Making Changes in Education

I found our discussion on the theories of motivation very interesting. In doing research for my paper on student-led conferences I googled 'motivating teachers' and a very good article came up discussing the exact theories we discussed in class. (expectancy, equity and job enrichment) My experience has been that teachers are very difficult to motivate to change. We have several changes in our district going on right now and it is intriguing how the teachers are handling the changes. I have worked closely with the administration the last several years on changes we have initiated and have seen different administrators handle the situation differently. I have not quite developed my own personal philosophy yet, but am very interested in this subject area. My first instinct is to be authoritarian and say here is the change that needs to be made and it is in the best interest of the students. However, I know that you must get teacher buy in to make successful changes. Where I struggle is how much "say" do you let the teachers have. I have been trying to develop a 6 - 8 advisory program and the 6th grade teachers have been very open to the idea but the 7 - 8 teachers have not. At what point do we say, the students need to continue advisory at the 7 - 8 levels and not let it be a 'choice'?
