Scientific Method is a term denoting the principles that guide scientific research and experimentation, and also the philosophic bases of those principles. Whereas philosophy in general is concerned with the why as well as the how of things, science occupies itself with the latter question only, but in a scrupulously rigorous manner. Dereje Tadesse Birbirso (PhD) Scientific research Scientific research a systematic, controlled, empirical, and critical, investigation of hypothetical propositions about the presumed relations among the observed phenomena/variables. Dereje Tadesse Birbirso (PhD) 1.2. What is the purpose of research? • • • • • • • • To solve a social problem Improve the lives of individuals, citizens To make an organization, company more profitable To earn a degree To enhance one’s own academic status To advance human knowledge To improve national policies To genuinely understand what ‘X’ is or why and how ‘X’ occurs. Dereje Tadesse Birbirso (PhD) What is a research problem (or a topic for research)? A problem might be (material/physical and/or conceptual): • Absence, lacks • Mistakes, errors • Constraints • (More generally) social ills Dereje Tadesse Birbirso (PhD) I. Research Paradigm Dereje Tadesse Birbirso (PhD) 1. The nature of paradigm Paradigm a set of basic beliefs or worldview that defines, for the holder: • The nature of the ‘world’ [e.g. the what/object studied] • The individual’s place in it, and • The range of possible relationships to it and its parts. Basic beliefs=> accepted simply on faith but well argued and no way to establish their truthfulness Knowledge=>empirically tested, debated, validated, true belief Dereje Tadesse Birbirso (PhD) Your responses to the three fundamental questions that follow reveal what paradigm, among many, that you follow: 1) The ontological question: What is the form and nature of reality and, therefore, what is there that can be known (researched) about it? Ex. If ‘real’ world is assumed (critical realist paradigm), then what can be known about it is “how things really are or work” Dereje Tadesse Birbirso (PhD) 2) The epistemological question: What is the relationship between me the knower (or wouldbe knower) and what can be known ? • The answer given to this is already constrained by the answer give to the ontological question Ex. If critical realist paradigm is assumed, then the epistemological posture of the researcher is that in conceptual relativism to the reality and available data, attempting to explain the mechanism by which the reality emerged and exists. Dereje Tadesse Birbirso (PhD) 3) The methodological question: How can I the researcher (would-be knower) go about finding out whatever I believe can be known? The answer given to this question is already constrained by the response given to the two questions above. So NOT any methodology. Ex. If your take is ontological realism and epistemological relativism (above), judgmental rationalism which involves qualitative design/approach—action, reflection, observation, dialogue, debate on meaning, action etc—is selected Dereje Tadesse Birbirso (PhD) We may add: 4) The causality question: What causes a new quality/phenomenon/reality? [e.g. A problem/phenomenon researched) Your response that you select is already constrained by the response you gave to ontological, epistemological and methodological questions above. Dereje Tadesse Birbirso (PhD) Ex. If your paradigmatic assumption is critical realism (above), what caused the actual (here and now) reality is: • Bottom-up/local and global/top-down interaction of pre-structures and • It is only an emergent property of some deeper generative (past and wider) mechanisms Dereje Tadesse Birbirso (PhD) Some other causality perspectives: • Epiphenomenalism (one-way or linear causality) • Interactionism (two-way causality • Occasionalism (mediated by God on occasions when God needs to mediate) • Complex causality (an event/phenomena in a context is caused by spatio-temporally wide-and-long social events/phenomena) • Determinism (externally determined by socio-historical structure, etc • Reductionism (Macro factors determine the micro events) • Voluntarism (intentional action) Dereje Tadesse Birbirso (PhD) Therefore: Your PARADIGM = YOU Dereje Tadesse Birbirso (PhD) Paradigm defines for you: Ontological assumption Epistemological assumption Your Problematization: What falls within and outside the limits of legitimate research? Does the problem really exist? Your Theoretical/conceptual framework (Hypothesis)? Methodological assumption Your Design/Methodology? Causality assumption Your Analysis Strategies ? Dereje Tadesse Birbirso (PhD) Paradigm analysis Four distinct (but may be related) research paradigms can be identified: 1. Positivism (Logical positivism) 2. Post-positivism (Modernism) 3. Constructivism (Post-modernism) 4. Critical realism (Critical theory) Let’s