Teachers are being evaluated with student tests that are deemed inadequate linear measures of achievement by real educators, but it is even worse than that. Teachers are being evaluated according to scores achieved by students in other classes and in other subject areas.
For instance, in our local school, music teachers’ evaluations include student performance grades in language arts. The same goes for social studies teachers, science and art teachers are often rated on math scores and gym teachers are usually rated by English Language Arts scores, but it varies.
Does that make sense to logical, normal people?
There are issues like poverty, intelligence, parental adequacy that are not included in student achievement tests, but that is supposedly addressed with a formula known as value added models. If you think that’s absurd, it is.
How would you like to be rated on the opinion of a colleague’s clients? That’s what is happening in education. It’s all part of the Common Core revolution and the allegedly higher standards we are striving for.
Even school test averages are factored into teacher evaluations at times.
When politicians get involved in education, they ruin it. When they’re not passing unfunded mandates, they’re passing illogical laws. They said they wanted to stop teachers from teaching to the test but all they care about are tests – bad tests.
In some cases, if teachers have high performing students and they don’t improve, say they stay the same – high performing – the teacher gets penalized. How is that possible? Remember those Value Added Models (VAMs) I mentioned? If the student exceeds the “predicted score”, the teacher gets credit, but if the student does not meet the predicted score, the teacher gets the negative mark on his/her evaluation.
Good teachers are getting hurt. That wasn’t the goal.
Check out how the value added model works according to the Gary Rubenstein website.
The is a scatter plot of scores for the same teacher, in the same year, teaching the same subject to kids in different grades. So, for example, a teacher might teach math to 6th graders and to 7th graders and get two different scores; how different are those scores? Here’s how different:
It has a correlation of 24%. This is a joke. Is this how we decide if a teacher gets tenure or humiliated in the newspapers?
This is completely ridiculous but the statisticians and corporatists like it.
If this is progress, give me the good old days.
