Answer:
Certinly you will find text book answers in a text book.
Major and tricky issue it sounds is who does your curruculum is aimed at? There is certain domain of knowledge which is necessary for everybody to learn and there are situated knowledge domains: something is more important for a particular section of society than the other. No society is homogenous let the issue of individual differences in learning alone. Important thing is not to forget that its purely not a technical issue.
There are debates you help the good to be better or the worse to be good. You take labour needs of your country or the globe?
There is a common sense knowledge that people are interested on technical matters when they are young (including music and machinery), then they are interested on economic issues, then to social and then spiritual. It is often started with topics such as respect to elders, patriotism etc. HOWEVER, there are big issues whether skills should be already in curriculum in children's education (e.g. Crisis of Education by Hannah Arendt)?
And your dependence on connectivity - to what degree? If we are not so scared of Hannah Arendt - what will be useful tomorrow as the world is changing fast. (I think, French government in their millennium education review emphasized teaching children adaptibility - in all senses - physical, mental, skill, social relations).
I think, these are more than adequate tips if you are pursuing it seriously to go on.
