No, it's not, but it does raise a problem with physics questions for those of us who have to
write the questions: we're often doing it on short notice, or are far more preoccupied with making sure the numbers add up than with making the setup of the word-problem aspect convincing.
Get the word problem wrong and you don't embarass yourself- at worst the problem is boring, and teachers aren't punished for boring their students. Get the numbers wrong and everyone who does the problem correctly notice you screwed up. You tell me which kind of mistake the writer is more worried about.
So the setup often doesn't get much thought, and it's
so much easier to write abstract problems than it is to write problems that provide concrete examples which must nonetheless avoid all the forms of offensive stereotyping, including "this perpetuates the idea that women do all the shopping!"
By the time you've done that, the problem defaults to: "Someone pushes a cart with a constant force. When the cart is empty, they can accelerate the cart at 5m/s/s. After loading it up with 15kg of stuff, they can only accelerate the trolley at 3m/s/s. Calculate the weight of the empty trolley."
Which is a perfectly doable problem, but totally un-engaging.
Or are you, too, are now going to go and argue with me that by taking Paris Hilton to be a more topic that will interest girls more than cars, I too am being sexist towards girls, even though I'm not the one doing the fashion magazine marketing which is a major cause of girls being more interested in Paris Hilton than boys are (poor-quality porno video aside).
I don't even know.
The problem is that when doing physics you have to worry about math as it is. Introducing social context into your problems is just an exercise in playing hopscotch in an unnecessary minefield- I once had a professor who got formally reprimanded because he was enough of a dickhead to do a ballistics problem about people jumping off the top stories of the World Trade Center on 9/11.* That's about the worst you can get into in terms of "politically fucking insulting on so many levels," but there are many ways to get it wrong.
The natural reflex for physics teachers is to just
remove the context. It's easier, literally
less work, to create a contextless "person pushes trolley" problem illustrated with stick figures than it is to worry about whether "Paris Hilton is shopping" would be:
-offensive
-viewed as 'silly' by your audience, in a way that undermines their respect for the teacher
-distracting from the problem, as is often the case when a problem encourages students to overthink things
And sitting down and coming up with a problem that has a context but is neither offensive nor silly while still engaging your students by addressing subjects their social conditioning has trained them to care about
without seeking to reinforce that social conditioning by blatantly implying that they should adhere to it...
[takes deep breath]
...well, that takes a fair amount of extra work. It is much simpler, and more often done in my opinion, to remove the context and count on the students
as a whole having enough interest in physics to carry them through.
*Seriously, that guy was a
dickhead. Kind of awesome in a batshit crazy offensively right-winger way, because he was undeniably good at the math and stuff, but
what a dick.
The fact that neutral examples are more frequent than examples using stereotypically** masculine situations in no way disputes my point that examples using stereotypically** masculine situations are more common by far than examples using stereotypically** feminine situations. Pulley and ramp questions are boring enough on their own without the added disincentive of all of the other questions being about basketballers (yawn), missile systems (double yawn) and the gradient of the road at Nascar (zzzzz). A ratio of 70% abstract questions to 30% questions about stuff you're interested is far more likely to get someone interested in a subject than a ratio of 70% abstract questions to 30% questions about boring stuff.
I don't disagree- though the "banking on a highway" problem is one of the classics, that may just be because a bunch of dudes wrote it.
The problem is just that the trend here is going to be, by necessity, towards
gender neutral problems, or more accurately 'neuter' problems, where anything interesting about them that might be gendered has been removed because it's more trouble than it's worth to vet your problems for being gendered-but-not-too-gendered. Especially when the definition of how to give gender to a problem to draw the interest of female students tends to shift, depending on what the most recent round of studies tell us the two genders care more about.
In my department, this has more or less already happened, I think. Though I could be wrong; I'd have to check.
Though looking at
this site does suggest that at least the questions about what angle the rain would fall on a person depending on their velocity are actually likely to be more interesting to female students than male students, because women are apparently a lot more interested in the weather than men. So... yay, I guess?
This illustrates another problem: how much effort does it take to keep up with the latest research on what women are, statistically speaking, more interested in than men? If I try to guess I'll probably guess wrong; I would
never have guessed 'weather' and I doubt you would have either.
What does annoy me, and what I do blame people for, is the fact that when the issue is brought to their attention, rather than turning to their nearest textbook, looking through the questions and saying, "Yes, all of these questions are either gender neutral or stereotypically** masculine. This is an issue I had never noticed before," or saying, "No, you are wrong. My science textbook, at least, has an equal mix of questions designed to appeal to both male and female learners," in which case I would be ecstatic to hear that your textbook is better than mine, all I get is, "Waaah, this doesn't matter anyway, why do you hate MEN?" And, "These are the only things that can POSSIBLY be used as examples, because I am ignoring the examples that you gave not three posts ago!"
Agreed.
And, "I don't like the random examples you pulled out of your arse in an attempt to be humorous, because I am taking them as an example of what should be in a textbook rather than as examples to illustrate that yes, stereotypically** feminine topics
can in questions illustrating physical principles." And, "Well, actually, it's YOU being sexist, Miss "pink ponies are for girls and blue cars are for boys". On what grounds do you base this? Hmm? Hmm?
"
Hey, give me a break. I am not attacking you, I'm pointing out a problem that can turn around and bite
me if I try to do something like the Paris Hilton problem.
Because the
opposite problem can crop up then: if I write 100 problems about shopping and say I'm doing it to keep women interested in the work, someone is (legitimately) going to point out that this is itself making and reinforcing a stereotyped assumption about women. Or at least
I am (legitimately) going to worry that someone might, because shit, if I saw someone doing that I would probably say something.
At which point I have to pull out a sheaf of scientific studies saying female students are 15% more likely to pay attention to problems with 'shopping' identifier tags, and 20% less likely to pay attention to problems with 'cars' identifier tags, while the reverse is true for male students, and I have to balance my problems so that X% of them have 'feminine' tags and Y% have 'masculine' tags (because I don't want to lose the male students either), and somehow get the numbers right and...
[collapses in exhaustion at prospect of actually having to do this for an extended period of time]
Actually, what I'm going to do is say "screw it" and write all my problems about boxes on ramps. I have deadlines to meet. Not because I'm trying to be part of the wall of oppression here, but just because I'm a person with 24 hours in a day.
If someone can come up with a way to fix this that doesn't create a serious burden of carefully vetting the social context of their physics problems against a small hill of research on which subjects interest which gender how much, and then place this burden on the people who write the problems,
great. If not, please try to understand that having to do this does impose a considerable extra burden of work, with only a limited potential for payoffs that aren't zero-sum game.
