Core problems reported by students in a palm OS and Internet-based problem entry system predicts performance on the third-year internal medicine clerkship.

CWeblog is a web and palm OS-based system used by medical students to record the problems and diagnoses of patients encountered in third-year clerkships at the Uniformed Services University. Data is available for analysis by clerkship directors as soon as it is entered. A pretest is given on the first day of the internal medicine third-year clerkship (the clerkship), and the National Board of Medical Examiners shelf examination (NBME) is given during the final twelfth week. Internal medicine specialty societies publish a list of 20 core problems in internal medicine to be emphasized during the third-year clerkship.