analyze each based on the three fundamental questions Dereje Tadesse Birbirso (PhD) (1) Positivism Definition: • Literally, positivism originated as a scholarly movement against the negative, ‘retrograde school’ of authors who wanted to shatter the Enlightenment—conservative apologists for the Dark Age/Middle Age, where science was dominated/contained by religion/dogma. • ‘Progress’ and ‘order’ are possible Dereje Tadesse Birbirso (PhD) 1. Ontology: Dualist; Naïve realism—objective reality, which is apprehendable in senseimpression 2. Epistemology: objective, empirical, value-free truth 3. Methodology: Experimental/manipulative; verification of hypotheses; chiefly quantitative 3. Causality: Linear causality Dereje Tadesse Birbirso (PhD) (2) Post-positivism/modernism 1. Ontology: Dualist; Objective reality, but only imperfectly and probabilistically apprehend able 2. Epistemology: Objectivist; findings probably true if reliable and valid 3. Methodology: Modified experimental; multiplism; falsification of hypotheses (=refutation); may include quantitative methods 4. Causality: Linear, reductionist/determinist, e.g. intentional Dereje Tadesse Birbirso (PhD) (3) Constructivism 1. Ontology: Ontological relativism—local and specific realities constructed and shaped by socio-historical, socio-political, socio-economic contexts and values crystallized as a result 2. Epistemology: Subjectivist—truth is contextbounded, value-laden and socially constructed 3. Methodology: Dialogic, hermeneutical, phenomenological 4. Causality: Complex causality; circular causality Dereje Tadesse Birbirso (PhD) (4) Critical realism 1. 2. 3. 4. Ontology: Ontological realism; Independent but open and stratified reality (a reality here-and-now is generated and manifestation of a deeper reality) Epistemology: Epistemological relativism; Knowledge is abstraction of reality and fallible but can explain or correspond to the mechanism/reality through critique, reflection (truth is possible) Methodology: Explanatory or causal analysis; Dialogic, participative inquiry; Critical practitioner inquiry; Critical or participatory action research Causality: Emergentism—top-down/outside-in and bottom-up/inside-out interaction ; entity relationism— iter- and intra-action; Dereje Tadesse Birbirso (PhD) 2. RESEARCH DESIGNS Research design The conceptual frame, a plan or a blueprint of how one intends conducting the research: • What data/reality is and how it is analysed: Qualitative? Quantitative? Mixed? • What the role of the researcher is: Objectivist? Subjectivist? Both? • What the purpose of research is vis-à-vis of the problem: Description? Interpretation? Prediction? Explanation? Transformation? Dereje Tadesse Birbirso (PhD) Qualitative v. Quantitative design • Subjective • Objective • Designed to deal with the complexities of meaning in social context, • Are naturalistic, • observational (not), • more focused on problems of validity than • Data will be “real, rich, deep” rather • Meaning as individualistic • Controlled • Experimental Dereje Tadesse Birbirso (PhD) • on those of reliability and generalizability. • Data is “hard and replicable” • Phenomenologism and verstehen: concerned with understanding human behavior from the actor's own frame of reference • Close to the data; the “insider” perspective Dereje Tadesse Birbirso (PhD) • Logical-positivism: “seeks the facts or causes of social phenomena with little regard for the subjective states of individuals” • Removed from the data; the “outsider” perspective • Grounded, discoveryoriented, exploratory • Expansionist, descriptive, and inductive • Process-oriented • Ungeneralizable; single case studies Dereje Tadesse Birbirso (PhD) • Ungrounded, verification-oriented, confirmatory, reductionist • Inferential, and hypothetico-deductive • Outcome-oriented • Generalizable; multiple case studies • Holistic • Assumes a dynamic reality • Data=> linguistic (written or spoken account or described event ) segment/text Dereje Tadesse Birbirso (PhD) • Particularistic • Assumes a stable reality • Data=>quantified figure Is Mixed (qualitative + Quantitative) design possible? • Support: Yes, e.g. triangulation for reliability • Objection: Paradigm incommensurability; It is just eclecticism for the sake of being eclectic; It is like adding two wrongs to get one right Dereje Tadesse Birbirso (PhD) 3. RESEARCH METHODOLOGY Methodology: • Is closely related to the theory of knowledge or epistemology; • Explores the methods by which research arrives at its posited truths concerning the object of study/problem; • Critically explores alleged rationales for these methods. • Explores how findings are accepted; • The confirmation relation between evidence and conceptual framework/hypothesis. Dereje Tadesse Birbirso (PhD) Hypothesis v. conceptual framework; I. Hypothesis: • An educated—and testable—guess about the answer