Is podcasting the way to go

When looking at my 2nd assignment, the first thing that I looked at was using podcasting and did it fit into the school's VLE. I put this question to some senior teachers, i.e., teachers of grades 5 and 6 and they quickly told me, no. They argued that podcasting was a far to "wide" a tool for the children to use. They all thaught that it allowed the children to wonder far and wide and that the question of security came into play. They were not prepared to monitor their activities, as we have over 100 senior students. I selected Thread Voice as the principle means of view my 2nd assignment because of their concerns. Therefore, podcasting cannot be part of my PLE. My PLE, is dictated very much by the environment I work in. I think that people are restricted by the environment they work in.
