With all the safety concerns now of days, taking a class on a field trip is a lot more difficult than it ever has been before. The use of Webcast in the classroom is like being able to take students outside of the classroom without actually leaving the classroom. This new technology for classroom is very for learning new things from people that aren’t at your direct face to face advantage. I have learned so much for the two classes we had webcasting with education people that I never would have learned otherwise. Also to Webcast someone cost no money to the students what so ever like a field trip would so everyone gets the equality chance to learn from it. I can only imagine how excited an elementary school class would be seeing and talking to someone new and interesting on a board!
