"I see a lot of writing that has text language: 'ur' for 'your' or not capitalizing words," Woollven said. "For kids who have grown up texting and instant messaging, it is pretty engrained. It is something you have to keep reminding and keep looking at."
According to the report, 40 percent say digital technology makes students more likely to use poor spelling and grammar, although 38 percent say it is "less likely" to cause those mistakes.
There is also the effect of the speed of the new technologies. Forty-six percent of teachers said that digital tools have made students write too fast, causing mistakes and carelessness. "They are bombarded by so much and they are used to things quickly posting on social networks," Woollven said. "They aren't always thinking about revising."
In focus groups, teachers shared with the Pew authors that the shorter and more concise forms of digital social expression seem to affect students' ability to read and write longer texts.
Still, many teachers -- and according to Pew's numbers, the majority of teachers -- believe that tech is only making writing stronger in certain aspects. And many teachers are up for the new challenges.
"Teachers have been complaining about the declining standards of writing for what seems like 150 years," Malley said. "I disagree with that. They [students] write differently for me than they do on their Twitter accounts, and if they don't, it's my job to let them know what the difference should be."
