Sometimes the simplest changes have the largest impact.
Sitting with students rather than standing.
Talking less. Listening more.
Giving an extra few minutes for student thinking beyond what you normally do.
Agency is often a series of small moments leading up to larger ones.

When kids are deprived of play, their mental health suffers.
Over the past 50 years, the time kids spend playing outside and inside has plummeted. They're missing opportunities to bond, build self-control, be creative, and feel joy.
Free play is a key to happiness and growth.

Students getting “stuck” together on a task early on can do incredible things to help establish an inclusive and supportive classroom culture. In the first few days of school, which will having a greater lasting impact…reviewing the syllabus or offering learning experiences where students grow together and see the teacher having confidence in their abilities? 🤔🗣️ #mathchat #STEM @pgliljedahl

When you burn people out, you push them out. Stars are the first to leave—they have the most opportunities.
The solution is not to pile on the perks. It’s to pinpoint the root causes of overload and design more manageable jobs.
If you want to keep people, stop exhausting them.

Story is a powerful vehicle for change as it's a return to the oral tradition.
What's next in education is a return to what's been erased.

Toxic cultures exploit generosity. Takers impose extra work on givers, and no good deed goes unpunished.
Healthy cultures reward generosity. People protect givers from takers, and cream rises to the top.
Helpfulness is not a weakness to target. It's a strength to safeguard.

ALT Did You Know?: When 9th grade students wrestled with math problems to find their own solutions before receiving instruction, their comprehension nearly doubled, compared to students learning via direct instruction only. In middle and high school, asking students to struggle with key concepts before teaching the correct solutions is highly effective. But use the tactic surgically to avoid too much frustration.

I agree...and this is one of the most concise and clear statements I have read on the matter...
"It is incredibly clear that the pressures of tests and grades do not incentivize but rather hinder mathematical and genuine understanding."

In our research we found that women were told they were too young to lead, too old to lead...and middle age wasn't quite right either. As it turns out no age is the right age to be a woman leader. See my latest @HarvardBiz article for solutions.

How to study like a world-class mathematician:
1. Focused work: 3 hours in the morning
2. Daydreaming & long walks: all afternoon.

The 90% model of assessment helps us stay grounded in assessment that matters, that honours each learner, & that supports growth and next steps.
The time we have with students is a gift, not a constraint. How we spend this time is a reflection of what we value.
