A Good Read

There’s a certain cargo cult associated with these sorts of correlations.
If there are more than 3 or 4 variables that have an influence on something, we very quickly lose our ability to say anything meaningful about the situation. It’s true in health, the environment, and it’s also true in Education.
Knowing that the technique is terribly flawed and asking yourself—which you shouldn’t have to do because you ought to be told by the journalist what generated these data—if the study is subject to self-selection effects or confounded variable effects, and if it is, you should probably ignore them. What I most want to do is blow the whistle on this and stop scientists from doing this kind of thing. As I say, many of the very best social psychologists don’t understand this point.

Doodling in Class to Help Attention.

Approximate Reading Time: 2 minutes

Let your students doodle in class. Encourage them to doodle in class. You might be surprised at the result.

I have a one-hour commute to and from school, and lately I’ve been listening to the radio (CBC) rather than music. I noticed that I have a much easier time paying attention to the radio when I’m driving than when I’m at home. I thought it might have something to do with the fact that I a part of my brain is preoccupied with driving, freeing up another part to listen to the radio. I’m currently teaching an Intro to Computers class and there’s a regular series on CBC called Spark that features interesting tech-related stories. The one I happened to be listening to was about how we are “so connected, we’re disconnected“.

I wanted to have my class listen to this, but I knew they wouldn’t pay attention if I simply played it in class, so I decided to turn it into an exercise. I couldn’t have them all go for a drive, so I decided to have them doodle in class. I remember getting into trouble regularly when I was in grade school for doodling. I always had the sense that it helped keep me occupied in an otherwise boring class, so I thought it was worth a try. They were going to have to put away all of their devices (phone, computer, etc.) and I would give them a piece of paper to draw on. Because I wanted to make it clear that I was not actually expecting them to take notes, I used a blank piece of legal sized paper (so it would look and feel different from what they are used to), AND to move it even farther out of the norm for them, I decided I would give each student one crayon to use for their doodling. Just one crayon – I didn’t want them spending time thinking about what colour to make things – just doodle.

The result was really quite wonderful. After the session was over, I collected and laid out their doodles for everyone else to see. It was really fun to see what they had produced. Even more fun was the reaction from the students – they really liked it and more than a few commented on how the doodling helped them to listen.

Imagine my surprise when this comes across my feed:

Schools are teaching sketchnoting as an innovative way to help students synthesize information that’s important. Doodlers are making connections from what they hear to what they draw.

I plan on doing this exercise again. In fact, I’m even thinking about having several designated “No Tech” days throughout the term. I’m not ready to completely ban tech in the class. I think that’s going overboard and besides, it seems pretty hypocritical in an Intro to Computers class.

I’m starting to wonder if perhaps this tech generation has been deprived of learning how to “be” without their devices. I plan on giving them some opportunities to learn, and just maybe a few will realize there can be value in attention. Most people aren’t nearly as good at multi-tasking as they think they are.

Being a Woman in Computer Science – A Cautionary Tale, Part 3 of 3, Now

Approximate Reading Time: < 1 minute

A1LWMN97 This is the conclusion of yesterday’s post. It picks up where the other left off, after I was driven out of my position at the University.

It took a long time to come to terms with what was done to me. I think the fact that I was in the final stages of completing my PhD kept me from completely falling apart – although in truth there were times before I quit when it was touch and go. I know this would please those who were happy to see me go, but they say happiness is the best revenge, and I can honestly say I am happier doing what I do now than I think I would have been had I not been driven out.

I began to publish a lot more work after I left and now have a pretty solid publication record. I even won an award as a grad student for my research from the very same university that drove me out. How’s that for ironic? This is a university that claims to value research and innovation. I also started this blog.

I’ve moved on. I don’t actually want to do “regular” computer science anymore. I’m still heavily involved in tech, but although I still consider myself to be a computer scientist, I no longer feel comfortable saying it out loud.

