The category with the lowest percentage is psychomotor skills. I would guess because it relates to the movement of writing which would be difficult to replicate with technology. There are also gaps with evaluating learner progress, providing encouragement, and managing learner profiles. I think that these areas would probably need a human solution. For creative writing, I feel that evaluation would be very difficult with a computer because it depends on imagination and style. Also (not being an English teacher) I would think that evaluating a student’s efforts would also depend on a student’s progress. Also encouragement on computer programs tends to be rather basic, one of several choices. It would be adequate for operations of writing, spelling, grammar, etc.
I think that applications will continue to be developed for educational purposes. 8-12 is currently the most common age range, I think this will likely continue with 4-7 also being developed. I think technologies will work on basic skills like spelling and grammar and also promoting creative writing.
