Stretching your mind: Arguing for multiple programming languages for designers « Computing Education Blog.

 

Well worth repeating. Also, something I’ve been saying for years.

This is from jruby 2012 and the keynote by Venkat Subramaniam.

Knowing multiple programming languages changes how we design software in any language. It changes how we think about solutions. Most important, it changes how we perceive the world. This is something that monolingual programmers often do not appreciate. When we know several languages well, we see problems — and solutions — differently.

Why learn a new language now, even if you don’t need to? So that you can learn a new language more quickly later, when you do need to. Subramaniam claimed that the amount of time required to learn a new language is inversely proportional to the number of languages a person has learned in last ten years. I’m not sure whether there is any empirical evidence to support this claim, but I agree with the sentiment. I’d offer one small refinement: The greatest benefits come from learning different kinds of language. A new language that doesn’t stretch your mind won’t stretch your mind.

You’ll ‘Want To Protect’ The New, Less Curvy Lara Croft

You’ll ‘Want To Protect’ The New, Less Curvy Lara Croft.

Really? REALLY?!?!

So, I have to ask, who buys this shit? And I don’t care how good the interaction, graphics, or audio.

How can you claim brownie points for making Lara less curvacious when your big selling point is there’s an attempted rape scene?
I know developers claim they are only making it because it sells, and I’m sure it will. That’s one of the lamest excuses there is, right up there with “I was only following orders.”
Censorship is not the answer, but how does the industry ever hope to get any respect when it pulls shit like this?

“The ability to see her as a human is even more enticing to me than the more sexualized version of yesteryear,” he said. “She literally goes from zero to hero… we’re sort of building her up and just when she gets confident, we break her down again.”

In the new Tomb Raider, Lara Croft will suffer. Her best friend will be kidnapped. She’ll get taken prisoner by island scavengers. And then, Rosenberg says, those scavengers will try to rape her.”

“She is literally turned into a cornered animal,” Rosenberg said. “It’s a huge step in her evolution: she’s forced to either fight back or die.”

One of the commenters of the article says, (warning, language…)

So things she’s going to go through that no man will go through or face those ‘challenges’ are and seemingly ONLY include ‘rape’ because fuck all, that’s how women get character ladies in gentlemen, she has to be raped or attempted raped etc…no way in holy FUCKING hell is she going to gain that development through any other FUCKING means from being shot at, punched, attacked, survive a plane crash, betrayal, set on fire…nope, rape. Perfect, that’s the ‘Go to’ for female development to make her ‘Harder and badass.’

I tend to agree. I sure hope one of Lara’s weapons is a burdizzo. That would be highly appropriate.
I have no intention of playing the game to see for myself.

On Giving Zeros to Students

Approximate Reading Time: 3 minutes

There’s a story that’s been circulating around the airwaves in the last few weeks about a teacher who’s been suspended for giving zeros to students who don’t submit work. The suspension is for not doing as he’s told. This school district has decided that students shouldn’t get zeros.

Now, let me say right up front that I think for the most part, students should get zeros for work not submitted (of course there are exceptions – zero-tolerance rules are stupid). I also applaud the teacher for standing by his principles even when his principal won’t (sorry, couldn’t resist).

Quite predictably, much of the professional education community has joined the administration in dumping on the teacher.

Professionals Don’t Use Marks to Motivate | Canadian Education Association (CEA).

Apparently, it is wrong to think of grades as being earned. Apparently, current groupthink says we should be excusing work not submitted and trying harder to cajole students into doing their work, because after all, education is all about motivating students and making them feel a sense of accomplishment (even if they haven’t accomplished anything). I’ll come back to this and go through some of the finer points later. I disagree with much of what is said, but it says it in typical education-ese and deserves a response. It is unfortunate that this article is written without forming logical arguments – the main argument is an ad hominem fallacy. “Professionals” don’t give zeros. Presumably that means that someone who does give a zero can’t be a professional.

 Here’s a well-written response from a long-time university professor.

There are several Facebook groups that have sprung up in support of this teacher. This is one.

This week a grade 11 student from Edmonton has started a petition supporting the giving of zeros and to reinstate Mr. Dorval  (not one of Mr. Dorval’s students I might add).

There is even some suggestion that this no-zero policy is driven by a desire to retain funding.

And still the education establishment insists that it’s bad to give zeros. Some are even saying students shouldn’t be graded at all. (!) What we are supposed to be doing is giving them the information they need to get better. The argument against seems to be largely based on the assumption that grading is punitive. When pushed, most arguments turn into reducto ad absurdum or some other fallacy.

