We present an educational tool for bringing the in­ formation contained in a Bayesian network to the end user in an easily intelligible form. The banter shell is designed to tutor users in evaluation of hypotheses and selection of optimal diagnostic procedures. ban­ ter can be used with any Bayesian network contain­ ing nodes that can be classified into hypotheses, obser­ vations, and diagnostic procedures. We present algo­ rithms for determining optimal diagnostic procedures and for explanation generation.
