Election

I don’t know if I have the words in me right now to write about this thoughtfully and coherently, but I’ll try.

Staying up and watching the election returns Tuesday night into Wednesday morning was difficult. It was difficult for me, as a political leftist and radical, as a believer in social justice movements, as someone who cares deeply about issues of poverty and climate change (two topics barely touched upon in the media coverage of this campaign). In some ways, it hearkened back to the 2000 election, and feelings of outrage and disappointment I experienced then and thereafter during the Bush presidency.

But, although there are some comparisons to be made, in many ways this election result was much worse, at a whole new level. What has made it more difficult for me is thinking of my students, the hatred they see directed at them, and the fear they must feel. From words and actions of Trump himself, and also from the words and actions of his supporters at rallies. My black students, faced with a president-elect who courted and did not reject the support of the KKK and other white supremacist groups. My Latino students, called rapists and murderers by our president-elect. My Muslim students, who are told by Mr. Trump that their entire religion should be banned from entering the United States. My immigrant and refugee students, who feel unwelcome and fear deportation, due to many things said over the course of the campaign. My girls, who now face a president-elect who has evinced zero respect for women throughout the campaign and his career, and is famous for talking on tape about how he would/could sexually assault women.

Although I can imagine how it might feel for them, I do not actually know what it is like living in fear for one’s life or liberty or home that many of my students are probably feeling. Nor do I know the day-by-day degradation of being told your life doesn’t matter, that your rights don’t matter, that your body doesn’t have any rights that others are bound to respect. The fact that Trump has not only said all the horrible things he has said, but that he has encouraged violence from his supporters directed at non-supporters, and that he has normalized this kind of language, hatred, disrespect, and violent actions: this is what scares me most.

The Baltimore Sun interviewed students at my school on Wednesday, including one I teach, for an article on the election: “Immigrant communities fear deportation after election of Trump”

#teach180, part 1

As I mentioned in my New Year 2016 post, I am posting a photo most school days.

This year I am thinking I shall try to keep up with #teach180 on Twitter, posting a photo tweet every school day (more explanation here).

Some are photos of my students, others are photos of projects they are working on, others are screen captures of lessons or tools that I use, others are more random (a new art piece on the wall at my school that I really liked).

My goal is one photo (and caption) every day on twitter. I have already missed a few days, but here are my first two weeks:

  • Day 1, digital syllabus
  • Day 2, my classroom
  • Day 3, origami balloons in CIM
  • Day 5, map mosaic
  • Day 6, course homepage on LMS
  • Day 8, helping teachers build web pages
  • Day 9, students making music on Raspberry Pi

Happy teaching!

New Year

Greetings readers, and happy new (school) year! This is year number eleven for me (who knows where the time goes?).

This year I shall be teaching the following subjects:

  • Computer Integrated Manufacturing (my tenth year with this, my most-frequently-taught class) – Fall, two sections
  • Foundations of Computer Science – Spring (ninth graders, to be recruited)
  • Precalculus – Spring
  • AP Computer Science Principles (a brand new AP course this year, though it has been in the works and piloted for several years, including last year by me) – Full Year

Here’s the College Board’s Intro Video to the new CSP course:

I’m super-excited for the new year, and the new CSP course in particular (if you’d like to follow along with our daily agenda, it will be updated each day at http://www.tinyurl.com/PHSCSP ).

This year I am thinking I shall try to keep up with #teach180 on Twitter, posting a photo tweet every school day (more explanation here). We’ll see if I can keep that up, after my abysmal recent record of updating this blog. 🙂

I’ve also just started my fall course from Georgia Tech, Computer Vision. I’m very much looking forward to it, and learning how computers can make sense of what they “see”!

To all the other teachers out there, hope you have a great year!

Happy (Round-Up) Pi Day!

Greetings once again, one and all!

PiDay

Pi Pies (photo by djwtwo on Flickr)

It is PI DAY, y’all – gather round and roll out the red carpet for that most glorious of numbers,

3.14159265358979323846264338327950288419716939937510…,

a.k.a π,

a.k.a pi.

Irrational

In fact, though we made a big deal of last year’s celebration as the “Ultimate Pi Day”, or the “Pi Day of the Century”, a case can be made that today is even more special! Today’s date, 3/14/16, is a rounded-up version of pi to four decimal places (rather than a truncated version like last year); it also only comes around only once a century; and in fact 3.1416 is about nine times closer to the actual value of pi than 3.1415 is! 😉

If you’re a little bummed out that we won’t have a “pi day of the century” next year (after all, 3.1417 doesn’t seem too special), check out this article (via MAA) which proves that, for some norm other than the Euclidean distance, there is a “pi” for that norm that will match that year–thus every pi day can be the “pi day of the century”!
