Bayesian network model

Develop structural representations of cognitive tasks, complex learning processes Cognitive task analysis Provide learning trajectories Provide info of cognitively diagnostic assessment

Structural representation used to

• effectively express cognitive task
• provide learner with cognitive trajectory

Cognitive task:

Well structured: subtasks exhibit well-graded knowledge structures

OR

Not well structured: contain latent variables, multi-represented from latent variables to evidential variables

Structural hierarchical representation

13 3rd yr med students, solve video clinical task, simulated emergency Complete case, observe problem, what would you do?

• Deep cognition
• Metacognition
• Cognitive action

Organize components into a model - evidential variables.
