Knowing that this year would be crazy busy for me, I chose my service wisely. I tried to select things that were staggered throughout the year, so that I could give my time and attention to them without stressing out too much. I tried to avoid January and February since that’s when hiring season will kick into high gear around here. I said no to some opportunities because I knew I wouldn’t have the bandwidth for them.
Even with all this careful planning, several of my service activities are now ramping up all at the same time, and all of them seem to require attention at precisely the same times.
So much for careful planning, huh.

This term, I’m experimenting with all-electronic grading. I’ve always felt a bit squicky about all the paper involved in take-home exams and essays. But I’ve felt more comfortable grading on paper, so even when students turn in take-home exams or essays on Moodle, I tend to print them out to grade them. Moodle introduced a blind grading feature recently, and with this feature I decided to try and go all-electronic.
My system goes like this: Students turn in exams or essays in either Word or PDF format. If they turn in a Word file, I use track changes to make comments and/or indicate how many points they received on a question. If they turn in a PDF file, I use the annotation features in Preview to make comments, mark up the text, highlight passages, etc. Usually I also have an associated rubric on Moodle, but since I comment on their papers/exams directly I just refer them to the document for comments rather than repeating them in the rubric.
I was worried about the clunkiness of this, particularly with annotating PDFs. But I’ve been annotating PDFs I read for research for quite some time now (also to save paper), so I’ve gotten used to how to annotate in Preview and I have a pretty good workflow. And I’m actually enjoying it quite a bit. I can copy and paste comments between papers/exams (good when many students miss the same question or make the same mistake for the same reasons). I had all of my Networks exams open on my computer earlier, and I found it easy to switch back and forth between them, allowing me to grade like I normally do (one part of a question at a time for each student in the class). I find I make longer and more constructive comments and it takes me less time.
Interestingly, my Networks class appears to favor PDFs while my freshman seminar definitely favors Word docs. I’m not sure why this is.

Tomorrow I embark on a new-to-me adventure. I’m serving as an external reviewer for a CS department review at another liberal arts institution.
I’m pretty excited about the opportunity. We went through our own department review a few years back (right after we brought our son home), but since I was on leave I had a pretty fractured view of the process. I am looking forward to meeting new people, talking about trends in the field, and seeing how another institution does things.
That said, the schedule for this thing looks pretty daunting! I am an extrovert and usually thrive on interacting with people, but I’m thinking I will need to sit and stare at a wall for a few hours after I get back to my hotel, especially at the end of the first full day. I know that the schedule has to be this way due to the short time frame, but ay caramba, this will test my extrovertedness for sure.
One of the top things on my mind since taking over as department chair is culture: specifically, department culture. As chair, I set the tone for the department in various ways. I set the tone when I set the agenda for a department meeting or retreat: the topics I select, and the time I choose to devote to each, signals how much of a priority I think they are to the department. I set the tone when I interact with faculty and students, both new and returning. I set the tone when I represent the department at meetings and such, and when I advocate for the department to administrators and other campus offices and constituencies.
I’ve been thinking about this so much lately because the dynamics of our department are changing rapidly. We have a record number of majors (91 juniors and seniors at an institution of 2000 students) and a large number of non-majors who take or want to take our courses. We have two new full-time visiting faculty members and two part-time visiting faculty members to help us meet our course demand, which means we have almost equal numbers of visiting faculty (4) and tenure-track faculty (5). We’re conducting a tenure-track search this year to grow our department. We’re a little more balanced than we have been in terms of rank, with 2 full, 2 associate, and one tenure-track assistant prof, but the visitors definitely skew us younger. And perhaps the most challenging: we’re spread across 3 buildings, one of which is a 7-8 minute walk from the others.*
So what do I see as the main challenges to setting the tone of the department internally?
