UCSF has a curriculum that is largely a 'hybrid' of small group, problem based learning, and lecture. I really like it a lot so far. The lectures are mainly to give background information about what we focus on in the labs (anatomy, histology, radiology). We also meet up to do 'surface anatomy', where we take our shirts off and draw on each other with erasable markers (girls where sports bras, bathing suits, etc). It is actually really helpful.
We have been breaking up into groups of 10 or so (this is our small group) and interactively reviewing the basic principles of pharmacology and cell biology about every other week.
We have one PBL case per block (about two per quarter) where we go over a case and develop a problem list and a learning list, which gets divided amongst the pbl group (which is a different group than the small group). We then go research the answers to our questions and post them online (we have a pretty amazing online curriculum/forum/self-assessments/etc).
We also belong to another smaller group for a course called foundations of patient care. Six of us, along with a preceptor, go into the hospitals (once a week) and interview a patient. For example, next week me and another classmate have to interview a cardiovascular patient about the chief complaint, past medical history, health related behaviors, family medical history, etc..They have us interviewing patients one week into school.
We have ANOTHER small group that meets starting in October where we practice physical examinations on one another.
All in all, we have about two hours of lecture per day, along with two hours of either lab, small group, or pbl. Then, once a week we have the clinical course as well (2 hours in the afternoon).
All of the subject material is presented to us in block systems. For instance, we have prologue now, then a cardiovascualar block to finish the quarter. Then, after new year's we have pulmonary, renal, cancer, and brain mind and behavior to finish our the first year. I think it is pretty sweet to learn about both the basic science and pathology of organ systems. Having things integrated like that leads to less redundancy and is a lot more efficient.
