Difference betweenProblem Based Learning(PBL) and Case Based Learning (CBL) By: Dr. Izza Umbrin

LEARNING OBJECTIVES:

Understand Case Based Learning CBL Understand Problem Based Learning PBL Elaborate differences between CBL and PBL

Academic Medicine, Vol. 82, No. 1 / January 2007 Comparing Problem-Based Learning withCase-Based Learning: Effects of a MajorCurricular Shift at Two Institutions

Shift of PBL to CBL in The University of California, Davis, School of Medicine (UCD) and the University of California, Los Angeles, David Geffen School of Medicine at UCLA (UCLA)

10 months research and then shifted to other model, over 2 to 3 years

Learners had at least 1 year experience with PBL

286/348 students responded

31 faculty members responded

Each group had 7 to 9 learners, and 2 faculty members; a clinical faculty and a mental health faculty

Faculty was trained for both PBL and CBL

2-3 hours session,15 to 25 total sessions. (30 mins for SP)

24-item questionnaire

Background Of Problem Based Learning (PBL)

Problem(clinical case)

Explore case(brain storming)

Self directed learning

Group discussion & conclusion

Facilitator’sRole

IsPASSIVE

Background of Case Based Learning (CBL)

Prior reading

Problem (clinical cases, SP, video tapes)

Seek outside sources of information and Case discussion

Learners interview SP with time-outs

Facilitator’s role

IsACTIVE

Differences between CBL & PBL

CBL PBLMethod Guided inquiry Open inquiryPre reading material Provided Not providedFaculty advance preparation

yes Yes

Role of facilitator ActiveUses guiding questionsModerate loud learnersProvide feedback

Passive Don't guide discussion even when learner explore tangents

Interaction with faculty less more

Skills learned clinical Problem solving

Differences between CBL & PBL

CBL PBLPost session work Less More (include work

without benefit)

Learning curiosity No yes

conclusion Correct May be false

Self directed learning Less More ( may not be relevant)

Listening skills less more

Results:

No advantage of CBL:5% students and faculty

No advantage of PBL:23% students 3% faculty

In favor of CBL:UCLA: 90% students78% faculty

UCD:85% students100% faculty

Conclusion

CBL was preferred because it is structured approach. it keeps the learning relevant (by providing pre reading material) and enhances clinical skills. There’s less busy work. Facilitators participate actively and lead learners towards learning objectives .

Advantages of PBL identified majorly by faculty are that it enhances problem solving and self-directed learning

Which method produces better physicians?????
