The usual definition of RESEARCH...

“going to the library”

“google-ing some key words”

What’s your definition???

MMPBalolong


RESEARCH

the process of constant exploration and discovery

the process of discovering new information and gain new knowledge

MMPBalolong


SCIENTIFIC RESEARCHsystematic, controlled, empirical, critical investigation of hypothetical prepositions about the presumed relations among natural phenomena (Kerlinger, 1973)

MMPBalolong


SCIENTIFIC RESEARCHa process through which we attempt to achieve SYSTEMATICALLY and with the support of data:

the answer to a question

8 DISTINCT CHARACTERISTICS

OF A RESEARCH METHODOLOGY

MMPBalolongThursday, December 8, 2011

1. Originates with a question or problem

What are he environmental factors that increase shrimp productivity?

What active compound in atis leaves extract is cytotoxic to cancer cells?

MMPBalolong


2. Requires a clear articulation of a goalWhat precisely do you intend to do?

Example: to determine the difference in body weight loss after administration of various plant extracts

MMPBalolong


3. Follows a specific plan of procedure

carefully planned

methods in a purposeful way: to yield data relevant to their particular research problem

MMPBalolong


4. Usually divides the principal problem into more manageable subproblems

principal problem: How do we get from UP Manila to Trinoma?

subproblems:

What is the most direct route?

How far do I travel by train?

How much will I spend to reach my destination?

MMPBalolong


5. Guided by specific research problem, question or hypothesis

hypothesizing: attempting to account for the cause (*guesses)

MMPBalolong


6. Accepts certain critical assumptions

it is necessary to assume

MMPBalolong

7. Research requires the collection and interpretation of data in attempting to resolve the problem that initiated the research


8. It follows logical, developmental stages

From questions to answer

“research begets research”

MMPBalolong


ULTIMATE AIM OF RESEARCHTo fill in the gaps along the stream of knowledge

To provide solution to contradictory results from previous studies

To satisfy one’s curiosity and quest for knowledge

To find truths for the satisfaction of answering questions and using this new information to help others

MMPBalolong


EXPERIMENTALPurpose: the only method of research which can truly test ! ! ! ! hypothesis concerning cause-effect relationship.

the effect of a single variable applied to one situation can be assessed and the difference determined

Independent Variable : also referred to as the experimental variable, the cause, or the treatment, is that activity or characteristic believed to make a difference.

Dependent Variable : also known as the criterion variable, effect, or posttest is the outcome of the study, the change or difference in groups which occurs as a result of the manipulation of the independent variable.

Example: 1.! Effect of varying concentrations of Pb on the brain of golden apple snail

FORMULATION OF RESEARCH OBJECTIVES

RESEARCH OBJECTIVES

REFLECT THE QUESTIONS WHOSE ANSWERS THE INVESTIGATOR WANTS TO STUDY YIELD TO

CAN BE EXPRESSED EITHER IN THE FORM OF A STATEMENT OR A QUESTION

SERVES AS THE STEERING WHEEL IN THE CONDUCT OF A RESEARCH PROJECT

SERVES A S AGUIDE IN SPECIFYING VARIABLES TILL INTERPRETATION OF RESULTS

General Objective: to identify the reasons for this low utilization

HOW DO YOU FORMULATE YOUR OBJECTIVES?

MMPBalolong


SPECIFIC

smaller, logically connected parts of a general objective

should systematically address the various aspects (dimensions) of the general objective

should specify what you will do in your study, where and for what purpose.!

HOW DO YOU FORMULATE YOUR OBJECTIVES?

MMPBalolong


Clearly phrased in operational terms

Use action verbs

Examples: explain, apply, predict, identify, employ, evaluate, describe, illustrate, defend, integrate, use, assess, contrast, interpret, distinguish, sort, categorize, diagram, solve, formulate, report, relate, organize, restate, recall, prepare, review, list, arrange, classify, name, construct, translate, recognize, create, determine

GENERAL: To evaluate if home-based care (CHBC) projects in Zimbabwe provide adequate, affordable and sustainable care of good quality to people with HIV/AIDS, and to identify ways in which these services can be improved

SPECIFIC

To identify the full range of economic, psychosocial, health/nursing care and other needs of patients and their families affected by AIDS.

