Not saying you are wrong or right, but for many kids having an adult who simply cares is worth infinitely more than any amount of efficiencies or base material.
Taking care? Motivating? Observing listening analysing what is happening in that temporary microsociety you manage? Prepare lessons, research extend your own knowledge? React to what is Happening changing the course of your lessons to react to what actually happens in the classroom? Have conbersations with kids and parents? Judge if the production of these little ones shows progression? Figure out what potential problems might be (structurally socially psychologically). Have humor, and dedicate some time to just simply forming a bond? Damn I cant think of a lot that could be automated besides the officework where the same tools are used as everywhere for scheduling, dicumentation communication etc...
