What I will say, however, is that, while we are debating whether or not to continue using printed text books in our comfortable first world, there are teachers in schools where there is no alternative to text books – and I think they may well be in the majority. Many of them have never seen a computer and there is no electricity to run one, even if they had. The text books they do have are in short supply, outdated and in poor repair. We took some of our surplus text books to that school and the teachers wept, while the children sang, danced and clapped their thanks to us. “Die tannies het boeke gebring, julle!” (the aunties have brought books, you lot!). That moment changed me.
