A modern day teacher problem

I am a teacher. I have now been teaching math for more than ten years. Considering students' behaviour, I can say, in general, that students are losing their interest year by year. Maybe this began since more facilities have gradually become available to them. Everything they want is here. A big source of motivation is to look to a better future. But it seems that they care only for the present.

very well written!

(Problems Facing Teachers Nowadays)

I am a teacher. I have an experiment experience teaching math for more than ten years (or: I've been teaching math for more than ten years, or: I have ten years' experience in teaching math). Considering students' current learning tendencies, I can say that the students they are losing their interest year by year. Maybe, it happens since this is happening because, day by day, more facilities is are available to this generation (or: to them). Every thing they need is ready. A big source of motivation is used to be to try to have a better future. But it seems that they like to prefer to live in the present time (or: are more preoccupied with the present).

-I would say "Challenges" instead of "Problems" = Challenges Facing Teachers Nowadays

-also: if you want to say teachers' problems - you need the apostrophe. You cannot use "Nowadays" to characterize "the problems" like an adjective - you can say: one of the teachers' current problems. Nowadays means "in these days" or "the present" or "at this time", and is used as an adverb or a noun.

-When talking about jobs you need an article (a/an) e.g. a doctor, an engineer etc..

-An experiment is a scientific (or non-scientific) test, that you do to answer a question, discover something etc

-When you say "a big source of motivation is", it sounds like you mean it still is even now - but you're saying it's no longer a source of motivation for this generation.

-Instead of "Maybe this is happening" I would personally say: This could be happening because .., This could be the case because .., A reason for this could be that .., One explanation could be .., This is likely happening (because / due to the fact that) ..

-Instead of "Try to have a better future" I would personally say: Try to secure a better future

-Instead of "everything they need is ready" I would personally say: (Readily / immediately) (available / accessible) ± to them (through the internet etc..)

Hope this is helpful!
