…ost successful authors in history, got dozens and dozens of Fs before he got his first real life A. School trains us to have the mindset that a given amount of effort will always bring a measurable, predictable, and successful result. The real world doesn’t work like that.
Assuming the teacher shifts into the role of a guide or moderator who gives questions without predetermined answers, the resulting discourse will not be easily contained within the borders of content-based subjects. When that happens, the whole notion of standardized curriculums centered around pre-approved answers will become pointless. As for flexible scheduling, we only need to fully use our existing communication technologies which allow for a global education system that enables delocalized learning at any time.
For example, unless you teach who the great authors of the past were, there shall be none. If you focus on practical money-making skills, people will know nothing of things like philosophy or poetry and will not be able to do or appreciate them. If you let parents home school, you’ll empower their influence over their children’s beliefs greatly, probably reinforcing traditions. If there always are winners and losers or segregation in your education system, people will form cliques early on and stick to them indefinitely. Etc.
