Long ago (1988) I moved to Berkeley and started sending a monthly "newsletter" to my Boston friends. When I returned to Boston (1993), I continued the tradition for about five more years (or until I had kids). Looking back, I realize that I was actually blogging. Each newsletter contained anywhere from a few to several blog posts. Having been silent for the past decade or so, I've decided to resume these activities. Don't expect anything profound -- I tend to focus on what I find entertaining or amusing and perhaps sometimes informative. We shall see!

Chasing Mia

This posting was written several weeks ago, but I was in the midst of my flipping sequence and didn't want to break that up, so I delayed posting this one.

As an admitted groupie of the US Women's National soccer team and a Meadowbrook parent, two unrelated postings make me want to write.

As this year's soccer season began for the women's national team, I struggled with the emotional conflict I felt as I prepared to watch Abby Wamback overtake Mia Hamm's goal-scoring record. (I predicted last year it would happen during the Algarve cup and I was wrong, but it will certainly happen this year.) Then, the head of our Middle School wrote a nice piece about why Meadowbrook gives out Spirit Cups for their sports teams.

I have always watched in stunned disbelief as the media and most of our society turn atheletes into role models. Just because someone is good at riding a bicycle (quickly) or throwing a ball into a hoop, why do we immediately assume that they are people our kids should emulate? At the same time, year after year, I look at the women who play for our US team, and I think, "Now there are role models!" These are nearly uniformly amazing women who have dedicated themselves to an underappreciated and underpaying sport. They work hard on the field and off the field, reaching out to fans, working with young people, and dedicating themselves to important causes, without a lot of fanfare, without the trappings of superstardom, and without the negative actions that draw negative publicity. I can hear some of you, "Oh, they are just women soccer players." No, they are world-class professional atheletes. They are among the absolute best in the world at what they do. And they do it in a sport that is important to more of the world than any of our conventional American pasttimes.

At the risk of missing someone deserving, let me run through the list of past and present US Women's National Team players who are extraordinary individuals as well as extraordinary atheletes.

  • Joy Fawcett, thank you for embracing your professional atheleticism and motherhood simultaneously, for showing us that the two are not mutually exclusive, that you can bring your kids to work and still perform at the highest levels.
  • Michelle Akers, thank you for showing us what it means to give your all -- through illness, injury, and perhaps even beyond the point of what was good for you personally, you gave every last bit of yourself on the field.
  • Heather O'Reilly, thank you for showing us what a work ethic is. In every minute of every game that you play, you are 100% engaged on the field, chasing down every last ball or player.
  • Amy Rodriguez, thank you for being approachable, for understanding that just talking with and teasing the young people who admire you makes them feel special.
  • Carli Lloyd, thank you for helping me never question whether I'd play soccer again after breaking my ankle. As I rehabbed, I watched you rehab. As you returned to the national team, I knew I too would return to my (not quite so competitive) team.
  • Shannon Boxx, thank you for demonstrating the importance of having a professional league in this country.
  • Cat Whitehill, thank you for seeing into the heart and soul of a recreational soccer team and treating them with the same respect you gave your national teammates.
  • Brianna Scurry, thank you for always demanding the best, for handling difficult situations with grace, and of course, for stopping PKs!
  • Tiffany Milbrett, thank you for making me proud to wear #16.
  • Kristine Lilly, thank you for many things -- for redefining what age means in soccer, for demonstrating what commitment and passion really are, and for showing the world that it's not only OK, but good for women to wield power.
and now, back to where we started:
  • Thank you Abby -- for everything -- for the role that's been thrust upon you as the bridge between the past and the future. More than anyone else, you have been the transition between "the 91ers" and the future of US Women's soccer. You have provided leadership through both good and challenging times; you graciously accepted the mentoring of your predecessors and pass that on to your successors. And, thank you for putting Rochester on the map!
  • Last, but never least, thank you Mia -- for becoming the face of women's soccer, although it seemed you would have always preferred not to be in the limelight. Women's soccer needed a superstar, a spokeswoman, an idol. You showed us that teamwork was as important as personal performance by wracking up almost as many assists as you did goals (144 to 158). Regardless of whose name appears in what categories in the record books, you will always be Mia -- the first face of women's soccer in this country.

Flipping Over

We are done. The course is over, except for the data analysis, which I expect to entertain me over the summer. This last entry will be a collection of random topics - things that happened over the course of the final exam and grading or observations I've made.

End of year party

Long ago, in 1993, we started the tradition of having an ice cream bash after the take home final. I don't believe we've maintained the tradition, but I decided to resurrect it. In addition, we continued the tradition of class T-shirts. The winning design was:

In addition, since I had artwork for each group, I made that available to students to construct their own team patch, which they could then iron onto their shirts. Groups who didn't have the time to do anything fancy (21 of 22 groups), got the plain hand-drawn black and white animal.

