Do you ever think about what schools will be like in the future? Many people think that students will study most regular classes such as maths, science and history online.

Students will probably learn these subjects anywhere using a computer. What will happen if students have problems with a subject? They might connect with a teacher through live video conferencing. Expert teachers from learning centres will give students help wherever they live.

Students will still take classes in a school, too. Schools will become places for learning social skills. Teachers will guide students in learning how to work together in getting along with each other. They will help students with group projects both in and out of the classroom.

Volunteer work and working at local businesses will teach students important life skills about the world they live in. This will help students become an important part of their communities.
