I. WHAT IS RESEARCH?
10
RE
SEARCH
11
Old French word “cerchier”, meaning to search or seek.
The word “re” means again.
So, the search is done many times.
12
Why Re? Why do so many times?
To be sure ……To be certain ……
…………that something really occur…………that something really happen…………that a phenomena really exist
13
Through repetitive experiments:
Madame Curie discovered radium.Alexander Graham Bell --- telephone.Wright Brothers --- aeroplane.Other examples?
14
Basicly, the word research means:
StudyExplorationExaminationInvestigationInquiry
What is Research?
15
Research is a / an ……….……. seeking activity investigation facts finding discovering activity solving problem activity data collection activity establishing empirical evidence structured activity using the scientific
method
Research Concept
16
II. DEFINITION OF RESEARCH BY PAST SCHOLARS
17
Scholar Meaning Kerlinger (1973) An effort to analyze data using the scientific method
in a formal and systematic way. Its purpose is to find answers to questions or problems.
Grosof & Sardy (1985) Proces, prosedure, or strategy using the scientific method.
Touliatos and Compton (1988)
An effort in discovering new ideas, describing situations and events, as well as describing phenomena.
Ahmad Mahdzan(1992) Systematic method used by humans to increase knowledge.
Salkind (1994) A process of discovering new knowledge.
Barbie (2001) An investigation using the scientific method that is frequently used by human to describe/predict events or future happenings.
18
III. PHILOSOPHY OF RESEARCH
19
PHILOSOPHY OF RESEARCH
The term philosophy derives from a combination of the Greek words
philos = lovesophia = wisdom
Nature of knowledge and belief.
In research the concerned is on the investigation of what distinguishes mere belief from knowledge.
20
SOURCE OF KNOWLEDGE
1. INTUITIVE KNOWLEDGE2. AUTHORITATIVE KNOWLEDGE3. LOGICAL KNOWLEDGE4. EMPIRICAL KNOWLEDGE
21
1. Intuitive Knowledge belief, faith, intuition, etc. based on feelings, not hard, cold "facts."
2. Authoritative Knowledge information from people, books, a
supreme being, etc. Its strength depends on the strength of
these sources.
22
3. Logical Knowledge based on reasoning from "point A" (which is generally
accepted) to "point B" (the new knowledge).
4. Empirical Knowledge based on demonstrable, objective facts
(gathered thro’ observation and/or experimentation).
23
Research often makes use of all four of these ways of knowing:
1. INTUITIVE (when coming up with an initial idea for research)
2. AUTHORITATIVE (when reviewing the professional literature)
3. LOGICAL (when reasoning from findings to conclusions)
4. EMPIRICAL (when engaging in procedures that lead to these findings)
The empirical knowledge, is what most modern research acquisition aims at establishing, which is known as empirical research.
24
IV. WHY DO WE DO RESEARCH?
25
WHY DO WE DO RESEARCH?
To discover new information.
To expand existing knowledge.
To investigate specific questions or problems
26
To validate past information
To investigate existing phenomena.
To determine new uses of, and applications for, existing goods and services.
27
It provides answers for questions like what, where, when, how and why.
Brings out information that might not be discovered in ordinary course of life
It contributes to theory and generalizations Verifies existing theories and facts.
28
May enable us to predict events Helps in establishing inter-relationships and derive
explanations Helps developing new tools, concepts and
theories to study phenomenon.
29
Research essential for Advancement of scientific knowledge and/or development of newer technologies improvement of quality of life
‘Today’s research is for tomorrow's advancement’
30
For students in social science, research is directed toward
finding, applying & interpreting data
that can promote betterment in individual and family life, and of the society.
31
V. RESEARCH CHARACTERISTICS
32
RESEARCH CHARACTERISTICS Originates with a question or problem. Requires clear articulation of a goal. Follows a specific plan or procedure. Often divides main problem into subproblems. Guided by specific problem, question, or
hypothesis. Accepts certain critical assumptions. Requires collection and interpretation of data. Cyclical (helical) in nature.

