If this is the wrong forum for this post I apologize but I'm not sure of another well-suited medium for this question (and any reference to one is appreciated).
I am wondering if any research in mathematics education has been done about the value of seeing proofs in a course.
On the one hand, seeing proofs done by mathematicians seems very valuable. However this takes up time and perhaps is better discovered on one's own than seen.
On the other hand, suppose that you just discussed statements instead of their proofs and actually used the statements to prove new results. This also has merit and is more likely what we want students to do within the scope of the course and to some extent as a mathematician.
My question is:
"Has research been done in say a proofs class where one class sees proofs of certain statements and (possibly some/fewer) applications and another class only sees the statements and their applications?"
Does anyone have actual experience with this question?
The ideal answer here would be a paper reference to this topic but my searches of this have yielded no fruit.
Thanks in advance.
EDIT: Ideally a first proof course would be the topic of this question (so say first or second year of undergraduate mathematics) but any experiences would be interesting. Maybe even a second course (but something close to elementary definitions like an Elementary Number Theory course let's say where a student would have already taken a proofs course but has no other knowledge of the subject)
EDIT 2: Thanks for all the posts thus far! The ideal situation would be a study where say a class does the proof of Fermat's Little Theorem (for example; maybe more than one example) in class and maybe one instance of its use and another class does the statement of Fermat's Little Theorem and does some number of instances of its use. Then on say a final exam both classes get tested on:
- Questions using Fermat's Little Theorem
- Questions that require some sort of proof technique similar to that of Fermat's Little Theorem (maybe like a similar binomial theorem + induction type question).
and see how students differ in these respects. I suspect there's more factors involved than just seeing the proofs and that the likely situation is that this factor alone is negligible but I'm still curious. Thanks for the current references and I'll be sure to check them out!