- Keeping everyone in the loop. Up until now, we’ve very much had a “hallway conversation” approach to decision-making. That is, a nontrivial number of department decisions, discussions, etc. happened as a result of spontaneous hallway conversations. This model can work okay when everyone’s physically on the same floor in the same building, but assumes that all stakeholders are present. Even last year when most of us were on the same floor, this model didn’t work well because inadvertently someone (usually staff) was left out and wondering what happened. With faculty physically in different places, this model ceases to work at all. I suspect changing this aspect of culture will be one of the most challenging, just because we’ve operated under it for so long that it’s second nature. But as someone traditionally on the outside of the field, I recognize the harm and bad feelings that result from being left out of important conversations, so I’ll be looking at creative ways to make sure everyone stays informed and involved, no matter where their offices are or what their rank is.
- Mentoring. We have so many young, early career faculty in the department! Most of our visitors likely have a tenure-track position at a similar institution as their long-term goal. Our tenure-track prof will be going up for tenure in a few years. I want to see all of them succeed. I want to make sure all of them have the tools to succeed. I want to make sure our tenure-track prof is doing all the right things to put her in a good position to earn tenure here, and I want to make sure as a department we’re giving her strong, consistent messages and useful, constructive feedback. I want the visitors to make the most of their time here, to learn as much as they can about teaching at an undergraduate institution, and to grow as teachers and scholars so that they put themselves in a great position to get hired on the tenure-track, here or elsewhere.
- The student experience. It’s unclear exactly why we have such a large uptick in majors and in enrollments generally. I tend to chalk it up to the fact that we, individually and as a department, are just awesome. Seriously, though, I think we as a department offer students interesting, challenging classroom and research experiences; we do a good job of making our courses relevant to students; we are also approachable and fun and genuinely interested in our students. We don’t provide high barriers to entry, and I think that’s key as well, maybe even more important than the rest: we teach the intro students where they are. Can we continue to do this with such high student-to-prof ratios? Will we see a drop in non-major enrollments given that none of us are advising non-majors anymore, since our major advising loads put us at the advising limit? How can we continue to connect with our students as individuals given our high class enrollments? Finally, how can we make sure we have adequate physical spaces, for classes and collaborations and just general hanging-out, to support the large numbers of students, particularly in a building not designed for such numbers?
- Balancing the proactive with the reactive. When a department grows and changes as rapidly as ours did, it’s easy to fall into “fire-fighting” mode, running from one crisis to the next. It’s really important to take and make time to step back and consider the larger picture, for the long-term health of the department and the major, but so hard to do when so many little things vie for your attention. But it’s also important to recognize the patterns in the little things that point out larger trends and lead to the larger discussions.
I don’t claim to know all the answers here, and most likely I’ll stumble and fumble as I try to make sense of the challenges, but I do look forward to the challenges and the opportunities as chair to address these. Hopefully I’ll get a handle on this sometime in the next 3 years, before my term is up!
* Those of you on large campuses are no doubt chuckling at this, but our campus is very compact, so a 7-8 minute walk is significant.
We’re halfway through our inaugural summer program for high school students. I am happy to report that I am surviving so far (some days, barely) and mostly having a great time.
I talked a bit about the program in a previous post, but to recap: 31 students, divided into 3 groups. Mornings are class time: each week they take one class for 3 hours each day in a different specialty (this year: human-computer interaction (HCI), robotics, and evolutionary computation), rotating among the specialties each week. In the afternoons, they do research with faculty. So I teach HCI for 3 hours every morning, and in the afternoon I have 11 students doing research with me in HCI. So far the program seems to be working rather well.
It was hard for me at first to figure out how to structure my course and research for the high schoolers. I have zero experience with high school students, so I went into this with more questions than answers. How much did they already know? How quickly could they learn? How would they compare intellectually to Carleton students? What could I realistically expect them to do research-wise in 3 weeks?
I decided to assume that these students would be on par with Carleton students (after all, these are students that we hope will come to Carleton), and structured my curriculum appropriately. I set up my class meetings similar to how I would set up a Carleton class (well, similar to 3 class meetings rolled into one day), with similar content and similar activities. I figured it would be easier to adjust down than adjust up if necessary. One major change: more lecturing, since I couldn’t count on them reading the appropriate material before class. I’m not totally comfortable with that aspect, but consider it a necessary evil.
