Hi Mary,
Would you allow your students to choose which discussion methods to use, or would you require that they all engage in every discussion?
I am currently teaching a totally synchronous class and I am finding that it has its challenges, as does an asynchronous classroom. Come to mention it, not everyone preferred learning the same way in my on site classes either.
I agree with you, multiple methods are the best way to go.
Thanks for your input!
Jane
