On the subject of students/children teaching teachers/parents, this reversal of traditional roles needs support and change of attitude from the teachers and parents and won't come easy.
My daughter, who learns Mandarin at school and speaks English elsewhere except occassionally Cantonese at home, played with a 2 and half year old boy who only speaks Mandarin last night. During the time, the boy brought a piece of Lego to her and asked (in Mandarin) what it was. My daughter was thinking how to answer and before she came up with an answer, the little boy told her the answer that it was a toy (in Mandarin). He kept on repeating the word toy in the hope of teaching my daughter how to pronounce it. The immediate reaction of my daughter was that she was suppose to teach the little boy, not the other way around.
Oh, if a 14-year girl has already developed this sense of uni-directional teaching attitude, the roles of teachers and parents to play the recipient role will need great change of attitude. Hope the Netherlands Safe Internet Day work out well. Please keep us posted, Josie Fraser.
