The reason why I’m against the famous pre-req is that it punishes students like I used to be in order to spare a few ne’er-do-wells the inconvenience of having to withdraw from a course that proves to be too hard for them.
I don’t understand why we keep sacrificing the interests of good students in order to cater to people who aren’t interested in the material and aren’t making an effort.
There are people who are simply not teachable, and no amount of futzing with pre-requisites, pedagogy, textbooks, etc will change that. If they don’t want to learn, there’s nothing you can do. So I’d rather we let it go and concentrated on people who do want to be taught.
