What is
ERIC on CD-ROM?
ERIC (Educational Resources Information Center) is a CD-ROM database
that provides access to the literature in the field of education
.From the database one can retrieve bibliographic citations , with
abstracts , to CIJE (Current Index to Journals in education ) journal
articles and RIE ( Resources in Education ) documents.
About
the ERIC Network
ERIC is the National Education Information Network for providing
access to the literature in education and related fields.The nationwide
ERIC network consists of 16 clearinghouses and 9 adjuct clearinghouses
. The clearinghouses are located at universities and profesional
organisations . Each clearinghouses specializes in a different multidisciplinary
educational area , and gathers the pertinent journal articles and
documents of their respective subject areas. ERIC screens the articles
according to the ERIC selection criteria , then abstracts and indexes
the selected materials. ERIC is sponsored by the U.S. Department
of Education.
Coverage

The Journal
Article : Where Learning Begins
ERIC on CD- ROM is the only a tool that tells one what journals
contain articles on one's subject of interest. Once relevant citations
are retrived check to see if the library subscribes to the journal
.If the library subscribes to the journal fill out a periodical
call slip and hand it in at the Periodicals Desk on the 4th floor
of the LLC building.If the library does not subscribe to the journal
fill out an interlibrary loan(ILL) form at the desk in the
Refence Library.The library will obtain the article from another
library and notify you when it arrives (1-2 weeks).

Fields
The
Database
The databse is where the records are contained .ERIC is one
of eleven databases available to library users.To start the
ERIC database choose "A) Education (ERIC)" from the "CD-ROM
Network Applications" menu. If the CD-ROM Network Applications
menu is not on the screen select Quit from the commands
menu or press Ctrl, Alt , and Delete simultaneously
. This will restart the computer from the main menu.
Records
The record is primarily a bibliographic citation, including
abstract, for a particular article.The record is broken down
into specific fields.
Fields
The Fields which make up the recordare the basic components
of a bilbliographic citation and other descriptive information
.The fields one will examine to evaluate the usefulness of a
record are :
AU : (author)
TI : (title)
PY : (publication year)
JN : (journal name , date , and volume number ; article page
numbers)
DE: (major descriptor /subjects)
DE: (minor descriptor /subjects)
AB: (=abstract /articles summary )
Less
important fields for the average database search are:
AN : (accession number)
CS :(corporate sponsor)
AV :(availibility)
NT :(descriptive note)
PR :(EDRS price)
ID :(identifiers)
| Searching Techniques and Retrieving Records |
Objective
When conducting a database search the objective is to retrieve
a minimum number of records which contain the desired information
in the appropiate context.The database is most useful when you
know what type of information you are looking for and are familiar
with the subject terminology.Below are searching techniques
which allow one to construct and narrow a search to avoid scrolling
through hundreds of irrelevant records.
Only basic
searching techniques are covered here.With practice and experience
more sophisticated techniques can be aquired and used when necessary.For
most non-professionals the basics are more than enough. If hundreds
of records are retrived and one cannot think of a way to narrow
the search, consult a Reference librarian.Reference Librarians
are here to teach students, faculty and staff how to retrieve
information using all of the library 's resources.
Keyword/Free
Text Searching
When terms (keywords) are entered into the computer the computer
will search for the terms through out the record, and retrieve
all of the record in which the term appears, no matter what
the context.keyword searching is the opposit of field specific
searching (see page 4)
To retrieve
records from the database, at the Find: line type in
a search term and press Enter. A search term can be a
single or several word term which describes the subject.
For Example
:
- Find
: Intelligence tests
- Find
: Wechsler intelligence scale
Boolean
Searching
Boolean Searching allows one to combine search terms using the
booloean operators "and", "or", and "not".This
way one can be as specific as possible and eliminate inappropiate
records.The computer will retrieve records in which all of the
search terms appear. For example:
-
Find:Wechsler intelligence scale and learning disabilities
-
Find:Adolescents and attention deficit and diagnostic tests
-
Find:Diagnostic tests and (behaviour problems or attention
deficit)
-
Find:Language tests and reliability not secound language
Truncation
By putting an *(asterisk) on the trunk of a partial spelling
the computer will search for the root word with its various
endings.An example of the various endings to the following truncated
terms may include disaabled, disability, disabilities, score,
scores, scoring,
Find : diagnostic tests and learning disab* and scor*
Field
Specific Searching
Field specific searching allows one to serach by a specific
field in the record. The computer will only retrieve records
in which the term appears in the feild indicated.This is a way
in which one can control the context in which the term(s) appears,
and eliminate irrelevant records.
Construct
a field specific searchby typing the command "in"
following the term and indicating what field(i.e., AU, TI, DE)
the computer should look for the term in.For example:
- Find
: measurement technique in de
- Find
: measurement techniques in de and behavioural sciences in
de
- Find
: measurememt in de and engelhard-g* in au
One can
also search by publication year.This is useful if one
is looking for an article published in a certain year, by a
particular author. One can also search a range of years. For
example :
- Find
:engelhard-g* in au and py=1994
- Find
: (measurement or assessment) in de and writing in de and engelhard-g*
in au and py=1994-1996.
| Menu
Commands and On-screen Instructions |
The
menu commands are located at the bottom of the screen. These
commands allow one to change screens and excute particular
functions(i.e.,print). READ THE SCREEN
Most databases use the natural language commands , meaning
the commands should be self explanatory and do what they say.the
most common sets of menu commands are:
| MARK
