Discussion Overview

The discussion revolves around a student's experience with an online business math exam where answers written in scientific notation were graded as incorrect. Participants explore the implications of grading practices, expectations regarding answer formats, and the role of the grading system used for the exam.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant expressed frustration over receiving a poor grade due to using scientific notation, which was not accepted by the auto-grading system.
  • Another suggested that the grading might have been done by TAs who may not understand scientific notation.
  • Some participants noted that the grading system is automated and typically recognizes multiple correct answer formats.
  • A question was raised about whether the exam instructions explicitly stated the required answer format.
  • Several participants discussed the appropriateness of using scientific notation in various mathematical contexts, with some arguing it should be accepted universally.
  • One participant suggested that if the instructor does not allow for flexibility in grading, the student might argue that the grading penalized them for a single mistake repeated across multiple problems.
  • There was a consensus among some that if the required format was not clearly communicated, the student should receive credit for their answers.
  • Another participant shared a personal experience of being penalized for not using the expected format in a different class, highlighting the importance of familiarity with the grading system.
  • Ultimately, it was noted that the student received full credit for their answers after discussing the issue with the instructors.

Areas of Agreement / Disagreement

Participants expressed a mix of opinions on the grading practices and expectations for answer formats. While some argued for the acceptance of scientific notation, others emphasized the importance of adhering to specified formats if communicated. The discussion reflects unresolved views on the fairness of the grading system and the clarity of instructions provided.

Contextual Notes

Limitations include a lack of clarity on whether the exam instructions explicitly stated the required answer format and the potential variability in grading practices across different instructors and courses.

For a math elective. Our exams are online.

I did very poorly on the first exam because I wrote almost all of my answers that warranted it in scientific notation purely out of habit, which were all graded as incorrect.

I of course emailed the professors protesting, they will meet and talk about it apparently.

Moral:
Don't take business maths.
 
Mathematics news on Phys.org
Dang! Maybe the exams were graded by TAs who didn't know better...?
 
No, it is "auto-graded," I received my score as soon as I hit submit. Usually it's pretty intelligent at grading, there are multiple ways an answer can be typed out and still be correct.
 
Did it explicitly say which format was required ?

Not really much to do with business math, but that sucks. Hopefully you'll get it sorted out.

I don't see why a superior way of writing large or small quantities (of whatever that may be) shouldn't be used across all maths.

That's just it. It just depends what you're doing. If you deal with large/small numbers a lot, I agree. A lot of people don't like getting used to scientific notation though. I can't remember the last time I saw anyone write in scientific notation. I saw it more in physics than math classes, where significant figures are very important. Just realize this issue isn't limited to business calculus. It could happen in any class.
 
If your instructor won't budge on this point (which would be silly but it happens), you might make the argument that you made one mistake - not using the proper number format. While it's true that that one mistake is evident in many of the problems, it's still basically just one mistake. I'd argue that you shouldn't be marked down more than once (if at all).
 
I agree with lisab but if it was explicitly mentioned that you should write your answers in a specific format, you might not have a case.

Sometimes an answer simply is not enough unless expressed in the "appropriate format".

I have gotten nabbed for silly things like this.

Even so, if the professor is nice enough, (s)he'll let it slide once. It certainly wouldn't hurt to have a talk with the professor.

No, it's a very simple and basic system. It's on "mymathlab.com." I'm sure many of you have used it before. Nothing is really mentioned, you just log in and take your test.

It is textbook based, the instructor does not make the test. It is randomized questions based on the chapter's subject matter.

I would fight it then. If there's nowhere on the site that specifies and the professor didn't tell you, you should get the credit back.

I don't mean to discourage you but typically you are expected to be familiar with the system prior to major exams.

Anyway, I wish you the best on your case.

I've had it in other classes. In what way have I demonstrated a lack of familiarity? :confused:

Well, I figured you should have been aware of how the answers are usually entered and acted accordingly.

If you were familair with the software, you should have known that the answers required are usually not entered in scientific notation i.e I had an online assignment for first year physics and we were required to enter angles. After my first use of the software I found out that the program only accepted degrees and not radians. Hence, my next answers where all in degrees.

They decided to give me full credit for all answers, whew.

I would note here, that if it is based on textbooks and the textbooks have a specific notation, that should be all you need.

If for example, the textbooks have always written 1,000,000 instead of 1x106 then you should be aware what format they are expecting.

I'm glad your instructors are reasonable!
