I'm just getting started; so I set up a blog for my two Intro to Philosophy courses and I will at first have them connect and comment on each other. Ximena suggested that I could have students access the blog and comment instead of giving each student permission to be a member. I have done that last semester and it worked well, so I will probably do it like that for now and change it later.
Students will have to write a persuasive argument (following given criteria) on a topic of their choice, and then they evaluate each other.
This past week I have also been thinking about teaching online classes; next semester I will probably teach my Phil of Law class as an online class. It seems that most people who have taught online used Blackboard as platform for this, but I am not very fond of the Blackboard discussion feature, so I would prefer a blog or perhaps a facebook group. Has anyone of you taught an online course used one or more of these?
