I haven’t been in a classroom for over 50 years except for parent teacher meetings,( I am not in the education profession) but I can still remember the time when a teacher was out of the classroom for a few minutes and one student ran outside and brought a dog and hid it under the teachers desk. When the teacher moved the chair to sit down the dog ran out. Until order was restored it was over an hour.
Maybe students changed since I went to school, but I think if given the chance the average student and similarly the average worker would goof off. Which is why most students are taught in a school environment as opposed to independent study and likewise workers are closely monitored.
I will admit in theory it could work but in real life it wouldn’t. If you think it’s a good idea speak to your school administrators see what they think not someone in the coffee room. Start out with one class see how it works and the expend to a whole grade. It may work depending on how dedicated the students are.
