I just read through the February issue of New Art Examiner and found
several references for some of the questions raised on this list lately.
In particular there is a good article on critiques called "You Call That
Art? A Critique of the Critique" by Micheal Bulka. There is also several
good reads on working with inner-city kids.
This issue of New Art Examiner is their annual look at arts education. I
always find the perspectives of the articles in this special issue
interesting and refreshing in that they're typically away from the
mainstream of art education.
