Discussion Overview

The discussion revolves around interpreting a specific format used in a college course catalog that lists courses with associated credits and a vector representation. Participants explore the meaning of this vector notation and its implications for course structure and expectations.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants express confusion about the vector notation, with one participant asking how to read it.
  • Another participant suggests that the vector might represent course weight, indicating hours for lectures, labs, and study time.
  • One participant proposes that the notation could vary by college, suggesting multiple interpretations for the meaning of the vector components.
  • There is a mention of the term "vector" being potentially misleading, as it is described as a 1-dimensional array of numbers.
  • A participant speculates that the vector could relate to different educational paths or directions within a mathematics program.
  • Several participants joke about the situation and suggest reaching out to professors for clarification.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the meaning of the vector notation, with multiple competing interpretations and a general sense of uncertainty about its significance.

Contextual Notes

Limitations include the lack of specific definitions for the vector components and the absence of a clear legend in the course catalog that could clarify the notation.

Like in my college, courses often are written in a list like this


Name = Credits = Vector

Math = 3 = [0-3-1]

How do you read it?
 
Mathematics news on Phys.org
What the hell??
 
I certainly thought I did until I read this...

LOL, my thoughts exactly.
 
Isn't that just course weight?

Usually, [3-1-0] could mean that you're expected to attend 3 lecture hours, study for about 1 hour, and you have 0 hours of labs. It was like that at my former college.

Then you should ask somebody at your college what it means. I suspect it probably means something like "3 hours lecture, 1 hour lab, 0 hours recitation." Or maybe "3 hours lecture, 1 hour recitation, 0 hours lab." Or maybe "3 hours lab, 1 hour lecture, 0 hours recitation." Or maybe...
 
I don't know who to ask, I am away from my college's city right now.

Each lecture runs an hour and a half long but we have it three times a week. No such thing as recitation in our college, there aer labs which does run 1 hr

Well... not us. Whatever that is, it's probably something specific to your college.

Also it really irks me that it's called a "vector."

But it is a 1-d array of numbers!

...and the norm represents how much time you spent on the class!

[randomfact] In C++, a vector is just a 1D array of any object[/randomfact]

I guess that usage is grandfathered into my psyche :-p

Can't you shoot a professor an email and ask?

Any professor?

For some reason that's what popped out at me reading that post...:eek:

Well, maybe then you could ask as you're being dragged away to jail.

I'll take a stab at it...

I'm guessing that you're referring to a course catalog published by your university? I'm also going to assume that you're not using the standard, mathematical definition for the '=' sign because I can't see any reasonable equivalence between the names, numbers, and symbols in your post.

Since the word "vector" can, essentially, mean a course or direction, is there a legend on the catalog that would explain why the '1' has been assigned to the math course to which you're referring? Perhaps there are different "directions/paths" one can follow that would correspond to specific courses? (Pure, Applied, Discrete, etc.)

For example, math courses that are typically taken when pursuing a degree in pure/general mathematics might be assigned a "vector" value of '1'. Then, when the student is looking through the catalog, they can easily identify electives/prerequisites that would be congruent with their educational goals.

That's the only interpretation I can come up with at the moment.
