at the school vs in the school Is there any difference in meaning between "study/teach at this school" and "study/teach in this school"? Is one of them more usual?

I know the difference between "at school" and "in school" (without a demonstrative adjective) and that is outside the scope of the question.
Preposition confusion - Do you learn somthing 'at' school OR 'in' school? I know that we use the preposition at to describe a place. I learned French at school is one of the examples I can think of.   I came across two examples that use the preposition 'in' with 'schools' in the context of 'learning'.   Example #1 from the  website:      Eleven things that you will never learn in school.   Example #2 from      Do you think the skills you learn in school will help you get the job you want?   The use that I had in my mind is here on      Should Parents Control What Kids Learn at School?