The research was trickier. I wanted them to do actual research, as in research I’m actually working on right now. But I don’t have time to instruct them in all of the necessary background knowledge, and again, it was unclear to me how their backgrounds would translate into ability to contribute meaningfully to a research project. Also, as I’ve mentioned, my current project is brand-new and I don’t fully understand all aspects of it yet! I settled on having them create visualizations (via web pages) for some of the data we’re currently collecting, and presenting this data in a way that our target demographics would understand and that would teach them about how the system works. I figured they would be able to get at least something up and running by the end of the 3 weeks.
So, how is it going so far?
My instincts were correct for the classroom portion: intellectually, the students are on par with Carleton students. They are bright, engaged, and (mostly) delightfully wacky. They are doing the same level work in class, by and large, that my college students do. The one key difference: it is harder to keep them on task. So, for instance, my college students can typically stay on task for 25-30 minutes, whereas for the high schoolers it’s more like 10-15 minutes. This probably has something to do with different developmental stages. At any rate, as long as I factor this in to my daily class plan, I’m good.
Content-wise: well, it’s always hard to boil down an entire field into 15 hours of class instruction, but I think I did a good job for the most part selecting content. I’d definitely jettison some activities next time and refine others, and choose what to lecture about differently. The beauty of this program, though, is that I repeat the same class 3 times, so I have the opportunity this week to fix the things I didn’t like about how class went last week, and things are already going more smoothly.
The research portion is also going well. I made one major tactical mistake: I decided to give a brief overview of the computer networks portion of the research so that they could concentrate on the HCI aspect. By Thursday of last week, though, it was clear that my high school researchers were struggling in developing visualizations because they didn’t really understand what they were visualizing and why. So I spent all of our research time on Friday afternoon doing Networks 101 and giving a more detailed overview of the project. I told them they could ask any question, no matter how stupid they thought it was—and of course, there were no stupid questions and a ton of excellent questions. We covered a ton of ground, and by the end of the day they felt much more confident about what they were doing and why.
The other issue I’m facing is that I may have underestimated what they are capable of doing. Many are getting a little bored of the prototyping tool and so we decided they should learn HTML and actually code up the sites they’ve been prototyping. That’s been a big hit so far. Some of the groups may also end up doing some more with the raw data than I originally intended, which is also great. I had my undergraduate research students come in this afternoon and “consult” with each group, which I think both my high school students and my undergraduates enjoyed.
The whole experience has been fun and enriching and ultimately is helping me become a better teacher and better research mentor. That said, it is EXHAUSTING. This week is a bit better than last because the research is underway and I’m repeating last week’s curriculum, but it’s still very busy and very packed. Fitting all my other responsibilities, as chair and faculty member and research mentor, into these packed days has been quite the challenge. But at this point, even with the mental and physical exhaustion and the challenges, I would definitely do this again next year, and in fact am looking forward to doing this again next year.
For the past 9+ weeks, I’ve been following a training plan for the half-marathon I’m running 2 weeks from this coming Saturday. The training plan is a typical one: each week has 4 days of running. One of the 4 days involves speedwork: intervals, a tempo run (i.e. “run at this pace for this number of minutes”), or hill repeats (run up a hill fast, walk down, do it again and again). One of the days is a long run. The long run gets progressively longer, as does the speedwork, as the weeks go by. And the plan ends with a “taper” period: after you’ve spent all this time building up your mileage and endurance, you cut back and let your body rest before the big day.
There are no guarantees, of course: the plan doesn’t guarantee that you won’t get injured or sick, or that you won’t wake up the day of the race facing 95 degree temperatures and 100% humidity and have to throw your time goals out the window. Rather, the idea is that if you put in the work and follow the plan, you put yourself in the best possible position to finish the race and meet whatever other (usually finishing time) goals you have.
It is easy, particularly as race day looms, for you to get cynical and to doubt the plan. How can you really be prepared to run 13.1 miles if your longest training run is only 12 miles? Why aren’t the long runs done at the pace you intend to race at, but rather at a much slower pace? How on earth do 6×400 intervals prepare you to run at race pace? At some point, you just have to trust the process, to know that each piece of the plan each week contributes to your execution on race day, and to go with it.
