Traditionally teachers have been supreme, standing in front of the class and leading the students through the coursework. The new concept, though, is to encourage teachers to step back and let the students take center stage. The teacher would stand in the wings giving guidance and directing the students.
傳統的教學，老師是主角，在前面帶著學生走；新觀念則是，老師退居幕後讓學生站上舞台，扮演從旁協助、指導的角色。
