About Section
Built by a Teacher, for Teachers
I’m Oskar Cymerman, a teacher, writer, and creator of Crush School. I write about teaching strategies that help students become better thinkers, stronger learners, and more independent humans.
My goal is simple: create tools teachers can actually use, explain why they work, and make learning feel more active, meaningful, and doable.

I write articles about teaching strategies that move the learning needle and sprinkle some personal life on top to better understand, and hopefully help others understand, how these things intersect, challenge, and help uplift teaching and learning.
I write about:
Science Supported Teaching and Learning Strategies.
Fostering Student Agency, Free Thinking, and Success.
Building Transferable Skills.
In my posts, I explain the what, the why, and the how of various experiences and strategies, and usually give resources teachers can use in their courses. Some are free and some live in my shop. I hope they help.
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. ”
“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.”