Trusting the process is something that I do often as a professor. When I teach, I trust that if I’ve prepared properly—digging up and digesting background readings, developing illustrative examples, working through in-class activities, anticipating likely questions and points of confusion—then class is most likely going to go well. I can’t guarantee this, of course—my students might come ill-prepared, or bring low energy to the class, or an activity might bomb in unintended ways—but most often, everything will be fine. In research, unexpected twists and turns often pop up, but if I follow the plan—think carefully and methodically, locate and read the relevant literature, weigh the evidence carefully, analyze and reanalyze the data, be super-observant and dig deeper into the data—eventually I’ll succeed, even if “success” is not how I originally pictured or intended it.
In a way, trusting the process is similar to taking the long-range view while paying attention to the day-to-day details. If you think too hard about the long-term goal, it can seem impossible to obtain. But if you get too caught up in the day-to-day, you can easily get discouraged. When you trust the process, you do the day-to-day while keeping your attention on the long-term goal. One motivates the other.
Trusting the process is something that’s often difficult for new researchers. New researchers may not know or understand the long-term goal. They may get caught up in the day-to-day, and possibly even overwhelmed by it. They may not see how the day-to-day and all the small, sometimes seemingly inconsequential tasks, all work to contribute to the end goal. This can be particularly true of new projects, where perhaps the end goal is still a bit fuzzy or in flux. And teaching trust of the process is tricky, because at some point, the person just has to buy into the idea.
This is definitely happening in my lab this summer, with my brand-new project and new-to-research students. So how am I teaching trust in the process? I’m not sure if I’m doing it well or even passably at this point. What I try to do is remind my students of why we’re doing what we’re doing and continually framing the problem and the research. I do it by being specific about the small tasks we need to do to get there. I remind them of what we’ve done so far and how what we’re doing next both builds upon that and gets us closer to our end goal.
So far the trust is not completely there, but that’s ok. They are skeptical, but game. They ask lots of questions, including lots of variations on “so why are we doing this again?”, which is exactly what they should be asking. They’re starting to figure out the “next small thing” on their own. I may not get them all the way to trusting the process by the end of the summer, but if I can at least get them partway there, I’ll consider that a victory.
We’re still in session around these parts—our last day of classes for spring term is tomorrow, followed by reading days and exams, followed by the mad dash to get senior grades done 36 hours after the final projects come in…good times. This has been a particularly brutal term, work-wise and stress-wise, so I will be happy to see it end.
This week I’m juggling both wrapping-up-the-term activities and ramping-up-for-the-summer activities, which frankly is making my brain hurt. I’m ending the term like I started the term: frantic and behind on my work. I like to try and end each term on a strong note, but this year I am definitely exhausted mentally and physically and feel like I’m limping into the summer instead of leaping energetically and enthusiastically into the summer.
This summer’s workload will be substantial, with five major initiatives (just thinking about it all makes my head hurt even more!). Here’s what I’ll be spending my “lazy” summer “off” doing:
- Starting a new research project. I submitted a grant application late last year for a new project. I’m super-excited about the project: it combines my previous research on rich media and quality of experience with some network measurement, human-centered computing, and tool-building thrown in for good measure. But starting a new research project is always a bit daunting: what if it turns out this is a bad idea? what if we don’t get anywhere? where the hell do we start? And starting a new research project with students (see below) is doubly daunting. I have a vague plan of where to start, but frankly part of me is terrified. We could easily spend the entire summer just trying to get things up and running and still not have anything up or running at the end. I think the chances of that are small, but it’s enough to keep me up at night. At any rate, I’ll definitely be busting my ass this summer trying to get this project off the ground.
- Teaching in a brand new high school program. Because clearly starting a new research project from scratch is not enough excitement for one summer! Seriously though, Carleton is starting a new CS summer program this year for high school students for 3 weeks. We teach the students in the morning and work with a subset of them in the afternoon, in our research labs, on “real” CS research problems. I am very excited about this program, but know realistically that it will be a lot of work. We had our curriculum meeting today, so I’ve already done a bunch of planning for my classroom portion of the program, but still need to hammer out details about the research problems, as well as the software/programming language. Not to mention that the research problems, as I envision them at this point, rely heavily on progress we make on the new research project leading up to the high school program….yeah, there’s no way THIS could fail!
