RESEARCH METHODOLOGY

 

by V K Vaidyan

 

 

Benefits of research

 

Ø     A critical/ scientific attitude is developed

Ø     Chance to study a subject in depth

Ø     Learning to assess the scientific literature critically

Ø     Developments of special interests and skills

Ø     Obtaining a higher degree

 

 

Classification of discoveries

 

 

Ø     By blind luck, which can provide an opportunity to any one motivated to do research. [e.g., unexpected arrival of a patient with rare decease]

Ø     Luck and action [e.g., Mössbauer effect]

Ø     Chance presents a faint clue, but it will be overlooked except by that one person equipped to grasp its significance. [e.g., Alexander Fleming discovered penicillin by serendipity in 1929, but only in 1939 Florey and Chain working at Oxford revealed its practical importance.]

Ø     To intercept the problem at an odd angle. [e.g., Matter waves, Special theory of relativity]

 

 

Types of discoveries

 

Ø     Basic research – fundamental to most of the major advances made [e.g., theory of electromagnetic (EM) induction]

Ø     Applied research [e.g., theory of EM induction applied to design a dynamo]

Ø     Developmental [e.g., development of electric generator]

 

 

Planning research

 

Research starts with an idea. Then, we ask the following questions:

Ø     Is the idea viable?

Ø     Is it practical?

Ø     Has it been done before?

Ø      What result is expected?

Ø      What will I do?

 

 

Application for research grant

 

 

Points to be considered by the applicant:

Ø     the need

Ø     the plan

Ø     the method

Ø     the resources

 

 

Project evaluation

 

Project evaluation by experts:

Ø     Is the idea important?

Ø     Can it be done?

Ø     Is the applicant competent to do the work?

Ø     Can it be done with the specified time?

Ø     Are the costs realistic?

 

 

Reasons
for rejection

 

Ø     Scientific merit of the idea is not worth

Ø     Project planning needs improvement

Ø     More reliance on others to do the work

Ø      Too much money asked for the project

 

 

Searching literature

 

 

Journals

 

Journals are the principal vehicle of communication of scientific information and have the following advantages:

Ø     More recent information than found in books

Ø     Main channel of communication among scientists

 

 

Indexing and abstracting journals

 

Ø     Indexing journal [e.g., Current Contents] lists in a convenient way the contents of a number of journals

Ø     Abstracting journal [e.g., Physics Abstracts] performs the same function with an abstract of the papers indexed

 

 

Searching

 

Ø     Select the subject headings of interest

Ø     Find the papers/ articles of interest from the recent issue

Ø     Note the review papers in particular

Ø     Review papers together with relevant monographs give basic information

Ø     Begin with an article read in a current journal proceed to papers giving more specific information

 

 

Keeping
up to date

 

Current Contents can be used in three ways:

Ø     By looking through the author index for names of authors you know to working in your field of interest

Ø     By looking through the content page of journals of interest

Ø     By looking through the subject index

 

 

Conclusion

Ø     Literature searching is an essential primary step, though it is time consuming and laborious

Ø     In this context, computer retrieval services are particularly valuable

Ø     The purpose is to make sure that you are doing something new to carry out your planned research project and to publish the results

 

 
Speaking at meetings

 

 

William J Mayo
 (1861-1939)

 

“Begin with an arresting sentence; close with a strong summary; in between speak simply, clearly and always to the point; and above all be brief.”

 

 

Speaking
& writing

 

Ø     A speech should be looser in texture, and less detailed than an article

Ø     In listening, continuous attention is needed; there is no time pause to linger over difficult passages, or to study an illustration again

Ø     No one wants to hear a speaker “talking like a book”.

 

 

Style

 

Ø     Simple pattern – beginning, middle and end – should be followed

Ø     Three essentials for good communication are preparation, pruning, rehearsal

 

 

Warning

 

When young inexperienced research workers come to give a talk to the members of a learned society, they are warned:

‘Remember you are addressing a most distinguished assembly of scientists. Therefore, you should speak to them as though they are children of four years age’.

 

 

Sustaining interest

 

Ø     Rhetoric: One can improve his diction by apt choice of words

Ø     Examples: Example aids understanding

Ø     Humour: Humour revives interest and gives relief

Ø     Setting problems: Listeners can take part in finding solutions

Ø     Provocation: Audience may be provoked to create interest

Ø     Mentioning contemporary problems:

Ø     Allowing interruptions

Ø     Using visual aids

 

 

Illustrating talks

 

‘One picture is worth more than ten thousand words’

-Ancient Chinese Proverb

 

 

Slide content

 

Ø     Text

Ø     Data as tables, charts or as diagrams

Ø     Drawings

Ø     Picture

 

 

Data

 

Data should stimulate the interest of the audience, which can be presented as:

Ø     Tables

Ø     Bar charts (to illustrate comparison)

Ø     Pie charts (to illustrate division into parts)

Ø     Line graphs

Ø     Scatter diagrams

Ø     Flow charts (to show successive stages)

 

Pictures

 

Ø     Pictures must be clear and not overcrowded with information

Ø     An amusing or illustrated picture can also be inserted

 

 

Preparation

 

Ø     Write the script

Ø     Define the content of each slide

Ø     Prepare the slide

Ø     Construct graphics, tables, figures

Ø     Photograph/ scan the art work

Ø     Do the rehearsals

 

 

Writing original paper

 

 

Assessment

 

Ø     What is the message?

Ø     Why is the paper worth writing?

Ø     Who will read the paper?

Ø     Who will the authors be?

Ø     Which journal?

 

 

Manuscript preparation

 

Before writing the article, the author should have an idea to whom he is writing:

Ø     to a small group of fellow experts

Ø     to a wider scientific community

Ø     Journal’s instructions to authors should be read before writing the paper

 

 

Article structure

 

Ø     Title is what catches the readers’ eye and deserves careful thought

Ø     Introduction – Why did you start?

Ø     Methods – What did you do?

Ø     Results – What did you find?

Ø     Discussion – What do the results mean?

Ø     References – provided to indicate the sources from which you have obtained information.

 

 

Abstract

 

Ø     It must contain the essence of introduction, the methods, the main findings and main conclusions

Ø     The style can be impersonal and condensed

Ø     It should not contain material that is not in the article

 

 

Reasons for rejection

 

Ø     Logic or validity of results doubtful

Ø     The matter is not original

Ø     Unsuitable for the journal

Ø     The article is too long for information that it contains

Ø     The article is written badly

 

 

Editing

 

 

Ø     Journals will check grammar, spelling and punctuation, lay out of tables and figures, and check the paper for internal consistency

Ø     Check for units of measurements, which should be in SI

Ø     Check for references and nomenclature
