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

Page 5: Research problem group 2

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

Page 6: Research problem group 2

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.

Page 7: Research problem group 2

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.

Page 11: Research problem group 2

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?

Page 12: Research problem group 2

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

Page 13: Research problem group 2

Empirical Testability A problem should be testable by

empirical methods, that is through the collection of data.

Page 14: Research problem group 2

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.

RESEARCH PREPARATION

Page 17: Research problem group 2

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.

Page 18: Research problem group 2

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.

Page 19: Research problem group 2

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

Page 20: Research problem group 2

FORMULATING HYPOTHESES

Page 21: Research problem group 2

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.

Page 22: Research problem group 2

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

Page 23: Research problem group 2

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

Page 24: Research problem group 2

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

Page 25: Research problem group 2

The process to draw upon in developing hypothesis Deduction

Induction

Page 26: Research problem group 2

Deduction-- General to Specific

In deductive reasoning, thinking proceeds from general assumption to specific application

GENERAL SPECIFIC

Page 27: Research problem group 2

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.

Page 28: Research problem group 2

Alternative hypothesis is the hypothesis that affirmed. We construct them if the null hypothesis is rejected.

Page 29: Research problem group 2

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.
