9. Research: A Definition
• Research:
– Is an activity that contributes to the understanding
of a phenomenon [Kuhn, 1962; Lakatos, 1978]
• phenomenon: a set of behaviors of some entity(ies) that is found
interesting by a research community
• understanding: knowledge that allows prediction of the behavior
of some aspect of the phenomenon
• activities considered appropriate to the production of
understanding (knowledge) are the research methods and
techniques of a research community
10. Research vis Project
• Research is always end with creation of new
knowledge
– Knowledge which does not existing in the existing
literature
– The process of exploring the unknown, studying
and learning new things, building new knowledge
about things that no one has understood before -
that is what we think of as performing research
11. Research vis Project …
• Project is not expected to create new
knowledge but
– It must solve a problem using existing knowledge
– Developing a database for an organization is
considered as a project work
– What is about developing an information
system for an organization?
12. Theory
• An abstraction about the behavior of the phenomena
that serve as a guide for future practice
• It is an association of two or more constructs
• Theories are developed based on what is observed or
experienced, often times in the real world.
• Theory is not an absolute truth
• It is a changing truth as we investigate new facts and
observe new relationship
13. Theory – Example
• Learning theory has different theories
– Behavioral theory based on stimulus –response
association
– It states that a behavior that is reward will have high
probability to be repeated while a behavior that is
punished will be diminished
– Its application for practice is that
• When students rewarded in the class for doing good, they
will retain and reapply that behaviour
• Punishment for late comer students discourages that
behaviors from repeating other time
14. Theory …
• Technology acceptance theory
• This theory explains what makes a new
technology acceptable or successful
• It states that a technology which is useful and
easy to use will be acceptable by end users.
15. Scientific Approach
• Research is a science that follows scientific methods
• Science is the systematic study of the properties of the
physical world,
– by means of repeatable experiments and
measurements, and
– the development of universal theories that are
capable of describing and predicting observations.

16. Research as Scientific Method
• The scientific method is a way to ask and
answer scientific questions by making
observations and doing experiments.
18. Significance of Research
• In what way(s) does your study add
significant contribution(s) to:
– Extant Theory?
– Relevant Practice?
19. Definitions of Terms
• Define each technical term as it is used in relation
to your research project.
– Resource – how is defined in the context of library and
computer system
• This helps remove significant ambiguity from the
research itself by ensuring that reviewers, while
they may not agree with your definitions, at least
know what you’re talking about.

20. Types of Research
1. Basic Research
its main purpose is the disclosure of fundamental
truths or principles
Focuses the testing and development of theory
To extend existing human understanding
Has no immediate application to real world problems
Example -
Physics is interested to understanding basic elements
that make up matter
Systems theory
21. Cont’d
2. Applied research
–To solve existing societal problems
–Example -
• Undertaking research to solve user resistance
problem for new information system
• Developing a SW that is used for payroll
processing
• developing e-learning package to enhance
student learning
23. Research Proposal
• It is the blue print of the entire research process
• It describes the main components of the research
• Helps the researcher to systematically and effectively
execute the research project
• It indicates the feasibility of the research project
before much effort and investment is made
• It is also prepared to acquire research fund from
sponsors
• It should be done with care in order to get rejected the
proposal

25. Title
• It should be concise and descriptive. For example, the
phrase, "An investigation of . . ." could be omitted.
• Often titles are stated in terms of a functional
relationship, because such titles clearly indicate the
independent and dependent variables.
• Think of an informative but catchy title. An effective
title not only pricks the reader's interest, but also
predisposes him/her favorably towards the proposal.
• E.g. change without change
26. Abstract
• It is a brief summary of approximately 300
words.
• It should include the research question, the
rationale for the study, the hypothesis (if any),
the method and the main findings.
Descriptions of the method may include the
design, procedures, the sample and any
instruments that will be used.
27. Introduction
• The introduction typically begins with a general
statement of the problem area, with a focus on a
specific research problem, to be followed by the
rational or justification for the proposed study. The
introduction generally covers the following elements:
1. State the research problem, which is often referred to
as the purpose of the study.
2. Provide the context and set the stage for your research
question in such a way as to show its necessity and
importance.
3. Present the rationale of your proposed study and
clearly indicate why it is worth doing.
28. Cont’d
4. Briefly describe the major issues and sub-problems to
be addressed by your research.
5. Identify the key independent and dependent variables
of your experiment. Alternatively, specify the
phenomenon you want to study.
6. State your hypothesis or theory, if any. For exploratory
research, you may not have any hypotheses.
7. Set the delimitation or boundaries of your proposed
research in order to provide a clear focus.
8. Provide definitions of key concepts. (This is optional.)
29. Method – Example of Quantitative
• Design -Is it a survey study or a laboratory
experiment? What kind of design do you choose?
• Subjects or participants - Who will take part in your
study ? What kind of sampling procedure do you use?
• Instruments - What kind of measuring instruments
or questionnaires do you use? Why do you choose
them? Are they valid and reliable?
• Procedure - How do you plan to carry out your
study? What activities are involved? How long does it
take?
30. Results
• Obviously you do not have results at the
proposal stage.
• However, you need to have some idea about
what kind finding you get from your research.
Describe the expected research or design
outputs
• It is used to evaluate your success or failure
