The younger son had forgotten a text book which he needed to do an assignment, so I told him that he should get done what he could and try to finish it up in the morning.
But mom…she doesn’t accept work unless it’s completely done.
She may not, I told him, but your future teachers probably will, so it’s a good habit. At least she’ll see you made some effort on it.
There were several classes I’ve had throughout college where I didn’t complete the entire assignment. Frankly, sometimes I just couldn’t. Or maybe I was short on time. However, handing in 8 out of 9 problems, even if it didn’t earn me a perfect grade, certainly earned me enough to get a very high grade in almost all of my classes.
I really don’t like this policy of “it has to be completely done, and I won’t accept anything late.” I totally get not accepting anything late, but I think the “completely done” thing is bunk. I would rather a student put it in a thoughtful, partial attempt than not do anything at all. The feedback I would provide as a teacher may be helpful to the student, too.
The notion of “all or nothing” feeds into perfectionism, particularly the kind that leads to paralysis and lack of motivation. “It’s not worth it to do anything if she won’t accept incomplete work,” is the kind of mindset I grew up with. Now that I teach, I know that every effort you make on your homework or on learning something will not be wasted effort. Few people ever get any topic 100%, but putting in time and effort will get you closer.
I would always tell my students to put the best effort you can into your homework and then go to the teacher for help on the rest. Teachers would rather see an effort or an attempt to solve something rather than a student who shows up empty-handed and saying, “I don’t understand.” It’s very hard to understand how to help the student unless you can see where they’re struggling.
This is a good life skill to have, too. Is it better to wait to clean the kitchen fully or should you at least take 10 minutes to do what you can? Personally, I try to do what I can because I seldom have blocks of time to allow me to do things with the full depth and effort I would like. You can make progress doing it a bit at a time. It’ll never be as fast as you want, but it’s better to keep doing it than forget it because you can’t do it ‘right’. Once it’s done, it doesn’t always matter how quickly you did it.
It also dissuades people from trying new things. “Oh gee…I can’t cook crepes perfectly the first time out, so there’s really no point in trying.” Honestly, a mangled crepe is almost always better than no crepe at all. More importantly, you’ll learn from the experience.
I am therefore doing my best to teach my son that some effort is far better than no effort. There are few things in life that we can do as well and fully as we like, so I want to disavow him of the notion of “all or nothing” right away.
Stop telling boys to go into STEM December 18, 2014Posted by mareserinitatis in education, engineering, feminism, science, teaching.

