At a multinational company, daily written communication between staff, supervisors, customers, and suppliers is frequently conducted using digital tools (e.g., emails, smartphones, and texting applications) often across multiple nationally, linguistically, and conceptually defined borders. Determining digital tools’ impact on intercultural encounters in professional environments like these is difficult but important given the sheer volume of digital contact in technical and professional environments and the ongoing global struggle to broker peace and productivity amid communities’ many perceived differences. Using examples drawn from a case study of binational manufacturing sister companies, I build on recent work in professional, networked written communication to analyze two WhatsApp exchanges, one between a central study participant and his customer, another between the participant and an employee. This study shows how asynchronous digital communication tools created complex “silences” in writing between participants. In these silences (e.g., a lack of or delayed response to a text) individuals try to explain others’ actions for themselves. Drawing on a combination of third-generation activity theory and Latourian actor-network theory, I show that while explaining others’ actions in writing with whatever cultural shorthand is available may remain a common part of everyday life and research, it can be a poor guide for explaining others’ actions, especially in digital writing. My study shows how research of, and instruction in, digital tool use in intercultural writing contexts requires attention to the material conditions and objectives potentially shaping one’s own as well as others’ composition choices.

Frequently writing is now no longer the central mode of representation in learning materials—textbooks, Web-based resources, teacher-produced materials. Still (as well as moving) images are increasingly prominent as carriers of meaning. Uses and forms of writing have undergone profound changes over the last decades, which calls for a social, pedagogical, and semiotic explanation. Two trends mark that history. The digital media, rather than the (text) book, are more and more the site of appearance and distribution of learning resources, and writing is being displaced by image as the central mode for representation. This poses sharp questions about present and future roles and forms of writing. For text, design and principles of composition move into the foreground. Here we sketch a social semiotic account that aims to elucidate such principles and permits consideration of their epistemological as well as social/pedagogic significance. Linking representation with social factors, we put forward terms to explore two issues: the principles underlying the design of multimodal ensembles and the potential epistemological and pedagogic effects of multimodal designs. Our investigation is set within a research project with a corpus of learning resources for secondary school in Science, Mathematics, and English from the 1930s, the 1980s, and from the first decade of the 21st century, as well as digitally represented and online learning resources from the year 2000 onward.