To determine the extent to which formal and informal support systems address these needs from the viewpoint of service providers as well as patients.

To determine the economic costs of CHBC to the patient and family as well as to the formal CHBC programmes themselves.

To relate the calculated costs to the quality of care provided to the patient by the family and to the family/patient by the CHBC programme.

FACTORS TO CONSIDER


THE LITERATURE REVIEW

Evaluating Others’ and Developing Your Own


After the research problem has been identified and the objectives formulated, a review of related literature needs to be done.

Two Important Uses:

• To get acquainted with the existing studies related to the research to be conducted relative to:

- who have done the work on the problem area- what has been found- research design utilized- statistical analysis applied- problem met and how were they resolved

• To establish a rationale or a theoretical or conceptual framework based on previous research studies done.

REVIEW OF RELATED LITERATURE


RELATED LITERATURE: Composed of discussions of facts and principles to which the present study is related

RELATED STUDIES: studies, inquiries or investigations conducted to which the present proposed study is related or has some bearing or similarity

usually unpublished materials

manuscripts; theses; dissertations



It identifies the start for the research problem by presenting the gaps, weak points, and inconsistencies in the previous researches. This provides the study with a conceptual framework justifying the need for investigations.

It puts together all the constructs or concepts that are related with the researcher’s topic. The theory then leads you into the specific questions to ask in your own investigation

It presents the relationships among variables that have been investigated. This process enables you to view your topic on hand against the findings earlier bared.

FUNCTIONS OF YOUR RRL


The surveyed materials must be as recent as possibleMaterials reviewed must be objective and unbiasedMaterials surveyed must be relevant to the study

Surveyed materials must have been based upon genuinely original and true facts or data to make them valid and reliable

Reviewed materials must not be too few or too many

CHARACTERISTICS OF YOUR RRL


HOW TO CONDUCT THE REVIEW OF RELATED

LITERATURE“WHERE DO I GO FROM HERE?”


personal or school library (magazines, journals, books, etc)

attend seminars, scientific meetings (under your topic of course)...take down notes

do a computer-aided search through databases

example: www.scirus.com; pubmed; SCIENCE DIRECT, etc

WHERE TO SEARCH


http://www.scirus.com

http://www.scirus.com

You can actually ask for reprints:

via postcards

via request letters

via emails

WHERE ELSE???


AFTER ALL THESE PHOTOX WHAT’S NEXT?

Results to Compare with My Results

Pros and Cons of Controversy

Others...it may be of use (malay mo!)

ORGANIZING YOUR RRL


write all bibliographic information, i.e., author(s), complete title, publisher, date and place of publication, and so on

write what others have said on the subject plus your own impressions and comments

ALSO....


IT’S TIME TO WRITE...AVOIDING PLAGIARISM!


Use headings arranged in logical order to indicate main points

Avoid too long introduction to your main topic.

Include information that are directly related and relevant to your topic.

A maximum of half-page (double-space) must constitute one paragraph

Do not copy in toto the information from your source. No more than 10% of the entire paper is allowed for direct quotation



Give due credit to the real source of your data. Cite the authors at the end of the sentence.

Paraphrase using your own words and style the data gathered.

Summarize important points from your sources and relate them to your topic.

Reinforce your data with selected figures or statistics from your course.



A common problem...

“turning your list of ideas into a BORING review”


Make subheads (not too many), transitional phrases and unifying ideas to make information flow smoothly

HOW TO AVOID IT


Spice your writing with a variety. Keep your paper alive!

Vary the way sentence and paragraph begins:

Author A found out

Author B found out

Replace found out with:

demonstrates; presented evidence for; supported; observed; reported; examined; concluded

Early in the 1980’s, author A

According to Author A,



READY TO DO YOUR RRL?


But before that, let us learn to critique or evaluate a research

study


Why did the Researchers do this particular study?

Who/What was/were studied?

How was the study done?

What did the researchers find?

What were the limitations of the study?

What are the implications of the study?
