STEM Corner: What’s a ‘Math Brain’?

Having just finished parent-teacher conferences, I reflected on my many conversations.

 

Not once did I hear a parent say, “Well, I was never very good at math, so I’m not surprised that she isn’t either.” These are words I often hear during conferences; they temporarily make my heart stop. Usually, I try to explain some of the research from the last 20 years about the plasticity of the brain. Researchers began by looking at victims of brain damage and their ability to re-learn many of the skills they had lost. The scientists then focused on healthy brains, and learned that we don’t necessarily have “math brains” or “art brains.” Our brains are ready and able to learn anything if we are willing to put in the practice. Additionally, those with a growth-mindset (believing that we can learn anything with practice) out-perform those with a fixed mindset (Boaler, 2013). One study even suggests that a growth-mindset intervention can help to eliminate gender and ethnicity gaps (Good, et al, 2003).

How do we help our students gain a growth-mindset? Or rather, what have we done to destroy it? Teachers and parents should be careful about messages we are sending. Do students believe they are genetically predisposed to certain talents? Does placing students in homogenous ability groupings affect their mindset? Mathematics, or any subject, takes time to learn: time to practice, to make mistakes, and to make sense of those mistakes.

I asked Miranda Hirst, one of my current AP Computer Science students, to reflect on her math journey, and how she discovered how to learn mathematics.

“When I started 6th grade, I really enjoyed math,” she said. “I was good at it, and was at the top of my class. When 7th grade rolled around, even though I was excited about Algebra 1, I quickly started having difficulty understanding the material. I stopped enjoying math as much, and by the end of the year I felt like I had barely made it through the class in one piece. I would write down what was on the board without ever really understanding what it meant. The summer before 8th grade, I was not excited for math class at all. I felt like I was not able to do math any longer, and thought maybe there was just something wrong with my brain. But my math teacher would not let me give up. I went in before school to work with her on homework. I practiced and practiced. Eventually, my love of math returned. I learned how to figure out and understand math. I learned how to problem solve. Once I arrived at high school, I had fallen in love with math all over again. Now, even if I struggle with something, I know I’ll be able to figure out how to do it.”

Everything takes practice, and practice takes perseverance. Knowing (and believing) that we can learn through both our right and wrong answers gives us the momentum to forge ahead. I am thankful that none of the 50 parents I talked with last week had the attitude that their student will never be good at math. Together, students, parents and teachers can create a growth-mindset in every classroom and in every subject.

Math activities that don’t need a “math brain”*

Which one doesn’t belong?

After you’ve decided which dog you think doesn’t belong, ask some friends which dog they think doesn’t belong. Do you agree? Disagree? How do you justify your choices? What do you think of your friends’ arguments? Who’s right?

Now try this puzzle below? Which shape doesn’t belong?

Both of these math puzzles come from the Which One Doesn’t Belong website at http://wodb.ca/

As you may have deduced and the website spells out, “There are no answers provided as there are many different, correct ways of choosing which one doesn’t belong.” Justifications can be made for why each of the four objects doesn’t belong with the others. Isn’t it liberating not having to worry about coming up with THE right answer? Go to the website and have fun figuring out all the different “right” answers and, then, make up your own puzzles with drawings, pictures, or actual objects. Have fun!

*I hope you’ve realized that the title of this challenge is a misnomer. Math skills of categorization, comparison, analysis, and sequencing are all very much needed for these puzzles — and we all have the “math brains” that can do that thinking; we just have to use them.
