Rubrics: Trial and Error

After grading a stack of biome posters, I went over the grades and comments I made on them.  The grades were abnormally high.  At first I thought this was a good thing.  Then, when students continued to score high I began to doubt that my rubric was an accurate measure of student performance.

High grades are good only when they're a reflection of the student's comprehension.  Upon more reflection and discussion with other teachers I realized that rubrics are more sticky than I realized at first.

As I talked with seasoned teachers, they told me rubrics, regardless of how good they are or how much work went into producing them, are always too lenient the first time around.  Teachers aren't familiar with them yet, and the vague wording needs to be tightened up.  This can only be fixed after they're assigned the first time.

The rubrics were and excellent method of communicating with students.  For each project I was able to give comments and feedback on the assignment, regardless of the grade.  When I handed back the rubrics and the grades, the students received the comments really well.

One thing I would like to try is to have students grade the quality of their own work before I grade it.  One teacher does this with major assignments and she's found that the students have a good estimation of the quality of their own work.  I like that students are reflecting on their own work; it's a good step away from "doing school" and towards internalizing material.

The next time I give this assignment I'll change the wording to be more specific, still give feedback on the quality of work, and try and have the students be reflective of the work they turn in.
