Often I see students I’m working with struggling to recall something, and drawing a blank. Usually they remember that they had seen an example of the process that would help them with their current math problem and they’re trying to remember exactly what it was, and how it starts. When I see this, the advice I give is, “Don’t try to remember. Try to figure it out in a way that makes sense to you.”
I think this has two advantages. For one, I feel like I am more likely to remember something if I am actively playing around with related information, rather than trying to recall by brute force. Often if I start doing something, anything, on a problem, it will jog my memory and I will suddenly remember what I had forgotten.
Also, of course, I feel like the process of trying to figure out a problem anew – especially one that is somewhat familiar – deepens the understanding and helps build a quicker recall the next time a similar problem is encountered.
I mentioned this to a friend of mine, and she said she refers back to this mantra even when trying to remember simple things like where she put something or the name of something. She runs through related information, often talking through it aloud, and that process helps her find the right mental pathways that lead her to recall the information she was seeking.
I’d be interested in hearing everyone’s thoughts about memory and recall. What techniques work for you? Do you think your own memory has been a strength throughout your life or has it been something you’ve struggled with it? What helps you commit mathematical knowledge to memory? Is it different for you than learning other topics or types of information?