- Supervising 3 undergraduate research students. I took a hiatus last year from supervising students in my lab, mainly because I thought I’d be on parental leave, but this summer my lab will be full of students again. None of the students working for me have experience doing CS research, so my involvement will be very hands-on at the start of the summer. However, most of my former research students had no experience either, and things turned out well, and this group seems really eager and ready to get to work. (Plus I’ve been working with 2 of the 3 of them this term.) The one worrisome part is the new students + new project combination. I think I just need to go in with a flexible mindset and plans B-Z if things go awry. Again, what could possibly go wrong?
- Taking over as department chair July 1. And just like that, my service commitments increase exponentially. My big tasks out of the gate will be getting the agenda together for the department retreat in August and sketching out job ads for our tenure track search—and, of course, figuring out how to be department chair.
- Planning a brand new course for the fall. I’ve always wanted to teach a human-computer interaction (HCI) course. I sort of did so with the dyad a couple of years back, but this time around I’ll be teaching an A&I (freshman) seminar on the topic. I’m wildly excited about this opportunity, but (a) this is not my area and (b) we don’t have a senior-level class which I can raid for ideas. I met with some great people at SIGCSE this year who gave me some great teaching and course construction ideas, and my high school course in the summer program is on HCI, so I’m not completely starting from scratch. Still, this should be quite the adventure. (And did I mention that by definition this is a writing-rich course? Yikes!)
In addition, I have some assessment tasks to wrap up in July before handing over the assessment reins, and organizing our contingent for Grace Hopper will of course take place throughout the summer. And did I mention I’m running a half marathon in early August?
The good news is, with the exception of #4, everything on my plate this summer is fun-to-me and exciting and intellectually stimulating. Yes, I’ll be working hard, but it’s all on things I’ll enjoy immensely. So that definitely makes things a bit less daunting. That said, my goal is to get through the summer sustainably, without burning myself out….because I’m really going to need to be fresh and well-rested and renewed before the absolute insanity that will be my next academic year.
- We’ve now officially reached the point in the term/school year where there is no schedule—there is just running from one crisis to another. I am too tired for planning anything beyond the next half hour.
- Signs your job might be adversely affecting your family life: You joke about quitting and your spouse says “can you? really? please?”. Uh-oh….
- Everyone (neighbors, day care parents, random people on the streets) keeps asking me when my summer starts. This is the problem with the term system: we have 3 more weeks of classes. Heck, I just finished grading midterms! This is the tradeoff with terms: August is awesome, May stinks.
- 2/3 of the readings in my Software Design class have been, well, let’s say not your typical textbook readings.* The tone is easy and conversational and a bit irreverent, but the content is still pretty hefty. Which is why I chose these readings—they get all the important points across in an engaging but nontrivial way. What I’m finding interesting, though, is how the students are reacting to these readings. A few off-hand comments and questions from a few students indicate that the tone obscures the fact that there’s quite a bit of substance there. This is especially true of the web usability reading. Next time I teach this course, I will make a more conscious effort to point out the theory behind the readings, but it’s been an interesting lesson.
- We are not quite there yet, but someday (someday!) I will not find it remarkable that I have an all-female final project group.
- Officially I don’t become department chair until July 1, but it’s kind of already started for me. Students have started coming to me asking all sorts of complicated questions about graduation and major requirements and special cases. I have a hiring meeting w/ some deans later this week. I’m already getting all manner of chair-related emails (particularly about budgets). I’ve started thinking about all sorts of processes and agendas and such. I’m glad for this transition time, but at the same time part of me is like IT’S TOO SOON! AAAARRRRGGHH!
- One particular chair-related issue that’s keeping me up at night: We have 57 newly-declared CS majors. Yes, you read that number right. I’ll wait for you to pick yourself off the floor…. So, we need to put all these majors in project teams for Comps in 2014-15. How do we do this without completely overwhelming our faculty resources? Great question. Let me know if you figure it out.
