More and more, students from different countries are studying together, discussing in different electronic (learrning) environments.
Some say all subjects in the curriculum are equally suited for international education. I doubt this. I feel we can and should profit from the opportunity of having different countries, cultures, expertises together, by selecting certain topics. My criteria are: (a) every participant knows something of the topic; (b) the participants have different takes on the issue.
According to 'persuasive arguments theory' (Burnstein & Vinokur 1973) these conditions are crucial, if a change of opinion is to occur. We can extend this reasoning, and surmise that learning will also occur.
As example of such a topic, I have used the cultural differences between students from different countries. Students found this interesting, because they could speak about this topic from their own experience, as well as learn from the (altogether different) experiences of others.
If you know of any other topics that seem extraordinary suited for an international learning experience, in your discipline, please let me know.
