• Introduction to research process

• prepare the research proposal

• Writing the research report

Page 3: Research process - 2013 -  for IS5232 module

• The curiosity of the human nature

leads them for investigations

• Dogma

Beginning of scientific inquiry

• Logical thinking

Page 4: Research process - 2013 -  for IS5232 module

• Scientific enquiry began with the

curiosity of human nature and logical

thinking towards the natural existence

of the universe and against the teaching

of religious Dogmas. of religious Dogmas.

The first systematic approach to reasoning

e.g. Major premise – All men are mortal

Miner premise- I am a man

Conclusion- I am mortal

Deductive reasoning

Page 6: Research process - 2013 -  for IS5232 module

Inductive reasoning

Specific premises 1 - Nimal, Wikki, John and Piyal attended class regularly

Specific premises 2 - Nimal, Wikki, John and Piyal received high score of marks

Conclusion - Attending class regularly results in high score of marks

Page 7: Research process - 2013 -  for IS5232 module

Deductive-Inductive reasoning

– Deductive-Inductive reasoning process involves the integration

of both above to find a solution to the problem.

• Problem

• hypothesis• hypothesis

• Collection, organization and analysis of data

• conclusions

• Verification, rejection or modification of hypothesis

Scientific approach

What is Research

• Research is all about addressing an issue or asking

and answering a question or solving a problem.

• We do problem solving in our day-to-day life

informally.

• Yet, to be a research it should follow scientific

method which is more formal, systematic and

carefully analyzed.

Page 9: Research process - 2013 -  for IS5232 module

• Research is a structured enquiry that

utilizes acceptable scientific methodology

to solve problems and create new

knowledge that is generally applicable.

Page 10: Research process - 2013 -  for IS5232 module

Types of Research – mode of application

• Fundamental or Basic research

• Applied research• Applied research

• Action Research

Page 11: Research process - 2013 -  for IS5232 module

• Fundamental research is usually carried on in a

laboratory or other sterile environment, some times

with animals.

Fundamental research

• This type of research which has no immediate or

planned application may later result in further

research of applied nature.

• In behavioral science, Fundamental research may be

concerned with the development and testing of

theories of behavior.

Page 12: Research process - 2013 -  for IS5232 module

• Applied research has most of the characteristics of

fundamental research.

• The purpose is to improve the product or process -

Applied research

• The purpose is to improve the product or process -

testing theoretical concepts in actual problem

situations.

Page 13: Research process - 2013 -  for IS5232 module

• Action research is focused on immediate application,

not on the development of a theory or on general

application. Its findings are to be evaluated in local

applicability.

• Solution of problems in a particular setting

Page 14: Research process - 2013 -  for IS5232 module

Types of research - objectives

• Design the research• Design the research

• Collection, organization and analysis of data

• Formulation of conclusions

• Verification, rejection or modification of hypothesis

by the test of its consequences in a specific situation.

Page 17: Research process - 2013 -  for IS5232 module

Identification of the problem

– Observation.

Problems are all around us. Research problems can

be identified through:

– Literature reviews.

– Professional conferences.

– Contacting experts.

undergraduates during IL lectures

Page 21: Research process - 2013 -  for IS5232 module

Activity 1

• Narrow down your broad topic to form a

researchable topic.

Problem :There are road accidents much more

than ever. There are various reasons for

increasing of road accidents. One may be the

use of alcohol by drivers during driving. It

should be researched to find out whether there

is an effect of alcohol use on accidents.

• Time - 5 minutes

Page 22: Research process - 2013 -  for IS5232 module

relationship between two or more

variables

Page 50: Research process - 2013 -  for IS5232 module

Significance of the problem

• Researcher points out how the solution to the

problem can influence the society.

• Justify the worthiness of the study

• Background information may be useful here

Page 51: Research process - 2013 -  for IS5232 module

• The findings of the study will be beneficial to

undergraduates, librarians, and administration of

the university.

If the Kuppi is effective, librarians can facilitate the

students with study places and essential resources.

If it is not effective academics and librarians can

launch programmes to convince and encourage launch programmes to convince and encourage

students to follow effective methods of learning.

the researcher.

• Delimitations are the boundaries of the study.

Page 53: Research process - 2013 -  for IS5232 module

Definitions

• Kuppi

Kuppi is a type of studying techniques used by

college students. Similar term used for cramming

in universities.

• Performance level

the term Performance level here refers to the score the term Performance level here refers to the score

of marks in semester examinations.

Page 54: Research process - 2013 -  for IS5232 module

Assumptions

• Some group discussions among students were

similar to Kuppi. Sometimes it is difficult to

distinguish kuppi from group studies.

Page 55: Research process - 2013 -  for IS5232 module

Limitations

• Group discussions among students were not

considered as Kuppi in this study because group

discussion is one of accepted effective study

techniques.techniques.

Page 56: Research process - 2013 -  for IS5232 module

Delimitations

• This study involves the Kuppi activities of

engineering students of UR only.

• Only first year and final students were selected.

Page 57: Research process - 2013 -  for IS5232 module

Review of related literature

• Summary of previous research

• What is already known and what is still unknown and

untested

• Provides a background for the study

• Make the reader aware of status of the issue• Make the reader aware of status of the issue

Literature review is a valuable guide to defining the

problem, recognizing its significance, suggesting

data gathering devices, appropriate study

design, and formulating hypothesis.

Page 58: Research process - 2013 -  for IS5232 module

Hypothesis

H1

Kuppi classes among undergraduate students can make a

significant effect on MCQ papers than essay type papers.

H2

Systematic learning is more significant in earning higher GPA than

Kuppi learning among engineering undergraduates. Kuppi learning among engineering undergraduates.

Page 59: Research process - 2013 -  for IS5232 module

• The main purpose of this study is to investigate

whether ‘Kuppi’ classes can make a significant

effect on the achievement of higher score in

examinations.

• Supportive objectives:

• Explore who engage in Kuppi classes

• Explore the contents of Kuppi classes

• Calculate the score of marks in exams who engage

in Kuppi classes

• Compare and contrast the score of Kuppi- engaged

students and non Kuppi- engaged students.

Page 60: Research process - 2013 -  for IS5232 module

Methodologies

Experimental design

First year First year

Final year Final year

Page 61: Research process - 2013 -  for IS5232 module

• Pre-test

All four groups will be given two question papers

Specially funding agencies require a well planed

research proposal before granting the fund.

There are several parts in a typical research

proposal although not compulsory.

The proposal should be well planed so that the

funding agency can be convinced the importance

Preparation of the Research

report

• After you conducting the research you have to

communicate your finding with the relevant

community.

• Writing the research report is the last and (for many

people) the most difficult step in the research process.

The purpose of the research report is to inform the

world about what you have done, how you have done

it, and what you have discovered.

• Following factors are important to

consider when you write the research

report:

– Value of the content

– Organization of the content– Organization of the content

– Structure of presenting ideas

– Language and style

Page 67: Research process - 2013 -  for IS5232 module

your research report is based on

following questions.

• What was the research problem?

• Why is this problem important?

• How does your project relate to the context of

other research?other research?

• How did you investigate the research problem?

• What are your findings?

• What do these findings tell you?
