Discussion Overview

The discussion revolves around the practice of peeking at answers for unsolved problems during self-study. Participants explore the implications of this practice on learning and problem-solving skills, considering both the potential benefits and drawbacks.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions whether peeking at answers should be avoided entirely, expressing discomfort with the practice despite having done it occasionally.
  • Another participant acknowledges the validity of self-studying with solutions but warns that the provided answers may not always be correct, referencing Schaum's Outlines as an example of structured problem-solving.
  • A suggestion is made to create a list of problems where answers were peeked at, with the intention of revisiting them later to attempt solving from scratch.
  • It is proposed that looking at answers after making a significant effort can be beneficial, as it may help overcome cognitive blocks and enhance learning from different problem-solving approaches.
  • A participant emphasizes the importance of ensuring that one can solve problems independently after peeking, recommending a separate study session for reinforcement.

Areas of Agreement / Disagreement

Participants express differing views on the appropriateness of peeking at answers. While some argue it can be a useful learning tool under certain conditions, others caution against it, suggesting that it may undermine the learning process if relied upon too heavily. The discussion remains unresolved regarding the best approach to this practice.

Contextual Notes

Participants acknowledge the potential for incorrect answers in solution sheets and the importance of developing problem-solving strategies. There is also a recognition of cognitive blocks that may necessitate looking at answers, but no consensus on the overall impact of this practice on learning outcomes.

Should peeking at the answer of an unsolved problem be avoided at any cost?
I'm self studying at the moment and have a document with the solutions. It doesn't happen frequently, but I have had to peek at answers a couple of times. I really hate doing it though.
Thoughts?

You are self studying. This is allowed but be aware that the solution sheet answer may not be right.

Schaums Outlines are based on this predicate. They provide complete solutions for you to follow and then later problems provide only final answers with no step by step.

One thing you could do is make a list of the ones you had to peek at and go back later and try to solve them again from scratch. Also try to develop useful check strategies.

As an example, a problem asks you to identify two vectors and from them create a third which is perpendicular to both. The check would be to test that your computed vector hen dotted with the first two is indeed perpendicular to them.

Eventually you won't need to peek which becomes really useful when you start solving original problems that no one has solved.

Hmm, making a list of the cheated ones is a good idea. And indeed, I have come across at least one mistake before.
 
There's nothing wrong with looking at the answers as long as you are still solving most of the problems yourself before looking. It can save you wasting weeks trying to solve a single problem on which you have a simple cognitive or memory block.

Looking at the answer to a problem that has blocked you, after you've made a worthwhile effort, is a good way to learn, because the effort will have awoken you to various different possible avenues to a solution, and you're more likely to remember the path used - and befeit from it in future problems - if you've already tried several and it's different from all of them.

Just make sure after peeking that you can solve without peeking, possibly during a separate study session later on, next day, before test, etc.
