I currently have one student (I have a few others that are similar, but a less extreme) who has around a 10% as a homework average, but he manages to get 90s on all the tests. Tests/quizzes are worth 80% of the grade in my class and homework/classwork is worth 20%. This student averages a C, even though his test/quiz average shows "A" level understanding of the material. He just gets the material based on paying attention in class, and sees no need to do the practice. (And yes, I have tried giving "differentiated" homework to offer a challenge if the regular homework is too easy or boring for him, but he didn't do that either. My homework is also generally very short---takes less than 20 minutes...usually around 10-15. ) What do you do for students like this? Would you consider giving him a grade higher than the one calculated? I've thought about at least bumping him to a B, but at the same time, I want him to learn to be responsible and don't want to reward him for blowing off the homework. This would set a dangerous precedent for other students so I will most likely not do this.
