From where does Scout receive her most valuable educational experiences?

In To Kill a Mockingbird, Scout receives most of her most important education from home. When Jem and Scout first meet Dill, Jem says that Scout has "been readin‘ ever since she was born." On Scout's first day of school, her teacher finds it disappointing that Scout can read. Miss Caroline tells Scout that her father should stop teaching her. Scout says she "never deliberately learned to read," it just happened. Scout is then reprimanded for writing, which her teacher says shouldn't happen until third grade. While Atticus is to blame for Scout's "crime" of reading, she says that Calpurnia is the one responsible for teaching her to write.
As the child of a lawyer, Scout absorbs knowledge from Atticus through conversation and the content of the materials Atticus reads to her. As an example, during Tom's trial, Scout recalls that asking a witness a question "you don’t already know the answer to, was a tenet I absorbed with my baby-food." However, Atticus also teaches Scout more than reading. He teaches her morals by example. Scout learns many life lessons as her father represents Tom Robinson in court.
