A recipe for finding answers to WW problems. Wouldn't work for every problem, but still.
Not really. WeBWorK and the OPL are open source. That means that anyone has access to the source.
A student that reads that will have to learn many things in order for it to be of use. The student will need to first learn to read that full post on Reddit. That is in itself a challenge for many students. Then the student needs to figure out how to do a Google search that will actually lead to the problem in question. The next step is to figure out how to access and read a file in a Github repository. Then comes the step of learning to read PG code and identifying the answer. Many problems are now encoded in PGML so the Reddit post won't be accurate on that. Even with that the student needs to figure out how to pull the numbers from the problem and put those into the formula that is the answer (the Pythagorean theorem in that example). At that point the student just learned how to work the original problem anyway. Success!
Several years ago, I had a couple of students who figured out some way to reverse-engineer problems on WeBWorK. We have only ever used WeBWorK as an opportunity for practice, with a small grade attached to it. The result of circumventing that opportunity was, naturally enough, that they failed all other aspects of the course.
