So far, I have learned that rubrics are helpful to the students to guide them in the development and production of their work, and they are also helpful to the teachers in planning the instruction, staying focused on the objectives and in evaluating the learning and the instruction. However, rubics can be complex to develop. The more holistic the rubric, the less helpful it will be in defining especific expectations; the more analytical the rubric, the more time-consuming it will be to prepare and the less useful in evaluating creativity and other factors affecting work, such as effort and time spent.
I look forward to using rubrics to help clarify work expectations for my students and to help focus my instruction.
