To explore the practical characteristic of Innovation and Creative Thinking course inte-grated with challenge based learning (CBL), Flanders Interaction Analysis System was used to analyze the class interaction of Solution Identifying and Implementation Context. It was shown that the class was con-ducted in open free and safe environment. Students were the center and involved in the class highly. Inno-vation and Creative Thinking course was helpful to nurturing the ability to innovate and create among nurs-ing students.
