Using less summative assessment, like standardized tests based on grade level, to compare students and set the rate of learning based on the mean of a group of children, instead, diagnostic and formative assessment using technology, like what we have seen with the Khan Academy, will be widely used to assist in the difficult often boring stage of precision giving teachers more time to introduce students new subjects and lead them to use their knowledge to make generalizations.
My prediction is the end of standardized tests at the grade level by 2030. Homework will not be necessary anymore as this will work will be efficiently done during normal school hours. Lastly, although it is important that we consider learning disabilities a real thing, it might be more fair and pragmatic to call it a teaching disability taking the responsibility from the child to learn putting it onto the adult. (Ok, this is personal, my goal for the next ten years is to eliminate homework.)
