Hypermedia and Educational Systems. Systems for Enhancing Medical Education: Mapping Student Search Paths Through Immunology Problems by Computer Based Testing

The development and use of uncued computer based testing in Immunology has encouraged second year UCLA medical students to become more independent, active learners and problem solvers. We have used the Windows-based IMMEX software this year to show that these problem solving exercises are a valid form of testing and that student performance did not correlate with computer anxiety or performance on objective examinations. More importantly, we have developed a graphical display of the student's solution path through the problems which allows a visualization of the problem solving processes associated with successful or unsuccessful solutions. This approach provides an analysis of the student's reasoning about complex concepts in immunology and will make it possible in the future to specifically and personally address each student's educational needs.
