what difficulties have you met in the use of scoring rubrics?
1.) They don't always take outside circumstances into account
If you have a student who tries hard but has learning problems, a rubric may not be the best tool for you. Rubrics only take into account the finished product. [ Unless you make a point to include credit for effort and time, then most rubrics won't count these elements. For most students, this doesn't matter. But if you have students
with learning disabilities, you may want to consider scrapping the rubric tool or redeveloping it so it takes into account things like progress, effort and other outside circumstances.
2.) Can be too analytical for artistic projects
Most teachers find that a rubric can be tailored for any kind of student project, but artistic work is the hardest to grade with a rubric. There are so many intangible factors in an art project- creativity, inspiration, personal history- that grading with a rubric can seem impossible. You would almost certainly be forced to make assumptions about student work, and this could lead to disputes about grades. Don't force a rubric onto an art project; if you can develop one that works, great, but don't turn art into an analytical field- you won't get the best results.
