One of the benefits of online learning is convenience. Instead of having to study at one location, learning and teaching can be done at home. Teachers and students can study on a tablet or laptop so learning can take place almost anywhere without having to worry that the classroom is too far from home. Online learning also saves time for teachers, students and parents. No more travel, shuttle or worry about the distance to class, and that time can be spent on other activities. While in the classroom, some students could not clearly see the writing on the blackboard when the teacher was giving the lecture. This also affects the student's ability to concentrate and absorb. The difference of online learning is that they allow participants to share their screens during the lecture. This is more convenient for lectures because everyone can clearly see the content, increase the ability to focus and absorb the students.
