One example of this is a few years ago here at Ohio Northern University the school sent out an email to the student body giving tips on how to stay warm in the winter. The forecast was for -30 degree wind chill so the University thought it would be appropriate to help the students stay warm. There was also a frostbite warning if you were outside more than 10 minutes. The University came up with #PolarBearUp to try and inspire students and be "hip". Needless to say the students were not amused. They immediately took to Twitter and Facebook and used the hashtag to explain that a -30 degree windchill was unacceptable walking conditions. Many students had a 15-20 minute walk to class and the 10 minute frostbite warning concerned them. Memes were created as the students gained more momentum. Many sarcastic jokes were made as the students attempted to get their frustration and concern across to the faculty and administration. After four hours the students were still taking Twitter by storm. Eventually the University did decide to cancel classes for the next day and the students rejoiced.
Another example of students using Twitter and social media to communicate with faculty is Howard University. The students were concerned about conditions and the tuition they were paying. They created #TakeBackHU to express their concern to the administration. Alumni also put in their opinions saying that they experienced many of the same issues. The president finally responded that he was going to work to fix many of the problems. Hopefully he follows through on his word.
