Facilitation is just as kiethl said above. It is another tool in the armoury of an instructor but he/she must use it wisely.
About 15 years ago the RAF Central Flying School taught it on their newly formed advanced CRM course and it was used effectively as one of the tools. Extracting information is a good way of getting the team to think but it is not hte only way and should not be used when teaching new information.
These days I have seen CRMIs uses facilitation as an excuse not to do any work themselves. This is a shame as it can be used effectively. About 5 years ago I did a CRMI course at Global Air Training where they taught the use of facilitation very well.
There are some good facilitators out there who use the technique well along with other techniques.
