1st week teaching Macbeth!

It is never a dull week at EPH.  As a future teacher I am getting a lot of practice rearranging schedules and lesson plans due to un-forseen circumstances.  This past week alone we had a snow day, salt surveys and a little break out in the cold while the fire department investigated for a fire.  Thankfully, there was no fire!  Although, this seems chaotic, I think it is a valuable experience because we as teachers can't control the weather and all the circumstances at the school.  However, we can learn to "roll with the punches" and adapt to the changes as necessary.  After all, isn't being prepared, thinking on our feet and being inventive part of the job?
I did get to start teaching my unit on Macbeth this week.  Both days seemed to have gone well.  My only issue was during the discussion only a few students were talking about the topic.  I tried asking if anyone had a different opinion or comments on the existing ones, re-explaining questions, wait time, calling out students only to hear I agree with so and so with no explanation.  I can honestly say I was a little frustrated.   However, in the process I made a game time decision and switched up the activities. They did their work  while I walked around and talked to them, wondering how the discussion went so wrong.  I reflected on how I could have made them more comfortable to talk, or if they even understood the whole point.  I had a lot of questions raging in my mind.  After class, I read their responses to the question and they all had very different insightful opinions.  So I came to the conclusion that they understood the point because they all had an opinion but they were not comfortable speaking it out in the class.  I wondered if maybe it was the topic or if they were not comfortable with me.  My CT teacher and I went over the lesson plan later that day.  She thought it went well except for a few minor tweaks.  I asked her about the discussion and what she does when it falls apart.  She told me it happens.  Sometimes she has them go very well and other days she wonders what went wrong.  She did think I handled it well changing up the plan.   But I left thinking if this is a constant issue, why;  topics, attitudes, moods, time (period), atmosphere etc..  I still don't have an answer but I will forever be prepared with a back up plan if a discussion does not go well.
