Her first-hand experience with real Chinese sources will surely have a strong impact on her future research. In our class, we were not really bothered by the inconvenience of not being able to sit in the same classroom. The cameras and screens work as vigilant monitors. They should always be alert and responsive, ready to speak out and answer questions. The only inconvenience I experienced was the difficulty of writing on the board.
Projector can be a solution.
But maybe the more sophisticated electronic writing board is better, since a lot of off-hand writing will be done in class. There was such a writing board in Denison's video room. But, unfortunately, some student from another class broke a cable at the beginning of the semester and we did not even have the chance to try it. If I had had that machine on my side in class, a lot more could have been done. The controlling station has the capability of doing so, but since I was not familiar with how it worked and was too overwhelmed with the daily duties, I did not try.
