I have used the Artchive to project works of art on the theme that I am covering in my language class. For example, if I am covering physical descriptions, I might show students a portrait by Van Gogh, Munch or Monet. I would then have the students do an oral exercise describing the figure in the painting. If my subject is the family, I might choose a painting by Botero and do a similar oral exercise. The paintings in the Artchive provide good stimulus for writing as well.
Using a projector and a large screen in the classroom makes the Artchive a useful teaching tool.
