" Better Teachers Receive Worse Student Evaluations "
A One-standard-deviation increase in university teachers’ effectiveness in boosting student performance reduces the students’ evaluations of their professors’ teaching quality by about half of a standard deviation, on average .
Which means, if the Teacher is 10% more efficient, the students' rating is 5%  lower,  of that teacher ! Unfair ? Yes !
This is  enough to significantly reduce the teachers’ percentile ranking at the university .
Students, especially the least able, appear to respond negatively in their evaluations to the extra effort that good teachers require of them, a finding that casts doubt on universities’ reliance on student evaluations to inform faculty-promotion decisions !
The researchers also found that student evaluations improve when there is fog and as the weather gets warmer, and they deteriorate on rainy days.
