This document discusses the use of probing questions when working with individuals to evaluate their knowledge, help them learn, and check for comprehension. Probing questions require the individual to elaborate on earlier responses and indicate that the original response was incomplete. Examples of probing questions provided include asking what will happen if a statement is true, what made them think of an answer, and what the opposite position would be. The document emphasizes letting the individual do the work of thinking for themselves rather than just being shown answers.