Stereotyping is always a bad thing, and most people don’t realize that men suffer just as badly from stereotypes as women.
Let’s look at science: there has been a ton of work going into how to attract girls and women into scientific endeavors, particularly those that are very math-intensive. Much of the discussion centers on countering two issues: the first is the societal expectations that women go into ‘caring’ professions like teaching and nursing and the second is the stereotype that men are better at math. There is nothing wrong with these efforts, but there’s a flip side to this stereotype that has a negative impact on men: there are a lot of men who go into STEM fields (probably engineering moreso than science) that probably don’t belong there.
Lest you think I’m just being negative toward men, this is actually something a man told me. I had an English professor who was one of the best college teachers I’d had, I think in part because he was very knowledgeable in science. In fact, he’d received a degree in engineering from Stanford but then shuffled around for several years before finally getting a master’s degree in English. During one conversation, I asked him why he got a degree in engineering when he really loved literature.
There’s a strong expectation that if you’re a smart boy who’s good at math, you’re going to go into engineering. That’s what everyone expected, so that’s what I did.
During the course of my teaching career, I’ve seen a lot of this. I like to have students write me an introductory essay so that I can learn more about them and what they were hoping to learn from the class. Many of them reiterated almost exactly what my professor said: “I went into engineering because I was told it was a good career for someone with good math skills.”
I’m not saying it’s not a good career for someone with math skills of either gender. However, making a career choice should not be an either/or proposition based on problem-solving ability (lots of careers use that), and people are multi-faceted. People can be good at math as well as art, literature, music, biology, communication, caring for others, etc. Just because you’re good at something doesn’t mean that’s what your calling is nor necessarily where you should focus your energy.
While the majority of my best students were men, strictly as a result of the skewed sex ratio in my classes, the women were almost always in the top 20% of the class. None of them were there simply because they were good at math: they almost always really wanted to be an engineer. However, the least engaged students were always men: a lot of them were there because they hadn’t found their passion and felt they had to do something. Engineering was it.
The flip side of the ‘men are good at math’ stereotype is that many of them go into it even when they would be much better off doing something else. They’re discouraged from pursuing more ‘feminine’ careers and made to feel like failures if they don’t enjoy it.
So do the boys a favor: if they’re not sure where they want to go, don’t make engineering the default answer even if they are good at math.
Yo mama is SO stupid she can’t explain plate tectonics! December 4, 2014Posted by mareserinitatis in education, feminism, science, societal commentary, teaching.
Tags: children, communication, feminism, science, science education, sexism
When selling something or conveying information, particularly when it is technical, one wants to make it easy and understandable. Unfortunately, one of the most common approaches I’ve seen is to say one needs to make it easy enough for an older woman to understand, particularly a mother or grandmother. One example of this issue was the IEEE article posted about the making of the Arduino that was erroneously titled, “With the Arduino, Now Even Your Mom Can Program.” They corrected it and apologized.
Last week, I came across another one about having a “grandmother talk.” Once people got upset about the sexist trope, the author changed it. However, it was more out of frustration because people weren’t paying attention to his main point about communication. (Note: if you piss off half of your audience with your title, chances are your communication may weak in certain areas.)
I don’t understand why they don’t just come out and title these things as such:
Yo mama is so stupid she can’t program an Arduino
Yo nana is so stupid she can’t science
I don’t think anyone would intentionally pick on grandma, but they apparently do so without realizing it.
The problem with using this terminology is that it assumes older women have no interest or ability when it comes to technical or complex information. Frankly, I’m pretty sure that, with the right instructions, both my mother and grandmother could handle a lot of technical topics. Being older females, however, people often assume that they are too ignorant to really learn things in depth. But despite myriad counter examples, the stereotype still exists. Some women really have little interest and ability in science, but there are also many, many women who are exceptionally talented scientists and engineers.
I have not yet seen, however, what seems to me a much better analogy: the kid talk. What if your kids ask you questions and you have to simplify it to be developmentally appropriate or to meet the constraints of a limited attention span?
When I try to make things understandable to kids, I take the approach that there may be developmental challenges that they’re not ready to meet, such as a particular level of abstract reasoning. Perhaps they don’t yet have enough math to follow the technical details of a topic. There is also the reality that even the most mature five-year-old is not going to listen to me go on and on for hours about a particular topic, except perhaps Legos. The point of meeting them where they’re at is not because they are ignorant but because they’re inexperienced and uninformed. While I suppose a few would get offended at such a characterization, it also acknowledges that they’re capable of learning more once they’re a bit more mature or if they have a particular interest. It gives you some wiggle room, and you don’t have to stereotype anyone or be condescending.
I decided to put this into practice and once asked my older son to sit in on my classes. He would’ve been a year or two younger than most of the kids in the class, but being tall, he blended in very well. (It also helped that we don’t have the same last name.) I felt the information would be useful for him, but I also wanted to get his take on what parts were confusing or needed work. Beyond actually having a kid give you live feedback (because, let’s face it, they aren’t always available), it’s useful to even contemplate explaining concepts to kids.
There are a lot of marketing slogans to the effect of “so easy, a kid could do it,” but science and engineering communicators don’t generally seem to think this way. Part of the problem is that they don’t view children as a potential audience, even though I think they’re a rather important subset of most groups. I’m not saying you have to communicate on the level of a four-year-old, but an educated and curious 14-year-old will get you a long way. I wonder if science would be more interesting if we saw these kids as our intended audience in most communication ventures. At the very least, I’m sure there’d be more jokes.

