I have taught undergraduate mathematics for 20 years, and have written two research-informed books for students who are making the transition to undergraduate mathematics.

If you are interested in learning more about your own learning, you might also like to read this article. It explains a series of research studies about expert and novice mathematical reading, including evidence on how mathematicians and undergraduate students focus their attention differently when reading proofs (see the images below – which line do you think contains the error?). If that whets your appetite for research in mathematics education, have a look at my page about PhD study.
