On p. 159 the authors share an example of a conspiracy of silence held among hospital workers who were violating protocols, rules, laws etc.
As I reflected, I transfered this concept into our world. Most of my experience in education has been a culture of silence and isolation, where teachers shut the door and do whatever they want to do, with little accountability for what takes place int he classroom. As several of you have pointed out through Marzano and others, the quality of the teacher and the quality of the instruction can help overcome many obstacles for struggling learners.
My question lies in how we hold teachers accountable once the door is shut. Is the commonly used dog and pony show of comprehensive evaluation truly effective? I think back to my time in the classroom where I had friends who were (and probably still are) terribly ineffective teachers, but could spit-shine a 2 or 3-day lesson for an observation and come out looking like gold. I have found that the 2-minute walk-through gives me a much clearer picture of what's going on in the classroom. Obviously we can't be everywhere all at once, and evaluations (both walk-through and comprehensive) only provide a snapshot about what's going on, but is there a better way to hold teachers accountable that we're not thinking of?
As an teacher, I enjoyed the concept of the PLC. It gave us a chance to sit down and talk shop in a small, open environment. The interesting thing we faced in our PLC's was that over time, they morphed into an arena to confront and question colleagues who are doing stupid things in the classroom. My initial reaction was that although this was always done respectfully and with tact, that the discussions were counter-productive. Since that time (and as I read this chapter), part of me thinks those discussions were very productive. I witnessed firsthand many times that being "called out" (respectfully) on a waste of classroom time, a foolish assessment practice, or anything else in front of the group of colleagues was much more of deterrent than a "low score" on a comprehensive evaluation. As the author stated, "no resource is more powerful and accessible than the persuasion of the people who make up our social networks."
