E-learning

Courses that are taught through the Internet，or online courses，have become popular in many countries. 1. But most show a video of a teacher and students in a classroom. Students watch the video online and take part in online activities. Some courses are free and open to anyone, giving students anywhere the chance to study at any time.

2. Some schools in Singapore, for example, have tablets and touchscreens instead of books and blackboards in the classrooms. There are also social media platforms to help the students work together on projects, and online “worlds” where the students can interact with each other and the digital environment while completing different tasks.

3. The teachers are in their home countries and are connected to the Korean classrooms through the Internet. Instead of looking at a screen, the students interact with a robot in the classroom. The robot is controlled by the teacher and can move around the classroom and talk with students. It is unlikely that robot teachers will replace real teachers. 4.
