DOES NOT COMPUTE!
Rubric.... Sounds allot like robot to me...
So here's the question? Does using a
robot justify how a student should be graded. I'm sorry, I meant to say rubric***.
Me, I personally have always felt that there are certain subjects that require a rubric and there are certain subjects that should just use it as a (loose) guideline.
For example;
Special Agent James Bond must know how to disarm a Mark 27 Naval nuclear warhead before it's launched from the United States (by hostel British terrorists that took over a US submarine) to Russia, which in turn would cause WWIII.
Unfortunately, James was too busy hanging out with beautiful ladies that happened to be mixed in with the wrong crowed to open the disarming manual. As a result of this, James failed his Mark 27 Disarm test. In the simulation, James cut the green wire instead of the pink one which caused the warhead to detonate killing thousands off the coast of Alaska.
Here is a perfect example of where a rubric should be used, enforced and studied. For a skill set that requires exact details and measurements, a rubric should be used in order to score a test or performance.
Maybe a more realistic example would be a surgeon. You better hope that a brain surgeon was graded on a rubric before performing a brain tumor removing lobotomy. Or an EMT was graded on a rubric when demonstrating exactly how to use defibrillator and do CPR.
Then there are places where a rubric should be used as a guideline NOT as a standard.
For example;
Johnny is taking a 10th grade Beginner Group Guitar class. Johnny is taking this class to fulfill an elective and because he has always wanted to learn how to play an instrument. For his final, Johnny is required to play a Bb scale (which he nails) as well as several other scales. He is also required to play two pieces. One of which has several Bbs' in it.
Well, Johnny does a great job with his first piece and all his scales but plays 2 B naturals instead of Bbs' in his second piece. He got the other 15 Bbs correct and everything else he played note for note. After the piece, Johnny said to his teacher that he "missed 2 Bbs'", demonstrating that he understands where he made his mistake and what he needs to do in order to fix it. The professor has heard Johnny play this song over 15 times correctly (while practicing in class) but according to the rubric it's a -10% point deduction for every note missed.
Here is the perfect example of a situation where a rubric is a ridicules thing to live and grade by. The point of the class is to teach students how to play guitar at a beginner level. Johnny, who has attended all the classes, has always been prepared and who has clearly studied all the materials, grade is now in jeopardy because of a rubric.
Does this rubric, this test really demonstrate ALL of the information that Johnny has learned over the course of the semester? Does this rubric decide if Johnny really did all his work?
This is where the teacher needs to ask himself/ herself "Should this really effect his grade? He has studied everything he was supposed to and demonstrated his knowledge of the content over the course of the semester. Should those 2 Bbs' really effect his grade?"
OF COURSE NOT!!!!
Johnny clearly knows what he did wrong, he knows how to fix it. He's not taking this class to perform live, its not "Guitar Performance class". He is taking it to learn how to play the guitar. Johnny has demonstrated that he has absorbed the content over the semester. He has also demonstrated that he can play guitar at a beginner level several times before his final. Therefore Johnny did what he was supposed to do, effective demonstrate his knowledge of the content. Therefore in my opinion, Johnny should receive an A.
All in all,
There are certain subjects where a rubric is necessary. If you are teaching a specific skill that takes precise calculations in order to get a proper outcome then yes, live by your rubric. If one must perform a specific skill with an exact outcome and that's what the course is for then a rubric is necessary. A rubric should only be used when teaching factual user information that demonstrates the students ability to carry out an exact task.
But then there's other subjects, subjects that are more tuned towards a bigger picture, such as History. When teaching a subject such as history we have to ask ourselves, "Does the student understand the big picture? Have they demonstrated that they understand why this has happened? How it happened? When it happened?" If the answer is "yes" then a student shouldn't recieve major drop in their grade (according to a rubric) because he/she got the names of the guns the soldiers carried in WWII wrong or because they misspelled a few words on a test.
We have to ask our selves, "Are we programing robots that perform tasks and do calculations? Or, are we teaching students to periodically demonstrate their knowledge of the content over a course of semester. Do they understand what the big picture is? Are we going to penalize them for small details that may not be detrimental to the actual subject? Does a test really demonstrate everything they have learned? Is taking a single test really a proper way to asses all the students?
When you answer those question, then you should decide how to use your rubric.
