Why do so many professors just do proofs in class?

Click For Summary

Discussion Overview

The discussion revolves around the teaching methods employed by professors in physics classes, particularly the emphasis on proofs and derivations versus practical applications. Participants express their frustrations and experiences regarding the balance between understanding theoretical concepts and applying them in problem-solving contexts.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants express frustration with professors focusing on proofs, arguing that it detracts from practical problem-solving skills needed for tests and future applications.
  • Others suggest that understanding proofs is essential for grasping the underlying principles of physics, asserting that it fosters a deeper comprehension of the material.
  • A participant mentions that while proofs can be beneficial, they often feel unprepared for applying concepts in homework and exams without sufficient examples or guidance.
  • Some argue that the teaching of theory through proofs is necessary for a solid foundation, contrasting it with engineering approaches that may prioritize application over theory.
  • Concerns are raised about the difficulty of exams, with participants noting low average scores and the challenge of transitioning from theoretical understanding to practical application.
  • There is a suggestion that different educational paths (e.g., physics vs. engineering) may lead to different expectations regarding the use of proofs and applications in coursework.

Areas of Agreement / Disagreement

Participants generally do not reach a consensus. There are multiple competing views regarding the value of proofs in education, with some advocating for their necessity in understanding while others prioritize practical application. The discussion remains unresolved regarding the best approach to teaching and learning in physics.

Contextual Notes

Participants express varying levels of comfort with proofs and applications, highlighting a potential gap in instructional methods that address both theory and practice. Some mention the lack of examples or guidance in applying theoretical concepts, which may contribute to difficulties in mastering the material.

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)
