Art is meant to be shared and students make better art if they know there's a chance each piece will have an audience. Besides, it is an art standard for students to learn how to display their work. I start putting the best work from each student aside, at the beginning of the school year, so that I there is always enough to put together a show or enter student work in competitions. In the past we had an annual student art exhibit, but this year, we had three shows, two in the Spring: March….
...and May. Rather than buying frames, I reuse the frames around the school that have been holding the same student work as long as anyone can remember (including people who have been there for 15 years).
I am trying to swap out 1/3 of the frames each year so that every 3 years there is a fresh body of work by current students. I think it's important for current students to feel that they are a part of the school with contributions to make.
Shout out to Professor Richard Curtis, who recently had his Thomas College Art students figure out how to make tactile images for the blind. He sent a box to the Academy for the Blind, full of mini canvases filled with line art done in puffy paint, glitter glue, and sand as a gift for my students. The assignment was great lesson in line, texture, problem solving, and some of his students even bothered to learn how to spell some Braille words. My students loved choosing a tactile treasure to take home.
