Social/Ethical Issues

Authenticity
Teleconferencing would actually decrease the issue with authenticity. Since both sides would have real-time feeds of each other, neither side would have to question if the person they are communicating with is who they think it is.

Equality of Access
Teleconferencing is not available to everybody, since not every school may have the funds to purchase or to set up teleconferences, so there is not really equality of access.

Globalization and Cultural Diversity
As long as the two locations have the necessary pieces of hardware and software, they will be able to hold teleconferences with each other and share ideas at real-time. Schools from all around the globe can hold teleconferences with each other, which can lead to the students from different countries learning about the cultures and customs of another country, helping to increase cultural diversity.
