Known article from previous searches: Implications of an experimental information technology curriculum for elementary students
Default settings employed.
Ching, Gregory
Search au= Ching
ti= technology curriculum
Searched title,author and 1st subject heading "educational technology" with 3,448,523 results.
To expand the recall or "snowball" the results, it is necessary to return to original document and choose subsequent subject headings.
Because the purpose of Citation Pearl Growing is to expand the results, with over three million hits using the original title and the first subject heading, additional searches were deemed unnecessary.
The large amount of results in the first attempt was a surprise and made me wonder if the strategy was necessary for this query.
