The purpose of this chapter is to present peer group mediation as one of
the assessment practices within Teletandem Brasil, a Virtual Exchange (VE)
project which uses tandem practice between university students of different
countries for foreign language learning, carried out through
videoconferencing tools. Peer group mediation sessions are regular meetings,
in addition to the teletandem practice, and aim at promoting reflection on
telecollaborative, intercultural, and language learning, and individual
learning processes. Assessment is seen here as a practice by students,
mediators, and peers that seeks to reflect upon and respond to information
from dialogue, demonstration, and observation in ways that enhance ongoing
learning.
