Why don?t teachers motivate students by telling the stories of scientists to make them think in the way scientists thought before they proposed their theory that we are studying today?

Definitely teachers can motivate their students by telling them about famous people such as scientists. When I was studying at St. Joseph?s College in Trichy, once a week the senior teacher used to give us a class of about one hour about one famous personality. This used to be called the moral science class. Schools can take this up today.
