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…

The relevance of the analyzed issue is caused by the growing slippage of research funds of sustainable development in its practice. The purpose of the article is the theoretical basis of the biosphere reserve as a scientific research subject that is relevant to rules of the scientific activity. The leading approach to the study of this issue is…

Programmatic text analysis can be used to understand patterns and reveal trends in data that would otherwise be difficult or impossible to uncover with manual coding methods. This work uses programmatic text analysis, specifically term frequency counts, to study nearly 10,000 chemistry thesis and dissertation titles from 1911-2015. The thesis and…

The past half-century has witnessed a dramatic increase in the scale and complexity of scientific research. The growing scale of science has been accompanied by a shift toward collaborative research, referred to as "team science." Scientific research is increasingly conducted by small teams and larger groups rather than individual…

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…

How do responsive adult-child interactions influence early language development? How do a child's language skills develop in tandem with social-emotional development, executive function, and literacy? What are effective ways to help parents support their child's development? Uncover the answers to these questions in this fascinating book, which…

It is the purpose of this article to discuss the development and application of a logic model in the context of a large scientific research program within the Commonwealth Scientific and Industrial Research Organisation (CSIRO). CSIRO is Australia's national science agency and is a publicly funded part of Australia's innovation system. It conducts…

This text is the foundation from which a distinguished lecture was developed focusing on the necessity for research in healthcare carried out with attention to issues of integrity, the hallmark of all commendable research. A cautionary historical review of research misconduct and related topics is provided. Research within a cultural context and…

Researchers undertake a number of different research evaluation tasks, taking up a substantial part of their research time--estimated to about one work month per year for a professor. This paper addresses the various evaluator roles and tasks researchers take on, and the tensions they involve. How the research evaluator role may conflict with the…

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…

As bibliometric indicators are objective, reliable, and cost-effective measures of peer-reviewed research outputs, they are expected to play an increasingly important role in research assessment/management. Recently, a bibliometric approach was developed and integrated within the evaluation framework of research funded by the National Cancer…

The article reviews a new method to identify common core elements of evidence-based practice (EBP) for children with disruptive behavior problems and their parents. This will not only help in characterizing practice, but also will enhance the skills and attitudes of therapists and be useful in implementing EBP in community-based service settings.

The environment for scientific research in public organisations is undergoing radical change, particularly with commercialisation pressures and blurring of the distinction between public and private research. The commercialisation pressures are reflected in government policy frameworks and institutional contexts for scientific work which are…

By common consent there is a "gold standard" in reference to which the efficacy of medical interventions needs to be evaluated. It is suggested in this paper that in educational research achievement of this gold standard is rarely possible. It does not follow, however, that research that falls short of this standard is therefore valueless; there…
