When our daughter was in elementary school, it seemed like each grade had that teacher.. the one that the parents did not want their children in that class.. The kids did great and loved the teacher, but it was the parents that had the problem with them.
The one teacher that the parents cared the least for on campus, our daughter had her for math in fourth grade.
I was a PTA officer almost every year our daughter was at the school. I also found this teacher aloof.
When our daughter was finished with 5th grade and it was tie for middle school, i asked our daughter who was your favorite teacher at school.
She said "I had a lot of favorites." She then listed them.. "But the teacher i learned the most from was, Mrs. F." Yep, the teacher that so many parents demanded they did not want their child in her class.
I actually admitted to our daughter that this teacher was really disliked by parents. She was shocked..
When i told her the reasons.." The teacher, never smiled, She seemed brusk, defensive, stand offish.." Our daughter said "No Way!" "She is so funny. She is so patient, and she can teach math in so many different ways so we all could understand!", She made sure the kids behaved, while it was time to work, but when we all finished our work, we had the best time in her class."
And so I learned that teachers, may not be great with parents. Maybe shy, maybe intimidated.. Maybe feel judged.. But that does not make them bad teachers.. Could be that is why they are successful in the classrooms, but not popular with parents.
