the Primer should not replace the human teacher but assist her (e.g.by keeping track of what individual children know and do not know)
adapt the Primer to the child and not child to the Primer (all our speech recognition models run on our own servers / local hardware and can easily adapt to a concrete pupil or group of pupils)
as the child learns, so does the Primer (we call this "Human Machine Peer Learning")
Achtung, Gefahr: !!! by focusing too much on the technical, AI-related side of things, one may easily fall into trap of poor pedagogical practices !!!