- Next week I’ll be at the NCWIT summit in Tucson. I look forward to the Summit every year (look for live tweets again!)—I always learn a whole bunch of new things, and it’s a great excuse to see the people I see at Grace Hopper and/or SIGCSE again (there is a lot of overlap in those crowds). This year I’ll be running a session in the Academic Alliance meeting along w/ my other team leaders. I’m excited—we have a great plan and great panelists lined up—but also nervous because part of our session involves a software demo. Trying not to panic about the many things that could and might go wrong there…yikes!
* Krug’s Don’t Make Me Think! and Freeman/Freeman/Sierra/Bates’ Head First Design Patterns
This term I am teaching in Carleton’s “interactive classroom”, more commonly referred to as the Sandbox. This is my first time teaching in this particular classroom, although I’ve admired it from afar since it opened for business in 2011.
The classroom is set up for collaboration. It’s a long, narrow room with 8 round tables, 6 chairs per table. Each table has a microphone, a large wall-mounted monitor, and a hookup to the projection system so that students can hook their laptops, etc to the monitor. (As the instructor, I can theoretically project this input onto the projection screen too, although I haven’t tried to do that yet.) The room also has whiteboards on 3 of the 4 walls (the 4th, narrow wall has windows), allowing each table access to plenty of drawing/scribbling space. There’s a teaching station in the middle of the room which also hooks up into the room’s projection system.
The setup of this room is perfect for the type of class I’m teaching. My class, Software Design, focuses on the art and science and practical aspects of programming, design, and development. It’s the perfect class for flipping, since much of the content is best covered by doing and not by telling. It’s also the perfect class for collaboration of all sorts: small group discussions, code reviews, design critiques, etc.
So, now that we’re five weeks in, how is the classroom working out? Is it everything I envisioned it would be and more? Or am I desperately wishing for a more conventional space? I thought this would be a good time to evaluate the good, the bad, and the ugly of this little interactive space experiment.
I’ll start off by saying that there’s a lot to like about the space and overall I’m really enjoying teaching in it. The students have really utilized the space well from the start. Sure, they sometimes still play with the microphones before class starts, but in the first class meeting students were already playing around with the laptop hookups and using the whiteboards. The tables are excellent for discussions. One thing I didn’t anticipate is how loud the room gets during group activities (there are 38 students in the class, so we fill most of the room), but I think the round tables help everyone hear and participate (and focus!).
The room layout is also a good visual cue for me. As I’ve mentioned before, one thing I still struggle with in my flipped classrooms is just shutting up already and letting the students get to work. Seeing the students all set up and ready to collaborate reminds me (most of the time, not always) to make my remarks brief so that the students can get to the task(s) at hand. The layout also makes it easy for me to visit each group during collaborative work and to interact with everyone in the group. It’s harder to hide/not participate at a small, round table! There’s definitely a community and a camaraderie in the classroom, and a pretty relaxed, comfortable atmosphere, and I think the space plays a large role in that climate.
Basically, the room makes collaborative work so easy and natural that it seems a shame to “waste” it on lecturing, so I’m more mindful of how I structure my class meetings. My pedagogy has really benefited from the space as a result.
There are some definite quirks of the room that take some getting used to. Luckily many of these quirks can be creatively managed.
First, with the teaching station in the middle of the room, I have my back to about a third of the class when I stand there. This forces me to walk around the room, which I tend to do anyway when I talk, so not a big deal. But it is problematic if I have to do a demo, or write notes (see next paragraph). I made a few jokes early in the term about my “rudeness”, so I don’t think the students mind too much, but it’s a bit off-putting to me.
Second, even though the room has tons of whiteboard space, the glare and sight lines mean that there’s no good spot for ME to write notes for the class. This is the biggest drawback, because I primarily teach using the board (I only use slides for complex diagrams and discussion questions.) So I don’t write on the board—I write notes on a tablet PC which is projected to the main screens in the room. It works, but it’s not the most natural thing in the world for me, which means I don’t write as much in terms of notes, summaries, etc. as I usually do on a typical board. Which means I think much more carefully about the points I do write/project for the class, so I guess that’s a net win.
