Awesome question. Really makes you think. This one is a keeper!
I think that one of the fundamental issues of a rubric of any kind is that it shows choices in what is valued. A teacher that designs a rubric a conscious call as to what they are valuing and what they are weighing in the assessment of work. Choices help to illuminate values, suggesting clearly that individuals are the sum total of their choices. In a rubric of the clones' artwork, one has to assume this perspective. Madame believes that the clones are human and wishes to portray this to the public. She fervently stresses that art is a window to the soul. Hence, her rubric for examining student work should reflect this. For example, there might be a section of the rubric in which Madame gauges how the artwork created "displays the emotional experience of human beings." This section could have comments in terms of what exact emotional experience is being displayed. At the same time, I think that a part of the rubric could talk about how the artwork "features abstract expression that is intrinsic to the artistic construction of a human being." In this section of the rubric, art is developed as a complex experience, something that human beings would develop. Madame could assess the artwork on this realm as well. Another aspect of the rubric could be that Madame is able to develop a self- reflection piece in which the clones write or talk about their own works of art. What does the artwork mean to them as they created it? The artistic reflection from the artist about their work is as human as one can get, and Madame could feature a part of the rubric in which the clones talk about their own artwork. In these areas, the rubric exhibits a fundamental belief that Madame has in that "through art people exhibit their souls." The clones can show this through this rubric examining their art, helping to make Madame's case for her.
