While you do present some interesting topics in defense of your thesis, I believe that the prompt is asking for something deeper than a comment about the technical aspect of teaching such as methodologies or spoiled kids and demanding parents. I would suggest that you try discussing this essay from another point of view, the view that because of technology and the advent of the internet, teachers need to stay one step ahead of their students. So they need to be able to anticipate more complex and confusing questions from students.
I happened to write an outline about this topic !!! how do you think of it? lol :)
Nowadays, as the technology is developing rapidly, the massive of information gives more challenge to both teacher and student. As my mom, a teacher with 20 years of experience, said:" I think I'm trapped in a big obstacle, my students are more and more tough, my teaching skill seems cannot meet present requirement." While some people hold that technology construct a immediate and access-easily bridge between teacher and student, I claim that it is harder for my mon and other teachers to teacher than it was in the past.
Admittedly, high-tech equipment is beneficial for teaching.
Receiving more and more information, students are capable of suspect all the conclusion from teacher.
Teachers are supposed to make tireless efforts to keep up with developing knowledge and science.
To sum up, the new challenge from students and changing world cannot be counterbalanced by several high-tech tools. My mother, alone with many other teachers, are facing unprecedented challenges, in the meantime, it can elicit teacher's potential ability to contribute a more comprehensive and advanced education to students.