I was recently having a conversation with a friend about teaching when she launched into a complaint about students not understanding logarithms. The conversation became somewhat off putting because this friend fell into the trap of equating mathematical knowledge with intelligence. A lot of people do it: English majors will imply one is an idiot if one doesn’t appreciate the succinct stoicism supplied by Hemingway, for example. (And I use this example because I’ve been on the receiving end of such criticism: I can’t stand Hemingway, and it was torture having to relive it when the older son was reading and explaining Old Man and the Sea for one of his classes.) Hemingway hating aside, many of us tend to use certain sets of knowledge as a reflection of intelligence, and that’s rather simplistic (and not all that intelligent of us).
The reason this particular discussion irritated me is because there is a level of classism that seems to go hand-in-hand with assumptions about mathematical literacy. While being mathematically literate is a good thing, the reality is that I’ve met very mathematically illiterate folks who were able to navigate through life with no problems. Not knowing logarithms didn’t hinder them professionally or personally. Not knowing logarithms was no indicator of their intelligence. Not knowing logarithms didn’t stop them from appreciating, or at least tolerating, Hemingway.
In my experience, math illiteracy often has a basis in background. Kids whose parents are highly educated and/or wealthy often have a greater chance of both being exposed to advanced math concepts as well as being able to use such concepts more proficiently. In my classes, I’ve noticed a huge problem: kids from larger, urban schools and who aren’t minorities seem to be more likely to stick with engineering than either minority students or those from rural backgrounds. Kids who have engineers in their family are more likely to stick with it, as well. While this isn’t a surprise, and there’s been a lot of explanation as to why this is so, I suspect exposure to and comfort with math concepts is a big factor. Not only are they already feeling at a disadvantage because they are having to start farther behind their peers in the curriculum progression, they are often advised to change majors because their lack of math implies they aren’t cut out for the rigors of a technical profession. I’ve heard about this happening to my students as well as it happening to me. (I was once told that I should never have been accepted to college because I didn’t know Euler’s formula giving the trigonometric form for imaginary numbers.)
Living through those types of experiences has made me go out of my way to ensure that my kids have an excellent background in math before entering college. At the same time, because I’ve made a point to provide that level of education, I’ve become aware of many kids who don’t have those opportunities. There are a lot of bright kids who are forced to stick with grade level instruction despite the fact it’s obvious they’d benefit from acceleration. And then there are the kids for whom rigorous instruction and acceleration aren’t possible because it’s beyond their parents’ means and ability.
Back to my friend, it was hard to convince her that these kids weren’t stupid, and she seemed unwilling to accept that there wasn’t something wrong with the world that kids who don’t understand logarithms can actually go to college. I apparently couldn’t convince her that they’d be okay and maybe they just needed a bit more guidance to assimilate into the world of mathematical literacy. Perhaps we should’ve discussed literature instead.

The younger son recently started his pre-algebra class. Somehow, this has made math a bit better. I think the fact that it has algebra in the title makes him feel very accomplished and that, in turn, has made him more enthusiastic about math.
The other day, he was doing some of his homework, and the lecture was confusing to him. I listened to the lecture and then said, “It makes more sense if you draw a picture.” He responded that, “Pictures always help me learn better. I guess the math program doesn’t realize that some of us are visual learners.” I was both amused and quite stunned. I think I’ve been discussing educational theory a bit too much at the dinner table. I can tell he’s listening to us.
Tonight, he hit a milestone. He called Mike over, and I followed, so he could ask us how to pronounce “pythagorean.” He was sure he’d heard us talking about it before (yeah, we discuss this stuff around the dinner table), and he wanted to be sure that was what it was.
“Oh, wow!” I said. “You’re doing the Pythagorean Theorem. That’s awesome!” Suddenly, there was an impromptu round of cheering and high-fiving. The older son even came over and gave his little brother a big hug, saying, “Woo hoo! The Pythagorean Theorem is awesome.”
As the lecture progressed, it reiterated the terminology, focusing on right triangle legs and hypotenuse. Given I’ve had ZZ Top in my head, I had to immediately sing, “She’s got legs! She has a hypotenuse!” I wasn’t able to come up with much more, though.
Yes, I have to admit that I realized how odd it was, in retrospect. We were having a celebration that younger son had made it to the Pythagorean Theorem, and we were all making a huge deal about it.
But younger son didn’t think so. He thought it was awesome and giggled continuously for the next few minutes. I guess he likes having a math cheer team.

The older son is a lot of fun. Despite his statements that he has no desire to go into science, he seems to get and make a lot of science jokes. I know he’s not a scientist, but I feel comfortable that he’s scientifically literate. As he was homeschooled, I’m feeling pretty proud of myself.
I’m more anxious about the younger son, though. This weekend, he brought home his science homework, which focused on optics. The kids were studying filters, and one of the questions asked about what kind of light would you see if you shined a flashlight through a blue filter and then a red one. I asked him what he saw, and he said nothing. Unfortunately, he was told that he saw nothing because the flashlights just weren’t bright enough, but that what he should have seen was purple.
I’m pretty sure that if I had ever been bombarded with gamma rays in the past, I would’ve turned into She-Hulk at that very moment and started smashing things. Fortunately (or unfortunately, if being She-Hulk happens to be a goal of yours), that didn’t happen.
I find it infuriating that, throughout my years of homeschooling older son and teaching younger son math, I have constantly been questioned about my ability to teach them. The implication has always been that I may have a degree, but they are experts on teaching. In fact, this particular teacher attempted to take me to task earlier this year about the younger son’s math curriculum…the same teacher who apparently doesn’t understand that light and pigments work completely differently.
After I managed to calm down, I explained that light filters are like sieves, except that they only let one size of particle pass through: nothing bigger can pass through the holes, but nothing smaller can, either. After this explanation, the younger son was able to correctly explain that the reason he saw no light from his flashlight is that the two filters together had blocked all the light.
I’m going to be watching very carefully to see what kinds of scores he’s getting on his answers and whether the teacher realizes she made a mistake. This was very disappointing. There was a new science curriculum introduced this year, one which I was very excited about. The focus was supposed to be on hands-on, problem-based learning, which is great for science. Despite that, it seems that younger son’s science education may be lacking. What good does it do to have a top of the line science education curriculum (or math…or anything else) when our teachers don’t understand what they’re teaching? And how is it that these same teachers can justify questioning the ability to teach material that some of us understand far better than they do?
Curriculum litmus test February 14, 2014Posted by mareserinitatis in engineering, physics, teaching.

