Expanding the space of f2f: Writing centers and audio-visual-textual conferencing
Able to link tutors across distance while closely approximating the tenor of face-to-face tutoring (f2f), synchronous audio-video-textual conferencing (AVT) is a semiotically rich medium that sustains critical “social cues” and enhances interaction and exchange. The authors theorize and demonstrate the potential of synchronous digital exchange, including functions that surpass the affordances of paper-based f2f tutorials—such as real-time modeling and web-based referencing.
