video chatting in the Classroom

Online classes are becoming increasingly more popular and there thousands of students enrolling in them.  I am currently taking two online classes and one is a music class.  Though I had my felling and worries about this class in really has been pretty good.  It really got me thinking back to the post I did earlier about the crazy piano technology.  I really wonder if there can even be an online orchestra class where student log in via Skype or something.  This would allow people to receive musical input from the top notch teachers from around the world without having to pay for travel fees and such.  Of course there are some logistical things that would have to be sorted out such as GOOD wifi, but this is more of a perfect world idea.  However this would would also word for the classroom teacher who wants to do some type of collaborative teaching with teachers from other districts states and countries.  This will give students other perspectives on musical materials, different interpretations on musical ideals all the while saving the school money when it comes to bringing people in.  I guess you can say this post in more about video chatting in the classroom.  But my reasoning for putting so much emphasis on the video chat aspect is the online classes lack that personal connection students need with a teacher.  The video aspect still gives students a chance to have (even if just a tiny bit) some one on one time.  Music requires a lot of formative assessment and online classes lack that.  The video chat is a pretty cool and simple solution
