I am very interested in this conversation. I work in a Children's Art Museum. I've stopped letting the staff and volunteers put out samples, because the adults would encourage the children to copy the examples exactly.
Some kids just have no idea what to do.
Others come up with wonderful creative designs. First thing a new staff member or voluteer learns is the bigger the mess the more fun they had. We are interested in setting up a desktop publishing center, with the local school district. We want this to promote creativity not stifle it. I've insisted that we include a scanner in the budget we send out for grants.
