The role of schooling has changed over time. From the first schools, which were set up to train children in basic skills, to modern-day schools that focus on providing a wide range of subjects, the role of schools has become more diverse. In the past, when most people worked in agriculture or other trades and manufacturing jobs, there was a need for students to learn practical skills such as reading, writing, and mathematics. Today's jobs require much more than this; they require people who can think creatively, solve problems and communicate well with others. As a result, there is an increased focus on teaching children about technology and preparing them for careers in science and engineering fields. In addition to these changes in curriculum requirements, there has been a shift in the way we educate our children about social issues. Schools used to emphasize obedience and respect for authority figures such as teachers and principals. Nowadays it is important for them to teach students how to think critically about social issues such as gender equality or environmental sustainability. As part of their curriculum, they may include lessons on these topics or invite guest speakers to share their knowledge with their students.
