"I remember Salman Khan (of Khan Academy) talking about this a few years ago. He believed that the current accepted method of teaching - students attending lectures and sitting in classrooms getting knowledge from teachers, then later doing homework alone trying to apply it - needs to be inverted. Lectures, presentations, textbooks can all be online and automated. Teaching resources, limited as they are, are much better spent helping students specifically when they are stuck and need more personalized help. Of course this brings us to the more fundamental question - are schools more for learning or daycare?"

- OneGuy123 6y agoThis. Teachers speaking in front of the blackboard is overrated, anyone can do that. In fact it is precesily this part that a student can go and find on the internet explained in 30 different ways if he still doesn't get it.
- pps43 6y agoI beg to differ. One of my most vivid educational experiences is of my teacher calculating approximate square root on the side of the blackboard when he needed it for something completely unrelated. To me it felt like he was riding a unicycle or swallowing a sword. Seeing that the audience was perplexed, he reluctantly took a five minute detour and explained Newton-Raphson algorithm, at which point the unbelievable circus trick suddenly became trivial.

- rvn1045 6y agoI doubt the majority of students are even paying attention. I can't imagine a 10 year old being able to focus on lectures for several hours a day. Most are just day dreaming.
- imglorp 6y agoThis is easily achievable with current ratios. Self directed video time, some solo practice time, plus an hour of 1:1 time a week would work out to N instructor hours for N students. So N=25 would be about current levels.
