Books have been remote learning for hundreds of years, whats wrong with remote learning especially now pupils can ask questions straight away from a pool of teachers online?
Simply because technology was slow back then, if the technology existed for faster than horseback/carrier pigeon communication and costs were not prohibitive would the world of teaching/knowledge acquisition have evolved a different form of society?
The biggest problem is that a huge component of school is socialization. Interacting with other kids in an low-control setting.
Much like conferences the "hallway class" is a huge component.
Ass onto that that many kids are bad at focusing on online classes and the whole situation is not up to the standard of in-persin schooling (with current systems).
