Mistakes made this year

There have been many times this past year when I have wished I could go back and correct or redo something. I can really appreciate the struggles that new teachers face. There are an overwhelming number of new things to consider and so there are bound to be things overlooked or mistakes made. At my usual university job, when I think of something to fix or do better the next time I teach a course, I jot down notes to myself and I read those notes before teaching the course the next time.

This time, it’s unlikely that I’ll get to teach Algebra 1, Geometry or Algebra 2 to high school students any time soon. However, I’ll still write down my thoughts anyway.

One of the biggest mistakes that I made is that I didn’t plan in larger instructional units. My lesson plans tend to be conceived from week to week, day to day. My teaching this year lacks a larger architectural design and I’m sure this manifests itself in students who don’t see the forest for the trees. I haven’t been doing much foreshadowing (preview of coming attractions) in my teaching and so there are fewer connections between topics. I also did not realize the extent to which district, state or school tests impose themselves on my instructional choices; so many times I scrambled to “cover” something before a test instead of allowing the tests to do what they are meant to do–to assess students’ understanding of topics that they have already had the chance to master in my class.

I am a big fan of “backwards course design” (espoused by James McTighe and Grant Wiggins in Understanding by Design) and have even led professional development sessions about this kind of instructional design. But have I done much of it this year? No. I feel like such a hypocrite.

Fire alarm

During the last period of school today, the fire alarm went off. This is a terrible thing, but all of us at this school have gotten so jaded by false alarms that we didn’t move for a while until someone PA system that it was a real alarm and that we needed to evacuate. We made our way to the field where we hung out for a while, then returned to class. More wasted instructional time, oh joy. It turned out two students set two separate fires at the same time in two bathrooms, so it wasn’t a drill or someone pulling the alarm for kicks.

I am looking forward to the four day weekend that has been made possible by furlough days in our district. Wheeee!!

Kids say the darndest things

While I was sick last week and out of school, my colleague got my students to write me get well cards and thank you notes. It was super awesome gesture on her part and my students wrote some really nice things.

This one really got to me, mostly because for a long time I wasn’t sure if I was really reaching this student or not. He doesn’t speak much English and he sits by himself off to the side of my Algebra 1 class. This student is in the United States illegally and he’s afraid of getting deported. He understands English better than he can speak it, but sometimes I have to use Google translate to communicate with him. I love that he only knows me as “Mister Jhon” (not my real name, obviously).

One thing I’ve learned about teaching high school: the low points can be so low, but the high points are correspondingly high too.

Was innumeracy a factor in the recent housing bust?

Here’s an interesting research article that I found by way of this article in the Economist: “The Fear of All Sums” (May 13, 2010). The authors of the paper found a strong correlation between individuals with poor math literacy and individuals who were delinquent on their loans in the recent housing bust, and this result was robust even when controlling for age, ethnicity, level of income, FICO score, highest level of education, and other sociodemographic variables. Furthermore, the authors of this study found that people with poor math literacy were not more or less prone to enter into subprime mortgages than people with high math literacy. The reason suggested by the authors for the difference in mortgage delinquency is that people with poor math literacy are not as good at managing their daily finances.

Here are the five questions that they used to measure math literacy:

  1. In a sale, a shop is selling all items at half price. Before the sale, a sofa costs $300. How much will it cost in the sale?
  2. If the chance of getting a disease is 10 per cent, how many people out of 1,000 would be expected to get the disease?
  3. A second hand car dealer is selling a car for $6,000. This is two-thirds of what it cost new. How much did the car cost new?
  4. If 5 people all have the winning numbers in the lottery and the prize is $2 million, how much will each of them get?
  5. Let’s say you have $200 in a savings account. The account earns ten per cent interest per year. How much will you have in the account at the end of two years?

I’m curious to see how my students will do on these questions. I feel a sense of personal responsibility that even if students aren’t going to learn Algebra 1, Geometry or Algebra 2, that I try to help them raise their basic math literacy skills.

I like Open House Night

Last night we had an Open House night where parents could visit their students’ classrooms and talk to their teachers.

I’ve been to two of these now and I like coming to these things. For one thing, not many parents show up, so it’s a good time to tidy up around the room and get stuff done.

Open House night is also good for my ego. At our school, it tends to be the involved parents who come to these events and there is a high correlation between involved parents and students who are doing well. These parents say nice things–it’s nice to feel appreciated. One parent told me “You’re a beautiful person.” Another told me I’m a talented teacher. I hope this fuel will last me until the end of the year.

If I pull a Steve Poizner…

I heard a fascinating story today about Steve Poizner, his teaching stint and subsequent book, on my favorite radio show, This America Life. Before you continue reading, I urge you to go listen (it’s the first act of the show). It will be a half hour well spent, I promise.

. . . . . . . . . . . (30 minute break while you go listen to the show) . . . . . . . . . . .

OK, in case you didn’t go listen <a href=”insert guilt trip here”>, here’s a brief summary. Steve Poizner, high tech entrepreneur, hella-millionaire, conservative candidate for California governor this year, taught a U.S. Government class for one semester at Mount Pleasant High School in San Jose in 2002. His book, “Mount Pleasant: My Journey From Creating a Billion-Dollar Company to Teaching at a Struggling Public High School,” published this year, has met with some resistance from those who say he has mischaracterized the school and its neighborhood as a “rough-and-tumble.”

Let me first say clearly that I have not read Steve Poizner’s book, but I will try to rectify that soon. Whether Steve Poizner intentionally inflated facts to sensationalize his book is not clear–he does sound very genuine during his interview with Ira Glass. My initial reaction is that (1) it’s a case of confirmation bias, and (2) it’s very tempting to bend facts for more dramatic story telling.

Confirmation bias is the tendency that people (including me) have to assimilate evidence that confirms what they already believe, even if that evidence is inconsistent, from a source with poor authority, or just plain false. Steve Poizner argues in favor of charter schools in this book and he co-founded the California Charter Schools Association in 2003 (just after his teaching stint), so it seems to me that he would naturally favor evidence suggesting that our public schools are failing and irreparable, since that is one of the tenets of the charter school movement.

But whether Steve Poizner intentionally cherry-picked statistics and exaggerated to sensationalize or not, I can really relate to that temptation to sensationalize while writing this blog. The vast majority of you reading this blog do not know where I’m teaching and I’ve often felt tempted to bend the facts, or at least dwell on the negative aspects of my school, so as to make for more drama. If I am guilty of “pulling a Steve Poizner,” I hope you, my friends, will call me on it. At least you can rest assured that I am neither a millionaire, nor am I going to run for governor anytime soon.

Here’s what I found most disturbing about Ira Glass’s story:

“[Glass speaking]…the conclusion Poizner comes to–again and again during these scenes–isn’t that he’s doing anything wrong or has anything to learn as a teacher. Instead, he blames the kids. They’re tough, they’re unmotivated, they lack ambition, they’re wired differently.”

Hmmm…  If that’s true, that’s a bad thing. It’s a teacher’s job to try to motivate students, and teachers (dare I say, even politicians) must be life-long learners. I’m a first-year high-school teacher and I run up against my failings as a new teacher every day. I could do a much better job caring about students, designing lessons and materials that will motivate them, being patient with them. After one year of teaching, I have a better idea of what it is to teach high school mathematics in Los Angeles, but there is still so much more I need to learn about teaching.

Final shout-out: Many thanks to DM for a helpful chat about confirmation bias!
