Do teachers need to create Web based activities for EFL students in the kingdom of Saudi Arabia? Why and why not?

Nowadays, Creating Web based activities are very important and helpful for students to learn , not only in Saudi Arabia but in all the world. So, absolutely teachers need to create Web based activities for their students.  And I think its very comfortable when the teachers make their own website to learn their students. 

Web based activities have a positive results for students in subject.  It make a subject more easier and make students interesting to do their subject. 
Learners need a new way to learn whatever they want. And teaching with technology it comes with a positive results.  I think learning through a technology is the best way to learn.
