Course Organization & Handouts
• Syllabus & Outline of Class Sessions
– Objectives
– Course Administration (textbook, grading, office
hours)
– Tentative Schedule of Class Sessions

Course content
• Introduce different forms of research
• Analyze relationships between goals,
assumptions, theories and methods
• Study basic data collection and analysis
techniques
• Research process—focusing on empirical
methods
Why study methods? Practical aspects
– learn to read other people’s research & critically
evaluate it
– learn ways to find your own “data” to answer your
own research questions
– acquire skills potential employers seek
– self-defense (against misinformation) &
responsible citizenship
Importance of research in everyday life
& in communications studies
• civil society --Interpersonal & intercultural
relations
• policy decisions about “life and death” issues
(student loans, health care, welfare benefits…etc
• healthcare (evidence-based medicine), Personal
identity and ideas about society
• industry and marketing decisions (choices of
products in stores, cable channels, opinion polls
etc..)
• …..MORE…..
The
Research
Process
Babbie (1995: 101)
Why study methods?
– “Knowledge is power” (to acquire skills for social
action or change)
• “Savoir pour pouvoir, Pouvoir pour prévoir” (Auguste
Comte)
• «To know to do (have power), to do (have power) in order
to predict the future and plan for it »
– « Knowledge is understanding »
• “décrire, comprendre, expliquer ” (Gilles Gaston Granger)
• “to describe, to understand and to explain”
Research has the potential to inform
and misinform
• even well-done research is not always used
accurately
• some research is technically flawed
• knowledge of methods an important tool for
understanding logic and limits of claims about
research
Research Methodology (Scholarly
Perspectives)
• Process
– methods
– logic of inquiry (assumptions & hypotheses)
• Produces
– laws, principles and theories that can be tested
• (Karl Popper & notion of falsifiability for politically
engaged scholars interested in the fight against
genocide in the early 20th century)

Other Ways of Knowing
– authority (parents,
teachers, religious
leaders, media gurus)
– tradition (past
practices)
– common sense
– media (TV. etc.)
– personal experience

Ordinary Inquiry vs. Scholarly Inquiry
Risks of “Errors” associated with non-scholarly
knowledge
• selective observation--only notice some phenomena-miss others
• overgeneralization-evidence applied to too wide a range
of conditions
• premature closure--jumping to conclusions
• halo effect--idea of being influenced by prestige
Types of “Disciplines” (in history)
• Ranking of disciplines (are they scientific or
not?)
• Middle ages– education as preparation for
careers in theology
– trivium (studied first, language skills)
• logic rhetoric, grammar
– quadrivium
• arithmetic, geometry, music, astronomy
Ranking Disciplines: Positivist ideas
(Auguste Comte)

Communication as a Science?
• Field more recent
– affiliations with the sciences, social sciences & the
humanities
• Scholarly work (like old ideas of science)
distinguished from mythology by methods
AND goals
• many different approaches
Relations between theory and empirical
observation
• Theory and empirical research
– Testing theories through empirical observation
(deductive)
– Using empirical observation to develop theories
(Inductive)

Scholarly Communities--Norms
• universalism -- research judged on “scientific”
merit
• organized scepticism -- challenge and question
research
• disinterestedness-- openness to new ideas,
non-partisan
• communalism--sharing with others
• honesty
Scholarly Publications vs. Other
publications
• peer review
– by knowledgable people
– “blind” peer review
• referees don’t know who did it
• authors don’t know who refereed it
– unpaid
Research Questions
• Questions researchers ask themselves, not the
questions they ask their informants
• Must be empirically testable
• Not
– too vague
– too general
– untestable (with implicit, untested assumed outcomes)
Using literature reviews to develop ideas
for topics
• Literature review = Survey of research done on
your topic.
• May be used to
• previous research may inspire you to:
–
–
–
–
replicate a project (exactly or with variations)
explore unexpected findings
follow suggestions for further research
extend explanation or theory to new topic or setting or
context
– challenge findings-- try to refute conclusions
– look for new variables, relationships not treated in
literature
Developing research topics
Research Paradigms
• Sets of shared patterns in a scholarly
community about what constitutes
worthwhile research (Thomas Kuhn, The
structure of scientific revolutions, 1968)
– What problems are worth investigating?
– What constitutes an answer?
• Different views on how approaches are
grouped
dentifying Styles of Research: Example of Quantitative vs. Qualitative
Approaches
(Common about 20-30 yrs ago but still used. .Textbook Chapter 13)
Quantitative
Objective
Variables
Reliability
Value-Free
Independent of Context
Many cases or subjects
Statistical Analysis
Detached Researcher

Qualitative
Subjective
Processes and events
Authenticity
Explicitly Stated Values
Aware of Content

Another idea: Four Paradigms (Burrell
& Morgan)
radical humanist
interpretive
radical structuralist
functionalist
Order/stability/regulation

Exploratory Research
• When not much is known about topic
• Surprises (e.g. Serendipity effect)
• Acquire familiarity with basic concerns
and develop a picture
• Explore feasibility of additional
research
• Develop questions
Descriptive Research
• Focuses on “who”, “what” and “how”
• Background information, to stimulate new
ways of thinking, to classify types, etc.
Explanatory Research
• To test theories, predictions, etc…
• Idea of “advancing” knowledge
Intended Use of Study
• Basic
• Applied
– action research (We can make a difference)
– social impact assessment (What will be the
effects?)
– evaluation research (Did it work?)
– needs assessment (Who needs what?)
– cost-benefit analysis (What is it worth?)
Basic or Fundamental Research
• Concerns of scholarly community
• Inner logic and relation to theoretical issues
in field
Applied Research
• commissioned/judged/used by people outside
the field of communication
• goal of practical applications
– usefulness of results
Types of Applied Research


Action Research
Social Impact Assessment
Needs Assessment
Evaluation Research
• formative (built in)
• summative (final outcomes)
 Cost-benefit analysis
Treatment of Time
 Cross-sectional
(one point in time)
 Longitudinal
(more than one point in time)
Main Types of Longitudinal Studies
•
Panel study
– Exactly the same people, at least twice
•
Cohort Analysis
– same category of people or things (but not exactly same individuals) who/which shared an
experience at at least two times
– Examples: Birth cohorts. Graduating Classes, Video games invented in the same year
2000

•
Time-series
– same type of info., not exactly same people, multiple time periods, e.g. Same place
2006
Burnaby residents
•
2011
Burnaby residents
Case Studies may be longitudinal or cross-sectional
Lexis Diagram (To study Cohort
Survival)
Units of Analysis
• Examples
– Individual people
– Newspaper articles or broadcasts
– Individual video games
Units of Analysis
– Families, Sports Sections etc.
Units of
analysis:
• Examples:
– Households
– News networks
(Al Jazeera,
Channel News
Asia, CNN)
Importance of Choosing Appropriate Unit
of Analysis
• example: Ecological Fallacy (cheating)
Ecological Fallacy
Ecological Fallacy
Ecological Fallacy & Reductionism
ecological fallacy--wrong unit of analysis
(too high)
reductionism--wrong unit of analysis (too low)
reductionism--wrong unit of analysis (too low)