to your research question • An attempt by the researcher to explain the phenomenon of interest/to-be-studied Types: • Null hypothesis always predicts that there will be no differences between the groups being studied. • Alternate hypothesis predicts that there will be a difference between the groups Dereje Tadesse Birbirso (PhD) Drawbacks: • Seeks to make the situation conform to the hypothesis • Either/or (e.g. excludes and/or, neither) • Determinate/pre-fixed or closed-system • Monocausal • Top-down (Theory-driven) Dereje Tadesse Birbirso (PhD) II. Conceptual Framework: • Generic explanatory framework or researcher’s provisional answer to observed problem • Researcher’s guiding framework or heuristic device (basic belief or paradigmatic assumption; see above) • Includes such activities as providing models, offering exemplary studies of particular cases, developing established mechanisms (inter-/intraconnections) or categories Dereje Tadesse Birbirso (PhD) • Might seek to make the situation conform to the framework/hypothesis but violating the canons of controlled experiment by remaining open to the possibility that it will not Dereje Tadesse Birbirso (PhD) Sampling: Why sampling and a sample? How much of population is a sample? Sampling of : Subjects/objects Paradigm Design Methodology Methods Tools, etc Dereje Tadesse Birbirso (PhD) i. Random sampling Why randomness and random sampling? What techniques of random sampling ? Dereje Tadesse Birbirso (PhD) ii. Purposeful Sampling Why purposefulness and purposeful sampling ? When and how purposeful sampling ? Dereje Tadesse Birbirso (PhD) E.g. 1. My free act has a cause - namely, me. Why should we complain when the individual concept of 'me' intrinsically determines what I do? Is this not what is meant by freedom? That I am the source of my action, and not anyone or anything else? 2. For not only is evolution a process that makes philosophers and philosophy possible, but it provides a clear model for how processual novelty and innovation comes into operation in nature’s self-engendering and selfperpetuating scheme of things. Dereje Tadesse Birbirso (PhD) Purposeful sampling: • Choosing particular subjects to include because they are believed to facilitate the expansion of the developing theory” (Bogdan & Biklen, 1998: 65). • Seeking to be representative in a statistical sense, but to select units of study (individuals, groups or settings) that are theoretically meaningful and relate back to the original research question. • Patton (1990) the logic and power of purposeful sampling lies in selecting information-rich cases to study in depth. Dereje Tadesse Birbirso (PhD) Goals of qualitative research • Descriptive: Describing regularities– e.g., correlation • Experimentational: Hypothesis-testing by confirming or refuting hypothesis/conceptual framework • Interpretative: Understanding understandings (beliefs and behaviors/actions) of subjects/participants in their context Dereje Tadesse Birbirso (PhD) • Explanatory: Inquiring into delineating and explaining mechanisms by which causals-effectsconsequences sustains itself • Transformative: Inquiry into and changing or absenting of social evils (e.g. lack or diminishment of certain important skill/knowledge, ability) Dereje Tadesse Birbirso (PhD) Methodological fallacies to take care of in qualitative research: Research fits established theory/researcher hypothesis/respondent assumption or reality/mechanisms? Related to this question are: • Epistemological fallacy: Treating concepts as if they were the very things that they refer to, or confusing the nature of reality with our knowledge of reality. • Genealogical fallacy: Consists reducing (explaining away) a current state by referring to a former one. Dereje Tadesse Birbirso (PhD) • Naturalistic fallacy: the non-observance of the distinction between “facts” (the is) and “values” (the ought), or to attempts to reduce our similarly diverse and pervasive concept of goodness to a single, simple feature; • Epistemic fallacy: delimiting the ontology of the social to the limits of any epistemological activity of human agents OR the ‘idea that being [ontology] can always be analyzed in terms of our knowledge [epistemology] of being’. Dereje Tadesse Birbirso (PhD) • Anthropomorphic fallacies: We usually think of the world (event, phenomenon or a person) and we tend to think in terms of a person. Ex. taking the folk’s (lawpersons, informant) assumption as truth or fact of a situation/phenomenon Dereje Tadesse Birbirso (PhD) … methodological fallacies Research establishes social regularities or facts about individuals?: Related to this question are: I. Methodological individualism: Explaining higher-level structures can by reference to the properties of the lower-level entities that make them up. E.g. Using the characteristics and properties of individuals to explain a social