Connected Educator Month

As part of Connected Educator Month, I contributed to the New York Times Learning Network’s “What Connected Education Looks Like”, a collection of viewpoints on what being connected means to teachers in this day and age.

Here’s my piece, which was inspired by two mathematicians on Google+ who inspired me to create a Linear Algebra course at my school this year.

I’m teaching Linear Algebra at my high school this year, and social media is to blame.

Two mathematicians I’m connected to on Google+, Theron Hitchman andVincent Knight, regularly post engaging pieces about mathematics, teaching and technology. Theron’s enthusiasm and insight and Vince’s cool applications to operations research rekindled my interest in Linear Algebra. So when discussing what electives to offer our mathematics majors at Brooklyn Tech, I volunteered to create a Linear Algebra course.

As usual, I’m in over my head, but Theron and Vince are there to help, sharing their views on the big ideas in Linear Algebra, using technology to docool things with matrices and pointing me to resources like free e-books and open-source mathematical software. I probably wouldn’t have taken on this challenge without my connections to these mathematicians, but being connected to them and others will help make it work for me and my students.

2013 PAEMST Finalist

[UPDATE: I was awarded the PAEMST!  Read about it here.]

I am proud and excited to announce that I am a finalist for the Presidential Award for Excellence in Mathematics and Science Teaching (PAEMST)!

The PAEMST is a national award given annually to at most two teachers from each state in the US.  The awards alternate each year between K-6 teachers and 7-12 teachers.

I have been named a finalist for New York state, along with three other mathematics teachers.  Decisions at the national level will be made later this year, and the award carries with it a Presidential Certificate and a trip to Washington, D.C. for meetings and professional development.

It is a great honor to be named a finalist.  The application process was intense and comprehensive, but it was a worthy professional experience, and I’m glad that the selection panel saw the value in my work.  I also know two of the other finalists from New York and have great respect for them, so I know our state will be well-represented.

Regents Recap — June 2013: Writing ‘Engaging’ Questions

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

An all-too-common pastime among math teachers is laughing at the absurd, contrived contexts employed by textbook and exam writers to make problems real-world and engaging.  Here are two examples from the June 2013 New York math Regents exams.

2013 June A2T 37Years ago, thinking of the triangle as a garden or corral was enough to make finding its area sufficiently real-world.  But I guess now it needs to be kicked-up a notch, say, by taking it to the Australian Outback!

Here’s another classic example.

2013 June IA 24You know what really gets students engaged in math problems?  The word RAP.  The best part is that the set A isn’t even used in the question.

Where are the Good Conversations?

In October, I will be running a workshop through Math for America titled “Professional Development Through Social Media”.  The goal of this two-hour workshop is to provide an overview of the opportunities for professional growth, collaboration, and reflection that teachers can find on various social networks.

As part of the workshop, participants will be invited to peruse interactions–posts, comments, exchanges, conversations–that highlight the nature and strengths of the various digital professional communities.  I have a number of good starting points in mind, but I’d love to have more.

I invite you to leave a suggestion in the comments.  Provide a link to something great and give a brief description of what this highlights about the online professional world.  The workshop will include both math and science teachers, so links to non-math resources are definitely welcome.  And please feel free to suggest your own work!

Thanks in advance for your help.  Assuming this is successful, this post itself will become an example of the value of being connected!

Rosenthal Prize Lesson — Sphere Dressing

sphere dressing imageThe Museum of Mathematics has posted my Rosenthal Prize lesson, Sphere Dressing,  on their website and made it freely available for download.

In this lesson, students explore the connections between plane and solid geometry by designing and building hats to cover a sphere.  This set of activities, which includes options for grades 4 to 12, was part of my application portfolio for the 2012 Rosenthal Prize for Innovation in Teaching Mathematics , and I was honored to be named runner-up.  A nice profile of the two winners appears in Scientific American here.

You can download my lesson, Sphere Dressing, here.  You can find out more information about the Rosenthal Prize, and find more award-winning lessons for download here.
