My feeling of audacity is reflected in my philosophy about grading. And you will probably have him next year. My subjective measurement will ruin the whole grading scale. And when it does, you may contentedly smile knowing that your measurement had more reliability to the test than mine. Unfortunately, however, you will also know that a number of your students turned off to academia.
Grades are a powerful tool.
They can empower, stagnate or diminish your students' drive to achieve. This leads me to ponder the obvious.
