The Bamboo Ceiling

7 Jun 2015 /

Michael Wang had a 4.67 GPA and a perfect ACT score. He placed first in the state of California at the AMC 12 – a nationwide mathematics competition. He performed with the San Francisco opera company, and sang in a choir that performed at Barack Obama’s first inauguration. He volunteered his free time to tutor underprivileged children.

He applied to seven Ivy League schools and was rejected by all seven.

I saw recently that a local kid from Fullerton High School here in Orange County was accepted at all eight Ivy League Schools. His name is Fernando Rojas.

Here’s another young man, Harold Ekeh, who was also accepted at all eight Ivy League schools:

Last year, Kwasi Enin was accepted at all eight Ivy League schools:

A study by Princeton sociologist Thomas Espenshade examined applicants to top colleges from 1997, when the maximum SAT score was 1600 (today it’s 2400). Espenshade found that Asian-Americans needed a 1550 SAT to have an equal chance of getting into an elite college as white students with a 1410 or black students with an 1100. I suspect that disparity has, if anything, widened.

If you’re Asian and applying to Ivy League schools, don’t hesitate to check the box next to “Black” or “Hispanic.” Or Eskimo. Eskimos are kind of Asian-looking.


If Math Was Taught Like Science

Now What?

We’re in Berkeley for Casey’s graduation tomorrow . . . we got a text from him earlier this week saying “I just took my last two college exams.” Thus ends a journey that began 17 years ago on the first day of kindergarten, which I feel like I remember too vividly for it to have been 17 years ago, but it was.

Now what? I don’t mean for him . . . he’s got a job lined up in San Francisco. I mean for me. I’ve had the milestone birthdays — the ones where your age ends in zero — that seem to depress a lot of people . . . they didn’t bother me at all. But my boy becoming an independent person in the world is really disorienting me . . .


Teaching Computer Science: Ask More Questions

20 Apr 2015 /

You need to ask more questions. I think there’s a general fear about asking questions. There’s a risk of looking foolish in front of the whole group when it turns out that everyone else already knows the answer.

It’s actually very unusual for someone to ask a question to which everyone else knows the answer. If you find it happens to you a lot, you probably want to get that checked out, but normally it’s very unusual.

Another scenario: Somebody, maybe a teacher, says something and you think “That doesn’t make sense. I wonder if it makes sense to everyone else. Rather than risk looking foolish in front of the whole group, I’ll wait and see if someone else asks a question.”

So you wait for someone to ask a question and no one asks a question. Why? Because they’re all waiting for someone to ask a question.

Many people, including teachers, are not good at organizing their thoughts and articulating them with precision and that’s why you can’t understand what they’re saying. Don’t assume that it’s a problem with you. You need to move people to a position of clarity by asking questions.

Also, people love the person who’s willing to ask questions because it relieves them of the need to ask questions.

Education, like everything else, you get out of it what you put into it. Don’t sit in a class with unanswered questions in your head and let everything wash over you like a tidal wave.

My own kid, even in a good school district, I don’t feel like he got a good education because of good teachers, I feel like he got a good education in spite of bad teachers. He got a good education because he put a lot into it and he got a lot out of it. And his classmates who got a good education did so because they put a lot into it and they got a lot out of it.

All of which is a long way of saying “ask more questions.”

Any questions?


Teaching Computer Science: Combating Procrastination

6 Apr 2015 /

Students had a project due last week and I got a lot of messages and emails asking for help. Of course, when we handed out the assignment two months ago, we advised students not to wait till the last minute to work on it. Teachers and parents saying “Don’t wait till the last minute” is just an understood part of the process. It’s something that gets said but it’s background noise.

A couple of alternatives occur to me:

  1. Reverse psychology. Say “My advice is to start as late as possible. Try to do two months of work in the last week, or better yet, the last night.” This seems too easy to see through and therefore unlikely to work.
  2. Hand out the 20-page spec and tell the students that it’s due tomorrow. WHAT!? YOU CANNOT BE SERIOUS! NOBODY COULD DO THIS IN ONE DAY! “You’re right. It’s actually due in two months. But now that we’ve agreed that it can’t be done in one day, I don’t want to see anyone working on it at the last minute.”

Teaching Computer Science: The Last Minute

“Reminder that your projects are due tomorrow so don’t wait till the last minute. Oh wait, this is the last minute.”

Deadlines can be fun when they apply to other people . . .


Teaching Computer Science: Incentives (or Lack Thereof)

22 Mar 2015 /

According to this article on TechCrunch, “Every California high school must establish computer science courses as part of its core curriculum.” From the same article: “Most California teachers have little or no training to teach computer science.”

