Who Needs Math? A Student Responds

For a political science professor, Andrew Hacker is surprisingly familiar to math teachers.  His 2012 New York Times Op-Ed “Is Algebra Necessary?” generated lots of conversation in the math education community, including several pieces from me:  “N Ways to Use Algebra With the New York Times” in NYT Learning, and “Replace Algebra with Algebra?”.

Professor Hacker is back in 2016 promoting a new book, and in a recent NYT interview he revives his anti-math arguments from four years ago:  math is not really necessary for jobs; it’s too hard; it prevents students from graduating.

I saw the piece and didn’t feel the need to respond.  There was nothing new, and I’d said what I wanted to say here.

But I was pleasantly surprised when I saw this letter-to-the-editor, written by a high school student, published in the February 19th edition of the New York Times.

In “Who Needs Math? Not Everybody” (Education Life, Feb. 7), Andrew Hacker, who teaches quantitative reasoning at Queens College, says that since only 5 percent of people use algebra and/or geometry in their jobs, students don’t need to learn these subjects.

As a high school student, I strongly disagree.

The point of learning is to understand the world. If the only point of learning is job preparation, why should students learn history, or read Shakespeare?

And while your job may never require you to know the difference between a postulate and a theorem, it will almost certainly require other math-based skills, like how to prove something or how to understand a graph.  

And my surprise turned to delight when I realized that the author is a 9th grader in my Geometry class!

While her love of mathematics and her wonderful attitude toward learning certainly predate my Geometry course, I am very proud to see reflections of our classroom in her letter.

TCM at NCSSM

falling pebbles 3I’m excited to be presenting at the upcoming Teaching Contemporary Mathematics (TCM) conference at the North Carolina School of Science and Mathematics (NCSSM).

NCSSM is an internationally known leader in providing advanced math, science, and engineering education to public school students.  They have a residential program that serves 11th and 12th graders and distance programs that serve students all across the state of North Carolina.

NCSSM hosts the annual TCM conference to bring together teachers to talk about innovations in teaching modeling, technology, and problem-solving in advanced high school courses.  My talk, Mathematical Simulation in Scratch, details some of the work I and my students have done in our mathematical computing course.

TCM runs January 29-30 on the campus of NCSSM in Durham, North Carolina.  You can find out more information about the TCM conference and see the schedule of talks here.

2015 — Year in Review

I always enjoy taking time at the end of the year to review my blog. It’s a great way to reflect on what I did and what I was thinking about, and it always reminds me how busy the year was! And 2015 was definitely a busy year.

The Presidential Award

awards_PAEMSTWithout a doubt, the highlight of my professional year was being named a recipient of the Presidential Award for Excellence in Mathematics and Science Teaching (PAEMST).

I traveled to Washington, DC with other awardees to meet with representatives of the National Science Foundation, the National Academies of Science, and the Office of Science and Technology Policy. And the highlight of trip was meeting President Obama at the White House!

The trip to DC was part of an active professional summer.  I presented my paper “Monte Carlo Art” at this year’s Bridges Math and Art conference, and the following week I ran a fun workshop called “Games on Graphs” at the MOVES conference at the Museum of Mathematics. At the end of a very busy few weeks, I was surprised to find myself in this terrific New Yorker piece, “Cogito, Ergo, Summer” by Siobhan Roberts!

Speaking

In addition to presenting at Bridges and MOVES this summer, I traveled to Washington, DC earlier this year to speak at a policy briefing hosted by the Mathematical Sciences Research Institute (MSRI) during the first ever National Math Festival. I spoke about building the profession of math teachers, and was a bit intimidated to follow Nancy Pelosi, Harry Reid, and Al Franken! I also ran a variety of workshops on math and technology for teachers, and hosted Math for America’s 4th annual Master Teachers on Teaching, a great evening of talks from MfA Master Teachers.

Teaching

I always try to do new things in my classroom and my school, and 2015 was no exception. I’ve been having fun playing around with 3D-printing in a variety of classes, building demonstrations for geometric ideas, printing hard-to-imagine surfaces, and getting students creating with mathematics. I continue to develop and teach an integrated mathematics and computer science course, and I have taken on a part-time role as our department’s instructional coach.

Writing

For a variety of reasons I write less frequently than I used to, but I did surpass 1,000 total blog posts this past year! My work critiquing the New York State Regents exams continues to get attention,  and I was informally consulted for an excellent report by the Center for New York City Affairs about the serious issues facing New York state’s algebra exams that eventually caught the attention of the New York Times. And I continued my work with the New York Times Learning Network, contributing math lessons on evaluating compulsory retirement savings plans and asking students “Why Do Americans Stink at Math?”

So a great year comes to an end, but here’s hoping 2016 is just as challenging, productive, and rewarding!

MT^2 2015

pih mt^2 2014 3-001I am excited to be hosting Math for America’s Master Teachers on Teaching (MT^2) event this December 10th  at the Gerald D. Fischbaum auditorium.

MT^2 is an evening of short talks from MfA Master Teachers that are meant to inspire and challenge the MfA community.  And it is a showcase of the passion and talent of that community, which now numbers nearly 1,000 teachers of math and science in New York City.

This will be the 4th annual MT^2, and the theme is Equality / Inequality.  The evening’s lineup features eight talks from middle and high school math and science teachers offering a variety of different interpretations on the theme.

I have given talks in each of the first three MT^2’s:  first, on the bad habits students learn from standardized tests; then on my relationship with change; and last year, about how to turn technology’s failures into teachable moments.  While I enjoy the challenge of presenting, I am honored to be hosting this year’s event, and I look forward to an evening of great ideas.

And Math for America hopes to live-stream the event, so stay tuned!

Regents Recap — January 2015: Gravity on the Moon

Here is another installment in my series reviewing the NY State Regents exams in mathematics.

There is something of a history with Regents exams and the force of gravity.

An infamous problem years ago modeled a falling object with the quadratic function

y = 2x^2 -12x + 10.

This would imply that the acceleration due to gravity, or g, would be equal to 4 f/s², not the -32 f/s² we are accustomed to.  This amusing error inspired my talk “g = 4, and Other Lies the Test Told Me“.

So, it was interesting to see projectile motion appear twice in the most recent round of math Regents exams.   This is from the Integrated Algebra exam.January 2015 IA 24

I was pleasantly surprised to see the proper coefficient!

And then I noticed a second appearance of gravity.  This is from the Common Core Algebra exam.

January 2015 CC A 21

Of course, I had to check.  Kudos to the exam writers for looking up the actual force of gravity on the moon.  If we’re going to go to the trouble of trying to establish “real world” contexts for these problems, we should make sure physical forces are accurately represented.
