Mixed-effects models are an analytic technique for modeling repeated measurement or nested data. This paper explains the logic of mixed-effects modeling and describes two examples of mixed-effects analyses using R. The intended audience of the paper is psychologists who specialize in cognitive development research. Therefore, the concepts and…

This book is about scientific inquiry. Designed for early and mid-career researchers, it is a practical manual for conducting and communicating high-quality research in (mathematics) education. Based on the authors' extensive experience as researchers, as mentors, and as members of the editorial team for the Journal for Research in Mathematics…

Whether the goal is to identify and describe trends and variation in populations, create new measures of key phenomena, or describe samples in studies aimed at identifying causal effects, description plays a critical role in the scientific process in general and education research in particular. Descriptive analysis identifies patterns in data to…

Qualitative methods have become common in statistics education research, but questions linger about their role in scholarship. Currently, influential policy documents lend credence to the notion that qualitative methods are inherently inferior to quantitative ones. In this paper, several of the questions about qualitative research raised in recent…

This monograph looks first at opportunities provided by research in the adult literacy field and then identifies challenges to scientific research and suggests ways to address these challenges so that better evidence can be generated in the future. It has two goals that support the building of a stronger research base for the adult literacy…

This article describes the experiences of a former astronomer who is making the transition to astronomy education research as an international graduate student in the United States. The article describes the author's encounters with education research, its methodologies, and his changing research interests as he progresses through the graduate…

This discussion of the place of research in the field of library science notes empirical and scientific research; testing, analysis, and research design; theories and methodologies from other disciplines; the dilemma of quantification; library research needs; and the search for an audience. Twenty-six references are cited. (EJS)

The role of editors and peer reviewers in detecting and sanctioning scientific misconduct is analyzed, structural problems inherent in the process are examined, and best means of enabling peer and editorial roles in correction of misconduct are discussed. It is argued that the review process plays a limited corrective role. (MSE)

A survey of 334 biochemists identified 5 patterns of attitudes and beliefs about taking action for scientific misconduct: (1) reputational harm, (2) sanction criteria, (3) whistleblower stigmatization, (4) professional etiquette, and (5) ideological desensitization. Influences of intraprofessional status, departmental cohesion, institutional…

This article explores some of the intellectual bases of the apparent cultural divide between the fields of mathematics and mathematics education research. The chasm is in part attributable to epistemologies or theoretical "paradigms", fashionable in education, that dismiss or deny the integrity of fundamental aspects of mathematical and scientific…

There is a tendency to use case-study research methodology for research issues aiming at simply describing a complex situation, and to draw conclusions with insufficient rigour. Sound case-study research, however, follows discriminate rules which can be described in all the dimensions of a full case-study research process. This paper examines…

The hypothesis is the device scientists use to translate questions, theories, or proposed explanations into a form amenable to empirical research. This edition of W. W. Charter's treatise on clear, conceptual definitions and precise operational hypotheses, which was originally developed to assist students in educational policy and management…

This paper serves two purposes: (1) it outlines some of the conflicting characterizations of the differences among scientific and artistic approaches to qualitative research; and (2) it provides some illustrations from conceptual and empirical research to demonstrate that these are indeed differences that matter. The following four ways in which…

It is easy to observe that meta-analysis is quickly establishing itself as useful tool of the social sciences. Perusal of representative journals confirms that meta-analysis has been applied in various ways to diverse literatures. It is imperative, therefore, that reviewers, publishers, consumers, and critics of these reviews be best informed…

This article adopts "citation approach" to distinguish interdisciplinary or multidisciplinary research (IDR) from monodisciplinary research and begins to descrie how IDR differs from other research. Ten-year citation histories were constructed for sample of 1981 "citation classics" (over-cited articles) and examined for…