Being a Woman in Computer Science – A Cautionary Tale, Part 2 of 3, Working in the Field

Approximate Reading Time: 5 minutes

 This is a continuation of yesterday’s post. It picks up where the other left off, at the end of my student days.

I defended my Master’s Thesis and just continued on where I was.1983-078

My thesis examined the introductory CS curriculum in an effort to define what it was and identify tools that could be used to help teach that. Even though I designed a built a number of the tools I proposed, I still got flack for doing a thesis that wasn’t hard-core CS. My supervisor quit the university half-way through my studies and so I had to switch. I ended up with a pretty tough committee for my defense – my new supervisor was also the department head and wanted to make sure there would be no question about my earning my degree. I guess in retrospect, I have to wonder if I had had the same level of scrutiny if I had been a guy. I know for a fact that there were a number of mediocre theses that got accepted around that time.

It was a great time to be in CS and I’d had several job offers before I graduated. I wasn’t even looking. Companies would come to us to recruit. In the end I took a position as an instructor in the very same department where I had just graduated. Calgary was my home, and I had loved my student years so much, I really didn’t want them to end. Plus, I had discovered that I was a pretty good teacher and I liked teaching.

Then I got Pregnant.

While some of the faculty continued to treat me as they always had, a number of them simply assumed that getting pregnant meant the end of my computer science career. It was odd for anyone to ask me about my plans. It bothered me at the time, but starting my family was more exciting than stressing about the attitudes of my colleagues.

I became a Part-Time Sessional

I took a year off with each of my children. Because I was a sessional, that meant I got NO benefits. I wasn’t even eligible for unemployment insurance.

I did do some consulting along the way. I remember one consulting gig where I mostly worked after regular business hours so I could bring my then 5-month old son with me. I have fond memories of sitting at a workstation with my baby beside me, and of trying to type while breast-feeding. The place I consulted for never complained – in fact they continued to hire me on and off for many years.

From the time my first child was born in 1984 to the time my youngest was four, I only ever worked part-time. It was a decision my husband and I BOTH made because we felt it was important to raise our children rather than to let some daycare do it. I realize that some people have no choice but to work, but as far as I’m concerned, if you have a choice, and you decide to leave your children in someone else’s care for 80% of their childhood then you are not doing right by your kids. I know this is an unpopular position to take these days, but children are far too important to let strangers have more influence on them than you do. Leaving them with family members is different. I fully realized what that would mean to my career, but that is the price of having a family. You can’t have it both ways. We decided I would be the one to stay home primarily because I had less earning power. It was in large part an economic decision.

Eventually, I started to teach full-time again.

1998-005_wmAlthough I began to work full-time again in 1998, my department head was considerate enough to make sure that I only had classes two or three days a week. That meant I could work from home the other days. My older two children were in school full-time, but my youngest wasn’t in school yet. My and my husband’s schedules (he’s an academic too) meant that our youngest would only be in daycare three days a week. The academic schedules and responsibilities were very important to our being able to spend time with our children. I know many people like to talk about “quality time” with children. “Quality time” is a lie. When it comes to children, they need TIME. Lots of time. I’m not sure we would have had this option if we had had full-time ‘regular’ jobs.

When I became full-time, I took on the role of 1st Year Coordinator in 1998. It involved a complete re-design of the first year program as well as managing all the teaching assistants, which during the peak years totaled 22 people. The first year program became one that encouraged a lot of students to continue on. It was a great program and I was quite proud of it. The fact that I was a girl though was rarely far from people’s consciousness. I had a dept head who, while supportive, insisted on calling me “Little Lady” or “Gal”. I also had to fight to get ‘promoted’ to full-time instructor from sessional.

It was really great for a while – LOVED it.

Then we got a new department head, and things started to change.

Leadership is everything, and organizations invariably go the way of their leaders. This one changed the entire culture of the department. There were many changes, not the least of which was that students were no longer welcome in ‘faculty’ areas. In particular, undergrads were left in the ‘old’ building, while faculty and grad students moved into a brand new building.

