Yellow

The Lindheimer Senna has started focusing on seed pods. The yellow blossoms, after having added reliable yellow color to the yard throughout the blistering days of Central Texas summer, are now gone. But they are certain to return next year.

As summer begins to think about winding down, I’ve stopped dead-heading the Cowpen Daisies. The front yard is still full of their yellowness, but gradually those blossoms are going to seed in such profusion that there will be plenty to collect and share and plant along the Chemistry Wing at the high school.

This year, we’ve had success with the Esperanza/Yellow Bells on the (scorchingly hot) south side of the house. We’ve left a slow drip hose on them when watering elsewhere in the yard on our weekly watering day, and yellow bells have reliably hung from the plant for most of the summer despite the mauling they took from the construction crew installing the new siding.

And we come now to the star of the early fall — Golden Eye. Ever since Bill down the street brought us some bare-root plants many years ago, these shockingly hardy natives have reliably pushed out a profusion of yellow every October. They grown to about six feet tall in places, and to get to the outside faucet these days, you must push your way thru a thicket of them, with bees buzzing all around.

There are Bees

As the temperatures moderate, it’s possible to actually sit outside. Sit outside and enjoy cool morning and evening breezes. Sit outside and enjoy the profusion of yellow and orange and purple in the yard. And enjoy the bees who especially enjoy the profusion. 

The bees are impossible to catch in a photo. They buzz quickly from blossom to blossom and then fly off to parts unknown before the camera will cooperate.

But the flowers with their yellow and orange and purple blossoms are more accommodating.

It was the end of the day. A four-day weekend lay before us. We were all in a good mood.

The bell rang. Most of the kids quickly filed out. A few lingered to avoid the crush at the door and leisurely pack their bags.

“Mr. Hasan,” she said, walking up to me.

“Yes?”

“I was selected to be Boromir.”

She explained how she had applied and was selected for a Lord of the Rings event later this fall. She had a broad smile on her face as she spoke. She knew I would understand. 

“That’s amazing!” I said. “Congratulations.” 

“I’m keeping my Silmarillion and Return of the King Appendix A with me everywhere I go.”

This morning I doodled this and sent it to her. Some of you might understand. Some maybe not.

No Phones Down Day

We had a short day last week. Not enough time for a full lesson, and several periods had just come off a legit hard test.

I put this up on the monitor at the front of the class.

“What’s that?” someone asked when they came into the room, pointing in genuine perplexity at the cryptic (?) glyph.

“It’s our plan for the period,” I said. There was an almost-audible sign in the room.

Of course that wasn’t quite true. (Of course it wasn’t.) There were kids who worked on test corrections. There were kids who worked on missing assignments. There were kids studying for other classes.

But there were no phones (as is the case every day this year, now that the legislature has our back on at least that issue).

Make Cancer Great Again

1. Background

Years ago after I returned to work following surgery and lymphangiograms and more surgery and radiation therapy and chemotherapy for cancer, a colleague sat with me at lunch.

“You know, chemotherapy isn’t natural,” he said.

There just wasn’t much further that conversation could have gone. It was clear what he was implying — I was corrupting the gene pool.

Fast forward to today, and we have billionaire tech bro masters-of-the-universe breathing new life into eugenics.

2. Canceling Cancer Funding

I claim that bro-rebranded eugenics is hard at work. For example, Google around a bit. You’ll find articles about the Trump administrations cuts to cancer funding.

Admittedly, the story is a bit more complex than sensationalist headlines let on (link: snopes), but there is a reality on the ground that makes the full truth of the matter misleading — funds were just temporarily delayed and meetings temporarily suspended. Yet temporary or not, the actions have had consequences. Clinical trials got canceled in the temporary absence of dollars to pay salaries. Fundamental research projects got shut down in the temporary absence of approvals from review boards who are forbidden from collaborating with researchers.

Some cancer work was canceled.

You can’t manage what you don’t measure.

Don’t like public policies that address food insecurity? Then just stop measuring food insecurity.

1. Read the Instructions

I walked over to their desk when they raised their hands.

“Mr. Hasan,” one of them asked, “can we just write our work for problems 2 and 3 over here?” They pointed to the right of problem 1.

“No,” I said.

“What!? We can write small!”

“Did you read the instructions?”

They had guilty looks on their faces.

“For shame,” I joked. “Read the first two sentences out loud.”

They looked at the top of the paper and started to read out loud.

I have not left you any room on this sheet for your work on problems 2 and 3. To get credit for this assignment, you must do all your work for those problems on separate sheets of paper, closely following the steps we did in the notes.

“Oh,” they said.

2. Why Would I Do this?

You might ask why I do this. Am I just mean-spirited? After all, if they can write their work anywhere, doesn’t that demonstrate mastery of the core underlying skill?

Well, that is sufficient only if you have an incomplete notion of what the core underlying skills really are. There are in fact two.

You see, what I’m doing in this lesson is preparing them for the next. Tomorrow, the problems will be more confusing and the technical steps involve many more details than today. If they squeeze their work into an arbitrary block of white space they’ll “lose lock” on what the heck they’re supposed to be doing.

In tomorrow’s problems, being organized will be a necessary precondition for getting the math right. Without that, the whole process will be a dizzying blur. (I know this from personal experience as a student many years ago.)

So no, I do not do this to be mean. I am intentionally teaching (1) organizational skills and (2) mathematical skills together to prepare them for what’s next.

Because without mastering both, they’ll be toast on the next test.

Words Matter

1. Ambiguity

In the abstract it’s a fair question. Does this mathematical notation

(2,7)

represent a point in the x-y plane with coordinates x=2 and y=7? Or does it represent an interval on the number line extending from x=2 to x=7?

The  notation by itself really is ambiguous.

2. Clarification

When he called me over, he pointed to his laptop screen. 

“I’m not sure about this question,” he said. “Are these points or intervals?”

“Well,” I said. “Read the question carefully.” And I pointed to the sentence:

Consider the two points, (2,7) and (5,10), ...

“Oh,” he said.

No ambiguity!

3. Close Reading

Of all the challenges in teaching AP Precalculus, I find this the greatest: The kids do not “read” the questions. Their attention snaps to the math-y stuff, and they immediately begin answering, often before they know what the question is.

This is a recipe for disaster on the AP Precalculus test, and they’re not used to it. The AP test is loaded with questions where it is absolutely crucial that they slow down (and maybe set down their pencils?) and read every single word as if their success depended on it. 

And so my mission in this class is to teach the kids to read closely, just as much as teaching them them the (challenging) mathematics.

Because on this test, words matter.

Conspiring Against Us

The poor man. Not invited to the party with its fancy festivities and marching military parades. Unable to hobnob with his besties, Xi, Vladimir, and Kim. He whines that they are conspiring against us.

Conspiring. You think!?
