Rubrics set standards. Students know in advance what they have to do to achieve a certain level. Rubrics clarify expectations. Rubrics help students take responsibility for their own learning. Students use rubrics to help study information the teacher values.
Rubrics have value to other stakeholders.
Howe offers some insight into this aspect of rubrics as a strategy. Quality rubrics are not cast in stone-they are revised, based on studentwork. By using student work as a basis, teachers are more likely to be realistic in their expectations of students. The measure of student achievement must be based on several similar tasks. Various researchers advocate scoring between six and 20 tasks before a determination of level of mastery accurately can be achieved.
