In the digital era, written communication for children and youth is changing. As texts and media include complex intersections of print, image, sound, and other modalities, the ways in which writing is conceived is shifting. The evolution and impact of digital technologies follow a long history of invention, innovation, and change in written communication, with critiques of writing and communication technologies present in both historical and contemporary contexts. A new development in contemporary digital culture is the significant and widespread participation of children and youth in digital media and communication due to the ubiquity, affordances, and appeal of mobile digital devices. In the history of writing instruction, pedagogical approaches and perspectives have continued to evolve, with the teaching of writing at times positioned as subordinate to the teaching of reading, a pattern that has repeated into the digital era in which an emphasis on digital writing production and text creation has been similarly less of a focus than receptive consumption of media. Shifts in digital practice and the emergence of new devices for writing present both challenges and opportunities for the teaching of writing and the creation of texts in schools, with issues of digital resource provision and access to technology presenting hurdles for some teachers. Teacher awareness of the digital worlds, practices, and “funds of knowledge” that students are bringing to the writing classroom is vital to reimagining the writing classroom within contemporary digital culture. In the 21st century, writing instruction needs to be inclusive of the operational demands of writing as well as sociocultural and critical requirements, in addition to responding to fluid technoliteracy contexts and consideration of how “writing” itself is changing.
