In education a rubric is a set of criteria used for grading assignments.  It simplifies the way educators grade assignments, but it does take a little effort at the beginning to set up. Watch the video below for comprehensive instructions on creating and integrating a rubric into your course.

Using a rubric for grading means that your students will have a better understanding of how they are being graded, more so than (seemingly) arbitrary grading.  If you take the time to leave comments on each criterion, it also gives them guidance on how to improve in future assignments.
