Aushandeln gemeinsamer Verständnisebenen in mehr-sprachiger videobasierter Interaktion.

This paper concerns practices of establishing common ground - mutual knowledge, mutual beliefs, and mutual assumptions - in talk-in-interaction between L1 and L2 speakers in videomediated interactions (VMI). Specifically, I use the theory and methodology of conversation analysis and multimodality to first investigate how L1 speakers of German position L2 speakers in multilingual interactions and how they attempt to establish common ground prior to displaying their epistemic status. In addition, this paper investigates talk and embodied practices utilized by L1 speakers of German to establish common ground with L2 speakers of German prior to demonstrating their firsthand experience and expertise in videoconferencing conversations. By analyzing practices to establish common ground, this paper demonstrates the ways in which L1 speakers establish common ground with L2 speakers, namely 1) by co-constructing the meaning of the word without even having direct epistemic access to a particular cultural product, 2) by checking L2 speaker's epistemic status, and 3) by asking follow-up questions.
