Thousands (millions?) of teachers prepare mostly the same lessons every day. Whilst some preparation is obviously necessary, I see huge benefits for students and teachers from centralising this.
I am looking forward to the future when a video lesson distributed to 20% of children on the Monday can have its feedback aggregated and analysed, with a patched version of the lesson pushed out on Tuesday.
For example, imagine teaching a maths lesson, and seeing that a significant number of children paused and rewatched a particular 20-second section. You could re-film that and splice it in ready for testing the next day. Imagine the possibilities if you had schools offset their holidays by a few weeks!
> teachers prepare mostly the same lessons every day
That "mostly" hides a lot. A good teacher will prepare this lesson in a context: context of his pupils, their abilities,
their knowledge of other material, etc.
I don't see how an individual teacher has the advantage. Most classes have a huge range in ability and any lesson must be suitable for all. A centralised system could (in my dreams) deliver more than one version of each lesson and determine (from their enormous amounts of data) which lesson each child will benefit most from.
Of course if I'm dreaming that much I should point out that with each child able to learn at their own pace a single physical classroom could hold many different levels of the same subject at once, with children from different schools working together...
It is no coincidence that the biggest proponents of this style of learning have strong AI backgrounds. Their vision is a centralized system that can deliver that highly customized material on a per-student basis. It is still early days, but the technology has a lot of room to evolve over time.
So who is making the site that will deliver more personalized instruction? Where is the research that site will use, telling all about which kinds of personalization are proven and how much effect they will have?
