why is that most of MHS's lecturer so "antique"?

if we can make the lecturers line up in one line, 75% of lecturers will be very antique.. like old beetles that had broken the engines.. most of them will teach an old way to do procedures (which is very different with the new ways).. maybe that had many years of experience in nursing field.. but i cant get it why is that when in practical area, they just cant get anything right?? they can be very clumsy sometimes.. i had saw once, a lecturer who had 20years of experience, trying to teach about how to insert a ryles tube into patient.. the patient was a boy and when she had inserted it, the boy was vomiting his gastric+bile juices non-stop.. the ryles tube wasnt really inside the boy's stomach! poor boy.. luckily the sister came and fixed the things up.. are the lecturer trying to teach us how to kill a patient?? and some of them had broken english.. sometimes, i am struggling to think what they said in front of class.. maybe if the class is malay medium, it wont be a big deal.. but think of it, which hospitals will accept nurses who cant even speak english?? i mean private hospitals in this case.. as a private student, it is very difficult to enter government hospitals unless u are sponsored by government hospitals.. i know many fresh graduated nurses from private college that is still sitting at home waiting for offer.. i'm not saying that it is impossible to get a place in government hospitals, but it's a rare chance if u are not under them.. continue with the lecturers, i can see how forgetful they were (in harsh word, senile maybe).. maybe not all of them.. but i can clearly see that in our lecturers.. yesterday she said this, and tomorrow she will forget them.. half of them dont even know how to teach! the worst is they will read the slides (which is prepared by someone else) like we cant read it ourselves, and in some part, they dont know what is put up in the slide.. they just took it and read it.. even my primary school brother can read like that..
