Prompting

Prompting: an explicit verbal reminder to engage in a specific interactive process, such as explaining. Here is an example of prompting for individual self-explanations (from Hausmann & Chi, 2002):

Text:	58. Renal circulation is the subsystem of systemic circulation that moves blood through the kidneys and back to the heart.
Student:	Ok, but why to the kidneys?
Tutor:	Could you elaborate on what you just said?
Student:	I don't understand why there's a system of the systemic circulation that directly relates to the kidneys.
Tutor:	Please click the "Next" button.

From this example, it is evident that the student interacts more deeply on the second turn because of the prompt. If the student were not prompted, then it is likely that she would have stopped interacting with the material after the first turn.
