What’s Math Got To Do With It?

Mathematical Mindsets

Jo Boaler

Professor of mathematics education at Stanford University, formerly the Marie Curie Professor of Mathematics Education at the University of Sussex in England. She is the author of seven books and numerous research articles.

Both of these books are based on recent brain research and the findings of Carol Dweck, world-renowned Stanford University researcher and psychologist, about Mindset – The New Psychology of Success.

“… that everyone has a mindset, a core belief about how they learn.

People with a growth mindset are those who believe that smartness increases with hard work, whereas those with a fixed mindset believe that you can learn things but you can’t change your basic level of intelligence.

… math was the subject most in need of a mindset makeover.”

Brain research shows that:

< there is no such thing as a math gene

< mathematics, more than any other subject, has the power to crush students’ spirits.

“That single belief – that math is a “gift” that some people have and others don’t – is responsible for much of the widespread math failure in the world.

So where does that damaging idea – an idea that notably is absent in countries such as China and Japan that top the world in math achievement – come from?”

This question is answered throughout the book.

“The idea that only some people can do math is embedded deep in the American and English psyche. Math is special in this way, and people have ideas about math that they don’t have about any other subject.”

Solution: “Relatively small changes in teaching and parenting can change students’ mathematical pathways, because the new knowledge we have on the brain, mindset, and mathematics learning is truly revolutionary.”

“Studies of successful and unsuccessful business people show something surprising: what separates the more successful people from the less successful people is not the number of their successes but the number of mistakes they make, with the more successful people making MORE mistakes.”

She then goes on to tell the story of Howard Schultz who made several mistakes before finally coming up with his successful brand – Starbucks.

“I have not failed. I’ve just found 10,000 ways that won’t work”   –Thomas Edison

Also Jo Boaler explains how students do learn more from making mistakes that by doing problems correctly.

Jo Boaler’s Math Education website:

Contains “tons” of free information. One idea in particular: How to Learn Math is a free course for learners of all levels of Mathematics.

Mindset (The New Psychology of Sucees)

Carol Dweck

< parenting     < business     < school     < relationships

(I ordered this book and one of Jo Boaler’s books while I watched her speak for the first time – within 15 minutes!)

Smarter Than We Think

Cathy Seeley

Former president of NCTM, K-12 Director of Mathematics for Texas, Senior Fellow at the University of Texas.

Contains 40 messages (3 to 6 pages of essays) that can be read either individually or following an order based on themes, messages about:

  1. Who we teach and how they learn
  2. Teachers and teaching
  3. Leadership, issues and policies
  4. Thinking mathematically in a common core world – mathematical practices and more

Cathy also cites the Mindset ideas of Carol Dweck.

Embedding Formative Assessment

Dylan Wiliam

A leading authority on the use of assessment to improve education.

He taught math and physics in urban schools for seven years, head of the School of Education   King’s College in London, and was senior research director at ETS, Educational Testing Service in Princeton, New Jersey. ETS creates the SAT, AP exams, GRE, Praxis, among others.

Wiliam explains why we need formative assessment and how to implement it. His book applies to all subjects, however, since he was a math teacher, many of his examples cite mathematics teaching and learning.

My comments

I have seen all of these amazing people speak, except for Carol Dweck.

Some of them several times. I also was able to attend a 3-hour workshop with Jo Boaler and her methods are outstanding. She puts into practice what she preaches.

I highly recommend these books to you.

I also strongly encourage you to hear any one of these speak whenever you are able to do so.