II). Objectives 1. Descriptive research2. Exploratory3. Correlational 4. Explanatory
III). Types of information sought
1. Quantitative research2. Qualitative research3. Mixed methods
35
CLASSIFICATION BY APPLICATIONPURE/BASIC (Fundamental
research)APPLIED RESEARCH
• Address theoretical issues • Produce solution to a specific issues/problem
• Expand existing knowledge • Seek additional knowledge• Explore the unknown • Solve immediate, practical
problem• Emphasize explanation • Emphasize application
• Complex methodology • Simple methodology• Seeks answers, solutions, developments, and/or uses related to topics/problems that are new & different
• Uses known information, products, and/or services
• Long-term application • Short-term application
E.G., OF PURE RESEARCH What is the strength of Malaysian familes?
Developing family strength inventory of Malaysian families.
Why does deviant behavior occur?Stimulate new ways of thinking about deviance.
36
E.G., OF APPLIED RESEARCH Factors related to adolescents’ conduct problem.
Information relevant for parents, educators, police, policy makers, etc., who are trying to prevent delinquency.
Action research, social impact assessment research are popular examples of applied research.
Most social science research are applied in nature.
37
38
CLASSIFICATION BY OBJECTIVESDescriptive Exploratory Correlational Explanatory
•Describe systematically a situation/topic of interest.
•e.g., describe the attitude of UPM students toward smoking.
•Explore areas of limited knowledge.•Feasibility/pilot study.
•May result in full study.
•Also use to develop, refine, and/or test measurement tools and procedures
•e.g., describe the prevalence of smoking amongst UPM students.
•Determine the extent of the existence of a relationship between 2 or > aspect of a situation.
•e.g., what is the relationship between smoking and the incidence of heart attack?
•Clarify why and how there is a relationship between 2 aspects of a situation.
•e.g., why cigarette smoking results in heart attack?
CLASSIFICATION BY INFORMATION SOUGHTASPECTS QUANTITATIVE QUALITATIVE
Views on the world
Assumed social facts have objective truth, removed from individual beliefs.
Assumed that truth is constructed from social, individual or group definition of a situation.
Research Purpose
Describe reason for change in social facts through measurement and objective analysis.
Emphasize more on understanding social phenomena from the perspective of the actor based on his/her participation.
Approach Use approach such as experimental or correlation that distant a person from clearly understanding social facts.
Use approach such as ethnography that can help in understanding a research situation clearly.
Researcher’s role
Researcher removes self from the subject to avoid bias.
Researchers immerse self in the research phenomena.
39

5 steps in research process:
49
I. IDENTIFYING PROBLEM
50
Research begins with a problem. This problem need not be Earth-shaking.
Identifying this problem can actually be the hardest part of research.
In general, good research projects should: Address an important question. Advance knowledge.
51
II. DEVELOPING HYPOTHESIS
52
II. HYPOTHESIS
A successful hypothesis becomes a scientific theory.
• What is a Hypothesis:
hunch or expectations that social scientists have about relationships between or among variables,
commonly but not always expressed as the expectation that variation in an independent variable will “cause” or be associated with variation in a dependent variable.
53
A hypothesis is a specific, testable prediction about what you expect to happen in your study.
For example, a study designed to look at the relationship between study habits and test anxiety might have a hypothesis that states,
“This study is designed to assess the hypothesis that students with better study habits will suffer less test anxiety.”
Unless your study is exploratory in nature, your hypothesis should always explain what you expect to happen during the course of your experiment or research.
54
CHARACTERISTICS OF HYPOTHESIS
contains at least 2 variables. states the relationship between 2 variables. stated in a simple, clear, accurate and specific
form. present the study variable in an operational
term. can be tested to determine the extend to
which it can be supported or rejected.
55
can be deduced from theory, past research or observation, thus, it must be consistent with the existing knowledge or what is already known.
provides the guide for which research strategy to use.
help to identify the type of data to be collected. help to identify which statistic to use in analyzing
data. facilitate in how to reach a conclusion in solving
the research problem.
56
FORMS & CLASSES OF HYPOTHESIS
Form Null hypothesis Alternative hypothesis
Classes Directional Non-directional
57
NULL HYPOTHESIS also known as statistical hypothesis or zero
hypothesis. (). labelled as H0 states that there is no difference or relationship
between the groups or variables measured. statement to be rejected.
58
ALTERNATIVE HYPOTHESIS also known as the research hypothesis or working
hypothesis. labelled as Ha. states that there is a difference or relationships
between groups or variables that are being measured.
statement to be accepted.
59
DIRECTIONAL HYPOTHESIS is a hypothesis that specifies the direction of the
predicted relationship that is whether the predicted relationship will be positive or negative.
enough evidence to deduce for the direction of the expected results (IV on DV).
60
NON-DIRECTIONAL HYPOTHESIS
is a hypothesis that does not indicate the direction of the expected research results.
positive or negative results of the investigation will not be stated.
61
SOME EXAMPLESNull There is no significant
relationship between number of hours studying and test score.
Alternative There is a significant relationship between number of hours studying and test score.
Directional Students who study longer hours will get higher score on the test.
Non-directional
Number of hours studying will influence test score.

71
I. MEANING AND PURPOSE OF RESEARCH DESIGN
72
What is Research Design?
A plan, structure and strategy of investigation to obtain answers to research questions or problems
It includes an outline of what the investigator will do from writing the hypotheses and their operational implications to the final analysis of data
(Kerlinger, 1986:279).
73
Purpose of Research Design
identify the most appropriate method in conducting research
identify research variable & how to operationalize it
the robust and objective research
Answer questions and make decision related to aspects such as research purpose, information/data resources, location & appropriate time to conduct the research
identify the most economical method in conducting the research

HISTORICAL RESEARCH/HISTORGRAPHY
What? Attempt to identify: Source of Data
Limitations
Study past events
i). Factors from the past that have impact on the present of the future.
ii).Factors from two or more periods in the past that may be compared and may or may not be related to the present or the future.
iii).Factors from one or more periods in the past that are compared with or related to the future.
•Documents•Oral histories•Remains, remnant, and relics