phenomena. • This is unsatisfactory because (1) it suggests that social phenomena can be both decomposed into and explained by properties of individual phenomenon (2) usually individuals (e.g. respondents or informants) cannot explain, critically analyze, relate the here-andnow to the complex and deeper (social) realities. Dereje Tadesse Birbirso (PhD) II. Methodological holism/collectivism: Deducing higher level structure from properties of the simpler or simplest situation (s). E.g. Considering group attributes to explain individual’s This is unsatisfactory approach, because it 1) confers independent causal powers on collective entities, 2) elides more “micro” explanatory mechanisms that are located at the level of local, concrete, individual contexts, and 3) and neglects the complex processes of interaction between categories Dereje Tadesse Birbirso (PhD) III. Dialectic methodology/dialecticism: Dereje Tadesse Birbirso (PhD) 4. RESEARCH STRATEGY Research strategy or ‘strategy of inquiry’: • Comprises the skills, assumptions, and practices used by the researcher when moving from paradigm to research deign to collection of empirical data (Denzin & Lincoln 1994). • Frames research by putting constraints on acceptable theories and guiding the generation of valid and relevant data. • Involves optimization: specifying the kinds of possibilities that can be researched under the paradigmatic and pragmatic/contextual conditions. Dereje Tadesse Birbirso (PhD) Various strategies: I. Induction: Generating methods as well as concepts/model from context as well as interpretation/analysis of data II. Deduction: Using established hypothesis/theory/convention to collect and analyze data (hypothetico-deductive method) Dereje Tadesse Birbirso (PhD) III. Abduction: • To tentatively accept an explanatory hypothesis which, if true, would make the phenomenon under investigation intelligible • To interpret and recontextualize individual phenomena within a conceptual framework or a set of ideas. • To be able to understand something in a new way by observing and interpreting this something in a new conceptual framework Dereje Tadesse Birbirso (PhD) IV. Retroduction: • The movement from concrete phenomena to underlying structures and causal processes. But at the same time, we must move back to the concrete and look at how various different causal processes come together in a specific conjuncture. • From a description and analysis of concrete phenomena to reconstruct the basic conditions for these phenomena to be what they are. By way of thought operations and counterfactual thinking to argue towards transfactual conditions. • Investigation move from :ActionReason/MotivationDiscourse such as official policy, curricula, syllabi, rules, regulations, etc] and again repeating Re-analysis from: DiscourseReason/MotivationAction Dereje Tadesse Birbirso (PhD) V. Retrodiction: • Explanation by established mechanism—in which events are explained by postulating (and identifying) mechanisms which are capable of producing them. • Conceptually reorganizing well-established and easily comprehended material rather than simply uncovering what had been previously hidden (E.g. Kepler did it) Dereje Tadesse Birbirso (PhD) VI. Reflexivity/Reflective-/Dialogical strategy: Research reality is open, complex, dynamic and difficult to predict ahead: Being open to the research context and contingent to emergent methodological realities and events Taking analytic memo—methodological, theoretical, interpretational etc notes or memoing. Dereje Tadesse Birbirso (PhD) Involving participants/informants/respondents in shaping the research process, and generating, interpreting, triangulating and validating data Triangulating methodological frameworks, research methods, action-versus-words, an event versus events, a participant’s/respondent’s versus others’ words/action, etc. Dereje Tadesse Birbirso (PhD) Research qualities: Structuralist (bias, generalizability; repeatability; validity; correspondence; reliability); Hermeneutics-phenomenology; Post-Modernist (authenticity, trustworthiness, credibility/dependability, catalytic validity; reflectivity; dependability; Realist (attuning to the 3c--correspondence + coherence+ consensus); etc Dereje Tadesse Birbirso (PhD) i. Structuralism argumentations Structuralism: ‘an attempt to treat human activity scientifically by finding basic elements (concepts, actions, classes of works) and rules or laws by which they are combined’ (Dreyfus & Rabinow 1982) Structuralist quality premises: Avoiding bias--objectivity; generalizability; reliability/repeatability; validity/objectivity Structuralism drawbacks: Closed ontology—deletes any form of subjectivity (for objectivity), for there is ontologically nothing beyond the structure being studied. This leads to fallacies discussed earlier. Dereje Tadesse Birbirso (PhD) ii. Hermeneutics/phenomenology