The education process is moving beyond the traditional classroom/lecture setting. More and more teachers are seeking tools and techniques to engage their classes and enrich their lessons. Video calling is one of these tools, as it removes barriers to communication and lets students move beyond the boundaries of their classrooms.

With Skype video calling, teachers can provide their students with first-hand knowledge from experts around the world and with other classes who are studying the same subject halfway across the world.
