Yesterday, this turned up in one of the textbooks I teach from. It caught my attention because of the name Marcel (cf. my recent dream about Marcelo and Marcela) and because of its resemblance to the "Wheel of Fortune" imagery I had also recently posted about.
Elementary school kids in Taiwan are pretty smart, and when we read, "Later on, artists understood what Duchamp was creating," one of the girls said, "Oh, this reminds me of the story we read last week: The Emperor's New Clothes." Everyone immediately understood what she was implying and laughed. A boy said, "Do you see the art? Yes, yes, I see the art, too." Just as in Andersen's story, children are the first to see through stuff like this.
This led to a general discussion of fake art, and I told them about a piece of "performance art" a few years back which was just the artist sitting at a table, and you could come and sit opposite her and have her stare at you for a while. I didn't mention the name of the artist or the piece because I certainly don't want kids to go home and google Marina Abramović, of "Spirit Cooking" fame.
