CRUSH SCHOOL

I blog on Brain-Based Learning, Metacognition, EdTech, and Social-Emotional Learning. I am the author of the Crush School Series of Books, which help students understand how their brains process information and learn. I also wrote The Power of Three: How to Simplify Your Life to Amplify Your Personal and Professional Success, but be warned that it's meant for adults who want to thrive and are comfortable with four letter words.

Crush School Testimonials

The author’s style reminds me of Malcolm Gladwell in that he combines a little science, a little wit and lot of his own brilliant mind to create a book that turns the seemingly obvious, but surprisingly difficult into the totally understandable.
— Kelly, a CEO
Speaks right to teens. Thank you for saying everything I’ve been trying to tell my son in a language he understands! Easy to read and understand. Short and to the point. Great for the short attention span of teens.
— Christine D. Israel, a parent and teacher

Mistakes Are... Poster
$3.00

In this classroom Mistakes are Expected, Respected, Inspected, Corrected!

Learned helplessness is a result of years of conditioning that mistakes are bad for learning. Nothing is further from the truth - some of the most powerful life lessons come from making mistakes, reflecting on them, and growing as a result.

This is a PNG Poster you can print and display in your classroom to encourage a culture of risk-taking and learning from mistakes.

3 Memory Palace Lessons
$3.00

Flashcards are okay but there's a better way. The Memory (or Mind) Palace Method is a powerful learning and memorization technique that when mastered allows a student to remember 10, 20, or even 30 vocabulary words or concepts (definitions included) with ease.

And, they actually remember what they learned using memory palaces! This series of lessons (which can be used as classroom handouts) walks students through creating their first memory palace, filling it with information they need to learn, and using it to train their memories. It also contains short readings, a video lesson, memory palace examples, and practice drills.
