I completely agree!!! i will say, for the first time this summer, with my summer school students (ages 6-7) I did an action painting lesson. We read the book Action Jaction and the students created giant action paintings. (I only had 11 students and we had to wash their feet after!!!). They did this lesson after an entire week of painting with their hands, plastic flies, forks, sticks, etc. We talked about how paint can show the way you are moving (rhythm) and how the different colors you use can show how you feel and create a mood.
I don't know if this is what Jackson Pollack had in mind. But I have to say, I have never seen my students enjoy a class so much as they did that entire week (the class was called "Artists with Dirty Hands"). It really has made me rethink my K-1 lessons to offer more tactile, experiential kinds of opportunities for my students. I like trying new things with the summer school students (smaller groups) to see what works and what doesn't.
I hope this feedback helps.
I have a student teacher this fall and will be recommending that she subscribe to the list. Good Luck to all of you!
