Results Perceived competence higher than demonstrated competence Initial perception of the level of their searching skills was greater than performance of those skills for the sample search. The pre -survey perceptions = post -intervention observed performance PBL is effective The intervention was effective in raising: self-reported knowledge demonstrated skills Students and librarians like PBL
However... After the intervention... Students believed that their searching skills had improved to a far greater extent than what was actually demonstrated in the second search attempt post-intervention.
Student Feedback Most useful: Searching on own with final review session Real-life scenario Repetition of skills required by time- released case Least useful: Lack of initial instruction Busywork Nothingall was useful
Conclusions Students have limited ability to judge their own MEDLINE skills Problem-based learning raises both perceived and actual searching skill levels.
Conclusions Librarians should continue to instruct students in MEDLINE and to refine their teaching to help close the gap between perceived and actual skills.
