Hi Rochelle:
Media, of whatever source, are just tools. Like a carpenter, they havfe access to many tools, most with a specific purpose. So it is with teaching. Media choices are tools that can applied in a productive, meanigful manner, or turn out to be less effective, almost wasting the students time, if we've chosen the wrong tool.
There's the situation of the right tool at the wrong time, and vice versa.