It may surprise you to know that I do NOT approve of competition between students, or, for that matter most forms of competition. That is not the same as being against assessment and the measurement of learning.

I think learning is important. I have been teaching at the university level more or less for 33 years, with the occasional time out for babies, a PhD, and a book. I have spent most of that time teaching some thing (as opposed to meta-teaching: teaching about teaching). I have taught, quite literally, thousands of students – and a few of them still keep in touch.

There are many things wrong with how grading often gets done.
Getting rid of grading does not solve the problem.

Yes, of COURSE getting a zero is discouraging.
Giving no zeroes does not solve the problem. The problem isn’t with the zero, it’s with what happened to result in that zero.

Zeros indicate that the work was not done, NOT the there was no learning.

I’ve got a lot more to say about this, but I’ll leave that for another blog. In the mean time, I have chores to do.  Curiously, if I avoid feeding and watering my animals, they don’t do well. Real life rarely assesses based only on what you did and not what you failed to do. Feeding them really well half the time results in sick (or dead) animals.

Frosty freakout.

OK. This one’s better than the last one. The time element comes into play when you start making your ice cream – the image of what you are supposed to make fades.

 

There’s a time limit, but it is an over-all one, rather than one that beats you down little by little (See last game)

Quickie Game Review: Ice cream game

Approximate Reading Time: < 1 minute

snap02025I’ve been checking out a lot of games recently for various reasons, and it occurred to me that I should keep a record of them. I’m putting them here because they might be of use to someone else too..

Ice cream game – create orders scoop by scoop – tutticuti ice cream parlour – online game.

Good concept – but I HATE this game. It is almost impossible to please more than one customer at a time.
It’s the time thing again…..
There seem to be plenty of games that get this wrong.

A lot of developers seem to think that twitch games are easy – all you have to do is put time limits on everything and it will automatically be “fun”. Well, I have no real evidence for this (if anyone does, please share!), but I think that this sort of thing is de-motivating for a lot of people, but especially for girls.

The bubble shooter is a good example of doing it right – it starts off slow and easy and (VERY) gradually gets faster.

Will More Prominent Colleges Abandon the SAT? | MindShift

Approximate Reading Time: < 1 minute

Are we finally starting to move away from standardized, high stakes testing?

“Standardized test scores add remarkably little to our ability to predict a student’s success beyond what their high school GPA and course schedule already tell us,” Maguire claims. “We believe our new test optional policy better aligns with our holistic and careful reviews of student applications. We also believe the policy will encourage more students to consider Ithaca College and help further diversify our applicant pool.”

“They’re incredibly imprecise,” says FairTest spokesman Robert Schaeffer. “They under-predict for women and over-predict for men, for example. And they’re highly coachable, which gives kids who are already likely to do well another leg up.”

  • The implication? Parents and teachers should choose basic e-books like the Kindle or Nook over enhanced e-books, such as the iPad, if they want a more literacy-focused co-reading experience with children. Prompting kids with questions that relate to the text, labeling and naming objects, and encouraging kids to talk about the book’s content from their own perspective all elicit kids to be more verbal, and can lead to improved vocabulary and language development, the study states.

    But if “engagement” is the objective, the issue gets murkier. When it came time to measuring “child-book” engagement, based on the child’s direct attention and touch, more kids showed higher levels of engagement for the e-books than the print books, though a majority were equally engaged by both book types. Children also physically interacted with the enhanced e-book more than when reading either the print or basic e-book.

  • Matt and colleagues found no significant differences in academic outcomes between the two conditions: students in both courses did equally well in terms of grades, pass rates, and standardized measures of statistics knowledge. This falls in line with many, many other studies that have showed no difference in student outcomes between online (or distance) and face to face courses, and the website No Significant Differences is a good place to explore this research.

    It’s not just that the hybrid course is just as good though; it also took less time from teachers and students. The kids in the hybrid condition had 2 fewer hours of class per week (although they apparently spent an extra 30 minutes per week outside of class). Students learned the same amount with less time investment from students and much less investment in faculty. Its exciting to imagine how gaining efficiencies in certain courses could help students finish school faster and learn more and help universities allocate more resources to more complicated learning tasks. In the radio interview, we discuss more about what this means, how it would not apply to all subjects or learning goals, and why the results are promising.

  • The top time-wasting activities reported were waiting for approval from a higher authority, reading and responding to emails and technology issues.

    Despite many Australians now working more than eight hours each day, productivity had not grown over the past decade.

    Highly productive workers spent two-thirds of their time on meaningful work, they took longer breaks, spent less time travelling to work and allocated more time to leisure and recreation.
