The study examined sixth, seventh, and eighth graders in Pennsylvania. S. Shyam Sundar, who supervised the study, says the reason students perform worse on grammar tests is because texting is not actually a different language. It therefore works its way into the classroom, homework, and all facets of language.
In other words, texting too much can cause students to think this shorthand is a proper way to write.
At this rate, it wouldn’t surprise me that grammar continues to worsen as attention spans decrease, Twitter makes everyone talk in 140-character snippets, and texting keeps students unable to master grammar.
So how do teachers combat this? Sundar recommends giving students writing assignments that require longer form answers, formal language, and actively require students to shy away from shorter answers.
