I am teaching the exercise sessions for a 3rd year algebra course (intro to field theory, Galois theory and Algebraic geometry). The format of the course is as follows: for every 2 hour lecture by the prof, I teach a 2 hour exercise session where the students are supposed to actively work on exercises and I answer their questions. In practice this often means I give quite a few solutions on the blackboard, but not all of them. There is no homework for this course, just an exam.
Preparing for this course, I made latex notes containing the solutions of all the exercises. And so my question is: should I give the pdf of this file to the students?
On the one hand, having detailed, rigorous solutions for the exercises will help prepare the students for similar questions that might be on the exam.
But, on the other hand, I am worried that if the students have all the the solutions on hand, they will not learn the perseverance needed to struggle with a new problem (as might be presented on the exam).
Does anyone have some experience with this? Do students tend to do better or worse if they have access to all the solutions?
