Whatsapp in Afrikaans

One of our Afrikaans teachers makes use of Whatsapp to have short bouts of communication about everyday life (in Afrikaans, of course). He has noticed that those who have the opportunity to converse in Afrikaans everyday improve significantly. Unfortunately the curriculum is too full to allow fully conversational classes. Email does not allow for quick conversations. Most of his class use Whatsapp and the learners are comfortable chatting to two or three people at the same time. Using their proferred communication means he has increaded the likelihood of a quick Afrikaans chat! He is initially experimenting with one class and has discussed the rules with them. Anyone who behaves inappropriately will be blocked!  So far so good!
