Background. There has been little systematic attention to the opinions
of faculty in evaluating problem-based learning (PBL). The purpose of
this report is to describe the attitudes and opinions of tutors in PB
L programs about the relative merits of PBL and traditional medical ed
ucation, and to examine the influences of selected variables on these
attitudes. Method. Questionnaires containing both Likert-type and open
-ended questions were sent to 1,287 faculty members who had served as
PBL tutors at 22 U.S. and Canadian medical schools during the 1992-93
academic year. All schools with identifiable PBL programs (broadly def
ined) were included in the survey. Results. The overall response rate
was 69% (882 of 1,287). As a group, the respondents were experienced i
n both PBL and traditional curricula, with an average of 3.75 years of
experience in the former and 11.41 years of experience in the latter.
Regarding both their overall attitudes and their opinions about seven
of nine specific areas, the respondents evaluated PBL more positively
than traditional methods. This was especially evident in the ratings
of student interest and enthusiasm, faculty interest and enthusiasm, t
he respondents' personal satisfaction, student reasoning, and preparat
ion for clinical rotations. The two methods were judged to be approxim
ately equally efficient for learning. Traditional methods were judged
to be superior for teaching factual knowledge of basic sciences. PBL w
as particularly popular with faculty in PBL-track programs, with facul
ty in both the newest and the oldest PBL programs, and with faculty in
either primary care or ''nontraditional'' specialties. Conclusion. Th
e findings confirm and extend the picture of PBL strengths and weaknes
ses that can be derived from prior anecdotal program descriptions and
small sample studies. Experienced faculty seem to prefer PBL in most r
espects, although they have some serious reservations. The present fin
dings also agree with prior outcome studies of PBL, suggesting that th
e most strongly held faculty opinions may have a factual basis.
