One of the exercises that educators are periodically asked to perform is to look back at their schooling and identify their most effective teacher. I inevitably land on my high school pre-calculus teacher. She was a demure, petite woman who was, without question, my strictest and most effective teacher. I know that later, when I struggled through calculus in college, her teaching was one of the reasons I survived that class. Last week I read about a study where three economists tracked one million children from a large urban district from 4th grade to adulthood. The purpose of the study was to determine whether teachers evaluated on their impact on students’ test scores (value added approach, VA) had a lasting effect on what happened to the students in ensuing years. They found that students assigned to higher VA teachers are more successful in many dimensions including how much money they will earn. Who knew that you could trace your income level back to your 5th grade teacher?
As educators and elected officials struggle to figure out how to redo the way in which teacher compensation is calculated, it is clear that the metric of teacher effectiveness is going to be a significant part of the final solution to this challenge. Earlier I wrote about the need for a good evaluation system to help determine this. Perhaps students should play a bigger role in this conversation; no one has a better sense of how effective a teacher is. We need only think back to our school years to quickly remember teachers that stand out as being better than the rest of the pack. At age 15 I recognized that my high school math teacher was good. 38 years later I know that she was great.
Collaboration and Innovation
For the past few years we have been promoting collaboration among teachers as a way to improve student learning. There is ample research to support the benefit of teachers sharing ideas and also a general agreement that a collective effort is better than an individual one. It was with interest then, that I read an article this morning on the short comings of collaboration. The author’s main point is that innovation and creativity are more readily spawned by an individual working alone and that people, including teachers, should consider this.
In the case of education, there is so much that is common to the teaching experience that the working alone route does not make a lot of sense. I am convinced that we can learn from one another. What we need to avoid however, is spending time in collaboration for the sake of collaboration. It is imperative that the collaborative meetings are well facilitated and have just one or two agenda items to keep the conversation crisp. I understand that the big impact creations or innovations on our culture are often made by an individual working alone. Improving teaching does not require such a change. Rather, it needs regular review and refinements.
