One concern about IM has to do with the "bastardization" of language. Several articles indicate that students who use messaging on a frequent basis often use bad grammar, poor punctuation, and improper abbreviations in academic writing. According to Lee (2002), "teachers say that papers are being written with shortened words, improper capitalization and punctuation, and characters like &, $ and @. " However, something that is not always considered is that these mistakes are often unintentional – when students use IM frequently, they reach a saturation point where they no longer notice the IM lingo because they are so used to seeing it. Montana Hodgen, a 16-year old high school student in Montclair, New Jersey, "was so accustomed to instant-messaging abbreviations that she often read right past them" (Lee, 2002). As she puts it, "I was so used to reading what my friends wrote to me on Instant Messenger that I didn't even realize that there was something wrong," she said. She said her ability to separate formal and informal English declined the more she used instant messages" (Lee, 2002).This was also a problem for Carl Sharp, whose 15-year old son's summer job application read "i want 2 b a counselor because i love 2 work with kids" (Friess, 2003), and English instructor Cindy Glover, who – while teaching undergraduate freshman composition in 2002 – "spent a lot of time unteaching Internet-speak. 'My students were trying to communicate fairly academic, scholarly thoughts, but some of them didn't seem to know it's "y-o-u," not "u"'" (Freiss, 2003.) These examples give credence to Montana Hodgen's point, that heavy IM use actually changes the way students read words on a page.

Among the studies Greenfield analyzed was a classroom study showing that students who were given access to the Internet during class and were encouraged to use it during lectures did not process what the speaker said as well as students who did not have Internet access. When students were tested after class lectures, those who did not have Internet access performed better than those who did.   "Wiring classrooms for Internet access does not enhance learning," Greenfield said.

Another study Greenfield analyzed found that college students who watched "CNN Headline News" with just the news anchor on screen and without the "news crawl" across the bottom of the screen remembered significantly more facts from the televised broadcast than those who watched it with the distraction of the crawling text and with additional stock market and weather information on the screen.   These and other studies show that multi-tasking "prevents people from getting a deeper understanding of information," Greenfield said.

Emoticons, truncated and butchered words such as 'cuz,' are just some of the writing horrors being handed in, say professors and administrators at Simon Fraser. "Little happy faces ... or a sad face ... little abbreviations," show up even in letters of academic appeal, says Khan Hemani. "Instead of 'because', it's 'cuz'. That's one I see fairly frequently," she says, and these are new in the past five years. Khan Hemani sends appeal submissions with emoticons in them back to students to be re-written "because a committee will immediately get their backs up when they see that kind of written style."
