Responding When Kids Don't Learn

Dufour, et. al, present the case in Whatever It Takes that schools react differently when students don't learn.  I think that teachers respond differently as well.  After having read the descriptions of the reactions, I decided that I belong to the "Pontius Pilate" school.  This is the one that says that the teacher teaches and it is the students' jobs to learn and they are responsible for their own decisions.  I am not sure why this name is given to this school but I think that it may have something to do with the fact that this Roman despot was the one who washed his hands of the responsibility of Jesus' death.  I don't want this to be me, so I am interested in reading about a better way.  The "Henry Higgins" school is more like how my school is currently trying to achieve better results, i.e. new strategies are employed and teachers are working harder to get every student to succeed.   
Whatever your philosophy of the best approach is, Dufour makes a valid case that in PLC, the teacher knows what he/she wants the students to learn before beginning the unit.  Again, this goes back to having a target to hit.  I have used small-group tutoring and one-on-one help for my students and have found that it is successful, but I also think that the students have to buy into wanting to succeed.  And I agree with the author that students who have difficulty learning should receive additional support, regardless of who their teacher is.  This is not happening at my particular school. A handful of teachers offer extra help while others head out the door at the end of the contract day.  I don't think that we can be a PLC school until all teachers share the same vision that part of our job is to help the students to succeed, "whatever it takes".
