Introduction
Methods
Database of virtual cases
Construction of virtual learning system AIteach
Virtual medical record generation
Data extraction
Virtual medical record teacher review requirements
Natural language processing for case extraction
Student input question and answer matching
Cultivating students' clinical thinking with various difficulties
-
Level 1 provides students with a comprehensive version of the case and an answer reference to select from.
-
Level 2 provides interference and error for history, physical, and auxiliary examinations.
-
Level 3 requires students to enter more important scoring items themselves.
-
Level 4 is fully independent self-study mode. Students need to enter all diagnosis and physical examination questions themselves.
