Teacher, Teacher - The Smartphone Fell Off the Wall

Yes, it is true.
When I videotaped my class over a week ago the smartphone was taped to the wall but it fell down.
I quickly picked it up and put it back into place with the sides and bottom both taped.
No problems after that.

I am very lucky as I have taught at a university and now a teacher training center.
As a result both me and my students speak in English during class time. For me I get to use my L1 and the students their L2. In my current job the students speak in English, their L2, all day and night at the training center from Monday to Friday.

As I analyzed my transcript (at least 15 minutes of it) I was suprised at how often I use SO to start sentences. I do have a tendency to use OK too much but I was surprised at the numerous SOs used.
Another negagtive I noticed that I did TURN COMPLETION too often when they were working in pairs. I either quickly corrected what they wrote or said, or I did not allow them time to modify their work with prompts from me. For example: "you need the possessive here. Good." Or "Do not worry, you can say commercial." I am now consciously in class during pair/group work trying to allow them time to fix errors I see or hear. I suspect my interruptions and my direct error correction were obstructive towards having the students correct themselves. My activities that day tended to have many referential questions (no known answers). The students had to answer questions their partners made using the "What would you do if...?" structure. With the pair activity it was "student-initiated intercation" but only with their peers. I did not give them the opportunity to evaluate my responses.
My turn taking was clearly individual nomination as I picked Lilly to model the activity with me. I am a little reluctant to invitations to reply as I am worried that dominant students will always answer. I wnat everyone to participate and contribute.
While the students were talking in their pairs I engaged in lots of corrective feedback on both content and meaning. Example: "this one can have two different prepositions - in and at. Both are correct. But I would say that native speakers use "at". What do you do at home on the weekend is better."
I think I would have done less direct corrective feedback if I had chained questions for them and given some wait-time instead of rushing to make changes.

One technical thing I need to work is the mic.
When speaking to the class all my teacher talk was audible and the student responses were as well.
But when they were in pairs I was not able to pick-up what I said at times and I rarely could hear their words on the recording. Maybe practice will rectify that problem.

Next time the smartphone will not fall off the wall.
