Well done Rick and thanks for sharing this situation with the group. This is my response, but it would be great to hear from others. Dr. Myron Tribus was correct, “Leadership belongs to those that seize the initiative.”
Great job taking initiative. You are beginning to understand your system.
First, you might consider involving the students in quantifying the Plus/Delta data. They don’t need to know the names of the teachers, just the feedback. You can swear them into secrecy. (They all know who the poor teachers are anyway.) I would probably take your Plus/Delta feedback and turn it into a Pareto Chart. I will upload an Excel Template for you to modify.
You need to think about the aim for this data. I am assuming it is to improve learning school wide. When you clearly state the aim, the teachers won’t think you are on a witch hunt for the bad ones. The more you use data to improve the system, the less teachers will be threatened by it. If you use it as a form of evaluation, they will rebel. The same is true for students.
If improving learning is the aim, then sorting the data by teacher would have only one purpose; to find a special cause. A special cause, statistically speaking, is outside three standard deviations. Or, the person or persons that are in the 2% range. Remember the phrase, ’98% of the result of any system comes from the system itself.’ Even if you identify a teacher outside the normal range, and if they are tenured, and given state laws on removing a teacher, you have little chance, if any, of getting rid of a teacher based on poor performance. So, the question comes back to where to spend the time. Do we spend time getting rid of the bad or spend time expanding the good?
A quick way to determine if you have a special cause teacher is to take all the data on the classes they are ‘learning the least in’. Each time a class is identified as ‘least learning’ put a tally mark by that class. Then count all the tally marks by teacher. When you put all the teachers into the Pareto Chart Template you will immediately see which teachers are causing 80% of the poor performance problem and if any are completely outside the rest(in a bad way). You can do the same with the ‘learning the most’ classes to see if you have a teacher or group of teachers who are consistently outperforming all the rest(again special causes). If you have special causes you will work with them separately, instead of inflicting training on the masses of people who do not need it. Of course to be more valid you would need the same number of random students from each teacher to give feedback.
After checking for special causes, spend the rest of the time expanding what is good.
Take the Plus feedback on classes where students are ‘learning the most’ and simply do the same process as above. Start a list of what is going well. Each time an observation is made place a tally mark. You may have to make a judgement on some comments, but you will eventually start to see common categories emerge. Now you will start to see what makes great learning at your school for your students. You can do the same for the Deltas. You will end up with two charts to share with teachers. Do more of these things ‘Pluses in order of most to least’ and do less of these things ‘Deltas in order’. You can now take the positive feedback and start to turn it into a more formal student survey. I can help you with that also when you get to that point.
Thanks again for sharing your opportunity. Let’s see if there is other advice.
Best regards,
David
