- Abstract
- In order to determine whether medical students can recognize when an information need has been fulfilled and when it has not, this study examined the quality of medical students' confidence estimate in answering short-answer questions dealing with bacteriology, based upon their personal knowledge alone and what they were able to retrieve from a factual database in microbiology

- Abstract
- A search tactic is a set of search moves that are temporally and semantically related. The current study examined the tactics of medical students searching a factual database in microbiology. The students answered problems and searched the database an three occasions over a 9-month period. Their search moves were analyzed in terms of the changes in search terms used from one cycle to the next, using two different analysis methods. Common patterns were found in the students' search tactics; the most common approach was the specification of a concept, followed by the addition of one or more concepts, gradually narrowing the retrieved set before it was displayed. It was also found that the search tactics changed over time as the students' domain knowledge changed. These results have important implications for designers in developing systems that will support users' preferred ways of formulating searches. In addition, the research methods used (the coding scheme and the two data analysis methods-zero-order state transition matrices and maximal repeating patterns [MRP] analysis) are discussed in terms of their validity in future studies of search tactics.

- Abstract
- The traditional measures of online searching proficiency (recall and precision) are less appropriate when applied to the searching of full text databases. The pilot study investigated and evaluated 5 measures of overall success in searching a full text data bank. Data was drawn from INQUIRER searches conducted by medical students at North Carolina Univ. at Chapel Hill. INQUIRER ia an online database of facts and concepts in microbiology. The 5 measures were: success/failure; precision; search term overlap; number of search cycles; and time per search. Concludes that the last 4 measures look promising for the evaluation of fact data bases such as ENQUIRER

- Abstract
- The transaction logs of 53 medical students' searches of a factual database, INQUIRER, of microbiology facts and concepts were analysed in detail to determine: the overall frequency of search moves; the interaction between the problem statement and the students' search strategies; the search moves selected by individual students; and the tactics (combinations of moves) used by the students. Over 200 searches were conducted in response to clinical scenarios in microbiology and the searches were made up of 853 search moves. Results indicate that students used only a few distinct moves and that their selection of moves varied by individual and by search stimulus. Patterns also emerged in students' combinations of search moves into search tactics
