  • Jackson: Choosing a Methodology: Philosophical Underpinning
    JACKSON: CHOOSING A METHODOLOGY: PHILOSOPHICAL UNDERPINNING Choosing a Methodology: Philosophical Practitioner Research Underpinning In Higher Education Copyright © 2013 University of Cumbria Vol 7 (1) pages 49-62 Elizabeth Jackson University of Cumbria [email protected] Abstract As a university lecturer, I find that a frequent question raised by Masters students concerns the methodology chosen for research and the rationale required in dissertations. This paper unpicks some of the philosophical coherence that can inform choices to be made regarding methodology and a well-thought out rationale that can add to the rigour of a research project. It considers the conceptual framework for research including the ontological and epistemological perspectives that are pertinent in choosing a methodology and subsequently the methods to be used. The discussion is exemplified using a concrete example of a research project in order to contextualise theory within practice. Key words Ontology; epistemology; positionality; relationality; methodology; method. Introduction This paper arises from work with students writing Masters dissertations who frequently express confusion and doubt about how appropriate methodology is chosen for research. It will be argued here that consideration of philosophical underpinning can be crucial for both shaping research design and for explaining approaches taken in order to support credibility of research outcomes. It is beneficial, within the unique context of the research, for the researcher to carefully

  • The Epistemology of Evidence in Cognitive Neuroscience1
    To appear in In R. Skipper Jr., C. Allen, R. A. Ankeny, C. F. Craver, L. Darden, G. Mikkelson, and R. Richardson (eds.), Philosophy and the Life Sciences: A Reader. Cambridge, MA: MIT Press. The Epistemology of Evidence in Cognitive Neuroscience1 William Bechtel Department of Philosophy and Science Studies University of California, San Diego 1. The Epistemology of Evidence It is no secret that scientists argue. They argue about theories. But even more, they argue about the evidence for theories. Is the evidence itself trustworthy? This is a bit surprising from the perspective of traditional empiricist accounts of scientific methodology according to which the evidence for scientific theories stems from observation, especially observation with the naked eye. These accounts portray the testing of scientific theories as a matter of comparing the predictions of the theory with the data generated by these observations, which are taken to provide an objective link to reality. One lesson philosophers of science have learned in the last 40 years is that even observation with the naked eye is not as epistemically straightforward as was once assumed. What one is able to see depends upon one’s training: a novice looking through a microscope may fail to recognize the neuron and its processes (Hanson, 1958; Kuhn, 1962/1970).2 But a second lesson is only beginning to be appreciated: evidence in science is often not procured through simple observations with the naked eye, but observations mediated by complex instruments and sophisticated research techniques. What is most important, epistemically, about these techniques is that they often radically alter the phenomena under investigation.

  • The Philosophical Underpinnings of Educational Research
    The Philosophical Underpinnings of Educational Research Lindsay Mack Abstract This article traces the underlying theoretical framework of educational research. It outlines the definitions of epistemology, ontology and paradigm and the origins, main tenets, and key thinkers of the 3 paradigms; positivist, interpetivist and critical. By closely analyzing each paradigm, the literature review focuses on the ontological and epistemological assumptions of each paradigm. Finally the author analyzes not only the paradigm’s weakness but also the author’s own construct of reality and knowledge which align with the critical paradigm. Key terms: Paradigm, Ontology, Epistemology, Positivism, Interpretivism The English Language Teaching (ELT) field has moved from an ad hoc field with amateurish research to a much more serious enterprise of professionalism. More teachers are conducting research to not only inform their teaching in the classroom but also to bridge the gap between the external researcher dictating policy and the teacher negotiating that policy with the practical demands of their classroom. I was a layperson, not an educational researcher. Determined to emancipate myself from my layperson identity, I began to analyze the different philosophical underpinnings of each paradigm, reading about the great thinkers’ theories and the evolution of social science research. Through this process I began to examine how I view the world, thus realizing my own construction of knowledge and social reality, which is actually quite loose and chaotic. Most importantly, I realized that I identify most with the critical paradigm assumptions and that my future desired role as an educational researcher is to affect change and challenge dominant social and political discourses in ELT.