I received the written comments back on my student evals from last semester. I had a number of students who were very annoyed with the final project. The previous two years, the final project consisted of a Matlab project. After thinking about what a pain that was, I decided to change to a new project: a paper of 10-15 pages that has each student discuss their goals for getting through college. The general consensus among those who commented was that the project required too much work for a 1 credit class. There were several comments about how most of the other sections of this class don’t require as much work as I do, but the paper was just too much.
I’m sort of used to the comments about how much work my class is. I state up front that they can expect 2-3 hours of homework each week…for a 1 credit class (that is, we meet once per week for an hour). I also figure they had better get used to it, given the expectations of many of my colleagues.
I did find the comments slightly disturbing, however, because the implication seems to be that what I’m asking them to do is a lot of busy work. In a lot of classes, many students feel that they’re spending a lot of time doing things that they will never do again outside of college. They’re right, in a lot of cases. I took a ton of math as an undergrad, and Mike likes to tell people that I’ve forgotten more math than he ever learned. Sadly, the longer time goes on, the more I think he may be right.
The class I teach, however, is an academic skills class. This means I am teaching them how to get through school, particularly in the engineering curriculum. Do you know how to take notes? What are the key things that are important? Can you write a lab report? Do you even know what area of engineering you’re going into?!
These are the things I’m trying to teach them. My goal isn’t even to get them through the engineering curriculum, though a lot of the things I assign may be geared that way. I simply want them to get through school and graduate. I tell them this. It perplexes me, therefore, how they can view setting goals as a waste of time.
I really have put a lot of thought into my assignments. I want this class to be useful, and so I ask myself if each activity is something that will help them learn a skill they’ll need to get through school. In a lot of ways, I’m at an advantage: college is a very constrained environment, and I can tell what skills are useful until they graduate. After they graduate and get a job, however, their classwork may or may not be very valuable. It’s something that simply can’t be predicted.
I have had students come back to me and say that they are really glad I taught the class and they do use the skills that I taught them. I’m just not sure, however, how to make it clear to the freshman in my class that I really am not trying to torture them and that I do want them to succeed. I can only hope the ones complaining about writing their goals are so motivated and driven that a lack of clearly stated goals has absolutely no bearing on their performance in school over the next 3 1/2 years.

Coming to the end of the semester is an unsettling thing for me. I like to do something fun, like bring treats, although I always make sure to do that the week AFTER we’ve had evaluations. Once someone accused me of trying to butter them up…
But beyond that, I am left with this curiosity. I wonder how the students will do continuing on. I wonder if anything I’ve done has helped them. And, to be honest, I wonder if they’ll even remember the class a few years down the road…at least for something other than being the only female college instructor that many of them will encounter.
Anyway, it makes it awkward because it’s not something you can easily convey. I’ve always enjoyed teaching the class, and I let them know that. I tell them I hope they’re successful in their future endeavors. I’ve even considered giving them the Vulcan salute…although I’ve never followed through on it.
But there’s a bit of a melancholy feel as I’ll probably never know what happens to most of them.

I’m digging myself out of my grading hole, albeit very, very slowly.
I have to admit that reading these essays is kind of fun. At least some of them. There was at least one student so far who wrote that s/he needed no improvement in their time management skills…and then on about page five of the essay, it suddenly stopped with a request for an extension/redo. It’s really hard not to be snarky when things like that happen.
Most of them discuss the same issues, which is not a surprise. I’ve had a couple, though, that were quite interesting. My favorite so far is the student who compared getting through college to Lord of the Rings. Although there wasn’t a parallel for every goal I wanted them to discuss, there were a fair number of references.
I really enjoy it when I get to see a bit of creativity and personality creep into these things. I also like seeing how much their views have changed since the beginning of the school year. It’s amazing what three months can do to a person.
The best news is that I’ve figured out a way to revise the assignment so that it’ll be shorter as well as make it more effective. I worry, though, that this will remove some of the more creative submissions. I have to admit that I like how some of my students see themselves on an epic journey.
