## Main Question or Discussion Point

In many science textbooks the solutions to the problems are provided in the book. Doesn't this have a negative effect on learning the subject? When you try to solve a problem, and then check the answers to see wether you have the correct, when you realize that the answer is incorrect you immidiatly try to figure how to get to given result, sometimes by for example manipulating equations without even understanding the solution... And when you get used to check the problems by the answers, later on you don't use enough time thinking about wether your answer is correct or not by really thinking about the peoblem, instead you can just compare with the answeres.

Isn't this a bad effect, because when you're finally to the exams there usually aren't anything you can compare your result to, and if you haven't learned to check through your solutions by considering what you could have done wrong, i.e. is the assumptions or the equations correct, then it's more likely that you won't see the existing errors.

Doesn't this mean that your ability to check through your own solution would be weakened, by too much comparision with answers?

I'm asking this because I think this is what I'm effected by, since when I complete problems I immidiatly check the answers, and sometimes the problem/solution isn't even understood, even though the solution is correct. And I've noticed that this has made my ability to solve problems weaker.
