Book Review: The Proof in the Code, by Kevin Hartnett

Math is changing, and more change is on the way. Kevin Hartnett's new book "The Proof in the Code" is a great entry point to the world of AI-assisted mathematics, especially for teachers and learners of mathematics.

An OpenAI model has disproved a longstanding conjecture regarding what's known as the Unit Distance problem. Says Fields Medalist Sir Timothy Gowers: "This will I think be looked back on as the first time that AI solved a major mathematics problem."

An OpenAI model has disproved a central conjecture in discrete geometry

An OpenAI model solved the 80-year-old unit distance problem, disproving a major conjecture in discrete geometry and marking a milestone in AI-driven mathematics.

Excited to share my new article investigating the STEM pipeline for students with and without disabilities published open access in Research in Higher Education. High school math taking was a key factor! #StudentswithDisabilities #HigherEd #K12Ed #MathEd

Students with Disabilities Pursuing STEM: High School Math Preparation to Postsecondary Degree - Research in Higher Education

This study examines variations between students with and without disabilities as they progress from high school mathematics to a STEM college major and STEM degree. Analyzing data from the Education Longitudinal Study with multinomial logistic regression found 10th graders with disabilities take less advanced high school math than students without disabilities, creating a disparity that persists through college. This places what might otherwise seem equivalent STEM college opportunity into an already unequal context. This disparity underlying the STEM college pipeline means enhancing STEM career access for individuals with disabilities ought to begin in high school or earlier.

San Francisco stopped offering Algebra 1 in middle school a decade ago. "The number of students enrolled in advanced high school math declined". Shocking! Now the pendulum swings back.

Of course the high-profile people who supported this will never admit that this was a ridiculous idea to begin with. They'll just say it just wasn't implemented properly. And they'll move on to the next big thing in education.

San Francisco Killed 8th-Grade Algebra. Now It’s Set to Come Back.

The San Francisco school board approved a plan to restore algebra as an option at all middle schools, more than a decade after it was removed over equity concerns.

The Aftermath of DrawEduMath: Vision Language Models Underperform with Struggling Students and Misdiagnose Errors

Effective mathematics education requires identifying and responding to students' mistakes. For AI to support pedagogical applications, models must perform well across different levels of student proficiency. Our work provides an extensive, year-long snapshot of how 11 vision-language models (VLMs) perform on DrawEduMath, a QA benchmark involving real students' handwritten, hand-drawn responses to math problems. We find that models' weaknesses concentrate on a core component of math education: student error. All evaluated VLMs underperform when describing work from students who require more pedagogical help, and across all QA, they struggle the most on questions related to assessing student error. Thus, while VLMs may be optimized to be math problem solving experts, our results suggest that they require alternative development incentives to adequately support educational use cases.
