AI Thread Summary
The discussion centers on a teaching assistant's policy of not awarding 100% on lab reports, believing that it encourages students to strive for improvement. The TA argues that a score of 99% prompts students to seek ways to enhance their work, while a perfect score might lead to complacency. This approach raises concerns about fairness, particularly regarding consistency in grading across different performance levels. Critics argue that grading should be based on clear criteria, and if a student meets those standards, they deserve a perfect score. They emphasize the importance of uniform grading practices and the potential demotivating effect of nitpicking high-achieving students. The conversation also touches on the subjective nature of grading, particularly in areas like neatness and organization, suggesting that a rigid grading system may not accurately reflect student performance. Overall, the debate highlights the tension between encouraging student growth and maintaining fairness and clarity in grading standards.

It took me a while to get what you are saying here, or at least I think I get it. While technically it's unfair that students in other lab sections can earn a higher grade in the same course for the same quality of work, for all practical purposes I can't imagine there's any significant difference from this policy. It only affects a small fraction of students (those getting 99's and 100's), and only changes the grade by 1 percentage point on something that likely counts for a quarter or so of the total grade -- so around 0.25% in the overall grade.

The point is not the amount of bias but that there is a systematic bias which isn't fair. Random biases and mistakes are fine but not a systematic bias.

This is the longest way possible of saying you think its too much work to stick to your grading standards.

Sure, if you want to put it that way. But extra work for me also means extra money spent to pay me to do it; and the university administration isn't going to be happy if I double the time it takes to mark each log book for the sake of removing a small bias. It is just not worth it.
