Trang 3What are the differences between qualitative and quantitative method?
What are the major research methods?
Trang 4The differences between qualitative
and quantitative methods :
Qualitative Methods Quantitative Methods
Collecting non-numeric data Collecting numerical data that can
be quantified Methods include focus
groups, in-depth interviews,
and reviews ,content
analysis,observation
Methods include questionnaire surveys,reviews, content
analysis,observation
This is an inductive process
which is used to formulate
theory.
This is a deductive process which
is used to test pre-specified concepts, constructs, and hypotheses that make up a theory
It describes a problem or
condition from the point of
view of people experiencing it
it provides observed effects of a program on a problem or
condition
Trang 5( Qualitative Methods ) ( Quantitative Method )
Can be valid and reliable:
depends on the measurement device or instrument
Take less time on the
planning end and more time
during the analysis process
Take more time on the planning end and less time during the analysis process
Less generalizable More generalizable
Trang 8• It is a research project by looking at
sources like encyclopedias and other reference books, CD-ROMs, community surveys, government reports and
Australian Bureau of Statistics (ABS)
data.
Trang 9• Tell us what is already known about your research area.
• These information you collect will be both qualitative and quantitative.
Trang 10It is used for historical research
FOR EXAMPLE: create a new kind of medicine , a new machine for
education,agriculture,Industry
Trang 11It is a method which we carry out
interviewing small number of people
(ten or less) from whom you need a lot
of detailed information, consider using individual in-depth interviewers
Typically we would develop a list of
open-ended questions and base your interview around these.
Trang 12FOR EXAMPLE Hypothesis :students nowadays are lazier than ones
in the past Interview some experienced Headmasters,teachers
Trang 13A hypothesis “Students whose major is English at Tay Nguyen University are very deligent”
Interview some teachers who taught
them and ask if they agree or not
Interview some students how many time they spend for studying
Trang 14A focus group is similar to an in- depth interview but you gather the information for a small discussion group, usually up to eight people.
Trang 15For example:
We want to know if the teaching method that teacher A use is effective or not We interview about 5 groups of students in
different classes who used to learn with his method.
Trang 16They are useful for explanatory and evaluate researches
Trang 17It is a method which we use to analyze existing material such as newspapers,
historical and other documents, television programs, magazines or books.
Trang 18It is used for descriptive , explanatory and evaluative research
Trang 19If we want to analyze “climate change", you can use the information on newspapers,
historical documents
FOR EXAMPLE
Trang 20For example:
We analysize a graph which show world population growth or show the number of people who suffer from AIDS in Africa to find out how it changes and what
information we can collect.
Trang 21It is a method which we look at or observing some form of behaviour
Trang 22It is used for descriptive and evaluative research
FOR EXAMPLE
Evaluate the quality of A high school
By observing students at this high school.
Do they go to school on time?
Are they aware of protecting public
properties?
How do their attitudes towards study?
Do they follow the principles of the school?
Trang 23It is the method that we participate in what we are researching
Trang 24It is used for descriptive and evaluative research
For example
Evaluating the food quality of a restaurant,we
participate in observing the way the chefs cook
Trang 25For example
Evaluating the food quality of a restaurant,we
participate in observing the way the chefs cook
A research: The differences about lifestyle between peole living in rural areas and ones in urban areas
We should live those areas to observe
Trang 26It is a method that involves colleting data from a large number of people (more than forty),a
questionnaire might be worthwhile They are of two types:
+ Self-completed where we hand out and mail the questionnaire
+ Researcher –completed where we ask the
questions and complete the form ourselves
Trang 27It is used for descriptive ,explanatory,and
evaluative forms of research
For example
We can hand out a list of questions to survey the way students use to improve listening skill everyday
Trang 29It is a method that involves testing a hypothesis
Trang 30It is used for explanatory and evaluative research
