What happened to change the children's perspective of their father? (Chapters 1-11)how did it change?

I think for the most part, Jem and Scout think very highly
of their father. However, in Chapter 10, they learn a few new things about Atticus which
cause them to give him greater respect. At the beginning of the chapter, they complain
about Atticus being "feeble: he was nearly fifty." Older than most of their classmates'
parents, Atticus had a boring job, didn't play sports and wore glasses. However, when
Sheriff Tate suddenly handed over his rifle to cut down the rabid dog, the children's
whole outlook changed. "One-Shot" Finch had been the greatest marksman in the county,
yet he had never told them about it. They learned not only about his sure-shot status
but also about the definition of humility. Additionally, they learned that he
deliberately lost when playing checkers with them. They came to understand that he had
some very special traits after all.
