During Martin Luther King, Jr. weekend, I attended a Montessori conference for school leaders. Our quest speaker was Sam Chaltain. Sam is a partner at 180 Studio. He is committed to life-long learning and changing the story of education. Sam was a classroom teacher and has written several books about American Schools. During our time together, we reflected on our Montessori practices, our schools, and how we measure success. We often think about the success of our students and how they progress in their executive function skills and their accomplishments according to our set of measureable outcomes. We measure success in our enrollment rates and teachers’ longivity with our school. We measure our success with parent participation and sharing their happiness with others. How do you measure success? Watch this video that Sam shared with us last weekend.