argumentations • Hermeneutics: attempts to keep experience, meaning and subjectivity in educational/social research • Hermeneutics’ quality premises: Authenticity: Trustworthiness: Credibility/dependability: Reflectivity: (See Flick 2002; Holliday 2002) Dereje Tadesse Birbirso (PhD) • Drawbacks: Presupposes the existence of autonomous meaning, pre-existent to any human being Risk of anthropomorphic fallacy Dereje Tadesse Birbirso (PhD) iii. Realist argumentations • Realism/Critical realism: an attempt to explain mechanisms operating independently of us researcher; Truth lies in the mechanisms Our observation of mechanisms depend upon our conceptual framework and, hence, of social origin Dereje Tadesse Birbirso (PhD) Realist quality premises: • Triangulation/openess of Conceptual frameworks Methods Actions v. words A (an) subject/individual/event v. others OR: Dereje Tadesse Birbirso (PhD) • Attuning to 3C: Coherence among research paradigm v. design v. methodology v. strategy v. methods v. analysis Consensus: subjecting the whole research process and product to rational judgement, debates, reflection, refining Correspondence: Whether the finding/data corresponds /explains the real mechanism out there, ho it operates Dereje Tadesse Birbirso (PhD) • Challenge: Is correspondence view of truth possible??? [This is rather a limit to epistemology and methodology rather than critical realist philosophy] Dereje Tadesse Birbirso (PhD) 5.RESEARCH METHODS Research Methods: 1) In quantitative design refers to instruments of data collection and analysis 2) In qualitative design refers to methods or techniques or tools of data gathering (and) analysis Dereje Tadesse Birbirso (PhD) In qualitative (or educational and social) research, method: • Data collection and analysis overlap • Researching and teaching (training) seamlessly flow • Theorizing and practising feed and charge each other • Method of collection can simultaneously be method of training/teaching • Naturalistic (un-/non-structured, ‘informal’) • Dialogical to the researched—context, subjects, self Dereje Tadesse Birbirso (PhD) Key methods in social and educational research: 1. Participant observationa naturalistic field strategy that simultaneously combines: document collection (of national, official, individual participants’ [e.g. diaries]) interviewing (of respondents and informants), direct participation (of the researcher and respondents and informants) and Observation (by the researcher, colleagues & an informant (i.e. a key participant) introspection (reflective/analytic memoes/accounts (written & spoken) by both the researcher and respondents and informants, e.g. reflective journaling) (Denzin 1989 in Flick 2002: 139) Dereje Tadesse Birbirso (PhD) NB: Read for yourself on the following methods: • Interview (of many types) • Observation (of many types) • Diaries • Reflective journals • Checklists • Recordings (video, tape, photographs) • Questionnaire (of many types), etc, etc. Dereje Tadesse Birbirso (PhD) 6. DATA ANALYSIS & WRITING UP/REPORTING OF YOUR RESEARCH I. ‘Tale’ types (van Mannen 1978): 1. Positivist or ‘realist tales’—the traditional approach with the emphasis on realism and objectivism, with the writer adopting a detached, omniscient stance, and employing ‘scientific’ criteria to validate the research; Dereje Tadesse Birbirso (PhD) 2. ‘Confessional tales’--where writers actually see themselves as part of the research act and make ‘confessions’ about the problems and limitations of their research methods and their own actions as researchers. Dereje Tadesse Birbirso (PhD) 3. ‘Impressionist (postmodernist) tales’-- which are much more concerned about giving voice to others in the research, those who might be regarded as ‘subjects’ of the research in realist tales. E.g., use a range of literary devices to evoke situations and experiences, arouse feelings as well as stimulate thought, and to celebrate differences, numerous and changing realities, incompleteness and partiality Dereje Tadesse Birbirso (PhD) II. Research Structure (Woods 1999; Cresswell 2007): i. Research structure 1. Positivist structure (objectivist introduction-literatureresults--conclusion reporting) 2. Narrative structure (interpretive story teller) 3. Phenomenological structure (descriptive/interpretive) 4. Grounded theory (critical realist explanation of themes and categories) 5. Ethnographic (social constructivist story teller) 6. Case study (transformative action research/practitioner inquiry teller headed by reflective questions) Dereje Tadesse Birbirso (PhD) ii. Rhetorical structures treatment of relation of voices (researcher’s, participants’), theories (quotes), audience, etc 1. Embedded structure (emphasis on and guided by data segments/texts/tools) 2. Constant comparative structure (emphasis on and guided by themes as they emerge) Dereje Tadesse Birbirso (PhD)
