Reviewing my practice as language teacher using the 3 modes of communication as a framework I did notice that, I do focus on the 3 modes, Interpretative, Interpersonal and Presentational however, I need to improve a lot working simultaneously all 3-communication modes on the same unit.
My students do Teletandem but from now on I will ask them to also write in the target language what they learned through the interaction and present for their classmates. The students can search online to prepare their presentation.
