21. Christianity was part of daily school routine
In earlier times in our nation’s history, it was not unusual to have Christian lessons as part of daily instruction in schools in the United States, with students reading a passage from the Bible, usually at the start of school. That is no longer part of the day as the nation has become more diverse and includes children who practice other religions, such as Islam and Hindusim, or are not religious at all.
22. Teachers gave students responsibility to teach
There were fewer teachers in the past and sometimes a teacher would teach multiple grades. Teachers gave teaching responsibilities to older students to help younger or slower students learn.
