A good lecturer can inspire even the most distractable student! If your students are talking, or not turning up, or walking out, you need to do something different!
It's when parents start supporting that attitude that the very best of teachers leave the job. I did.
For years at FE and HE I was a good lecturer. Good results, good feedback forms and all the other hoops. Slowly things changed. I started doing more of the work, I could no longer leave a lecture with a question and expect a single student to have researched the answer by the next session. I couldn't not have them know the information so I had no choice but to provide it.
Because I demanded they were more independent my feedback forms grew more and more negative, including comments about my age, my figure, my accent. I was openly derided for not being young and slim. Parents would join in with this too, it became soul destroying.
One year, in the middle of a good patch, with the majority of students being relatively self directing I had one young man for whom the world was simply an unjust place. He did not work, made no effort whatsoever other than to formally complain, long and loud about every lecturer.
The result of this was that every lecturer was asked, formally, to review their teaching practice, to attend a session on self reflection, to see if there was anything in what he had to say. During that compulsory session I handed in my notice with a 'lunatics running the asylum' comment. 2 colleagues left by the end of the same year, most of the department by the end of the following year.
That A level centre, like many others nowadays, is now staffed by a lot of part time lecturers, all newly qualified, all having to put up with attitudes like that above. They will mostly burn out within 5 years, to be replaced with more and more unprepared and unsupported newly qualified teachers. There will be no 'old lags' to reassure and mentor them through their first years.
But hey! Who cares? It's all the lecturers fault in the first place!
