Students should rely on feedback from grading. Therefore, graded work needs to be returned to the student within 48 hours along with notes or explanations of docked points. Marking an algebra solution as wrong and awarding no points isn't nearly as insightful as identifying what the specific error was (arithmetic mistake vs. algebraic mistake) and awarding partial credit. For example, a student could make a minor error such as losing track of a negative sign or making an error in addition (2+3=6), but demonstrate a strong understanding of the algebra concepts being assessed. Not all mistakes are created equal.
