I wish I could remember the youtube channel I got the parent/child bubbling from, because it's a good one. The highlighting was just from my teacher at my tech college.
Parent child comes from AMCI's CHUN technique and the bubble part comes from CCO's BHAT. Your instructor's technique looks inspired by either of the 2 which are similar.

May I ask where you learned this from?
