Hello! Could I have my writing corrected?

Task: The Internet will never replace traditional course books in schools. How far do you agree with this prediction?

It is predicted by many that there will always be a place for conventional course books in schools however beneficial the Internet is. In my opinion, I completely agree with this idea for two reasons.

On the one hand, course books are a reliable source which has been developed by pedagogical experts whose knowledge and methodology are tremendous. This means that they are proven to improve students' academic achievement, enhancing their potential for progression to further or higher education. Students of all school ages can count on this kind of material to assimilate knowledge and study skills.

On the other hand, there are a lot of sources on the Internet which need critical thinking to discriminate between them and sift information to marshal their facts. This is a mature skill which school pupils are not assumed to be ready for this.

Therefore, I believe that course books always remain an integral part of school curriculum, while the Internet can play a role as supplement.
