Why do so many professors just do proofs in class?

Click For Summary
SUMMARY

The forum discussion centers on the frustration of students regarding professors who focus heavily on proofs in physics classes, particularly in Electromagnetism (E&M) and Quantum Mechanics (QM). Students express that while understanding the theory is important, they find it challenging to apply these proofs to practical problems, especially when tests require application rather than derivation. The conversation highlights a divide between theoretical understanding and practical application, with some students advocating for a more hands-on approach to learning, as seen in programs like those at NC State, which emphasize real-world problem-solving over theoretical proofs.

PREREQUISITES
  • Understanding of basic physics concepts, particularly in Electromagnetism and Quantum Mechanics.
  • Familiarity with mathematical proofs and their applications in physics.
  • Knowledge of problem-solving techniques in physics and engineering contexts.
  • Awareness of educational structures in engineering versus physics programs.
NEXT STEPS
  • Research effective problem-solving strategies in physics, focusing on practical applications.
  • Explore the curriculum differences between physics and engineering programs, particularly at NC State.
  • Learn about the role of internships and co-ops in bridging the gap between theory and practice in engineering.
  • Investigate resources for mastering mathematical proofs and their relevance in real-world applications.
USEFUL FOR

Students in physics and engineering programs, educators seeking to improve teaching methodologies, and professionals interested in the balance between theory and practical application in technical fields.

hey, poops.

office hours are essential for doing homework problems. i camped out in my profs' offices for EM2 and the grad quantum sequence!

We get a tutorial class one day a week for E&M and QM. Looks like it will be crucial.

Also, you're from Talk Bass, right?

there is only one brad barker on the internet, right? ;)

why do so many students just want problems worked in class? don't they know how to work problems on their own?

I think you just answered your own question.

If so many of them want it, they must not know how to do it.

indeed, so what is the appropriate response? give into their incapacity? or hold them to a higher standard, where they are expected to do some work on their own?

it is not at all clear that when faced with students who have no experience with doing their own work, that one should respond by babying them further.

The correct way to administer your instruction is as you indicate: Hold them to a higher standard to do their own work. The trouble with that approach is that some teachers still must worry about keeping their jobs.

...or everyone just friggin' scours the internet for scans of the david griffiths EM solution manual...

I forgot to check back to this thread but regarding the comments about my first post here, I think I was misunderstood. I meant that I think it is important to understand the proof, before plugging in the numbers into the equation. Simply understanding the proof and not using it would be kinda pointless! (In this context)
