I am really apeechless 
 
thank you all for posting all those replies in this short time
 
thank you all and thanks AB for the link .. 
 
 
 
well, another point came up in my mind while i was reading your comments .. 
 
a guy in the 1st page mentioned the habit problem 
 
that �s one thing that I always keep in mind 
 
I believe that delaying corrections is something that is very sensitive
 
if you delay a correction you will need a very strong way to correct the error when you decide to correct it 
 
but if you correct it at least on the same day you can use a soft way to be sure you don �t attack the student
 
the problem is that we are talking about teenagers ( i �ll be teaching intermediate or highschool students) 
 
this age is very scary .. and each generation is getting more and more sesitive 
 
a word can shut off the student and make him hate the whole school 
 
that �s the problem in my country (I �m not sure if this exists in somewhere else)
 
but as rozianne said ... the teacher is the one who creates the atmosphere 
 
as i mentiones its also a must in my country to re-define many things 
 
in my country teachers are there just to evaluate which is very bad 
 
the student should always be right 
 
that �s why they �re scared of making mistakes
 
I wish i could just make a change in my country 
 
 
thank you all for helping me out
