Mentoring and Coaching
Today, I share a guest post by Margot Schou, who I had the good fortune of mentoring at the start of her career. With her permission, I inserted footnotes with links to some relevant further reading on my blog, website, and in the book I co-authored with Professor Robin Pemantle (There is No One Way… Continue reading Mentoring and Coaching
Integrating Argumentation Seamlessly
In Part 1 of “Integrating Skills Seamlessly”, Frank Cassano and Anya Sturm discussed the importance of explicitly teaching the skill of problem solving, and shared powerful strategies to do that. In this post, they focus on another skill: constructing well-justified and well-organized arguments. I’ve always agreed with this goal, but my approach consisted mostly of… Continue reading Integrating Argumentation Seamlessly
Integrating Problem Solving Seamlessly
Frank Cassano and Anya Sturm are math teachers at Marin Academy, an independent high school in San Rafael. They presented on "Integrating Argumentation and Problem-Solving" at the California Math Council Northern Section meeting in Asilomar last December. I quite enjoyed their talk (which I reported on here) and asked them to summarize it as a… Continue reading Integrating Problem Solving Seamlessly

It is not uncommon for would-be curriculum reformers to decry the fact that our schools are organized in different disciplines, and thus different departments. This affects not only curriculum, but also hiring and in general a certain view of education that separates human endeavors into separate, disconnected “siloes”. Sometimes, this complaint leads to the creation… Continue reading Making Connections

On BlueSky, Bryan Meyer asks: Henri, in your experience, what are the pros and cons of using function diagrams with kids (in addition to the more standard Cartesian representation)? My BlueSky reply: "Cartesian graphs are a life tool. Function diagrams are a learning tool, so less crucial, though I have found a few activities at… Continue reading Function Diagrams
Asilomar Report 2024
I hadn’t planned on attending the Asilomar conference this year, as both my proposed presentations had been rejected. However I was on the waiting list, and was invited at the last minute, presumably because there was a cancellation. Once again, it was a smaller conference than pre-Covid, and I saw fewer familiar faces among the… Continue reading Asilomar Report 2024
Making Struggle Productive
At the start of the opening chapter of our new book (There Is No One Way to Teach Math), Robin Pemantle and I argue that teachers should learn to embrace contraries. The idea is that instead of choosing one or another option in a binary pedagogical choice, and instead of seeking a supposedly happy medium… Continue reading Making Struggle Productive
Proof in High School
Proof in Geometry Many years ago, when I was still teaching high school, I added a Teaching Proof page to my website, which included a bit of philosophizing and links to the relevant parts of the site. If you’re looking for ideas and materials on this topic, you should definitely check out that page. I’ve… Continue reading Proof in High School
