What are authentic assessments?"...Engaging and worthy problems or questions of importance, in which students must use knowledge to fashion performances effectively and creatively. The tasks are either replicas of or analogous to the kinds of problems faced by adult citizens and consumers or professionals in the field." -- Grant Wiggins -- (Wiggins, 1993, p. 229).
Then to prepare for our Quarterly Data Presentations, I would import the numbers into MS Word graphs or PowerPoint to get some cool graphics (Not cool). That was after I add up all the test scores, divide... you know the drill. It was time consuming, and it was stressful! Stressful or not, doing this. . . collecting the data allowed me to advocate for my art program by sharing the legitimacy of standards-based Art Ed. We all know how important it is to advocate for Art Ed.
Use RUBRICS with numeric values to collect data.
Each student gets a rubric at the beginning of a project and I'll review it with them, so that they're aware of what the mastery criterion is, and can be more in charge of their educational choices. I like to have them tape it into their sketchbook/journal for regular reference. The project rubric data should have some correlation to the pre and post data. If not you may have to look at your instructional strategies. Imagine, it's like a road map to your students.
With all that said, here's what I've learned:
I hope this helps you with assessments, and data collection in your Art Ed classes.