So, on Wednesday afternoon after spending a lot of time on the final, we all gathered in a much too small room to eat Toscanini's ice cream, collect T-shirts, and iron on patches. It was a total blast. Pretty much everyone ironed their patches. The one group who augmented their animal was the marmots, who added color and appropriate attire:

We had a few ironing disasters which prompted a return to QRSTs for a few additional shirts.

Had I been thinking, I would have tried to get a group shot, but I didn't. Next time! One of my students, did take this small group picture:

Students seemed relatively happy and relaxed, although a few still had multiple final projects to complete. Much ice cream was consumed. The pear chardonnay sorbet was not consumed, but I have to say, it was outstanding (it came home and disappeared stunningly quickly). It was a good end to the course!

The final

For the curious, here is the final exam. I thought it was pretty tough; it was certainly time consuming to grade (it took me the better part of a week to grade 45 exams -- I'm guessing over an hour per exam). The students did exceptionally well -- a typical Margo-exam ends up with a median around 67%; this one had a median and mean over 80%!

The first problem was a design exercise and those are notoriously difficult to grade; after two days of grading I wondered why I continued to give these kinds of questions. Then a colleague, Kryzstof Gajos, explained how we graded his final exam, and I am excited to contemplate how I can apply this technique. I've invited him to write a guest entry on the topic, but in the meantime, here is my understanding.

The course he was teaching is called CS 179: Design of Usable Interactive Systems. It is very much a course all about design. So for the final exam, he split the period into two parts. During the first part, students took the (written) exam using a "uniquely" colored pen (provided by Professor Gajos). Then, he collected the pens and the class collectively graded (their own) exams. Thus, in real time, the class discussed the problems, the supposedly right answers, alternative answers, etc. When there was ambiguity, they discussed it. Afterwards, he collected the exams, had the TFs check that the self-grading was accurate and he was done.

This was pure brilliance! I'm not saying that because it reduces grading time (which it does), but because it turns a purely summative evaluation process and makes it partially formative. I try to do this when I grade exams -- I essentially engage in a typewritten discussion about their answers (which is one reason exams take so long to grade). I always have second thoughts about this, because I know that students merely search for the final number and ignore everything I write. Or so I thought (more on this later). The idea of discussing the exam right after they've finished it and being able to address confusion immediately is overwhelmingly appealing to me. It's not entirely clear how to apply this to my exam -- I like pushing students to think about complex issues for which mulling the ideas and questions over is useful (this is why I like the takehome exam format). I don't know how I'd fit both the testing and the grading into a standard 3-hour test slot. If I stick with the 24-hour format, then I'd have to make the exam be, say, a 20 hour exam with a scheduled 2-hour class which sounds like a logistic nightmare. I'm not sure what I'm going to do here, but I see further experimentation in my future.

In addition to a design question, I asked people to read a research paper ( the Barrelfish SOSP paper), and then I asked them questions on it. I'm really looking forward to having some of these students in my graduate OS class, because the high bar they set for a system is quite interesting. Many were accepting of a prototype, but a surprising number took a more business perspective, while perhaps not appropriate for a research paper, indicated to me a much better sense of how the world works than many tech-savvy people are. I found it fascinating.

In another question, I asked them to respond to a (rather poor) technical suggestion, but I asked them to do it in the context of an email to an engineer who worked for them (I put the students in the role of being the project architect). I was quite impressed with the care most students took in crafting a reply that was both technically correct as well as polite.

The post final

Although I write fairly long comments on my students' exams, I know deep inside that they never read them, and yet I continue to do it, because I know that there is the potential for learning there. This year, I was pleasantly surprised -- for the first time in twenty years, I had a couple of people engage with me after the exam to discuss answers. They weren't looking for points but were instead, trying to make sure they understood what a right answer to a few questions would look like. In one case, a student wrote up about 5-6 paragraphs as an answer to one problem to make sure that the student had a complete grasp on the answer. I was (pleasantly) astonished. While I can't make any causal statements between new pedagogy and this behavior, I could certainly believe that because I am much more closely engaged with students, they felt more comfortable doing this. In any case, I was quite pleased.

The end

And so, one woman's adventure with flipping comes to an end. I'm looking forward to crunching data, and I'll certainly post here if/when I find something interesting to say. In the meantime, here are my parting thoughts.
  • It's good for an old dog to learn new tricks.
  • Flipping lets me spend time with those students for whom the material is challenging.
  • Learning takes place by doing, not by listening to me.
  • TF engagement is critical.
  • It takes a lot of effort to come up with effective in-class work.
  • Pre class web forms are AWESOME. They let me engage with students in an entirely different way and to gather lots of interesting data.
  • CS161 is even more time intensive than I thought.
  • It would be useful to help students learn what it really means to design something.
  • Flipping is a great equalizer when students enter with different experience levels or exposure to different topics.
  • Fully integrated and coordinated materials take real effort but pay off tremendously.