2003-beckerfunivcalgary-003_wmI stayed behind in the old building because I wanted to remain accessible to my students. While I considered myself a computer scientist, it was teaching that I really found fulfilling.

The more competent and confident I became, the more push-back I got from the dept head and his pals – including most of the other women faculty. Those who didn’t actively support the head in his efforts to make my life miserable simply kept quiet. I discovered that some of the people I had been calling ‘friend’ for as much as 25 years, actually weren’t.

Curiously most of the women faculty in the department were among the most hostile towards me.

In 2003, I became a student again.

ac-009I applied to the PhD program in the Education Faculty. I didn’t quit my job – I was going to do my PhD by studying part-time. I also applied for a sabbatical as I had been full-time faculty long enough to qualify. I was told by my Dean that I could not use my sabbatical to do any work on my PhD. Since my PhD was going to be in Education, it wasn’t of value to the Faculty of Science.

How’s that for support?

Also, due to the extremely stingy university policies – I had to pay FULL tuition – at the SAME school where I was tenured. Makes you feel all grateful and wanted, no?

I applied for and was granted tenure in 2003 before starting on my PhD. By that time pretty much everything I had built in the department to help and support undergraduate students has been dismantled, and my department head was so hostile towards everything I did that I had to get someone else (a former department head) to serve on my tenure committee in place of the department head in order to get a fair assessment.

I won’t go into all of the details (partly because of a gag order, and partly because it’s still too painful), but the end result was that I gave up my tenure. I quit.

I quit a job I had loved for 23 years, and left a place that was more my home than any other home had ever been. I had had an office on the second floor of the Math Sciences building from 1978 – 2006. I was there when I moved out of my parents’ house, when I met, moved in with, and married my husband. I was there through the births of all of my children, our move from the city to the country, and from the country to a farm. It had been my family my entire adult life and they had driven me out.

It almost killed me. THEY almost killed me.

But….. I’m still here, and there’s an epilogue to the story. I’ll tell you that tomorrow.

Being a Woman in Computer Science – A Cautionary Tale, Part 1 of 3, The Student Years

Approximate Reading Time: 6 minutes

I no longer consider myself to “in” computer science, although I will always consider myself both an academic and a computer scientist.

(There’s an older version of part of this story here.)

A1LWMNA0I grew up at a time when women TV role models were primarily women who’s job consisted of looking after their husband. We had shows like “I Dream of Jeannie” and “Bewitched“, and although I recognize their subversive non-compliance now, I don’t think I did when I was a kid. Of course, we also had shows like “The Avengers“, and Emma Peel was an important role model for me. I even got beat up once by Bradley, the neighbourhood bully while pretending to fight like Emma Peel. That’s when I realized that pretending to have martial arts fighting skills wasn’t the same as actually having them.

Fast-forward to my university student days. In the last post, I talked about how I go IN to computer science, and although I owe my career in no small part to the friends an mentors who supported me, I should also add that my own determination combined with an ability to ignore things helped a great deal.

I got into CS when I was 19.

Me with my brother shortly before starting university.

Me with my brother shortly before starting university.

I was quite pretty in those days and rarely had any trouble getting guys to ask me out. In fact, it was rare for me to become friends with a guy who didn’t ask me out.

That also included people I worked with and people I worked for. When I got my first job out of high school working at the Calgary Humane Society, it included the “Special Constable” in charge of complaints who used to like coming in on Sundays when I was working alone. He liked to sneak up behind me, wrap his arms around me and tell me he’d always wanted to be a cross-your-heart bra. He was a big guy, and I was only 16 (yes, I graduate high school when I was 16), so I would just smile and try to squirm away. It also included the owner of the gas station / sporting goods store where I worked after that who fired me for having a ‘bad attitude’. Apparently, refusing to sleep with your short, fat, old boss constitutes a bad attitude. It also included a long list of co-workers – married and not – who would occasionally ask me out or just corner me in the back room of whatever place I was working. I knew it was wrong, but I also knew it was futile to say anything about it. (I’m so glad things are changing in that regard.)

