It is refuted that technology will replace the role of teachers in classrooms.
Rather than expressing your view on this passively, it is more effective if you express it directly.
However, I do not agree with the view that technology will replace the role of teachers in classrooms.A very important aspect of teaching is how the teacher can adapt the teaching style by live interaction according to the need of the students.
... the part I have highligted does not sound very clear.... better you re-phrase.
For instance, the teacher can motivate the students by giving advices or suggesting morals from good stories and discipline them according to the character of the student .
.... don't have too many ideas in one sentence. That disturbs your flow.
For instance, Maths is a subject which is difficult for some students find difficult .
If the student feels any difficulty in the subject, the teacher can explain the subject in detail.
... you can present this idea better;
An experienced teacher can think of some strategy to present this subject more convincingly to a student who struggles. The teacher's previous experience and understanding about his or her student play a vital role in formulating this strategy.
