In Rubistar, you can learn how to guide your students to work according to their and your expectations. Create a Rubric and write a comment about how you would share it or use it with your students.

Post your ideas, your feelings, and the URL of your rubric so we can all share together your ideas.

Here is an extra thought for you:

Teachers give grades so teachers have authority. We need to establish a relationship that includes mutual trust and openness before we can expect students to express their own ideas, and self-grade, even with a rubric. What they will do meanwhile is provide us with ideas they think we would like to hear.
