Many statistical methods (estimators) are available for estimating the consensus value (or average effect) and heterogeneity variance in interlaboratory studies or meta-analyses. These estimators are all valid because they are developed from or supported by certain statistical principles. However, no estimator can be perfect and must have error or…

The taped problems (TP) intervention is a math fact fluency intervention designed to produce high rates of active and accurate academic responding. Multiple single-case design studies have examined the use of TP across grades of students, implementation group sizes, intervention settings, target math facts, total intervention time, application of…

Multisite research (MSR) offers the key advantages of greater statistical power and external validity via larger and more diverse participant pools. In second language acquisition (SLA) research, recent developments in meta-analysis have created a robust foundation for MSR. Although logistical and financial obstacles can complicate expansion…

This study explores the concept of authenticity in education, which has been, over the last 25 years, a powerful metaphor for educational practice, particularly as a guiding principle for some technological innovations that support student learning. The concept of authenticity has a variety of meanings, although a dominant interpretation is that…

Transformative learning (TL) goals are becoming commonplace in higher education, continuing education, and other adult learning contexts; however, valid and reliable assessments of TL are not so common. This imbalance begs the development of assessment methods that allow for a deeper understanding of how, when, and why deep reshaping of self takes…

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…

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…

The aim of this study is to investigate recent empirical research studies about 3D virtual learning environments. A total of 167 empirical studies that involve the use of 3D virtual worlds in education were examined by meta-review. Our findings show that the "Second Life" platform has been frequently used in studies. Among the reviewed…

The implementation of open educational resources (OER) at the course level in higher education poses numerous challenges to education practitioners--ranging from discoverability challenges to the lack of knowledge on how to best localize and utilize OER as courseware. Drawing on case studies of OER initiatives globally, the article discusses…

Purpose: This paper aims to explore why harmonisation, given its potential, is so difficult to achieve. It analyses the issues and challenges in achieving harmonisation of training and development across an industry. Design/methodology/approach: The approach was a meta-analysis of six research projects undertaken in the Australian rail industry.…

Purpose: This article illustrates how successful leaders combine the too often dichotomized practices of transformational and instructional leadership in different ways across different phases of their schools' development in order to progressively shape and "layer" the improvement culture in improving students' outcomes. Research…

As digital technologies permeate every aspect of our lives, the complexity of the educational settings, and of the technological support we use within them, unceasingly rises. This increased complexity, along with the need for educational practitioners to apply such technologies within multi-constraint authentic settings, has given rise to the…

Deficits in communication in people with disabilities are a major cause of challenging behaviors. Functional communication training (FCT) is one treatment developed to address both challenging behavior and instruction in replacement communicative behaviors by determining the function, or reason, the behavior occurs and developing a communication…

Within the emerging field of research on education for sustainability (EfS), case studies are an important if not the predominant research approach, although often criticised for its lack of internal and external validity and a tendency to draw conclusions with insufficient rigour. While, basic concerns have been expressed and discussed in an…

Studies that explore pedagogical content knowledge (PCK) in the field of mathematics education date back to the turn of the century in Turkey. In recent years, studies on PCK have gained momentum. Master's theses and doctoral dissertations have been written on PCK. In this context, there is a need to analyze the studies on PCK in Turkey to…
