This is an outstanding question and one that should be asked by anyone interviewing at a medical school!
I believe that all schools should do the following:
Have board style questions for exams. These should be well written and vetted by fellow faculty for content, veracity, format and historical performance. To my amazement, there are schools, like
LizzyM's that have staff that do nothing but this!
Have subject reviews at set times during the curriculum, with emphasis on explaining why the right answers are correct, and the wrong answers aren't
Have enough time prior to Boards for self study (my kids get about 3-5 weeks)
Have lecture content that is geared to both Boards and wards (yes, you need to know things for your preceptors). personally, I have no problem teaching to the Boards.
Keep state of the art, scientific findings to a minimum
Never, ever should a lecturer discuss their research as part of coursework
Encourage active learning
Reinforce concepts throughout the two years of pre-clinical study
Have exams that mimic Boards.total content. ie, Your exams should be of mixed content, not, say Anatomy on Monday, Physiology on Tuesday during exam block week. No silos for content!
Not allow students to take Boards until they ready. If you have to burn an elective for more study time, all the better.
