Final answer:
Miss Caroline mistakenly believes that a.Atticus Finch taught Scout to read in 'To Kill a Mockingbird', but Scout learned mostly by observing Atticus read.
Step-by-step explanation:
In To Kill a Mockingbird, Miss Caroline thinks that Scout's father, a.Atticus Finch, taught her to read.
Scout has been reading with her father for as long as she can remember, which led to her advanced reading skills ahead of many of her peers.
Contrary to Miss Caroline's assumption, though, Scout picked up reading on her own by sitting with Atticus as he read the newspaper and other materials rather than him formally teaching her.
The teaching styles of Atticus, which are more nurturing, are contrasted with the rigid school education system personified by Miss Caroline's reaction to Scout's reading ability.
