Strategic Interaction: The Impact of Mobile Technology (iPads) on Learning

October 24th, 2011 Comments off

Here is the video link of Dr. Emily Ritter’s presentation, in which she describe how she, Dr. Park, and Dr. Vonnahme looked at the impact of iPads on a student-centered activity designed to teach strategic thinking. The blog posts describing this activity can be found at these links: Part 1 and Part 2.

[see part 1 of this post]. . . We also used the iPads in a variety of ways for our respective research. The iPad is small and light, making it very easy to travel with. The 3G service is excellent and cheaper than paying for service from conference hotels. Though we have not used the iPad for presenting, this is definitely possible and others at our conferences have done so with great success.

Reading articles and drafts is very easy and comfortable on the iPad: Dr. Vonnhame likes iAnnotate for reading and marking pdfs, and Dr. Ritter uses PDFExpert, which syncs the marked pdfs with the eternally useful cloud storage space, Dropbox. The ability to both read and mark-up documents is particularly useful when acting as a discussant of a panel or discussing a project with a colleague at a conference.   However, Dr. Ritter, for instance, still travels with a laptop in order to edit her presentation slides, which you cannot do if you do not opt to use Keynote.

Dr. Park used the iPad for collaborative research with people from other parts of the country.  For instance, he communicated with co-authors using the Skype app and shared files via Dropbox app – it has been much easier for him to do these activities with the iPad as compared to with the laptop computer simply because the iPad is light and convenient.

Dr. Ritter also used the iPad while doing interviews in Europe this summer. She only used it for notetaking (using Evernote) and not recording (though Evernote does record audio connected with your notes), but the iPad was much less obtrusive than using a laptop to take notes, making it easier to speak freely with the subject.

For a pen and paper replacement app, Dr. Vonnahme tried two: WritePad and Penultimate.  WritePad converts hand-written text to typeface.  Dr. Vonnahme’s handwriting is somewhat cipherous and the conversion was a complete mess (over 80% of the words were converted incorrectly, often to non-word characters).  Penultimate is just a pen and paper replacement app with no conversion.  Writing was smooth and responsive, and notes could be easily organized into different “notebooks”.

Overall, the three of us found very different uses for the iPad and felt differently about them. Dr. Vonnahme quite liked the iPad, especially teaching with it, due to its flexibility. Dr. Ritter, in contrast, enjoyed using the iPad for its size and flexibility, but found that most of the things she did with it could be done (sometimes more efficiently) with a traditional computer, and she was rarely able to eschew the use of a computer in favor of the iPad. Dr. Park also liked the iPad in general for its flexibility and versatility and found that it could develop into a very teaching-friendly device in the near future (not entirely at the current moment, though).

–Hong Min Park is an assistant professor of Political Science.  He was born and raised in South Korea, and received B.A. from Seoul National University and Ph.D. from Washington University in St. Louis.  His research and teaching interests include U.S. Congress, political parties, and American political institutions in general.

–Emily Hencken Ritter is an assistant professor of Political Science with a PhD from Emory University in Atlanta, GA. Her research and teaching interests center on the way a variety of institutions affect human rights violations and domestic conflict, including work on treaties, international and domestic courts, and executive political survival.

–Greg Vonnahme is assistant professor of Political Science.  His Ph.D. is from Rice University in Houston, TX and his research and teaching interests are American voting behavior, elections, election reforms, campaign finance, and state politics.

Drs. Hong Min Park, Emily Hencken Ritter, and Greg Vonnahme–iPads in Political Science, pt. 1

Hong Min Park, Greg Vonnahme, and Emily Hencken Ritter, of the Department of Political Science, submitted a collaborative grant for the College of Arts and Sciences iPad Initiative. We each used the iPad in different ways in our own classrooms, in addition to collaborating to create and execute an activity across two sets of students. We also used the iPad in our research.

Dr. Vonnahme used the Airsketch app (with the Pogo stylus) to present slides during lecture, giving him more flexibility in the classroom during lecture, particularly to write on the slides while speaking, moving, and interacting with the students. The freedom allowed him to combine prepared material with content generated during the class period. It was particularly useful because the projector screen limits the amount of whiteboard space left to use during class. Here are some examples of slides, edited during lecture with the app.

Airsketch slide 2

Note the app allows the professor to use different colors for a variety of emphasis, etc. The app also allows the professor to save the amended slides so that students can refer to them later. Though the app occasionally froze such that a backup plan to continue lecture was useful (e.g., PDF Presenter with VGA connector), an updated version released in early April 2011 seemed to solve the problem.  Overall Dr. Vonnhame prefers the reliability of the iPad and stylus and the flexibility of the iPad to the system of stylus and lecture capture available through the classroom PC/podium.

In contrast, neither Dr. Ritter nor Dr. Park used the iPad to present lecture slides.  Dr. Ritter uses clickers (Turning Technologies) in the classroom and these are not (yet) compatible with iPad use.  Dr. Park tried several apps to “replace” clickers (eClicker, iResponse, ResponseWare, and etc.), but experienced no complete success – this could be useful only when all students have internet-enabled devices.

Dr Ritter used iPads in a group activity, asking students to answer a question as a group and report their collective decision in an audio format, using QuickVoice, but giving them the option of written reporting as well. The students were enthusiastic to report their assignment in audio format, and their answers were more complete and suggested more consensus than those answers from groups with written reports. Informally, the answers were more consistent with course material in the audio answers than the written answers – this seemed to be due to the increased consensus required to develop an audio response.

All three professors worked together to develop an interactive activity and “experiment” with the iPads. Principal-Agent Theory is an economic theory of strategic interaction that is widely applicable in the study of politics, so Dr. Ritter gave the same lecture on PA interactions to both her class and Dr. Park’s. She then assigned an in-class activity to both classes – her class completed the activity on paper, with a single prompt, and his class completed the activity using the iPads.

Using the Safari browser, Dr. Vonnhame designed an interface such that one group could act as the principal, making a decision that affected the agent’s options, and another group could act as the agent.

The groups were assigned points based on the decisions they made, in accordance with the standard incentives in Principal-Agent games. The groups’ choices were connected, such that each affected the other’s point allocation. They were given chances to interact with one another and play again.

Principal-Agent iPad activity

After both activities (the paper-based one in Ritter’s class and the interactive, technological one in Park’s class), we administered a direct assessment (not for credit) to determine how well the class learned the concepts after each type of activity. We found no significant difference in learning across the two activities, though students were considerably more enthusiastic about the activity with the iPads.  Go to part 2 of this post.
