…

The purpose of this study is to analyse trends in articles on the use of instructional technologies in the education of individuals with special needs, specifically those with mental disabilities and autism. The research was conducted in accordance with the PRISMA statement, and the studies were analysed through content analysis. Between 2015 and…

Background: Recent research has demonstrated the potential of mobile-assisted learning to enhance learners' learning outcomes. In contrast, the learning processes in this regard are much less explored using eye tracking technology. Objective: This systematic review study aims to synthesise the relevant work to reflect the current state of eye…

This study used network meta-analysis to investigate the impact of the use of interactive learning environments (ILE) tools (augmented reality (AR), virtual reality (VR), mixed reality (MIX), and interactive digital games (GAME)) in science education on learning outcomes. A total of 53 primary studies were retrieved from the literature according…

The increasing integration of artificial intelligence (AI) in education has raised significant questions about its pedagogical value, especially in language learning. This meta-analysis examines the extent to which AI contributes to the development of English-speaking and listening skills. A systematic review of the literature was conducted by the…

The CoI framework, widely recognized as a leading theoretical model for constructivist-based technology-enhanced learning, has attracted increasing attention from researchers. The abrupt shutdown caused by the pandemic has increased this interest by shifting traditional teaching to online instruction globally, even until now. Scholars in TESL/TEFL…
