How to solve the art classroom teaching mode of a single formalized

Whenever someone asks me what subject I teach, I say art. As soon as they hear that they teach art, they say, "That's good! Art class is very easy, good, just let the students draw a picture, and do not have to talk much, a lesson will soon be over." Yes, I remember the art class when I was in elementary school, and it was indeed this kind of teaching mode. But nowadays, when I stand on the podium, the feeling is not the same. Now the art classroom, breaking the traditional art teaching knowledge framework, advocating a new way of teaching and a new concept of education, emphasizing the learning of comprehensive art activities, guiding students to take the initiative to explore, create on their own, the use of comprehensive knowledge and skills to produce, performance and display works, arousing the students to the unknown areas of the desire to explore, to experience the pleasure of it, and to enjoy the sense of achievement brought about by the creation. Teachers cannot teach according to the previous teaching mode. So in the eyes of others may seem easy, but I do not think so.
