Applying the Zulu community-based problem-solving concept of Ubuntu-best translated as "I am because we are"-M-Ubuntu uses inexpensive, low-threshold mobile phone technologies to promote mobile literacy (m-literacy) by empowering local teachers to connect to each other and to literacy coaches in the United States. M-Ubuntu focuses on two reform-minded schools and their enthusiastic teachers and learners-Spectrum, near Johannesburg, which contends with crime and other social dislocations accompanying urbanization, and Ramosadi, located near Botswana, which struggles to serve orphans-and links teachers in primary schools across South Africa.
