Leslie, I recently undertook PR training for academic staff and so am delighted you think my comments read like "a PR handout". ;-)

More seriously, I feel under no pressure to pass full fee paying foreign students, or anyone else. I give students small writing tasks early in a course, so those with writing problems can be referred to a special unit at the university. This is very effective at improving the writing of both students who have English as a second language and also computer science students, who tend to be better at wiring code than prose.

You can read more about how I teach students in my new blog "The Higher Education Whisperer": http://blog.highereducationwhisperer.com/
