Slow Learning: Mitten Ball Debates — Shannon Dea, Department of Philosophy

Mittens!

Sometimes, great teaching and learning solutions are right at our fingertips.

A couple of years ago, I was teaching a winter term night course. It was mid-way through the term and the students were clearly exhausted. My usually participatory class clammed up, and I had to do something.

I stopped “delivering lectures” per se years ago. As I’ve grown into my teaching, I’ve become less and less concerned about transmitting content, and much more interested in helping my students to engage with the material sufficiently that they’ll be motivated to seek out the content on their own. So, nowadays, I’m more of a facilitator or master of ceremonies than a lecturer. I don’t tell my students what the readings say; they tell me. And, as they do so, they tell me what’s plausible about the positions we’re considering and what requires a more critical response.

I’ve developed a bunch of different methods to encourage students to participate in class discussions, but that night nothing was working. My mind raced as I struggled to think of a way to kickstart the conversation. And, then it clicked.

I grabbed my wool mittens from my coat pockets, turned them inside-out into a soft ball and told my students, “Ok. Time for a mitten ball debate.”

I wrote a controversial statement related to that week’s material on the board. Then, I drew an imaginary line down the middle of the lecture hall and told the students that everyone left of the line was on the “Pro” side and everyone right of the line was on the “Con” side.  I gave them a few minutes to gather their thoughts and jot them down before elaborating the rules of the game:

  • The only person permitted to speak is the person holding the mitten ball.
  • Speakers must make new points, not repeat those points other speakers have already made.
  • No one may hold the mitten ball more than once.
  • After one has finished speaking, s/he must toss the mitten ball to someone on the other side of the lecture hall (and, hence, on the other side of the debate).
  • If you catch the mitten ball and have nothing to say, you may toss it to someone else on your side who has not yet participated.
  • Whichever team runs out of novel comments first loses. (Or, more constructively, whichever team doesn’t run out of points wins.)

I closed my eyes and tossed the ball toward the students.

And it worked. The discussion that followed was energetic and engaging. And, in the remaining weeks of the term, the students themselves several times requested mitten ball debates. There were several mentions of the mitten ball on student evaluations of the course, including such pseudo-koans as “Trust the mitten ball.”

So, what is it about mitten ball debates that students like? I’m still working it through, but here are a few of my ideas about this:

  • It’s fun to throw things. Moreover, having to follow a projectile with one’s eyes, to throw and to catch, pulls students out of the “alpha state” they so often slip into in three-hour classes. Just that little bit of physicality can make a huge cognitive difference.
  • Mitten ball debates involve everyone, not just the smartypants who sit in the front row with their hands up all the time. Students too easily fall into patterns about who the speakers are in the class and who the non-speakers are. Mitten ball debating is premised on breaking those patterns. And, students are often grateful when the usual suspects don’t get to weigh in three times on the same point. (The corresponding advantage for instructors is that, in a mitten ball debate, one need never say, “That’s another really great point, Smartypants, but let’s hear what someone else has to say…”)
  • Mitten ball debating takes the pressure off to make the best point. Since the game just requires teams to come up with as many points as possible, students are helping their team just as much with comparatively weak points as with strong ones. This means there’s less stigma associated with “saying something stupid.”

There are a few different ways you can run a mitten ball debate. You can, as I did, arbitrarily assign a position to each side of the class. Or, you can allow students to move to whichever side of the class corresponds to their own view. Alternatively, you might ask students to move to whichever side corresponds to the opposite of their own view. Adducing evidence for the opposite side is always a great exercise!

And, of course, there’s nothing saying you have to limit the teams to two. In a Classics class, for example, one could divide the class in three and have a mitten ball debate about the comparative merits of Julius Caesar, Pompey and Marcus Crassus.

When I’ve held mitten ball debates, inevitably, some students colour outside of the lines – either “crossing the floor” once they become persuaded of their opponents’ position, or remaining where they are but shouting suggestions to the opposite side when they notice an argument the other team has neglected.

Fine by me. After all, the point of a mitten ball debate isn’t to follow a bunch of arbitrary rules, but to warm students up to a topic that at first leaves them cold. I suppose it should come as no surprise that, even in the depths of the winter term, mittens help to provide a little warmth.

Using Videos as an instructional tool

Using Online Videos (made with WACOM board)

In my brief time as a sessional instructor for calculus in the last school term (May – August 2012), I had an opportunity to experiment with making videos. You can access my YouTube channel. I had been a fan of KhanAcademy and Salman Khan’s desire to supply free knowledge to the world long before his recent explosion of popularity. I had watched most of his calculus videos on YouTube just to get ideas on how to teach the topics effectively as a teaching assistant.

I had even begun advertising his videos to my class as an alternative to what I was teaching in class…(if they wanted to hear and watch someone else teach) until I ran into a five-week long chunk of material that the website didn’t cover, or at least to the level I was expecting my students to know it. I wanted my students to have that alternative. While learning in class can have significant benefits, there are many good reasons to consider videos:

1) Pause and Play, Learning at own pace: If a student misses something the first time, they can just watch it again. Some students require additional reinforcement, and instructional videos are a very user-friendly tool to provide it.

2) Shortened Attention Span: Videos shouldn’t be the same length as 50-minute lectures. Students don’t have to listen to concept after concept without having the chance to try the problems or have their understanding tested.

3) Additional Examples: In both math and engineering, a measure of success is being able to solve problems on certain concepts. Providing additional examples through video allows students to understand the thought process rather than simply seeing completed solutions.

Since I decided to start making videos in the middle of the term, I did not spend that much time getting acquainted with the process. I used a WACOM tablet (with stylus) that I borrowed from Mark Morton at the CTE (I have since bought my own Bamboo Capture Tablet from WACOM for about $80 on sale). In terms of software, I downloaded CamStudio (free) which is a screen capturing program, and used Microsoft Paint. In Paint, I zoomed out as far as I could, and made the drawing space as long as I could so that I could have a “scrollable” blackboard. Here is the end product (increase the quality for a sharper look):

I have to be honest. I know very little about video editing, so there was none (all videos were done in one take). If I significantly messed up, I would start over. So I intend on learning some video editing before creating the next batch of videos. I’ve also heard Camtasia works much better, but it costs around $300.

Some tips that I would have found useful before I had started:

1) Have a very clear idea and plan of what you will do and say. In my first attempt, I tried to have a general idea. I knew what problem I would solve and even have the solution in front of me. I didn’t have all of my explanations figured out though. While this spontaneity was not always a bad thing in tutorials, or in the classroom, students are likely to get bored or frustrated because they cannot interact with the video.

2) Talking and writing at the same time is more difficult than it seems. Again, this goes back to good planning. Making an effective lesson plan that outlines what will be said and written is very helpful.

3) Make sure the purpose of the video is outlined clearly at the beginning of the video. Videos that focus on examples may cater to a different crowd than videos that focus on additional theory.

4) Keep your videos short (not more than 10-15 minutes). If they need to be longer, offer them in shorter segments, such as theory, example, and example. Long videos make students lose focus.

In my future courses, it may be worthwhile to consider assigning some teaching assistants to make videos that supplement class material and guide students on problems. I had a chance to familiarize myself with clickers as well in the last term. My goal is to implement a teaching strategy similar to Eric Mazur (a Physics Professor from Harvard): where a video will be used prior to class to introduce students to a topic. Students will then come to class with their misconceptions and misunderstandings on concepts, and the in-class time will be spent on more interactive elements, such as clicker think-pair-share questions. Follow-up videos could then be implemented, but that’s a whole different topic for another time. Thanks for reading!