Back to my student days. Given what I was used to out in the “real” world, the kinds of harassment I faced once I was a student was mild by comparison. At least none of the TA’s ever tried to corner me anywhere, and many of them actually treated me with a fair amount of respect, as did most of the faculty. Of course, there was that one professor who called me into his office one time and closed the door. I’d had him for a class the previous semester, so I did kind of know him. The reason he closed the door, he said, was that he wanted to offer me a job, and he didn’t want anyone else to overhear. This professor told me he traveled a lot and gave many talks. He was looking for an assistant. He was actually kind of polite about the whole thing, but I figured out pretty fast that what he was really looking for was an “Assistant” – you know, someone to help him with lots of OTHER things too.
I said no thanks.
Fortunately, by that time, I was already pretty comfortable talking to my department head (he was one of my mentors), and I asked him about this “deal”. He seemed quite well aware of this professor’s antics. He’d never been called on it, and he wasn’t called on it this time either. We just all continued on as if nothing had happened.

CMBIZ078I’d never used a computer before I started university.

I didn’t plan on going into CS. I was going to become an ethologist. Jane Goodall was my role model (still is). I had no plans to continue school beyond my B.Sc.

Around the time I took my first CS course, I was beginning to realize that my chances of doing what I wanted to do with a Biology degree were slim to none. Probably the closest I could come was to be a park ranger, and that didn’t sound fulfilling to me, so I started considering other majors. I took a Psych course and was smitten, but then I took a subsequent course on motivation and lost all of mine. I also took a Geology course. The instructor was fantastic, and I considered becoming a geologist. That summer I worked for an oil company. I spent most of the summer colouring maps and it wasn’t until the last two weeks that I got to try my hand at plotting well-logs. That was fun, but I still couldn’t see myself doing that sort of thing for the rest of my life.

I had actually had me very first experience with a computer (EVER) in a Physics class as part of a lab. We were to run a simulation of a spring. There’s more on that part of the story here.

I became a TA when I was in the 2nd year of my undergraduate degree.

This was very important. This was a monumental thing for me. I’m an introvert and I was always painfully shy in front of crowds – any time I had to give a lab report in biology, I would stutter, my hands would shake, my face got all read and my eyes would start to water. It was awful! And that was when I was allowed to sit at my lab bench and only had to present my report to 5 other people. I’m sure at least some of this came from the fact that I was often picked on and made fun of in school. I was accelerated in grade two (It’s worth noting here that my male principal took six girls and put them in an accelerated program because he thought we were all exceptionally bright. There were no boys in this program.) As a result, I ended up being a good two years younger than my classmates for the rest of my school career – I don’t recommend it. I also got very sick the summer after my dad died and ended up missing a lot of school in high school. It made me stand out, and not in a good way.

Back to university. Here I was in a group of people who thought I could teach a class. I’m sure their confidence in me had a lot to do with my ultimately becoming a CS instructor, and even though the thought of standing at the head of a class terrified me, I tried to remember that even though I didn’t know much, I DID know more than the people in the lab I was teaching, and I would do what I could to help them learn what I knew.

I’ve heard it said that the best way to learn something is to teach it.

My most important course was “Coffee Lounge”.

The CS department where I was taking courses was VERY friendly and welcoming. Faculty, grad students, and undergrads were all part of the same community. This was before the Internet allowed people to work at a distance so everyone had to do their work on campus, in the labs. There was a grad student workroom where grad students AND faculty worked. The door was usually open. There was also a big ‘terminal’ room filled with dumb terminals (a technical term, not an insult) that were connected to mainframes housed in the basement.

We spent a lot of time together. We socialized together. We went to dinner together and had parties together. The department hosted an End of Term party twice a year – paid for by the faculty, and all students were invited – including undergrads. AND, the faculty coffee lounge was always open. I would often go in there, initially with a grad student, but then also by myself. I’d get a coffee (I never paid for it – and was never asked to) and just sit and listen. There were often several faculty members sitting in there having some sort of discussion, and it was more often than not something to do with CS.

