I think that Online education has two advantages.
First, Online education can study at home.
For example, Student who can't learn at school by sick,
he can learn on online as who goes to school.
Second, Online education can use chatroom.
In this place students can question to their teacher at home.
Also, Students can teaching each other.
But Online education has two disadvantages,
First, A digital divide problem.
We can't online education without digital devices.
Students who can't buy a computer because they don't have
money can't learn online.
Second, Online education will be sometimes but connection.
