This commentary is a response to those of Hall (2016) and Winebrenner (2016), which in turn were responses to the article the authors wrote on modality preferences and learning styles (Lodge, Hansen, & Cottrell, 2016). There are several key points the authors wish to address in this reply. Most importantly, and aligned with the aims and focus…

Single-case researchers frequently adopt a form of response-guided experimentation where decisions about the design of the study are made based on an ongoing visual analysis. For example, multiple-baseline researchers may delay the start of intervention until data document a stable baseline pattern so that baseline trends can be reliably extended,…

The Scholarship of Teaching and Learning (SoTL) is a rich forum where scholars from different fields and philosophical orientations find space to share their research on teaching and learning in higher education. Within this article, we share our individual and collective experiences of why we perceive phenomenology as a methodology well suited…

This article provides an overview of the ethical tensions of preparing for ethnographic research with children in a rural district in Karnataka, India. Such children are at the receiving end of policy and international organisation interest, which alternately frames them as both victims of poverty and conflict and as agents of potential change in…

This article addresses the problem of estimating the proportion Pi[subscript S] of the population belonging to a sensitive group using optional randomized response technique in stratified sampling based on Mangat model that has proportional and Neyman allocation and larger gain in efficiency. Numerically, it is found that the suggested model is…

Seeing the present situation, I think that, at the very least, it behooves us as scientists and as human beings to work responsibly both for the future of our science and for the future of our languages, not so much for reward according to the fashion of the day, but for the sake of posterity. What we need to do now stares us in the face. If we do…

Researchers sometimes conduct a study and find that the predicted relation between variables did not exist or that the intervention did not have a positive impact on student outcomes; these are referred to as null findings because they fail to disconfirm the null hypothesis. Rather than consider such studies as failures and disregard the null…

This chapter examines the impact of declining student response rates on surveys administered at small- and medium-sized institutions. The potential for nonresponse bias and its effects are addressed.

Academic researchers in the infant and early childhood mental health field seek to understand the factors in early childhood that promote lifelong learning, health, and well-being. The inclusion of diverse and underrepresented populations, however, remains a challenge in rigorous research design. This article explores the challenges in addressing…

Although the Stanford Prison Experiment (SPE) has been challenged on methodological, theoretical, and ethical grounds, these criticisms have been largely ignored by teachers and textbook authors. Recent revelations arising from an analysis of the SPE archival materials, however, not only strongly support these past criticisms but also question the…

Despite abundant data and increasing data availability brought by technological advances, there has been very limited education policy studies that have capitalized on big data--characterized by large volume, wide variety, and high velocity. Drawing on the recent progress of using big data in public policy and computational social science…

Treatment effect estimates from a "regression discontinuity design" (RDD) have high internal validity. However, the arguments that support the design apply to a subpopulation that is narrower and usually different from the population of substantive interest in evaluation research. The disconnect between RDD population and the…

When researchers selectively report significant positive results, and omit non-significant or negative results, the published literature skews in a particular direction. This is called 'reporting bias,' and it can cause both casual readers and meta-analysts to develop an inaccurate understanding of the efficacy of an intervention. This paper…

The federal government funds a significant proportion of education research in the United States. But these research efforts have, by and large, fallen short of delivering on the promise to drive individual student outcomes across the country. By altering the priorities of education research to embrace a more complete research cycle, the federal…

The recent article by Nieuwoudt, Dickie, Coetsee, Engelbrecht and Terblanche (2019) entitled "Age- and education-related effects on cognitive functioning in Colored South African women" published in the journal Aging, Neuropsychology, and Cognition, attracted considerable negative attention, leading to its official withdrawal from…