78
DESCRIPTIVE RESEARCHWhat? Case Study Survey
Describe the current state of affairs of some phenomenon at the time of the study.
Study an individual or an institution as detailed as possible.
Basic tools:Indepth interviewQualitative observation
Study directly the characteristics of population thro’ surveys.
Examines the frequency & relationships betw. psychological and sociological variables --- attitudes, beliefs, prejudice, opinion.
Basic tools:QuestionnaireInterviews
79

breadthiv. not for establishing
any cause- and-effect links
v. generalizability is limited
Biasi. Interviewer biasii. Questionnaire bias
Uncooperative respondents
iii.Refused to answer as in mail surveys
80
Developmental ResearchStudy patterns and sequences of growth and/or change as part or function of time.
Longitudinal Research Cross-Sectional Research
• Examines one group of people repeatedly over time,
• Examine change over an extended period of time.
• Study same respondents studied according to age increment
• Examines several groups of people at one point in time.
• Examine age differences rather than age changes.
• Study different respondents with different age categories.
81
ADVANTAGES
Longitudinal Research Cross-Sectional Research
Reveals extensive detail on the process of of development
Inexpensive
High comparability of (the same) groups
Short time span
Allows for the study of continuity between widely differing groups
Low dropout rate
Allows modified cause and effect speculation about the relationship between variables
Requires no long-term administration or cooperation between staff and participants
82
DISADVANTAGESLongitudinal Research Cross-Sectional Research
Expensive to conduct Limits comparability of groups
Potential for high dropout rate (mortality/attrition)
Gives no idea as to the direction of change that a group might take.
Examines people of the different chronological age
Examines people of the same chronological age who may be of different maturational ages.
Reveals continuity of development on a person-by-person case.
Reveals nothing about the continuity of development on a person-by-person case.
83
Correlational Research
Describes the linear relationship between 2 or more variables
no hinting on the effect of one variable to another
Determine the extent to which variations/change in one factor/variable,
Corresponds/relates to variations in one or > other factors/variables.
84
Focus on the amount of variance shared between 2 variables.
That is the more 2 things have in common, the more strongly related they will be to each other
(e.g., relationship between reading & mathematics vs. reading & physical strength.
A
B

3
Frequent measure used to assess degree of relatedness is the correlation coefficient
a numerical index reflecting the relationship between 2 variables.
expressed as a number between -1.00 and +1.00
Strength increases as amount of variance one variable shares with another increases.
85
The important quality of a correlation coefficient is not its sign, but its absolute value.
A correlation of -.75 is stronger than a correlation of +.65, just as a correlation of +.58 is weaker than a correlation of -.70.
Pearson product moment correlation – search detail.
86
Correlations can be direct/positive as one variable changes in value, the other changes in the
same direction.
Correlations can also be indirect/negative as one variable changes in value in one direction, the other
changes in the opposite direction.
87
88
B . EXPERIMENTAL RESEARCH
Focuses on analyzing the cause and effects of a phenomenon.
To test the presence of a distinct cause and effect:
A does cause B to happen?A does not cause B to happen?(change in one factor are causally related to
changes in the other – there are not just related; i.e., they share something, but one directly affects the other)
89
True Experimental Research Design
Expt. design delineates several procedures that must be followed by researchers, as follows:
1. Determines control group randomly which, based on statistical characteristics is similar to the experimental or treatment group
(similar in statistic characteristics of the population used so that the subjects of the study are comparable and not extreme, for example, heights not exceeding 7 feet, between the two groups).
2. Control and experimental groups originate from the same population (this will help to determine similarities in terms of statistics)
90
3. Subjects in the control group are not exposed to the treatment, intervention or changes or variable(s) that will be manipulated.
4. Both groups must comprise equal numbers of subjects.
5. Conduct pre-test for the dependent variable for both control and experimental groups.
91
6. Conduct post-test for the dependent variable for both control and experimental groups.
7. Your study is complete after the post-test. You can conduct the post-test as many times as needed even when the experiment is taking place. Your research results are interpreted based on the differences in the post-tests between the experimental and control groups.
92
QUASI EXPERIMENT
is designed to parallel true experiment. not lower in value than true experiment. sometimes better and more realistic than the true
experiment.
93
sometimes known as expo-facto research since, done after phenomena took place.
IV is difficult to manipulate as in the true experiment. does not emphasize the element of randomness as in
the true experiment.
94
subject is not randomly selected to be in any kind of situation.
subjects are chosen based on the IV ( e.g., age & sex).
the validity for the quasi experimental research is lower than the true experimental research.
95
Quasi experimental research can be classified according to three categories:
1) Quasi experiment using ‘subject variables’ Comparison between different subjects Pre-test and post-test measurements of the dependent variables
2) Quasi experiment using ‘environmental variable’ (time –series design) Comparison among the same subjects Several observations made on the same subject for a period of time
3) Quasi experiment involving time panel/cohort: Testing for developmental change. For example, comparing the
academic achievement of PJJ students cohort of May 2003/04 with those of May 2005/6
96
E.G., QUASI-EXPERIMENTAL RESEARCH1). The Effects of Taking Breakfast
Experimental Group?Control Group?
2) The Effects of Cigarette Smoking on Unborn ChildExperimental Group?Control Group?
