Hi. I'm new to this site and it looks pretty helpful and I have a question so here goes... I'm a high school English teacher and my seniors have just handed in their senior papers worth 25% of the marking period's grade (all the seniors in our school must do this). I made the due date today. My students have told me that their other teachers let them hand things in through e-mail rather than bring a hard copy and have asked me a few times if I would allow them to do this as well. I finally made the class take a vote on it and almost all of them wanted to hand papers/essays in through e-mail. The senior paper was due today. I did not get an e-mail from one of my students with the paper (and I have repeatedly checked my inbox and have actually made this e-mail address just for my students so it would not get mixed in with my mail from family/friends,etc.). I have actually had this girl for 3 out of her 4 years of high school and she's never handed anything in late, always does her work, etc. I asked her about it and she swears she sent it. I usually have a zero tolerance policy with late work especially with essays and the senior paper is the most important essay of the year. I don't have much knowledge about e-mail but I thought whenever you sent an e-mail it would always go through? Is that not the case? Could there be a chance that she sent it and I didn't receive it? If it helps she had AOL e-mail and I have yahoo.
