Online teaching is beneficial for remote users, allowing them to learn at their own speed and the time and place of their choosing. However, data are lacking on whether cyberspace is an appropriate place to learn database searching.  
Purpose: To investigate the differences between teaching searching skills via web-based tutorial and traditional lecture.
Subjects: First year medical students at the University of Michigan Medical School. 
Methodology: A  Randomized 174 medical students into four groups, two receiving traditional lecture instruction in the use of Medline and two performing self-study on a tutorial. Each lecture lasted 25 minutes with tutorial groups being given an equal amount of time. The same question was presented to each group, with the resultant search strategy to be e-mailed to the medical library.  Ten minutes were allowed for the search formulation. Searches were scored by two examiners based on 10 criteria, with  0.5 to 2 points being deducted for each error%2C the highest score being a 5.
Results: We found no significant difference in test scores between the lecture groups (2.73 and 3.94) and the tutorial groups (3.87 and 4.08).  The errors across all the groups were similar: failure to use MeSH terms and to set limits properly. 
 Conclusions: We found no differences between lecture and tutorial methods. Consequently, we suggest that the benefits realized by online teaching are equal to those of traditional lecturing.  However, we identified similar problems associated with both methods: specifically, that test subjects in both groups often failed to make proper use of MeSH terms and were confused about how to limit searches.
