It may be the same for any level of professional incompetence. It’s not that hard with English. If the teacher keeps students in the dark, students don’t even know how incompetent the teacher is. It’s harder to bluff one’s way through with computers. I guess that’s why they just keep the room locked.
I have seen graduates from overseas MA programs typing with two fingers. Some people can type quickly with two fingers, but these people could not. At the rate they were typing, it would take three years to type the first draft of a dissertation. No wonder I’ve never gotten email from them.
When it comes to teaching computer programs, a sufficiently confusing explanation will keep students clicking aimlessly. Then the teachers can just blame them. “See? Students from the countryside don’t know anything.”
Who is it that doesn’t know anything? I heard that an international organization paid big bucks for teachers to train in computer literacy in Vientiane, innocently letting the school decide who could go. They came back with two fingers, but that was about it. But that's OK. At least it's not spoiled meat.
