Research l.jpg

Research...

  • The systematic application of a family of methods employed to provide trustworthy information about problems

…an ongoing process based on many accumulated understandings and explanations that, when taken together lead to generalizations about problems and the development of theories


The basic steps of research l.jpg

The basic steps of research...

Scientific and disciplined inquiry is an orderly process, involving:

recognition and identification of a topic to be studied (“problem”)

description and execution of procedures to collection information (“method”)

objective data analysis

statement of findings (“results”)


Types of research l.jpg

Types of research...

Basic…

…the process of collecting and analyzing information to develop or enhance a theory


Slide5 l.jpg

Applied…

…conducted for the purpose of applying or testing theory and evaluating its usefulness for solving problems


Slide6 l.jpg

Evaluation…

…concerned with making decisions about the quality, effectiveness, or value of programs, products, or practices


The research continuum l.jpg

The research continuum…

field

laboratory

evaluation research

pure research

APPLIED

BASIC

current problems

theory development

what works

why it works

produces concepts

provides data


Approaches to reasoning l.jpg

Approaches to reasoning...

Inductive…

…developing generalizations from a limited number of specific observations or experiences

…highly dependent on the number and representativeness of the specific observations used to make the generalization


Slide9 l.jpg

Deductive…

…developing specific predictions from general principles, observations, or experiences

…dependent on the truth of the generalizations used as a basis for its logic

QUANTITATIVE

researcher intersubjectivity

researcher objectivity

post-structuralism: depth

logical positivism: factual

“snapshot”

“portrait”


Research methods l.jpg

Research methods...

Quantitative…

…collects and analyzes numerical data obtained from formal instruments


Slide12 l.jpg

Qualitative…

…collects and analyzes nonnumeric data over an extended period of time to situate meaning within a particular perspective or context


Quantitative methods l.jpg

Quantitative methods...

  • descriptive research (“survey research”)

  • correlational research

  • causal-comparative research (“ex post facto research”)

  • experimental research


Slide14 l.jpg

  • descriptive research (“survey research”)

…collects data in order to answer questions about the current status of the subject or topic of study

…uses formal instruments to study preferences, attitudes, practices, concerns, or interests of a sample


Slide15 l.jpg

  • correlational research

…determines whether and to what degree a relationship exists between two or more variables

…the presence of a correlation does not indicate a cause-effect relationship primarily due to multiple confounding factors

Slide21 l.jpg

  • causal-comparative research (“ex post facto research”)

…at least two different groups are compared on a dependent variable or measure of performance (called the “effect”) because the independent variable (called the “cause”) has already occurred or cannot be manipulated


Variable l.jpg

Variable...

…a concept (e.g., intelligence, height, aptitude) that can assume any one of a range of values


Research variables l.jpg

Research variables...

Independent…

…an activity or characteristic believed to make a difference with respect to some behavior

…(syn.) experimental variable, cause, treatment


Slide24 l.jpg

Dependent…

…the change or difference occurring a a result of the independent variable

…(syn.) criterion variable, effect, outcome, posttest


Slide25 l.jpg

  • experimental research

…the researcher selects participants and divides them into two or more groups having similar characteristics and, then, applies the treatment(s) to the groups and measures the effects upon the groups


Quantitative method decision tree l.jpg

Quantitative method decision tree…

Is there a cause-effect relationship?

YES

NO

Is the independent variable manipulated?

Is there a relationship or prediction being made?

YES

NO

YES

NO

Experimental

Causal-Comparative

Correlational

Descriptive


Qualitative methods l.jpg

Qualitative methods...

  • historical research

  • grounded theory

  • ethnography

  • phenomenology

  • ethology

  • case study

  • ethnomethodology

  • action research

  • symbolic interaction


Slide28 l.jpg

  • historical research

…studies available data to study, understand, and interpret past events


Slide29 l.jpg

  • ethnography

…studies cultural patterns and perspectives of participants in their natural settings


Slide30 l.jpg

  • ethology

…compares the origins, characteristics, and culture of different societies


Slide31 l.jpg

  • ethnomethodology

…studies how people make sense of their everyday activities in order to behave in socially accepted ways


Slide32 l.jpg

  • symbolic interaction

…investigates how people construct meaning and shared perspectives by interacting with others


Slide33 l.jpg

  • grounded theory

…investigates how inductively-derived theory about phenomenon is grounded in the data of a particular setting


Slide34 l.jpg

  • phenomenology

…considers how the experience of particular participants exhibits a unique perspective


Slide35 l.jpg

  • case study

…examines the characteristics of a particular entity, phenomenon, or person


Slide36 l.jpg

  • action research

…practitioner-based systematic reflection upon practice aimed at improving professional practice


Slide37 l.jpg

Generally speaking, qualitative researchers….

…spend a great deal of time in the settings being studied (fieldwork)

…rely on themselves as the main instrument of data collection (subjectivity; intersubjectivity)

…analyze data using interpretative lenses


Slide38 l.jpg

…employ expressive language and voice in descriptions and explanations

…seek depth of perspective (i.e., “waves of data” requiring ongoing interpretation)

…judged in terms of believability, trustworthiness, coherence, and logic of interpretations


Types of criticism l.jpg

Types of criticism...

Internal…

…evaluates the worth or trustworthiness of the content of the data

External…

…assesses the authenticity of the data source


Slide40 l.jpg

  • data sources…

…primary

…secondary

…tertiary


Limitations of the scientific and disciplined inquiry approach l.jpg

Limitations of the scientific and disciplined inquiry approach…

  • not able to investigate philosophical and/or moral/ethical problems (“shoulds” and “oughts”) only factual matters

  • the presence of intervening and confounding variables make assertions probable rather than proven

  • imperfections in sampling, instruments, procedures
