Today more and more courses are given on the Web. The old personal interaction between teachers and students are disappearing. I feel that this is sad.
If one has a course with hundreds of students a Web course is appropriate. The managers at universities are also often happy with web courses because one teacher can manage a lot of students and hourly paid teachers are not needed. I personally have almost 1000 students that I manage in 6 months.
Many students like web courses because then they can work fulltime and still do their studies.
When a teacher has only web courses the teacher never has to visit the university.
In the university lecture rooms are disappearing and the corridors are empty.
