Necessary steps for a basic research process:

Step #1:Analyze the kind of information you will be needing for your assignment.

• What type of assignment is it?• How much information do you need to complete your

assignment?• How current or up to date is your topic and the

information you need?

Necessary steps for a basic research process:

Step #2:Start looking for your information.

Gather references, books, articles, papers, and formulate your own thoughts, conclusions, and ideas.

Necessary steps for a basic research process:

Step #3:Understand your topic through reference materials. Reference collections usually contain:

•Dictionaries: general language dictionaries and subject dictionaries.

•Encyclopedias: general encyclopedias and subject encyclopedias.

•Handbooks and manuals: for practitioners within a specific discipline.

•Yearbooks: annual publications.•Directories: lists arranged in alphabetical or subject order.

•Atlases.•Biographical reference sources.

Necessary steps for a basic research process:

Step #4:Use electronic resources.

•The library catalogue or online public access catalogue (OPAC)

•Indexes to journal articles.•The Internet.

Principles of searching electronic resources

•Establish keywords: state the topic in your own words, look for synonyms and broader and narrower terms. E.g. Synonyms: sports, games, physical education Broader terms: recreation Narrower terms: soccer, motor sport…

•Use and understand Boolean operators: AND: narrows OR: broadens NOT: excludes terms.

•Combine keywords.

Formulating a search statement

AND AND

OR

Effect War Sudan

Aftermath battle The republic of the Sudan

Consequence

If we are looking for material on the “effect of war in Sudan.”

[effect OR aftermath OR consequence] AND [war OR battle] AND [Sudan OR the republic of the Sudan]

The online public access catalogue (OPAC)

An electronic database of all materials contained in the library.

A typical catalogue record could contain:•Main author•Title•Imprint•Notes•Subject•Other author.To evaluate a resource, look at:•Title and subtitle (the aspect of subject covered and the

approach to the subject)•Preface•Table of contents and index.

Research Methods – Bazara Barry

Electronic databases of journal articles

•Journal articles are essential in academic study because they are the vehicles through which current research, the latest findings and new discoveries are presented in the academic community.

•Some companies produce databases precisely for the purpose of helping people locate journal articles (INSPEC)

•Different databases produce different levels of results (citation, abstract, full text).

The World Wide Web and the Internet

•The Internet is a worldwide network of computer networks linking computers that use the TCP/IP protocols.

•The WWW is the totality of many web pages tat reside on computers all over the world.

Evaluating information found on the WWW

•Any one with the know-how and publishing access rights to an ISP’s database can publish pages on the web.

•With the vast amount of info on the WWW it is important to discern the useful from the useless.

•Not all info on the WWW is not authoritative. Many print journals and scholarly organizations allow complete or partial access to their articles.

Research Methods – Bazara Barry

Evaluating information found on the WWW

•The evaluation criteria applied to the WWW are similar to other media (accuracy, authority, objectivity, creativity, currency, and scope).

•Try answering questions such as:Who is the author, his/her organization, does he/she speak on behalf of an organization.What is the type of URL (.com, .edu, …)What kind of a site is it (advocacy, business, informational, news, personal, …)Is there evidence of bias?What is the date of publishing?Are there extravagant statements?Are there ulterior motives?
