Practical Alternative to “Algebra for All”?

Anyone who has read my blog probably already knows my feelings about high-stakes tests.  In a nutshell, I think the tests do more harm than good.  I think the tests are emphasizing the wrong skills, and I think we’re teaching the wrong skills in order to “help” students be “successful”.

Long before “No Child Left Behind,” there were two pathways for high school students to study mathematics.  One was the algebra-geometry-trigonometry-calculus pathway, which served students who intended to go to college and pursue subjects that required higher math, such as science, and engineering.  The other was the “business math” pathway, which served students who intended to forego college and go straight into the business world, as well as students who intended to go to college to pursue non-mathematical disciplines.

Teacher Crushes

Teacher crushes are a common occurrence.  Even if you’ve never had one yourself, you don’t have to ask many people before you find someone who has had a crush on a teacher.  And yet, it’s a subject that almost everyone is afraid to talk about.

Gratitude

All of my students (except for two juniors) at Lynn English High School graduated today.  Of course I’m proud of them.  But more than that, I’m happy for them—happy for the doors that have opened for them and all the opportunities that are waiting to be discovered.  And even more than that, I’m thankful that I got to spend a year with them, teaching them and helping them deal with adolescent life.

But most of all, I’m thankful for their gratitude.  In schools I’ve taught in before, I’ve had students tell me that they enjoyed my class and that they thought I was a good teacher.  But this year is the first time I’ve really felt deep down that a significant number of my students were truly grateful.  Grateful for the academic and emotional support and confidence-building that I always endeavor to give my students, because everyone should have these things.  These were freely given, so it never occurred to me that anyone ought to express gratitude, and that makes it all the sweeter because so many of them did.

Thank you, LEHS class of 2012, for the best year of my teaching career to date.  May life be as good to you as you have been to me!

Request to Math Teachers: Teach Graphical Solutions

The instructions seemed adequate:  plot your data, draw a best-fit line, and extrapolate the line to find the y-intercept.  Graph paper and rulers were available on a table at the front of the classroom.  To me, the implication was crystal clear that the graph should be done accurately on graph paper, and the line placed carefully and drawn using a straightedge.  Evidently, this is only clear to students who learned math during the pencil-and-paper era.

Diet Coke & Mentos Final Exam: Physics Version

I gave a chemistry final exam involving Diet CokeTM & MentosTM back in 2006.  I’ve done it as a lab experiment a couple of times since then, but not as a final—until this year, when I did a physics version.

Treating Students With Compassion

Several friends on Facebook have asked me to comment on the article entitled Lincoln High School in Walla Walla, WA, tries new approach to school discipline — suspensions drop 85%.  What the article describes is more or less exactly how I treat my students, and more or less exactly for the reasons given in the article.

Tough Love vs. “Tough Shit!”

The lesson from “tough love” teachers is that if you don’t do the work, you can’t master the subject and you fail.  Most kids have already learned how to fail.  What they need to learn is how not to.

Pushing the Reset Button

On Friday, while I had cafeteria duty, I noticed a girl with a bruise on her face.  I asked her what had happened.  She said with a sheepish half-smile, “I got into a fight.  But don’t worry.  It wasn’t on school grounds and no one videotaped it.”
