More People I’m Sick Unto Death Of: High School Gun Experts

 

I’m burned out on the high school gun “experts” for a couple of reasons: They’re rude. It’s too obvious that someone or a collection of someones is scripting their talking points. I heard one of the kids raising an obscure point about record-keeping requirements at the ATF. Most gun control advocates are not even familiar with the basic mechanisms and terminology of guns, let alone with ATF policy minutiae. That’s something a gun control lobbyist would know about, but it’s not something a high school kid knows about, unless it’s scripted out for him. I don’t object to the anti-gun message, although I disagree with most of it . . . I object to being treated like the kind of rube who can’t tell when a high school student is plagiarizing someone else’s ideas. Also: these kids have a platform, not based on their own merits, but because 17 other… Read more →

Teaching Computer Science: The Phones Aren’t Helping You

 

I’m volunteering a couple mornings a week at a local high school, helping out with computer science classes. The way the classes are taught, via an online curriculum, provides a great temptation to kids to get off-task, which they do, usually by entertaining themselves with their phones. They get off-task in other ways too — web surfing, doing homework for other classes — but the main distractor is the phones . . .   “As I mentioned before, I worked with another CS class a couple years ago. No phones allowed in the classroom. “I remember one day the assistant principal was in class observing . . . a student had a phone out, looking at it . . . he was holding it under the table so no one could see it, but this guy, the assistant principal, he did see it. “Oh man, did he hit the roof!… Read more →

Teaching Computer Science: When You Need Help, Ask For Help

 

I’m volunteering a couple mornings a week at a local high school, helping out with computer science classes. It’s a mixed class . . . most of the students are taking AP Computer Science Principles, and about 10 kids just recently started a second-semester Visual Basic class. The VB kids were pretty inquisitive at first but started to get discouraged . . . in my opinion because of the way the material is presented to them via an online curriculum. The current approach to teaching computer science in American schools, because of the shortage of (I almost said “lack of”) qualified teachers is to use packaged courses delivered to students online. My observation is students assume that because they’ve been put in front of a computer full of lessons, they’re expected to be able to read and understand the material and complete the assignments on their own with no help.… 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 →

Teaching Computer Science: It’s Not Easy to Teach a Subject in Which You Have No Training

 

A recent issue of Science has an article on the pipeline for computer science teachers . . . The first sentence says, “It’s not easy to teach a subject in which you have no training.” That could be the whole article, really. That’s about all you need to know about the current state of computer science instruction: It’s not easy to teach a subject in which you have no training. Cameron Wilson, chief operating officer and president of the Code.org Advocacy Coalition, is quoted as saying, “It’s really hard to convince a computer science professional to give up a job that pays up to three times more to pursue teaching. And I don’t think we should.” Wilson’s opinion that computer science classes should not be taught by someone who actually knows something about computer science is probably influenced by the fact that Code.org is one of the leading providers of… Read more →

What Does a Programmer Do?

 

I was asked to give a talk last week to a high school computer science class on “What Does a Programmer Do?” (I’m indebted to Jim McCarthy for the “lords and ladies of logic” section.)   Programming is problem solving. At the highest level, the problem that programmers solve is that people want to be able to do things with computers that they can’t do. And by computers, I don’t mean just the kind of computers you have on the desks here, I mean phones, watches, cars . . . more and more different kinds of devices are running software. So one good thing about being a programmer is that pretty much every field of endeavor now uses software and data. You can work at a tech company like Microsoft or Google or Twitter or Facebook, but you can also work in healthcare, finance, education, sports . . . you… 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 →

AP Computer Science Revisited

 

I got a LinkedIn invitation today from a student I taught in an AP Computer Science class a couple of years ago. She’s now a computer science major at UCSB. Several of the kids from that class are now in college as computer science majors. Some of them would have been computer science majors anyway, without the class — they came in already having programming interest and experience — but this young lady was not in that group. She was quiet in class but when I worked with her one on one, she asked a lot of questions. She asked them quietly but she asked. And when I told her to do something a certain way she always asked why. She only has four connections at this time so I appreciate her thinking of me. 🙂 Read more →