Third, the room gets surprisingly loud. Now, I definitely don’t have a problem with vocal projection (I inherited my grandmother’s lack of brain/mouth filter and lack of an “indoor voice”), but even I have a hard time getting people to simmer down when I want to move on from an activity. There’s enough of a delay on the lights that flashing the lights doesn’t work well. I’m still working on a good mechanism to quiet down the room without destroying my voice in the process. (Suggestions welcome!)
There’s a lot of collaborative work we can do without computers in this course. However, at the end of the day this is a SOFTWARE design course, and every so often it makes sense to do collaborative work on computers (duh). There are no computers in the space other than the one at the teaching station, and students don’t reliably bring their laptops to class. This means that we end up sometimes meeting in the classroom and sometimes meeting in the computer lab—which is all the way across campus, in my building. (For instance, last week we met in the classroom on Monday and in the lab on Wednesday and Friday.) Now, there is a lab in the same building, but there was not enough time to get the software I needed installed in this lab before the start of classes, hence this imperfect solution. I do try to announce well in advance and multiple times when we have a classroom switch, but students are understandably annoyed when they accidentally go to the wrong room (it’s a 10 minute mistake—the time it takes to walk across campus). Also, I would much rather have the students working on computers in the classroom space, to facilitate cross-pair sharing and discussion (which is harder to pull off in the lab, set up like a conventional computer lab—long and narrow, computers in rows).
The room is quirky, and I wish it had dedicated computers, but it works, and works very well for this class. Here’s the most telling testimonial: I’m teaching this same class next spring, and I’ve already put in a request for a room switch so that I can teach the class in this room again. (Hopefully this will give me enough lead time to get the proper software in the computer lab in the same building.) I’m enjoying the way the space challenges my approach to class planning and to pedagogy, and I’m really enjoying the classroom climate fostered by the space. It will be interesting to get my students’ perspective on their mid-term evaluations—I am curious to see if their experience of the space is as positive as mine. Regardless, I’ve enjoyed the chance to try out a new-to-me space and break out of my normal teaching routine!
Long(ish)time readers of this blog know that I’ve been experimenting with a variation of the flipped classroom lately. I plunged in last spring with my Intro CS class, and it went so well that I decided to flip both of my classes this term. Overall, I am still pleased with the results, but in flipping two classes I’ve learned a bit more about the practical aspects of the flipped classroom (and time management, too).
For the purposes of context, the two courses are 200-level courses that are required for the CS major. One of these contains a broad mix of ability levels (everyone from seniors who have taken almost every course we offer to sophomores fresh out of Intro CS, and one intrepid first-year student), while the other is mainly students who have just taken Intro CS.
What’s gone well
I have yet to post a video: I’ve stuck with my original model of posting targeted readings for each class, along with a small assignment to test comprehension of the material. This strategy continues to work well. While I could probably buy myself some more class time if I posted mini lectures online, I’ve found that doing very targeted mini lectures in-class on the trickier concepts works well and usually leaves plenty of time for in-class activities. And the daily assignments, when I have time to review them, show me immediately what students are grasping and where they are struggling.
My teaching, I feel, is more creative as well. When your goal is to minimize lecture and maximize problem-solving, application-oriented activities, you have to think very carefully about what you’ll present and how. This has made me view the course material in new ways, and caused me to re-evaluate some of the topics I typically present.
I’ve also found that I stress less about getting “behind” in the content. I’m less concerned overall with presenting content and more focused on “are the students learning what I want them to learn from this unit”? Content can always be finessed to match the schedule. And again, this sharpens my focus on what’s really important in terms of learning objectives.
Finally, having the daily assignments worth a small number of points continues to be a fairly sufficient motivator for having the students do the work ahead of time. This is more true in one class than in the other, but I find that most of the students are doing the prep work most of the time.
The biggest challenge I’ve faced is finding a sustainable model for the daily assignments. Obviously, this was much easier to handle when I was teaching one course, but I completely underestimated how much time keeping up with the grading (even if it’s just a quick check) would take. I am way behind on the grading here!
Surprisingly, Moodle (our course management system) is much more of a hindrance than a help here. It takes FOREVER to grade even simple assignments: so many clicks, so much navigation! I’ve resorted to having students hand things in on paper at the start of class, which is easier for me to grade but means I can’t peek at their submissions before class to plan out our class time.
