I changed the compiler used (students submit the .c file and the auto grader compiles it) and with the new compiler a parse error occurs if any declarations are made after any non-declaration statement(s), so some students' code no longer compiles. The student errors are rooted in a language version technicality. It is not ethical to give anyone a zero, or ...

If a specific test case was marked as passing or failing in the sample validation, it should still be marked the same in the final way that you grade. Ideally you would also have text explaining that the sample validation only tests SOME test cases and the final grade will be based on a much larger set of test cases or criteria, but I suspect it's a moot ...

This is more of an extended comment on the effect of auto graders and especially problematic ones. First an example that is a bit extreme, just to make the main point. Suppose I give a multiple choice test that is auto graded but also permits the student to take the exam multiple times and only submit one of them. What does that emphasize? In fact, I ...

My suggestion is to: Give them a grade that matches the initial auto-grader. Also tell them that there's something in the requirements that the auto-grader failed to check for. As part of the next assignment, give them a task that builds upon the current one and can only be accomplished if they also meet that specific requirement you initially didn't check ...

Now that I've changed the script many students now have a zero (including a few who previously scored perfectly). ... because on the one hand students could go back and change their submissions as many times as they liked prior to the deadline I don't see how (2) matters here. Here's what's effectively happening here: If I was in your class, I ...

You seem to have put yourself somewhat between a rock and a hard place. The rock is when you keep the auto grader at its previous value. This approach disrespects your intent to have performance based on students doing exactly what you ask. The hard place is when you change the auto grader to the newer value. This approach portrays that your grading metrics ...

I guess whether it's strictly speaking "wrong" depends on how you communicated before (i.e., could a reasonable student interpret your grading script as part of the assignment spec, or the ground truth about how your instructions are to be understood?). However, pretty much independently of how you communicated, you will get a lot of backlash if you provided ...

If any student feels disadvantaged by this, then you will have an uproar and complaints to administration. You describe a system in which they depended on the actual thing you built not some "instruction" you gave. I would guess that you are stuck with the thing for this group of students, both practically and ethically. Otherwise grading will seem chaotic ...

What most people fail to understand is that a 70% in the UK scale does not mean you only got 70% of the exam correct. A score above 70% is something outstanding that very few people manage to achieve, that's why it's considered equivalent to much higher percentages in other countries. If you get everything correct on an exam you will get a 69% (happened to ...

I feel your frustration. I was aiming for the highest honours rank for the University-entrance examination in my country and, due to extreme stress during the examination period, I almost miss the high honours. Not that it really matters, but it bothered me and stressed me for a long time, and friends teasing me didn't help. A grade is just a picture of ...
