Comepetency 6: Search 2 Specific Facet First in Libray Literature and Information Science

Specific Facet First Strategy

database: Library Literature and Information Science database

Query: I am a first year elementary school librarian and I would like to learn how to teach elementary school students how to research information. What resources can I use that would help me teach research skills in an elementary school library?

Facets from query
facet 1: teach
facet 2: research skills
facet 3: elementary school library

Synonyms for facets
facet 1: teaching, instruction, lessons
facet 2: information literacy, library skills
facet 3: school library media center

subject terms
facet 1: bibliographic instruction/elementary and high school students, school libraries/activity projects,
facet 2: research techniques/teaching
facet 3: school libraries/elementary schools

subject search records results
bibliographic instruction/elementary and high school students -
1294 records
school libraries/activity projects - 2358 records
research techniques/teaching - 239 records
school libraries/elementary schools - 35 records

research techniques/teaching and school libraries/elementary schools have the smallest retrieval sets, so I combined them first.

search statement 1
su=(research techniques/teaching) AND (school libraries/elementary school)
results: zero records

search statement 2
su=(research techniques/teaching) AND (bibliographic instruction/elementary and high school students)
results: 49 records

WOW! This is a good retrieval set. There were many records that fit the query.

Reflection:
I liked using this strategy. It let me know how many records for each facet alone and I can combine the most specific facets first to see what kind of retrieval sets it come up with. Once I had the best subject terms possible for all the initial facets and synonyms, the retrieval set was so much better.

I tried the following search statement and the retrieval set consisted of only 6 records of which only 1 was relevant to the query.

search statement 3
su=(research techniques/teaching) AND (school libraries/activity projects)

I also tried a building block strategy using all the subject terms just to see what kind of retrieval set I would get.

search statement 4
su=(bibliographic instruction/elementary and high school students OR school library/activity projects) AND (research techniques/teaching) AND (school libraries/elementary schools)
results: zero results

I can see how this strategy is useful if an initial Boolean statement using the building block strategy has zero results.
