the negotiation they had about what they believe is the best option for the learning of lan- guages in a teletandem approach. The decision to postpone the interaction session empha- sizes the fact that collaborative learning enables learners to express their points-of-view, by discussing them and making decisions about the problems they face while interacting in a virtual context (VASSALLO & TELLES, 2009). The whiteboard was also used by the participants as an aid to communication and, by extension, to language learning. Peregrino, for example, uses the whiteboard as a comple- mentary resource to illustrate what he was explaining to his partner, as can be seen in Ex- ample (3): Example (3) Interaction via Openmeetings—September 3rd, 2010 Jujuba: Emission… Peregrino: Do you see on the whiteboard? Like this one would be a normal and you have another scenario, just like this, so you have a reduction here to here, and this reduction, hum, costs something (Peregrino draws on the whiteboard while he t alks about carbon emission). Jujuba: Hum, ok. Peregrino: Here on the left is like… hãa… […] Jujuba: Hã? Peregrino: (He writes ‘carbon footprint’ on the whiteboard). Like this, (Explaining from the two pictures he had drawn on the board) You have one scenario. It’s like when a tourist comes to Rio and he goes to the beach and to the clubs or another stuffs, that’s the left scenario, the trip like one week, that they stay in Brazil, ah, how much emissions will be emitted? And the other scenario would be, for ex - ample, Chapada or Pirenópolis, they’re doing sustainable tourism and there would be less emissions, so we calculate them both and then we, we make a comparison. What do you think? In Example (4), Natalie makes use of an electronic dictionary to help her in the pro- duction of messages in English. She was talking to her partner about Brazilian typical food and she introduces a kind of fruit which is used in the cuisine of the Central-West region 1178
