A reading seminar where every student reads, writes and contributes to the discussion in class

16 Jan

I remember reading seminars as follows: one student spends the entire week preparing for a powerpoint presentation, which often turns out to be stressful for the student and somewhat boring and uninformative for the audience. The other students only glanced over the paper and so any discussion quickly falls flat. I therefore decided to have multiple short presentations without powerpoint (less preparation, more fun to listen to, plus repetition is good for learning a skill). I also decided to use short writing assignments as homework to make sure that all students were prepared to contribute to the discussion in class. At the same time, I wanted to keep things manageable for everyone.

1. Learning to present: every student does multiple short presentations without powerpoint.

No powerpoint: I didn’t want students to spend too much time preparing a presentation. I believe that often, when students spend a lot of time preparing presentations, they focus too much on making powerpoint slides and not enough on informing the audience and telling a story.

Short presentations: Doing an engaging 45 minute presentation is extremely difficult, and a skill that most postdoc don’t have, so why do we use 45 minute presentations in our graduate seminars? I decided in stead to let each student do three 10 minute presentations.

Feedback: After each presentation the presenters got feedback (from the other students and myself), so that they could improve their presentation skills during the semester.

Easy listening: An added benefit of 10 minute presentations is that it is much easier for the audience. Each week started with three student presentations, one on the background and main question of the paper, one on the data and the results of the paper, and one on the conclusion and implications of the paper.

2. Practice writing: every student does a different writing assignment every week.

Graded homework each week: A paper discussion can only work if people have read the paper. If students don’t read, they may spend most of their energy to try to hide that they didn’t read (I know I was in that situation!). So even though I understand that life and research get in the way of reading, I really wanted to make sure that the students were prepared for the seminar. To do that, I made every student do a written assignment every week that would count towards their grade (unless they were presenting that week).

A different assignment for each student: I had a long list of assignments so that each week, many different assignments were done AND so that over the course of the semester each student did many different assignments. This guaranteed that the students read the paper, but each with a different question in mind.

There were several types of written assignments. Descriptive: 1. Describe the background and main question of the paper, 2. describe the data and the results, 3. describe the conclusions, 4. describe which virus the paper is about. Critical: 5. What is your opinion of the paper? 6. What do you think the authors should have done differently? 7. Play the devil’s advocate: why should the paper not have been published? Summaries: 8. Summarize the paper in your own words, as if writing to a friend, 9. summarize the paper using only the most common 1000 words of the English language, 10. summarize the paper in a graphical abstract, 11. summarize the paper in a tweet. Meta: 12. Who are the authors of the paper? 13. How often is the paper cited, do you think it is influential?

Short! Each written assignment could not be more than 150 words, to keep the workload manageable for me and for the students.

Surprisingly hard: Some of the assignments were harder than the others. Summarizing the paper using only the 1000 most common words from the English language turned out to be very hard, but some of the students did a great job (see here and here). The graphical abstract was also hard for some students, but others liked it just because it was so different from their usual work (see here and here). The ”devil’s advocate” writing assignment was always very interesting to read.

Easy: Grading the written assignments was quite easy. I simply gave a plus or minus for 5 categories (answered the question, scientific accuracy, clarity, grammar and word count).

Revisions allowed: After a request from a student, I decided that the students could redo any assignment where they had gotten less than 100% because I believe that feedback is most useful when it can be applied to a revision.

3. Promoting equity: thanks to the written assignments, every student could contribute to every class.

Everyone contributes: One of the nice things about the homework schedule with different assignments for everyone is that in class, I could ask each student about their homework. This way, each student contributed to the class, promoting equity, and the brief discussions of the homework assignments always let to questions from other students. Even if I didn’t ask, some students would volunteer to share information they found while they researched for their homework. For example, I remember someone remarking at the end of a presentation: “In your presentation, you said this result may be very important, but I found that the paper hardly has any citations even though it was published ten years ago, so I think it may not have been picked up by anyone.”

