Abstract | Problem-based learning (PBL) has become a popular approach for teaching in medical schools due to its effectiveness in imparting clinical reasoning skills. But the PBL does not make very efficient use of the instructor's time since it requires an instructor to spend large amounts of time with small groups of students. Recently the COMET intelligent tutoring system was developed in order to automate the process of medical PBL so that students may obtain more practice than is available with the instructors' limited time. COMET generates hints to guide group problem solving by observing student actions in creating the problem solution. As is typical in group problem solving situations, students engage in a significant amount of discussion before and during the process of crafting the solution. This discussion takes place through COMET's group chat facility. The automated tutor could make more timely and more effective interventions if it was capable of understanding the students' chat. This thesis develops and evaluates a system that can track such chat. The system makes use of the UMLS medical ontology to extract and analyze the medical terms in the chat. The system is capable of identifying what topics the students are discussing as well as when the topic changes, with a runtime performance that is sufficient for practical application. Evaluation is conducted on chat logs from COMET and transcripts of taped human tutored PBL sessions at a medical school. |
