Teacher's little helper

摘要

AT KICOSHEP SCHOOL in Kibera, a vast Nairobi slum, Grade 3 is learning English. The teacher, Jacinter Atieno, asks questions about a story on the exploitation of children as domestic servants. At the back of the class, a coach logs information about Mrs Atieno's performance into a tablet. Halfway through the class, the coach summons three children and tests their reading. The scores go into the tablet, which then makes suggestions-that, say, Mrs Atieno might watch one of its instructional videos, or improve her English pronunciation with its letter-sound tool. The information is uploaded to the county office that runs the local schools, and can be reviewed by the teachers' bosses there.
