Here's a thought-provoking question that may prompt a fair bit of debate:
Why shouldn't students be able to get 100% on every percentage-based assessment that you do in your classroom? Most of my assessments are not formal and many are based on rubrics that I usually design along with my students so they know exactly what is expected of them and how to do the best that they can.
When I do, however, give a quiz or exam that is easily graded (mathematics being a good example), why should a student not be allowed to take that test again until they get 100%?
I am a teacher who believes in success for every student (as I am sure you are), but we often let a one-off test be the judgment of how well a student knows a particular area of study. If it turns out they don't understand it, then it's game over.
But should it be?
I always tell my students that they are welcome to repeat their assessments as many times as they wish until they get it perfect. (I change the tests slightly (unless it's spelling) but stick with the same concepts) Why? Because it's NOT about the grades. It's about learning. If a student doesn't do well, it means they haven't adequately learned the material presented to them.
If a lot of students don't do well, it probably means I haven't done a good enough job of helping them understand, and then I've got some reteaching to do; if there is a small number of students who need specialized help, that's also my responsibility to get some small group time with them and perhaps scaffold the assessment after some more practice together.)
I am always happy to tutor in the mornings (I have 15 minutes set aside for this before school each day), to send emails home to parents requesting specific help, or to do what it takes to help students achieve their personal best.
I'm not claiming perfection here: I am not as consistent as I'd like to be in this practice or many others. Time and countless other things get in the way of me achieving star teacher status. I'm sure you get it.
But if students want to achieve their personal best, who am I to stop them? In fact, isn't it my job to make sure they do so?
What do you think?
