Impact of recent student edits  This article has recently been edited by students as part of their course work for a university course  As part of the quality metrics for the education program we would like to determine what level of burden is placed on Wikipedias editors by student coursework  If you are an editor of this article who spent time correcting edits to it made by the students please tell us how much time you spent on cleaning up the article  Please note that we are asking you to estimate only the negative effects of the students work  If the students added good material but you spent time formatting it or making it conform to the manual of style or copyediting it then the material added was still a net benefit and the work you did improved it further  If on the other hand the students added material that had to be removed or removed good material which you had to replace please let us know how much time you had to spend making those corrections This includes time you may have spent posting to the students talk pages or to Wikipedia noticeboards or working with them on IRC or any other time you spent which was required to fix problems created by the students edits Any work you did as a Wikipedia Ambassador for that students class should not be counted  Please rate the amount of time spent as follows   No unproductive work to clean up    A few minutes of work needed    Between a few minutes and half an hour of work needed    Half an hour to an hour of work needed    More than an hour of work needed  Please also add any comments you feel may be helpful We welcome ratings from multiple editors on the same article Add your input here Thanks
