Point-Based Grading Systems: Benefits and Liabilities
If there’s a perfect grading system, it has yet to be discovered. This post is about point systems—not because they’re the best or the worst but because they’re widely used. It is precisely because they are so prevalent that we need to think about how they affect learning.
It would be nice if we had some empirical evidence to support our thinking. I’m surprised that so little research has been done on this common grading system. Does it promote more effective learning (as measured by higher exam scores or overall course grades) than letter grades or percentages? Does it motivate students to study? Does it make students more grade oriented or less so? Does it provoke more grade anxiety than other systems or less? Does make a difference whether we use a 100-point system or a 1,000-point system? We all have our preferences—and sometimes even reasons—for the systems we use, but where’s the evidence? I can’t remember reading anything empirical that explores these questions—if you have, please share the references.
