62. Selecting a good database
- Task Predict where expert information may be
found. - Search engines differ! juried (librarians
index, archive) vs. unjuried (google, ask, yahoo) - No search engine performs a live Internet search
when you submit a query ex page not found

- 90 search with Google more than half of the
time. - 32 use Google exclusively.
73. Recognizing relevant information
- (Failure occurs when a student looks at the
results returned by a search engine.) - Task Match findings with expectations, evaluate
relevance - Computers are made for speed - encourages haste
(click happy) - Hyperlinks and graphics can be distracting.
- Read snippets

84. Finding better keywords
- Task Select and try increasingly specific
keywords - Frequently, effective keywords go unnoticed in
snippets. - Effective searching depends on keyword selection
more than any other factor!

95. Evaluating credibility
- Task Check the credibility of information,
authorship - Typically, students forego this decision
altogether and accept whatever information they
find. - Special operators make evaluation easier. -
