This question is an attempt by the interviewer to let you talk for a while. Typically, the principal's goal is for you to talk about 80% of the time. She wants to assess your ability to "think on your feet." She's looking at how articulate and coherent you are. How you express yourself. Your vocabulary.

It would probably not be wise to attempt to support either extreme on the continuum. You might start your answer with the dangers inherent in taking either extreme position. Constant sameness may promote boredom and a dull learning environment. Constant change may prove too chaotic for a viable learning experience for your students.

After expounding on these thoughts, you might speak to the value of some sameness. Routines can be helpful to students, especially those with learning difficulties. Describe some of the routines you would be comfortable instituting in your new teaching position.

Next, talk about the value of some change. Keeping students interested and on-task is a good goal for every teacher. Talk about how you might use the element of surprise to keep your students eager and enthused.

If you don't have examples of situations from your student teacher (or previous teaching job), recall lessons from some of your favorite (or least favorite) teachers.
