The front end of this program is very confusing for children (and teachers). Why do children have a password, a secret name and a monkey name ... where are these explained. There should only be one login name for a child to use.
The idea of monkeys might appeal to 5 year olds, but older children find them "dumb".
It is not clear how one skips the early lessons for a slightly more advance student.
While some children might see the gane following each lesson as a reward, other children find them a real irritation and just want to get to the next lesson. It is not clear whether one can skip the game.
This program does not appear to have been rigorously tested with real children
