The Fatal Flaw of Grading: Why Your Averages Lie
Description
Are you unknowingly using a grading system that actively punishes student growth? In this episode of Your Morning Boost, we continue our deep dive into grading reform with experts Dr. Chad Lang and Dr. Matt Townsley. They expose the mathematical flaw of traditional averaging—specifically, the disproportionate, damaging impact of the zero on a student's final grade, which often represents a lack of submission, not a lack of learning. The discussion tackles why "Hodge Podge grading" obscures the truth about student progress.
The Crucial Question: What's the clearest step you can take to stop averaging from diluting competency?
Key Takeaways:
The zero has a six times more disproportionate, negative impact than a perfect score has a positive one.
Why a grade based on an average of compliance, effort, and knowledge is not true communication.
An immediate, actionable step: Replace the numerical zero with a non-numerical "missing evidence indicator" to preserve the integrity of the academic grade.
The clear alternative: Disaggregate the data and use descriptors (like Beginning, Developing, Proficient) to communicate mastery of specific standards.
