I would like to comment about making comments on people's posts. If you read about the community of inquiry, (https://coi.athabascau.ca/), you will discover that teaching presence is the supporting presence that makes the whole community actually function.
So, let me say that not only is it appropriate for you to ask each other questions, but it is imperative that you do. Teaching presence not only comes from the teacher (me), but comes in the form of directing questions and inquiry which is what gives the community direction and guidance for sharing our cognitive presence. Social presence is that which makes us comfortable doing so.
I have talked about this in previous posts with other cohorts of students. You can read one discussion here
In other words, to make the most of this discussion board and community, I charge you with asking pointed and direct questions of each other in the posts. This is to push each other forward in the quest for knowledge.
That is why we are here. That is why I love to teach. Students believe that they can ask the teacher questions. Well, students can also ask other students questions. In fact, students must ask other students questions. There is only one of me and many of you.
I look forward to a question-filled discussion over the next few weeks.