Do you see the problem there?

I’ve been a programmer for many years . . . I’d be glad to teach computer science to students, teachers or anyone who wants to learn it if there were even a modest incentive to do so. Which there isn’t.

One way to measure how much people want something is how much they’re willing to pay for it. There’s no shortage of people talking about teaching programming and computer science, which is free (the talking, that is), but without the incentives ($$$) very little is going to actually happen.


Big Fishes in Small Ponds

Big fish, small pond

A colleague and I are discussing an article about too many kids quitting science because they don’t think they’re smart, in which Carol Dweck, a psychologist at Stanford, says, among other things:

Being a good parent has become synonymous with giving out ability praise. Parents still think this is the greatest gift they can give to their children, and as a child gets more and more insecure, they give more and more of it. And, by the way, a lot of employers and coaches have said, “My employees cannot get through the day without accolades and validation.” Even professional coaches have said they cannot give feedback without these people feeling that they’ve crushed them. We’ve created several generations now of very fragile individuals because they’ve been praised and hyped. And feel that anything but praise is devastating.

My colleague mentions Malcolm Gladwell‘s book David and Goliath, in which Gladwell claims that while the worst STEM students at, say, Harvard may be as smart as the top third at a lower ranked college, the Harvard kids feel stupid and unsuccessful because they compare themselves to their Harvard peers. Gladwell then goes on to recommend attending non-elite institutions — to be a big fish in a small pond — in order not to have your dreams and confidence crushed.

“Why don’t kids just forget about four-year institutions completely and attend their local community college?” I reply. “They can test their mettle against classmates with no academic qualifications whatsoever. That should provide a much-needed confidence boost.”


Teaching Computer Science: Pro Tips for Finishing a Project

5 Mar 2015 /

  1. For many (most?) students doing an object-oriented development project for the first time, this assignment is too difficult to do without a lot of guidance. Therefore: ask for help early and often.
  2. If you wait till the night before a checkpoint, you won’t have enough time to finish and we won’t have enough time to help you effectively. Therefore: ask for help early and often.
  3. I’m seeing students struggling to write code that we’ve already given you. That’s not a good use of your time. Know what we’ve given you and use it.
  4. This is what your program needs to do: [Feature list goes here].
  5. Pick a feature and try to implement it (or part of it). If you can’t do it, come to class tomorrow and ask a question.
  6. Repeat Step 5 until done.

Teaching Computer Science: Ski Week

3 Mar 2015 /

Skier

Corona del Mar High School doesn’t just take Presidents Day off . . . they take the whole week off and call it Ski Week.

It’s a total non sequitur in terms of paying tribute to our nation’s greatest leaders. George Washington didn’t ski. Abraham Lincoln didn’t ski.

“How do you know Abraham Lincoln didn’t ski?” a student asks.

“He was too busy writing the Gettysburg Address.”

“He wrote that in 20 minutes.”

“There was the whole Civil War thing going on. He didn’t have time for ski trips with his buddies.”

It’s hard to think of a notable historical figure who also a skier. If you want to accomplish great deeds, you have to give things up. You can’t get bogged down in nonsense.

Teaching Computer Science: Today Was Not the Best Day to Say What You Just Said

14 Jan 2015 /

Class website

I asked the class to pass in today’s homework and a student said, “I couldn’t figure out what homework was due today.”

I wasn’t feeling at my best to begin with. I was tired because I was up late making sure the class website was updated with all relevant materials, homework assignments were listed at the top of the page under the Homework header with due dates listed in bold font next to each assignment so that there’s no way anyone looking at the website, assuming they’re old enough to read, could fail to understand what is the homework and when is it due.

So when that kid said that he couldn’t figure out what the homework was, I felt the futility of life grabbing me by the throat and I was mad . . .


The Public School Monopoly Provides Little Incentive to Supply Good Education

31 Dec 2014 /

[The public-school monopoly] is yet another scam that inflicts disproportionately great damage on people who are the poorest and least advantaged. How could it not? Those who run K-12 government schools aren’t paid by customers who voluntarily send their children to those schools and who could easily choose to send their children elsewhere. Instead, these teachers and officials are paid by governments that tax citizens regardless of how many children those citizens have in schools and regardless of how well the schools perform. Therefore, with funding that is independent of customer choice — and with each child assigned to a particular public school — public-school officials have little incentive to supply good education.

Teaching Computer Science: Those Who Don’t Like to Read

16 Dec 2014 /

Students with books

I recommended a couple of books that I’ve read recently and liked — Unbroken by Laura Hillenbrand and Thinking, Fast and Slow by Daniel Kahneman — to the class in case anyone was looking for a book to read over winter break or maybe as a holiday gift.

“What if you don’t like to read?” someone asked.

“Well, in that case you can spend your entire life inside your own head and never know or care what life looks like to other people.”

In hindsight, it occurred to me that I could have suggested audio books for people who don’t like to read, but . . . woulda coulda shoulda, you know what I’m saying?


Many Have Long Known …

14 Dec 2014 /

Many in academia have long known about how the practice of student evaluations of professors is inherently biased against female professors. . . .

 
  1. Group A getting better evaluations than Group B is not evidence of bias.
  2. Asserting that something is true doesn’t mean it’s true.
  3. Asserting that many people know something to be true doesn’t mean it’s true.
  4. Most college students (i.e., the people evaluating professors) are female. What, if anything, does this fact suggest?

Teaching Computer Science: No School Before Thanksgiving

26 Nov 2014 /

There was no school today because a lot of kids don’t like to show up the day before Thanksgiving, so the district decided not to have classes on the day before Thanksgiving. Once they get used to having Wednesday off, they won’t show up on Tuesday and we’ll have to give them Tuesday off. Then of course there’s no sense in having a one-day school week so we’ll give them the whole week off.

And since they’re already off on Veterans Day and the day after Halloween, let’s just give them the whole month of November off.

I’m concerned that American education is getting worse faster than we can lower our standards.


I’m in Semi-Solidarity with the Protestors

I support the UC Berkeley students protesting tuition hikes but maybe with a little less conviction than I used to because my kid is a senior and no matter how high tuition goes I won’t be paying it anymore so I hope the boy was in class yesterday and not out causing a disturbance . . .


Teaching Computer Science: Exam Tips from the Pros

18 Nov 2014 /

When I cover something in a review session or study guide, it’s because I know it’s going to be on the test. There were questions during this morning’s test about the workings of several Java methods, all of which were covered in the review session and the study guide. I can’t answer questions like that during the test so if you have questions about review topics, ask them in advance of test day.

Some people seem to think that having an excuse for not knowing something is as good as actually knowing it. “But we hardly spent any time on Topic X in class.” “But we just learned Topic Y yesterday.”

Even if either one of those were true, what difference would it make? It’s on the study guide and it’s going to be on the test.

Given a choice between knowing something and having an excuse for not knowing it, always go with the first option: knowing it.


Teaching Computer Science: Mindset

17 Nov 2014 /
Studying

I’m not comfortable giving people advice that they didn’t ask for, so I usually preface it by saying “Feel free to ignore this . . .”

That being said, I want to talk about the mindset I think you should have for this class, maybe for other classes, maybe even for things outside of school.

Feel free to ignore this . . .

Education has allowed me to make a living doing things that I like and things that I’m good at. A lot of people are not able to say that. Most people, I think, are not able to say that. Most people are like “I hate Mondays” and “Thank god it’s Friday” and that sort of thing.

I have had jobs where I spent the day doing things that I don’t like and I’m not good at and it’s painful. And the amount of money you get paid to do it doesn’t seem to make it any less painful.

I have brothers, sisters, nieces, nephews, cousins . . . some of them were serious about education and some of them weren’t. And the ones who weren’t, I don’t want to say they’re all losers, but they’re all . . . disappointments. As I expected they would be. My wife doesn’t like when I say this — she thinks it’s bad karma or something — but I like it when people screw around in school and go on to have disappointing lives because it reinforces everything that I believe to be true about life.

It’s satisfying when people make bad decisions and suffer the consequences, isn’t it? I think it is.

My own mindset, and this doesn’t apply just to school, is that no one is going to outwork me and no one is going to outlearn me. If you’re working on homework or a programming assignment, or you’re studying for a test or quiz, and you get stuck on something, and you try to get unstuck by reading the textbook, or going to the website and reviewing lecture slides or handouts or watching a video or posting a question to the Facebook group, you’re doing things the right way. You should do well in the class, you should do well on the AP exam and I’ll do everything I can to help you do well in the class and on the AP exam.

If you hear yourself saying things like, “I spent the weekend playing 47 straight hours of video games, and by the way, I have no idea what’s going on in this class,” you’re unlikely to do well.

If you’re asking questions about assignments on or after the due date, you’re unlikely to do well.

If you miss a class and don’t check the website to see what you missed, you’re unlikely to do well. Everything we cover in class is on the website, plus a lot of extra stuff as well.

“Nobody’s going to outwork me and nobody’s going to outlearn me.”

Again, if that doesn’t make sense to you, feel free to ignore it . . .
