KNR 295 Honors Seminar Introduction Slide 1 Introduction to research Part one: Foundations
2
KNR 295 Honors Seminar: Introduction Slide 2 Today... 1. General goals of the course Objectives (what do I want to achieve?) Research and its place within undergraduate education Assessment methods (what sort of practice of required skills will I provide, and what sort of skills will be expected of you?) Understanding and mastering course content Bloom’s taxonomy 2. Introductory lecture/discussion/questions Following Trochim’s chapter 1 - Foundations 3. For next week: Reading assignment & Questions
3
KNR 295 Honors Seminar: Introduction Slide 3 A couple of examples 1. Card trick Card trick 2. Guess my rule
4
KNR 295 Honors Seminar: Introduction Slide 4 Foundations of research Trochim’s Yin/Yang map TheoryPractice
5
KNR 295 Honors Seminar: Introduction Slide 5 Foundations of research Types of studies Three basic types: Descriptive Relational Causal Time in research Cross-sectional vs. longitudinal designs Repeated measures vs. time series designs
6
KNR 295 Honors Seminar: Introduction Slide 6 Foundations of research Types of relationships Their nature Correlation and Causality Mediation/Moderation Patterns of relationships None/positive/negative/curvilinear
7
KNR 295 Honors Seminar: Introduction Slide 7 Foundations of research Variables Value or attribute = a property of something (may or may not be numeric) examples: Your age My age Your gender My gender Variable How about all our ages? We all have an age, but they are all different Age is something we vary by Age is a variable that describes a property of our group
8
KNR 295 Honors Seminar: Introduction Slide 8 Foundations of research Variables Independent variable What you or nature manipulates in some way E.g. 1: What happens when you get older? Age is the independent variable (nature is the manipulator) E.g. 2: What happens when you drink? Blood alcohol level is the IV (you are the manipulator) Critiquing IVs: Exhaustive? Mutually exclusive attributes? See also construct validity (later)
9
KNR 295 Honors Seminar: Introduction Slide 9 Foundations of research Variables Dependent variable The thing that is influenced (changed) by your independent variable E.g. 1 (IV = Age): Skin sag, baldness, frequency of urine expulsion, memory strength E.g. 2 (IV = Alcohol consumption): Balance, inhibition, frequency of urine expulsion Critiquing DV’s: see operationalization, reliability, measurement validity (all later)
10
KNR 295 Honors Seminar: Introduction Slide 10 Foundations of research Hypotheses A specific statement of prediction Inductive vs. deductive research Deductive has ‘em, inductive often doesn’t Types Alternative vs. null One-tailed vs. two-tailed Hypothetical-deductive model 2 mutually exclusive statements (null, alternative) Tests designed to specify which can be rejected and which cannot
11
KNR 295 Honors Seminar: Introduction Slide 11 Foundations of research Types of data Qualitative vs. quantitative More a case of philosophical difference than numerical difference (in the better debates, at least) The unit of analysis Group vs. Individual vs. Artifact vs. Geographical unit vs. Social interaction Hierarchical modeling
12
KNR 295 Honors Seminar: Introduction Slide 12 Foundations of research Fallacies A variety of errors of either logic or premise strength that can result in weak arguments being formed. Beyond the remit of this course, but very important nonetheless for good research papers
13
KNR 295 Honors Seminar: Introduction Slide 13 Foundations of research Philosophy of research Structure of research
14
KNR 295 Honors Seminar: Introduction Slide 14 Foundations of research Structure of research Components of a study Research Problem Research Question The treatment (or program/event – the purported cause) The sample (the unit) The outcome (purported effect of treatment) The design
15
KNR 295 Honors Seminar: Introduction Slide 15 Foundations of research Deduction vs. induction Deduction Induction
16
KNR 295 Honors Seminar: Introduction Slide 16 Foundations of research Positivism vs. post-positivism Positivism Science can only address that which is directly observable Observation and measurement is the only means to the truth Post-positivism & critical realism Simply put… all measurements are potentially faulty Truth, though it exists, is unlikely to ever be known with certainty The point of science is to maintain the search for the truth despite knowing that one may never reach it Hence seek reality, while being critical of one’s current estimation of it
17
KNR 295 Honors Seminar: Introduction Slide 17 Foundations of research Post-positivism & critical realism Because we are critical of our grasp on reality, we Take multiple measures Critique the measures we have Engage in hearty arguments about our perspectives and their influence on our thought processes (that we might not be aware of) It is only through such critique that objectivity can be approximated – an individual cannot be objective, but if a viewpoint is generalizable across many perspectives and cultures it may possess some objectivity
18
KNR 295 Honors Seminar: Introduction Slide 18 Foundations of research Post-positivism & critical realism The “natural selection theory of knowledge” That which survives can claim a degree of objectivity or approximation to the truth Here lies the value of research that we do, and the criticism to which we subject it It’s pretty much the only way that our (eventual) understanding can claim a degree of objectivity (according to critical realism, that is…now, if you’re a relativist…)
19
KNR 295 Honors Seminar: Introduction Slide 19 Foundations of research Validity the best available approximation to the truth* of a given proposition, inference, or conclusion (*allows for criticism –this is where we come in) What you wish to say within a study (& therefore the kinds of validity you are going to claim) depends on the type of study you are conducting (see slide 5)
20
KNR 295 Honors Seminar: Introduction Slide 20 Foundations of research Validity Operationalization
21
KNR 295 Honors Seminar: Introduction Slide 21 Foundations of research Validity
22
KNR 295 Honors Seminar: Introduction Slide 22 Foundations of research Validity For each validity type there are typical threats, and ways to reduce them (we deal with these in later weeks) This gives us a framework within which to critique the overall validity of our (or any other) study
23
KNR 295 Honors Seminar: Introduction Slide 23 Foundations of research Ethics Protect participants vs. Deprive others of knowledge A tricky balance One problem is that we are notoriously untrustworthy as a species (see Milgram, Tuskagee, Stanford prison experiments on web), suggesting the need for strong ethical procedures Another is that strong ethical procedures can deprive individuals of free will
24
KNR 295 Honors Seminar: Introduction Slide 24 Foundations of research Ethics Institutional Review Boards Informed Consent these are the ways we currently constrain our practices to keep them “ethical”
25
KNR 295 Honors Seminar: Introduction Slide 25 Foundations of research Conceptualizing research How do you get started/develop and idea/formulate a research plan/conceptualize and area of research? All this is really for those who wish to conduct research For now, I’d rather focus on a framework for understanding and critiquing the research that already exists – we’ll get to the doing stage if time allows (for now, assume that the tried and tested method of asking a faculty member for a question is the best method)
