Videoconferencing is becoming a popular way to teach languages. A Daily Sun article describes how this technology works in a class for children:

"Holding a little stuffed snowman with a red nose and scarf, elementary Spanish teacher Xil Castreje sits behind a desk at the head of his classroom and waves goodbye to his students for the day.

Through the speakers on his desk comes the chorus of goodbyes from his class, while their waves can be seen both on the monitor on his desk and across the room, projected on the wall.

With class now over, Castreje works the laptop in front of him, shutting down the cameras on himself and the class located in another community."

Some subjects, such as language learning, require human interaction. Most students aren't able to learn another language by reading books or interacting on message boards. Fortunately, new technologies such as videoconferencing can help online learning work for almost all subjects.
