Each database uses controlled subject headings. When searching, combine or group terms using the Boolean operator "AND" to refine your search string: writing evaluation AND English instruction or try the search string: writing processes AND teaching methods AND secondary. Check to see if it offers a Thesaurus or a Subject Terms tab. For instance, in ERIC, choose the Thesaurus tab and in the Browsing box enter terms to see how the database recognizes them:
"writing centers" would be "laboratories; writing (composition)"
"writing development" would be "writing (composition)".
Additional subject headings include writing instruction, writing strategies
English instruction, English curriculum.
Most databases use a controlled vocabulary to organize information and make browsing more efficient and specific to chosen terms. When building your search string, consider keywords, synonyms or related terms. See several examples in the table below.
| Subject Terms | Related Terms |
|---|---|
| Writing Composition | writing processes, writing skills, writing strategies, writing instruction |
| Reading Comprehension | reading skills, critical reading, reading strategies |
| Vocabulary | lexicology, vocabulary development, vocabulary skills, word lists |
Combine or group terms or concepts using the Boolean operator "AND" to refine your search string: vocabulary AND word lists, or try the search string: writing composition AND writing processes. Check to see if the database offers a Thesaurus or a Subject Terms tab or link. For instance, the database Academic Search Premier offers a "subject terms" tab, and the ERIC database features a "thesaurus" tab. Enter terms in the Browsing box to see how the database recognizes them.
Depending on the database, it may offer a variety of ways to limit your results:
