The Dartmouth student newspaper reports on a study finding that gender affects an individual’s perception of women’s anxiety in STEM disciplines. Men are more likely than women to attribute this anxiety and self-doubt to internal factors, while women usually attribute such emotions to external factors. Participants in the study read one story, among a selection, about an undergraduate woman taking a STEM class. In the stories, based on the experiences of actual undergraduate women in STEM, the female main character expressed having anxiety or self-doubt. It was ambiguous whether the instructor in the stories harbored any biases against women. According to research team leader Mary Flanagan, “Women identify the problem as something that is familiar and men identify the problem as something that is a particular student’s problem. Men are not seeing the systemic biases as much as the women are. That is something that we need to address in deeper… Read more →

Teaching Computer Science: How to Get Top-Notch Teachers in the Classroom
I read something every day where educators and/or elected officials are talking about the importance for our kids, our country, our future, etc., of teaching computer science, the sticking point being an extreme shortage of qualified teachers. A person entering the workforce with a computer science degree is unlikely to go into teaching because of the opportunity cost: they can earn a lot more money as a software engineer. The likelihood of getting a mid-career tech industry professional to switch into teaching is even lower. Teacher salaries are based in large part on years of service. A mid-career person switching into teaching is not going to get a mid-career teacher’s salary, they are going to get a first-year teacher’s salary. So here’s the idea: Give CS professionals the opportunity to apply their years in industry to years of service as a teacher. It’s still a pay cut going from software… Read more →
Two Reasons For the Low Number of Women in Computer Jobs
I saw this chart on LinkedIn with the heading “Chart: Women in tech continue to face uphill battle” and the hashtag #STEMSexism. The first reason for the low number of women in computer jobs is that we rarely hear about women in computing except in the context of pay gaps, harassment, discrimination, “uphill battles” and #STEMSexism. It’s self-perpetuating. “Computing is a terrible profession for women in so many ways.” Followed by “Why aren’t there more women in computing?” You’ve answered your own question. If you think computing is a hostile profession (I do not, btw), why do you want more women to go into it? The second reason for the low number of women in computer jobs — sometimes the simplest explanations are the best — is that women prefer to do other things. Men and women are different and make different choices about their lives, as a result… Read more →
Teaching Computer Science: Asking for Help
I’m volunteering a couple mornings a week at a local high school, helping out with computer science classes. This morning, in AP Computer Science Principles, the teacher went through an explanation of the hexadecimal number system, then gave an in-class assignment for students to convert their cell phone number to hexadecimal. Not in two parts, 3 digits and 4 digits, but as a 7-digit number. It seemed pretty obvious from the interaction and the body language and the looks on their faces that a lot of students didn’t get it, but in a class of 25 students, only one student asked for help. Until the teacher finished with that student and asked “Does anyone else need help?” and eight more students immediately raised their hand. I asked the teacher, “Can I address the class for a minute?” “First off, doing a 7-digit hex conversion is not easy. I know… Read more →
Making it Through High School Alive
Baltimore schools spend a staggering $16,000 per student – the fourth-highest rate in the nation – and still an investigation by Fox45’s Project Baltimore revealed that at six city schools, not one student scored proficient on the statewide tests for English and math. At West Baltimore’s Frederick Douglass High, one of five high schools and one middle school where not one student scored a four or a five on the state test, only one out of 185 students who took the test last year scored a three, while 165 students scored a one, the lowest possible score. — Zero Hedge The schools are: Booker T. Washington Middle School Frederick Douglass High School Achievement Academy at Harbor City New Era Academy Excel Academy at Francis M. Wood High New Hope Academy It looks like if you live in Baltimore, you want to avoid sending your child to a school whose name… Read more →
To Young Women Considering a Career in Technology
You’ve probably read a lot of articles about how sexist and awful the culture is for women in technology. I think if anything deters young women from technology careers, it’s this glut of articles saying how sexist and awful the culture is. I’ve worked in software development for 30 years. In my experience — and feel free to discount this because I’m not a woman — the culture is not tough for women. If anything, men give women the benefit of the doubt because they’d like to have more women around. As Holden Caulfield used to say, “I like to be somewhere at least where you can see a few girls around once in a while, even if they’re only scratching their arms or blowing their noses or even just giggling or something.” Yes, I have seen bad things happen to women in tech, but I’ve seen bad things happen… Read more →
10 Reasons That NY Times Chart Might Not Mean What You Think It Means
From the New York Times: Money is not the only metric for measuring life outcomes. Charts and articles like this seem to reflect an inappropriate obsession with narrowly materialist values. If you do want to measure your life with money, it looks like the 99th percentile is where you want to be. Why aren’t you there? Why aren’t you a CEO? Why aren’t you making a million a year? If you can’t figure out how to get there, don’t begrudge the people who did figure it out. If you don’t have the education, motivation, intelligence or skills to get there, don’t begrudge those who do. The amount of wealth is not a fixed amount. It’s not a zero-sum game. If it were, it would be concerning that a few people are very wealthy. But it isn’t. The distribution of income has to be skewed to the right because income is… Read more →
Why Are Black Americans Against School Choice?
Most or all of the people booing Betsy DeVos know little or nothing about her except that they’re expected to dislike her for reasons that they may know are related to her views on public schools and school choice. But why are black Americans against school choice? I don’t want to overgeneralize — my son went to public schools and got a good education — but it’s all on the kids and their families to make it happen. Again, not to overgeneralize, but most public schools in black neighborhoods suck big time . Without school choice, public schools don’t have the right incentives. People running public schools aren’t paid by customers who voluntarily send their kids to those schools and who could choose to send their kids to another school if they wanted to. Public schools are paid for by taxing citizens who may or may not have kids in… Read more →
Strong Opinions on Betsy DeVos
I’m seeing on Facebook that a lot of people have strong (negative) opinions today about Betsy DeVos, who has been nominated as Secretary of Education, despite the fact that 99.9 percent of them had never heard of Betsy DeVos until about five minutes ago. Why do people suddenly have a strong opinion about someone they’ve never heard of? How is this possible? Because they’ve been instructed to have a strong opinion about Betsy DeVos in order to be consistent with the image that they have of themselves and the groups they want to fit in with. BTW I have no opinion about Betsy DeVos at the moment because I had never heard of her until about five minutes ago . . . Read more →

Shake it Off (aka Haters Gonna Hate)
A Chinese woman tells me that being around white guys inhibits her ability to make edgy (i.e., racist) comments about white guys . . . I reply, “White guys didn’t get to be what we are by peeing in our pants and crying for our mamas every time someone calls us a name. Haters gonna hate. That has been amply demonstrated. We’re just gonna shake, shake, shake, shake it off.” Some people are offended by absolutely everything, some people are offended by nothing, and everyone else is somewhere in between. The people at the easily offended end of the spectrum get most of the attention. People who hear a trigger word or a dog whistle that wouldn’t bother a normal person and they’re bleeding out all over the place like hemophiliacs. That’s where most of the focus is, it seems to me. It’s a distorted view of reality. My… Read more →
The People v. O.J. Simpson
There’s a miniseries coming out called The People v. O.J. Simpson: American Crime Story. I’m not going to watch it, not for any singular reason — I don’t watch other TV shows either — but I don’t remember the Simpson trial having a great deal of entertainment value. The trial proved beyond a reasonable doubt that Simpson was guilty, even though a guilty verdict was not returned. Eight of the 12 trial jurors were black women. The prosecution believed that the jurors would identify with the female victim. The defense team believed that the jurors would identify with the black murderer. The defense was right. Conventional wisdom says that anyone who can’t get out of a lengthy term of jury service is not very bright. Only two of the Simpson jurors had a college degree. One never finished high school. The prosecution bored and confused them with DNA evidence. The… Read more →
Are You Smarter Than a Common Core Algebra Student?
You can test your Common Core algebra skills against a 5-question sample test courtesy of the the New York Times. For all the controversy about Common Core, the questions seem pretty basic even for a person with an aging brain (I frigging CRUSHED it with a perfect 5 out of 5), the one exception being a graphing problem that should separate the mathematicians from the wannabes. How hard is New York's high school algebra exam? 5 questions to test your math skills. Posted by The New York Times on Monday, November 30, 2015 Read more →
The Ceiling Seems Very Low
I don’t know if this is good news or bad news. It would help to know what “trains” means but I read the article and it doesn’t say. Reporters need to be more inquisitive. Can someone with no knowledge of computer science or programming be “trained” to teach computer science or programming? What would that entail? How long would it take? Can someone who’s never played an instrument or listened to a piece of music be “trained” to teach a music class? Can someone who’s never picked up a drawing pencil or visited a museum be “trained” to teach an art class? Can someone who doesn’t speak Spanish be “trained” to teach a Spanish class? The ceiling on any of these approaches seems very low compared to hiring actual programmers, musicians, artists and Spanish speakers . . . Thus spoke The Programmer. Read more →
The Bamboo Ceiling
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).… Read more →
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 . . . Read more →
Teaching Computer Science: Ask More Questions
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,… Read more →
Teaching Computer Science: Combating Procrastination
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: 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. 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… Read more →