I’ve had more success with two types of assignments in particular: Moodle quizzes and discussion forums. Quizzes are auto-graded, which is wonderful, but the Moodle quiz interface also allows me to scan all the quiz attempts and see which problems people are missing and how many attempts they require before they can answer the questions correctly (and color-codes them too!). I find I am better prepared for class when their daily assignment is a quiz. With discussion forums, I can also scan the responses quickly and grade them fairly quickly too. In the future, I will definitely rely more heavily on these types of assignments.
Another challenge is that this type of course takes a lot more energy than a typical lecture course. I’ve found that when I’m tired or extremely busy (which is often the case this term), I fall back on lecturing because it’s “easy”. Yet I definitely feel like the more lecture-heavy classes are less effective overall—I joke that the more I talk, the less my students learn. The investment of energy up-front reaps way more rewards in the end, and if I invest the time up-front my students will, too.
What does the future hold?
Next term will pose a very interesting challenge: I’m teaching basically a new prep (a course I haven’t taught in 4 years that I am completely overhauling), an elective course on computer security. Essentially I’ll be inventing and flipping a course at the same time. Oh, and security is not my area of expertise, either. I’m glad I got the chance to play around more with flipping two very familiar classes and work out some of the logistical kinks before tackling a much more challenging-to-me course. Luckily, I have a lighter teaching load (1.5 instead of 2.5 courses) next term too, which should alleviate some of the time management issues as well. My experience in flipping 3 courses has strengthened my commitment to the concept, and I look forward to next term’s flipping adventure!
Tomorrow is the first day of school…for me, sort of (it’s our faculty retreat—classes start next Monday), but also, for the first time, for my daughter.
My daughter starts Kindergarten tomorrow. It’s a short day for her, just a quick orientation and a spin around the parking lot on the school bus and then she’ll go back to daycare for the rest of the day. The real stuff starts on Wednesday, when she gets on the bus and goes for the entire day, and then repeats that every weekday for the next 9 months.
She’s very excited. I’m very excited for her. I loved school as a kid (and still do, obviously, since I’ve chosen to work at one!). Loved the rhythm of the school day and the school year. Loved learning and mastering new material. Loved the challenges.
My daughter starts kindergarten knowing some simple math and knowing how to read a bit. (Fittingly, she read a bedtime story to her brother and me tonight.) She’s also starting with a ton of creativity and imagination. She has a love for science, computers, and rocks that is a joy to behold. I am excited to watch her add to her skill set this year. I am excited to watch her blossom. I hope school allows her creativity and imagination to continue to flourish. I worry that her love of science, math, and technology won’t be nurtured enough.
Having a school-aged kid (ack! I’m too young for this!) reminds me just how important my role as educator is. I hope that during this academic year, I remember that my students all come to me with their own skill sets, with creativity and imagination and their own passions. I hope I provide them with the right challenges to help them master the course material. I hope as well to allow their creativity and imagination to flourish in my classes as they become better, more effective problem solvers. Finally, I hope I can help them develop a new passion for CS (if they don’t have one already!), and help them mesh their other passions with this CS passion.
Happy first day of school, to those of you starting tomorrow! And secret message to my daughter: we are so very proud of you, and wish you all the best on your school adventure!
- Which is better: a book that provides excellent explanations/development of concepts but less-than-stellar examples, or a book with really compelling examples but scattered explanations/development of concepts?
- Why do so many books present stacks and queues before linked lists? We’ve always done the opposite. Huh.
- Is it time for lunch yet?
- Is it time for a snack yet?
- How much code can I expect students to read before their eyes glaze over and/or they start skimming? (even if it’s well-written code)
- Where is the line between “too few sorting algorithms” and “too many sorting algorithms”?
- Is this a damn-it’s-hot-and-I’m-dehydrated headache or a I’ve-read-too-many-textbooks-today headache?
- Will my students get confused if they have a generics-based textbook but we don’t code with generics in class?
- Will my eyes really pop out of their sockets if I read one more textbook?
- Why is this process so damn hard?
