Not necessarily. If they are employed in research capacity only, then it's more than obvious that their teaching ability isn't worth considering. However, if they are employed in both a research and teaching capacity, then it makes perfect sense for such academics to at least give the impression that they know how to teach their material.jm1234567890 said:lecturer's don't exist to teach. they exist to research, so if they can't teach properly this is only minor matter.
Something else to consider is that that particular post was discussing students with poor english skills wanting/studying to become teachers, not current lecturers with poor english/teaching skills. Perhaps your own response is indicative of a lowering of english standards amongst the student body in general? (I don't mean for that to seem so strong, but it's a valid point to make given the topic).