  • The Rhetoric of Positivism Versus Interpretivism: a Personal View1
    Weber/Editor’s Comments EDITOR’S COMMENTS The Rhetoric of Positivism Versus Interpretivism: A Personal View1 Many years ago I attended a conference on interpretive research in information systems. My goal was to learn more about interpretive research. In my Ph.D. education, I had studied primarily positivist research methods—for example, experiments, surveys, and field studies. I knew little, however, about interpretive methods. I hoped to improve my knowledge of interpretive methods with a view to using them in due course in my research work. A plenary session at the conference was devoted to a panel discussion on improving the acceptance of interpretive methods within the information systems discipline. During the session, a number of speakers criticized positivist research harshly. Many members in the audience also took up the cudgel to denigrate positivist research. If any other positivistic researchers were present at the session beside me, like me they were cowed. None of us dared to rise and speak in defence of positivism. Subsequently, I came to understand better the feelings of frustration and disaffection that many early interpretive researchers in the information systems discipline experienced when they attempted to publish their work. They felt that often their research was evaluated improperly and treated unfairly. They contended that colleagues who lacked knowledge of interpretive research methods controlled most of the journals. As a result, their work was evaluated using criteria attuned to positivism rather than interpretivism. My most-vivid memory of the panel session, however, was my surprise at the way positivism was being characterized by my colleagues in the session.

  • Reporting Guidelines for Simulation-Based Research in Social Sciences
    Reporting Guidelines for Simulation-based Research in Social Sciences Hazhir Rahmandad John D. Sterman Grado Department of Industrial and Sloan School of Management Systems Engineering Massachusetts Institute of Technology Virginia Tech [email protected] [email protected] Abstract Reproducibility of research is critical for the healthy growth and accumulation of reliable knowledge, and simulation-based research is no exception. However, studies show many simulation-based studies in the social sciences are not reproducible. Better standards for documenting simulation models and reporting results are needed to enhance the reproducibility of simulation-based research in the social sciences. We provide an initial set of Reporting Guidelines for Simulation-based Research (RGSR) in the social sciences, with a focus on common scenarios in system dynamics research. We discuss these guidelines separately for reporting models, reporting simulation experiments, and reporting optimization results. The guidelines are further divided into minimum and preferred requirements, distinguishing between factors that are indispensable for reproduction of research and those that enhance transparency. We also provide a few guidelines for improved visualization of research to reduce the costs of reproduction. Suggestions for enhancing the adoption of these guidelines are discussed at the end. Acknowledgments: We would like to thank Mohammad Jalali for providing excellent research assistance for this paper. We thank David Lane for his helpful suggestions. 1. Introduction and Motivation Reproducibility of research is central to the progress of science. Only when research results are independently reproducible can different research projects build on each other, verify the results reported by other researchers, and convince the public of the reliability of their results (Laine, Goodman et al.

These are develop- ment of the field, the notion of serious games, the importance of debriefing, the need for research, and the emergence of a discipline. I suggest that the serious gaming com- munity has much to offer the discipline of simulation/gaming and that debriefing is vital both for learning and for establishing simulation/gaming as a discipline.

    Encyclopedia of Leadership ______________________________________________________________________________ Edited by G. Goethals, G. Sorenson, J. MacGregor Copyright © 2004 SAGE Publications London, Thousand Oaks CA, New Delhi www.sagepublications.com A R T I C L E Qualitative Research Sonia Ospina Robert F. Wagner Graduate School of Public Service New York University QUALITATIVE RESEARCH Leadership scholars seeking to answer questions about culture and meaning have found experimental and quantitative methods to be insufficient on their own in explaining the phenomenon they wish to study. As a result, qualitative research has gained momentum as a mode of inquiry. This trend has roots in the development of the New Leadership School, (Conger, 1999; Hunt, 1999), on the recent emergence of an approach to leadership that views it as a relational phenomenon (Fletcher, 2002), and on the increased recognition of the strengths of qualitative inquiry generally. Shank (2002) defines qualitative research as “a form of systematic empirical inquiry into meaning” (p. 5). By systematic he means “planned, ordered and public”, following rules agreed upon by members of the qualitative research community. By empirical, he means that this type of inquiry is grounded in the world of experience. Inquiry into meaning says researchers try to understand how others make sense of their experience. Denzin and Lincoln (2000) claim that qualitative research involves an interpretive and naturalistic approach: “This means that qualitative researchers study things in their
