Here it is, a beginner program explained in detail, with video, on terrain designed specifically for this program.
This video is used to train rookie instructors at Killington, in VT.
TBL=Terrain Based Learning
This video shows 1 two-hour lesson, the first in a package of 3 or 4 such lessons, that beginners can sign up for. They can choose to take each lesson on any day that suits them during the season.
The narrator says this progression is not rigidly followed.
As such, I take it as a "reference" progression from which instructor-generated deviations are common.
Any comments on how these beginners are taught and how this terrain is used?
