This project is part of the research about an intelligent tutoring system to teach situation awareness for decision making in dental treatment. The system provides an immersive learning environment with key relevant cues as contexts of a current situation for making a decision. Student who takes a role as a dentist has to carry out the procedure by considering these contexts, applying his/her background knowledge about root canal treatment procedure, making a decision and putting the action to the virtual patient. The action and the outcome of the action reflect to different levels of situation awareness skill and decision making skill.
The project done at the BSCC in summer 2017 is related to the backend process of the intelligent tutoring system including representing the surgical procedural knowledge and the pedagogical module called the automated tutor. The surgical procedural knowledge represented in the new knowledge formalism is parsed and ready for accepting the student’s action. The automated tutor monitors the student’s action, evaluates if the action is correct from the effects deduced from the plan projection engine, and decides whether to intervene or not intervene. If a decision is made to intervene, the automated tutor must decide of teaching strategy to be used, and the content to generate. The graphs of tutor’s domain knowledge and student’s action of each step of the surgical procedure are created to be used by automated tutor to generate the content of intervention.
This project is designed by Ms Narumol Vannaprathip, a Ph.D. student under the supervision of Professor Peter Haddawy, the HWK fellow from the faculty of ICT, Mahidol University, Professor Christian Freksa and PD Dr. Holger Schultheis from BSCC, and Professor Siriwan Suebnukarn, the HWK fellow and dental expert from Faculty of Dentistry, Thammasat University. The parser, the plan projection engine, and the graph of the domain knowledge and the student’s action are developed by the undergraduate students from the faculty of ICT, Mahidol University, including Mr Atirach Intaraudom, Mr Nattapon Aiemlaor, and Mr Chontee Theemuenvai. The pedagogical process to generate the intervention is developed by Ms Narumol Vannaprathip.
