What is the easiest thing teachers could do more to improve education?

One thing I believe teachers could do to improve education is to be more present when teaching their classes. Nowadays, a large number of students complain that lecturers for example are just simply 'reading of the slides' from their presentations, which lacks engagement, when students can read them alone at home anyway. It's important for them to create a motivational teaching atmosphere which envigorates students instead of leaving them disinterested and bored.

In a world where technology is growing and to some extent making people more lonely, with reports of depression and isolation among youths on the rise - it is important therefore that teachers are aware of these issues, and make students increasingly aware of such issues by providing a stimulating teaching experience.
