This manuscript provides an overview of hierarchical linear modeling (HLM), as part of a series of papers covering topics relevant to consumers of educational research. HLM is tremendously flexible, allowing researchers to specify relations across multiple "levels" of the educational system (e.g., students, classrooms, schools, etc.).…

In educational research, a randomized controlled trial is the best design to eliminate potential selection bias in a sample to support valid causal inferences, but it is not always possible in educational research because of financial, ethical, and logistical constrains. One alternative solution is use of the propensity score (PS) methods.…

Current thinking on academic identities is heavily influenced by developments in other disciplines, notably sociology. This accords with Haggis's (2007) challenge for educational researchers to engage with current theory and methods from across the social sciences. However, the traditional sister discipline to education, psychology, seems…

This paper uses an analytical framework developed from the work of philosopher Roy Bhaskar and sociologist Margaret Archer to explore the emergence of a body of research on teaching and learning in South African higher education. This research, generated in a field known as "Academic Development" in South Africa and as "Educational…

Historically, "teacher action research" and "teacher research" have been terms mostly used at the PK-12 level. Yet, embracing it fully and visibly in the teacher education realm is important because it raises awareness of the critical and transformative aspects of teaching and learning. It allows teacher research to be made visible and validated…

Methodological rigor in intervention research is important for documenting evidence-based practices and has been a recent focus in legislation, including the No Child Left Behind Act. The current study examined the methodological rigor of intervention research in four school psychology journals since the 1960s. Intervention research has increased…

Teachers appear as characters in a wide range of literary writing. To date, few scholars have systematically studied the teachers who appear in works of literature. Much of the existing work has focused on relatively small numbers of teachers and has been presented in the form of brief essays rather than formal research (e.g., Booth, 2006; Crume,…

This article considers the value of clarity--of theory, method and purposes--in educational research. It draws upon the work of early critical theorist, Theodor Adorno, and particularly his notion of negative dialectics and his challenge to the traditional dichotomy of theory and practice. Using the notions of virtuous mess and wicked clarity, I…

In its 10th anniversary issue, "The Chronicle Review" asked a number of scholars to identify the "Defining Idea of the Next Decade." One nominee: the movement to abandon the disciplines in order "to meet the scholarly and public challenges educators face" (Ecklund, 2010). In Elaine Ecklund's perspective, it is only through interdisciplinary…

The notion of validity in the social sciences is evolving and is influenced by philosophy of science, critiques of objectivity, and epistemological debates. Methodology for validation of the knowledge claims is diverse across different philosophies of science. In other words, definition and the way to establish of validity have evolved as…

Diagnostic and formative assessment practices have been widely endorsed in the educational research literature. This article reports the findings of a small-scale study which investigated the extent to which these practices have been embraced in classroom teaching. The interview data from six lecturers and six students at a polytechnic in…

This article reports on a review of empirical research published in selected higher education journals in 2008, which was focused on examining how often theories are developed through research. This review found relatively little evidence of theory development. Drawing on the notions of internal and external languages of description, it is argued…

While design research can be useful for designing effective technology integrations within complex social settings, it currently fails to provide concrete methodological guidelines for gathering and organizing information about the research context, or for determining how such analyses ought to guide the iterative design and innovation process. A…

This study examined interventions for addition and subtraction that were implemented through single-case design (SCD) research studies. We attempted to extend prior SCD meta-analyses by examining differences in effect sizes across several moderating variables and by including a novel index of effect, improvement rate difference (IRD). We also…

For this literature review, the authors asked, "What is the role of gender in research about elementary-level women teachers and preservice teachers in the past 15 years, and what have scholars learned about the gendered nature of women's experiences in elementary-level preservice and in-service teaching in that time?" To be eligible for…