Sharing homework: I also encouraged the students to share their written assignments on the online forum we had for the class, so that the other students (and not just me) could read them. Sometimes they led to interesting forum threads. I also published some of the written assignments on my blog, after asking the students for permission. This way even more people could enjoy them.

No powerpoint allowed

One of the students in my class (Arturo Altamirano) as he is giving a talk about Influenza virus. The drawings on the whiteboard were a very helpful for understanding his presentation.

One of the things I did in my seminar this semester was to prohibit the use of Powerpoint or any other presentation software. For their talks, the students had to use the whiteboard or handouts or anything that didn’t require a projector. Most of them used the whiteboard. Initially some of them didn’t like it much. But every student had to give three short presentations during the semester and so they had a chance to improve their whiteboard skills during the semester.

Focus on the story

I asked them not to use Powerpoint because I wanted to make sure that they did not spend a lot of time preparing beautiful slides. Instead, I wanted them to you to focus on the story of their presentation and the connection with their audience. I’m happy that I made this decision because the presentations that students did were really nice and I think they wouldn’t have been as good if I had allowed Powerpoint. All of the students improved their presentation skills during the semester and as the semester progressed, it got more more fun to listen to their talks.

Whiteboard exercises

One thing I will do differently next time is that I will start the semester with some exercises to become familiar with using the whiteboard. I am thinking about asking each student in the first class to introduce themselves using the whiteboard. For example, they could draw (very roughly) the geographic location of the cities or neighborhoods in which they have lived. The exercise would be to combine drawing on the whiteboard and talking to an audience. And hopefully, such an exercise would take away some of the fear they may have about talking without slides.

How I made a whiteboard movie

8 Feb

Several people have asked me how I made the whiteboard movies about my work (see here and here). So here is a brief explanation.

1. First, I make drawings on paper and write a text that will go with the drawings.

2. Next I make the drawings on a small whiteboard and record it with my iPhone.

Here is a picture of my set-up for making the whiteboard movie. The pink thing is my iPhone 4, which takes the movie. I need several light sources to reduce the shadow from my hand (but they shouldn’t leave a reflection on the whiteboard).

The iPhone is mounted on a tripod with a special iPhone part. Maybe a different camera would be even more convenient, because with the iPhone I cannot zoom, and thus the height of the camera isn’t flexible.

3. After I shoot the movie I import it to iMovie, where I can cut it, speed it up and add a voice-over. I use a simple plug-in microphone for the voice-over. 

4. When everything is done, I ask someone else to look at it and I realize that the story has to be told in a slightly different way, so I start again at step 1!

Making a whiteboard movie is a lot of work, but it is lots of fun too.

If you make one about evolution, consider sending it to the NESCent film festival. You can win a $1000 travel award. Last year my movie about slavemaking ants was the winner:

New video on slavemaking ants

27 Mar

As I announced a few weeks ago, I have been working on a new video on my work on slavemaking ants. It is now ready and online!

In this video, we talk about our research on slavemaking ants and their hosts (slaves). The slavemakers are of one species (P. americanus) and the hosts of another species (T. longispinosus). Host ants can be captured by the slavemaker ants, and these captured ants (slaves) normally work for the slavemaker queen. But recently, it was found that they sometimes kill slavemakers (Achenbach and Foitzik 2009 and Pamminger et al. 2013). It is unclear why the slaves do this, because they probably cannot reproduce.

The video is based on the paper: “Oh sister, where art thou? Indirect fitness benefit could maintain a host defense trait” by Tobias Pamminger, Susanne Foitzik, Dirk Metzler and myself, which can be found here: http://arxiv.org/abs/1212.0790. Earlier, I wrote a blog-post about this paper for Haldane’s Sieve.

Susanne Foitzik, who is a professor in Mainz (and previously in Munich) and her students and colleagues have been working on this slavemaker-host system for many years. Another video of our work is here: Raiders from the sky.

The music for the video was taken from the Free Music Archive.
