Student essay editing...==
Andy, if you are so keen, then you are encouraged to make the improvements.  These contributions are inferior in many ways as is being widely discussed not only by myself but others.  The rest of us have day jobs, so limited time to contribute.  As you probably know from your teaching experiences, repairing student essays take hours of effort and time.  Sincerely said, I just dont think that these unsupervised contributions from students are of the technical or stylistic standards we are accustomed to in Wikipedia.  The graphics are copyright violations, the article are often violate WP:NOTTEXTBOOK and are preachy or making value judgements.  The referencing ignores WP:SECONDARY.  If you find these massive additions, salvageable, then you can join the completely absent instructor in editing.  We really hope that you can help with content!    
I find your mass removal of good faith contributions by new editors, and your repeatedly pejorative descriptions of them, both outwith the spirit of Wikipedia (WP:BITE, WP:AGF), and disruptive (WP:POINT). If you are too busy to make fixes, that's OK, you are not personally required to do so - just leave the material for others to fix.  (Pigsonthewing); Talk to Andy; Andy's edits 
As I have already indicated, at that stage in my traiing would have submitted similarly awful essays. So my pejorative comments are directed at the so-called ambassadors-coordinators-instructors who foster and protect such inappropriate and poorly crafted content.  Like you, they are waiting and praying for someone with writing skills to intervene.  But as you're discovering, determined mediocrity can be difficult to rectify within the fringes of Wikipedia.  Looking forward to your help with editing these and other articles.   
Those people may have been your intended targets, but that's quite clearly not the result you achieved; here as elsewhere. And no, I do not pray.  (Pigsonthewing); Talk to Andy; Andy's edits 
There is no result to be achieved ... the students dropped their essay bomb on Wikipedia and got their grades.  The ambassadors-coordinators-instructors are flush with approval that they are "encouraging" and "nuturing" and being innovative in their engagement of Wikipedia.
