General Musings about using Technology to Teach with Images by two art
historians Beth Harris & Steven Zucker
Here is what David Gran wrote about it (Carrot Revolution Blog)
smARThistory has another answer to this question. Hosted by two art
educators from the Fashion Institute of Technology, the smARThistory blog is
more than just a resource for interesting videos about art history (although
it is that as well). It also provides an excellent example for communicating
with students. The website contains art history videos that students can
watch on their own computers or download to their ipods. They have a walking
tour that students can listen to on their pods outside of class. In
addition, they have a wealth of interesting articles about art education and
technology.
While it may be difficult for you to put video in your blogs.... You
can put thumbnail images of artwork you are discussing (link to larger
images on line). Putting a thumbnail image does not violate copyright
(if you apply the four "tests").