I probably logged more hours in that room than I did in any other course I took, and I’m pretty sure I learned more there too. No exams, no assignments, just people passionate and excited about their field having conversations, and sometimes arguments.

I went straight into a master’s after graduating with my BSc.

1981-jnk_wm1981-katrin-81-1I also got married at that time – to one of the guys who had been instrumental in my getting into CS. Because I was already so much a part of the department by the time I got into the masters program, I really didn’t notice much difference.

My years as a student were among the best times of my life, and as an instructor I have always tried to foster the same kind of culture and environment with my students.

More on that in tomorrow’s post.

How I Got Into Computer Science (Many Happy Years)

Approximate Reading Time: 3 minutes

Next week I am meeting with a bunch of young women in our department‘s CS and CIS programs, so I’ve been thinking about how I got into computer science, and why I stayed.

Here’s my tale of how I got into CS.

I’ve been at it for a while now. I did my first degrees in the late 1970s and early 1980s.

snap02112

There were regular Faculty/Grad Student sports events.

The CS department where I did my undergrad was still pretty new, and was a place full of incredible enthusiasm. They were very collegial and had a lot fun. This created a real sense of community, and they shared it freely with graduate students and undergrads alike. That was key. They included me like I was one of them right from the very first course that I took. The sense of community was one of the most important factors for me, perhaps because I had so rarely been a part of a community in any school I’d been to before.

snap02114

There were also frequent practical jokes – often played on faculty while they were teaching a class.

Most of the women faculty that I knew in CS were not viable role models*, but it didn’t seem to matter. There were a number of female grad students, and many of them were pretty good role models.

I had viable male role models – and they seemed not to be put off by the fact that I was female – some even LIKED that I was – they made me feel female & desirable AND they made me feel that my intelligence and ability was part of that. None of them seemed to have much time for pretty and dumb, so, after several years in retail (where pretty was really all that mattered), this was a refreshing – and inspiring change.

Some of the faculty were very important role models for me – not only for how to be a computer scientists, but also for how to be an academic. There were also three others who were instrumental in my decision to go into computer science. Understand that I took my first CS course in 1977. I am still in contact with all three. I married one (and I’m still married to him). These were the first guys my age who ever treated me like I was smart. Even weirder – they actually liked the fact that I was smart. The grad student who was my TA in my very first CS class went out of his way to tell me he thought I was good at this. Now, this guy was known as somewhat of a curmudgeon – and one not to suffer fools gladly, so when he told me I had potential, it really meant something.

I had already decided that I liked programming. For me, programming seemed to have a lot to do with sorting and organizing – activities I have always enjoyed. That, and the friendship, support, and confidence of these people were why I got into CS. They are also the reasons I stayed. In the end though I’m pretty sure that if it hadn’t been for the people around me, I would not have made it.

So, forgive me if I forget anyone, but let me end this by thanking the people who are in no small part responsible for my going into CS, and for the many happy years I had while there:

Jim Parker, Neal Reid, Bob Bramwell, David Scroth, Anton Colijn, Mike Williams, Harry Baecker, John Slater, Bill Pulleyblank, and Doug Robinson.

There are plenty of others who were great mentors and friends – many of whom I am still in contact with – but the ones named above are my top 10. I wouldn’t be here without you!


*I have never had much time for strident women who raise themselves up by putting men (or others) down, AND I have little respect for women who feel the need to hide their femaleness (by being frumpy or vulgar). We need to get past the notion that women need to be men in order to make it. Now, truth be told, this is an attitude I have only managed to embrace in more recent years. While I was young, I was willing to compromise on many fronts in order to get the recognition/respect I felt I deserved, so I will not fault young women who do the same. One thing I found was that the more I began to act true to myself in my department, the more people attacked me – especially the women (but more on that in the Why I Got Out post).
