A survey of 2,462 Advanced Placement (AP) and National Writing Project (NWP) teachers finds that digital technologies are shaping student writing in myriad ways and have also become helpful tools for teaching writing to middle and high school students. These teachers see the internet and digital technologies such as social networking sites, cell phones and texting, generally facilitating teens' personal expression and creativity, broadening the audience for their written material, and encouraging teens to write more often in more formats than may have been the case in prior generations. At the same time, they describe the unique challenges of teaching writing in the digital age, including the "creep" of informal style into formal writing assignments and the need to better educate students about issues such as plagiarism and fair use.
