Discussion Overview

The discussion revolves around the experiences of students transitioning from Calculus to Linear Algebra, focusing on the confusion and self-doubt they feel despite achieving high exam grades. Participants explore the nature of mathematical understanding, grading practices, and the emotional aspects of learning advanced mathematics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants express that they find Linear Algebra concepts more confusing than those in Calculus, despite performing well on exams.
  • One participant suggests that higher-level math classes may have softer grading curves due to the perceived capabilities of the students enrolled.
  • Another participant shares a positive experience in high-level math classes where grading is less emphasized, suggesting that this could alleviate stress and enhance learning.
  • There is a sentiment that the difficulty of advanced classes leads to a state of "constant academic confusion," yet students still achieve high grades.
  • Some participants reflect on their feelings of self-doubt regarding their understanding of the material, contrasting their confidence levels between Calculus and Linear Algebra exams.

Areas of Agreement / Disagreement

Participants express a range of experiences and feelings about their understanding of mathematics, with no consensus on the reasons for the confusion in Linear Algebra despite high grades. Multiple competing views regarding grading practices and emotional responses to learning remain present.

Contextual Notes

Participants mention varying experiences with grading curves and the expectations of understanding in advanced math courses, indicating that these factors may influence their perceptions of their own abilities and the difficulty of the material.

In the Calculus I - III, the concepts didn't seem so difficult but the highest I would be able to make on an exams would be a high B and a majority of my tests have been lower B's.

But when I got into Linear Algebra, the concepts had the potential of creating headaches and I went through class with "absolute confusion" however, I would get A's on the test (and I'm still continuing that streak and part of the three of our class that usually sets the curve on tests).

What's wrong?
 
Mathematics news on Phys.org
higher level math classes have softer curves. calc I-III was probably filled with math, chemistry, physics majors, and engineers, with a wide range of abilities.

higher math classes usually have only math and sometimes physics majors, and most of them are supposed to know what s going on. so there isn t as much need to curve people down.

i have had very high level math classes where they do not grade you at all. everyone gets an A. the assumption is you wouldn t be there if you weren t very capable.

Oh man that's so cool, that would be such a releif to just be able to go to class and learn the stuff for learnings sake rather then have to be sweating tests all the time.
 
Confusionism is considered an intellectual philosophy, you know.

Actually, I believe you may have discovered the beauty of math, if not a more understanding professor and more favorable curves in Linear.

I wish that they did that in my pure maths modules.
 
Well, it really wasn't an issue of the curve because even without the cruve, I would still manage with an A (I never got an equal distribution of the curve).

I'm just wondering why I do decent on a test I still have self-soubt about but, so so on a test where I could do way better.
 
it is this kind of feeling about maths, that make people like me get addicted to maths...it a good feeling!

Did you find that the LM or the Calculus tests actually went better? Which did you feel most confident about when you stepped outside the exam?
 
Stuff just gets a lot harder, and they don't expect the class to understand it as well. I had some advanced phys classes in college where I would finish a test and think, "That's it, I failed. Everything I wrote down was BS... I didn't even understand what half the questions were asking." Then later I would find out I got an A or something. Eventually you get used to this state of constant academic confusion. ;)

I felt more confident with my Calculus tests. In Linear Algebra, I walk out worried and frustrated. What's strange is that I ended up with the higher of grade (where half the class failed).

That's my situation. :smile:
