Concepts and Research Problems
PROBLEMResearch study begins with human’s curiosity about the world.Problem is what people want to know about in this world
Approaches to obtain answer
NON SCIENTIFIC SCIENTIFIC
Common sense, prejudice, intuition, trial and erros, etc
With the power of reason and logic, take coherent and controlled procedures, base their methods on real evidence
Research Problem is……Research problem is the problem that preceding the research and causing the research itself. It is caused by the people’s curiosity or something that they want to know about. Then, the people try to obtain the answer of the problem through the scientific method.
Research Purposes Aim: to find an answer to a problem
through scientific procedures
From the way results are used, research can be classified into
THEORETICAL RESEARCH
(basic research)
PRACTICAL RESEARCH
(applied research)
Is needed to provide bases for solving the problems encountered in actual human life
Is needed to solve actual problems

CHARACTERISTIC OF A RESEARCH PROBLEMA problem statement must have the following characteristics:
it should ask about a relationship between two or more variables.
It should be stated clearly and unambiguously usually in question form.
it should be testable by empirical methods, that is, it should be possible to collect data to answer the questions asked.
it should not represent a moral or ethical position.
Relationship between Variables In this kind of problem the researcher
manipulates a minimum of one variable to determine its effect on other variables.
A problem statement will require at least two variables and their relation.
For example:Are boys more likely than girls to have IQ’s in excess of 120?
The Problem is Stated in Question Form What is relationship between IQ and
achievement? Is there a relationship between racial
background and dropout rate? What is the relationship between rote
learning ability and socio-economics status?
See on page 74-75
Empirical Testability A problem should be testable by
empirical methods, that is through the collection of data.
Avoidance of Moral or Ethical Judgments Questions about ideals or values are often
more difficult to study than questions about attitudes or performance.
For example:Are all philosophies equally inspiring?Should students avoid cheating under all circumstances? These example represent moral and
ethical issues and should be avoided.
Specific Considerations in Choosing a Problem1. Workability it refers problem’s
performnce 2. Critical Mass 3. Interest4. Theoretical Value references 5. Practical Value
RESEARCH PREPARATION
1. Identification of Research ProblemsProblem arise when there are gaps between expectations (Das sollen) and reality (Das sein).It takes a few steps to be able to identify research problem:1. Observe a phenomenon or phenomena.2. Take references.3. Compare the phenomena with your references.4. Determine whether or not there are gaps between
the phenomena and your references.5. Formulate the problems based on the perceived
gaps.
2. Selecting a Research Problem Nunan (1992) calls the problem as one of three
principal components of the study. Two other components are the data and the analysis.
Tuckman (1978) states among these requirements are that research problem should be:
1. About relationships between two or more variables.
2. Specific in the sense it refers to something particular, not being too broad nor too narrow.
3. Answerable by using empirical methods.4. Exempted from ethical or moral values.
3. Conceptualization and formulation of the research problem
The process of transforming reality into concept is called conceptualization. It is done by extracting the meaning that is shared by collection of phenomena.4. Identification and operational definition of variable5. Formulating of hypotheses6. Constructing research design 7. Constructing research instruments8. Sampling techniques
FORMULATING HYPOTHESES
Hypothesis is… Hypothesis is an expectation about
events based on generalizations of the assumed relationship between variables.
It also can be shorten that hypothesis is a temporary answer to the research problem.
Hypothesis Shapes and guides a research study in terms of:
identification of study sample size what issues should be involved in data
collection the proper analysis of the data data interpretation
Characteristics of hypothesis It is about a relationship between two or
more variables It should be stated clearly and
unambiguously in the form of a declarative sentence
It should be testable, then can be evaluated based on the data
Specific Hypothesis and General Hypothesis Specific hypotheses: they require
fewer observations for testing,
General hypotheses: after being observed, they will be formulated to a more specific one
The process to draw upon in developing hypothesis Deduction
Induction
Deduction-- General to Specific
In deductive reasoning, thinking proceeds from general assumption to specific application
GENERAL SPECIFIC
Induction Specific to General Conclusions about events (general) are
based on information generated through many individual and direct observations (specific).
SPECIFIC GENERAL Researchers observe an individual or group
of individuals from a larger population based on these observations, generalizations are made back to the larger population.
Alternative hypothesis is the hypothesis that affirmed. We construct them if the null hypothesis is rejected.
A null hypothesis is: the general statement that states there is no relationship between two measured phenomena. The advantage of using it in research is because in the reality it is difficult to obtain unequivocal support for a hypothesis so that the researcher attempts to test and disprove its negation.
