I am not the native English reader.
I want to know what the "sentence 3" means, especially with the meaning of "run."
The reason why I quoted "sentence 1" and "sentence 2" is to help you understand the context of the sentence 3. By these parts are included in the article about teacher evaluation. Thank you for your help.
-
sentence 1:
Thus, a teacher who appears to be very ineffective in one year might have a dramatically different result the following year. -
sentence 2:
The same dramatic fluctuations were found for teachers ranked at the bottom in the first year of analysis.
– sentence 3:
This runs counter to most people’s notions that the true quality of a teacher is likely to change very little over time and raises questions about whether what is measured is largely a “teacher effect” or the effect of a wide variety of other factors.

In this context runs counter to would mean the same as contradicts or goes against.
Counter here means against as in counter clockwise, counter argument, counter intuitive. To run counter to is to move against or oppose.