Harper Lee, 1926-2016

 

28 Sep 2008 I took my son to the bookstore to buy To Kill a Mockingbird for his English class. They had two paperback editions available — one with a fancy binding for $15.95 and another one for three dollars less. I pulled the cheaper one off the shelf and my son asked, “Why are we getting that one?” I said, “Because it’s three dollars less for the same book.” “I like the other cover better,” he said. “Gimme three dollars.”   23 Oct 2008 FATHER: Would you take out the trash please? SON: Are you KIDDING?! I’m doing homework! I’ll take out the trash if you read To Kill a Mockingbird and tell me what each chapter is about. FATHER: I’ve read To Kill a Mockingbird. You want to know what it’s about? ‘Racism is Bad.’ Now take out the garbage.   RIP Harper Lee Read more →

Huckleberry Finn Banned Again

 

A Pennsylvania high school has removed Mark Twain’s Adventures of Huckleberry Finn from its 11th-grade curriculum after complaints from students who said they were made “uncomfortable” by the novel. The school’s principal defended the decision to remove the book from the curriculum. “I do not believe that we’re censoring,” he said. “I really do believe that this is an opportunity for the school to step forward and listen to the students.” He went on to add, “War is peace, freedom is slavery, ignorance is strength.” Because if suppression of material you deem objectionable is not censoring, what is? As Kurt Vonnegut used to say, “Have somebody read the First Amendment to the United States Constitution out loud to you, you God damned fool!” Read more →

Teaching Computer Science: The Last Day

 

On the last day of class, I gave students the code for a partially working Space Invaders game, along with instructions for adding collision detection and completing the implementation. The instructions didn’t leave too much to the imagination because I wanted to give everyone a chance to finish out the year on a successful note. I estimated it to be about a 30-minute activity. It didn’t occur to me that that students would do anything but finish the program and spend whatever time was left over blasting aliens. What they actually did was, they finished the program, tweaked the firing interval so they could shoot faster, changed the speed of the sprites, added more aliens, changed the program to shoot two bullets at a time instead of one, changed the program to shoot five bullets at a time, enabled the aliens to drop bombs, had the game recognize that when… 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: Extra Credit

 

I wish I got a dollar for every time a student asks, “Can I get extra credit for [insert action for which it makes no sense to give extra credit]?” Today in class we did a difficult programming exercise. It wasn’t graded but I asked everyone to turn it in so I could evaluate the difficulty of the assignment. “Can we get extra credit for turning it in?” a student asked me. “How does it make sense to give extra credit for turning it in? Everyone is turning it in.” “It raises everyone’s grades,” he said. “Like a rising tide lifts all boats.” 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 →

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 . . . Read more →

Teaching Computer Science: Pro Tips for Finishing a Project

 

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. 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. 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. This is what your program needs to do: [Feature list goes here]. 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. Repeat Step 5 until done. Read more →

Teaching Computer Science: Ski Week

 

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. Read more →

Teaching Computer Science: Lessons Learned

 

We did a programming lab in class . . . before we started, I mentioned several times that Java code that would be useful for the lab was posted on the class website. So it surprised me that several groups got stuck during the lab when they got to the part where the sample code would have been useful because they didn’t go to the website and download the sample code. Going forward, I will preface important announcements by saying “I cannot emphasize this strongly enough . . .” while pounding my fist on a solid object. Read more →

See You in Hell

 

[See You in Hell is a feature by our guest blogger, Satan — PE] Greetings from the underworld! I just read about a father and son teaming up to punch out the son’s high school basketball coach because the teen wasn’t getting enough playing time. What a heartwarming story! A lot of young black men don’t have a male role model in their lives. See you in Hell . . . Read more →
