Goal-based Techniques for Clinical Problem Solving


  • To develop a multimedia-rich simulation-oriented learning environment to train medical students in the management of foetal abnormalities.
  • To provide a realistic but safe learning environment in the medical domain which covers a wide range of problem situations that maintain case richness within each situation.
  • To provide a learning system which is practice-oriented and focuses on skill acquisition while also promoting conceptual understanding.
  • To advance the practice of object-oriented multimedia systems development and to develop useful reusable object components for the medical training domain.


System components include:

  • Patient Profile : Tracks basic patient details such as age, sex, race, symptoms, results of laboratory investigations, X-ray pictures, and treatment administered.
  • Monitor : Tracks the actions of the user and responds appropriately. Also grades student performance. Incorporates element of time criticality.
  • Profile Generator : Used by the instructor to specify case parameters such as age, disease, symptom severity, etc. and generate a consistent patient profile for the session.
  • User Interface : Includes areas for user input, graphics, video, prompts and questions by the system, and summary of current session.



Mission Context:

  • Mission : The primary goal the student pursues within the GBS. 
  • Cover story: The premise under which the mission will be pursued.

Mission Structure:

  • Mission focus: The overall organization of the students activities within a GBS.
  • Scenario operations: The activities the student performs in pursuit of the mission.

Strengths of a GBS:

  • Very concrete
  • Highly situated
  • Deeply experiential
  • Supports authentic practice
