Here is another great resource for history Art teachers and students. ArtBabbel is an excellent platform that features a treasure trove of videos on art and artists from more than 50 cultural institutions from around the world.
ArtBabble is a good place to learn for everybody who loves and has an interest in art and particularly for educators who can use it as a way to support their classroom activities. There is a special section in this website called "For Educators" which includes several art lessons designed specifically to help teachers better integrate Art in their teaching.
ArtBabble brings art content from different places and perspectives together, easily accessed and found. It was created in 2009 and was conceived, designed, programmed, and launched by a cross-departmental collection of individuals at the Indianapolis Museum of Art.
